Problems solved by technology

[0005] The process of information exchange between the PDN GW and the PCRF to obtain the policy control information of the IP access session does not pass through the access gateway, so that the access gateway cannot obtain the policy control information of the IP access session
Since the access gateway cannot obtain the IP access session policy control information, it cannot perform policy and charging control on the service data between the terminal and the packet data network

Abstract

The invention discloses a method for acquiring IP access conversation strategy control information, which comprises: receiving strategy control requesting information; acquiring access gateway address and message data gateway address; acquiring the IP access conversation strategy control information requested by the strategy control requesting information; sending the IP access conversation strategy control information to the message data gateway according to the message data gateway address; and sending the IP access conversation strategy control information to the access gateway according to the access gateway address. Using the method provided by the technical scheme can enable the access gateway to acquire the IP access conversation strategy control information.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, related equipment and a system for acquiring IP access session policy control information. Background technique [0002] The third generation mobile communication system architecture evolution network such as figure 1 shown. The access network accesses the Packet Data Network Gateway (PDN GW) through the S2a / b / c interface to access the Packet Data Network (PDN), wherein the S2c interface can be used for any access network, including: non- 3GPP and 3GPP. Among them, the DS-MIPv6 protocol is adopted to realize the mobility management, and the PDN GW is used as the home mobile IP agent (Home Agent, HA). The policy and charging rule function entity (Policy and Charging RuleFunction, PCRF) formulates policy and charging rules for each service data flow, so as to control the policy and charging of service data from the terminal (UE). The PDN GW in the core network ...
