Description

A billing association method and system for application services

technical field

The present invention relates to application service charging technology, in particular to a charging association method and system for application services.

Background technique

At present, a variety of application services have been realized in the communication system, and the specific communication media methods include: text, voice, video, and multimedia combination. Application services can be basically divided into two categories: 1. Content-based services such as: group status display services, streaming media on-demand services, etc. The application server (AS) subscribes users or responds to user requests by actively issuing or responding to user requests The on-demand media content is sent to the user equipment (UE); 2. Session-based services such as push-to-talk (PoC) services in cellular systems, conference (Conference) services, etc., AS establishes session connections with UEs of each participating user To achieve communication, this type of business is usually used among collective users.

For content-based services, every time the AS sends media content to the user, a charging identifier (CID) will be assigned. For session-based services, each session established between the AS and the UE will also be assigned a CID. A CID is allocated, and the allocated CIDs will be stored in the AS and the service bearer network. The billing center will receive bills carrying CIDs from the service bearer network and AS, and each allocated CID corresponds to a bill, and the billing center will associate bills with the same CID to apply a unified method of billing. Wherein, for various application services whose service bearer network is Internet Multimedia Subsystem (IMS), the allocated CID is also called IMS Charging Identifier (ICID).

However, the above CID-based charging method will have several problems in practical application. The following takes the session-based PoC service as an example for description.

1. A certain UE will be assigned an ICID when establishing a session with the PoC server for the first time during a PoC service. But before the end of the PoC service process, the UE temporarily withdraws from the service process for some reason, and then rejoins the service process, and the UE will be assigned a new ICID. For the UE user, the session established before temporarily exiting the service process and the session established after rejoining the service process are two interrelated sessions, and the two sessions need to be associated for charging when charging. For the billing center, these two sessions correspond to different ICIDs and are irrelevant sessions. If these two sessions are to be associated, the billing center will also perform statistics based on the user information in the bill.

Here, the so-called PoC service process is a PoC service communication process established by a PoC session group. The service communication process is composed of multiple PoC sessions. A PoC session can be called a service for a single user. The associated services described in this article are all for a single user, that is to say: each session established between a user and an AS can be called a service, and each time a user sends a subscription request to an AS that provides content services can also be regarded as a service .

2. If it is necessary to bind the sessions of each UE included in a PoC service process for charging, the charging center can only perform charging based on ICID first, and then make statistics based on group information.

The billing methods in the above two cases are very prone to errors such as repeated billing and missed billing, which have a negative impact on the security and reliability of the billing operation, and also reduce user satisfaction.

In addition, in order to increase service flexibility and enrich service functions, operators or service providers will add other application servers (AS) in addition to PoC servers to provide additional services for PoC services. For example: set a presence server (Presence Server) in the PoC business network, the Presence Server can provide users with a group status display function during the PoC business process; in addition, a location server can also be set to provide the location information of each participating user, etc. wait. In this way, operators or service providers may launch some PoC services and additional service binding charging policies. However, based on the existing ICID billing technology, the processing logic for associating the PoC service with the billing of the additional service will be more complicated, and various billing errors will inevitably occur, and the development of the billing center will be difficult Larger, or even impractical.

Not only does the PoC service have the above-mentioned problems in the charging process, other application services such as conference services have similar charging problems. It can be seen that the existing CID-based billing association method can only associate the operations of the same user in one session, but cannot associate the sessions of the same user in a business process, let alone associate one or more business processes , These have become key technical issues to be solved urgently in the development of application business.

Contents of the invention

Detailed ways

The present invention discloses a charging association method for application services. The method proposes a charging identifier for charging association of various services, a service charging identifier (SCID). The main processing idea of the method is as follows: : When receiving or sending the user’s service establishment request, judge whether the associated service with the current service has been assigned an SCID, if yes, then extract the assigned SCID of the associated service as the SCID of the current service; otherwise, it is the SCID of the current service Allocate a new SCID. The billing center receives bills carrying SCIDs from billing-related entities in the service network, and performs unified billing for bills with the same SCID.

