Hereinafter, by taking user's request multimedia telephony services as an example, reference picture 1 simultaneously combines Fig. 2, and the systems approach to the present invention is described.

Fig. 2 is to trigger the systems approach flow chart that the network equipment 1, the charging triggering network equipment 2 and counting equipment 3 carry out charging according to the application service relevant information of the application service of acquisition according to the application service of the specific embodiment of the present invention.

The terminal device that one user uses supports multimedia telephony services.The business of a mediaphone is initiated in user request, because the user is the initiator of session, hereinafter referred to as the user is calling subscribe, and the opposing party for being called calling subscribe referred to as called subscriber, in multimedia telephony services, calling subscribe and called subscriber can increase new media business newly during call.For example, a visual telephone is initiated in the short codes of calling user dials called subscriber, request.Then the user equipment of calling subscribe generates a conversation request message, wherein the conversation request message includes the identification information of calling subscribe and the identification information of called subscriber, also include the type for the business that calling subscribe asks, i.e. IMS communication business identifications (IMS-Communication-Service-Identifier A VP).The user equipment of calling subscribe sends the conversation request message to service call conversation control function equipment（ S-CSCF ).

Service call conversation control function equipment judges whether the conversation request message routing to the application service triggering network equipment 1 according to the internal logic of oneself.

In the step s 100, the application service triggering network equipment 1 gets the conversation request message from service call conversation control function equipment 6, the conversation request message includes session correlated identities information, that is the identification information of calling subscribe and the identification information of called subscriber, also include the IMS communication business identifications that calling subscribe asks, wherein, the IMS communication business identifications are video call service for identifying the type of service that the session is asked.

In the present embodiment, the session correlated identities information in conversation request message had both contained the identification information of calling subscribe, also contains the identification information of called subscriber.Because even being the situation to caller charging, when calling subscribe sets up these three the different types of calls of local traffic, national distance or international long-distance, its expenses standard is different, accordingly, it would be desirable to which the identification information of called subscriber is to distinguish different expenses standards.In the embodiment of a change, for example, in the case of only allowing calling user dials local call, because the call will not be because It is affected for the difference of called subscriber, therefore, session correlated identities information can only include the identification information of calling subscribe.Similarly, for the situation of called subscriber's charging, if the difference of calling subscribe does not interfere with the expenses standard of called subscriber, similarly, session correlated identities information can only include the identification information of called subscriber.

In step S 101, application service triggers the number of called subscriber of the network equipment 1 first in the conversation request message, for example, the number is 6246, it is a short codes to judge 6246, and determine that the session needs to call short codes server, the number is then routed into short codes server 4d.Short codes server 4d searches the mapping table between the short codes of its storage inside and physical number, to determine the physical number corresponding to the short codes 6246 as 13512345678, the physical number is back to the application service triggering network equipment 1 by short codes server 4d.Because the session have invoked the service that short codes server 4d is provided, therefore, the application service triggering network equipment 1 preserves short codes server 4d business of the identification information application service triggering network equipment 1 always according to calling subscribe's request in conversation request message, that is video call service, judge that the session needs to call audio server 4a and video server 4b, then the application service triggering network equipment 1 allows audio server 4a and video server 4b to receive the conversation request message and respond calling for the session, the application service triggering network equipment 1 further obtains audio server 4a identification information 0001 and video server 4b identification information 0010 respectively.

In step s 102, application service triggers the network equipment 1 by the identification information of the application service relevant information, i.e. each application server of request call of the application service of request call, including：The identification information 0010 of short codes server 4d identification information 0100, audio server 4a identification information 0001 and video server 4b, and the identification information of calling subscribe and the identification information of called subscriber are supplied to the charging triggering network equipment 2 by internal interface.

In step S 103, charging triggering Wang Network equipment 2 obtains the application service relevant information for the application service that the network equipment 1 is triggered from application service, that is the identification information 0010 of short codes server 4d identification information 0100, audio server 4a identification information 0001 and video server 4b, and calling subscribe identification information and the identification information of called subscriber.

Prestored a database inside the charging triggering network equipment 2, preserves each application clothes Whether business device needs the information of charging, and the charging triggering network equipment 2 searches the database, judges whether multiple application servers that this session request is called need charge.For example, in the database, the strategy formulated according to operator, the charging triggering network equipment 2 determines to call short codes server 4d to charge, and call audio server 4a and video server 4b to need to be charged, and audio server 4a and video server 4b are the application server of online charging.

In step S014, the audio server 4a and video server 4b of the online charging as needed of the charging triggering network equipment 2 identification information 0001 and 0010 and the identification information of calling subscribe and called subscriber generate an on-line charging request message.

In step S 105, the on-line charging request message is sent the online charging subsystem 3a into counting equipment 3 by online charging interface Ro by the charging triggering network equipment 2.

