Abstract
The present invention discloses a method for selecting a policy and charging rules function server in a non-roaming scenario to achieve that the PCC policies for each IP-CAN session are determined only by one PCRF. The method comprises of a Diameter Routing Agent (DRA) establishing an association relationship table in which IP Connectivity Access Network (IP-CAN) session information and corresponding address information of a Policy and Charging Rules Function (PCRF) server are stored; and when a Policy and Charging Enforcement Function (PCEF) entity and a Gateway Control Function Entity (GWCF) requests the PCRF for or to update a Policy and Charging Control (PCC) policy of one IP-CAN session, or when an Application Function (AF) entity sends application information or service information down to the PCRF, obtaining the address information of the PCRF associated with said IP-CAN session from said DRA, then performing subsequent processing.
