The study presents a determination of traffic load and traffic performance parameters (indicators) in mobile communication network, using Nigeria (Lagos) as a case study. The operation and maintenance unit which is in-built with the mobile communication network was used as a measuring device. The traffic data obtained from the mobile network are; number of complete call, number of calls attempts and service time (calls duration) for the period of one year. These traffic parameters was used to determine the offered traffic, block traffic (loss traffic) and other traffic performance parameters also called Traffic Key Performance Indicator (KPI). They are Calls Completion Rate (CCR), Busy Hour Call Attempt (BHCA), Grade of Service (GOS) and Channels Utilization Percentage (CUP). It was discovered that route 9 and 10 Call Completion Rate (CCR) was not in accordance with Nigeria Communication Commission (NCC, 2008) regulation. The Grade of Service (GOS) of route 7, 8, 9, 10, 11, 12, 13 and 18 are not in accordance with NCC regulation. Also, the channel utilization percentage is above 60% stated by NCC. These will result in loss of calls or block calls in affected routes. Effort should be made by operators to provide good quality of service (QOS) and monitoring agency (NCC) should ensure that they conform to recommended standard to avoid block calls during the busy hour. © Maxwell Scientific Organization, 2012.
