REALIZATION METHOD, PCRF AND AF OF NAT TECHNOLOGY IN PCC FRAME

摘要

A realization method, a PCRF and an AF of NAT technology in PCC frame. The realization method comprises: during the conversation of PCRF and PCEF, the PCRF receives the first network address of UE for conversation binding sent by the PCEF; during the conversation of the PCRF and the AF, the PCRF receives the network address related information of the UE sent by the AF, the network address related information includes multiple network addresses for indicating the network position of the UE located at; the PCRF determines the first network address is included in the multiple network addresses; the PCRF binds the conversation between the PCRF and the AF and the conversation between the PCRF and the PCEF.
