Comparative Analysis of Handoff Queuing Scheme for Minimizing Call Drop Due to Handoff Failure in GSM Systems.

Abstract

The continuation of an ongoing call is an important quality measurement in GSM systems. Handoff process enables a cellular system to provide such a facility by transferring an ongoing call from one Base Station to another. Different approaches have been proposed and applied in order to achieve better handoff service. In our previous paper entitled “Development of Efficient Handoff Queuing Scheme for Minimizing Call Drop Due to Handoff failure in GSM Systems”, we proposed and analyzed a scheme integrating the buffer facility to the M+G scheme to further reduce handoff failure. In this paper, we continue with the analysis of this scheme by subjecting it to comparative evaluations with some existing schemes. The simulation environment was done in MatLab.
