Description

 System, device and method for processing a service in a packet domain network

 The present invention relates to the field of packet domain networks, and in particular, to a system, apparatus and method for processing services in a packet domain network.

Background technique

 The packet domain network has become the research focus of the next generation network because it uses the technology of separation of service management, session control and bearer access. The Internet Protocol Multimedia Subsystem (IMS) network is a packet domain network. IMS is an IP multimedia subsystem defined by the 3GPP, 3rd Generation Partnership Project (3GPP). The 3G, 3rd Generation mobile network implements packet voice and packet data, providing a unified multimedia service and application target network. The IMS network uses the IP packet domain as the bearer channel for control signaling and media transmission, and uses the Session Initiation Protocol (SIP) as the call control signaling to implement the three functions of service management, session control and bearer access. Separation. Among them, SIP is an application layer control protocol for establishing, changing and terminating multimedia sessions or calls. These multimedia sessions include multimedia conferences, distance learning, and Internet telephony. At present, some international standards organizations, such as the International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) and the European Telecommunications Standards Institute (ETSI), also adopt IMS as their own definition. The core network of a generation of networks.

 In a packet domain network, since session control and service management are separate, the packet domain network must provide necessary control for service management to ensure smooth application of services. In a packet domain network, services can be classified into user subscription services and non-user subscription services. Among them, the provision of user contracted business includes three basic steps:

First, define a possible set of business or business. Secondly, when the user subscribes to the service or tampers with the service subscription relationship, the user-specific service data is created in the form of an initial filter rule (iFC, Initial Filter Criteria).

 The iFC is a service-triggered filtering rule. Specifically, the iFC includes a user-signed service triggering condition and an application server (AS, Application Server) corresponding to the service, and the service triggering condition is triggered by a service point trigger (SPT, Service). Point Trigger), the content of the SPT includes: a request-uniform resource identifier (Request-URI), which identifies a resource pointed to by the SIP initial request message; a SIP method (Method), which is used to indicate the type of the SIP initial request message; A header (Header), which contains information related to the SIP initial request message, may be any SIP header field and header content therein; a Session Case, having three possible values, ie, starting, terminating, or terminating unregistered Session Description (Session Description), which indicates the content of the Session Description Protocol (SDP) field in the SIP method.

 Finally, when the IMS network element service-call session control function (S-CSCF, Serving-Call Session Control Function) receives the SIP initial request message, performs iFC according to the current session situation and the received SIP initial request message, and determines The AS corresponding to the current session scenario and the SIP initial request message, and the received SIP initial request message is delivered to the determined AS.

In the packet domain network, there is also a non-user subscription service that can be provided. This is a type of network public service, and the user does not need to sign the service with the operator to use the service. The non-user subscription service may be a system service provided by the network, such as a black and white list service, and each call of each user needs to be filtered, such as a 17951 telephone service. Or, the user who provides the service is contracted first, so that other users can use the non-user-signed service, such as the 800 free service, and the user who announces the 800-free number (such as the enterprise) to apply for the contract for 800 free of charge. Business, to get 800 free numbers, and users who call 800 free numbers do not need to sign up with the operator before use; like the Universal Personal Telecommunications service, users who announce the number one number apply to the operator. Signing the No. 1 service to obtain the No. 1 number, and the user calling the No. 1 number does not need to use it before use. To sign a contract with the operator. When using a non-user subscription service, the user can indicate the type of non-user subscription service used in the application, such as "17951", "800", and the like.

 There are two ways to provide non-user contracted services, which are described separately below.

 The first method is to enable the user to have an iFC that is not a subscriber subscription service, that is, to correspond to each user who may use the non-subscription service, and use the non-user subscription service as the user subscription service of the user, set the iFC, and process according to the iFC. For example: the black and white list service provided by the packet domain network needs to be filtered for each call of each user, so that each user can be set with an iFC pointing to the AS providing the black and white list service, when the S-CSCF receives the user initiated When the SIP initial request message is executed, the configured iFC enables the user-initiated SIP initial request message to be processed to the AS that provides the black-and-white list service to perform filtering of the black-and-white list service for the SIP initial request message.

 When the packet domain network handles the non-user subscription service in the first way, it has the following disadvantages: When the packet domain network provides a new non-user subscription service, it must be synchronized to all users who may implement this non-user subscription service. The iFC describing the non-user subscription service has disadvantages such as inefficiency and poor scalability due to the large number of users in the packet domain network and the unpredictable types of non-user subscription services.