In Bu Sudden S 106, online charging subsystem 3a is obtained after on-line charging request message, according to the identification information of calling subscribe therein and called subscriber, and the online account balance information for the calling subscribe that prestored in online charging subsystem 3a, according to this account balance amount information, online charging subsystem 3a determines whether the application service that the calling subscribe and called subscriber of session call the audio server 4a and video server 4b of online charging to be provided.

Specifically, if the charge type that calling subscribe and called subscriber are added is charged for the initiator for application service, that is, when conversation initial is set up or in communication process, the application service of calling subscribe's request call is paid by calling subscribe；If in communication process, the one or more application services of called subscriber's request call, if then these application services need charging, are paid by the called subscriber for initiating the application service.Therefore, in the session of the present embodiment, the audio server 4a and video server 4b of the online charging of calling subscribe's request call are responsible for paying by calling subscribe.Online charging subsystem 3a judges whether the remaining sum of the online account of calling subscribe is enough, if enough, higher than one predetermined threshold value of the remaining sum of the online account of such as calling subscribe, then online charging subsystem 3a mandate calling subscribes and called subscriber use the application service that it is asked.

In addition, maintaining the mapping table between the application server identifier information of online charging and application server group mark, i.e. table 1 in online charging subsystem 3a.Online charging subsystem 3a is according to table 1, it may be determined that one or more application server institute's knobs into application service The corresponding application server group for online charging of device combination is identified.

Table 1

Specifically, online charging subsystem 3a judged results are called after the application service that the audio server 4a and video server 4b of online charging are provided for the calling subscribe and called subscriber of permission session in step s 106, in step s 107, online charging subsystem 3a needs to determine its corresponding application server group mark according to application server audio server 4a and video server 4b identification information, and table 1.In the present embodiment, the session request that calling subscribe initiates call application server identifier information by 0001 audio server 4a and application server identifier information for 0010 the services that provide of video server 4b, therefore, online charging subsystem 3a according to table 1 determine two online chargings seat with server corresponding to the application server group for charging be designated Π Ι.

In Bu Sudden S108, online charging subsystem 3a identifies III, strategy of setting price according to the application server group.Specifically, online charging subsystem 3a identifies Ι Π according to the application server group, determines its corresponding expense computation rule, includes whether to use promotion plan, and give a discount plan, incentive plan etc..Different application server group marks can influence expense computation rule, below only one example：Be designated I application service group I corresponding chargings unit price for unit price 1 (namely, rate is unit price 1, charging per minute for unit price 1), be designated II application service group II corresponding chargings unit price for unit price 2 (namely, rate is unit price 2, charging per minute for unit price 2), be designated the III corresponding charging of application service group 111 unit price for unit price 3 (namely, rate is unit price 3, charging per minute for unit price 3).These specific expense computation rules, can be set or the adjust automatically during operation of counting equipment 3 by Virtual network operator according to specific network operation situation.

Therefore, in step S109, online charging subsystem 3a ^^ are according to the rate information corresponding to the account balance and application service group of calling subscribe（For example, one minute receives how much） Estimating allows the time span information of call, to generate the mandate relevant information of application service, including the application server audio server for authorizing calling subscribe and called subscriber to use it to ask

4a and video server 4b and the time span information for allowing to converse of estimation.

In the embodiment of a change, relevant information is authorized only to include the application server audio server 4a and video server 4b for authorizing calling subscribe and called subscriber to use it to ask.If user is pay-per-use or monthly payment user, time span information can not included by authorizing in relevant information.

In step S 1 10, online charging subsystem 3a sends the mandate relevant information to the charging triggering network equipment 2.

In step S1 11, the charging triggering network equipment 2, which is received, comes from online charging subsystem

After the 3a mandate relevant information to application service, the charging triggering network equipment 2 triggers the mandate relevant information that the network equipment 1 provides the application service to application service.

In step S 1 12, the application service triggering network equipment 1 receives the mandate relevant information of the application service from the charging triggering network equipment 2, namely the application service for allowing calling subscribe and called subscriber to be provided using application server audio server 4a and video server 4b.After the authorization grant of online charging subsystem, the application service triggering network equipment 1 allows calling subscribe and called subscriber to use the application service authorized.

When a session persistence after a period of time, when terminating session by Online Charging System 3a due to reasons such as the user's fee account balance deficiencies of the session, Online Charging System 3a determines actual rate（Charging in such as one minute how much）, and based on the actual duration of call, actual cost of the phone call is determined, and the message of conversation end is returned into calling subscribe and called subscriber；When a session is terminated by calling subscribe or called subscriber, Online Charging System 3a determines actual rate, and based on the actual duration of call, it is determined that actual cost of the phone call.

In the above-described embodiments, in step S106, online charging subsystem 3a judges higher than one predetermined threshold value of remaining sum of the online account of calling subscribe, the then application service for authorizing calling subscribe and called subscriber to use it to ask.In the embodiment of a change, in step S 106, online charging subsystem 3a judges that Sorry, your ticket has not enough value in the online account of calling subscribe, then online charging subsystem 3a generates a mandate relevant information in step S 109, is taken including the application for not allowing calling subscribe and called subscriber to be provided using the application server of request Business.

