Description

Service trigger method and system

technical field

The present invention relates to the communication field, in particular to the technology of service triggering.

Background technique

IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is an IP multimedia subsystem defined by the 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization partner project) standard. It is a 3G (3rd Generation) mobile network that implements packet voice and packet data. , providing a unified target network for multimedia services and applications.

At present, other international standard organizations, such as ITU-T (International Telecommunication Union-Telecommunication Standardization Sector, International Telecommunication Union-Telecommunications Standardization Sector), ETSI (European Telecommunications Standards Institute, European Telecommunications Standards Institute), etc. also adopt IMS as their definition The core network of the generation network.

IMS uses the IP packet domain as the bearer channel for its control signaling and media transmission, and uses SIP (Session Initiation Protocol, Session Initiation Protocol) as the call control signaling to realize the separation of service management, session control and bearer access. Among them, the SIP protocol is an application layer control protocol for establishing, changing and terminating multimedia sessions or calls. These multimedia sessions include multimedia conferences, distance learning, Internet telephony, etc. Its core is defined by the IETF standard organization.

In IMS, the session layer and the service layer are separated. The prior art related to the present invention provides a method for implementing service triggering in IMS, which includes:

Step S101, defining possible services or service sets;

Step S102, when the user orders/modifies the service subscription relationship, create user-specific service data in the form of iFC (Initial Filter Criteria, initial filter rule);

iFC is a service trigger filtering rule. Specifically, iFC includes service trigger conditions and their corresponding AS (Application Server, application server). The service trigger conditions are described by SPT (Service Point Trigger, service point trigger). The contents include: Request-URI (request-uniform resource identifier), which is used to identify the resource pointed to by the SIP initial request; SIP Method (SIP method), which indicates the type of the SIP initial request; SIP Header (head field), which contains the The information related to the SIP initial request can be any SIP header field and the content of the header field; Session Case (session situation), there are three possible values, that is, start, end or end unregistered; Session Description (session description), Any SDP (Session Description Protocol, Session Description Protocol) field content in the SIP method.

Step S103, when the S-CSCF (Serving-Call Session Control Function, service-call session control function) entity receives the SIP initial request, execute iFC according to the current session situation and the received SIP initial request message, when the trigger source When the content matches the service trigger condition, determine the application server corresponding to the current session situation and the SIP initial request, and deliver the received SIP initial request to the determined application server.

It can be seen from the above existing technologies that the iFC file and the content of the SIP initial request message received by the S-CSCF entity are two important factors that determine the direction of service invocation. The content of the trigger source is displayed. When the content of the trigger source matches the service trigger condition, the service call direction, that is, the corresponding application server, is obtained.

At present, standard organizations such as 3GPP and MSF (MultiService Forum) are still continuing to study the service provision method of IMS. For example, MSF proposes that two service point triggers, call status and schedule, should be added to the trigger conditions of service calls. At the same time, a new functional network element ServiceBroker (business agent) is introduced to handle service calls. In addition, there are other standard documents that propose to add new service point triggers such as location information to the trigger conditions of service calls. , to provide a richer service trigger method. However, the new service trigger information described by these new service point triggers is either not included in the content of the SIP initial request message received by the S-CSCF entity, such as call status; The content of the SIP initial request message sent may carry location information, such as an emergency call, while ordinary calls do not carry location information. For the convenience of description, this type of communication cannot be fixed from the initial request message sent by the message originator. The obtained service trigger source content is called "service trigger enhancement information". The originator of the message may be a user terminal, or a network element or the like. The communication initial request message may be a SIP initial request message. It can be seen that the existing technology cannot collect these service trigger enhancement information through the S-CSCF entity, and furthermore, the service trigger function cannot be executed according to the service trigger enhancement information to determine the direction of service invocation.

Detailed ways

Embodiments of the present invention provide a service trigger method and system, which can collect service trigger information that does not appear in the content of the SIP initial request message sent by the user, and use the collected service trigger information as the trigger source content and service trigger conditions. Match to determine the direction of business calls.

For ease of description, in the embodiment of the present invention, the service trigger condition corresponding to the "service trigger enhancement information" is called "service trigger enhancement condition", and is set in the service trigger filter rule (such as iFC), and the service trigger filter Other service triggering conditions in the rule are called "common service triggering conditions".

When it is necessary to distinguish between service trigger enhancement conditions and common service trigger conditions, the special flag "service trigger enhancement condition flag" is used in the service trigger filter rules to identify the presence of service trigger enhancement conditions in the corresponding service trigger filter rules. Identify all business trigger enhancement conditions, and also identify the types of service trigger enhancement conditions. For example, a service trigger condition is set to be related to "presence (user presence information)", and a "service trigger enhancement condition flag" is set at the same time,

Taking iFC as an example, the "service trigger enhancement condition flag" can only identify the existence of a service trigger enhancement condition in a service trigger filtering rule. The following is an example of an iFC fragment:

<InitialFilterCriteria>

<EnhancedTriggerIndication>1</EnhancedTriggerIndication>

<TriggerPoint>

<SPT>

<Presence>Meeting</Presence>

</SPT>

</TriggerPoint>

...................................

</InitialFilterCriteria>

In the above example, the initial filtering rules are described between <InitialFilterCriteria> and </InitialFilterCriteria>, and the service trigger conditions are described between <TriggerPoint> and </TriggerPoint>. As mentioned above, service trigger conditions are determined by The SPT description of the service point trigger. In the example, an SPT describing user presence information is given. Between <Presence> and </Presence>, the user presence information is given as the specific value of the service trigger condition "Meeting (in the meeting )", "EnhancedTriggerIndication" is the "service trigger enhancement condition flag", and a value of "1" indicates that there is a service trigger enhancement condition in the current iFC.

"EnhancedTriggerIndication" can also be described in SPT, the example is as follows:

<SPT>

<EnhancedTriggerIndication>1</EnhancedTriggerIndication>

<Presence>Meeting</Presence>

</SPT>

The method of "service trigger enhancement condition flag" identifying a service trigger enhancement condition in a service trigger filtering rule can also be as the following iFC fragment example:

<InitialFilterCriteria>

<TriggerPoint>

<ESPT>

<Presence>Meeting</Presence>

</ESPT>

</TriggerPoint>

...................

</InitialFilterCriteria>

In the above example, in order to distinguish the enhanced service trigger condition from the normal service trigger condition, an ESPT (Enhanced Service Point Trigger, enhanced service point trigger) is given to describe the enhanced service trigger condition, in <ESPT> and </ESPT The description between > is a service trigger enhancement condition. Here, ESPT itself is the "service trigger enhancement condition flag". When ESPT exists in iFC, it means that there is service trigger enhancement condition in iFC. At this time, if the flag "Presence" is further added, that is, the ESPT and the parameters describing the service trigger enhancement condition are used together as the "service trigger enhancement condition flag", the type of service trigger enhancement condition can be identified, that is, "ESPT " and "Presence" are used together as the "service trigger enhancement condition flag" to identify the type of service trigger enhancement condition is user presence information.

Similarly, if the above-mentioned "EnhancedTriggerIndication" located in the SPT and the label describing the service trigger enhancement condition in the SPT are used together as the "service trigger enhancement condition flag", it can also identify the type of service trigger enhancement condition, that is, "EnhancedTriggerIndication" and "Presence" Together as the "service trigger enhancement condition flag" to identify the type of service trigger enhancement condition is user presence information.

The logic diagram of the network architecture implementing the embodiment of the present invention is shown in Fig. 1, including: a user data storage unit, a service trigger information collection unit, a service trigger unit and a service control unit.

Wherein, the user data storage unit is used to store user data, such as the service trigger filtering rules of user subscription, there may be a single or more than one user data storage unit storing different user data, and in practical applications, it may be HSS (Home Subscriber Server, home subscriber server), CLF (Connectivity session Location and repository Function, connectivity session location and storage function), Presence (presentation) server and other network elements.

The service trigger information collection unit is used to collect various service trigger enhancement information. There may be a single or more service trigger information collection units that collect different service trigger enhancement information. In practical applications, it may be an independent network element , and can also be located in network elements such as S-CSCF, Service Broker, SCIM (Service Capability Interaction Manager, service capability interaction manager), user data storage unit, etc.

The service triggering unit is responsible for triggering the currently processed communication to the service control unit according to the service trigger filtering rules, and the latter provides business services. In practical applications, it can be located in S-CSCF, Service Broker, softswitch (softswitch), etc. In the network element.

The service control unit provides various service logic control functions and is the host execution environment of various services. In practical applications, the service control unit may be network elements such as AS (Application Server, application server), traditional intelligent network SCF (Service Control Function, service control function).

The user data storage unit and the service trigger information collection unit communicate through the E4 interface, and the protocols used by the E4 interface include but are not limited to: Diameter protocol, SIP protocol or internal interface protocol;

The user data storage unit communicates with the service trigger unit through the E2 interface, and the protocols used by the E2 interface include but are not limited to: Diameter protocol or internal interface protocol.

The E1 interface communicates between the service trigger unit and the service control unit, and the protocols used by the E1 interface include but are not limited to: SIP protocol, INAP (Intelligent Network Application Protocol, Intelligent Network Application Procedure Protocol) protocol, and internal Interface Protocol.

The first embodiment of the present invention provides a service trigger method, the process of which is shown in Figure 2, including:

In step S201, the service trigger information collection unit collects service trigger enhancement information; and, the service trigger information collection unit acquires service trigger enhancement conditions.

The service trigger enhancement information includes call-independent user static data, call-related user dynamic data, network policy trigger information, and the like. The service trigger information collection unit may collect service trigger enhancement information unconditionally, or collect corresponding service trigger enhancement information according to service trigger enhancement conditions.

Wherein, the user static data includes: user presence information data, user geographic location information data, user terminal capability data, user preference setting data, and the like.

