Description

A kind of charge associated and accounting management method of concentrated speech business

Technical field

The present invention relates to the accounting management technical field of communication network, be specifically related to a kind of charge associated and accounting management method of concentrated speech business.

Background technology

Along with development of Communication Technique, Internet protocol (IP) network possesses the ability that voice communication class business is provided, Virtual network operator begin attempting to the user provide semiduplex point to multiple spot, multiple spot to the multi-point speech business, as cluster short message service, cluster graphic service, concentrated speech business (PoC) etc.

PoC service is based on internet protocol multimedia subsystem (IMS Internet Protocol MultimediaSubsystem), by the session flow process between the signaling flow control terminal of supporting Session Initiation Protocol/IP, and provide IP-based group service to terminal by the PoC server under the terminal.

Calling terminal is set up session interaction via the IMS network under the terminal called with terminal called by the IMS network under self.Wherein, the IMS network may comprise CSCF entity (CSCF) and the application server (AS) that service is provided for above-mentioned session service.

In PoC service, be respectively PoC server (PoC Server) under calling terminal and the terminal called for calling terminal and terminal called provide the AS of service.Can be divided into control PoC server (Controlling PoC server) and participate in PoC server (Participating PoC server) according to functions different in session.Concrete difference is to control PoC server and sets up a session by calling out terminal called, can increase or delete the participation member of session in session; Participate in PoCserver and be responsible for setting up terminal and control being connected between the PoC server, and this terminal is controlled according to the subscription data of terminal.When carrying out trunking communication, can be distributed the mutually different IMS charging identifier (ICID) that is used to identify session respectively between each terminal.

Because PoC is the business of a kind of B2BUA (Back to Back User Agent) type, so, the calling terminal of setting up by PoC server and the session between the terminal called are actually and are made up of session between calling terminal and the Controlling PoC server and the session between terminal called and the Controlling PoCserver.Therefore, system will be according to these two the different sessions of calling terminal and terminal called, for calling terminal distributes different ICID respectively with terminal called.

The ICID of above-mentioned calling terminal is distributed by the P-CSCF among the IMS of calling terminal registration, and the ICID of terminal called is then distributed by Controlling PoC server.In the cluster session of some type, the PoC Server under the calling terminal is as Controlling PoC server; And in the cluster session of some other type, the PoC Server under the terminal called is then as Controlling PoC server.

Below, be example with the PoC Server under the calling terminal as Controlling PoC server earlier, concrete ICID distribution method is described.

Referring to Fig. 1, Fig. 1 is a kind of allocation flow figure of prior art ICID, and this flow process may further comprise the steps:

Step 101: in trunking communication, send service request as the IMS of calling terminal A under it.

After proxy call conversation control function entity among the step 102:IMS (P-CSCF) is received described service request, for terminal A distributes an ICID, and this ICID added in the described service request, again service request is sent to the service call session control function entity (S-CSCF) of terminal A registration.

After step 103:S-CSCF receives described service request, preserve the ICID of the terminal A that comprises in the service request, and this service request is sent to the affiliated PoC Server of terminal A.

After PoC Server under step 104: the terminal A receives described service request, preserve the ICID of the terminal A that comprises in the service request, and be to distribute an ICID as called terminal B, certainly, if terminal called has a plurality of, PoC Server then distributes a plurality of different terminal called ICID respectively according to a plurality of terminal called signs that comprise in the service request.

Step 105-107: after distributing terminal called ICID, PoC Server under the terminal A adds described service request with terminal called ICID, and with service request via the IMS under the terminal A, the IMS under the terminal B, send to the PoC Server under the terminal B.

Therebetween, the IMS under IMS, the terminal B under the terminal A preserves the ICID of the terminal B that comprises in the service request.

After PoC Server under step 108: the terminal B receives described service request, preserve the ICID of the terminal A that comprises in the service request and the ICID of terminal B, send service request via the P-CSCF among the IMS of S-CSCF under terminal B of terminal B registration again, the ICID of the terminal A that comprises in P-CSCF and then the preservation service request and the ICID of terminal B.

