Said method (3), (4) are applicable to the standard after the 3GPP R5, bearing bed is by carrying out information interaction between "Policy and Charging Rules Function (PCRF) entity and the traffic/session key-course in the standard after the 3GPP R5, therefore, above-mentioned charging identifier transmits by PCRF.Specifically can be referring to the embodiment shown in Fig. 7,10.

In the above-mentioned method, first three plants the configuration that does not need in advance each layer to be carried out charging policy, first network element that receives content requests of each layer produces charging identifier, be used for related each Internet resources, charge system is unified to charge to the resource with identical charging identifier, realizes accurately chargeing, simultaneously, utilize the charging bill association of charging identifier, avoid repeating chargeing each layer.The 4th kind of method needs in advance at each layer configuring charging strategy, after each layer receives content requests, according to the corresponding charging identifier of acquisition request, makes charge system realize accurately chargeing.

The idiographic flow of using said method can be referring to following embodiment:

Fig. 3 is charge correlation method embodiment two flow charts of the present invention, and this embodiment comprises:

Step 301: terminal sends content requests to the bearing bed network element, as GGSN, is used to initiate a sip message to set up Bearer Channel.

Step 302:GGSN sends to this content requests in the IMS territory of traffic/session key-course.

Step 303: first receives the traffic/session key-course network element of this content requests, as P-CSCF, be responsible for to produce the session charging sign (ICID) of traffic/session control aspect, is used for the ticket that the related network elements in related IMS territory produces.And this session charging sign ICID is inserted in the ChargingVector header field of sip message.

Step 304:SIP signaling is being carried ICID and is being transmitted in the IMS territory, and is delivered to application/content layer by the SIP application access gateway.Like this, application/content layer has just had the charging identifier (ICID) of traffic/session key-course, when generating the content charging ticket, just ICID can be recorded in the content charging ticket.

Service authentication/charging request that step 305:SIP application access gateway will be added with ICID sends to the content submodule, as value added service management platform (VASMP).

Step 306: if service authentication/would charge successfully, value added service management platform (VASMP) is responsible for producing the content charging sign (CCID) of application/content aspect, CCID knows as the principal mark of application/content layer ticket, identifies uniquely at once using or the service recorder of a content.Therefore, different content (content requests), corresponding different content charging signs, different content charging identification records is in different content charging tickets, be that content and content charging ticket are one to one, the several contents request is arranged, and application/content layer just can generate the several contents charging bill.CCID is produced by value added service management platform herein, alternately, the SIP application access gateway also can be used for producing CCID, produces CCID as SIP IAD in step 305, and asks this CCID is sent to value added service management platform by service authentication/chargings.

Step 307: if service authentication/charge successfully, then value added service management platform (VASMP) is carried CCID in giving the service authentication/charge response message of SIP application access gateway, and CCID is passed to the SIP application access gateway.

Step 308:SIP application access gateway will use/and the content charging sign (CCID) of content layer is inserted in the ChargingVector header field of sip message, according to destination address sip message is carried out route, transmit the content requests that carries ICID and CCID and give sip application server.

Step 309:SIP application server is handled according to service logic, and returns corresponding sip response message (service response).

Step 310:SIP application access gateway is transmitted the P-CSCF that this sip message that carries CCID and ICID (service response) is given the IMS territory.The service response that carries ICID and CCID transmits on the IMS territory, thereby the IMS related network elements that session relates to can both obtain CCID and ICID simultaneously.Because in a session, the charging bill that the IMS territory only need adopt unique charging identifier ICID to come a related srvice instance to be produced at this all network element of aspect, for the use of the different content that relates in the service conversation process to the session layer resource, in the ticket in IMS territory, specifically consult (List of SDP MediaComponents is hereinafter to be referred as a SDP item) and come record one by one by media resource.Therefore, when generating the session charging ticket, at the different content in the same session, the same ICID that the session submodule relates to same session is recorded in the same session charging ticket, the CCID that different content is related to is recorded in the different SDP items of this same session charging ticket, it is the different content in the corresponding same session, the traffic/session layer generates a plurality of charging bills unlike application/content layer, and just generate a session charging ticket, writing down an ICID in this session charging ticket, corresponding record the CCID corresponding to different content in the different SDP items of this session charging ticket.