The call-related user dynamic data includes user call state data and the like. Among them, the user call state refers to the process state of the user's current call, such as call attempt, ringing, answering, no answering, busy, idle, etc., in intelligent services, it is also called DP (Detection Point, detection point) .

The network policy trigger information refers to the policy data that its corresponding service trigger enhancement condition is set by the network (operator) to solve a certain type of service trigger problem, such as the service trigger enhancement condition is "the user has configured on the service control unit The service control unit is allowed to be triggered only after the service application data has been received”, “A service control unit must be triggered only after other service control units have been triggered”, “A service control unit must be triggered when other service control units have not been triggered”. are allowed to trigger", etc.

In step S201, the service trigger information collection unit may obtain and record the user static data from the message content.

Wherein, the message includes: registration message (SIP REGISTER message), notification message (SIPNOTIFY message), release message (SIP PUBLISH message), Diameter message, internal interface protocol message, etc.

The service trigger information collection unit can directly obtain and record service trigger enhancement information from the message content, such as user terminal capability data; the service trigger information collection unit can also indirectly obtain and record service trigger enhancement information from the message content, such as service trigger The information collection unit obtains the network information of the user's current visited place from the message content, and obtains the service trigger enhancement information of whether the user is currently roaming through judgment. Specifically, the user static data can be obtained and recorded from the message content in the following ways:

The first way: the user initiates registration, and the registration message carries service trigger enhancement information, such as user geographic location information data, user terminal capability data, etc., and the service trigger information collection unit collects service trigger enhancement information.

In the first method, the user initiates registration, and the user terminal or the network adds service trigger enhancement information to the registration message, and the service trigger information collection unit collects service trigger enhancement information from it. For example, when the user registration message arrives at the S-CSCF, the S-CSCF The service trigger information collection unit in the registration message obtains and records the service trigger enhancement information from the content of the registration message, such as through the Contact header field, P-Visited-Network-ID header field, P-Access-Network-Info header field, etc. in the registration message Collect, or, when the user registration message reaches the S-CSCF entity, the S-CSCF entity initiates a third-party registration carrying service trigger enhancement information to the service trigger information collection unit, and the service trigger information collection unit acquires and records the service from the content of the third-party registration message Trigger enhanced information, or, the user registration message reaches the S-CSCF entity, the S-CSCF entity initiates a third-party registration to the service trigger information collection unit, and the service trigger information collection unit initiates a subscription request message to the S-CSCF entity, and from the S-CSCF Obtain and record the business trigger enhancement information in the notification message returned by the entity.

The second way: Initiate a user information release message, the message carries service trigger enhancement information, such as user presentation information data, etc., and the service trigger information collection unit collects service trigger enhancement information.

In the second way, the user or the network can initiate an information publishing message, such as SIP PUBLISH publishing a message, to publish user information such as user presence information data, and the service trigger information collection unit obtains and records the service trigger enhancement information from the message content.

The third way: the service trigger information collection unit collects service trigger enhancement information from the user data storage unit.

In the third way, user static data such as geographic location information data and user presence information data can be stored in the user data storage unit, and the service trigger information collection unit collects service trigger enhancement information from the user data storage unit, and the service trigger information collection unit A download request can be initiated to the user data storage unit, and service trigger enhancement information can be obtained and recorded from the download request response returned from the user data storage unit. For example, the service trigger information collection unit collects user geographic location information data from HSS or CLF, Alternatively, the service trigger information collection unit may also initiate a subscription request message to the user data storage unit, and obtain and record service trigger enhancement information from the notification message returned by the user data storage unit, for example, the service trigger information collection unit subscribes to the presence server Requests the user to present informational data.

In step S201, the service trigger information collection unit may collect and obtain call-related user dynamic data (such as user call state data, etc.) service trigger enhancement information during call processing. Specifically, the service trigger information collection unit may be located in the call path of the user, process the call, and collect call state data of the user.

In step S201, the service trigger information collection unit can collect network policy trigger information unconditionally or according to the service trigger enhancement conditions corresponding to the obtained network policy trigger information, for example, the service trigger information collection unit collects "whether the user is already in the service control unit The trigger information of "service application data is configured on" and the trigger information of "whether the service control unit has been triggered" are collected.

When the service trigger information collection unit obtains the service trigger enhancement condition, because the service trigger enhancement condition can be configured in the service trigger filter rule (such as iFC), stored in the user data storage unit, and can be downloaded from the user data storage unit in the service In the trigger unit, therefore, the service trigger information collection unit can obtain the service trigger enhancement condition from the user data storage unit or the service trigger unit, and the acquisition methods can be as follows:

The first way: the user data storage unit or the service trigger unit sends the service trigger filtering rules to the service trigger information collection unit, and the service trigger information collection unit obtains the service trigger enhancement conditions therein.

In the first manner, the user data storage unit or the service trigger unit may send the information actively, or may send according to the request from the service trigger information collection unit.

In the first way, when the service trigger information collection unit obtains the service trigger enhancement condition from the obtained service trigger filtering rule, the following method can be used to obtain it:

The service trigger information collection unit parses and perceives which service trigger conditions are associated with service trigger enhancement information from the obtained service trigger filtering rules, that is, which are service trigger enhancement conditions, for example, a certain service trigger condition is set to "presence" Relatedly, the service trigger information collection unit parses and perceives that the service trigger condition is a service trigger enhancement condition, so as to obtain the service trigger enhancement condition.

Alternatively, the service trigger information collection unit acquires the service trigger enhancement condition corresponding to the special flag according to the obtained special flag in the service trigger filtering rule, such as "service trigger enhancement condition flag".

The second way: the user data storage unit or the service trigger unit sends the service trigger enhancement condition in the service trigger filter rule to the service trigger information collection unit.

Similar to the method adopted in the first method to obtain service trigger enhancement conditions, in the second method, the user data storage unit or service trigger unit can analyze and perceive which service trigger conditions are service trigger enhancement conditions in the service trigger filtering rules, Thereby sending it to the service trigger information collection unit; or, according to the special flag set in the service trigger filtering rule, such as "service trigger enhancement condition flag", the corresponding service trigger enhancement condition is sent to the service trigger information collection unit.

When the user data storage unit or the service trigger unit sends the service trigger enhancement condition, it can send it actively, or according to the request from the service trigger information collection unit.

Step S202, the service trigger information collection unit matches the obtained service trigger enhancement information with the service trigger enhancement condition, and if the matching result is successful, the service trigger information collection unit notifies the service trigger unit of the matching result.

Specifically, the service trigger information collection unit performs matching of service trigger enhancement information and service trigger enhancement conditions. If the match is successful, the service trigger information collection unit will "match result information" according to the matching result, or match the successfully matched service trigger enhancement information. The service trigger filtering rule corresponding to the condition is notified to the service trigger unit.

Wherein, the notification method adopted by the service trigger information collection unit to notify the service trigger unit is as follows:

The first way: the service trigger information collection unit downloads or updates the service trigger filter rule corresponding to the successfully matched service trigger enhancement condition, or instructs the user data storage unit to download or update the service trigger filter rule corresponding to the successfully matched service trigger enhancement condition To the business trigger unit.

In the first way, the service trigger unit may not obtain the corresponding service trigger filter rule when the user registers, and the service trigger information collection unit will save the service after matching the service trigger enhancement condition in the service trigger filter rule. Trigger the filtering rule, or instruct the user data storage unit to download the stored service triggering filtering rule to the service triggering unit. Thereafter, if the service trigger information collection unit fails to match the service trigger enhancement condition in the service trigger filtering rule, it will delete the service trigger filtering rule or instruct the user data storage unit to delete the service trigger filtering rule from the service trigger unit.

In the first way, the service trigger unit may also obtain the corresponding service trigger filter rule when the user registers, and after the service trigger information collection unit successfully matches the service trigger enhancement condition in the service trigger filter rule, it will save all The above-mentioned service trigger filtering rules, or instruct the user data storage unit to modify and download the stored service trigger filtering rules to the service trigger unit, either all or only the modified part. Afterwards, if the service trigger information collection unit fails to match the service trigger enhancement condition in the service trigger filter rule, then the saved service trigger filter rule, or instruct the user data storage unit to modify the saved service trigger filter rule again and Download to the service trigger unit. At this time, the service trigger filtering rule may include a "service trigger enhancement condition matching success flag" to identify whether the service trigger enhancement condition in the current service trigger filtering rule has been successfully matched, and the service trigger information collection unit will be based on the service trigger enhancement condition Condition matching, modify or instruct the user data storage unit to modify the corresponding "service trigger enhancement condition matching success flag". In the first way, if the service trigger unit obtains the corresponding service trigger filter rule when the user registers, after the service trigger information collection unit successfully matches the service trigger enhancement condition in the service trigger filter rule, the service trigger information collection unit It is also possible to only instruct the user data storage unit to modify the stored service trigger filtering rules, and the user data storage unit updates the service trigger unit after modification.

The second way: the service trigger information collection unit sends the corresponding "matching result information" to the service trigger unit unconditionally or according to the pre-acquisition instruction.

In the second way, the "matching result information" can generally be carried to the service trigger unit through the SIP initial request message, internal interface protocol message or Diameter protocol message. The unit indirectly sends the "matching result information" to the service trigger unit.

The service trigger information collection unit can carry more than one "matching result information" of service trigger filtering rules in one message and send it to the service trigger unit, and/or send the "matching result information" carrying more than one service trigger enhancement condition to the service trigger unit.

The "matching result information" sent by the service trigger information collection unit may include identification information of service trigger filtering rules, or may include identification information of service trigger filtering rules and service trigger enhancement conditions therein.

