Since the introduction of the Global System for Mobile Communication (GSM), the telecommunication industry has experienced an exponential rise in the number of subscribers. However, all these subscribers, which are in their billions are served by limited resources that need proper management. To ensure that these resources properly serve subscribers through Mobile Network Operators, regulatory bodies, such as the Nigerian Communications Commission (NCC) established a technical Quality of Service (QoS) benchmark that needs to be adhered to by the MNOs. On this premise, this work analyzes the performance of an MNO. From this analysis, it was observed that the Traffic Channel Congestion (TCHC) showed that 6% of the dataset were outside the technical benchmark set by the NCC. The Stand-alone Dedicated Control Channel (SDCCH) congestion showed that 4.2% of the dataset were not within NCC’s benchmark. Within each Key Performance Indicator (KPI), it was observed that a couple of BTSs were pointed out for closer observation as they possessed a high probability of falling outside the set threshold. The Traffic Channel Congestion (TCHC) and Standalone Dedicated Control Channel Congestion (SDCCHC) were compared with the Call Setup Success Rate (CSSR) and Call Completion Rate (CCR), it was observed that an increase in the value of either the TCHC or the SDCCHC showed a decrease proportional to that of the selected KPIs.
