Abstract

This invention provides a system and method for measuring the perceptual quality of service (PQoS) of a signal transmitted in a communications network. A predetermined reference signal is embedded into a signal transmitted from a communications device in the communications network, e.g., by multiplexing. The composite signal travels through the telecommunications network and is transmitted to another communications device in the communications network. The composite signal is intercepted prior to being received by the other communications device. The transmitted signal and the embedded signal are separated. The transmitted signal is transmitted to the other communications device. The separated embedded signal is forwarded to a PQoS measurement unit which compares the separated embedded signal and the predetermined reference signal to determine the PQoS of the transmitted signal.