Step 311:P-CSCF is after receiving the service response of returning, by SBLP mechanism, CCID and ICID and media resource (SDP) information of consulting are sent to strategy decisive function (Policy Decision Function by service authorization message, hereinafter to be referred as PDF), PDF is a functional entity among the IMS, and the beared information after the traffic/session key-course will be consulted is controlled the foundation of the Bearer Channel of bearing bed by PDF.In the R5 of 3GPP version, adopted local policy control (SBLP) mechanism to realize the carrying between IMS traffic/session key-course and the bearing bed and the control of chargeing based on business.

Step 312: simultaneously, P-CSCF returns the sip message of service response to terminal after receiving the service response of returning.Because terminal does not produce ticket, so CCID, ICID need not to pass to terminal (UE).

Step 313: terminal (UE) is initiated carrying according to the session negotiation result to GGSN and is set up request, with the Bearer Channel media stream by setting up.

Step 314:GGSN initiates the bearer authorization request to PDF.

Step 315:PDF passes to GGSN with CCID and ICID in authorization response message.GGSN has just obtained other two-layer charging identifier (CCID and ICID) like this, and when generating the carrying charging bill, GGSN will use/and the charging identifier CCID of content layer and the charging identifier ICID of traffic/session key-course record and carry in the charging bill.

Step 316:GGSN is after obtaining bearer authorization, by creating block data protocol context (Packet Data Protocol Context, hereinafter to be referred as PDP Context) come media stream, and be that each PDF context produces the carrying charging identifier (as GCID) at this professional bearing bed.In the R5 version of 3GPP issue, GGSN does not support to distinguish concrete Business Stream, the use of each application/content all needs to activate a new PDP Context in the carrying aspect, therefore, adopt unique charging identifier (as the GCID in the GPRS network) to identify a srvice instance in the operating position of this bearing bed in the face of resource.So, as application/content layer, for different contents, bearing bed produces different GCID, corresponding different GCID, and bearing bed produces different carrying charging bills, promptly has the several contents request just to have several carrying charging bills.For the different content in the same session, referring to Fig. 4, to be recorded in the first carrying charging bill according to a CCID, a GCID and the same ICID that the first content request produces, to be recorded in the second carrying charging bill according to the 2nd CCID, the 2nd GCID and the same ICID that the second content request produces, will be recorded in the 3rd carrying charging bill according to the 3rd CCID, the 3rd GCID and the same ICID that the 3rd content requests produces.

Step 317:GGSN adds this GCID in authorization notification message, and sends to strategy decisive function (PDF).

Step 318:PDF transmits the charging identifier (GCID) of bearing bed to P-CSCF.P-CSCF is inserted in the ChargingVector header field of sip message and transmits at the charging identifier (GCID) that obtains bearing bed afterwards.Therefore the sip message that carries the charging identifier GCID of the charging identifier ICID of charging identifier CCID, traffic/session key-course of application/content layer and bearing bed will transmit in the IMS territory.Like this, the related network elements in IMS territory has just obtained other two-layer charging identifier (CCID, GCID), and in the charging bill that generates this layer, insert other two-layer charging identifier, referring to Fig. 4, session charging ticket for different content generation in the same session, owing to be that therefore same session only produces a session charging ticket, wherein record an ICID, owing to be that therefore different contents can correspondence produce a plurality of GCID and CCID, as record CCID, GCID also will be recorded in the SDP item, promptly corresponding different content will be recorded in the different SDP items with corresponding CCID and the GCID of content, be recorded in the SDP item as a CCID and a GCID who produces according to first content, the 2nd CCID and the 2nd GCID that produce according to second content are recorded in the 2nd SDP item, and the 3rd CCID and the 3rd GCID that produce according to the 3rd content are recorded in the Three S's DP item.Simultaneously, the sip message of charging identifier GCID that carries the charging identifier ICID of charging identifier CCID, traffic/session key-course of application/content layer and bearing bed is transferred to the SIP application access gateway alternately along with the SIP signaling.