Step 109: described P-CSCF is all ICID deletion that comprises in the service request of receiving, and the service request that will delete ICID sends to terminal B.

Step 110-116: after terminal B receives service request, via the IMS under the IMS under it, PoC Server, the terminal B under the terminal B, the IMS under the terminal A, the IMS under PoC Server, the terminal A under the terminal A, send to terminal A and to confirm response.

Certainly, the S-CSCF of the S-CSCF of terminal A registration and terminal B registration might be identical, also may be different; PoC Server under the terminal A is possible identical with the PoC Server under the terminal B, also may be different.When above-mentioned S-CSCF and/or these functional entitys of PoC Server are identical, then save the operation between the identical function entity corresponding among Fig. 1.

As the PoC Server under certain terminal called during as Controlling PoC server, concrete ICID allocation flow then as shown in Figure 2, Fig. 2 is the another kind of allocation flow figure of prior art ICID.

ICID distribution method shown in Figure 2 is identical with ICID distribution method principle shown in Figure 1, unique difference is: among Fig. 2, the ICID of all terminal calleds is distributed by the PoCServer under certain terminal called, this PoC Server will add except that the ICID of other terminal called the terminal B in the service request, service request respectively by IMS, the IMS under other each terminal called, the PoC Server under other each terminal called under the terminal B, is sent to the affiliated IMS of other each terminal called; Described IMS sends to service request respectively other corresponding each terminal called after the ICID in the service request is deleted again.Above-mentioned each functional entity is also preserved the called ICID that comprises in the service request in the transport service request.

After above-mentioned Fig. 1, flow process shown in Figure 2, terminal A just can set up session, carry out trunking communication with terminal B and other all terminal calleds.Along with the session operation of calling terminal and each terminal called, IMS can add calling terminal ICID and each terminal called ICID respectively in the ticket that generates subsequently, and sends ticket to charging center.

When billing operation was carried out to ticket in the charging center, the ICID that comprises in the ticket will be discerned in the charging center, and used unified method at the ticket with identical ICID and charge, and then might use diverse ways to the ticket with different IC ID and charge.The charging center might be identical to the applied charging method of the ticket with different IC ID, also might be different, and whether concrete charging method the identical charging logic that is provided with in the charging center that depends on.

Because each operation of each terminal all can generate a ticket, so in the ticket that receive the charging center, the ICID that might have many parts of tickets to have is identical.For this situation, the charging center can be used unified method to these tickets with identical ICID and be chargeed.As seen, prior art is used ICID all operations in the session is associated, and all operations in the session is used unified method charge.

By the above as can be known, prior art is that the calling terminal that belongs to same cohort distributes different ICID respectively with terminal called, and ICID is inserted in the corresponding ticket, uses specific charging method by the charging center according to different ICID afterwards and charges.If then certain terminal is in the trunking communication process, after temporarily having withdrawed from the session flow process of trunking communication for a certain reason, added above-mentioned session afterwards again, IMS can think that the session that this terminal adds again is a new session, and is new ICID of this terminal distribution.Like this, for this user, it withdraws from session of carrying out before and adds the session of carrying out afterwards again, and just becoming two does not have related, different sessions.

Therefore, in follow-up billing operation, described terminal temporarily withdraws from the ICID that is assigned with before the trunking communication and can be added in the corresponding ticket, and described terminal adds the ICID that is assigned with after the trunking communication again and also can be added in the corresponding ticket.Though the ICID difference in the above-mentioned ticket, these tickets in fact all are to generate because of same session flow process that same terminal is carried out, so under the normal condition, these tickets should be used unified method and charge.

Yet, the charging center is during to above-mentioned ticketing, only using specific method according to the ticket with different IC ID charges, so, withdrawing from the cluster session and adding the ticket that is generated after the cluster session again in the same session flow process that above-mentioned same terminal is carried out just might be employed diverse ways and charge.This charging method is unreasonable, has reduced user satisfaction; And very easily produce billing errors such as repeating to charge, leak charging, brought harmful effect for fail safe, the reliability of billing operation.