The pre-acquisition indication is used to indicate that the service trigger unit needs service trigger enhancement information and/or the matching result corresponding to the service trigger enhancement information, and the service trigger information collection unit sends the service trigger enhancement information and/or service trigger information to the service trigger unit according to the indication The matching result corresponding to the enhancement information, the pre-acquisition indication may be data preset on the service trigger information collection unit; or, the service trigger information collection unit parses and perceives the settings in the service trigger filter rule according to the obtained service trigger filter rule The service trigger enhancement condition is obtained, that is, the pre-acquisition indication is the service trigger enhancement condition set in the service trigger filter rule; or, the service trigger information collection unit obtains the "service trigger enhancement condition flag" set in the service trigger filter rule, As the pre-acquisition indication; or, the service trigger information collection unit uses the obtained service trigger enhancement condition as the pre-acquisition indication; or, the user data storage unit or the service trigger unit finds that the service trigger enhancement condition is set in the service trigger filter rule or "service trigger enhancement condition flag", then send the pre-acquisition instruction to the service trigger information collection unit; or, the pre-acquisition instruction is set in the service trigger filtering rule.

Similar to the "service trigger enhancement condition flag", the pre-acquisition indication may only identify that the service trigger information collection unit needs to send service trigger enhancement information to the service trigger unit, or specifically identify the type of service trigger enhancement information that needs to be sent.

If the pre-acquisition indication is also set in the service trigger filter rule, its setting is similar to the "service trigger enhancement condition flag". The following uses an iFC fragment as an example to illustrate:

<InitialFilterCriteria>

<TriggerPoint>

<ESPT>

<PreObtainingIndication>1</PreObtainingIndication>

<Presence>Meeting</Presence>

</ESPT>

</TriggerPoint>

...................................

</InitialFilterCriteria>

It can be seen that, in the above example, in the ESPT describing the service trigger enhancement condition,

"PreObtainingIndication" indicates a pre-acquisition indication, and a value of "1" indicates that the service trigger enhancement information corresponding to the service trigger enhancement condition described by the ESPT and/or the matching result corresponding to the service trigger enhancement information requires a service trigger The information collection unit sends it to the service trigger unit.

In step S202, the service trigger information collection unit may notify the service trigger unit of the matching result only when all service trigger enhancement conditions in a service trigger filtering rule are successfully matched; When a service trigger enhancement condition in the filter rule is successfully matched, the service trigger unit is notified of the matching result.

Step S203, the service trigger unit performs corresponding service trigger function processing according to the matching result from the service trigger information collection unit.

Specifically, the service triggering unit obtains "matching result information" or a service trigger filtering rule corresponding to a successfully matched service trigger enhancement condition according to the matching result notification initiated by the service trigger information collection unit, and performs the corresponding service accordingly. Trigger function processing. The service trigger unit can obtain and record the service trigger filter rules from the user data storage unit during the user registration process; it can also obtain and record the service trigger information collection unit during the notification process after the service trigger enhancement condition is successfully matched. filter rules. According to the difference in the recorded service trigger filtering rules, the service trigger unit performs corresponding service trigger function processing. There are four possible ways:

The first way: the service trigger filter rule recorded on the service trigger unit does not include the service trigger enhancement condition, but only includes the service trigger common condition. At this time, in step S203, the service triggering unit performs normal processing on the service trigger general condition in the service trigger filter rule. Then perform corresponding service triggering function processing according to the matching result, that is, if the matching is successful, call the service control unit described in the service trigger filter rule, and trigger the service to the service control unit.

The process of removing the enhanced condition of the service trigger in the service trigger filter rule can be completed by the service trigger information collection unit, the user data storage unit, or the service trigger unit.

The second way: the service trigger filtering rule recorded on the service trigger unit does not have a service trigger enhancement condition, but includes "successful matching information of the service trigger enhancement condition". At this time, in step S203, the service trigger unit combines the "matching result information" obtained from the notification issued by the service trigger information collection unit with the "service trigger enhancement condition matching success information" in the service trigger filter rule Perform matching; at the same time, perform normal processing on the common conditions of service triggering in the service trigger filter rule; and then perform corresponding service trigger function processing according to the matching result.

Similarly, the process of removing the service trigger enhancement condition from the service trigger filter rule can be completed by the service trigger information collection unit, user data storage unit, or service trigger unit.

After the service triggering unit receives the SIP initial request message carrying the "matching result information" from the service triggering information collection unit, the service triggering unit uses the content of the SIP initial request message to match the service trigger filter rule, and if the match is successful, invoke the service trigger filter rule The service control unit described in , triggers the service into the service control unit.

Taking iFC as an example, iFC describes "service trigger enhancement condition matching success information", assuming that the fragment of iFC (original iFC) signed by the user and stored in the user data storage unit is as follows:

<InitialFilterCriteria>

<TriggerPoint>

<ESPT>

<MatchingSuccessTag>pgq2487</MatchingSuccessTag>

<CallState>NoAnswer</CallState>

</ESPT>

</TriggerPoint>

...................................

</InitialFilterCriteria>

It can be seen that in the above example, an indication parameter "MatchingSuccessTag (service trigger enhanced condition matching success tag)" is given in the ESPT as "service trigger enhanced condition matching success information", the value is "pgq2487", ESPT The service trigger enhancement condition described in is the user call state (CallState), and the value of the "CallState" parameter is "NoAnswer (no answer)".

The service trigger information collection unit can obtain the value of the "service trigger enhancement condition matching success label" indication parameter while obtaining the service trigger enhancement condition. When the user call status is "no answer", the service trigger information collection unit will The value "pgq2487" of the "service trigger enhanced condition matching success label" indication parameter is used as the value of the "matching result information" parameter, and is carried in the SIP initial request message and sent to the service trigger unit.

According to the second method, it is assumed that the service trigger unit records the fragments of iFC as follows:

<InitialFilterCriteria>

<TriggerPoint>

<ESPT>

<MatchingSuccessTag>pgq2487</MatchingSuccessTag>

In the above example, in the iFC recorded on the service trigger unit, there is no service trigger enhancement condition "CallState" parameter, but there is still an indication parameter "MatchingSuccessTag (service trigger enhancement condition matching success tag)" in the ESPT. In this way, the service triggering unit uses the received matching result notification. For example, the content of the SIP initial request message matches the iFC, and the message content carries "matching result information", and combines the "matching result information" with the "MatchingSuccessTag" parameter in the iFC Take the value to match, and it is successful.

In the above example, the service trigger information collection unit can take the value "pgq2487" of the "service trigger enhanced condition matching success label" parameter as the value of the "matching result information" parameter. In addition, the service trigger information collection unit can also be "matching Result information" parameter takes a default value. For example, the default value of the "service trigger enhancement condition matching success label" parameter in the service trigger filtering rule is "1", then after the business trigger enhancement condition is successfully matched, the service trigger information collection unit Alternatively, the default value of the "matching result information" parameter may be "1".

When a user subscribes to more than one iFC that includes service trigger enhancement conditions, the value of the "service trigger enhancement condition matching success label" parameter in each iFC can be different and uniquely identified, such as "pgq2487" in the above example ; can also be the same, as the default value "1" in the above example.

The third method: the service trigger filtering rule recorded on the service trigger unit does not contain the service trigger enhancement condition, but includes a "service trigger enhancement condition matching success flag". After the service trigger information collection unit matches the service trigger enhancement condition successfully, the "service trigger enhancement condition matching success flag" in the service trigger filter rule recorded on the service trigger unit is modified to "true (true)"; According to the common business trigger conditions in the above business trigger filtering rules, normal processing is performed; and then the corresponding business trigger function processing is performed according to the matching result.

At this time, in step S202, the service trigger information collection unit or the user data storage unit modifies the "service trigger enhancement condition matching success flag" in the service trigger filter rule saved by it to "true", and then downloads it to the service trigger unit or, in step S202, the notification sent by the business trigger information collection unit through the Diameter protocol message carries "matching result information", and in step S203, the service triggering unit records it according to the obtained "matching result information" In the service trigger filter rule of the service trigger, change the "service trigger enhancement condition matching success flag" to "true".

When the "service trigger enhancement condition matching success flag" in the service trigger filter rule recorded on the service trigger unit is changed to "true", the service trigger unit judges that the service trigger enhancement condition in the service trigger filter rule has been matched successfully, and according to The corresponding service trigger function is processed for the matching result of the service trigger general condition in the service trigger filter rule.

Similarly, the process of removing the service trigger enhancement condition from the service trigger filter rule can be completed by the service trigger information collection unit, user data storage unit, or service trigger unit.

In addition, when the service trigger information collection unit fails to match the service trigger enhancement condition, the "service trigger enhancement condition matching success flag" in the service trigger filter rule recorded on the service trigger unit will be modified to "false (false)".

Taking iFC as an example, iFC describes the "service trigger enhancement condition matching success flag", assuming that the service trigger unit obtains an example of the iFC fragment when the user registers as follows:

<InitialFilterCriteria>

<TriggerPoint>

<MatchingSuccessFlag>0</MatchingSuccessFlag>

<ESPT>

<Presence>Meeting</Presence>

</ESPT>

</TriggerPoint>

...................................

</InitialFilterCriteria>

In the above example, MarchingSuccessFlag (matching success flag) is used as the "service trigger enhancement condition matching success flag", and the value is "0" to indicate "false". When the service trigger information collection unit matches the service trigger enhancement condition successfully, the service The MatchingSuccessFlag in the iFC recorded on the trigger unit is modified to "1" for "true".

The fourth way: the service trigger filtering rules recorded on the service trigger unit include service trigger enhancement conditions. At this point in step S203, because the business trigger enhancement condition is included in the recorded service trigger filter rule, and the matching work of the business trigger enhancement condition has been completed in the service trigger information collection unit, therefore, in step S203, the service trigger unit When performing matching of service trigger filtering rules, the matching processing of enhanced service trigger conditions will be ignored, and only common service trigger conditions will be matched.

