A communication system comprises functionality for measuring call quality in connection with a user termination of a call. Specifically, a call quality estimator ( 119 ) comprises a termination processor ( 201 ) which determines a user call termination for a call. In response to the detection, a quality estimator ( 203 ) determines a termination call quality measure for a call quality at the user call termination. For example, an error rate in a time interval of duration between 10 seconds and 60 seconds before the detection of the call termination may be determined. A transmit controller ( 205 ) then transmits the termination call quality measure to a call quality processor ( 117 ). The call quality processor ( 117 ) may statistically process the termination call quality measures from a plurality of calls to evaluate performance of the cellular communication system. The correlation of the termination call quality measure with the user call termination provides for data which more accurately reflects the user perceived call quality.
