摘要

Process for measuring voice quality in a mobile telecommunications network, and.The measurement system of voice quality for networks of wireless telecommunications system "a process and improved measure of voice quality perceived in a network of mobile telecommunication are here.Presented.In one implementation of the invention,The process uses both radio link parameters as an objective measurement technique performed on received signals to estimate the voice quality perceived by the end user.A stage of processing of radio link extracts temporal information from a conjunction of available radio link parameters such as BER, fer, RxLev, statistics of transfer.The information of transition, and the energy of voice.Concurrently, a stage of voice processing is used to process a sequ00b3u00eancia of original signals and the received signals, obtained from the output of a telecommunications system.The sequ00b3u00eancias signal are processed by a measuring tu00e9cnia objective as a measurement of voice quality perceptual (PSQM).The outputs of the stages of the processing of link radio and voice processing stages are used to calculate an estimation for voice quality.In addition,A weight may be given to the radio link processing and voice processing in accordance with its performance under various conditions, such that the voice quality total is calculated with respect to the firstlyAct ideal.