When the business trigger unit ignores the matching processing of the business trigger enhancement condition, it will default that the business trigger enhancement condition has been matched successfully; or, the service trigger unit judges whether the business trigger enhancement condition has been matched successfully according to the obtained "matching result information" , at this time, in step S202, the "matching result information" sent by the service trigger information collection unit contains a corresponding service trigger filtering rule identification information, and in step S203, the service trigger unit judges according to the obtained "matching result information" The service trigger enhancement condition in the corresponding service trigger filter rule has been successfully matched, thus ignoring the matching processing of the service trigger enhancement condition; The matching result determines whether the service trigger enhancement condition has been successfully matched. If the "service trigger enhancement condition matching success information" matches the "matching result information", the service trigger unit judges that the service trigger enhancement condition has been successfully matched, thereby ignoring the business Trigger the matching processing of enhanced conditions; or, the business trigger unit judges whether the business triggered enhanced conditions have been successfully matched according to the "service triggered enhanced condition matching success flag", if the "business triggered enhanced condition matched successful flag" is "true", then The service triggering unit judges that the enhanced service trigger condition has been successfully matched, so as to ignore the matching processing of the enhanced service trigger condition.

For the above-mentioned second, third and fourth methods, there may be only one "business trigger enhanced condition matching success information" or "service trigger enhanced condition matching success flag" in a service trigger filtering rule, the information The or flag corresponds to all service trigger enhancement conditions in a service trigger filtering rule; there may also be more than one "business trigger enhancement condition matching success information" or "service trigger enhancement condition matching success flag" in a service trigger filtering rule, Each information or flag is in one-to-one correspondence with each service trigger enhancement condition in a service trigger filtering rule.

The first embodiment will be described in detail below by taking five situations as examples. Wherein, the method for collecting service trigger enhancement information by the service trigger information collection unit is as described above, and the example is not described in detail, and iFC is used as an example of service trigger filtering rules.

The first case: After the service trigger information collection unit collects the service trigger enhancement information, it performs the matching of the service trigger enhancement information and the service trigger enhancement condition. If the match is successful, the service trigger filtering rule to which the service trigger enhancement condition belongs is downloaded to the service trigger unit, after receiving a SIP INVITE message, the service triggering unit processes the corresponding service triggering function. The specific processing flow is shown in Figure 3, including:

Step 1, the service trigger unit, such as S-CSCF, receives a user's SIP REGISTER registration message.

Step 2, the service trigger information collection unit initiates a user data download request to the user data storage unit, such as the HSS.

In step 3, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In this step, the user data storage unit can download all iFCs as user data to the service trigger unit, or, the user data storage unit parses and perceives that there is a service trigger enhancement condition in the user's iFC, and then downloads to the service trigger unit that does not include the service trigger The iFC with enhanced conditions, or the user data storage unit finds that there is a "service trigger enhanced condition flag" in the user's iFC, and then downloads the iFC that does not contain the "service triggered enhanced condition flag" to the service trigger unit.

Step 4, the service triggering unit records the iFC that does not include the service trigger enhancement condition according to the received user data.

In this step, if the user data storage unit downloads all iFCs of the user to the service trigger unit, the service trigger unit analyzes and senses whether there is a service trigger enhancement condition in the user's iFC, or judges whether there is a "service trigger enhancement condition" in the user's iFC. Condition flag", the service trigger unit only records the iFC that does not contain the service trigger enhancement condition.

For example, there are three iFCs signed by the user and stored in the user data storage unit: iFC1, iFC2, and iFC3. iFC2 contains service trigger enhancement conditions, and the service trigger unit only records iFC1 and iFC3 that do not contain service trigger enhancement conditions.

Step 5: The service triggering unit initiates a third-party registration to the service triggering information collection unit, and sends a third-party registration REGISTER message.

In this step, as a preferred implementation, the service trigger information collection unit is located in the ServiceBroker network element or the SCIM application server.

Step 6: The service trigger information collection unit receives the third-party registration REGISTER message, and initiates a user data download request to the user data storage unit, such as HSS.

In this step, as a preferred implementation, the user data download request is a Diameter message, which requests "the service trigger enhancement condition contained in the iFC signed by the user".

In step 7, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In this step, the user data storage unit can download all iFCs as user data to the service trigger information collection unit, or the user data storage unit parses and perceives that there is a service trigger enhancement condition in the user's iFC, and then downloads to the service trigger information collection unit The user's service trigger enhancement condition, or the user data storage unit finds that there is a "service trigger enhancement condition flag" in the user's iFC, and then downloads the service trigger enhancement condition corresponding to the indication to the service trigger information collection unit, or the user data storage unit The unit finds that there is a "service trigger enhancement condition flag" in the user's iFC, and then downloads the iFC associated with the flag to the service trigger information collection unit, that is, the iFC where the "service trigger enhancement condition flag" is located.

In step 8, the service trigger information collection unit records the user's service trigger enhancement condition according to the received user data.

In this step, the service trigger information collection unit can completely record all iFCs signed by the user, or only record the iFC that contains the service trigger enhancement conditions, or only record the service trigger enhancement conditions in the iFC, for example, the service trigger information collection unit at least Documented the business trigger enhancement conditions in iFC2.

In step 9, the service trigger information collection unit matches the collected service trigger enhancement information with the service trigger enhancement condition, and the matching is successful.

For example, the service trigger information collection unit matches all service trigger enhancement conditions in iFC2 and matches successfully. For example, the service trigger enhancement condition describes the user presence information, such as "the user presence information is "in a meeting", then when the user presence information data collected by the service trigger information collection unit is "in a meeting", match Success, or, the business trigger enhancement condition describes the current time of the user, such as "the current time of the user is "8:00 am to 18:00 pm on weekdays"", then when the current time of the user collected by the business trigger information collection unit is " 8:00 a.m. to 18:00 p.m. on weekdays", the match is successful, or the service trigger enhancement condition describes "the service control unit is only allowed to be triggered after the user has configured the service application data on the service control unit", then when When the service trigger information collection unit collects that the user configures service application data on the service control unit, the matching is successful.

Step 10, the service trigger information collection unit instructs the user data storage unit to download the iFC corresponding to the successfully matched service trigger enhancement condition.

In this step, the service trigger information collection unit may instruct the user data storage unit to download the original iFC associated with the successfully matched service trigger enhancement condition, that is, the downloaded iFC still contains the service trigger enhancement condition, or the service trigger information The collection unit may instruct the user data storage unit to download the iFC associated with the successfully matched service trigger enhancement condition and from which the successfully matched service trigger enhancement condition has been removed.

In this step, as a preferred implementation, the instruction sent by the service trigger information collection unit to the user data storage unit at least includes the information of the successfully matched service trigger enhancement condition, or the successfully matched service trigger enhancement condition Corresponding iFC information.

For example, the service trigger information collection unit instructs the user data storage unit to download iFC2.

Step 11, the user data storage unit downloads the corresponding iFC to the service trigger unit.

In this step, the corresponding iFC may be the original iFC associated with the successfully matched service trigger enhancement condition, that is, the iFC still contains the service trigger enhancement condition, or the corresponding iFC may be the matched The iFC that is associated with the successful service trigger enhancement condition and has been matched with the successful service trigger enhancement condition is removed.

For example, the user data storage unit downloads iFC2 to the service trigger unit.

Step 12, the service triggering unit records the iFC associated with the successfully matched service trigger enhancement condition and from which the successfully matched service trigger enhancement condition is removed.

In this step, if the user data storage unit downloads the original iFC associated with the successfully matched service trigger enhancement condition, the service trigger unit parses and perceives the service trigger enhancement condition therein or according to the "service trigger enhancement condition indication", The record removes the iFC associated with the successfully matched service trigger enhancement condition.

For example, the service trigger unit records the iFC2 that removes the enhanced condition of the service trigger.

In addition, if the service trigger information collection unit has already obtained the iFC containing service trigger enhancement conditions, steps 10 and 11 can also be skipped, and the service trigger information collection unit directly downloads the corresponding iFC to the service trigger unit.

Step 13, the service trigger unit receives a SIP INVITE invitation message sent by a user.

Step 14, the service triggering unit receives the INVITE message, matches the content of the message with the iFC that does not contain the service triggering enhancement condition, and if the matching is successful, obtains the service control unit described in the iFC, such as AS.

For example, the service trigger unit matches the iFC2 without the service trigger enhancement condition, and if the match is successful, the service control unit described in the iFC2 is obtained.

Step 15, the service trigger unit invokes the service control unit and sends an INVITE message to the service control unit.

Step 16, the service trigger information collection unit finds that the service trigger enhancement information does not match the service trigger enhancement condition. For example, the service trigger information collection unit finds that a service trigger enhancement condition in iFC2 is not matched successfully, for example, the current time of the user is not "8:00 am to 18:00 pm on weekdays". Step 17, the service trigger information collection unit instructs the user data storage unit to update the iFC associated with the service trigger enhancement condition to the service trigger unit.

For example, the service trigger information collection unit instructs the user data storage unit to delete iFC2 to the service trigger unit.

Step 18, the user data storage unit updates the iFC associated with the service trigger enhancement condition to the service trigger unit.

For example, the user data storage unit deletes iFC2 from the service trigger unit.

Step 19, the service triggering unit receives the update instruction and deletes the iFC. For example, the service trigger unit deletes the recorded iFC2.

In the first case above, in step 12, the iFC2 recorded by the service trigger unit may also be the original iFC that still contains the service trigger enhancement condition, then in step 14, when the service trigger unit matches iFC2, the default service trigger enhancement The condition has been matched successfully, so the matching processing of the business trigger enhancement condition is ignored.

The second case: After the service trigger information collection unit collects the service trigger enhancement information, it performs the matching of the service trigger enhancement information and the service trigger enhancement condition. If the match is successful, the service trigger filtering rule to which the service trigger enhancement condition belongs is modified and updated to Service triggering unit, after receiving a SIP INVITE message, the service triggering unit processes the corresponding service triggering function. The specific processing flow is shown in Figure 4, including:

Step 1, the service trigger unit, such as S-CSCF, receives a user's SIP REGISTER registration message.

