Analysis of Drop Call Probability in Well Established Cellular Networks In Asaba, Delta State, Nigeria.
Technology in Africa has increased over the past decade. The increase in modern cellular networks requires stringent quality of service (QoS). Drop call probability is one of the most important indices of QoS evaluation in a large scale well-established cellular network. In this work we started from an accurate statistical analysis of real data collected from one of the leading telecommunication companies in Nigeria. We analysed the total percentage drop call for six cells located in Asaba, Nigeria. Our result show a lognormal distribution with σ=5x10-5, m=7,θ=0.65, and with a mean square error (MSE) of 2.133 x 10-5 for the total drop calls. The drop calls due to other factors was found to exceed that due to handover except for cell two. The obtained results can allow the network provider to optimize system performance, forecast, and improve quality of service and revenue.