Step 319-321: when the user finishes use business or content, the SIP application access gateway will be initiated the request that charging is confirmed to value added service management platform, and the charging identifier (as GCID) of bearing bed is sent to value added service management platform.Like this, application/content aspect has just obtained other two-layer charging identifier (GCID, ICID), value added service management platform is just inserted other two-layer charging identifier when generating ticket, for the different content in the same session, referring to Fig. 4, the one CCID that will produce according to the first content request and a GCID and same ICID are recorded in the first content charging bill, the 2nd CCID that will produce according to the second content request and the 2nd GCID and same ICID are recorded in the second content charging bill, and the 3rd CCID that will produce according to the 3rd content requests and the 3rd GCID and same ICID are recorded in the 3rd content charging ticket.

Above-mentioned flow process is delivered to other each layer with every layer charging identifier, and making all has the charging identifier of other two-layer ticket in the ticket of each aspect, finally realizes three layers charging bill association.Specifically, the P-CSCF in IMS territory by strategy decisive function (PDF) will use/the charging identifier CCID of content layer and the charging identifier ICID of traffic/session key-course pass to bearing bed serve as policy enforcement function (Policy Enforcement Function, hereinafter to be referred as PEF) GGSN, GGSN passes to traffic/session key-course and application/content layer with the charging identifier GCID of bearing bed in replying message.

Above-mentioned flow process shows the situation of using a content in IMS conversation procedure, for the situation that relates to a plurality of contents in the session, at application/content layer, use at each content forms an independently ticket, come mark with unique charging identifier CCID, promptly produce the second content charging identifier corresponding to the second content request; IMS territory at the traffic/session key-course, for the situation that uses a plurality of contents in the conversation procedure, owing to be in a session, so have only a session charging ticket, record the charging identifier ICID of this layer, owing to be a plurality of contents, in this ticket, utilize SDP item (List of SDP Media Components item) to come record one by one, corresponding record carrying charging identifier and content charging sign in each SDP item, it is corresponding first content request, the one SDP item writes down a CCID and a GCID, and the 2nd SDP item writes down the 2nd CCID and the 2nd GCID; In the carrying aspect, because GGSN can't distinguish concrete Business Stream, therefore, each application/content all needs to create new PDP Context and carries, identify by unique GCID, be corresponding first content request, the charging identifier of this layer is a GCID, corresponding second content request, and the charging identifier of this layer is the 2nd GCID.Promptly for the different content of same session, referring to Fig. 4, the session submodule produces same ICID, the carrier module produces different GCID and CCID with the content submodule, corresponding session layer only produces a session charging ticket, bearing bed and application/content layer produce a plurality of carrying charging bills and content charging ticket, the CCID of different content correspondence and GCID are recorded in the different SDP item in the same session charging ticket, and the different CCID of different content correspondence and different GCID and same ICID are recorded in different content charging tickets and the different carrying charging bill.Except above-mentioned charging identifier and write down the difference of the charging bill of above-mentioned sign, be consistent at the flow process of different content request.

Present embodiment makes the charging bill of each aspect that the charging identifier of other aspects all be arranged, can clearly know once and relate to which floor charging in the professional use, the ticket that ticket by any one deck can find other aspects to be associated fast is convenient to carry out various statistical analyses and charge associated.

Fig. 5 is charge associated method embodiment three flow charts of the present invention, and this embodiment comprises:

Step 501: terminal sends content requests to the carrier module, as GGSN, is used to initiate a sip message to set up Bearer Channel.

Step 502:GGSN sends to this content requests in the IMS territory of traffic/session key-course.

Step 503: first receives the traffic/session key-course network element of this content requests, as P-CSCF, be responsible for to produce the session charging sign (ICID) of traffic/session control aspect, is used for the ticket that the related network elements in related IMS territory produces.And this session charging sign ICID is inserted in the ChargingVector header field of sip message.

