Abstract:
1. A method for controlling an admission of a connection in a wireless communication system between a base station and a subscriber unit, where a modulation and coding scheme of uplink and downlink communications can be varied over time, the method implemented by a Connection Admission Control module comprising steps of: receiving a request for a connection; if an available bandwidth corresponding to a current Adaptive Modulation and Coding (AMC) scheme is greater than an admission bandwidth of the connection, then admitting said connection and updating the available bandwidth; wherein the method periodically performs the following steps: evaluating if a current admission bandwidth can be changed for a plurality of active connections in view of a change in the current AMC scheme of such active connections; if said current admission bandwidth can be changed and there is not enough available bandwidth to allow the change then: if said current admission bandwidth can be changed and there is enough available bandwidth to allow the change, then updating said current admission bandwidth for said plurality of active connections and updating the available bandwidth.