Then in step S 110, online charging subsystem 3a sends the mandate relevant information to the charging triggering network equipment 2.

Further, in step S111, the charging triggering network equipment 2 receive from online charging subsystem 3a to the mandate relevant information of application service and be supplied to application service to trigger the network equipment 1 the mandate relevant information to the application service, wherein, the application service provided application server audio server 4a and video server 4b that the mandate relevant information of the application service includes not allowing user to ask using it, therefore, the conversation request message is employed service trigger Wang Network equipment 1 and terminated, the service trigger network equipment 1 will not be employed to route at called subscriber, therefore, the session can not be set up.

In the above-described embodiments, calling subscribe only initiates a conversation request message, in the embodiment of a change, calling subscribe or called subscriber can also be after session be set up, change the application service of its request call, illustrated below by taking the application service that calling subscribe asks change to be called as an example, ask the situation for changing the application service called similar with calling subscribe in communication process for called subscriber, will not be described here.

Reference picture 3, in step S 1 13, application service triggering net Network equipment 1 also needs to detect whether the application server called changes, namely, whether calling subscribe or called subscriber go back new application server of the request call in addition to the audio server 4a and video server 4b that have called, or calling subscribe or called subscriber's request terminate the audio server 4a and/or video server 4b called.

If Video service is exited in calling subscribe's request, while calling new instant message service, then the user equipment of calling subscribe sends a conversation request message to S-CSCF, including the information for exiting Video service and the service of request call instant message.The conversation request message is transmitted to the application service triggering network equipment 1 by S-CSCF.In step S 114, the application service triggering network equipment 1 finds that application server changes, including the session is exited in video server 4b requests, and server of instant message 4c requests are added in the session.Then the video server 4b requests that identification information is 0010 are exited server of instant message 4c that session and identification information are 001 1 request and add the identification information of session and the session by the application service triggering network equipment 1 sends to the charging triggering network equipment 2. The charging triggering network equipment 2 and counting equipment 3 repeat Bu Sudden S103, to SI 12,.Specifically, in step S103', the charging triggering network equipment 2 obtains the application service relevant information for the application server that the network equipment 1 is triggered from application service, terminate the video server 4b for calling identification information to be 0010, after new request call identification information is 001 1 server of instant message 4c, the charging triggering network equipment 2 judges whether two application servers need charging.According to the list of the application server of charging the need for internal maintenance, the charging triggering network equipment 2 determines that video server 4b is to need the application server of charging, and is the application server of online charging；The charging triggering network equipment 2 determines that server of instant message is to need the application server of charging, and is the application server of offline charging.

In step S104', the charging triggering network equipment 2 calls the identification information to be according to termination

0010 video server 4b generates an on-line charging request message, and according to the server of instant message 4c that new request call identification information is 0011, generates an offline charging request message.

In step S105, in, the charging triggering network equipment 2 is sent the on-line charging request message to online charging subsystem 3a by online charging interface Ro, and is sent the offline charging request message to offline charging subsystem 3b by offline charging interface Rf.

In the present embodiment, when generating an offline charging request message, the charging triggering network equipment 2 is just immediately sent the offline charging request message into offline charging subsystem 3b by Rf interface, and the opportunity that above-mentioned offline charging message sends offline charging request message is only an example.In actual charge system, there is the regulation of correlation on the opportunity that offline charging request message is sent in DIAMETER agreements.For DIAMTER agreements, with reference to htt://www. ietf.org/rfc/rfc3588.txt, for the regulation of Rf interfaces, with reference to http://www.3gpp.org/ftp/Specs/html-info/32299.htm .Rf interfaces support the offline charging request message based on DIAMTER agreements, and the state of offline charging request message includes starting（), start transit time（Interim) and stop（) and event stop（Event) etc..

Online charging subsystem 3a and offline charging subsystem 3b in counting equipment 3 receive on-line charging request message and offline charging request message from the charging triggering network equipment 2 respectively.In counting equipment 3, maintain that up to the present a session called is all The sequence table of application service, therefore, counting equipment 3 know all application servers that the session has currently been called.According to the sequence table, in the application service of online charging is needed, counting equipment 3 knows the video server 4b that session termination calls identification information to be 0010.

Then, in step S106', online charging subsystem 3a obtains the identification information of calling subscribe and called subscriber, and the online account balance information for the calling subscribe that prestored in online charging subsystem 3a, according to account balance amount information, online charging subsystem 3a determines whether the application service that the calling subscribe and called subscriber of session call the audio server 4a of online charging to be provided.

In addition, maintaining the mapping table between the application server identifier information of offline charging and application server group mark, i.e. table 2 in offline charging subsystem 3b.Root Ju table 2, offline charging subsystem 3b can determine the application server Suo Group of one or more offline chargings into the corresponding application server group for the being used for charging mark of application server combination.
