Latest data from the Nigerian Communications Commission (NCC) shows that the four mobile network operators, MTN, Globacom, Airtel, and 9mobile, are meeting their Quality of Service (QoS) Key Performance Indicators (KPIs).
According to the Nationwide QoS data released by the Commission, the telcos met their KPIs between July 2022 and June 2023.
The operators’ performances are measured by the regulator based on parameters such as Call Setup Success Rate (CSSR), Drop Call Rate (DCR), and Traffic Channel Congestion (TCH CONG).
According to NCC, these QoS standards ensure that consumers continue to have access to high-quality telecommunications services by setting basic minimum quality levels for all operators.
Based on the latest report, all the mobile operators crossed the threshold of 98 per cent call setup success rate in the 12-month review period.
The Call Setup Success Rate (CSSR) is calculated by taking the number of unblocked call attempts divided by the total number of call attempts.
In terms of drop call rate (DCR), which is fixed at 1 per cent or less, all the operators performed well as they recorded less than 1 per cent drop calls in the period, according to NCC’s record.
A dropped call is a call that is prematurely terminated before being released normally by either the caller or the called party.
In terms of Traffic Channel Congestion, (Standalone Dedicated Control Channel Congestion SDCCH), all the operators also met the KPI as they all recorded less than 2 per cent congestion within the period.
The regulator’s parameter in this regard is that the congestion rate for the networks should be equal to or less than 2 per cent.
The Traffic Control Channel Congestion Rate is the probability of failure to access a traffic channel during call setup.
The technical result of operators’ quality of service may, however, be different from the reality based on subscribers’ experience in the period covered by the report and even now.
The President of the National Association of Telecoms Subscribers (NATCOMS), Mr. Deolu Ogunbajo disagreed with the regulator.