Step 2, the service trigger information collection unit initiates a user data download request to the user data storage unit, such as the HSS.

In step 3, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In this step, the user data storage unit may download all iFCs as user data to the service trigger unit.

For example, there are three iFCs signed by the user and stored in the user data storage unit: iFC1, iFC2, and iFC3. iFC2 contains service trigger enhancement conditions, and iFC2 contains a "service trigger enhancement condition" whose value is "false". Condition Matching Success Flag", or iFC2 may not include the "Service Trigger Enhancement Condition Matching Success Flag". The user data storage unit downloads iFC1, iFC2 and iFC3 to the service trigger unit.

Step 4, the service triggering unit records the iFC containing the service trigger enhancement condition according to the received user data.

For example, the service trigger unit records iFC1, iFC2 and iFC3.

Step 5: The service triggering unit initiates a third-party registration to the service triggering information collection unit, and sends a third-party registration REGISTER message.

In this step, as a preferred implementation, the service trigger information collection unit is located in the ServiceBroker network element or the SCIM application server.

Step 6: The service trigger information collection unit receives the third-party registration REGISTER message, and initiates a user data download request to the user data storage unit, such as HSS.

In step 7, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In step 8, the service trigger information collection unit records the user's service trigger enhancement condition according to the received user data.

For example, the service trigger information collection unit at least records the service trigger enhancement conditions in the iFC2.

In step 9, the service trigger information collection unit matches the collected service trigger enhancement information with the service trigger enhancement condition, and the matching is successful.

For example, the service trigger information collection unit matches all service trigger enhancement conditions in iFC2 and matches successfully.

Step 10, the service trigger information collection unit instructs the user data storage unit to modify the iFC corresponding to the successfully matched service trigger enhancement condition.

For example, the service trigger information collection unit instructs the user data storage unit to modify iFC2.

In this step, the instruction sent by the service trigger information collection unit to the user data storage unit includes the corresponding iFC identification information and sets a "service trigger enhancement condition matching success flag" with a value of "true" for the iFC. The iFC identification information is the identification of the user's iFC, such as the iFC priority, and is used to identify which iFC to modify.

Step 11, the user data storage unit modifies the corresponding iFC.

For example, the user data storage unit modifies iFC2, and changes the value of the "service trigger enhancement condition matching success flag" in iFC2 to "true", or adds a "service trigger enhancement condition flag" with a value of "true" in iFC2. match successful flag".

Step 12, the user data storage unit downloads the modified and updated iFC to the service trigger unit.

For example, the user data storage unit downloads the modified and updated iFC2 to the service trigger unit.

In this step, the user data storage unit can actively download the updated iFC to the service trigger unit; or, it can also initiate a notification to make the user terminal re-initiate the registration, and the service trigger unit requests the user data storage unit to download user data after receiving the registration message Thereby an updated iFC is obtained.

Step 13, the service trigger unit records the updated iFC.

For example, the service trigger unit records the updated iFC2, and the iFC2 includes a "service trigger enhanced condition matching success flag" whose value is "true".

Step 14, the service trigger unit receives a SIP INVITE invitation message sent by a user.

Step 15, the service triggering unit receives the INVITE message, matches the content of the message with the iFC containing the service trigger enhancement condition, and judges the service trigger enhancement according to the "service trigger enhancement condition matching success flag" whose value is "true" in the iFC Conditions have been matched successfully, thus ignoring the matching processing of service trigger enhancement conditions, the service trigger unit matches other service trigger general conditions in the iFC, and the match is successful, and obtains the service control unit described in the iFC, such as AS.

Step 16, the service triggering unit invokes the service control unit, and sends an INVITE message to the service control unit.

In step 17, the service trigger information collection unit finds that the service trigger enhancement information does not match the service trigger enhancement condition. For example, the service trigger information collection unit finds that a service trigger enhancement condition in the iFC2 does not match successfully.

Step 18, the service trigger information collection unit instructs the user data storage unit to modify the iFC associated with the service trigger enhancement condition.

For example, the service trigger information collection unit instructs the user data storage unit to modify iFC2.

Step 19, the user data storage unit modifies the corresponding iFC.

For example, the user data storage unit modifies iFC2, and changes the value of the "service trigger enhanced condition matching success flag" in iFC2 to "false", or deletes the "service trigger enhancement condition matching success flag" in iFC2.

Step 20, the user data storage unit downloads the modified and updated iFC to the service trigger unit.

For example, the user data storage unit downloads the modified and updated iFC2 to the service trigger unit.

Step 21, the service trigger unit records the updated iFC. For example, the service trigger unit records the updated iFC2, and there is no "service trigger enhancement condition matching success flag" whose value is "true" in the iFC2.

Case 3: After the service trigger information collection unit collects the service trigger enhancement information, it performs the matching of the service trigger enhancement information and the service trigger enhancement condition. information" and send it to the service trigger unit, and the service trigger unit receives the service trigger message and processes the corresponding service trigger function. The specific processing flow is shown in Figure 5, including:

Step 1, the service trigger unit, such as S-CSCF, receives a user's SIP REGISTER registration message.

Step 2, the service trigger information collection unit initiates a user data download request to the user data storage unit, such as the HSS.

In step 3, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In this step, the user data storage unit may download all iFCs as user data to the service trigger unit.

For example, there are three iFCs signed by the user and stored in the user data storage unit: iFC1, iFC2, and iFC3. iFC2 and iFC3 contain service trigger enhancement conditions, and the user data storage unit downloads iFC1, iFC2 and iFC3 to the service trigger unit.

iFC2 and iFC3 may or may not contain the "service trigger enhanced condition matching success information". If it is included, take iFC2 as an example, the fragment example of iFC2 is as follows:

<InitialFilterCriteria>

<TriggerPoint>

<ESPT>

<Presence>Meeting</Presence>

</ESPT>

<SPT>

<Exist>

<MatchingSuccessTag>pgq2487</MatchingSuccessTag>

</Exist>

</SPT>

</TriggerPoint>

...................................

</InitialFilterCriteria>

In the above example, the MatchingSuccessTag parameter is used as the "business trigger enhancement condition matching success information", and the value is "pgq2487". MatchingSuccessTag is set in the SPT, indicating that the parameter itself is a service trigger condition, and Exist indicates that when there are multiple trigger sources content, as long as one of the content values is "pgq2487", the service trigger condition is matched successfully.

In iFC3, the value of the parameter "Service Trigger Enhanced Condition Matching Success Information" is "mno9615". The value of the "service trigger enhancement condition matching success information" parameter in the user's iFC2 and iFC3 is different and uniquely identified.

Step 4, the service triggering unit records the iFC containing the service trigger enhancement condition according to the received user data.

For example, the service trigger unit records iFC1, iFC2 and iFC3.

Step 5: The service triggering unit initiates a third-party registration to the service triggering information collection unit, and sends a third-party registration REGISTER message.

In this step, as a preferred implementation, the service trigger information collection unit is located in the ServiceBroker network element or the SCIM application server.

Step 6: The service trigger information collection unit receives the third-party registration REGISTER message, and initiates a user data download request to the user data storage unit, such as HSS.

In step 7, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In step 8, the service trigger information collection unit records the user's service trigger enhancement condition according to the received user data.

For example, the service trigger information collection unit at least records the service trigger enhancement conditions in iFC2 and iFC3, if iFC2 and iFC3 also include the value of the parameter "service trigger enhancement condition matching success information", the service trigger information collection unit needs to further Record the parameter value of the "business trigger enhanced condition matching success information".

Step 9, the service triggering unit receives a SIP INVITE invitation message sent by a user.

Step 10, the service trigger unit sends the INVITE message to the service trigger information collection unit.

In this step, the service trigger unit can unconditionally send the received INVITE message to the service trigger information collection unit, or the service trigger unit can also match the content of the received INVITE message with iFC, successfully match with iFC1, and obtain the information described in iFC1 The service trigger information collection unit, such as ServiceBroker, sends the INVITE message to it.

Step 11, the service trigger information collection unit receives the INVITE message, judges the matching of the service trigger enhancement conditions recorded by it, generates "matching result information", and carries it in the INVITE message.

In this step, the service trigger information collection unit generates "matching result information" according to the matching situation between the recorded service trigger enhancement conditions and the collected service trigger enhancement information, which is carried in the INVITE message.

For example, if the service trigger information collection unit matches all service trigger enhancement conditions in iFC2 and iFC3 successfully, then set the value of "matching result information" to the value of the parameter "service trigger enhancement condition matching success information" contained in iFC2 and iFC3 , such as "pgq2487" and "mno9615", the example of "matching result information" carried in the INVITE message is as follows:

Record-Route: <sip:servicebroker.home 1.net; MatchingSuccessTag=pgq2487, mno9615>

In the above example, the "sip:servicebroker.home1.net" carried in the Record-Route header field is the address of the network element where the service trigger information collection unit is located, and the "MatchingSuccessTag (matching success tag)" parameter is the matching result information, including Two matching result information of iFC2 and iFC3 are obtained, namely "pgq2487" and "mno9615". Since "pgq2487" and "mno9615" uniquely identify iFC2 and iFC3 in the iFC signed by the user, they are the identification information of iFC2 and iFC3.

Alternatively, the service trigger information collection unit may also use the priority of iFC2 and iFC3 as identification information, which is carried in the "matching result information". The example of "matching result information" carried in the INVITE message is as follows:

Record-Route:<sip:servicebroker.home 1.net; MatchingSuccessiFC＝2,3>

In the above example, the "MatchingSuccess iFC (matching successful iFC)" parameter is the matching result information, which includes two matching result information of iFC2 and iFC3, that is, "2" and "3", respectively indicating the priority of iFC2 and iFC3.