Summary of the invention

In view of this, main purpose of the present invention is to provide a kind of charge correlation method of concentrated speech business, make in the whole session flow process of PoC communication, each terminal that belongs to same group all ticket that operation produced in group is all associated, so that the ticket that session produced of associated ticket as same group chargeed.

Below accounting management method of the present invention is carried out general description.

It is that calling terminal in the group and terminal called distribute unique PCID that charge correlation method of the present invention makes the Controlling PoC Server that receives service request, and this PCID inserted in the above-mentioned service request, again this service request is sent to the IMS of terminal called registration; The IMS of terminal called registration preserves the PCID that service request comprised that receives, and this service request is sent to terminal called; After terminal called is received service request, send the affirmation response to Controlling PoC Server by the IMS that self registers; Controlling PoC Server inserts above-mentioned PCID in confirming response after, will confirm that response sends to the IMS of calling terminal registration; After the IMS of calling terminal registration receives and confirms response, preserve the PCID that comprises in the affirmation response, and should confirm that response sent to calling terminal.

When accounting management method of the present invention makes Controlling PoC Server receive service request first, be the identical and unique PCID of the terminal distribution of same group; When receiving service request once more, ControllingPoC Server judges whether the terminal that sends this service request belongs to the current group that carries out the cluster session of Controlling PoC Server management, if belong to, then be this terminal distribution and its affiliated identical PCID of group, above-mentioned PCID is inserted the affirmation response, and should confirm that response sent to described terminal, again in the ticket that the IMS under calling/called terminal generates, the ticket that will have an identical PCID charges as the ticket that session produced of same group.

Otherwise, Controlling PoC Server with this terminal as calling terminal, and be this calling terminal with and the pairing terminal called of service request is new distributes identical and unique PCID, afterwards described PCID is inserted service request, and this service request sent to described terminal called via the IMS under the service request terminal called pointed, after terminal called is received service request, send the affirmation response to calling terminal via the IMS under the IMS under self, Controlling PoC Server, the calling terminal; Again in the ticket that the IMS under calling/called terminal generates, the ticket that will have an identical PCID charges as the ticket that session produced of same group.

For accounting management method of the present invention can be described, now reach specific embodiment in conjunction with the accompanying drawings the inventive method is described.

The kind of group service is a lot, as: cluster short message service, cluster graphic service, PoC etc.Be that example describes the inventive method with the PoC service based on IMS only now, then the accounting management method with PoC service is identical for other professional accounting management method as cluster short message service, cluster graphic service etc.

Key point of the present invention: PCID can be distributed by the PoCServer under the calling terminal that belongs to same group, also can be distributed by the PoC Server under the terminal called in this group.Particularly, in the interim cluster conversation as wireless self-networking (Adhoc), the PoCServer under the calling terminal is responsible for setting up and the management cluster session, so distribute PCID by this PoC Server; In the cluster conversation of fixedly group that pre-defines or chat (Chat) pattern, be responsible for setting up and the management cluster session as the PoC Server under keeper's the terminal in calling terminal or the terminal called, so distribute PCID by this PoC Server.

Below, distributing PCID with the PoC Server under the calling terminal earlier is example, and the inventive method is described in detail.

Referring to Fig. 3, Fig. 3 is the charge associated flow chart of a preferred embodiment of the present invention, and this flow process comprises following steps:

Step 301: in trunking communication, send service request as the IMS of calling terminal A under it, wish to set up the cluster session to carry out trunking communication, this service request is generally invite message, wherein comprise as the sign of calling terminal A with as the sign of called terminal B, and the cluster identity of terminal A.The cluster identity that belongs to the terminal of same group is identical, is used to identify current calling/called terminal and belongs to same group.

Step 302: as first and the mutual functional entity of terminal A among the described IMS, after P-CSCF receives described service request, for terminal A distributes an ICID, and this ICID added in the described service request, the service request that will add the ICID of terminal A again sends to the S-CSCF of terminal A registration.

