Fig. 2 is the Organization Chart of PCRF cognitive radio Access Network information on load in correlation technique.Wireless access network congestion aware function (RANCongestionAwarenessFunction, referred to as RCAF) by Np interface, unlimited user of access network face congestion information (RANUserPlaneCongestionInformation, referred to as RUCI) is reported to PCRF and carries out strategic decision-making to alleviate network load for PCRF.RCAF is from RAN operation management maintain (OperationAdministrationMaintenance, referred to as OAM) systematic collection user face congestion information.For E-UTRAN, RCAF obtains Node B (EvolvedNodeB in specific evolution by Nq interface from MME, referred to as eNB) UE (IMSI) list for each activation APN under the cellular global identity (EvolvedCellGlobalIdentifier, referred to as ECGI) of/evolution.For UTRAN access, RCAF directly can obtain the IMSI list specific NB/CGI from RAN, and passes through the IMSI list of Nq ' acquisition for each activation APN.Such RCAF just can the IMSI list for each activation APN under each congested base station (eNB/NB)/community (ECGI/CGI).These information reportings are given correct PCRF by RCAF, and PCRF just to these UE Developing Tactics, can alleviate the load of congested base station or community.To report the signaling traffic load of RUCI to PCRF in order to reduce RCAF, RCAF can report PCRF by having the RUCI of an all user of areas of congestion in a piece of news, and the RUCI of the user under multiple areas of congestion can be reported PCRF by certain RCAF in a piece of news.

In the prior art, a public land mobile network (PublicLandMobileNetwork, PLMN) multiple PCRF is usually deployed with in, now DRA will be in charge of these PCRF, and guarantee that controlling session (as Gx, Gxx, Sd session) with an IP-CAN session or the relevant All Policies of UE is all associated with same PCRF.If RCAF needs the RUCI of multiple UE to be aggregated in a message send to a correct PCRF, so the RUCI of the UE managed by same PCRF must be encapsulated in same message and send to a PCRF by RCAF.

In prior art, propose a kind of method reporting RUCI adopting syndication message.As shown in Figure 3, concrete steps are as follows:

301.RCAF reports the congestion information combined for specific UE and APN (i.e. PDN mark).Based on existing DRA routing mechanism, message is sent to correct PCRF;

302:PCRF distributes the PCRF mark of a logic, and logic PCRF mark is carried in the acknowledgement message.RCAF preserves the corresponding relation that UE and APN combination identifies with logic PCRF;

RCAF combines for each new UE and APN and performs aforesaid operations, and such RCAF just can obtain each UE with APN and combine relevant PCRF logical identifier.

The RUCI that multiple UE and APN combines is aggregated in a message and sends to PCRF by 303:RCAF, carries PCRF logical identifier in message;

304:PCRF returns acknowledge message.

In the above-mentioned methods, PCRF needs the PCRF mark returning a logic, and such RCAF can obtain the corresponding relation of UE and APN combination and PCRF logical identifier, to be aggregated in a message by the RUCI belonging to UE and the APN combination that same PCRF manages.Then, PCRF needs the mark of PCRF to send RCAF, and such PCRF will be exposed to client, particularly for agency's (Proxy) DRA pattern, normally the mark of PCRF can not be sent to client.

In order to solve the problem, The embodiment provides a kind of policy control method, device and system.Hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.

Embodiment one

Present embodiments provide a kind of policy control method, describe RCAF and perceive the process that a new UE needs the RUCI reporting this UE relevant to PCRF.Wherein DRA is Proxy pattern, keeps session status between RCAF and PCRF.

Step 401:RCAF reports the congestion information combined for a specific user ID (user ID 1) and PDN mark (PDN mark 1).(RCAF do not preserve user ID 1 and PDN mark 1 combination with the paradigmatic relation that other users combine and PDN combines.) specific implementation time PCRF send DiameterRUCI_Report_Request, carrying RCAF in message is that this Diameter session that will set up distributes session identification (Diameter session identification 1), user ID 1, PDN identifies the RUCI of 1 and this user ID 1 and PDN mark 1 combination.Diameter session establishment sign can also be carried in message.

