Abstract

Call admission control (CAC) schemes in wireless cellular networks attempt to reduce call dropping probability possibly at the expense of increased call blocking probability. We propose using channel reassignments in a controlled manner to minimize call dropping while maintaining high spectrum utilization. Guard channels are used to control the number of reassignments. The number of guard channels is dynamically determined using reassignment frequency as feedback. A simple scheme that attempts to maintain the number of reassignments under a specified target is described. A revenue based CAC scheme is then presented which attempts to maximize income by balancing the penalty for reassignments against the reward for serviced calls. Simulation results confirm and validate the ideas discussed in this paper.
