Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of policy control method and device of application.
Background technology
One, telecommunication network for the business that makes customer satisfaction is provided, need solve QoS (Quality of Service service quality) problem end to end in the all-IP evolution process.IP network can provide various business (as VoIP, video request program, file is downloaded, web browses etc.), different business has different requirements to QoS, and to the requirement of chargeing also different (such as can adopting online charging or offline charging, can according to charge on traffic or according to time-based charging etc.).For solving above-mentioned QoS and charging relevant issues, 3GPP has defined PCC (strategy and charging controlled function Policy Control and Charging) framework, satisfies with this different business is carried out different QoS control and charging demand.Among the TS 23.203 the PCC framework is defined, referring to shown in Figure 1, wherein the functional description of each entity is as follows:
AF (Application Function): Application Function.Be mainly PCRF (Policy Control and Charging Rules Function policy control and charging regulation function entity) formulation strategy and charging control rule application layer conversation information dynamically is provided, for example: the P-CSCF among the IMS just belongs to AF.
PCRF: policy control and charging controlled function entity.According to the current ongoing applied business information of restriction, the user of user access network, the configuration of local operator and user signing contract information, work out corresponding strategy, and strategy is offered PCEF (Policy and Charging Enforcement Function strategy and charging execution function entity) execution.Strategy comprises: business data flow detection, QoS control, gate and based on the charging of stream etc.
PCEF: the strategy and the execution entity that charges.Carry out that PCRF issues or the strategy of appointment, promptly finish detection to business data flow, guarantee business data flow QoS, gate, finish the functions such as session of on-line charging and triggering and chain of command.For example: the GGSN entity (Gateway GPRS Support Node GGSN) among the GPRS (General Packet Radio Service GPRS).
Each interface function is described below:
Rx: this reference point is used for AF and issues the application layer conversation relevant information, comprises the required bandwidth information of IP filter, Business Stream that is used for the identification services data flow, and this interface uses the Diameter agreement of ietf definition.
Gx: this reference point is used for PCRF and dynamically controls the PCC rule that PCEF carries out.Possesses following function: set up, safeguard and stop the IP-CAN session; PCEF is to PCRF request PCC rule; PCRF provides PCC rule to PCEF; Consult the IP-CAN carrying and set up pattern etc.This reference point is used the Diameter of ietf definition.
All the other entities (SPR Subscription Profile Repository CAMEL-Subscription-Information storehouse), OCS (Online Charging System Online Charging System), OFCS (Offline Charging System off-line accounting system)) and interface (Sp, Gy, Gz) and content of the present invention irrelevant, repeat no more here.
Two,, set forth several terms earlier in order to be more readily understood the flow process of follow-up introduction:
IP-CAN:IP Connectivity Access Network, when roaming (during position change) in access network, the user still can preserve IP operation continuity (non-interrupting service), access network with such character is called IP-CAN, such as GPRS network, and I-WLAN network etc.
IP-CAN bearer:IP-CAN carrying, has clear and definite speed, the IP transmission path (this path refers to Access Network between the PCEF) of delay and bit rate, IP-CAN carries corresponding PDP (Packet Data Protocol packet data protocol) context for GPRS.
IP-CAN session:IP-CAN session, refer to the incidence relation between UE (User Equipment subscriber equipment) and the PDN (Packet Data Network Packet Data Network), discern by the IP address of UE and the sign of UE (as: international mobile subscriber identity IMSI (International Mobile Subscriber Identity)).As long as UE has distributed the IP address and can have been discerned by IP network, then IP-CAN session (IP-CAN Session) exists.An IP-CAN session can comprise one or more IP-CAN carrying.
