Performance of a channel borrowing scheme in multiservice cellular networks with reuse partitioning

The performance of a channel-borrowing scheme with different borrowing control policies in two-zone reuse partitioning in multiservice cellular networks is investigated via simulation in terms of call blocking probability and overall channel utilization. Reuse partitioning is a technique of using differing reuse factors to provide an increase in system capacity. We consider an asymmetric channel-borrowing scheme between zones in two-zone reuse partitioning and model it as a controlled Markovian queuing system and evaluate its performance via simulation. Several simulation results are presented and discussed. In this paper, we also address the problem of guaranteeing call-blocking probabilities of outer zone calls and provide a way to find the best channel borrowing control policy. Throughout the study, two classes of calls, narrowband and broadband are taken into account.
