LARGE-SCALE MEASUREMENT OF SUBJECTIVE QUALITY IN MOBILE COMMUNICATION SYSTEMS Russian patent published in 2010 - IPC H04B7/26 H04W24/00 

FIELD: information technology.

SUBSTANCE: large scale subjective signal quality measurements for a mobile radio communication system are made using several handheld radio communication test units moving at various positions in the mobile radio communication system. Each handheld test unit stores a copy of a test voice or video signal stream as does a quality control system server. An uplink subjective signal quality for each such handheld test unit is determined based on comparison of the stored test signal and the received test signal from the handheld test unit. A downlink subjective signal quality to each handheld test unit is determined in the server based on the returned test signal stream received from the handheld test unit and the stored test signal stream.

EFFECT: because the handheld units do not perform subjective quality comparison calculations, ordinary subscriber units which do not require significant extra data processing resources associated with those calculations may be used.
