(270) to the receiver (264) using data frames of the traffic channel (240), means (228) for not transmitting all data frames of the traffic channel (240) to the receiver (264) when the user data (270) are missing, and means (202, 204, 228) for transmitting control data to the receiver (264) using associated control channel frames of the traffic channel (240). The transmitter (260) comprises means (228) for calculating the number of all frames transmitted to the receiver (264) on the traffic channel (240) during a certain period. The receiver (264) comprises means (224) for calculating the number of all frames received on the traffic channel (240) and decoded correctly during a certain period. The cellular radio network comprises means (234) for calculating a quality value for a service (270) to be transmitted on the traffic channel (240) during a certain period by subtracting the number of frames transmitted during said period from the number of frames received during said period, and by dividing the difference obtained by the number of frames transmitted during said period.

The invention relates to a method of measuring the quality of a service transmitted on a traffic channel between a transmitter and a receiver in a cellular radio network, and to a cellular radio network applying the method. The cellular radio network comprises a transmitter (260) and a receiver (264), which communicates with the transmitter (260) over a traffic channel (240) on which a circuit-switched service (270) is transmitted and which consists of data frames and associated control channel frames. The transmitter comprises means (202, 204, 228) for transmitting user data (270) to the receiver (264) using data frames of the traffic channel (240), means (228) for not transmitting all data frames of the traffic channel (240) to the receiver (264) when the user data (270) are missing, and means (202, 204, 228) for transmitting control data to the receiver (264) using associated control channel frames of the traffic channel (240). The transmitter (260) comprises means (228) for calculating the number of all frames transmitted to the receiver (264) on the traffic channel (240) during a certain period. The receiver (264) comprises means (224) for calculating the number of all frames received on the traffic channel (240) and decoded correctly during a certain period. The cellular radio network comprises means (234) for calculating a quality value for a service (270) to be transmitted on the traffic channel (240) during a certain period by subtracting the number of frames transmitted during said period from the number of frames received during said period, and by dividing the difference obtained by the number of frames transmitted during said period.
