ABSTRACT
Abstract: In this paper, we study the hand-off performance in personal communication system using splitted rating channel technique. As the number of mobile users in cellular systems increases, the user mobility becomes the dominating factor for guaranteeing quality of service. In order to support quality of service for mobile users, The rapid increase in mobile users, handoff become a major issue in mobile network. Handoff is an action of switching a call in progress in order to maintain continuity and the required quality of service of the cell when a mobile user moves from one cell coverage to another cell coverage. Here the arrival of calls in personal communication services network are modeled according to a Markov Arrival Process (MAP). Each cell of the network consists of a finite number of channels and a buffer with finite size of handoff calls. Channel exist in each cell can be used by splitting the original rate if necessary into two channels with different rates when a handoff call arrives and find all the channels busy. We construct three tractable models (1) loss model ( 2) finite capacity model (3) finite population model with integrated traffic using fixed channel assignment scheme. The purpose of our study is to improve the performance of the cellular mobile system by using directed retry scheme with splitted-rating channel technique & cut-off priority scheme. The balking and reneging behaviors of the calls have also been taken into consideration. The expression for various performance indices viz. blocking probabilities for different traffic, overall blocking probability, offered carried load etc. are determined.