Step 504:SIP signaling is being carried ICID and is being transmitted in the IMS territory, and is delivered to application/content layer by the SIP application access gateway.Like this, application/content layer has just had the charging identifier (ICID) of traffic/session key-course, when generating the content charging ticket, just ICID can be recorded in the content charging ticket.

Service authentication/charging request that step 505:SIP application access gateway will be added with ICID sends to the content submodule, as value added service management platform (VASMP).

Step 506: if service authentication/would charge successfully, value added service management platform (VASMP) is responsible for producing the content charging sign (CCID) of application/content aspect, CCID knows as the principal mark of application/content layer ticket, identifies uniquely at once using or the service recorder of a content.Therefore, different content (content requests), corresponding different content charging signs, different content charging identification records is in different content charging tickets, be that content and content charging ticket are one to one, the several contents request is arranged, and application/content layer just can generate the several contents charging bill.CCID is produced by value added service management platform herein, alternately, the SIP application access gateway also can be used for producing CCID, produces CCID as SIP IAD in step 505, and asks this CCID is sent to value added service management platform by service authentication/chargings.

Step 507: if service authentication/charge successfully, then value added service management platform (VASMP) sends service authentication/charge response message to the SIP application access gateway, does not carry CCID in this service authentication/charge response message.

Step 508:SIP application access gateway carries out route according to destination address to sip message (content requests), transmits this content requests and gives sip application server.

Step 509:SIP application server is handled according to service logic, and returns corresponding sip response message (service response).

Step 510:SIP application access gateway is transmitted this service response and is given P-CSCF, carries ICID in this service response.The service response that carries ICID transmits on the IMS territory, thereby the IMS related network elements that session relates to can both obtain ICID.Since in a session, the charging bill that the IMS territory only need adopt unique charging identifier ICID to come a related srvice instance to be produced at this all network element of aspect.

Step 511:P-CSCF sends service authorization message to PDF after receiving the service response of returning.

Step 512: simultaneously, P-CSCF returns this service response to terminal after receiving the service response of returning.

Step 513: terminal (UE),, is initiated carrying and is set up request, with the Bearer Channel media stream by setting up as GGSN to the bearing bed network element according to the session negotiation result.

Step 514:GGSN initiates the bearer authorization request to PDF.

Step 515:PDF sends corresponding authorization response message to GGSN.

Step 516:GGSN comes media stream by PDP Context after obtaining bearer authorization, and is that each PDF context produces the carrying charging identifier (GCID) at this professional bearing bed.In the R5 version of 3GPP issue, GGSN does not support to distinguish concrete Business Stream, the use of each application/content all needs to activate a new PDP Context in the carrying aspect, therefore, adopt unique charging identifier (as the GCID in the GPRS network) to identify a srvice instance in the operating position of this bearing bed in the face of resource.So, as application/content layer, for different contents, bearing bed produces different GCID, corresponding different GCID, and bearing bed produces different carrying charging bills, promptly has the several contents request just to have several carrying charging bills.For the different content in the same session, referring to Fig. 6, to be recorded in according to the GCID that the first content request produces in the first carrying charging bill, to be recorded in according to the 2nd GCID that the second content request produces in the second carrying charging bill, will be recorded in according to the 3rd GCID that the 3rd content requests produces in the 3rd carrying charging bill.

Step 517:GGSN adds this GCID in authorization notification message, and sends to strategy decisive function (PDF).

