Drop Call Rate as a Measure of Availability of Radio Channels

Ms Lee Li Lian asked the Minister for Communications and Information how does IDA conclude that the drop call rate is a measure of the availability of radio channels to handle and maintain established phone calls when there have been no tests done or monitored for the availability of radio channels based on IDA's Quality of Service (QoS) standards and performance results.

Assoc Prof Dr Yaacob Ibrahim: Even if the channel is not available, the operators' network equipment will be able to register that a call was being attempted. This, together with calls that were established, goes into the calculation of IDA's call success rate under the 3G QoS standards. Availability of radio channels is more relevant to mobile operators to diagnose network congestion to further improve on their networks.
