Method and system for selecting PCEF and PCRF in a wireless communication system

摘要

A method for selecting a Policy and Charging Enforcement Function (PCEF) and a Policy and Charging Rule Function (PCRF), for monitoring members in a monitored group is provided. The method includes allocating a same group Identity (ID) for members in a monitored group, selecting a Packet Data Network Gateway (PGW)/PCEF or a PCEF for a member corresponding to the first user to access the network in the monitored group according to the group ID of the member, selecting a PCRF for the member, saving at least one of a corresponding relationship between the group ID and an Internet Protocol (IP) address of the PGW/PCEF, and a corresponding relationship between the group ID and an IP address of the PCEF, and saving at least a corresponding relationship between the group ID and an IP address of the PCRF.
