Traffic congestion in mobile communication networks has been the major challenge to both the service providers and subscribers. It could be due to increased subscriber numbers along with introduction of new services by service providers. This research work comparatively analysed the traffic congestion of two leading telecommunication network providers, MTN and GLOBALCOM, around Osogbo metropolis, Osun State, Nigeria. Drive test techniques was adopted to obtain the traffic congestion audit used for benchmarking of these network providers and the various parameters involved in congestion were established. The key performance indicators (KPIs) evaluated were the call setup success rate (CSSR), call drop rate (CDR), handover success rate (HOSR), traffic channel (TCH) congestion and standalone dedicated control channel (SDCCH) congestion. The result showed that MTN had a mean value of 93.34% CSSR, 1.95% CDR, 95.28% HOSR, 2.74% TCH and 1.62% SDCCH while GLOBALCOM had mean value of 95.53% CSSR, 1.11% CDR, 92.66% HOSR, 1.40% TCH and 0.78% SDCCH, respectively. The CSSR, TCH and SDCCH of MTN and the HOSR of GLO deviates greatly from the acceptable thresholds of ≥98% CSSR, ≤2% TCH, <2% SDCCH and ≥98% HOSR recommended by the Nigerian Communication Commission. Conclusively, MTN had mean traffic congestion values slightly higher than what were experienced in GLOBALCOM.
