Abstract

The invention provides a method and a system for sending out PCC (program-controlled computer) strategy information. The service information provided to PCRF (policy and charging rules function) by AF (audio frequency) for making PCC rule is based on the converted IP (internet protocol) address and port number in an external grouping network, namely when a network address translation function entity is arranged, the PCRF acquires the address information of service strategy information which is not translated according to a NAT (network address translation) corresponding table generated by the network address translation function entity, performs the relevance and strategy decision for the service PCC strategy according to the address information of service strategy information which is not translated, and executes the PCC strategy rule supplying process to send the PCC rule to the PCEF (policy and charging enforcement function). By the using of the method and system, the PCRF correct relevance service strategy information is ensured and the PCC strategy rule is sent to the corresponding PCEF.

Description

technical field [0001] The present invention relates to the evolved packet system (EPS, Evolved Packet System) technology of the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), in particular to a strategy and charging control (PCC , Policy and Charging Control) policy information method and system. Background technique [0002] figure 1 A schematic diagram of the composition architecture of the evolved packet system (EPS, Evolved Packet System) for the existing 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project), such as figure 1 As shown, it mainly includes Evolved Universal Terrestrial Radio Access Network (E-UTRAN, Evolved Universal Terrestrial Radio Access Network), Mobility Management Unit (MME, Mobility Management Entity), Serving Gateway (S-GW, Serving Gateway), packet Data Network Gateway (P-GW, Packet Data Network Gateway, also known as PDN GW), Home Subscriber Server (HSS, Home Subscriber Server), Policy an...
