Resource Management of Mobile Communication System

Abstract

To ensure good traffic handling, channel allocation is one of the important mobile communication resources for quality of service. Usually, three types of channel allocations are widely used: fixed channel allocation, borrowing radio channels from surrounding calls and dynamic channel allocations. In this paper instead conventional channel allocation schemes, we used call admission control (CAC) scheme to combat forced termination (FT). The analytical model of traffic handling in mobile cellular network is implemented by Markov chain; hence the profile of call blocking probability of newly originating call and FT is shown against the call arrival rate and the number of channels. Finally the impact of fading parameters of wireless channel on FT is also analyzed under Rayleigh fading case
