文档介绍：、、、、Gx/(PolicyControlandCharging)指策略控制与计费,是3GPP定义的网络资源与计费策略控制架构。PCC架构主要组成部分:PCRF,PCEF,BBERF,AF,SPR,OFCS和OCS。PCRF:PolicyandChargingRulesFunctionPCEF:PolicyandChargingEnforcementFunctionBBERF:BearerBindingandEventReportingFunctionAF:ApplicationFunctionSPR:SubscriptionProfileRepositoryOFCS:OfflineChargingSystemOCS:架构Gx接口及协议栈Gx接口是GGSN/P-GW与PCRF之间的接口,基于Diameter协议进行通信。此时,GGSN/P-GW充当PCEF,A:CreditControlRequest/:Re-AuthRequest/AnswerGxc接口及协议栈Gxc接口是S-GW与PCRF之间的接口,基于Diameter协议进行通信。此时,S-GW充当BBERF,Gxc接口只有在S5/S8采用PMIP协议时才存在。A:CreditControlRequest/:Re-AuthRequest/AnswerUGW何时与PCRF交互?-功能。当满足如下条件时,UGW会与PCRF进行信令交互:1,-Switch为enable(基于APN或整机配置),功能2,用户能找到对应的PCRF(基于APN或整机配置,-Switch对应),且链路状态正常
