Patent ID: 8353000

Claim:
A system of network convergence policy and charging control architecture, comprising an access service network (ASN), a connectivity service network (CSN), a policy control and charging rule function (PCRF), a policy distribution function (PDF) and a policy and charging control (PCC) policy enforcement entity in a Worldwide Interoperability for Microwave Access (WiMAX) network, wherein the PCRF and the PDF are separated; the PCRF is configured to determine policy and charging control PCC rules based on quality of service (QoS) parameters authorized by a service layer and user subscription profiles, and provide the PCC rules to the PDF; the PDF is configured to serve as an interface between the PCRF and the PCC policy enforcement entity to perform information distribution; and the PCC policy enforcement entity is configured to execute a QoS control policy and charging on a service data flow in accordance with the PCC rules.
