Transmission-side service quality parameter examining method for voice-over internet protocol connection between telecommunication-terminals, involves evaluating comparison result based on quality-o-service-quantitative design criteria

摘要

The method involves establishing a connection between telecommunication terminals, and feeding prestored transmission-audio data to one of the terminals in a communication network. Receiving-audio data are taped in the other terminal and the connection is automatically released. The receiving audio data are stored, and the transmission and receiving-audio data are transmitted to a comparator device. A characteristic comparison is subjected by the device based on a preset test algorithm, and the comparison result is evaluated based on a preset quality-o-service-quantitative design criteria. An independent claim is also included for a testing equipment for examining a transmission-side service quality parameter of a voice-over internet protocol connection between telecommunication-terminals in a communication network.
