QUALITY OF SERVICE (QOS) EVALUATION OF MOBILE NETWORK SERVICES: A CASE STUDY ON THE FEDERAL POLYTECHNIC BIDA, NIGERIA

Abstract

The requisite for an assurance of telecommunication services is imperative as it establishes the relationship between perceptions and expectations of service delivered by a service provider. Mobile networks need to be under continues monitoring and control in order to maintain and improve the performance of services. In this paper, we examine and evaluate the quality of service of mobile network operators within the Federal Polytechnic Bida campus. This evaluation was undertaken using some KPIs of mobile network services. These KPIs are: Call Setup Time (CST), Call Setup Failure Rate (CSFR), Call Dropped Rate (CDR) and Call Completion Rate (CCSR). For the purpose of this study Drive test was performed using the Mobile Station (MS) software package called MyMobileCoverage Pro (MMC Pro). The result of the study revealed that the QoS provided by mobile network operators for mobile users is not sufficient, unreliable and unsatisfactory. The study also indicated that network accessibility and network retainability in the area being considered is poor. The study presents recommendations on how to improve the QoS of mobile network operators in the campus.
