Analysis and Evaluation of Intercell Vertical Handoff for 4G Networks using NCC Key Performance Indicators

Abstract

This work presents a cogent framework to inspect the performance of a network call handoff based on Nigerian Communications Commission (NCC) key performance indicators for 4G. To quantify the performance of a network handoff, the call setup success rate and handover success rate were used to analyze the network performance. The ever-increasing demand for handoff decisions on mobile communication network especially as the volume of the network users increase leads to this work. The traditional means where the handoff is performed on the basis of the evaluation of signal strength are not enough. They do not take into consideration various mobile users attachment options such as the current context or the attachment of the user option. The mathematical model for the mean Call Setup Success Rate (CSSR) and mean Handover Success Rate (HOSR) were adopted to evaluate the network handoff performance. The probability threshold interval medium is assigned to characterize the defect in vertical handoff decisions that is made under uncertain information conditions. The accuracy of vertical handoff decisions which is based totally on the CSSR and HOSR were evaluated. These was done by benchmarking with NCC key performance indicators for 4G network and the evaluation was carried out using Microsoft Excel. These analytical results are applied to examine the performance of the vertical handoff model between any two base transceiver stations. Finally, we recommend an improved performance of the HOSR and CSSR in order to enhance the call handoff of a network.
