Performance Evaluation of Mobile Network Interconnections in Nigeria

The adoption of the Interconnect Clearing Houses (ICH) in Nigeria is a long awaited development expected in the telecommunication industry. This paper presents an insight into network performance evaluation and quality of service (QoS) improvement of mobile cellular systems in Nigeria using an ICH as a case study. The components of mechanisms of analyzing and evaluating the various networks are discussed. The paper also identifies the important Key Performance Indicators (KPIs) for QoS evaluation which are used in evaluating the Mobile networks. Two assessment parameters such as Call Completion Ratio (CCR) and Answer Seizure Ration (ASR) for evaluating the traffic analysis of the networks in Nigeria are deployed. The parameters are applied on four mobile network systems in Nigeria using the general models simulated in Matlab for evaluating network performance. The result of the study shows that the QoS of mobile system in the country is not 100 % reliable and still needs to be improved upon