Three, the PCC framework of 3GPP definition by PCC rule static or that dynamically provide, is realized the policy control such as QoS, charging, gate to business data flow.Static PCC rule realizes by predefined method on PCRF or PCEF; And dynamically the PCC rule can dynamically be generated by PCRF in entire I P-CAN Session process according to actual needs.When causing the applied business rheology according to application start, change and termination etc., AF dynamically issues the related application business information and gives PCRF, and PCRF can dynamically generate the PCC rule and the PCC rule dynamically is handed down to PCEF using Business Stream according to the applied business information pointer.For example: the user is in multimedia communication process, the interim cancellation of decision video, at this moment can cause the session negotiation information of application layer to be changed, AF need be handed down to PCRF with the applied business information after the change, dynamically generate new PCC rule or change existing PCC rule for PCRF, be handed down to PCEF then and carry out, with the change of control business data flow.
Be a flow process about the control of AF session service Flow Policy below, according to the applied business information that AF issues, PCRF works out the PCC rule and carries out dynamic strategy control, referring to shown in Figure 2, comprises the following steps:
Flow process is described below:
1, after AF receives a trigger event (for example multimedia call control signaling of UE initiation), need set up a new Diameter session;
2, AF extracts the business information (such as the address information of IP stream, port numbers, medium type, bandwidth etc.) that needs from trigger event, and this business information is sent to PCRF by Diameter AAR message;
3, PCRF preserves the business information that receives;
If 4 PCRF do not have user signing contract information at this moment, then to SPR request user signing contract information;
5, PCRF is according to business information that receives and the information (when setting up such as IP-CANSession) that receives from PCEF before this, the IP-CAN Session of AF session association to a correspondence that this is newly-built, and carry out strategic decision-making;
6, PCRF PCC rule that strategic decision-making is drawn offers PCEF and installs, and PCEF returns acknowledge message;
7, PCRF returns AAA message to AF.
Four, PCC architecture definition Rx interface issues the ability of applied business information.
From above-mentioned AF session service Flow Policy control flow as can be seen, the applied business information that PCRF issues according to AF, user signing contract information etc. are finished strategic decision-making.Existing PCC architecture definition adopts Diameter to realize issuing of applied business information by Rx interface, comprises following content in the Business Stream information in the applied business information that issues:
Media Stream: conversation procedure may use a plurality of medium, for example audio frequency, video.M capable (media description is capable) under a Media Stream is used with regard to corresponding IMS in the SDP message.Each Media Stream describes by a Media-Component-Description AVP and by Media-Component-Number AVP sign, Media-Component-Number AVP is exactly the capable serial number that occurs in SDP message of this m.Also comprise out of Memory in the Media Stream: application identities (AF-Application-Identifier) represents that this Media Stream belongs to information such as the reservation priority (Reservation-priority) of what application, medium type (Media-Type), largest request upstream and downstream bandwidth (Max-Requested-Bandwidth-U/DL), stream mode (Flow-Status), Media Stream, RTCP transmitting-receiving bandwidth (RR/RS-Bandwidth), medium coding and decoding (Codec-Data) form.
Medium stream: the sub-stream of medium is the further segmentation to Media Stream, when adopting the RTP mode to transmit such as an audio stream, and not corresponding medium of corresponding rtp streaming and RTCP flow point stream.When applied business information issues, each medium stream is described by a Media-Sub-Component AVP, a plurality of medium stream in the same Media Stream is by Flow-Number AVP sign, and Flow-NumberAVP can number wait ordering according to each medium stream corresponding port.The sub-stream of medium can a corresponding bidirectional flow (comprise two Flow-Description AVP, describes two IP streams), also can a corresponding way flow (only comprise a Flow-Description AVP, describe an IP and flow).Also comprise stream purposes (Flow Usage) and other parameter in the medium stream.These parameters also comprise in Media Stream, illustrate in front, no longer are repeated in this description here.
IP stream: (be collectively referred to as the IP-5 tuple by having identical sources IP address, purpose IP address, transport layer protocol, source port number and destination slogan, if corresponding transport layer protocol does not have the notion of port numbers, source port number and destination slogan can omit) the way flow formed of IP message.On the Rx interface, each IP Flow describes by a Flow-Description AVP.
The applied business information description IMS use in Business Stream information by SDP negotiation, comprise the information such as QoS, gate, charging of Business Stream correspondence.In addition, return under the applied business information and comprise user ID (Subscription-ID), IP address (Framed-IP-Address/Framed-IPv6-Prefix), session priority information such as (Reservation-Priority).

