Description
Technical field
The present invention relates to the speech quality evaluation field, relate in particular to speech quality assessment method, terminal, server and system thereof based on the engineering test terminal.
Background technology
In GSM, the important ring that speech business is experienced as user radio, the quality of its quality evaluation is determining the service quality of whole network, affects the selection of user to operator.Along with 3G, the arrival in 4G epoch, the user will be higher also to the requirement of the whole voice service quality of network.Therefore, no matter in networking in early stage process, or in the later stage network optimization work, the assessment of voice quality and to optimize all be the hot issue that Virtual network operator must be considered.
At first, optimizing the prerequisite that promotes voice quality is that the correctly method of evaluating voice quality will be arranged.Since have directly perceived, accurately, the user experiences advantage such as directly related, MOS (Mean Opinion Score, Mean Opinion Score) point system is the voice quality measure that ITU praised highly.The MOS point system comprises that subjective MOS divides evaluation and objective MOS to divide and estimates two kinds.Subjective MOS divide estimate by ITU-T P.800 and P.830 recommendation propose, carry out the subjective sensation contrast to the raw tone sample with through the speech samples that degeneration is arranged after the system handles respectively by different people, draw the MOS branch, average at last.But in reality, let the lineup answer voice and be poor efficiency and spend huge by individual feeling evaluation voice quality.Therefore; ITU-T P.862 standard provides objective MOS to divide PESQ (the Perceptual Evaluation of Speech Quality that estimates; Voice quality perception assessment) method makes voice quality to carry out objective automation assessment through special instrument or software.
Secondly, operator need cover the speech quality evaluation of the whole network, could monitor and finds weakness zone to carry out specific aim optimization the voice quality of whole network.Usually this work is carried out by drive test.Engineering test terminal as the drive test sharp weapon is a carrier with commercial mobile phone, possesses more characteristics such as be close to the users, more portable, in other type tool of contrast aspect test and the assessment real speech capability and performance advantageous advantage is arranged.
Yet being carrier with commercial mobile phone all has following shortcoming as the speech quality evaluation at engineering test terminal:
