Voice Traffic Pattern Modelling In Communication Network In Globacom, Akure Ondo State Nigeria

摘要

In accessing the network performance and evaluating the quality of service of Global System forMobile Communication operators from the end-user point of view, Key Performance Indicators such as callsetup success rate, Handover success rate, Traffic Channel availability , Standalone dedicated control channel,Call success rate and Call drop rate are very germane. This research analyse voice traffic and the performanceof Glomobile Network in Akure metropolis using some of the above mentioned key performance indicators. Datawere collected using Glomobile network in three local government areas for a period of two and a half years.The analysis and correlation of the Key performance indicators for the Local Governments was carried out todetermine the predominant indicators on network performance. Pearson Correlation technique was used with asignificant level of 5%. Linear Regression models describing network performance in terms of the indicatorswere developed for the Local Governments. All the analysis and model were performed with the aid of MATLABR2012b and SPSS tools. The result showed that the stand alone dedicated control channel has been fullyoptimized within the three local governments as any further improvement would have no effect on the success ofa call. Other indicators needs improvement for a better performance of Glomobile Network in Akure. Callsuccess Rate in Ifedore Local Governmentis 99.13% as against the 99.99% by Nigeria CommunicationsCommission. Call Setup Success Rate in the other two Local governments have lowervalues of 97.56% and96.21% which should also be improved with Handover Failure Rate and Traffic channel availability for all theLocal Governments.