Among them, the associated business policy can be preset to configure the associated business of the current business. For example: if you want to bind and charge each user in a PoC service process, you can set the associated service policy as follows: each PoC session established between the same PoC server and each user in a PoC service process is an associated service; and if To bind and charge the PoC service and group status display service used by the same user, set the associated service policy as follows: the PoC service and group status display service established by the same user with the PoC server and presence server for related business.

Since the PoC service has the most typical problems in the existing application service charging association, the method of the present invention will be described in detail below by taking the PoC service as an example.

Fig. 1 is a schematic diagram of the processing flow of the first preferred embodiment of the method of the present invention. As shown in Figure 1, specific processing includes:

Step 101: the user equipment (UE) sends a service establishment request to the PoC server through the service bearer network to which it belongs, and the service establishment request carries an individual user ID, a group ID, and the like.

For the PoC service, the service establishment request is the SIP INVITE message, and the service bearer network is the IMS.

Step 102: The PoC server judges according to the received INVITE message whether the associated service of the currently established PoC session has been assigned an SCID, and if so, extracts the SCID of the associated service of the PoC session as the SCID of the PoC session; otherwise, the PoC The session is assigned a new SCID.

Wherein, the associated service policy may be saved in advance, and the corresponding relationship between the user identifier and the associated service policy shall be set at the same time. Therefore, the PoC server can read the corresponding associated service policy according to the user ID in the INVITE message, and determine the associated service of the current service, thereby judging whether the determined associated service has been assigned a SCID. The method of how the PoC server reads the associated service information is a known technology, and will not be described in detail here. The related service policy includes: information of one or more related services, such as service identifier, AS address and so on.

According to the development trend of the current application business, the associated business strategy basically includes three types: 1. In a business process, each session established by the same user and the same AS is an associated business, then this step is judged as: judging that in this business Whether the current user has ever established a session with the PoC server during the process, and whether the established session has been assigned a SCID; 2. In a business process, each session established by the same AS and each user is an associated service, then this step Judging as: judging whether any user has ever established a session with the PoC server during the current service process, and whether the once established session has been assigned a SCID. 3. The service established by the same user with one or more ASs is an associated service. In this embodiment, the service established by the same user with the PoC server and the presence server is set as an associated service. Then this step is judged as: judging whether the user has ever contacted the presence server Create a service, and whether the service established with the presence server has been assigned a SCID. Of course, the related services set in the above two related service policies are not limited to the same business process, and PoC sessions in different business processes can also be set as related services, for example: set the same user to communicate with Each session established by the same AS is an associated service, etc., which is not limited in the present invention. Since an individual user, a certain group, or even a group may sign related services, the user identification in the present invention can be broadly understood as: an individual user identification, or a group identification, or a group identification. The associated service policy and the corresponding relationship between the user ID and the associated service policy can be stored independently, or can be stored in subscription data, and the subscription data is usually stored in the Home Subscriber Server (HSS) in the IMS.

Wherein, after the SCID is allocated to the current service each time, the allocated SCID can be inserted into the current service information in the associated service policy. Therefore, in step 102, the PoC server reads the associated service policy, and judges whether the associated service of the current service has been assigned a SCID by judging whether there is an SCID in the associated service information of the current service in the associated service policy.

Step 103: The PoC server returns a 200 OK message carrying the SCID extracted or allocated in step 102 to the IMS, and the IMS saves the received SCID and associates the currently established service with the SCID. Here, the PoC server usually sends the SCID to the IMS through a response message of 200 OK, but may also send the SCID to the IMS through other messages or separately, which is not limited in the present invention.

Step 104: The IMS forwards the 200 OK message in step 103 to the UE. Wherein, the SCID in the 200 OK message received in step 103 may be deleted and sent to the UE.

