Channel allocation policy in cellular radio network

A channel allocation scheme for voice and data traffic on microcellular system of wireless PCS network is presented. We develop a queueing model with cutoff priority according to which handover voice/data attempts are given priority over new attempts by reserving some channels called tough channels for handoff traffic. There is provision of subrating of guard channels to serve more handover voice calls to reduce the blocking of handoff voice calls in progress. Due to non-uniform and unpredicted nature of traffic, the allocation of channels in a cluster of microcells is suggested using performance metrics such as blocking probabilities of new/handoff calls in progress and carried load etc. Furthermore some other performance results are examined to check the efficiency of the proposed algorithm. Numerical experiment is performed to demonstrate the validity of the scheme.
