Description
Technical field
The present invention relates to 3GPP (3rd Generation Partnership Project; Third generation partner program) grouping system of evolution (EPS:Evolved Packet System), the particularly system of selection of the policy billing control server in this system.
Background technology
3GPP (3rd Generation Partnership Project; Third generation partner program) grouping system of evolution (EPS:Evolved Packet System) is by E-UTRAN (Evolved UniversalTerrestrial Radio Access Network; The UMTS land radio access web of evolution), MME (Mobility Management Entity; Mobile management unit), S-GW (Serving Gateway, gateway), P-GW, claim PDN GW (Packet Data Network Gateway again; Grouped data network gateway), HSS (Home Subscriber Server; Home subscriber server), AAA (Authentication, Authorization and Accounting, the authentication and authorization charging) server of 3GPP, PCRF (Policy and Charging Rules Function; "Policy and Charging Rules Function) entity and other support nodes are formed, and also the PCRF entity are called policy billing control server in the literary composition.Wherein MME is responsible for the chain of command related work such as processing and the contextual management of user's mobile management of mobile management, Non-Access Stratum signaling; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, between E-UTRAN and P-GW, transmits data, and is responsible for pending datas such as paging are carried out buffer memory.P-GW then is the borde gateway of EPS and PDN (Packet Data Network, packet data network) network, and the access of being responsible for PDN reaches functions such as between EPS and PDN, transmitting data.PCRF is the "Policy and Charging Rules Function entity, and it links to each other through receiving interface Rx interface and the IP of operator (InternetProtocol, procotol) business network; Obtain business information; It links to each other with gateway device in the network through the S7/S7a/S7b/S7c interface on the other hand, is responsible for initiating the foundation that IP carries, QoS (the Quality of Service of assurance business datum; And the control of chargeing service quality).
EPS supports the intercommunication with non-3 GPP system.Realize that through the S2a/b/c interface P-GW is as the anchor point between 3GPP and non-3 GPP system with the intercommunication of non-3 GPP system.The system architecture diagram of EPS is as shown in Figure 1.Wherein non-3 GPP system is divided into the non-3GPP IP access of trusted and trustless non-3GPP IP access.The non-3GPP IP of trusted inserts and can directly be connected with P-GW through the S2a interface; Trustless non-3GPP IP inserts to be needed to link to each other with P-GW through ePDG (Evolved Packet Data Gateway, the packet data gateway of evolution), and the interface between ePDG and P-GW is S2b.
In traditional 3GPP network; Strategy and charge execution function (PCEF:Policy and chargingenforcement function; Below be also referred to as the PCEF module) exist only among the P-GW; PCRF passes through S7 interface (as shown in Figure 1) exchange message as long as be connected the control that can accomplish all functions with P-GW between PCRF and P-GW.But; After the 3GPP network provides the IWF with non-3GPP; Interface when between P-GW and S-GW is during based on PMIP (Proxy Mobile IP, proxy-mobile IP), and the funtion part of PCEF has been moved among the S-GW; Such as the binding function that carries etc., between S-GW and the PCRF through S7c interface (as shown in Figure 1) exchange message.When non-3 GPP system through between S2a/S2b interface and 3GPP system during the intercommunication access, the also function of resident part PCEF in the non-3 GPP system.When non-3 GPP system is connecting system trusty, pass through S7a interface (as shown in Figure 1) exchange message between PCRF and non-3 GPP system; When non-3 GPP system is fly-by-night connecting system, pass through S7b interface (as shown in Figure 1) exchange message between PCRF and non-3 GPP system.
When first session that is established to a certain PDN, PCEF need inquire about the IP address of PCRF, and goes registration to PCRF.When PCEF only resides in P-GW; P-GW is according to APN (Access PointName; APN) seeks IP address or the additive method that passes through configuration PCRF with the corresponding PCRF:P-GW of relevant PDN in this locality; As obtain the IP address of PCRF to DNS (DomainName Server, name server) inquiry.But, the function of PCEF can have following problem when being distributed to more than a node: how to guarantee that a plurality of PCEF find same PCRF.
Summary of the invention
The technical problem that the present invention will solve is, a kind of system of selection of policy billing control server is provided, and is applied to the grouping system of 3GPP evolution, guarantees that a plurality of PCEF find same PCRF when making the function of PCEF be distributed to more than a node.
For addressing the above problem; The present invention proposes a kind of system of selection of policy billing control server; Said policy billing control server be the PCRF entity be arranged in 3GPP evolution grouping system and the strategy comprise a PCEF module and the 2nd PCEF module that resides in different nodes with charge execution function PCEF module, the method comprising the steps of:
