We describe a mobile call admission control algorithm (M-CAC) for mobile multimedia terminals roaming within coverage areas consisting of multiple microcells. The method targets consistent soft-QoS for admitted connections with high utilization of radio resources, exploiting both temporal and spatial statistical multiplexing. We compare the performance of M-CAC to the performance of the default algorithm (all calls are accepted, provided there is enough bandwidth in the originating microcell). Results of our simulations demonstrate that a reasonably good connection-level soft-QoS can be achieved with moderate increase of cost of connections (determined by efficiency of bandwidth utilization)
