METHOD AND APPARATUS FOR POLICY MANAGEMENT IN AN INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM-BASED COMMUNICATION SYSTEM

摘要

An Internet Protocol Multimedia Subsystem (IMS)-based communication system (200) comprising multiple access networks (274, 276, 284), wherein each access network of the multiple access networks implements a different transport protocol than the other access networks of the multiple access networks, includes an application plane Quality of Service (QoS) policy server (206) that, with the support of a Quality of Service (QoS) Agent (232), coordinates and manages QoS policies across the multiple transport networks, thereby providing for centrally consistently managed QoS policies, which policy management is transport control plane and network topology agnostic.
