The 3rd generation partnership project (3GPP) selects IP multimedia subsystem (IMS) to provide multimedia services for various access networks. Work in this paper is to extend the supported access networks, such as 3GPP and wireless local area network, to worldwide interoperability for microwave access (WiMAX) on quality of service (QoS) Management. Basing on description of tight-coupled interworking network architecture of WiMAX and IMS, we put forward an end-to-end QoS management architecture called QMFA to perform QoS negotiation and policy control. The frame solves the problem of QoS connectivity and interoperability between WiMAX and IMS networks by introducing a new WiMAX bearer service management architecture (WBSMA), a Policy-based token mechanism called PQNST, and a method of mapping among WiMAX QoS, universal mobile telecommunication system (UMTS) QoS and IP QoS. At last, a simulation system is introduced to show how the frame works to guarantee the QoS management for multimedia service throughout the whole network. It proves the proposed frame can effectively reduce the jitter for real-time video-conference application.