Alternatively, the service trigger information collection unit may also use the priority of iFC2 and iFC3 and the value of the "service trigger enhancement condition matching success information" parameter value as identification information, and carry it in the "matching result information", the example is omitted.

Step 12, the service trigger information collection unit sends an INVITE message to the service trigger unit, and the message carries "matching result information".

Step 13, the service triggering unit receives the INVITE message, performs the matching between the content of the INVITE message and the iFC, and obtains the corresponding service control unit.

In this step, the service triggering unit processes iFCs in the order of iFC priority, such as processing iFC2, matches the content of the received INVITE message with iFC2, and the service triggering unit matches the "Success information" parameter matching, judge that the service trigger enhancement condition of iFC2 has been matched successfully, thus ignoring the matching processing of the service trigger enhancement condition in iFC2; or, the service trigger unit according to the iFC priority information contained in the "matching result information" , judging that the enhanced service triggering condition in iFC2 has been matched successfully, so the matching processing of the enhanced service triggering condition in iFC2 is ignored.

At the same time, the service trigger unit successfully matches other service trigger common conditions in iFC2, and obtains the service control unit AS1 described in iFC2.

It should be noted here that when the INVITE message carries more than one value of iFC's "service trigger enhancement condition matching success information" parameter value, such as "pgq2487" and "mno9615", when the service trigger unit performs iFC2 matching processing, According to the aforementioned Exist tag, it is judged that as long as one of the "matching result information" values matches the "service trigger enhancement condition matching success information" parameter in iFC2, it is considered that the service trigger enhancement condition of iFC2 has been matched successfully.

Step 14, the service triggering unit sends an INVITE message to the obtained corresponding service control unit (AS1).

In this step, the service trigger unit may continue to carry the "matching result information" corresponding to iFC2 in the INVITE message, or may delete the "matching result information" corresponding to iFC2, and only carry the unprocessed and iFC3 "Match result information".

Step 15, the service control unit (AS1) performs corresponding service control processing, and sends an INVITE message to the service trigger unit.

Step 16, the service triggering unit receives the INVITE message, continues to perform the matching between the content of the INVITE message and the subsequent iFC, and obtains the corresponding service control unit.

In this step, the service triggering unit continues to process subsequent iFCs according to the order of iFC priority, such as processing iFC3, and matches the content of the received INVITE message with iFC3, and the service triggering unit matches the received INVITE message content with iFC3 according to the "matching result information" and the "service trigger enhancement" in iFC3 Condition Matching Success Information" parameter match, judging that the service trigger enhancement condition of iFC3 has been matched successfully, thus ignoring the matching processing of the service trigger enhancement condition in iFC3; or, the service trigger unit prioritizes iFC according to the "matching result information" Level information, it is judged that the enhanced service trigger condition in iFC3 has been successfully matched, so the matching processing of the enhanced service trigger condition in iFC3 is ignored.

At the same time, the service triggering unit successfully matches other service triggering common conditions in iFC3, and obtains the service control unit AS2 described in iFC3.

Step 17, the service triggering unit sends an INVITE message to the obtained corresponding service control unit (AS2).

Case 4: After the service trigger information collection unit collects the service trigger enhancement information, it performs the matching of the service trigger enhancement information and the service trigger enhancement condition. If the match is successful, a service trigger message is generated and sent to the service trigger unit, and the service trigger unit receives the The service trigger message handles the corresponding service trigger function. The specific processing flow is shown in Figure 6, including:

Step 1, the service trigger unit, such as S-CSCF, receives a user's SIP REGISTER registration message.

Step 2, the service trigger information collection unit initiates a user data download request to the user data storage unit, such as the HSS.

In step 3, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In this step, the user data storage unit can download all iFCs as user data to the service trigger unit, or, the user data storage unit analyzes and perceives that there is a service trigger enhancement condition in the user's iFC, then in the iFC downloaded to the service trigger unit The service trigger enhancement condition is removed, or the user data storage unit finds that there is an "service trigger enhancement condition indication" in the user's iFC, and then removes the service trigger enhancement condition from the iFC downloaded to the service trigger unit.

For example, there are three iFCs signed by the user and stored in the user data storage unit: iFC1, iFC2, and iFC3. iFC3 contains service trigger enhancement conditions, and the user data storage unit downloads iFC1, iFC2 and iFC3 to the service trigger unit.

Step 4, the service triggering unit removes the service trigger enhancement condition from the recorded iFC according to the received user data.

In this step, if the user data storage unit downloads all iFCs of the user to the service trigger unit, the service trigger unit analyzes and senses whether there is a service trigger enhancement condition in the user's iFC, or judges whether there is a "service trigger enhancement condition" in the user's iFC. Condition flag", the service trigger unit removes the service trigger enhancement condition in the recorded iFC

For example, the service trigger unit records iFC1, iFC2, and iFC3. As a preferred implementation, the iFC3 recorded by the service trigger unit, which removes the service trigger enhancement conditions, contains a "service trigger enhancement condition matching success label", for example, the original It is described in iFC3 that the service trigger enhancement condition is "the user call status is "no answer"", then the service trigger unit records the iFC3 that removes the service trigger enhancement condition, and the iFC3 contains one and the user call status is "no answer" The "service trigger enhanced condition matching success tag" corresponding to the trigger condition, the value is "pgq2487", this tag can exist in the original iFC3, or this tag is removed from the iFC3 in the service trigger unit or user data storage unit Generated when a service triggers an enhanced condition.

Step 5: The service triggering unit initiates a third-party registration to the service triggering information collection unit, and sends a third-party registration REGISTER message.

In this step, as a preferred implementation, the service trigger information collection unit is located in the ServiceBroker network element or the SCIM application server.

Step 6: The service trigger information collection unit receives the third-party registration REGISTER message, and initiates a user data download request to the user data storage unit, such as HSS.

In step 7, the user data storage unit downloads the user data to the service trigger information collection unit in response to the download request.

In step 8, the service trigger information collection unit records the user's service trigger enhancement condition according to the received user data.

In this step, as a preferred implementation, the service trigger information collection unit also records the "service trigger enhancement condition matching success label" corresponding to the service trigger enhancement condition.

Step 9, the service trigger unit receives a SIP INVITE[1] invitation message sent to the user, and "[1]" indicates the dialog (dialog) identifier of the INVITE[1] message.

Step 10, the service trigger unit sends the INVITE[1] message to the service trigger information collection unit.

In this step, the service triggering unit can unconditionally send the received INVITE[1] message to the service triggering information collection unit, or the service triggering unit can also match the content of the received INVITE[1] message with iFC to obtain the information in iFC1. The described service trigger information collection unit, such as ServiceBroker, sends the INVITE[1] message to it.

In this step, the service trigger unit generates an original dialog identifier (Original dialog identifier), and sends it to the service trigger information collection unit through the INVITE[1] message. For a detailed description of the initial session identifier, reference may be made to relevant 3GPP standards, which will not be repeated here.

Step 11, the service trigger information collection unit uses the B2BUA (Back to Back User Agent, back-to-back user agent) mechanism to send the INVITE[2] message to the service trigger unit, and "[2]" indicates the dialogue (dialog) of the INVITE[2] message ) mark, "[2]" and "[1]" are associated as B2BUA. At this time, the service trigger information collection unit is located in the calling path of the user.

In this step, the above-mentioned initial session identifier will be carried in the INVITE[2] message. The service trigger information collection unit may continue to store the initial session identifier, for example, until the INVITE[1] message is released.

Step 12, the service triggering unit receives the INVITE[2] message, matches the content of the message with the recorded iFC, successfully matches iFC2, and obtains the service control unit described in iFC2, such as AS1.

In this step, the service triggering unit determines that the INVITE[1] message and the INVITE[2] message are B2BUA-related based on the consistency of the initial dialogue identifier in the INVITE[1] message sent by it and the received INVITE[2] message. The service triggering unit may continue to store the initial dialog identifier, for example, until the INVITE[1] message is released.

In this step, after receiving the INVITE[2] message, the service trigger unit executes the subsequent iFC after iFC1 according to the order of priority, and successfully matches iFC2 in the subsequent iFC.

Step 13, the service trigger unit invokes the service control unit, and sends an INVITE[2] message to the service control unit.

Step 14, the service trigger information collecting unit matches the collected service trigger enhancement information with the service trigger enhancement condition, and if the matching is successful, the matching result information is generated.

In this step, the service trigger information collection unit finds that all service trigger enhancement conditions in iFC3 match successfully during the signaling path maintenance process of the INVITE[1] message. For example, the service trigger enhancement condition is "the user call status is" no answer "", the service trigger information collection unit is located in the user's call path, so that when the user does not answer, the service trigger information collection unit collects that the user's call status is "no answer", that is, the service trigger enhancement information matches the service trigger enhancement condition Success, as a better implementation, use the value of the "service trigger enhancement condition matching success label" as the "matching result information".

Step 15, the service trigger information collection unit uses the B2BUA mechanism to send the INVITE[3] message to the service trigger unit, "[3]" indicates the dialog (dialog) identifier of the INVITE[3] message, "[3]" and "[ 1]" as B2BUA, and carries "matching result information" in the INVITE[3] message.

In this step, the service trigger information collection unit may send the value of "matching result information" to the service trigger unit unconditionally, or send the value of "matching result information" to the service trigger unit according to the aforementioned pre-acquisition instructions.

In this step, as a better implementation, the value of the "service trigger enhanced condition matching success tag" is used as the "matching result information" to carry the example in the SIP message as follows:

Record-Route:<sip:servicebroker.home 1.net; MatchingSuccessTag＝pgq2487>

In this step, the INVITE[3] message will carry the above-mentioned initial session identifier.

Step 16, the service triggering unit receives the INVITE[3] message, matches the content of the message with the recorded iFC, successfully matches the iFC3, and obtains the service control unit described in iFC3, such as AS2.

In this step, the service trigger unit judges that the INVITE[1] message is consistent with the INVITE[3] message by the initial dialog identifier in the received INVITE[3] message being consistent with the initial dialog identifier in the previously sent INVITE[1] message The message is B2BUA associated.

In this step, after receiving the INVITE[3] message, the service triggering unit executes the subsequent iFC after iFC1 in the order of priority, and successfully matches iFC3 in the subsequent iFC; or, executes the matching of the service enhancement trigger condition in the order of priority The previous service trigger unit matches the subsequent iFC after the last successfully matched iFC of the current call (that is, the last successfully matched iFC after the service trigger unit receives the INVITE[2] message, such as iFC2), and successfully matches the iFC3 in the subsequent iFC .

In this step, the "matching result information" carried in the INVITE[3] message is the value of the "service trigger enhancement condition matching success label" in iFC3, so that the content of the message will be the same as the "service trigger enhancement condition matching success label" in iFC3 " iFC3 matches successfully.

Step 17, the service triggering unit invokes the service control unit, and sends an INVITE[3] message to the service control unit.

Step 18, the service trigger information collection unit releases the signaling path corresponding to INVITE[2], and sends a BYE[2] goodbye message to the service trigger unit.

The service trigger information collection unit may also release the signaling path corresponding to INVITE[2] before or at the same time as sending the INVITE[3] message to the service trigger unit.

Step 19, the service triggering unit receives the BYE[2] message, and sends the BYE[2] message to AS1 according to the signaling path.

Afterwards, if there are other devices located behind AS1 in the signaling path caused by the INVITE[2] message, the service trigger unit will also release these devices one by one. The fifth case: the service trigger information collection unit and a service trigger unit are located on the same network element, and after the service trigger information collection unit collects the service trigger enhancement information, it performs matching of the service trigger enhancement information and the service trigger enhancement condition, and the matching is successful. Generate an internal interface protocol message carrying "matching result information" to notify the service triggering unit, and the service triggering unit receives the "matching result information" and processes the corresponding service triggering function. The specific processing flow is shown in Figure 7, including:

Step 1, the service trigger unit 1, such as S-CSCF, receives a user's SIP REGISTER registration message, and after corresponding processing, initiates a third-party registration to the service trigger information collection unit, and sends a third-party registration REGISTER message.

In this step, as a preferred implementation, there are two service trigger units, the S-CSCF is the service trigger unit 1, and the service trigger unit 2 and the service trigger information collection unit are located in the same network element, such as the ServiceBroker network element.

Step 2, ServiceBroker receives the third-party registration REGISTER message, and initiates a user data download request to the user data storage unit, such as HSS.

In step 3, the user data storage unit downloads the user data from the ServiceBroker in response to the download request.

Step 4, ServiceBroker records the user's service trigger enhancement condition according to the received user data.

For example, there are three iFCs signed by the user and stored in the user data storage unit: iFC1, iFC2, and iFC3. iFC3 contains service trigger enhancement conditions, and the user data storage unit downloads iFC1, iFC2, and iFC3 to ServiceBroker. The service trigger unit 2 The iFC3 is obtained, and the service trigger information collection unit obtains the service trigger enhancement condition in the iFC3.

Step 5, S-CSCF receives a SIP INVITE[1] invitation message sent to the user, "[1]" indicates the dialog (dialog) identifier of the INVITE[1] message.

Step 6: S-CSCF sends the INVITE[1] message to ServiceBroker.

In this step, the S-CSCF can unconditionally send the received INVITE[1] message to ServiceBroker, or, the S-CSCF can also match the content of the received INVITE[1] message with iFC to obtain the ServiceBroker described in iFC1, Then send the INVITE[1] message to it.

In this step, the S-CSCF generates an original dialog identifier (Original dialog identifier), and sends it to the ServiceBroker through the INVITE[1] message.

Step 7, ServiceBroker uses the B2BUA (Back to Back UserAgent, back-to-back user agent) mechanism to send the INVITE[2] message to the S-CSCF, "[2]" indicates the dialog (dialog) identifier of the INVITE[2] message, "[ 2]" and "[1]" are associated as B2BUA. At this point, ServiceBroker is in the user's call path.

In this step, the above-mentioned initial session identifier will be carried in the INVITE[2] message. ServiceBroker can continue to save the initial dialog identifier, such as saving until the INVITE[1] message is released.

Step 8: S-CSCF receives the INVITE[2] message, matches the content of the message with the recorded iFC, and successfully matches iFC2, and obtains the service control unit described in iFC2, such as AS1.

In this step, the S-CSCF judges that the INVITE[1] message and the INVITE[2] message are B2BUA associations based on the consistency of the initial session identifier in the INVITE[1] message sent by it and the received INVITE[2] message. The S-CSCF may continue to store the initial session identifier, for example, until the INVITE[1] message is released.

In this step, after receiving the INVITE[2] message, the S-CSCF executes the subsequent iFCs after iFC1 in order of priority, and matches iFC2 in the subsequent iFCs successfully.

In step 9, the S-CSCF invokes the service control unit and sends an INVITE[2] message to the service control unit.

Step 10, the service trigger information collecting unit matches the collected service trigger enhancement information with the service trigger enhancement condition, and if the matching is successful, the matching result information is generated.

In this step, the service trigger information collection unit finds that all service trigger enhancement conditions in iFC3 match successfully during the signaling path maintenance process of the INVITE[1] message. For example, the service trigger enhancement condition is "the user call status is" no answer "", the service trigger information collection unit is located in the user's call path, so that when the user does not answer, the service trigger information collection unit collects that the user's call status is "no answer", that is, the service trigger enhancement information matches the service trigger enhancement condition success.

The service trigger information collection unit sends "matching result information" to the service trigger unit 2 through an internal interface protocol message, and the "matching result information" carries the identification information of iFC3.

Step 11, the service trigger unit 2 receives the "matching result information", judges that the service trigger enhancement condition in iFC3 has been matched successfully, matches other service trigger general conditions in iFC3, and the match is successful, and obtains the corresponding service control unit, such as AS2 .

In this step, the service trigger unit 2 judges that the service trigger enhancement condition in iFC3 has been successfully matched according to the identification information of iFC3 in the "matching result information"; the service trigger unit 2 uses the previously received INVITE[1] message content or The subsequent message content of the INVITE[1] message matches other common conditions for triggering services in iFC3, and if the matching is successful, the corresponding service control unit AS2 is obtained.

Step 12, ServiceBroker releases the signaling path corresponding to INVITE[2], and sends BYE[2] goodbye message to S-CSCF.

Step 13, the S-CSCF receives the BYE[2] message, and sends the BYE[2] message to AS1 according to the signaling path.

Afterwards, if there are other devices located behind AS1 in the signaling path caused by the INVITE[2] message, the S-CSCF will also release these devices one by one.

Step 14, ServiceBroker uses the B2BUA mechanism to send an INVITE[3] message to the S-CSCF, "[3]" indicates the dialog (dialog) identifier of the INVITE[3] message, and "[3]" and "[1]" serve as B2BUA is associated, and AS2 routing information is carried in the INVITE[3] message.

An example of an INVITE[3] message is as follows:

Route:<sip:scscf.home 1.net;lr>;dia-id=7574839201

Route:<sip:as2.home 1.net;lr>

In the above example, "sip:scscf.home1.net" in the first Route header field is the S-CSCF routing information, and "sip:as2.home1.net" in the second Route header field is the AS2 routing information. "7574839201" is the above-mentioned initial session identifier.

If in step 10 and step 11, the business trigger information collection unit finds that all business trigger enhancement conditions in more than one iFC are successfully matched, the business trigger unit 2 matches other business trigger common conditions in these iFCs successfully, and obtains a corresponding For the above service control units, in this step, the INVITE[3] message may carry more than one service control unit routing information.

Step 15, the S-CSCF receives the INVITE[3] message, and sends the INVITE[3] message to AS2 according to the routing information of AS2 carried in the message.

In this step, the S-CSCF judges that the INVITE[1] message is consistent with the INVITE[3] message through the fact that the initial session identifier in the received INVITE[3] message is consistent with the initial session identifier in the previously sent INVITE[1] message. The message is B2BUA associated.

It can be seen that in the first case to the fifth case, the matching of the service trigger enhancement condition and the service trigger enhancement information is performed on the service trigger information collection unit, the difference is that the way of notifying the service trigger unit of the matching result is different, and The difference between their implementations lies in the different attributes of the service trigger enhancement conditions. The service trigger enhancement conditions in the first to third cases are user static data or network policy trigger information that have nothing to do with calls, while the fourth case and The service trigger enhancement condition in the fifth case is call-related user dynamic data (on this basis, it is also allowed to further include call-related user static data in the service trigger filter rule that contains call-related user dynamic data or network policy trigger information), in this way, further, the network can adopt different processes according to the attributes of service trigger enhancement conditions, for example, it can further distinguish and describe service trigger enhancement that is irrelevant to calls and call-related in iFC conditions, and the enhanced conditions can also be triggered by the network analysis service to perceive its attributes.

The second embodiment of the present invention provides a service trigger method, wherein the service trigger unit acquires service trigger filter rules according to the existing process, and the service trigger filter rules include service trigger enhancement conditions, and this part will not be described here content. The flow process of the second embodiment is shown in Figure 8, including:

In step S301, the service trigger information collection unit collects service trigger enhancement information.

The process of collecting service trigger enhancement information by the service trigger information collecting unit is the same as the relevant description in the first embodiment, and will not be described in detail here.

In step S302, the service trigger unit obtains service trigger enhancement information from the service trigger information collection unit.

There are several ways to obtain it:

The first way: the service trigger unit requests service trigger enhancement information from the service trigger information collection unit.