Step 518:PDF transmits the charging identifier (GCID) of bearing bed to P-CSCF.P-CSCF is inserted in the ChargingVector header field of sip message and transmits at the charging identifier (GCID) that obtains bearing bed afterwards.Therefore the sip message that carries the charging identifier GCID of the charging identifier ICID of traffic/session key-course and bearing bed will transmit in the IMS territory.Like this, the related network elements in IMS territory has just obtained the charging identifier (GCID) of bearing bed, and when generating the charging bill of this layer, insert the charging identifier of bearing bed, referring to Fig. 6, session charging ticket for different content generation in the same session, owing to be that therefore same session only produces a session charging ticket, wherein record an ICID, owing to be that therefore different contents can correspondence produce a plurality of GCID, for the use of the different content that relates in the service conversation process to the session layer resource, in the ticket in IMS territory, specifically come record one by one by the SDP item, promptly when generating the session charging ticket, at the different content in the same session, the same ICID that the session submodule relates to same session is recorded in the same session charging ticket, the GCID that different content is related to is recorded in the different SDP items of this same session charging ticket, it is the different content in the corresponding same session, the traffic/session layer generates a plurality of charging bills unlike application/content layer, and just generate a session charging ticket, writing down an ICID in this session charging ticket, corresponding record the GCID corresponding to different content in the different SDP items of this session charging ticket, be recorded in the SDP item as a GCID who produces according to first content, the 2nd GCID that produces according to second content is recorded in the 2nd SDP item, and the 3rd GCID that produces according to the 3rd content is recorded in the Three S's DP item.Simultaneously, the sip message of charging identifier GCID that carries bearing bed is transferred to the SIP application access gateway alternately along with the SIP signaling.

Step 519-521: when the user finishes use business or content, the SIP application access gateway will be initiated the request that charging is confirmed to value added service management platform, and the charging identifier (GCID) of bearing bed is sent to value added service management platform.Like this, application/content aspect has just obtained other two-layer charging identifier (GCID, ICID), value added service management platform is just inserted other two-layer charging identifier when generating ticket, for the different content in the same session, referring to Fig. 6, the one CCID that will produce according to the first content request and a GCID and same ICID are recorded in the first content charging bill, the 2nd CCID that will produce according to the second content request and the 2nd GCID and same ICID are recorded in the second content charging bill, and the 3rd CCID that will produce according to the 3rd content requests and the 3rd GCID and same ICID are recorded in the 3rd content charging ticket.

Charge system just can will be with srvice instance at telephone bill association that each aspect produced according to the charging identifier that comprises in the ticket after receiving the ticket that application/content layer, traffic/session key-course and bearing bed transmit.Wherein:

The item of expression charging identifier is as follows in the application/content layer ticket:

CCID: be used for unique identification application/content layer at the once use of an application or a content.

The ICID:IMS territory is the charging identifier ID that a session produces.

GCID: the charging identifier that GGSN produces for the GPRS PDP Context in the bearer network.

The item of expression charging identifier is as follows in the traffic/session ticket:

The ICID:IMS territory is the charging identifier ID that a session produces.

GCID: GGSN is the charging identifier that the GPRS PDP Context produces in the bearer network, specifically is included in the Access Correlation id field among the SDP Media Component of ticket.

The item of expression charging identifier is as follows in the bearing bed ticket:

Above-mentioned flow process shows the situation of using a content in IMS conversation procedure, for the situation that relates to a plurality of contents in the session, at application/content layer, use at each content forms an independently ticket, come mark with unique charging identifier CCID, promptly produce the second content charging identifier corresponding to the second content request; IMS territory at the traffic/session key-course, for the situation that uses a plurality of contents in the conversation procedure, owing to be in a session, so have only a session charging ticket, record the charging identifier ICID of this layer, owing to be a plurality of contents, in this ticket, utilize SDP item (List of SDP Media Components item) to come record one by one, corresponding record carrying charging identifier in each SDP item, it is corresponding first content request, the one SDP item writes down a GCID, and the 2nd SDP item writes down the 2nd GCID; In the carrying aspect, because GGSN can't distinguish concrete Business Stream, therefore, each application/content all needs to create new PDP Context and carries, identify by unique GCID, be corresponding first content request, the charging identifier of this layer is a GCID, corresponding second content request, and the charging identifier of this layer is the 2nd GCID.Promptly for the different content of same session, referring to Fig. 6, the session submodule produces same ICID, the carrier module produces different GCID and CCID with the content submodule, corresponding session layer only produces a session charging ticket, bearing bed and application/content layer produce a plurality of carrying charging bills and content charging ticket, the GCID of different content correspondence is recorded in the different SDP item in the same session charging ticket, the different CCID of different content correspondence are recorded in the different content charging tickets with different GCID and same ICID, and the different GCID of different content correspondence are recorded in the different carrying charging bills.Except above-mentioned charging identifier and write down the difference of the charging bill of above-mentioned sign, be consistent at the flow process of different content request.

