Description

Billing association method and system for application service

The present invention relates to an application service charging technology, and in particular, to a charging association method and system for an application service. Background of the invention

At present, a variety of application services have been implemented in the communication system, and the media modes of specific communication include: text, voice, video, and multimedia combination. Application services can be divided into two categories: 1. Content-based services such as: group status display service, streaming media on-demand service, etc. The application server (AS) subscribes or subscribes users by actively sending or responding to user requests. The on-demand media content is sent to the user equipment (UE); Second, the session-based services such as: PoC, Push-to-Talk over Cellular, Conference, etc., AS and each participating The user's UE establishes a session connection to implement communication, and such service is usually used in a group user.

For a content-based service, the AS will assign a charging identifier (CID, Charging Identity) each time the media content is sent to the user, and for the session-based service, each session established between the AS and the UE. A CID will also be assigned, and each assigned CID will be stored in the AS and the service bearer network. The billing center will receive the CDRs carrying the CID from the service bearer network and the AS, and the billing center will close the bills with the same CID: ^ to charge by the application unified method. The allocated CID is also referred to as an IMS Charging Identity (ICID, IMS CID) for an application service in which the service network is an Internet Multimedia Subsystem (IMS).

However, the above CID-based charging method will have several problems in practical applications. The following describes a session-based PoC service as an example. 1. A UE will be assigned an ICID when it establishes a session with the PoC server for the first time in a PoC service process. However, when the current PoC service process has not ended, the UE temporarily withdraws from the service process for some reason, and then rejoins the service process, and the UE is assigned a new ICID. For the UE user, the session established before the temporary withdrawal from the service process and the session established after rejoining the service process are two interrelated sessions, and the two sessions need to be associated with the billing during charging. For the billing center, the two sessions correspond to different ICIDs, which are irrelevant sessions. If the two sessions are to be associated, the billing center should also perform statistics according to the user information in the bill.

Here, the so-called one-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, and each user participating in the current PoC service communication corresponds to one PoC session, and each PoC A session can be called a business for a single user. The related services described in this article are for a single user, that is to say: Each session established by the user with the AS can be called a service. Each time the user sends a subscription request to the AS providing the content service, it can be regarded as a service. .

2. If the sessions of the UEs (that is, the services of the UEs) included in the PoC service process are bound to be charged, the charging center can only perform charging based on the ICID first, and then according to the group information. statistics.

In the above two cases, the charging method is prone to repeated billing, leakage billing, etc., which adversely affects the security and reliability of the billing operation and reduces user satisfaction.

In addition, in order to increase service flexibility and enrich business functions, operators or service providers will add other ASs to the PoC server to provide additional services for PoC services. For example: setting a presence server (Presence Server) in the PoC service network, the presence server can provide a group status display function for the user in the PoC service process; in addition, a location server can be set to provide each participating user. Location information and more. In this way, the operator or service provider may introduce some binding charging policies for PoC services and additional services. but Yes, based on the existing ICID charging technology, the processing logic for associating the PoC service with the charging of the additional service will be more complicated, and various charging errors will inevitably occur, and the development of the charging center will be difficult. Larger, not even implementable.

Not only the PoC service will have the above problems in the charging process, but other application services such as the Conference service have similar charging problems. It can be seen that the existing CID-based charging association method can only associate the operations of the same user in one session, and cannot associate each session of the same user in one business process, and cannot associate one or more business processes. These have become key technical issues to be solved in the development of application business. SUMMARY OF THE INVENTION A charging association method for an application service, the method comprising:

During the service establishment process, it is determined whether the associated service of the current service has been assigned the service charging identifier SCID. If yes, the SCID of the associated service of the current service is extracted as the SCID of the current service; otherwise, the current service is allocated a new one. SCID;

The billing center receives the bills carrying the SCID and associates the bills carrying the same SCID for billing.

In the above solution, the determining is performed in the application server AS of the current service. After extracting the SCID or assigning a new SCID, the method further includes: sending, by the AS, the extracted or newly allocated SCID to the service bearer to which the current service user belongs. The billing center receives bills from the service bearer network and each AS.

In the above solution, the determining is performed in the service bearer network to which the current service user belongs. After extracting the SCID or allocating the new SCID, the method further includes: sending, by the service bearer network, the extracted or newly allocated SCID to the current service. The AS receives the bill from the service bearer network and each AS.

In the above solution, the determining is performed in a separately set charging association unit CCU, After the SCID is extracted or the new SCID is allocated, the method further includes: the CCU sending the extracted or newly allocated SCID to the AS of the current service, and the service bearer network to which the current service user belongs; The network and each AS receive the bill.

In the above solution, the associated service policy and the corresponding relationship between the user and the associated service policy are set in advance, and the associated service policy corresponding to each user includes: information of multiple services associated with the user; the judgment is: The associated service policy corresponding to the current service user is determined, and the associated service of the current service is determined according to the associated service policy, and then it is determined whether the determined associated service has been assigned an SCID.