In the first manner, the service trigger unit may request service trigger enhancement information from the service trigger information collection unit through internal interface protocol messages or SIP messages. For example, after receiving a SIP initial request message, the service trigger unit sends the SIP initial request message to the service trigger information collection unit, and the message carries a request indication for service trigger enhancement information, and the service trigger information collection unit indicates according to the request. The service trigger enhancement information is carried in the returned SIP message.

After receiving a SIP initial request message, the service trigger unit can unconditionally request service trigger enhancement information to the service trigger information collection unit; The trigger information collection unit requests service trigger enhancement information; or, the service trigger unit requests service trigger enhancement information from the service trigger information collection unit according to the "service trigger enhancement condition flag" or "pre-acquisition indication" in the service trigger filtering rule.

The second way: the service trigger information collection unit actively sends service trigger enhancement information to the service trigger unit.

In the second manner, the service triggering information collection unit may actively send a request for service triggering enhancement information to the service triggering unit unconditionally or according to a pre-acquisition instruction.

For example, after the service trigger unit receives a SIP initial request message, it sends the SIP initial request message to the service trigger information collection unit. The message does not carry a request for service trigger enhancement information, and the service trigger information collection unit unconditionally or according to The pre-acquisition instruction actively sends service trigger enhancement information to the service trigger unit.

The description of the pre-acquisition instruction is the same as the relevant description in the first embodiment, and will not be described in detail here.

Step S303, the service triggering unit matches the service trigger enhancement information with the service trigger filter rule, and processes the corresponding service trigger function according to the matching result.

Specifically, the service trigger unit matches the service trigger enhancement information and the service trigger enhancement condition in the service trigger filter rule successfully, and other service trigger conditions in the service trigger filter rule executed by the service trigger unit are also successfully matched, then Invoke the service control unit described in the service trigger filter rule.

The first embodiment will be described in detail below by taking two cases as examples. Wherein, the method for collecting service trigger enhancement information by the service trigger information collection unit is as described above, and the example is not described in detail, and iFC is used as an example of service trigger filtering rules.

Case 1: The service trigger unit receives a SIP INVITE message, requests the service trigger information collection unit to obtain service trigger enhancement information, and the service trigger unit matches the service trigger enhancement information with the service trigger enhancement condition, and processes the corresponding service trigger function . Its specific implementation process is shown in Figure 9, including:

Step 1, the service triggering unit, such as S-CSCF, receives a SIP INVITE invitation message.

Step 2, the service trigger unit requests service trigger enhancement information from the service trigger information collection unit.

In this step, as a preferred implementation, the service trigger information collection unit is located in the S-CSCF, and the request sent by the service trigger unit to the service trigger information collection unit is an internal interface protocol message.

In this step, after receiving the INVITE message, the service triggering unit may unconditionally request the service triggering enhancement information from the service triggering information collection unit, or, after the service triggering unit analyzes and perceives that there is a service triggering enhancement condition in the iFC, if it finds that there is Describe the service trigger condition of the user terminal capability, then request service trigger enhancement information to the service trigger information collection unit, or, after the service trigger unit finds that there is a "service trigger enhancement condition flag" in the iFC, request service trigger enhancement to the service trigger information collection unit information.

In this step, the request sent by the service trigger unit may only indicate that the service trigger enhancement information is requested, or may specifically indicate which one or several or which type or types of service trigger enhancement information is requested.

In this step, if the current service user is a multi-terminal registered user, and the service trigger enhancement information is associated with the terminal, for example, the service trigger enhancement information is the user terminal capability, and the user has more than one registered terminal, that is, the service trigger information collection unit exists There are more than one user terminal capabilities of the user, at this time, the service trigger unit can request all the user terminal capabilities of the user, or only request the required user terminal capabilities, that is, the service trigger unit can request the user terminal capabilities of the specified terminal, The request sent by the service trigger unit carries specified terminal information, and the specified terminal information comes from the content of the INVITE message, which can be the unique identifier of the terminal (such as contact address, GRUU, etc.), or caller preferences (Caller Preferences) wait.

In step 3, the service trigger information collection unit returns service trigger enhancement information.

Step 4, the service triggering unit uses the received INVITE message content and service triggering enhancement information to match the iFC, and the matching is successful, and obtains the service control unit described in the iFC, such as an AS.

In this step, if the current service user is a multi-terminal registered user, and the service trigger enhancement information is associated with the terminal, for example, when the service trigger enhancement information is the user terminal capability, if the service trigger unit has obtained the user terminal capability of the specified terminal, then Use the user terminal capabilities of the specified terminal and the content of the INVITE message to match iFC; if the service trigger unit obtains the user terminal capabilities of all registered terminals of the user, the service trigger unit can sequentially use the user terminal capabilities of one of the terminals and the INVITE message The content matching iFC, or, the service triggering unit selects the user terminal capability of one of the terminals according to the specified terminal information and the content matching iFC of the INVITE message.

Step 5, the service trigger unit invokes the service control unit and sends an INVITE message to the service control unit.

The second case: the service trigger unit receives a SIP INVITE message, sends the message to the service trigger information collection unit, and the service trigger information collection unit attaches the service trigger enhancement information to the SIP INVITE message according to the pre-acquisition instruction and returns it to the service trigger The service trigger unit matches the service trigger enhancement information with the service trigger enhancement condition, and processes the corresponding service trigger function. The specific implementation process is shown in Figure 10, including:

Step 1, the service trigger unit, such as S-CSCF, receives a user's SIP REGISTER registration message.

Step 2: The service trigger unit initiates third-party registration to the service trigger information collection unit, and sends a third-party registration REGISTER message.

In this step, as a preferred implementation, the service trigger information collection unit is located in the ServiceBroker network element or the SCIM application server.

Step 3, the service trigger information collection unit receives the third-party registration REGISTER message, and initiates a user data download request to the user data storage unit, such as HSS.

In this step, as a preferred implementation, the user data download request is a Diameter message, which requests "whether the service trigger enhancement condition is included in the iFC signed by the user", and specifically may be a request for "service trigger enhancement condition indication" Or "prefetch indication".

Step 4, the user data storage unit responds to the download request, and downloads the user data to the service trigger information collection unit.

In this step, as a preferred implementation, the user data download is a Diameter message. If the iFC signed by the user contains the information of the service trigger enhancement condition, then the message carries "the service trigger enhancement condition is included in the iFC signed by the user." ", which may specifically be "service trigger enhancement condition indication" or "pre-acquisition indication".

Step 5, the service trigger information collection unit records the pre-acquisition instruction according to the received user data.

In this step, the service trigger information collection unit processes the iFC as user data, and after analyzing and sensing the service trigger enhancement condition in the iFC, if it finds that there is a service trigger condition describing the information presented by the user, then generate and record the pre-acquisition instruction, or, The service trigger information collection unit finds that there is a "service trigger enhancement condition flag" in the iFC, then generates and records the pre-acquisition indication, or, the service trigger information collection unit finds that there is a "pre-acquisition indication" in the iFC, then records the pre-acquisition indication, or, The "service trigger enhancement condition flag" is sent directly from the user data storage unit to the service trigger information collection unit as user data, and the service trigger information collection unit generates and records the pre-acquisition instruction accordingly, or the "pre-acquisition instruction" is used as user data, Send directly from the user data storage unit to the service trigger information collection unit, or the service trigger information collection unit directly uses the obtained "service trigger enhancement condition flag" as a pre-acquisition instruction.

Step 6, the service trigger unit receives a SIP INVITE invitation message sent by a user.

Step 7, the service trigger unit sends the INVITE message to the service trigger information collection unit.

In this step, the service trigger unit can unconditionally send the received INVITE message to the service trigger information collection unit, or the service trigger unit can also match the content of the received INVITE message with iFC to obtain the service trigger information collection described in iFC A unit, such as ServiceBroker, sends the INVITE message to it.

Step 8: The service trigger information collection unit receives the INVITE message, and adds the service trigger enhancement information to the message to be sent to the service trigger unit according to the user's "pre-acquisition instruction" or "service trigger enhancement condition flag".

In this step, if the "pre-acquisition indication" or "service trigger enhancement condition flag" does not indicate which or what kind of service trigger enhancement information is associated with, the service trigger information collection unit will collect all the service trigger enhancement information of the user Attached to the message to be sent to the service trigger unit, or if the pre-acquisition indication or the service trigger enhancement condition flag specifically indicates which or which service trigger enhancement information is associated, the service trigger information collection unit will correspond to the service trigger Enhanced information is attached to the message to be sent to the service trigger unit.

The way in which service-triggered enhancement information such as user presence information data, user geographic location information data, user terminal capability data, and user preference setting data is carried in SIP messages can already be supported by existing technologies, and will not be repeated here.

Step 9: The service trigger information collection unit sends an INVITE message carrying service trigger enhancement information to the service trigger unit.

Step 10, the service triggering unit receives the INVITE message, matches the content of the message with the iFC, and if the matching is successful, obtains the service control unit described in the iFC, such as AS.

Step 11, the service triggering unit invokes the service control unit, and sends an INVITE message to the service control unit.

In the first case and the second case, the matching of service trigger enhancement conditions and service trigger enhancement information is carried out on the service trigger unit. The difference lies in the different attributes of the service trigger enhancement information. In the first case, the service trigger information collection unit and the service trigger unit are located in the same network element S-CSCF, that is, the service trigger enhancement information itself can be collected by the S-CSCF. For example, when a user registers, the S-CSCF collects service trigger enhancement information directly or indirectly from the content of the registration message. In the second case, the service trigger information collection unit and the service trigger unit are located in different network elements, and the service trigger enhancement information cannot Collected by the S-CSCF, such as user presence information data, etc. In this way, the network can adopt different processes according to the attributes of service trigger enhancement conditions. For example, the service trigger enhancement conditions that S-CSCF can collect and cannot be collected can be further differentiated and described in iFC, and the service triggers can also be analyzed by the network. Conditions are enhanced to perceive their properties.