Embodiment one shown in Figure 3, owing to will realize the mutual transmission of the charging identifier of interlayer, flow process is relatively complicated; Simultaneously, because need to pass down the charging identifier CCID of application/content aspect, except need be on the basis of existing local policy SBLP based on business, present interfaces is expanded, in interface message, expand outside the field of the charging identifier CCID that writes down application/content aspect, also need the ticket that IMS territory and GGSN are produced is expanded, add the field of the charging identifier CCID of record application/content aspect.Therefore, embodiment one need do some expansions to the standard of 3GPP, and is bigger to the influence of system.And present embodiment makes the charging bill on upper strata that its down charging identifier of structure at all levels all be arranged, the ticket that the ticket by the upper strata just can find other aspects to be associated fast, and the clear easy realization of association process need not be revised present interfaces agreement and ticket substantially; In addition, owing to only need the unidirectional delivery of the charging identifier of realization interlayer, flow process is relatively simple, implements little to the influence of system.

Fig. 7 is charge associated method embodiment four flow charts of the present invention, and this embodiment comprises:

Step 701: terminal sends carrying and sets up request to the bearing bed network element, as GGSN.

Step 702:GGSN comes media stream by creating PDP Context, and is that each PDF context produces the carrying charging identifier (GCID) at this professional bearing bed.In the version after R5, introduce to distinguish the technology of different business stream at bearing bed after, GCID can not be used for the ticket of application/content of unique identification at bearing bed.Because GGSN supports to distinguish concrete Business Stream, the use of a plurality of application/contents can be shared a PDP Context in the carrying aspect, does not need to activate a new PDP Context again.In the enhancement mode ticket eG-CDR of the GGSN that supports FBC/PCC, it is business datum table (List of Service Data) that a ticket item is arranged, be used for writing down the details of each Business Stream specially, mainly comprise wholesale price group (Rating Group) at this Business Stream, charging regulation library name (Charging Rule Base Name), the time (Time Usage) of using, uplink traffic (Data Volume Uplink), downlink traffic (Data Volume Downlink), application function recorded information (AF-Record-Information) etc., wherein, application function recorded information (AF-Record-Information) item can specifically comprise the charging identifier of coming from the application function biography, as the CCID of application/content layer and the ICID of traffic/session key-course.

Step 703: terminal sends content requests to GGSN, is used to initiate a sip message to set up Bearer Channel.

Step 704:GGSN sends to this content requests in the IMS territory of traffic/session key-course.

Step 705: first receives the traffic/session key-course network element of this content requests, as P-CSCF, be responsible for to produce the session charging sign (ICID) of traffic/session control aspect, is used for the ticket that the related network elements in related IMS territory produces.And this session charging sign ICID is inserted in the ChargingVector header field of sip message.

Step 706:SIP signaling is being carried ICID and is being transmitted in the IMS territory, the related network elements in related IMS territory.

Step 707:SIP application access gateway is sending service authentication/charging request to value added service management platform.

Step 708: if service authentication/would charge successfully, the content submodule, as, value added service management platform (VASMP) is responsible for producing the content charging sign (CCID) of application/content aspect, CCID knows as the principal mark of application/content layer ticket, identifies uniquely at once using or the service recorder of a content.CCID is produced by value added service management platform herein, alternately, the SIP application access gateway also can be used for producing CCID, produces CCID as SIP IAD in step 705, and asks this CCID is sent to value added service management platform by service authentication/chargings.Referring to Fig. 8, for different content in the same session, when generating the content charging ticket, because the CCID that different contents is corresponding different, and then corresponding different content charging ticket, as being recorded in the first content charging bill according to the CCID that the first content request generates, will be recorded in the second content charging bill according to the 2nd CCID that the second content request generates, will be recorded in the 3rd content charging ticket according to the 3rd CCID that the 3rd content requests generates.