Embodiment
Among the existing IMS, for example: IMS business such as voice, visual telephone, instant message are called as applied business, and described applied business is to provide by IMS AF (Application Function Application Function) etc.IMS AF, as the P-CSCF in the IMS network (Proxy-Call Session Control Function Proxy Call Session Control Function), AS (Application Server: application server) etc., can realize these applied business are carried out the demand of policy control such as QoS, charging by the PCC framework.
Along with rapid development of network, the data applied business among the non-IMS is just becoming more and more abundanter.In non-IMS, for example: business such as video request program, online game, network electronic list, network data meeting, ecommerce, the Internet bank, electronics security are called as the data applied business.Because these data applied business or its comprise the importance of information, perhaps because in order to guarantee user experience, they guarantee to have very high requirement to the QoS that network provides.Electronics security for example, network must guarantee data in real time, transmission accurately, otherwise can influence user's judgement and operation, cause economic loss; And for example the user carries out video request program, lacks under the situation that QoS guarantees at network, may cause that video pictures is fuzzy, sound waits phenomenon off and on; When the user carries out online game for another example, if network can not guarantee for recreation provide QoS, then can't in time pass on server, thereby it is more blunt than the adversary to cause user action, situation such as cause that recreation is suffered a defeat to the data of game operation.
For the data applied business among the aforementioned non-IMS, in case the transmission data take place to postpone or mistake, will have a strong impact on user experience, even owing to loss of data causes and can't commence business; These value-added service flows are different from general business of networking flow simultaneously, network should be realized carrying out different charging control to it according to the difference of business tine, so network needs to provide control abilities such as QoS to these data applied business, charging.
For the policy control that realizes that the PCC framework applications is used in non-IMS data, further use AF (as video-on-demand applications server, online game application server, network data conference applications server etc.) for the data of the data applied business that makes above-mentioned non-IMS, data applied business information can be issued to PCRF, make PCRF can carry out strategic decision-making, thereby satisfy the demand of network policy control such as the QoS of data applied business, chargings.
The policy control method that the embodiment of the invention provides a kind of data to use referring to shown in Figure 3, comprises following key step:
The data that S11, PCRF receive among the non-IMS are used the data applied business information that AF sends.
In the embodiment of the invention, the data among the non-IMS are used the trigger message (for example: receive the request of PCRF or user's request) of AF according to the data applied business, issue data applied business information to PCRF.
Specifically can realize issuing of data applied business information by one of following three kinds of modes:
Mode one, by the IMS applied business stream information unit in the revision Rx interface definition, data are used AF and are issued the data applied business information that comprises data applied business stream information to PCRF.
Comprised a part of professional Business Stream information of forming in the applied business information, for example multimedia conversation business may be made up of video and audio frequency.The Business Stream informational needs that the applied business information that existing PCC architecture definition Rx interface issues comprises is consulted to export in the Media-Component-Description AVP parameter (being IMS applied business stream information unit) according to the SDP under the IMS scene (Session Description Protocol Session Description Protocol), could realize issuing.
Under non-IMS scene, the Media-Component-Description AVP parameter value that is used to describe Business Stream information can't be derived, need revise the IMS applied business stream information unit in the Rx interface definition to this, the SDP negotiation form that is no longer dependent on when making it describe Business Stream information under the IMS scene derives, thereby makes the also satisfied policy control demand to non-IMS data applied business of PCC.
