In order to avoid causing biggish storage pressure to DRA, user identifier and PCRF mark are stored directly in by the disclosure On the network equipment in communication system.The network for storing user identifier and PCRF mark can be increased in communication system to set It is standby, can also by user identifier and PCRF mark storage existing network element in a communications system, for example, can store SCEF, Certification, authorization and charging (Authentication, Authorization and Accounting, AAA) network element, PCRF, PGW, DRA etc., the disclosure is to the storage location of user identifier and PCRF mark without specifically limiting.

When user identifier and PCRF mark store on such as SCEF or AAA network element, due to SCEF or AAA network element itself With regard to having the function of addressing and carrying out Qos capability requests, therefore, can be directly based upon user identifier that equipment is stored and PCRF identifies to carry out subsequent addressing and capability requests process, and it is real that this kind of equipment can be known as to opening service capability function Body.When in user identifier and the storage of PCRF mark in a communications system other network equipments in addition to SCEF or AAA network element, Such as the network equipments such as PCRF, PGW or DRA, these network equipments may not have the function for addressing and carrying out Qos capability requests Can, therefore, this kind of network equipment can be regarded as storage entity, in this way, SCEF or AAA network element obtains if necessary when being addressed It takes PCRF to identify, then can be identified by being interacted with these storage entities with obtaining the corresponding PCRF of user identifier, thus PCRF is determined by addressing, and then carries out Qos capability requests for UE.In the following, the deployment pair based on above-mentioned two classes different modes Address procedures are described:

Firstly, introduce user identifier and PCRF mark stores address procedures when on SCEF or AAA network element, it is specific to walk Suddenly the process being referred in Fig. 3 A, Fig. 3 A is a kind of flow chart of addressing method shown according to an exemplary embodiment.Such as Shown in Fig. 3 A, this approach includes the following steps.

In step 301, UE establishes the IP CAN session between PGW, and PGW interacts CCR and CCA with PCRF network element, complete At the registration of UE in a communications system.

In the embodiments of the present disclosure, when UE request is registered in a communications system, the IP established between PGW is needed CAN session, and registration information is sent to by PGW based on IP CAN session；When PGW receives the registration information of UE, at least Registrable PCRF network element is chosen in one PCRF network element, and the credit control request for carrying registration information is sent to PCRF network element (Credit Control Request, CCR), so that PCRF network element registers UE after receiving CCR, and is being registered After success, the Credit Control Answer (Credit Control Answer, CCA) for carrying PCRF and identifying is returned to, to PGW so as to PGW PCRF mark is back to UE, completes the registration of UE in a communications system.

In step 302, PGW sends user identifier and PCRF mark to SCEF, and PCRF mark is for where identity user PCRF network element.

Wherein, when user identifier is that UE is registered in a communications system, communication system is unique general identifications that UE is generated, can By fixed network No. code (Mobile Subscriber International ISDN/PSTN Number, MSISDN), the world CUSTOMER ID (International Mobile Subscriber Identification Number, IMSI), user One of public network IP and/or private network IP, access point (Access Point Name, APN) and user's temporary identifier are a variety of Composition.PCRF mark is used for one PCRF of unique identification, and PCRF mark is generally PCRF host name information, and being also possible to other can With unique identification PCRF net element information, such as IP or device numbering etc..

When being registered in a communications system due to UE, it can be registered on a certain PCRF network element in communication system, therefore, After UE succeeds in registration in a communications system, PGW can obtain the PCRF mark of the PCRF network element where UE.In order to obtain SCEF User identifier and PCRF mark are got, and simplifies the process of SCEF request user identifier and PCRF mark, PGW can be actively by user Mark and PCRF mark are uploaded to SCEF, so that SCEF stores user identifier and PCRF mark correspondence.

