In order to solve relevant issues such as above-mentioned QoS and charging, 3rd Generation Partnership Project (3rdGeneration Partnership Project, 3GPP) strategy and control (the policy andcharging Control that charges have been defined, PCC) framework can satisfy different QoS control and charging demand by this framework.
As shown in Figure 1,3GPP has two classes at the roaming scence of the PCC framework of 23.402 li definition of TS: home domain route (Home Routed) and local breakthrough (Local Breakout).Wherein, Home Routed be meant packet data gateway (Packet Data Network Gateway, P-GW) home domain PLMN (HomePLMN, HPLMN), data must be connected to service by the home domain gateway; And Local Breakout is meant that (Visited PLMN, VPLMN), data do not need by the home domain gateway P-GW, and are connected to service from the gateway in visit territory at visit territory PLMN.
In Home Routed roaming scence, gateway (Serving Gateway, S-GW) with control of visit domain policy and charging regulation function entity (Visited Policy Control and ChargingRules Function, V-PCRF) set up gateway control session between, by V-PCRF information is transmitted to home domain policy control and charging regulation function entity (Home Policy and Charging RulesFunction, H-PCRF), and the strategy that H-PCRF generates passed to S-GW, set up Gx session (being communicated with access network IP-CAN session) between P-GW and H-PCRF corresponding to IP.The information of gateway control session and Gx session is sent to H-PCRF respectively, by the H-PCRF generation strategy.Under this scene, the IP-CAN session information of P-GW does not pass through V-PCRF.
In Local Breakout roaming scence, set up gateway control session between S-GW and the V-PCRF, P-GW and V-PCRF set up Gx session (corresponding to the IP-CAN session).By V-PCRF the information of gateway control session and Gx session is handled, be transmitted to H-PCRF then, by the H-PCRF generation strategy.H-PCRF is handed down to V-PCRF with the PCC rules that generates, and V-PCRF extraction information from PCC rules generates QoS rules, and respectively PCC rules is sent to P-GW, and QoS rules is handed down to S-GW.Under this scene, gateway control session information does not need to be delivered to H-PCRF, and the IP-CAN session information of P-GW can send to V-PCRF, is handled generating the S9 session and pass to H-PCRF by V-PCRF.
As seen, under Home Routed scene, V-PCRF sets up request message to gateway control session and does not process, and also need not cooperate the IP-CAN session, receives that gateway control session sets up that directly to be transmitted to H-PCRF behind the request message just passable.And under Local Breakout scene, V-PCRF needs the IP-CAN session and participates in, and the information of processing gateway control session and IP-CAN session generates the S9 session and passes to H-PCRF by the S9 interface.