In the above solution, after the SCID is allocated for the current service, the method further includes: determining an associated service policy corresponding to the current service user, and inserting the currently allocated SCID into the information of the current service in the determined associated service policy; Whether the associated service of the service has been assigned the SCID is: Determine whether the SCID has been inserted into the information of the associated service of the current service in the associated service policy.

In the above solution, the associated service policy corresponding to each user is set as a service package. In the foregoing solution, when the associated service policy is that the service established by the same user and the one or more ASs is related to each other; after the SCID is extracted or the new SCID is allocated, the method further includes: sending a service establishment request carrying the SCID to the current The AS of each associated service of the service; the determining whether the associated service of the current service has been assigned an SCID is: determining whether the currently received service establishment request carries the SCID; when determining that the currently received service establishment request carries the SCID, establishing the service from the service The SCID is extracted from the request as the SCID of the current service.

In the above solution, the related service policy is that the service established by the same user and multiple ASs is an associated service.

A charging association system for an application service, the system is disposed in a communication system of an AS including a service bearer network and one or more services, where the charging association system of the application service includes: a charging association unit CCU and is used for saving Associated business database of associated business policies; The CCU is configured to receive a service establishment request from the service bearer network, read an associated service policy from the associated service database, determine whether an associated service of the current service has been assigned an SCID, allocate an SCID, or extract an allocated SCID from the associated service policy, And send the SCID to the AS.

It can be seen from the foregoing solution that the key of the present invention is: when establishing a service, determining whether the associated service of the current service has been assigned an SCID, and all the associated services are assigned the same SCID; the charging center performs the CDR with the same SCID. Unified billing.

The invention discloses a charging association method for an application service. The method proposes a charging identifier, a service charging identifier (SCID), which is used for charging associations of various services, and the main processing idea of the method is During the service establishment process, for example, when receiving or sending a service establishment request of the user, determining whether the associated service of the current service has been assigned an SCID, and if yes, extracting the SCID to which the associated service has been allocated as the current service. SCID; Otherwise, assign a new SCID to the current service. The billing center receives the bills carrying the SCIDs from the billing related entities in the service network, and associates the bills with the same SCID for unified billing. The associated service policy can be set in advance to configure the associated service of the current service. For example, if the user is to be bound and charged for each user in a PoC service process, the associated service policy can be set as follows: in a PoC service process, each PoC session established by the same PoC server and each user is an associated service; To bind and charge the PoC service and the group status display service used by the same user, set the associated service policy to: PoC service and group status display service established by the same user and the PoC server and the presence status server. For the associated business.

The problem of the PoC service is the most typical in terms of the existing application service charging association. The PoC service is taken as an example to describe the method of the present invention in detail.

FIG. 1 is a schematic diagram of a process flow of a first preferred embodiment of the method of the present invention. As shown in Figure 1, the 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 the user equipment belongs, and the service establishment request carries the personal user identifier, the group identifier, 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 determines, according to the received INVITE message, whether the associated service of the currently established PoC session has been assigned an SCID, and if yes, extracts the SCID of the associated service of the PoC session as the SCID of the PoC session; otherwise, the PoC The session assigns a new SCID.

The associated business policy can be saved in advance, and the correspondence between the user and the associated business policy is also set. For example: Set the mapping relationship between the user ID and the associated service policy identifier. Therefore, the PoC server can read the corresponding associated service policy according to the user identifier in the INVITE message, and determine the associated service of the current service according to the determined associated service policy, thereby determining whether the determined associated service has been assigned the SCID. The method of how the PoC server reads the information of the associated service is a well-known technique and will not be described in detail herein. The off The joint business policy includes: information of one or more interrelated services, such as: service identifier of each service, AS address, and the like.

According to the current development trend of the application service, the associated service policy basically includes three types: 1. In a service process, each session established by the same user and the same AS is an associated service, and this step is determined as: determining the current service. Whether the current user has established a session with the PoC server, and whether the previously established session has been assigned an SCID. 2. In a service process, each session established by the same AS and each user is an associated service. The judgment is: It is judged whether there is a user who has established a session with the PoC server in the current business process, and whether the session that has been established has been assigned the SCID. The service established by the same user and the one or more ASs is an associated service. In this embodiment, the service established by the same user and the PoC server and the Presence server is an associated service, and the step is determined as: determining whether the user has been with the presence server. Establish a service, and whether the service that was established with the presence server has been assigned an SCID. Certainly, the associated services set in the first and second associated service policies may be not limited to the same service process, and the PoC session in different service processes may be set as the associated service, for example, setting the same user in several different services. Each session established with the same AS in the service process is an associated service or the like, and the present invention is not limited thereto. Since an individual user, a group, or a group is likely to sign an affiliate service, the user of the present invention can be broadly understood as: an individual user, or a group, or a group, and the user identifier can be understood in a broad sense. To: individual user ID, or group ID, or group ID. The associated service policy and the correspondence between the user identifier and the associated service policy may be saved independently or in the subscription data, and the subscription data is usually stored in the IMS home subscriber server (HSS, Home Subscriber Server) ).