In the second method, the non-user subscription service is described by using a public service identifier (PS I , Publ ic Serv ice Ident ty ), and the PSI indicates the service identifier provided by the packet domain network. When receiving the SIP initial request message initiated by the user, the PS is performed. The I route to the AS that handles the non-user subscription service, and processes the SIP initial request message. The specific process of calling non-user subscription services through PSI can be found in the related 3GPP standards. The user's user subscription service and the user's non-contracted service are processed to provide corresponding services for the user. However, in some cases, there may be a problem of service interaction between the user subscription service and the non-user subscription service, for example, the user subscribes to a call. When the user dials 800 free services, it is obvious that the call restriction service is not triggered at this time. At present, the service interaction between the user subscription service and the non-user subscription service can be solved by the following scheme. : First, in use The iFC of the subscriber subscription service describes the interaction relationship between the subscriber subscription service and the non-user subscription service. Second, the interaction relationship between the subscriber subscription service and the non-user subscription service is described in the AS providing the subscriber subscription service.

 The above two solutions must predetermine the relationship between the non-user subscription service and the subscriber subscription service, such as 800 free service and call restriction service, so that when the packet domain network sets up a new non-user subscription service, it must be synchronized at all The non-user subscription service has a relationship between the user-signed service iFC or the AS that provides the user subscription service, and a new non-user subscription service attribute description is added to solve the service interaction between the user-signed service and the non-user-signed service. The management of non-user subscription services is inefficient, and the expansion of non-user subscription services is more difficult. Summary of the invention

 The embodiment of the invention provides a system for processing services in a packet domain network, which can centrally process non-user subscription services to improve management efficiency of non-user subscription services. The embodiment of the present invention further provides an apparatus for processing a service in a packet domain network, where the apparatus can centrally process non-user subscription services to improve management efficiency of non-user subscription services.

 FIG. 3 is a flowchart of a method for processing a service in a packet domain network according to an embodiment of the present invention, where a centralized service processing unit is set in a packet domain network, and the specific steps are:

Step 301: The service triggering unit processes the current communication request, and when the service trigger condition is met, The centralized service processing unit sends a service trigger request.

 In this step, the service triggering unit may send a service trigger request message, such as a SIP initial request message, or an internal interface message, to the centralized service processing unit after unconditionally or after matching the iFC that describes the centralized service processing unit.

 That is, the service triggering unit may send a service trigger request, such as a SIP initial request message, or an internal interface message, to the centralized service processing unit unconditionally or according to the communication request content or the like. For example, the service triggering unit may send a service trigger request to the centralized service processing unit unconditionally before executing the iFC; or, the service triggering unit may unconditionally send a service trigger request to the centralized service processing unit after executing the iFC; or, the service The triggering unit performs the matching of the communication request content and the iFC, and describes that the iFC of the centralized service processing unit is successfully matched, and sends a service trigger request to the centralized service processing unit; or the service triggering unit according to the non-user subscription service indication in the communication request content, A service trigger request is sent to the centralized service processing unit, the indication indicating that the communication request uses a non-user subscription service.

 Step 302: The centralized service processing unit processes the service trigger request.

 In this step, the centralized service processing unit can process the set non-user subscription service logic function, and send a service trigger response to the service trigger unit.

 For example, the black and white list service logic is set in the centralized service processing unit. After receiving the service trigger request, the centralized service processing unit performs the filtering of the black and white list service for the service trigger request, and completes the business logic control function of the black and white list.

 For example, the logical control of the business interaction relationship between the 800 free service and the user subscription service is set in the centralized service processing unit. When the centralized service processing unit receives the service trigger request, the logical control function of the 800 free service business interaction relationship is generated. The service interaction indication is sent to the service triggering unit in the service trigger request response.

For example, the centralized service processing unit routes the service trigger request to the service control unit according to the service identifier of the non-user subscription service, and the service control unit provides the non-user subscription service logic control function. For example, the centralized service processing unit will service according to the service identifier in the Reques t-URI. The trigger request is routed to the service control unit, and the service control unit provides the non-user subscription service logic control function. Alternatively, the centralized service processing unit processes the received service trigger request according to the service configuration of the service configuration storage unit, and triggers the call of the service control unit. The non-user subscription service logic control function is provided by the service control unit, and the corresponding relationship between the service identifier and the service control unit is described in the service configuration.

