Teletraffic performance of microcellular personal communication networks

Teletraffic performance of a personal communication network (PCN) based on city street microcells catering for pedestrian mobile users is analysed. A teletraffic analysis is performed to determine the new and handover call rates as well as the channel holding time of the PCN. Next, a teletraffic model is established to determine the teletraffic performance parameters, such as the blocking probabilities of new and handover calls, the overall grade of service, the carried traffic, the channel utilisation, and the spectrum efficiency. Techniques to reduce the premature termination of calls in progress are proposed and modelled. A large spectral efficiency of 1000 Erlang/MHz/km ² is achieved at nominal blocking probability of 2%, while the probability of premature termination is reduced to less than 10 ^-4 in the presence of high call rates in excess of 0.06 calls/s/microcell.<>