After the SCID is allocated to the current service, the assigned SCID may 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 determines the related service of the current service in the associated service policy. Whether the SCID exists in the service information can determine whether the associated service of the current service has been assigned the SCID.

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 the response message of 200 OK, but the SCID may also be sent to the IMS through other messages or separately, which is not limited by the present invention.

Step 104: The IMS forwards the step 100 to the UE by the 200 OK message. The SCID in the 200 OK message received in step 103 may be deleted and sent to the UE.

When the third associated service policy is adopted, the user usually needs to establish a group status display service with the Presence server while establishing the PoC service. Therefore, after step 102, step 103 is performed at the same time as step 103. Here, the present invention does not limit the order of execution of steps 103 and 103.

Step 103: The PoC server sends a service establishment request carrying the SCID allocated in step 102 to the Presence server to start the group status display service, where the service request is usually based on the SIP protocol, and includes two parts: a notification (Notify) message and a subscription ( Subscribe ) Message. The Presence server saves the received SCID, and uses the SCID as the SCID of the current service. After completing the group status display service configuration, the device returns a 200 OK message to the PoC server. The 200 OK message may carry the SCID or may not carry the SCID. The invention is not limited.

Here, the Notify message is used to publish the online status of the current UE to the Presence server, and the Subscribe message is used to subscribe the status information of the other participating session users to the Presence server. The PoC server usually sends the SCID to the Presence server through the Notify and Subscribe messages, and can trigger the establishment process of the associated service at the same time. However, the SCID can also be sent to the Presence server through other messages or separately. The information about the service identifier and the AS address corresponding to the PoC service and the group status display service are respectively included in the associated service policy, and the PoC server can determine the address of the Presence server according to the associated service policy. Press this address to send a service establishment request to the Presence server. The address of the Presence server may be any form, such as an IP address or an address in a 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 allocated the SCID by determining whether the currently received service establishment request carries the 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 the SCID is allocated or received, each of the currently established service bills is sent to the billing center, and each bill carries its own SCID. The billing center performs unified billing for bills with the same SCID. Because the associated services described in the associated service policy are assigned the same SCID, the charging center can perform unified charging on the related services to implement the multi-service binding charging policy of the operator or the service provider.

In the above embodiment, when the third associated service policy is adopted, the services established by the same user and the two ASs of the PoC server and the Presence server are related services. In the present invention, the service established by the same user and the two or more ASs may be an associated service, for example, an associated service consisting of a PoC service, a group status display service, and a location service. In the current application service development phase, the associated service between the same user and different ASs may be: any combination of the PoC service, the conference service, the group status display service, and the location service; correspondingly, the AS of each associated service It can include: any combination of the PoC server, the Conference server, the Presence server, and the location server. When the first or second associated service policy is adopted, the service established by the user is usually a PoC service or The 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 related services in the current service, the current service AS, as shown in Figure 1 of the PoC server, should send a service request to the associated service AS of each current service to start each associated service. Since the processing principle for each associated service AS has been described in detail in steps 102, 103, and 103 of Fig. 1, it is no longer detailed.

In addition, the processing in step 102 is not limited to being performed in the PoC server, and may also be performed in the service bearer network to which the current user belongs, or even independently set the processing unit. When the processing described in step 102 is performed in an IMS or independently set processing unit, the method processing is substantially the same as that described in Fig. 1, and will be briefly described below with reference to Figs. 2 and 3.

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

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

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

The IMS can determine, by reading the associated service policy, which associated services are currently established in the PoC session, and determine whether the associated service of the PoC session has been assigned a SCID. Here, similar to FIG. 1, the judgment may be made according to the associated service policy, or may be determined according to whether the received service establishment request carries the SCID. This step can be performed by the Service Call Conference Control Function (S-CSCF) entity in the IMS.

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

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

Similar to FIG. 1, when the third associated service policy is adopted, step 203 may be performed after step 202 and step 203 is performed. Here, the present invention does not limit the execution order of step 203 and step 203.

Step 203: The IMS sends a service establishment request carrying the SCID in step 202 to the Presence server to start a group status display service, where 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 200 OK message to the IMS after completing the group status display service configuration. The 200 OK message may carry the SCID or may not carry the SCID. The invention is not limited.

Here, the present invention does not limit the execution order of the steps 203 and 203. In addition, the IMS usually sends the SCID to the Presence server through the Notify and Subscribe messages, and can trigger the establishment process of the associated service at the same time. However, the SCID can also be sent to the Presence server through other messages or separately, which is not limited by the present invention.