When adopting the third associated service strategy, it is generally required that the user establishes the group status display service with the presence server while establishing the PoC service. Therefore, after step 102, step 103' can be performed while step 103 is performed. Here, the present invention does not limit the execution sequence of step 103 and step 103'.

Step 103': The PoC server sends to the Presence server the SCID service establishment request that carries the allocation of step 102 to start the group status display service. The service request is usually based on the SIP protocol and includes two parts: a notification (Notify) message and a subscription (Subscribe )information. The presence server saves the received SCID, uses the SCID as the SCID of the current service, and returns a 200OK message to the PoC server after completing the configuration of the group status display service. The 200OK message may or may not carry the SCID. Inventions are not limited.

Here, the Notify message is used to publish the current online status of the UE to the Presence server, and the Subscribe message is used to subscribe the presence server to the status information of other users participating in the session. The PoC server usually sends the SCID to the Presence server through Notify and Subscribe messages, and can trigger the establishment process of the associated service at the same time, but it can also send the SCID to the Presence server through other messages or separately, which is not limited in the present invention.

Since the associated service policy read in step 102 includes information such as service identifiers and AS addresses corresponding to the PoC service and the group status display service respectively, the PoC server can determine the address of the presence server according to the associated service policy, thereby pressing This address can send the service establishment request to the presence server. The address of the presence server may be in any form, such as: an IP address, or an address in domain name format, and the like.

In step 103', the PoC server sends a service establishment request carrying the SCID to the Presence server. Therefore, when the third associated service policy is adopted, in step 102, the PoC server can determine whether the associated service of the current service has been assigned an SCID by judging whether the currently received service establishment request carries an SCID. And, when it is judged that the SCID has been allocated, the SCID is extracted from the current service establishment request as the SCID of the current service.

Each billing-related entity in the service network: IMS, PoC server, and presence server, etc., when assigning or receiving SCID, each issue a bill for the currently established service to the billing center, and each bill carries its own SCID, The billing center conducts unified billing for bills with the same SCID. Because the associated services described in the associated service policy are assigned the same SCID, the billing center can charge these associated services uniformly, so as to implement the multi-service binding charging policy of the operator or service provider.

In the above embodiments, when the third associated service policy is adopted, the services established by the same user with the two ASs of the PoC server and the presence server are associated services. In the present invention, it is also possible to set the services established by the same user and two or more ASs as associated services, for example: associated services composed of PoC services, group status display services, and location services. In the current stage of application service development, the related services between the same user and different ASs can be any combination of PoC service, conference service, group status display service, and location service; correspondingly, the AS of each related service It can be any combination of PoC server, Conference server, Presence server and location server. When adopting the first or second associated service strategy, usually the service established by the user is a PoC service or a conference service. In this way, the AS of the current service refers to the PoC server or the conference server.

When there are two or more associated services of the current service, the AS of the current service is shown as the PoC server in Figure 1, and should send a service request to each associated service AS of the current service to start each associated service. Since the processing principle for each associated service AS has been described in detail in step 102, step 103' and step 103 in Fig. 1, it will not be described in detail one by one.

In addition, the processing in step 102 is not limited to be performed in the PoC server, but can also be performed in the service bearer network to which the current user belongs, or even independently set up a processing unit to perform the processing. When the processing described in step 102 is performed in the IMS or an independently configured processing unit, the processing of this method is basically the same as that described in FIG. 1 , and a brief description will be made below in conjunction with FIG. 2 and FIG. 3 .

Fig. 2 is a schematic diagram of the processing flow of the second preferred embodiment of the method of the present invention. As shown in Figure 2, specific processing includes:

Step 201: UE sends an INVITE message to the service bearer network to which it belongs, and the service bearer network is IMS.

