Approximation of performance measures in cellular mobile networks with dynamic channel allocation

This paper considers large cellular mobile networks with dynamic channel allocation in which the arrival rates, holding times and handover probabilities for the different cells are identical. Such networks could model, for example, cellular networks in suburban areas. Different methods of analysing these networks are compared. These methods fall into two basic categories, those which approximate a network with a smaller finite network and those which consider the expected performance of a cell within an environment consisting of cells with identical properties. Simplifications of these methods which arise out of the reversibility of a symmetric cellular network are also discussed.