Similarly, the charging center can receive the CDRs carrying the SCID from the IMS, the PoC server, and the Presence server, and perform unified charging for the CDRs having the same SCID to implement the charging association.

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

Step 301: The UE sends an INVITE message to the CCU through the IMS to which the UE belongs. Step 302: The CCU determines, according to the received INVITE message, whether the associated service with the current service has been assigned an SCID, and if yes, extracts the SCID that the associated service has been assigned as the SCID of the currently established PoC session; The established PoC session is assigned a new SCID.

The CCU can determine which related services are currently established in the PoC session by reading the associated service policy, and determine whether the associated service of the PoC session has been assigned a SCID. Here, similar to FIG. 1, the judgment may be made according to the associated service policy, or may be determined according to whether the received service establishment request carries the SCID.

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

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

Step 305: The IMS forwards the 200 OK message to the UE. among them. The IMS can also return the SCID in the 200 OK message and return it to the UE.

Similar to FIG. 1, when the third associated service policy is adopted, step 303 may be performed after step 302 and step 303 is performed. Here, the present invention does not limit the execution order of step 303 and step 303.

Step 303: The CCU sends a service establishment request carrying the SCID in step 302 to the presence server to start the group status display service, where the service request includes: a Notify message and a Subscribe message. The Presence server saves the received SCID, uses the SCID as the SCID of the currently established service, and returns after completing the group status display service configuration. The 200 OK message is sent to the IMS, and the 200 OK 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 steps 303 and 303, and the execution order of steps 304 and 303. In addition, the CCU usually sends the SCID to the Presence server through the Notify and Subscribe messages, and can trigger the establishment process of the associated service at the same time. However, the SCID can also be sent to the Presence server through other messages or separately, which is not limited by the present invention.

The billing center receives the CDRs carrying the SCID from the IMS, the PoC server, and the Presence server, and performs unified charging for the CDRs with the same SCID to implement the charging association.

The associated service policy corresponding to each user in the present invention can be saved in the form of a service package, and the correspondence between the user and the associated service policy becomes the correspondence between the user and the service package, for example, the user identifier and the service package. Correspondence between them. Since operators or service providers often pre-configure several common service packages for individual user selection, only dedicated service packages are developed for groups or groups. Therefore, the correspondence between the individual user and the service package is usually established as: for each service package, the service package and its corresponding individual user identification; and the correspondence between the group or group identifier and the service package Usually established as: Group or group identification and its corresponding individual service packages for each group or group identification. Here, the details of establishing the correspondence between the user identifier and the service package belong to the category of contract data management, which is not the focus of the present invention, and therefore will not be described in detail herein.

In addition, the associated business policy can be pre-stored in an independent database or contracted data and adopt a static management mode, that is, the associated business policy remains unchanged; the associated business policy can also adopt a dynamic management mode, a service provider or an operator, or even The user can send the operation command to the database of the associated business policy in the pre-specified permission range, and create, modify, delete, etc. the associated business policy. For example: an individual user can log in to the web server to browse the web page to operate the associated business policy, and the operator or service The supplier can operate the associated business policy through the operation and maintenance system. The implementation details of the dynamic management mode of the specific associated business strategy are related business strategy management technologies, which are not the focus of the present invention and will not be further detailed in this paper.

The charging association method of the present invention is described in detail by taking the PoC service as an example. When the present invention is applied to other application services, such as the Conference service, the processing flow is similar to that described in FIG. 1 to FIG. 3, except that the processing entity is only processed. And specifically carrying the message only, therefore, this article is no longer - detailed, but is within the scope of the present invention.

Based on the above method of the present invention, the present invention also proposes a billing gateway for application services. The system includes: a Charging Association Unit (CCU) and an associated service database for storing associated business policies.

4 is a schematic structural view 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, AS, and IMS respectively connect the CCU in the charging association system of the UE and the application service. The AS is further connected to the CCU. The CCU receives a service establishment request from the UE from the IMS, extracts an associated service policy from the service database according to the service establishment request, determines an 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 The SCID is assigned; the SCID is assigned, or the assigned SCID is extracted from the associated business policy, and the SCID is sent to the AS.

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, it is also possible to integrate one CCU in each AS. The associated business database can be an independently set database or integrated in the HSS. The CCU and the associated service database may be implemented by software or hardware. Here, if the CCU is integrated in the IMS, it is usually integrated in the Service Call Session Control Function (S-CSCF) entity within the IMS.

In summary, the method and system of the present invention can flexibly and conveniently implement the charging association of various services, and ensure user satisfaction and promote the continuous development of the application service. The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Any modifications, equivalents, improvements, etc. made within the spirit and scope of the invention are intended to be included within the scope of the invention.
