Abstract :
To support QoS guarantee and resource usage in heterogeneous access network environments more efficiently (UMTS, WIMAX, WLAN DVB-T, DVB-H), there is the challenge of automated configuration and adaptation of policies for QoS-aware applications. A policy management architecture is required, which allows interaction and adaptation of QoS policies of different actors, such as network operator, service provider and user based on common a policy repository. This paper focusses on design issues of such an architecture including adaptation procedures, management interfaces for different actors, components for policy adaptation, as well as policy repository and data bases describing the QoS information for heterogeneous access networks.
