A method for operating a packet-oriented communications system and for classifying a packet data stream as well as network node of a packet-oriented communication system

摘要

The present invention relates to an efficient method for operating a packet-oriented communications system and for classifying a packet data stream comprising the steps of: sensing of measured values (10) with respect to the size, the time intervals and the transmission direction of the data packets of the packet data stream, examining the measured values (15, 20, 25, 30) and, if a transmission of data packets of a similar size bidirectionally in regular short time intervals in each case only in individual sections separated by pauses data transmission takes place discontinuously, examining the time length of the individual data transmission sections, as well as the length of time of the individual pauses, determining (40), whether the time length of the data transmission sections and the time length of the pauses in each case according to predetermined reference distributions with for speech telephony characteristic parameters are statistically distributed, and if this is above a threshold value with a statistical significance is the case (45), classifying the packet data stream as a speech telephony (50).The present invention also relates to a network node of a packet-oriented communication system.