After step 303:S-CSCF receives described service request, preserve the ICID of the terminal A that comprises in the service request, and this service request is sent to the affiliated PoC Server of terminal A.

Described PoC Server is a kind of of AS, be used for providing concentrated speech business based on IMS to terminal, when terminal is registered in the S-CSCF of IMS, IMS selects a PoC Server according to user's subscription data,, be used for providing concentrated speech business as the PoC Server under the described terminal with this PoC Server based on IMS to terminal.

After PoC Server under step 304: the terminal A receives described service request, know that terminal A will set up session, then preserve the ICID of the terminal A that comprises in the service request, and be the unique PCID of all terminal distribution that current trunking communication comprised; Simultaneously, also be to distribute an ICID as called terminal B, a plurality of if terminal called has certainly, PoC Server then distributes a plurality of different terminal called ICID respectively according to a plurality of terminal called signs that comprise in the service request.

Step 305: after distributing PCID and terminal called ICID, PoC Server under the terminal A adds described service request with described PCID and terminal called ICID, sends to as the PoC Server under the called terminal B so that will add the service request of PCID and terminal called ICID.

But,, the PoC Server under the terminal A sends to the S-CSCF that the terminal A among the IMS under the terminal A registers so will having added the service request of PCID and terminal called ICID because the PoC Server under PoC Server and the terminal B under the terminal A can't direct communication.

After the S-CSCF of step 306: terminal A registration receives described service request, PCID that comprises in the preservation service request and the ICID of terminal B.Afterwards, described S-CSCF sends to service request the S-CSCF that registers among the IMS of terminal B under it according to the sign of the terminal B that comprises in the service request.

After the S-CSCF of step 307: terminal B registration receives described service request, preserve the ICID of the PCID, the terminal A that comprise in the service request and the ICID of terminal B, and this service request is sent to the affiliated PoC Server of terminal B.

After PoC Server under step 308: the terminal B receives described service request, preserve the ICID of the PCID, the terminal A that comprise in the service request and the ICID of terminal B, again this service request is sent to the S-CSCF of terminal B registration.

After the S-CSCF of terminal B registration receives described service request, service request is sent between IMS under the terminal B and terminal B P-CSCF as tie point, P-CSCF and then preserve the ICID of the PCID, the terminal A that comprise in the service request and the ICID of terminal B.

Step 309: described P-CSCF is the PCID that comprises in the service request of receiving and all ICID deletion, and the service request that will delete PCID and all ICID sends to terminal B.

Step 310: after terminal B receives service request, send the affirmation response by the P-CSCF among the IMS under it to the S-CSCF of terminal B registration, this affirmation response comprises the sign of terminal A and the sign of terminal B.

Step 311: after described S-CSCF received and confirms response, the PoC Server under terminal B sent and confirms response.

After PoC Server under step 312: the terminal B receives and confirms response, confirm response to the S-CSCF of terminal B registration transmission.

The S-CSCF of step 313: terminal B registration receives that after the affirmation response of the PoC Server under the terminal B according to the sign of the terminal A that comprises in this affirmation response, the S-CSCF that registers sends and confirms response in the IMS of terminal A under it.

After the S-CSCF of step 314: terminal A registration received and confirms response, the PoC Server under terminal A sent and confirms response.

After PoC Server under step 315: the terminal A receives and confirms response, confirm to add the PCID that once distributed in the step 304 in the response, and the affirmation response that will add PCID sends to the S-CSCF that registers among the IMS of terminal A under it at this.

The S-CSCF of terminal A registration receives after the affirmation response of the PoC Server under the terminal A, will confirm that response sends between IMS under the terminal A and terminal A the P-CSCF as tie point.

After step 316:P-CSCF receives and confirms response, preserve the PCID that comprises in this affirmations response, the PCID deletion that comprises in the affirmation that will receive the again response, and the affirmation that will delete PCID responds and sends to terminal A.

Certainly, the S-CSCF of the S-CSCF of terminal A registration and terminal B registration might be identical, also may be different; PoC Server under the terminal A is possible identical with the PoC Server under the terminal B, also may be different.When above-mentioned S-CSCF and/or these functional entitys of PoC Server are identical, then save the operation between the identical function entity corresponding among Fig. 3.

