Authorization Subsystem for WiMAX Access in a Multidomain End to End QoS Enabled Architecture

In IP end to end QoS enabled multidomain communications with guarantees and limited resources, the access control functionality is required. This paper proposes an AAA-based network authorization subsystem for granting authorized end-users access to the end to end QoS services running over the WiMAX access networks. The solution relies on the WiMAX Forum AAA Framework specification. Whereas, several QoS authorization models have been considered in the design phase, this paper focus on the functionality of the QoS assured model with no-precondition.
