Abstract

The invention discloses a policy and charging control-based redirection method. In the method, correspondence between a redirection list and indication information is set. The method also comprises the following steps of: a policy control and charging rules function (PCRF) entity transmits the indication information corresponding to a redirection server to a gateway (GW) / policy and charging enforcement function (PCEF) entity when detecting that user session needs to be redirected; and the GW / PCEF determines an address of the redirection server according to the received indication information and a local redirection list and redirects the user session to be directed to a server corresponding to the address. The invention also discloses a policy and charging control-based redirection device. By using the method and the device, the redirection of the user session can be realized.

Description

technical field

[0001] The present invention relates to a redirection technology in a wireless communication system, in particular to a redirection method and device based on policy and charging control. Background technique

[0002] With the development of wireless communication systems, in the standard system of the third generation partnership project phase 7 (3GPP Release7, 3rd Generation Partnership Project Release7), the policy and charging functions are controlled by the policy and charging control (PCC, Policy and Charging Control ) structure to achieve. The PCC architecture is a functional framework that can be applied to multiple access technologies. For example, the PCC architecture can be applied to the Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network) of the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) , Global System for Mobile Communication (GSM, Global system for Mobile Communicat...