After step 402:DRA receives message, DRA binding information judgement this user ID of service of preserving according to DRA or the PCRF of user ID and PDN identifier combination, and message is sent to this PCRF.DRA sets up in the process of IP-CAN session at UE, can select a PCRF for this IP-CAN session, and keeps a corresponding relation, as (user ID 1, PDN identifies the IP address of 1, UE1, PCRF address).When DRA receives the message of step 401, the corresponding relation that DRA preserves according to user ID 1, PDN1 mark 1 coupling, sends to correct PCRF by message.DRA upgrades corresponding relation following (session identification 1, user ID 1, PDN identifies the IP address of 1, UE1, PCRF address) simultaneously.

Step 403:PCRF returns acknowledge message to DRA, is DiameterRUCI_Report_Answer message, carries session identification 1 and confirmation code during specific implementation.Can carry in message and report restrictive condition, instruction RCAF reports the RUCI of this user ID and PDN identifier combination under what conditions.

After step 404.DRA receives acknowledge message, judge that having there is at least one Diameter session exists between RCAF and PCRF.

Step 405:DRA returns acknowledge message to RCAF, a Diameter session identification (session identification 2, the session identification of the Diameter session that RCAF the creates during congestion information that this session identification is RCAF in order to report of user mark 2 and PDN mark 1 combination) of the Diameter session between parameter in step 403 message and RCAF and PCRF existed or all session identification lists that there is Diameter session between RCAF and PCRF is carried in message.After RCAF receives message, preserve above-mentioned session identification.According to session identification, RCAF knows all Diameter sessions be present between same RCAF and PCRF.Namely RCAF is also aware of all user ID and PDN identifier combination (for this RCAF, having user ID and the PDN identifier combination of identical PCRF exactly) with identical RCAF and PCRF.Namely RCAF knows all user ID and the PDN identifier combination that can be polymerized transmission in a message.

Step 406:RCAF needs the congestion information (as user ID 1 and user ID 2) reporting multiple user.Particularly, RCAF sends DiameterRUCI_Report_Request message to PCRF, carries session identification 2, the RUCI of user ID 1 and PDN1 identifier combination in message, the RUCI of user ID 2 and PDN mark 1 combination.(also can carry session identification 1 in certain message, RCAF can select any one to be present in the session identification of the Diameter session between RCAF and PCRF in a word).

Message is transmitted to PCRF according to the session state information (i.e. the corresponding relation of session identification 2, PCRF address) of preserving by step 407:DRA;

Step 408:PCRF returns acknowledge message to DRA;

Step 409:DRA forwards acknowledge message to RCAF.

In the above-described embodiments, although DRA likely only returns the session identification of the session that RCAF and PCRF has set up to RCAF.But the paradigmatic relation having obtained this session and other sessions when the session establishment that this session identification returned is corresponding because RCAF is inevitable, although therefore only return the session identification of a session, but the session identification that RCAF still can be returned by this, knows the paradigmatic relation of session and other sessions of setting up.

In other embodiments, DRA can also carry in the acknowledgement message and identify 1 with user ID 1 and PDN and combine and have the right user ID of identical RCAF and PCRF and PDN identifier combination information (user ID that any one session of namely having set up between RCAF and described PCRF is corresponding and PDN identifier combination) (DRA can only return has a right user ID of identical RCAF and PCRF and PDN identifier combination information, also can return and have the right whole user ID of identical RCAF and PCRF and PDN identifier combination information).After RCAF receives message, user ID and PDN identifier combination information.According to user ID and PDN identifier combination information, RCAF knows the user ID and APN identifier combination of being served by same PCRF.Namely RCAF is aware of all user ID and PDN identifier combination (for this RCAF, having user ID and the PDN identifier combination of identical PCRF exactly) with identical RCAF and PCRF.Namely RCAF knows all user ID and the PDN identifier combination that can be polymerized transmission in a message.