 For example, the centralized service processing unit processes the service identifier of the non-user subscription service, and performs processing such as deleting, hiding, transferring, restoring, and separating. For example, the service trigger request is a SIP message, and the Reques t-URI includes a service identifier and a session destination identifier of the non-user subscription service, such as a 17951 + called number, and the centralized service processing unit sets the service identifier (such as 17951) from Reques. If the t-URI is deleted, the service identifier may be further transferred to the header field or the message body of the SIP message, or the previously deleted service identifier may be restored to the Reques t-URI, or may be located in the SIP. The service identifier in the header field or the message body of the message is transferred to the Reques t-URI. When the service identifier is transferred between the Reques t-URI and the header field or the message body, the original format may be transferred, or the format may be transferred.

 That is to say, the centralized service processing unit may provide all or part of the business logic control function for the service trigger request, or may be provided by the centralized service processing unit to provide all or part of the service control unit triggered by the processing of the service trigger request. Business logic control features.

 In this step, the centralized service processing unit performs the following two methods for processing the service trigger request according to the service configuration of the service configuration storage unit:

 The first processing method: the centralized service processing unit performs the processing of the service trigger request, requests the service configuration storage unit to obtain the service control unit described in the service configuration corresponding to the service trigger request content, and the centralized service processing unit triggers the service determined by the call. control unit;

The second processing method is: the centralized service processing unit performs processing of the service trigger request, performs matching of the service trigger request content and the service configuration from the service configuration storage unit, and the matching is successful, and the service control unit described in the service configuration is obtained, and the centralized The service processing unit triggers the call of the determined service control unit according to the service control unit information. The process of obtaining the service configuration from the service configuration storage unit by the centralized service processing unit may be direct or indirect. The indirect process refers to: the service triggering unit first obtains the service configuration from the service configuration storage unit, and then the centralized service processing unit and the service. The trigger unit gets the service configuration.

 The service configuration of the non-user subscription service obtained by the centralized service processing unit may be a service triggering filtering rule similar to the iFC, where the service triggering condition is described, for example, the called number includes 800, and the corresponding service control unit information is described. . Further, an "always execute" flag may be used in the service configuration to instruct the centralized service processing unit to "always" perform a match with the service configuration after receiving the service trigger request. In this way, after receiving the service trigger request, the centralized service processing unit can unconditionally match all the acquired service configurations in order, or can only match the service configuration with the "always execute" flag.

 In a practical application, the centralized service processing unit may directly perform address resolution on the called number carried in the service trigger request, for example, querying a Domain Name System (DNS) server to obtain a corresponding service control unit. The centralized service processing unit triggers the call to determine the determined service control unit.

 In the actual application, after the business interaction relationship logic of the non-user subscription service and the user subscription service set in the centralized service processing unit is executed, a centralized service processing unit generates a service interaction indication, or the centralized service processing unit triggers the call. After the service interaction logic of the non-user subscription service and the user subscription service in the service control unit is executed, the service control unit generates a service interaction indication, and the service interaction indication is carried in the message and transmitted to the service trigger unit, and the service triggers The unit or other network element determines, according to the service interaction indication, whether other services related to the service trigger request need to be executed.

 In the embodiment of the present invention, the service interaction indication can be described in two ways:

The first description manner: The service interaction indication may be a service identifier, which is used to identify the type or attribute that has performed the non-user subscription service. This is an implicit indication of business interaction. For example, when the non-user subscription service is 800 free services, it can be identified as 800, or a free call, or a call that exceeds the call restriction, etc., when a network entity in a packet domain network, such as a service trigger unit, a service control list After receiving the communication request carrying the service identifier, the UE determines whether other services related to the 800 free service are allowed to be executed.

 The second description mode is as follows: The service compatibility identifier is used to identify the service interaction compatibility information of the non-user subscription service and the user subscription service. This is an explicit service interaction indication. For example, the service compatibility identifier may be "allow or prohibit other services related to non-user subscription services being executed" or "service compatibility level" and the like. The service compatibility level may be preset data, and corresponds to a non-user subscription service, for example, data in a service configuration of a non-user subscription service, in a network entity in a packet domain network, such as a service trigger unit, Receiving the "service compatibility level carried by the service trigger response, and correlating with the "service compatibility level" of other services to determine whether other services are allowed to be invoked. Embodiment 1:

 4, the user initiates 800 free service call, that is, sends a SIP access (INVITE) message carrying 800 free call number to the service trigger unit, the service trigger unit forwards the message to the centralized service processing unit, and the centralized service processing unit performs the set 800 free. After the call and the service interaction logic function of the user subscription service, the SIP INVITE message is sent to the service triggering unit, where the message carries the service interaction indication, and the service triggering unit routes the message to the 800 service control unit, and the 800 service control unit Provide 800 free call service to users. The specific process is shown in Figure 4.

