DETERMINATION OF A QUALITY INDUCED TERMINATION RATE OF COMMUNICATION SESSIONS

摘要

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.

主权项

1. A method for detecting quality induced terminations of media streams of real-time communication sessions within a packet-switched network, the method comprising:
monitoring by a passive monitoring system a plurality of media streams, wherein monitoring comprises generating, for pre-configured time intervals, quality data records for each monitored media stream, wherein each quality data record is indicative of an estimated media stream quality of the respective media stream within the respective pre-configured time interval, and in response to detecting termination of one of the media streams, determining a quality induced termination of said one terminated media stream, in case a predetermined threshold number of the lastly generated quality data records for said one terminated media stream are indicative of an estimated media stream quality below a media stream quality threshold level.
