ABSTRACT
Mobile communication is ubiquitous and it usage cut across all sections of human activities. This service has become a necessity in the daily activities of humans across the globe; from communications within organizations, healthcare, educational institutions, government agencies, the judicially, etc, all these human driven activities rely on mobile communications for prompt information delivery. Ensuring quality service delivery by the mobile network operators (MNOs) in the mobile communication space to meet the demands the loyal users is essential. Poor quality of service in mobile communication such as call setup failures, signals loss, congestion, jitter, call drops are some of the key indicators which usually have severe effect on network quality and the experience of mobile service users. This paper investigated how the quality of mobile communications are affected by Key Performance Indicators (KPI) such as Call Setup Success Rate (CSSR), Call Drop Rate (CDR), Traffic Channel (TCH) Availability, Stand-alone Dedicated Control Channel (SDCCH), and Call Setup Time (CST). These KPIs are mostly affected by severe congestions due to several factors. The paper also evaluates and analyze these factors which causes severe congestions on the mobile call traffic, the paper also sought the views and the user perception on the quality of service delivery and then provide suggestions and recommendations on how the MNOs could improve and upgrade their infrastructure to the modern technological framework, to ensure the users always have the most efficient and quality of service delivery.
