Abstract
A method and a system for performing policy and charging control for establishing multiple packet data network (PDN) connections to a single access point name (APN) are provided. The method associates the gateway control session with the subsession in the S9 session associated with the Gx session modified by the indication of Internet Protocol connectivity access network (IP-CAN) session modification message through the PDN Connection Identifier (ID), thereby, after the relocation occurs on the bearer binding and event report function (BBERF), making the modified policy and charging control (PCC) rule be sent down to the policy and charging enforcement function (PCEF) through the associated Gx session and the modified quality of service (QoS) be sent down to the destination BBERF through the gateway control session, thereby implementing the policy and charging control when establishing multiple PDN connections to the single APN in the roaming scenario.
