Abstract

This invention relates to methods and an apparatus for detecting quality induced terminations of media streams of real-time communication sessions within a packet-switched network. To enable the determination of the quality of live media streams passing by the tapping points in a network, and to use this information to determine media transmissions being aborted due to bad quality the invention evaluates quality data records of a terminated media stream to detect, whether the media stream was terminated due to bad quality or another reason. Advantageously, a threshold number of quality data records that were generated for the media stream just before termination thereof are considered in the evaluation. In case each of this threshold number of quality data records yields a bad quality of the media stream, the termination of the media stream may be judged or assumed to be induced due to bad quality.
