Priority call service on PCS networks

This paper studies the "priority call service" for personal communication s ervices such as GSM cellular networks. With this service, a priority call r equires is buffered in a waiting queue if no free channel is available. The buffered request can be served as soon as free channels become available. We develop an analytic model to evaluate the performance for the priority c all service. In addition, computer simulations are conducted to verify the analytic model. The results indicate that priority calls experience very lo w new call blocking probability, as well as low call incompletion probabili ty at the cost of increasing the force-termination probability.