In addition, for trunking communication, terminal A shown in Figure 3 may also communicate by letter with other terminal called that belongs to same group, and terminal B is one in a plurality of terminal calleds.The charge correlation method of using when other terminal called of terminal A and same group is set up the cluster session, identical with method shown in Figure 3, the variation of relative Fig. 3 just replaces with these functional entitys of IMS under PoC Server, the terminal B under the terminal B respectively PoC Server, the IMS under the described terminal called B under the described terminal called, and terminal B replaced with described terminal called, corresponding charge associated flow process then is to carry out at described terminal called.

So, when terminal A receives after the affirmation response of P-CSCF, just can set up session, carry out trunking communication with terminal B and other all terminal calleds.Simultaneously, each functional entity among the IMS has been known PCID, the caller/called ICID of current cluster session, thereby IMS has possessed the ability that generates ticket.In follow-up billing operation, the PCID that once distributed in the cluster session just is added in the ticket.Like this, in the ticket that all operations generated of above-mentioned each terminal, all can comprise identical PCID, that is: PCID is with all telephone bill associations that trunking communication generated.

After ticket is transmitted to the charging center, the PCID that comprises in all tickets will be discerned in the charging center, and use unified method at ticket and charge with identical PCID, then might use diverse ways to the ticket with different PCID and charge, whether concrete charging method the identical charging logic that is provided with in the charging center that depends on.Above-mentioned identification PCID method is identical with the applied recognition methods of prior art.

Because above-mentioned each terminal of carrying out the cluster session all has been assigned with identical PCID, so all can comprise identical PCID in the ticket that the session of each terminal operation is generated, so the charging center in billing operation, will be used unified method to the ticket of each terminal in the cluster session and charge.

If terminal is not to carry out the described normal conversation of present embodiment to set up operation; but carry out the pre-established operation of session; work as terminal so and finish the pre-established operation of session; and the IMS by under it send service request with set up and other terminal between session the time, the charge correlation rule of application is identical with the principle of charge correlation method shown in Figure 3.Difference is the pre-established operation of session when finishing, terminal send by the IMS under it that refer message is set up and other terminal between session; And in the normal conversation flow process shown in Figure 2, terminal then send by the IMS under it that invite message is set up and other terminal between session.

Below, distributing PCID with the PoC Server under the terminal called again is example, and the inventive method is described in detail.

Referring to Fig. 4, Fig. 4 is the charge associated flow chart of another preferred embodiment of the present invention, and this flow process comprises following steps:

Step 401: in trunking communication, send service request as the IMS of calling terminal A under it, wish to set up the cluster session to carry out trunking communication, this service request is generally invite message, wherein comprise as the sign of calling terminal A with as the sign of called terminal B, and the cluster identity of terminal A.The cluster identity that belongs to the terminal of same group is identical, is used to identify current calling/called terminal and belongs to same group.

Step 402: as first and the mutual functional entity of terminal A among the described IMS, after P-CSCF receives described service request, for terminal A distributes an ICID, and this ICID added in the described service request, the service request that will add the ICID of terminal A again sends to the S-CSCF of terminal A registration.

After step 403:S-CSCF receives described service request, preserve the ICID of the terminal A that comprises in the service request, and this service request is sent to the affiliated PoC Server of terminal A.

After PoC Server under step 404: the terminal A receives described service request, preserve the ICID of the terminal A that comprises in the service request, and prepare this service request is sent to as the PoC Server under the called terminal B.But because the PoCServer under PoC Server and the terminal B under the terminal A can't direct communication, so the PoC Server under the terminal A sends to the S-CSCF that the terminal A among the IMS under the terminal A registers with service request.

After the S-CSCF of step 405: terminal A registration receives described service request,, service request is sent to the S-CSCF that registers among the IMS of terminal B under it according to the sign of the terminal B that comprises in the service request.