Step 709: if service authentication/charge successfully, then value added service management platform (VASMP) is carried CCID in giving the service authentication/charge response message of SIP application access gateway, and CCID is passed to the SIP application access gateway.

Step 710:SIP application access gateway carries out route according to destination address to sip message, and content requests is transmitted to sip application server.

Step 711:SIP application server is handled according to service logic, and returns corresponding sip response message (service response).

Step 712:SIP application access gateway adds ICID, CCID in the service response, and transmits the session submodule (P-CSCF) that this service response that carries CCID and ICID is given the IMS territory.The service response that carries ICID and CCID transmits on the IMS territory, thereby the professional IMS related network elements that relates to can both obtain CCID and ICID simultaneously.Because in a session, the charging bill that the IMS territory only need adopt unique charging identifier ICID to come a related srvice instance to be produced at this all network element of aspect, for the use of the different content that relates in the service conversation process, in the ticket in IMS territory, specifically come record one by one by the SDP item to the session layer resource.Therefore, when generating the session charging ticket, the session submodule is recorded in ICID in the session charging ticket, CCID is recorded in the SDP item of session charging ticket.Referring to Fig. 8, for contents different in the same session, when generating the session charging ticket, owing to be that therefore same session produces an ICID, session charging ticket of corresponding generation, because a plurality of contents, to be recorded in the different SDP items of session charging ticket according to the different CCID that a plurality of contents produce, as being recorded in the SDP item according to the CCID that first content produces, to be recorded in according to the 2nd CCID that second content produces in the 2nd SDP item, will be recorded in the Three S's DP item according to the 3rd CCID that the 3rd content produces.

Step 713:P-CSCF is after receiving the service response of returning, by PCC mechanism, CCID and ICID and media resource (SDP) information of consulting are sent to "Policy and Charging Rules Function (Policy Charging Rule Function is hereinafter to be referred as PCRF) by the request of PCC rule creation.PCRF is a functional entity among the IMS, and the beared information after the traffic/session key-course will be consulted is controlled the foundation of the Bearer Channel of bearing bed by PCRF.It in Fig. 3 and embodiment shown in Figure 5 R5 version at 3GPP, adopted local policy control (SBLP) mechanism to realize the carrying between IMS traffic/session key-course and the bearing bed and the control of chargeing based on business, and 3GPP R5 and before the charging way of version mainly be charging in the carrying aspect at PDP Context, development along with the IMS standard and the market demand, its limitation mainly shows as: the R5 charging way can't be distinguished different IP Flow, and charging way is not suitable for other access way (WLAN, xDSL, Cable.....); Support that the terminal quantity of secondary PDP Context is limited, secondary PDPContext takies the processing and the storage resources of mobile phone terminal, and shortens battery life; In addition, the activation of PDPContext and deexcitation can roll up the signaling consumption in the GPRS/UMTS system, and have increased the time delay of professional foundation.Therefore, among the 3GPP R6, bearing bed introduced can differentiated service stream charging (Flow Based Charging is hereinafter to be referred as the FBC) mechanism based on stream, a PDP Context can carry a plurality of Business Streams.In R7 and R8 standard, again the policy control and the control of chargeing are combined, merge strategy decisive function (PDF) with based on the billing function (FBC) that flows, a kind of new framework has been proposed, (Policy and Charging Control is controlled in i.e. strategy and charging, hereinafter to be referred as PCC), be used for realizing that the functional entity on upper strata is to the carrying strategy of bearer network layer and the control of chargeing.Utilize FBC or PCC mechanism, application/content layer and traffic/session key-course can realize and bearing bed between strategy and the transmission of charging control information.

