MODELING PCS NETWORKS UNDER GENERAL CALL HOLDING TIME AND CELL RESIDENCE TIME DISTRIBUTIONS

In a personal communication service (PCS) network, the call completion probability and the effective call holding times for both complete an d incomplete calls are central parameters in the network cost/performa nce evaluation, These quantities will depend on the distributions of c all holding times and cell residence times, The classical assumptions made in the past that call holding times and cell residence times are exponentially distributed are not appropriate for the emerging PCS net works, This paper presents some systematic results on the probability of call completion and the effective call holding time distributions f or complete and incomplete calls with general cell residence times and call holding times distributed with various distributions such as Gam ma, Erlang, hyperexponential, hyper-Erlaug, and other staged distribut ions, These results provide a set of alternatives for PCS network mode ling, which can be chosen to accommodate the measured data from PCS fi eld trials, The application of these results in billing rate planning is also discussed.
