Universal, requirement of the client to the voice call quality of service network is also continuously improved, and the quality of voice quality directly affects use
Selection of the family for operator.Therefore, according to the requirement of mobile communications network service quality, establish that a set of voice quality is objective to be commented
Survey method preferably to carry out quantitative analysis and assessment to voice-over-net service quality, just gradually becomes Mobile Network Operator
The critical issue that must be taken into consideration during the network optimization.Voice MOS (Mean Opinion Score, mean subjective scoring) is
A kind of widest subjective assessment method is used to obtain at present, is the voice quality standard accepted extensively, therefore no matter which kind of uses
Method carries out audio quality measurement, and measurement result must all correspond to final MOS points, finally indicate audio quality with MOS value
Quality.So-called objective MOS value evaluation method obtains corresponding MOS score by objective hardware or software, with
Measure audio quality superiority and inferiority.The range that scores is 0 to 5 points:
4.0-5.0, very well, listens clear, postpones very little, exchange is smooth；
It is 3.5-4.0, slightly worse, it listens clear, postpones small, there is a noise；
3.0-3.5, it can receive, there is certain delay, can exchange；
1.5-3.0, reluctantly, listens less clear, and exchange is repeated as many times；
It is 0-1.5, poor, it does not hear.