Step 714:PCRF passes to carrier module (GGSN) by the PCC rule with CCID and ICID.GGSN has just obtained other two-layer charging identifier (CCID and ICID) like this, so that generate the carrying charging bill time, carrier module (GGSN) will use/the charging identifier CCID of content layer and the charging identifier ICID of traffic/session key-course record and carry in the charging bill.Referring to Fig. 8, for contents different in the same session, when generating the session charging ticket, in the version after the R5, because bearing bed is introduced the technology of distinguishing different business stream, GCID can not be used for the charging bill of application/content of unique identification at bearing bed, need be with CCID, ICID is recorded in the charging bill of sign bearing bed in business datum (Service Data) item, as GCID being recorded in the carrying charging bill, in the first business datum item that will be recorded in this carrying charging bill according to a CCID and the same ICID of first content request generation, in the second business datum item that will be recorded in this carrying charging bill, in the 3rd business datum item that will be recorded in this carrying charging bill according to the 3rd CCID and the same ICID of the 3rd content requests generation according to the 2nd CCID and the same ICID of second content request generation.Concrete CCID, ICID can be recorded in application function recorded information (AF-Record-Information) item of business datum item.

Step 715:GGSN returns the response of PCC rule to PCRF.

After step 716:P-CSCF receives service response, this service response is transmitted to terminal.

Step 717-719: when the user finishes use business or content, the SIP application access gateway will be initiated the request that charging is confirmed to value added service management platform, and value added service management platform is returned corresponding charging and confirmed response, finishes charging flow.

Above-mentioned flow process shows the situation of using a content in IMS conversation procedure, for the situation that relates to a plurality of contents in the session, at application/content layer, use at each content forms an independently ticket, come mark with unique charging identifier CCID, promptly produce the second content charging identifier corresponding to the second content request; IMS territory at the traffic/session key-course, for the situation that uses a plurality of contents in the conversation procedure, owing to be in a session, so have only a session charging ticket, record the charging identifier ICID of this layer, owing to be a plurality of contents, in this ticket, utilize SDP item (List of SDP Media Components item) to come record one by one, corresponding record carrying charging identifier and content charging sign in each SDP item, it is corresponding first content request, the one SDP item writes down a CCID, and the 2nd SDP item writes down the 2nd CCID; In the carrying aspect, because GGSN supports to distinguish concrete Business Stream, therefore, each application/content does not need to create new PDP Context and carries, GCID can not be used for the ticket of application/content of unique identification at bearing bed, different content also needs to come record with the item of the different business data (ServiceData) in the eG-CDR ticket in the use of bearing bed, the CCID, the ICID that are about to corresponding first content request are recorded in the first business datum item, and the 2nd CCID, the ICID of corresponding second content request is recorded in the second business datum item.Except above-mentioned charging identifier and write down the difference of the charging bill of above-mentioned sign, be consistent at the flow process of different content request.

Present embodiment, in the implementation of business, by Session Initiation Protocol will use/the charging identifier CCID of content aspect is delivered to the IMS territory of traffic/session key-course, by FBC/PCC mechanism will use/the charging identifier ICID in the charging identifier CCID of content aspect and the IMS territory of traffic/session key-course is delivered to the bearing bed gateway.Then, the network element that obtains other aspect charging identifier is inserted into the charging identifier that obtains in separately the charging bill, wherein, the charging identifier CCID of the application that the network element in IMS territory will obtain/content aspect is inserted in the SDP Media Component ticket item relevant with this time content, a CCID who is about to corresponding first content request is recorded in the SDP item of session charging ticket, and the 2nd CCID of corresponding second content request is recorded in the 2nd SDP item of session charging ticket; Support the charging identifier ICID in the IMS territory of the charging identifier CCID of application/content aspect that the GGSN of FBC/PCC enhancement mode will obtain and traffic/session key-course to be inserted in application function recorded information (AF-Record-Information) subitem in the Service Data ticket item relevant with this time content, a CCID, the ICID that is about to corresponding first content request is recorded in the first business datum item of carrying charging bill, and the 2nd CCID, the ICID of corresponding second content request is recorded in the second business datum item of carrying charging bill.After charge system is received the charging bill that three aspects transmit, can associate according to the charging bill of three aspects that relate in the use of charging identifier information that comprises in lower floor's ticket a valued added applications/content, support that operator takes flexibly charge mode to finish wholesale price and ticket is examined and made cuts, avoid repeating chargeing, realize accurate charging towards content.