After the S-CSCF of step 406: terminal B registration receives described service request, preserve the ICID of the terminal A that comprises in the service request, and this service request is sent to the affiliated PoC Server of terminal B.

After PoC Server under step 407: the terminal B receives described service request, know that terminal A will set up session, then preserve the ICID of the terminal A that comprises in the service request, and be the unique PCID of all terminal distribution that current trunking communication comprised; Simultaneously, also be to distribute an ICID as called terminal B, a plurality of if terminal called has certainly, PoC Server then distributes a plurality of different terminal called ICID respectively according to a plurality of terminal called signs that comprise in the service request.

Step 408: after distributing PCID and terminal called ICID, PoC Server under the terminal B adds described service request with described PCID and terminal called ICID, and the service request that will add PCID and terminal called ICID sends to the S-CSCF of the terminal B registration among the IMS under the terminal B.

After the S-CSCF of terminal B registration receives described service request, preserve the ICID of the PCID, the terminal A that comprise in the service request and the ICID of terminal B, again service request is sent between IMS under the terminal B and terminal B P-CSCF, P-CSCF and then preserve the ICID of the PCID, the terminal A that comprise in the service request and the ICID of terminal B as tie point.

Step 409: described P-CSCF is the PCID that comprises in the service request of receiving and all ICID deletion, and the service request that will delete PCID and all ICID sends to terminal B.

Step 410: after terminal B receives service request, send the affirmation response by the P-CSCF among the IMS under it to the S-CSCF of terminal B registration, this affirmation response comprises the sign of terminal A and the sign of terminal B.

Step 411: after described S-CSCF received and confirms response, the PoC Server under terminal B sent and confirms response.

After PoC Server under step 412: the terminal B receives and confirms response, confirm to add the PCID that once distributed in the step 407 in the response, and the affirmation response that will add PCID sends to the S-CSCF that registers among the IMS of terminal B under it at this.

The S-CSCF of step 413: terminal B registration receives that after the affirmation response of the PoC Server under the terminal B according to the sign of the terminal A that comprises in this affirmation response, the S-CSCF that registers sends and confirms response in the IMS of terminal A under it.

The S-CSCF of step 414: terminal A registration preserves the PCID that comprises in the affirmation response after receiving and confirming to respond, and the PoC Server under terminal A sends the affirmation response.

After PoC Server under step 415: the terminal A receives and confirms response, preserve the PCID that comprises in the affirmation response, and will confirm that response sends to the S-CSCF that registers among the IMS of terminal A under it.

After step 416:P-CSCF receives and confirms response, preserve the PCID that comprises in this affirmations response, the PCID deletion that comprises in the affirmation that will receive the again response, and the affirmation that will delete PCID responds and sends to terminal A.

Certainly, the S-CSCF of the S-CSCF of terminal A registration and terminal B registration might be identical, also may be different; PoC Server under the terminal A is possible identical with the PoC Server under the terminal B, also may be different.When above-mentioned S-CSCF and/or these functional entitys of PoC Server are identical, then save the operation between the identical function entity corresponding among Fig. 4.

In addition, for trunking communication, terminal A shown in Figure 4 may also communicate by letter with other terminal called that belongs to same group, and terminal B is one in a plurality of terminal calleds.The charge correlation method of using when other terminal called of terminal A and same group is set up the cluster session, be with the difference of method shown in Figure 4: after as the PoC Server under the terminal B of Controlling PoC Server service request being sent to IMS under the terminal B, IMS under the terminal B sends to IMS under above-mentioned other terminal called with service request, and this IMS preserves the PCID that comprises in the service request of receiving; Again service request is sent to the PoC Server under the terminal called, after this PoC Server preserves the PCID that comprises in the service request of receiving, again service request is sent to the IMS under the terminal called, after P-CSCF among this IMS preserves the PCID that comprises in the service request of receiving, with the PCID in service request deletion, and the service request that will delete PCID sends to terminal called.

After terminal called is received service request,, send the affirmation response to terminal A via the IMS under self, the IMS under the terminal B, the IMS under the terminal A.