Example is as follows:
Media-Component-Description::＝<AVP?Header:517>
[Media-Component-Number]
*[Media-Sub-Component]
[Media-Type]
[Reservation-priority]
[Flow-Status]
[AF-Application-Identifier]
[Max-Requested-Bandwidth-UL]
[Max-Requested-Bandwidth-DL]
[RS-Bandwidth]
[RR-Bandwidth]
*[Codec-Data]
Wherein Media-Sub-Component AVP representation is as follows:
Media-Sub-Component::＝<AVP?Header:519>
[Flow-Number]
0*2[Flow-Description]
[Flow-Status]
[Flow-Usage]
[Max-Requested-Bandwidth-UL]
[Max-Requested-Bandwidth-DL]
This example with the Flow-Number AVP under Media-Component-Number AVP under the Media-Component-Description AVP structure and the Media-Sub-Component AVP structure as optional parameters.When the IMS applied business stream information unit in the definition of revised Rx interface is used in service application under the IMS scene, Media-Component-Description AVP and Media-Sub-Component AVP need comprise Media-Component-NumberAVP and Flow-Number AVP respectively, wherein Media-Component-Number AVP derives according to " m " row of SDP negotiation message under the IMS application, and Flow-Number AVP is according to the incremental order derivation of the employed port numbers of the capable corresponding Media Stream of each medium; When the IMS applied business stream information unit in the definition of revised Rx interface was used in data applied business under the non-IMS scene, Media-Component-Number AVP and Media-Sub-Component AVP need not to comprise Media-Component-Number AVP and Flow-Number AVP.
Mode two, by newly-increased data applied business stream information unit in Rx interface definition, data are used AF and are issued the data applied business information that comprises data applied business stream information to PCRF.
Under non-IMS scene, Media-Component-DescriptionAVP parameter (the being IMS applied business stream information unit) value that is used to describe Business Stream information can't derive, need in the Rx interface definition, increase data applied business stream information unit newly to this, the SDP negotiation form that is no longer dependent on when making it describe Business Stream information under the IMS scene derives, thereby makes the also satisfied policy control demand to non-IMS data applied business of PCC.
Example is as follows:
Data-Application-Description::＝<AVP?Header:×××>

This example has redefined the expression that Data-Application-Description AVP is used for the data applied business stream information that non-IMS data use.
Data-Application-Description AVP (AVP code * * *) Grouped type is used for the data applied business stream information of representing that non-IMS data are used, the parameter that comprises following (parameter value can expand according to actual conditions):
Data-Description AVP (AVP code * * *) IPFilterRule type is used to represent the five-tuple of Business Stream comprise source address and port numbers, destination address and port numbers, agreement.
Data-Type AVP (AVP code * * *) the Enumerated type, the expression traffic flow types can have following value: AUDIO (0), VIDEO (1), DATA (2)
Data-Status AVP (AVP code * * *) the Enumerated type, expression Business Stream state can have following value: ENABLED (0), DISABLED (1)
Data-Usage AVP (AVP code * * *) the Enumerated type, expression Business Stream purposes can have following value: RTCP (0), OTHER (1)
This parameter and Media-Component-Description AVP are positioned under the Diameter message side by side, and mutual exclusion is used.When PCC is applied to the IMS business, use Media-Component-Description AVP business transferring stream information; Be applied to non-IMS when professional, use Data-Application-Description AVP Data transmission applied business stream information.
Mode three, by http protocol, described data are used AF and are issued data applied business information to PCRF.
Existing PCC framework regulation realizes that the Rx interface that applied business information issues uses Diameter, and to non-IMS data applied business implementation strategy control, because ASP (Applications Service Provider) adopts based on the agreement of web and carries out the information transmission, definition and regulation according to existing PCC framework have obviously limited the application of PCC in non-IMS data applied business.Need set up other agreement Data transmission applied business information, non-IMS data be used the needs that carry out policy control to satisfy PCC.Consider that XML (Extensible Markup Language extend markup language) is in advantage on the data description and the de facto standard status on IP network thereof, data applied business information issues can use the XML grammer to be described, and carries out issuing of data applied business information with HTTP (Hypertext Transfer Protocol HTML (Hypertext Markup Language)) agreement.
An example of using XML syntactic description data applied business information to issue is as follows:
As mentioned above, data applied business information begins with root element " af-session ", be simultaneously " af-session " element set a property " state ", in order to describe the state of " af-session ", can be " session initialization (session begins) ", " session modification (session modification) ", " session termination (session termination) " three kinds of states.The element that the data applied business information that issues is comprised can define according to the XML grammer according to the actual requirements flexibly, for example when non-IMS data applied business was carried out policy control, the Media-Component-Description element was not contained in the XML definition; When Business Stream adopted the RTP mode to transmit for another example, the Data-Description element can occur repeatedly.
