The recent nationwide Quality of Service (QoS) data released by the Nigerian Communications Commission (NCC) revealed that mobile network operators, MTN, Globacom, Airtel, and 9mobile, are meeting their QoS Key Performance Indicators (KPIs).
The Nationwide QoS data released by the Commission, disclosed that 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 the data, these QoS standards ensure that consumers continue to have access to high-quality telecommunications services by setting basic minimum quality levels for all operators.
Findings of the report revealed that 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 one per cent or less, the report revealed that all the operators performed well as they recorded less than one per cent drop calls in the period. (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 two per cent congestion within the period.
The Traffic Control Channel Congestion Rate is the probability of failure to access a traffic channel during call setup. The regulator’s parameter in this regard is that the congestion rate for the networks should be equal to or less than two per cent.
