In a Personal Communication Service network, user mobilities and call related processes are mutually orthogonal, and together they are independent of the channel allocation outcome. We propose a Parallel Discrete Event Simulation technique which exploits model independence within the global PCS network model. Event precomputation is the result of model independence. The low percentage of blocked calls typical for PCS networks is exploited in the channel allocation simulation of precomputed events by means of an optimistic approach. Experiments with a preliminary version of the simulator were performed, and are here reported.
