Abstract:
1. A method of measuring the quality of a circuit-switched service transmitted on a traffic channel between a transmitter and a receiver in a cellular radio network, comprising: the transmitter transmitting user data to the receiver using data frames of the traffic channel; the transmitter omitting transmission of all data frames of the traffic channel to the receiver based on a determination that the user data are missing; the transmitter transmitting control data to the receiver using associated control channels of the traffic channel; the transmitter calculating a number of frames transmitted to the receiver on the traffic channel during a certain time period; the receiver calculating a number of all frames received and correctly decoded during that certain time period; and calculating a quality value for a service to be transmitted on the traffic channel during that certain time period by subtracting the number of frames transmitted during that certain time period from the number of frames received and correctly decoded during that certain time period divided by the number of frames transmitted during that certain time period.