If terminal is not to carry out the described normal conversation of present embodiment to set up operation; but carry out the pre-established operation of session; work as terminal so and finish the pre-established operation of session; and by the IMS under it send that service request is set up and other terminal between session the time, the charge correlation rule of application is identical with the principle of charge correlation method shown in Figure 4.Difference is the pre-established operation of session when finishing, terminal send by the IMS under it that refer message is set up and other terminal between session; And in the normal conversation flow process shown in Figure 4, terminal then send by the IMS under it that invite message is set up and other terminal between session.

After finishing the PCID batch operation shown in above-mentioned two embodiment, the non-session operation relevant that terminal is carried out in PoC session with current group, be provided with etc. such as Client-initiated message, session attribute, and the functional entity in the PoC system is during to operation such as Client-initiated state notifying, IMS under the terminal also can produce corresponding ticket, at this moment, also can adopt PCID with corresponding telephone bill association.That is: described IMS, Controlling PoC Server add the PCID that current group is assigned with in the relevant terminal service request.

Afterwards, when IMS generates ticket according to above-mentioned non-session operation, just PCID is added in the ticket so that the non-session operation of each terminal that belongs to same group in group can with the cluster conversation operative association, and then make all tickets of each terminal of same group can use unified method to charge.

By the above as seen, the present invention uses PCID with all session associations in the cluster session, all conversation applications unified method in the cluster session are chargeed, this correlating method and prior art are used ICID with the method that all operations in the session associates, and have identical principle.

Certainly, except can be by above-mentioned service request, confirm that response sends described PCID IMS under calling/called, the PoC Server under calling/called to, can also send described PCID to calling/called affiliated IMS, calling/called affiliated PoC Server by other message, perhaps send described PCID to calling/called affiliated IMS, calling/called affiliated PoC Server respectively by relatively independent message.

In the accounting management of reality operation, if Controlling PoC Server has received certain service request from user, so, corresponding accounting management method just as shown in Figure 5, Fig. 5 is an accounting management flow chart of the present invention, this flow process may further comprise the steps:

The IMS of step 501: terminal A under it sends service request, and this service request is generally invite message, wherein comprises the cluster identity of terminal A, the sign of terminal A and the sign of terminal called.The cluster identity that belongs to the terminal of same group is identical, is used to identify current calling/called terminal and belongs to same group.

Step 502: as first and the mutual functional entity of terminal A among the described IMS, after P-CSCF receives described service request, for terminal A distributes an ICID, and this ICID added in the described service request, the service request that will add the ICID of terminal A again sends to the S-CSCF of terminal A registration.

After step 503:S-CSCF receives described service request, preserve the ICID of the terminal A that comprises in the service request, and this service request is sent to the affiliated PoC Server of terminal A.

After PoC Server under step 504: the terminal A receives described service request, preserve the ICID of the terminal A that comprises in the service request, and prepare this service request is sent to Controlling PoCServer.But because PoC Server and Controlling PoC Server under the terminal A can't direct communications, so the PoC Server under the terminal A sends to the S-CSCF that the terminal A among the IMS under the terminal A registers with service request.

After the S-CSCF of step 505: terminal A registration receives described service request, service request is sent to S-CSCF among the IMS under the Controlling PoC Server.

Step 506: after described S-CSCF receives service request, preserve the ICID of the terminal A that comprises in the service request, and this service request is sent to Controlling PoC Server.

After step 507:Controlling PoC Server receives described service request, know that terminal A will carry out the cluster session.So ICID of the terminal A that comprises in the preservation service request, and judge in the current cluster session by self-management, the cluster identity that comprises in the cluster identity whether cluster session correspondence arranged and the above-mentioned service request is identical, if do not have, Controlling PoC Server determines that then terminal A will initiate trunked call as caller, and step 407 is identical to the operation of step 416 among follow-up operation and Fig. 4.

Receive the affirmation response of P-CSCF among the IMS under self as terminal A after, just can set up session, carry out trunking communication with all terminal calleds in the group, when processing is chargeed to all tickets in the subsequent charging center, will use unified charging method to ticket with identical PCID.

