Performance Evaluation of Handover Channel Exchange Scheme in GSM Network

Abstract

Properly designed handover procedure in cellular wireless systems are essential for maintaining continuity of a call in progress and minimizing the probability of forced termination, signaling and switching load on the network. In this research, the Handover Channel Exchange (HCE) scheme is modeled and analyzed for channels between two mobiles that are moving in opposite directions across the handover area of adjacent cells of a GSM network. The channel exchange method is interesting since it yields low values of handover failure probability as compared to the case with no channel exchange. This work compares the performance of the cellular system with and without channel exchange, using the data obtained from a GSM network, with MATLAB as the platform for the simulation and analysis. The results as presented show improvement in handover failure probability obtained by using the channel exchange as against that of no channel exchange obtained from the GSM network

“…High density areas require smaller sizes than larger sizes thus, the reason is to accommodate the large number of SUs. Large cell size often causes more blocking for two class of SUs (real and non-real-time traffic) due to the frequent hand-off from one cell to another [3]. A wellplanned handover procedure is crucial in sustaining continuity of ongoing calls.…”