Step 202: The IMS judges according to the received INVITE message whether the associated service with the current service has been assigned an SCID, and if so, extracts the assigned SCID of the associated service as the SCID of the currently established PoC session; otherwise, it is the currently established SCID The PoC session is assigned a new SCID.

Wherein, the IMS can determine the associated services of the currently established PoC session by reading the associated service policy, and judge whether the associated services of the PoC session have been assigned SCIDs. Here, similar to that described in FIG. 1 , the judgment can be made according to the associated service policy, or according to whether the received service establishment request carries an SCID. This step can be processed by the Service Call Session Control Function (S-CSCF) entity in the IMS.

Step 203: The IMS sends the INVITE message carrying the SCID allocated or extracted in step 202 to the PoC server. The PoC server saves the received SCID, uses the SCID as the SCID of the currently established PoC session, and returns a 200OK message to the IMS. The 200OK message can be The SCID may or may not be carried, which is not limited in the present invention. Here, the IMS usually sends the SCID to the PoC server through the INVITE message, but may also send the SCID to the PoC server through other messages or separately, which is not limited in the present invention.

Step 204: The IMS forwards the 200 OK message in step 203 to the UE.

Similar to what is described in Fig. 1, when the third associated service strategy is adopted, after step 202, step 203' can be executed while step 203 is executed. Here, the present invention does not limit the execution sequence of step 203 and step 203'.

Step 203': The IMS sends a service establishment request carrying the SCID described in step 202 to the Presence Server to start the group status display service, and the service request includes: a Notify message and a Subscribe message. The presence server saves the received SCID, associates the SCID with the currently established service, and returns a 200OK message to the IMS after completing the configuration of the group status display service. The 200OK message may or may not carry the SCID. Inventions are not limited.

Here, the present invention does not limit the execution sequence of step 203 and step 203'. In addition, the IMS usually sends the SCID to the Presence Server through Notify and Subscribe messages, and can trigger the establishment of associated services at the same time, but it can also send the SCID to the Presence Server through other messages or separately, which is not limited in the present invention.

Similarly, the billing center can receive bills carrying SCIDs from the IMS, PoC server, and presence server, and perform unified billing on bills with the same SCID to realize billing association.

Fig. 3 is a schematic diagram of the processing flow of the third preferred embodiment of the method of the present invention. In this embodiment, an independent charging correlation unit (CCU, Charging Correlation Unit) is set on the service bearer network IMS. As shown in Figure 3, the specific processing includes:

Step 301: UE sends an INVITE message to CCU through its own IMS.

Step 302: According to the received INVITE message, the CCU judges whether the associated service with the current service has been assigned an SCID, and if so, extracts the assigned SCID of the associated service as the SCID of the currently established PoC session; otherwise, it is the currently established SCID The PoC session is assigned a new SCID.

Wherein, the CCU can determine which associated services the currently established PoC session has by reading the associated service policy, and judge whether the associated services of the PoC session have been assigned SCIDs. Here, similar to that described in FIG. 1 , the judgment can be made according to the associated service policy, or according to whether the received service establishment request carries an SCID.

Step 303: The CCU sends the INVITE message carrying the SCID allocated or extracted in step 302 to the PoC server. The PoC server saves the received SCID, uses the SCID as the SCID of the currently established PoC session, and returns a 200OK message to the IMS. The 200OK message can The SCID may or may not be carried, which is not limited in the present invention. Here, the CCU usually sends the SCID to the PoC server through the INVITE message, but may also send the SCID to the PoC server through other messages or separately, which is not limited in the present invention.

Step 304: The CCU returns a 200 OK message carrying the SCID allocated in step 302 to the IMS.

Step 305: The IMS forwards the 200 OK message to the UE. in. The IMS may also delete the SCID in the 200OK message and return it to the UE.

Similar to what is described in Fig. 1, when the third associated service strategy is adopted, after step 302, step 303' can be executed while step 303 is executed. Here, the present invention does not limit the execution sequence of step 303 and step 303'.

