Evaluation of SDCCH and TCCH congestions for Mobile networks in Yenagoa-Southern Nigeria

Abstract

This work attempts to effectively compare standalone dedicated control channel and traffic control channel congestion rates against industry benchmarks and competitor networks to identify areas for improvement, sets performance targets and establish a relationship between them. Four mobile telecommunication networks operational in Yenagoa – Southern Nigeria were considered. Results obtained shows that 9mobile, Airtel and MTN performed within the regulator’s benchmark in most cases, while noting many instances where their performance fell outside the benchmark. The maximum value obtained within the period in view for SDCCH was 3.09% and it was gotten from 9mobile while the minimum value was 0.00% and it was also from 9mobile; conversely for HTTC, The maximum value obtained within the period in view was 2.49% and it was gotten from Globacom while the minimum value obtained was 0.00% and it was from 9mobile and Airtel. For Airtel, 9mobile, Globacom, and MTN, the correlation coefficients between SDCCH and TCCH were 0.13, 0.07, 0.37, and 0.62, respectively. The four networks' positive correlation coefficient values show that, in every scenario, a rise in SDCCH congestion does not result in a corresponding drop in TCCH congestion, and vice versa. As a result, the causes of the different congestions are independent of one another.
