Abstract

We propose a novel call admission control scheme to support the multiservice of cellular networks particularly under heavy loaded cell condition. The key idea of our strategy is that the services which underutilize their assigned bandwidth because of their think time are dynamically grouped and forced to share the bandwidth in round robin especially when the resource availability is unfavorable. We present the simulation results that show our proposed scheme outperforms a conventional bandwidth reconfiguration strategy in terms of call blocking probabilities.
