Abstract :
A method for resource allocation to facilitate call admission control based on simultaneous satisfaction of packet-level and call-level QoS constraints is proposed. It is shown that the incorporation of the non-persistent traffic characteristics in the packet-level analysis increases the statistical multiplexing gain and improves the system utilization when compared to resource allocation based on the packet-level and call-level control in isolation. The method is equally applicable to fixed networks ( such as ATM networks) and cellular networks (TDMA and CDMA-based systems) with user mobility. Numerical results for both cases, demonstrating the improvement in utilization, are presented
