Performance analysis of some channel access schemes in cellular communication systems

The quasi-optimal maximum packing policy which gives the lowest blocking rates for dynamic channel assignment is considered. The authors formulate the stochastic model and apply an efficient approximation to compute the performance measures. The authors have previously shown that the analysis of a stochastic model of a maximum packing policy is equivalent to that of a fixed-route circuit-switched network. Thus, some of the performance measures in cellular communication systems can be obtained by using the well-developed exact simulation and approximation methods used in analyzing circuit-switched networks. Formal costs associated with each connection are used to show how dynamic channel assignment with maximum packing can improve the service and increase the total revenue. The results support an argument for the realization of the dynamic channel assignment and rearrangement in cellular communication systems
