<p>A method for policy and charging control includes: when a terminal accesses a Code Division Multiple Access (CDMA) system in mobile Internet Protocol (IP) mode, the anchor gateway and the Packet Data Serving Node (PDSN) both establish IP-Connectivity Access Network (IP-CAN) sessions with the Policy and Charging Rules Function (PCRF) entity; the PCRF entity relates the two IP-CAN sessions established with each other; and the PCRF entity distributes the charging policies to the charging network element which is either the PDSN or the anchor gateway. A policy and charging control system and a PCRF entity are also provided in the present invention. In the present invention, the existing policy and charging control (PCC) solution is improved and used in CDMA2000 systems, and the changes to the existing CDMA2000 system architecture are small and easy to implement.</p> |
