Method, system and signal generator for determining the quality of an IP network connection

摘要

The method involves producing a measuring signal i.e. artificial voice-over Internet protocol (VoIP) call, for measuring a quality of an Internet protocol network connection by a call-generator (1). The quality of the produced measuring signal is determined by the call-generator. The measuring signal and associated quality information are simultaneously transmitted to another call-generator (2) over the Internet protocol network connection, where information, which describes an exact time and a type of noise, is determined as the quality information. Independent claims are also included for the following: (1) a system for determining quality of an Internet protocol (IP) network connection (2) a device for receiving and evaluating a measuring signal and associated quality information transmitted over an Internet protocol (IP) network connection.
