Test system for evaluating uplink or downlink quality of multiple user devices using average opinion score (MOS)

摘要

A test system is provided to test both voice and video quality of the connection for a large number of mobile phones, tablets, laptops or other user transmit/receive devices from a central location. The quality can be expressed as a Mean Opinion Score (MOS) and the uplink and downlink connection quality can be separately estimated. The system allows the use of media fragments that are characteristic of an end user and allows video data to be measured at the time and location that the user typically makes calls.