Step 303': The CCU sends a service establishment request carrying the SCID described in step 302 to the Presence Server to start the group status display service. The service request includes: Notify message and Subscribe message. The presence server saves the received SCID, uses the SCID as the SCID of the currently established service, and returns a 200OK message to the IMS after completing the configuration of the group status display service. The 200OK message may or may not carry the SCID , the present invention is not limited.

Here, the present invention does not limit the execution order of step 303 and step 303', and the execution order of step 304 and step 303'. In addition, the CCU usually sends the SCID to the Presence Server through Notify and Subscribe messages, and can trigger the establishment of associated services at the same time, but it can also send the SCID to the Presence Server through other messages or separately, which is not limited in the present invention.

The billing center receives bills carrying SCIDs from the IMS, PoC server, and presence server, and performs unified billing for bills with the same SCID to realize billing association.

The associated service policy corresponding to each user ID described in the present invention can be stored in the form of a service package, and the corresponding relationship between the user ID and the associated service policy becomes the corresponding relationship between the user ID and the service package. Because operators or service providers often pre-construct several common service packages for individual users to choose, and only develop dedicated service packages for groups or groups. Therefore, the corresponding relationship between individual user IDs and business packages is usually established as follows: for each business package, the business package and its corresponding individual user IDs; and the correspondence between group or group IDs and business packages The relationship is usually established as: for each group or group identifier, the group or group identifier and its corresponding service packages. Here, the details of establishing the corresponding relationship between the user ID and the service package belong to the category of subscription data management, and are not the focus of the present invention, so this article will not describe it in detail.

In addition, the related service policy can be pre-stored in an independent database or contract data and adopt a static management method, that is, the related service policy remains unchanged; the related service policy can also adopt a dynamic management method, and the service provider or operator, or even Users can create, modify, and delete associated business policies by sending operation commands to the database storing associated business policies within the scope of pre-specified authority. For example: Individual users can log in to the Web server and operate associated service policies by browsing Web pages, while operators or service providers can operate associated service policies through the operation and maintenance system. The specific implementation details of the dynamic management method of related business policies belong to related business policy management technology, which is not the key point of the present invention, and will not be further described in this paper.

Above, taking the PoC service as an example, the billing association method of the present invention is described in detail. When the present invention is applied to other application services such as Conference service, etc., the processing flow is similar to that described in Figures 1 to 3, and the only difference is that the processing entity and the specific messages carried, therefore, this article will not describe them in detail one by one, but they are all within the protection scope of the present invention.

Based on the above method of the present invention, the present invention also proposes a billing association system for application services. The system includes: a charging association unit (CCU) and an associated service database for storing associated service policies.

Fig. 4 is a schematic diagram of the composition and structure of a preferred embodiment of the system of the present invention. As shown in FIG. 4 , the IMS-based application service network includes: UE, IMS, and AS. The IMS is respectively connected to the UE and the CCU in the charging association system of the application service. The AS is further connected to the CCU. The CCU receives the service establishment request from the UE from the IMS, extracts the associated service policy from the associated service database according to the service establishment request, determines the associated service of the current service according to the extracted associated service policy, and determines whether the associated service of the current service has been blocked Allocate SCID; allocate SCID, or extract the allocated SCID from the associated business policy, and send the SCID to the AS.

Wherein, the CCU can be an independently set network entity, or integrated in the IMS. Since there are a large number of ASs in the application service network, a CCU can also be integrated in each AS. The associated business database can be an independent database, or it can be integrated in HSS. The CCU and the associated service database can be realized by software or hardware. Here, if the CCU is integrated in the IMS, it is usually integrated in a Service-Call Session Control Function (S-CSCF) entity within the IMS.

To sum up, the application of the method and system of the present invention can flexibly and conveniently realize the charging correlation of various services, ensure user satisfaction, and promote the continuous development of application services.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present invention are included in the protection scope of the present invention.