Certainly, in the current cluster session by Controlling PoC Server management, the cluster identity that comprises in the cluster identity that has a cluster session correspondence and the above-mentioned service request is identical.The appearance of this situation generally is because belong to certain terminal in each terminal of this group in the trunking communication process, temporarily withdrawed from the session flow process of trunking communication for a certain reason after, added described session again, and this cluster session is not over yet.At this moment, Controlling PoC Server just determines that terminal A is a member of described cluster session, and then no longer for terminal A distributes new PCID, but the PCID of group under it is distributed to terminal A.

Step 508:Controlling PoC Server adds ICID, the PCID of terminal A in the affirmation response, and will confirm that response sends to the S-CSCF among the affiliated IMS of Controlling PoC Server.

After step 509:S-CSCF receives and confirms response, preserve ICID, the PCID of the terminal A that comprises in confirming to respond, and will confirm that response sends to the S-CSCF that registers among the IMS of terminal A under it.

The S-CSCF of step 510: terminal A registration preserves ICID, the PCID of the terminal A that comprises in the affirmation response of receiving, and will confirm that response sends to the affiliated PoC Server of terminal A.

PoC Server under step 511: the terminal A preserves ICID, the PCID of the terminal A that comprises in the affirmation response of receiving, and the P-CSCF that comprises among the IMS of S-CSCF under terminal A by terminal A registration sends above-mentioned affirmation response.

Step 512:P-CSCF preserves ICID, the PCID of the terminal A that comprises in the affirmation response receive, ICID, the PCID deletion that comprises in the affirmation that will receive the again response, and the affirmation response that will delete ICID, PCID sends to terminal A.

Receive the affirmation response of P-CSCF among the IMS under self as terminal A after, just can add the session of its affiliated group again.Simultaneously, IMS under the terminal A and the IMS under the Controlling PoCServer have all been known the PCID of terminal A, thereby IMS has possessed the ability that generates ticket.In follow-up billing operation, the PCID that once distributed in the cluster session just is added in the ticket.Like this, in the ticket that all operations generated of above-mentioned each terminal, all can comprise identical PCID, that is: PCID is with all telephone bill associations that trunking communication generated.

Because above-mentioned terminal A and other terminal that adds the cluster session again all has been assigned with identical PCID, so all can comprise identical PCID in the ticket that the session of each terminal operation is generated, so the charging center in billing operation, will be used unified method to the ticket of each terminal in the cluster session and charge.

Each terminal that belongs to same group described in Fig. 3, Fig. 4, Fig. 5 just can be chargeed these tickets after all tickets that operation produced are associated by PCID in group as the ticket that same group produced.The charging center is used unified method to the ticket with identical PCID usually and is chargeed when carrying out follow-up billing operation; But operator also can use diverse ways to the ticket of different terminals with identical PCID and charge, as: for two terminals that have identical PCID in the same group, one of them terminal is decided to be the gold card user by operator, it is preferential to enjoy 20% telephone expenses, and another terminal is then gone without any preferential.So, above-mentioned these two two terminals with identical PCID just can not be employed unified method and charge.

Above-described calling/called terminal ICID and PCID, the method that transmits in the functional entity in calling/called IMS territory is generally: calling/called terminal ICID that will distribute and PCID insert in the header field of the PoC service charging vector (P-Charging-Vector) in the SIP signaling message, send the IMS domain-functionalities entity of calling/called terminal to.

By the above as can be seen, the charge correlation method of group service provided by the present invention, in the whole session flow process of PoC communication, each terminal that will belong to same group all telephone bill association that operation produced in group makes above-mentioned ticket can be used as the ticket that same group produces and charges.The accounting management method of group service provided by the present invention, make in the whole session flow process of PoC communication, associated each terminal that belongs to same group all ticket that operation produced in group, the ticket that session produced that is used as same group charges.

The above only is process of the present invention and method embodiment, in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is not equal to replacement, improvement etc., all should be included within protection scope of the present invention.
