Congestion and service quality improvement of mobile telephone networks in Nigeria: A review

Abstract

Telecommunications and the ability to connect and interact has become a fundamental part of how the society operates. It is now the foundation for families, communities, businesses, and governments to connect and seamlessly share information in today's digital ecosystem. Mobile telephone network enables wireless communication using devices which include mobile phones, smart tablets. The mobile telephone networks provide the necessary infrastructure which are operated by service providers. The networks are usually not without congestion which is caused by a number of factors, including traffic build-up during peak periods and at hot spots, insufficient network dimensioning, especially in the switching system, and network operators' advertising offers. The consequence of network congestion is that an increase in offered load leads to either a small increase in network throughput or even a decrease in the throughput. In this work, congestion of mobile telephone networks has thus been reviewed. Improvement of Quality of Service (QoS) has also been examined. The congestion as a results of irregularity of public power supply, terminal breakdown, etc. are given sufficient considerations, while inadequate dimensioning of the network, particularly the switching and base station system and transmission impairment are not being adequately considered.
