Impact of Queuing on Call Completion Rate in GSM Networks

Effective utilization of network resource reduces the probability that a call arriving at the base station (BS) of a network will be lost. Performance evaluation plays an important role in modelling and designing of effective schemes to utilize limited network resource. This objective is achieved by an accurate traffic characterization and a precise analysis of the performance metrics in terms of traffic intensity. This has prompted the deployment of various concepts and techniques aimed at delivering solutions on the issue of optimization of GSM networks. In this paper, we use the queuing approach to develop a model for call completion, making signal power considerations as well. A General User Interface (GUI) is designed for the developed model using MATLAB and the impact of queuing on call completion is analysed by carrying out an assessment of the performance of the model at different parametric values.http://dx.doi.org/10.4314/njt.v34i1.2