 FIG. 4 is a flowchart of a method for processing a service in a packet domain network according to an embodiment of the present invention, where the network entity includes a service triggering unit, a centralized service processing unit, and an 800 service control unit.

 Step 401: The service triggering unit, for example, the S-CSCF currently registered by the user, receives the SIP INVITE message sent by the user and carrying the 800 free calling number.

Step 402: The service triggering unit sends the SIP INVITE message to the centralized service processing unit. In this step, the centralized service processing unit can be located in Service Broker or SCIM. In this step, the service triggering unit may unconditionally send the SIP INVITE message to the centralized service processing unit, or the service triggering unit may match the iFC that describes the 800 free call service. Obtain a corresponding centralized service processing unit, and send the SIP INVITE message to the centralized service processing unit.

 Step 403: After receiving the SIP INVITE message, the centralized service processing unit performs the analysis of the called number, determines that the call is 800 free calls according to the 800 free call number carried in the SIP INVITE message, and performs the set 800 free call and the user subscription service. After the business interaction relationship logic function, a corresponding service interaction indication is generated.

 Step 404: The centralized service processing unit sends a SIP INVITE message to the service triggering unit, where the message carries a service interaction indication.

 In this step, the centralized service processing unit may carry a service interaction indication by using a caller preference information segment (Ca l ler Perfernces) in the SIP INVITE message, where the service interaction indication may be a service identifier, and the centralized service processing unit is The analysis of the called number sent by the user, that is, according to the 800 free call number carried in the SIP INVITE message in step 303, the user's preference is determined as "hoping to make a 800 free call", so the centralized service processing unit is in Ca ller Perfernces. The service tag indication can be identified by setting a corresponding feature tag. The feature tag can use existing feature tags, such as "actor" or "pr ior i ty" feature tags, or extend the existing feature tag parameter values, and also extend new feature tags, ^ port "free ( Free ),,, "Information, monthly service (informa t ion), or "call center, (ca l lcenter),, etc.

 Step 405: After receiving the SIP INVITE message carrying the service interaction indication, the service triggering unit performs a session control process of 800 free calls. In this step, the session control process for performing the 800 free call may be the execution of the set iFC, and one of the service trigger conditions described in the iFC is: "The message does not include the calling preference information segment feature tag indicating the service interaction indication. In this way, the SIP INVITE message received by the service triggering unit and the iFC match are unsuccessful, and the service control unit of the iFC, such as the AS of the call restriction service, will not be triggered.

In this step, the service control unit performs subsequent session control processing on the SIP INVITE message, that is, the SIP INVITE message performs PSI routing according to the prior art, and performs PSI address resolution. Trigger 800 service control unit.

 Step 406: The service triggering unit sends the SIP INVITE message to the 800 service control unit, and the 800 service control unit processes the SIP INVITE message to provide 800 free call connection processing.

 Embodiment 2:

 Assume that the user initiates a 800 free call, that is, sends a SIP INVITE message carrying 800 free call number to the service triggering unit, and the service triggering unit forwards the SIP INVITE message to the centralized service processing unit, and the centralized service processing unit according to the service configuration of the 800 free call service will be The SIP INVITE message is triggered to the 800 service control unit, and the 800 service control unit provides the user with 800 free call services. The specific process is shown in FIG. 5.

 FIG. 5 is a flowchart of a method for processing a service in a packet domain network according to an embodiment of the present invention. The network entity includes a service triggering unit, a centralized service processing unit, and an 800 service control unit, and the specific steps are as follows:

 Step 501: The service triggering unit, for example, the S-CSCF currently registered by the user, receives the SIP INVITE message sent by the user and carrying the 800 free call.

 Step 502: The service triggering unit sends the SIP INVITE message to the centralized service processing unit. In this step, the centralized service processing unit can be located in Service Broker or SCIM.
