Finite population cellular radio system with directed retry

摘要

This paper prepossess an analytically tractable model to predict the performance of cellular communication nonhomogeneous traffic originated form finite population in cellular radio system. In many locations in cellular radio network, there is overlapping coverage, usually by nearly base stains. This coverage can be shared by mobile users of more than one base station (BS) to improve he telegraphic performance characteristics. We study directed retry assignment scheme which allows a call to access the neighboring BS inj case it cannot be served by he BS in which it is located. Various system performance measures viz. blocking probabilities for different traffics, overall blocking probability and offered carried load are determined. Analytical results are compared with simulations to verify he validity of he proposed algorithm. It is shown that by increasing overlapping coverage area, a substantial improvement can be achieved.