Use AF based on above-mentioned three kinds of data and issue one of mode of data applied business information to PCRF, also can in data applied business information, carry Applications Service Provider information.As: Applications Service Provider sign (ASP-Identifier).
For non-IMS data applied business, the situation that exists the identical data applied business to provide by different business provider, when therefore the data application AF among the non-IMS issues data applied business information, except carrying the AF application identities, needs represent the concrete data application, also portability ASP identifies, so that PCRF provides service implementation different policy control for different ASP.
The example that the embodiment of the invention provides a definition ASP sign is as follows:
ASP-Identifier AVP (AVP code * * *), the OctetString type, comprise the identification information of discerning ASP, comprise when issuing data applied business information to PCRF, the different application service provider of identical non-IMS data applied business is provided in order to differentiation by data application AF.
Can be located immediately under the Dimeter conversation message structure for the ASP-Identifier AVP that sets up; Also can place under the Media-Component-Description AVP structure; Can also be by revising AF-Application-Identifier AVP (or AF-Charging-Identifier AVP), make it to comprise Applications Service Provider information, for example by revising AF-Application-Identifier AVP definition, with the addresses of items of mail form as its value, wherein host name partly can be used as the ASP sign, in abc@carrier.com, carrier.com is the ASP sign.
The example that ASP-Identifier AVP is arranged in Diameter conversation message structure is as follows:
<AA-Request>::＝<Diameter?Header:265，REQ，PXY>
......

......
Can find out that from above-mentioned example in data applied business information, identifying by ASPl by ASP-Identifier AVP provides professional and provide professional difference by ASP2.According to the data applied business information that issues, PCRF can provide the professional control strategy of working out for ASPl.
In addition also can be by the configuration Applications Service Provider relevant information (as the ASP configuration information) corresponding on PCRF with data applied business information, PCRF uses the AF address that comprises in the data applied business information that AF issues or domain-name information or other modes according to data and realizes that data applied business information and PCRF go up Applications Service Provider relevant information related of configuration, thereby perception provides the Applications Service Provider of this applied business, and according to this Applications Service Provider relevant information, data applied business information and in conjunction with other policing policy contextual informations is carried out strategic decision-making to using business.
S12, PCRF carry out strategic decision-making according to described data applied business information.
In this step, finish strategic decision-making according to data applied business information and in conjunction with out of Memory.
PCRF uses the data applied business information that AF issues according to data, and finishes strategic decision-making from the information (such as user signing contract information, operator's local policy, access network type) that other entity is known, and is handed down to the PCEF execution.
After PCEF receives control strategy information, according to the policy control such as QoS, charging and/or gate of this control strategy information and executing corresponding data applied business stream.If further control strategy information is gate information, then PCEF uses message to data and filters, and the indication (Disable, Enable etc.) that the message of matched data applied business stream is provided according to the gate control strategy is transmitted or abandoned and waits gate to control; If control strategy information is the Qos control strategy, then PCEF can initiate qos policy control according to the QoS control strategy, carries out the renewal operation of IP-CAN session, operations such as the foundation of for example Qos parameter update of IP-CAN session, or IP-CAN carrying, deletion; If control strategy information is the charging control strategy, then PCEF can be according to the control of chargeing of charging control strategy, as press flow or duration based accounting, the control of chargeing such as online or offline charging.
The embodiment of the invention also provides the data Application Function among a kind of non-IMS, and referring to shown in Figure 4, it comprises: trigger element and issue the unit.

Below be described in further detail this method by two embodiment.