PGW, can be based on interface existing in current communication networks when user identifier and PCRF mark are sent to SCEF It sends, one or more newly-increased interfaces can also be created in a communications system, and mark user identifier and PCRF based on newly-increased interface Knowledge is sent to SCEF.Wherein, existing interface can connect for open source Asynchronous Programming (Reactive Extensions, Rx) interface, API Mouth or authentication service (Radius) interface.If sending user identifier and PCRF mark based on Radius interface, PGW is by user Mark and PCRF mark are sent to before SCEF, need to generate message based on Radius interface, and addition needs to send out in the message User identifier and the PCRF mark sent generate verifying message, and verifying message are sent to SCEF, by SCEF in verifying message User identifier and PCRF mark are extracted, user identifier and PCRF mark correspondence are stored, so as in subsequent be addressed, SCEF can directly determine PCRF mark corresponding with user identifier.Wherein, PGW is based on Radius interface and generates message be to connect Enter request (Access-Request) message or statistics request (Accounting-Request) message, the disclosure are based on PGW The message that Radius interface generates is without specifically limiting.

In the embodiment of the present application, it is only said so that the network equipment for sending user identifier and PCRF mark is PGW as an example It is bright, and in actual scene, it can also be sent by packet gateway entity, this real-time report user identifier and user Place PCRF mark mode, can to avoid as report not in time and caused by processing delay and processing mistake.

In step 303, when SCEF receives user identifier and PCRF is identified, user identifier is corresponding with PCRF mark Storage.

In the embodiments of the present disclosure, SCEF is after the user identifier and PCRF mark for receiving PGW transmission, since SCEF can To store user identifier and PCRF mark, therefore, SCEF just directly stores user identifier and PCRF mark correspondence, so as to In subsequent be addressed, SCEF can directly determine PCRF mark corresponding with user identifier.

Wherein, SCEF, can be based on the existing interface referred in above-mentioned steps 302 when receiving user identifier and PCRF is identified Or newly-increased interface, the disclosure receive the mode of user identifier and PCRF mark without specifically limiting to SCEF.

It should be noted that process shown in above-mentioned steps 302 and step 303 be PGW actively by user identifier with PCRF mark is uploaded to SCEF, the process stored by SCEF, and during practical application, referring to Fig. 3 B, SCEF is also Following two ways can be taken to obtain user identifier and PCRF mark in PGW.

Mode one, SCEF send the mark acquisition request for carrying user identifier to PGW, and receive user's mark of PGW return Know corresponding PCRF mark.

After UE completes registration in a communications system, since the overall network equipment in communication system can get UE User identifier, in this way, SCEF can request PCRF corresponding with user identifier to identify based on user identifier to PGW.When PGW connects After the user identifier for receiving SCEF transmission, PCRF mark corresponding with user identifier is determined, and PCRF mark is back to SCEF, User identifier and PCRF mark correspondence are stored by SCEF, so that in subsequent be addressed, SCEF can be directly determined PCRF mark corresponding with user identifier.Since PGW is only in the mark acquisition request for receiving SCEF, just PCRF is identified and is sent out It send to SCEF, it can thus be avoided since the UE registered in communication system is excessive, the parallel data that causes SCEF to be likely to be received Excessively, cause the storage pressure of SCEF excessive.

Wherein, PGW, can be based on the side in above-mentioned steps 302 when user identifier and PCRF mark are sent to SCEF Formula is sent, and is no longer repeated herein.

If mode two, PGW are configured with hypertext transfer protocol (HyperText Transfer Protocol, HTTP) head Enhance function, then SCEF obtains the user identifier and HTTP that PGW is sent, and PCRF mark is obtained in the head information of HTTP.

In the embodiments of the present disclosure, if PGW is configured with HTTP enhancing functions, PGW can modify the head information of HTTP, Increase corresponding information in the head information of HTTP, in this way, UE can be accessed directly after UE completes registration in a communications system Network service (Web Server) in SCEF in this way, PGW can detect the access behavior of UE, and obtains UE in access Web PCRF mark is added in the head information of HTTP, HTTP and user identifier is sent to SCEF by HTTP when Server, by SCEF extracts PCRF mark in HTTP, by user identifier and the corresponding storage of PCRF mark, so as in subsequent be addressed, SCEF can directly determine PCRF mark corresponding with user identifier.

Since PGW can directly modify the head information of HTTP, PCRF mark, therefore, nothing are added in the head information of HTTP Other requests for carrying PCRF mark need to be regenerated, simplifies the process of PCRF identification transmission to SCEF, avoids communication system In the requested load excessives for leading to communication system more.

In step 304, SCEF receives the application capability requests of SP/CP, and application capability requests carry user identifier.
