Description
Technical field
The present invention relates to the method for the policy and charging control of a kind of concealing visited place network topological structure in the wireless network.
Background technology
Grouping system (the EPS of 3GPP evolution; Evolved Packet System) by the UTRAN (E-UTRAN of evolution; Evolved Universal Terrestrial Radio Access Network), MME (mobile management unit, Mobility Management Entity), S-GW (gateway, ServingGateway), PDN GW (P-GW; Packet Data Network GateWay; Data network gateway), HSS (home subscriber server, Home Subscriber Server), 3GPP aaa server (3GPP authentication and authorization charging server), PCRF (Policy and Charging Rules Function; "Policy and Charging Rules Function), reaching other support nodes forms.Wherein MME is responsible for the processing of mobile management, Non-Access Stratum signaling, user's chain of command related works such as the contextual management of mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, between E-UTRAN and PDN GW, transmits data, and is responsible for pending datas such as paging are carried out buffer memory.P-GW then is the grouping system (EPS, Evolved Packet System) of 3GPP evolution and the borde gateway of PDN (Packet Data Network) network, is responsible for the access of PDN, between EPS and PDN, transmits function such as data.PCRF is the "Policy and Charging Rules Function entity, and it obtains business information through Rx interface and operator's IP operation network interface; It links to each other another side with gateway device in the network through Gx/Gxa/Gxc; Be responsible for initiating the foundation that IP carries, guarantee the QoS of business datum, and the control of chargeing.
EPS supports the intercommunication with non-3GPP network.Realize that through the S2a/b/c interface P-GW is as 3GPP and the internetwork anchor point of non-3GPP with the intercommunication of non-3GPP network.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 pass through S2a and P-GW interface; Trustless non-3GPP IP inserts to be needed to link to each other with P-GW through ePDG (Evolved Packet Data Gateway, the data gateway of evolution), and the interface between ePDG and P-GW is S2b.
In the 3GPP network before the EPS; Strategy and charge execution function (PCEF; Policy andcharging enforcement function) exist only among the P-GW, PCRF passes through Gx interface (see figure 1) exchange message as long as can accomplish policy and charging control with the P-GW interface between PCRF and P-GW.But, in the EPS system, when the interface between P-GW and S-GW during based on PMIPv6; Because the limitation of PMIPv6 agreement, can not the transmission policy charging control information, the partial function of PCEF; For example function such as bearing binding and event report has been moved among the S-GW, is called bearing binding and event reporting function (BBERF; Bearer Binding and Event Reporting Function), pass through Gxc interface (see figure 1) exchange message between S-GW and the PCRF.When intercommunication inserts between the non-3GPP connecting system of trusted is through S2a and 3GPP system, the also resident BBERF in the trusted non-3 GPP access network Central Shanxi Plain (like Fig. 1), it is through Gxa interface and PCRF exchange message.When UE roamed, the S9 interface was as the interface of home network PCRF and access zone network PCRF.For providing professional AF (Application Function, application function), UE sends the business information that is used to formulate PCC (Policy and Charging Control, the strategy and the control of chargeing) strategy to PCRF simultaneously through Rx interface.Gx, Gxa, Gxc and Rx interface all adopt Diameter.
Above PCEF, BEERF, vPCRF, hPCRF etc. can be considered functional module or entity.
When the user roams into visit ground, can use local route (Home Routed) or local break-out (LBO, Local BreakOut) dual mode to insert the PDN network.Adopt the mode of Home Routed, the user uses the P-GW of home network to insert PDN network (as shown in Figure 2); Adopt the LBO mode, the user uses the P-GW on visit ground to insert PDN network (as shown in Figure 3).When UE adopted Home Routed mode to roam, the BBERF that is positioned at access zone network carried out through vPCRF (visit PCRF) and hPCRF (home PCRF) alternately.When UE adopted the LBO mode to roam, the operator of access zone network hoped to hide the network topology structure of oneself, and promptly the BBERF of access zone network is sightless for hPCRF.VPCRF the mutual of BBERF and hPCRF that can terminate, and only transmit access zone network PCEF and hPCRF alternately.Under the roaming scence of LBO; UE inserts through E-UTRAN; S-GW and P-GW adopt PMIPv6 agreement or UE to close through the trusted non-3 GPP access network, and when adopting the PMIPv6 agreement to insert, concealing visited place network topological structure was an an open question still when specifically how implementation strategy chargeed control.