Embodiment three: FTP downloads.Referring to shown in Figure 10, comprise the following steps:
1) finishes the FTP application negotiation between client and the ASP1;
2) ASP1 is handed down to PCRF with the applied business information of downloading service correspondence, and the information of issuing comprises the ASP-Identifier sign, represents that this FTP downloading service is provided by ASP1;
3) PCRF receives the applied business information that ASP1 issues, provide FTP downloading service according to the ASP-Identifier perception by ASP1, and be the professional corresponding strategy of formulating in conjunction with applied business information and other information (carrier policy, user signing contract information, access network type), distribute QoS, formulate charging policy, gate strategy etc. such as the FTP downloading service that provides for ASP1;
4) PCRF carries out policy distribution to PCEF;
5) according to strategy, PCEF carries out the modification of corresponding IP-CAN session;
6) PCRF returns acknowledge message to ASP1;
7) user terminal begins the FTP downloading service, and PCEF controls the downloading service implementation strategy.
Embodiment four: video request program.
Based on the difference of Applications Service Provider strategy or customers, it is that the user provides identical applied business that different Applications Service Providers may require with different QoS.Suppose that ASP_A and ASP_B provide the VOD business, but ASP_A is primarily aimed at VIP client VoD is provided business, and being primarily aimed at normal client, ASP_B provides VoD business, be ASP_A when providing business, require higher QoS to guarantee (for example higher QoS priority, bigger bandwidth etc.) than ASP_B for the client.So the VoD business that Virtual network operator need provide for different Applications Service Providers provides different QoS to guarantee.This moment, PCRF need be according to the ASP information of configuration, and in conjunction with other tactful contextual informations, for the VoD business that Applications Service Provider provides is carried out strategic decision-making.For example ASP_A provides the policy control of VoD business for the user, and idiographic flow is seen shown in Figure 11, comprises the following steps:
1) carries out the negotiation of VOD service between user terminal and the vod server AF;
2) the data applied business information that vod server AF is relevant with video request program is handed down to PCRF; Described data applied business information has comprised the address information of vod server AF and the supported bandwidth range of vod server AF etc.;
3) address information of the vod server AF that comprises in the basis data applied business information of receiving, the ASP configuration information that the PCRF perception is corresponding with this data applied business information, thus this VoD business of perception is provided by ASP_A.PCRF is according to data applied business information, ASP configuration information and in conjunction with other tactful contextual informations, for the VoD business that ASP_A provides is carried out strategic decision-making, such as the higher QoS priority of the traffic assignments of the VoD that provides for ASP_A and bandwidth etc.
4) PCRF carries out the policy distribution of formulating to PCEF;
5) according to strategy, PCEF carries out the modification of corresponding IP-CAN session;
6) PCRF returns acknowledge message to vod server AF;
7) user terminal begins to experience the VoD business.
In sum, the data that PCRF receives among the non-IMS in the embodiment of the invention are used the data applied business information that AF sends; And PCRF carries out strategic decision-making according to described data applied business information.Thereby realized the policy control of PCC, helped promoting experience, the lifting utilization rate of network resource that the user uses non-IMS data non-IMS data applied business.Enlarge the scope of application of PCC in addition, made PCC not only can use the policy control of IMS scene, and made the policy control of PCC under non-IMS scene become feasible.By the embodiment of the invention, network can be realized the policy control such as the data applied business among the non-IMS such as video request program, online game, electronic spreadsheet, data conferencing, ecommerce, the Internet bank, electronics security.
Further, because in conversation procedure, the data applied business information that data application AF among the non-IMS will dynamically change in time is handed down to PCRF, to work out PCC rule control business data flow, obviously increased the flexibility of session in bearing bed control, help the better limited Internet resources of planning, guaranteeing simultaneously provides high quality services for the user.
Further, because the Business Stream information that the applied business information that existing PCC architecture definition Rx interface issues comprises is to use SDP negotiation form down according to IMS to derive, the Media-Component-Description AVP parameter value that promptly is used to describe Business Stream information is derived the SDP negotiation form that need depend under the IMS application.And in non-IMS data application scenarios, realize determining of Business Stream as often using the specialized protocol between online game terminal and the online game application server in the online game application; Though perhaps use SDP, but SDP is used for consultation business service stream between terminal and the data application server, as in the RTSP video-on-demand applications, SDP is mainly used in media address and the medium type of application server to terminal explanation Streaming Media, traffic flow parameters between terminal and the media server is to use the SETUP message of RTSP agreement to hold consultation, and does not use SDP.Therefore the Rx interface of the prior art Media-Component-Description AVP parameter of describing IMS applied business stream information can't be used in non-IMS data application scenarios.
Therefore in the embodiment of the invention, by the IMS applied business stream information unit in the definition of revision Rx interface, the data among the non-IMS are used AF and are issued the data applied business information (being aforesaid way one) that comprises data applied business stream information to PCRF.This implementation is selected different Business Stream information unit attributes, thereby not only can be satisfied purpose of the present invention in different applications, also can take into account the existing application of PCC framework in IMS.
In the embodiment of the invention, also can be by newly-increased data applied business stream information unit in the Rx interface definition, the data among the non-IMS are used AF and are issued the data applied business information (being aforesaid way two) that comprises data applied business stream information to PCRF.This implementation is selected to use different Business Stream information units, thereby not only can be satisfied purpose of the present invention in different applications, also can take into account the existing application of PCC framework in IMS.
Further, because having defined AF, the PCC current mechanism provide the required applied business information of formulation strategy to comprise information such as Business Stream information, charging identifier, IP address and AF application identities to PCRF.If PCC is applied to non-IMS data applied business or based on the existing IMS applied business, existing at the identical data applied business can be by the situation of different business provider operation, when policy control was carried out in this type of data application, PCRF need work out different control strategies according to different service providers.The VOD service of for example carrying out on communication network can be provided by service provider Sohu or Netease, although business provides content the same, but Sohu may take different charging policy with Netease, such as Sohu according to content charging, and Netease takes the mode of charge on traffic, so PCRF need work out different control strategies according to different business provider.But when issuing applied business information, only provide the AF application identities, can't distinguish this business according to this sign by which service provider is provided, thereby can't work out control strategy for VOD service.
Therefore in the embodiment of the invention, in the data applied business information that issues, carry the Applications Service Provider sign, thereby can work out different control strategies at different providers.
Further, because 3GPP stipulates at present, the PCC framework adopts Diameter to carry out the information transmission of Rx interface.And for non-IMS data applied business, because each service provider or network provider all adopt based on the agreement of web and transmit information, therefore in conjunction with the practical application situation of network, will be applied to non-IMS data applied business implementation strategy control to PCC and bring certain difficulty.
Therefore in the embodiment of the invention, provide the scheme that issues non-IMS data applied business information by http protocol, thereby satisfied service provider or network provider transmit information based on the web agreement demand.
PCRF obtains the Applications Service Provider sign in the embodiment of the invention, and carries out strategic decision-making according to described Applications Service Provider sign.Because the Applications Service Provider that Applications Service Provider sign is corresponding different, institute is so that PCRF when carrying out strategic decision-making, can consider may adopt different strategies when different business provider provides identical services.
Further, because having defined AF, the PCC current mechanism provide the required applied business information of formulation strategy to comprise information such as Business Stream information, charging identifier, IP address and AF application identities to PCRF.If PCC is applied to non-IMS data applied business or based on the existing IMS applied business, existing at the identical data applied business can be by the situation of different business provider operation, when policy control was carried out in this type of data application, PCRF need work out different control strategies according to different service providers.The VOD service of for example carrying out on communication network can be provided by service provider Sohu or Netease, although business provides content the same, but Sohu may take different charging policy with Netease, such as Sohu according to content charging, and Netease takes the mode of charge on traffic, so PCRF need work out different control strategies according to different business provider.But when issuing applied business information, only provide the AF application identities, can't distinguish this business according to this sign by which service provider is provided, thereby can't work out control strategy for VOD service.
Therefore in the embodiment of the invention, in the data applied business information that issues, carry the Applications Service Provider sign, the perhaps incidence relation between default Applications Service Provider sign and Applications Service Provider sign on the PCRF and data applied business information, thus can be at the different different control strategies of provider's formulation.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
