Nigeria: NCC Sets Two Percent Call Drop for Operators


Nigerian regulator NCC has set a 2 per cent call drop rate as limit that telecommunications companies must work towards as part of the condition they must meet in the new Key Performance Indicators guidelines on Quality of Service (QoS).

The NCC said in its website that there has been some improvement on the networks in terms of the level of quality of service operators deliver to their subscribers but a lot still need to be done to achieve minimum of 2 per cent call drop.

This is, however, coming in spite of the frequent dissatisfaction being expressed by telecoms subscribers on the quality of service by the operators characterised by call drops, occasional service outage and network congestion, among others.

Nearly all the service providers in the GSM and CDMA segments of the industry are adjudged to have made some improvement in the area of upgrading their networks to accommodate the subscriber base on their network as well as enhancing service delivery.

In the QoS assessment report conducted to measure the level of improvement on the networks of the operators between January and November, 2011, the Commission's verdict indicated that for most of the operators, there has been improvement towards meeting the two per cent threshold.

Under the technical standard for the KPI report, NCC set 2 per cent call drop rate and 98 per cent completion rate as threshold for GSM operators such as MTN, Globacom, Airtel and Etisalat.

Similarly, a two per cent call drop rate and a 96 per cent call completion rate is set for the CDMA operators comprising Starcomms, Multi-Links, Zoom Mobile and Visafone Communications.

Call drop rate is the number of dropped calls divided by the total number of call attempts while call completion rate is the ratio of successfully completed calls to the total number of attempted calls.

The KPI measures QoS assessment criteria such as Call Setup Success Rate, Traffic Channel Congestion, Call Drop Rate, Call Completion Rate, Standalone Dedicated Control Channel, Paging Success Rate for the operators.

On each of the indexes, a rating such as 'Improvement', 'Good', 'Poor', 'Punctuation', 'Most Steady Below the Threshold' are used to indicate operators performance.
