Description
Technical field
The present invention relates to voice quality technical field of measurement and test, and in particular to a kind of voice quality is surveyed
Method for testing, test device and user equipment.
Background technology
With the gradually popularization continued to develop with network of radio network technique, client is to network
The requirement of overall QoS of voice improve constantly, it may be said that the quality of voice quality is straight
Connect the selection for affecting user for operator.And in the prior art to voice quality quality
Test and appraisal are mainly come by mean opinion score (Mean Opinion Score, MOS) test
Realize.
In MOS, 0 point represents worst quality, and 5 points are best result.Pulse code modulation
PCM MOS is about 4.4 points.Conventional MOS method of testings are surveyed including subjectivity MOS
Examination and objective MOS tests.
Subjective MOS tests recommendation using ITU-TP.800 and P.830, by different people point
The other language material (degeneration file) for having decline to original language material and after system is handled is led
Perception feels contrast, draws MOS, finally averages.
The principle of objective MOS tests is to use subjective speech quality assessment (Perceptual
Evaluation of Speech Quality, PESQ) method will be collected by transmission link
Audio file carries out contrast evaluation and test with audio sample file, and voice is objectively evaluated so as to reach
The purpose of signal quality.The basis of objective MOS tests is exactly can be accurate by audio sample
This document plays to transmission terminal, and accurately collects audio signal from transmission terminal.
Drive test, also known as DT (Drive Test, DT), are the important compositions of radio network optimization
Part, drive test (DT) refers to by survey tool, and wireless network is carried out along specific circuit
Network parameter/operation and measure and the collection of speech quality index, its effect essentially consist in network matter
The assessment of amount and the optimization of wireless network.
In existing MOS testing schemes, there are two kinds of testing schemes.
The first is automatic road measuring testing scheme.In the headend equipment of automatic road measuring test system,
When carrying out audio call test, equipment itself carries out record/playback, enrolls degeneration file, by
Equipment carries out MOS scorings to degeneration file, and MOS score values are sent to monitoring backstage, real
Existing MOS tests.
Second of side for the special MOS boxes progress MOS tests of traditional drive test software configuration
Case.Access testing mobile phone and MOS boxes on test computer, when carrying out audio call test,
Record/playback is carried out by MOS boxes, degeneration file is enrolled, degeneration file is entered by test computer
Row MOS scores, and realizes that MOS is tested.The program need notebook computer, MOS boxes and
Testing mobile phone, which cooperates, could realize MOS tone testings, indispensable.
In existing MOS testing schemes, no matter which kind of scheme, is required for carrying corresponding
Test equipment, it has the disadvantage：
Firstly, for now more and more indoor and outdoor coverage tests for needing to walk about, existing side
Case heavier-weight, carries inconvenient, especially second scheme, also to access on computers
Testing mobile phone and MOS boxes, are carried very inconvenient.In the first scheme, in addition it is also necessary to pass through prison
Control backstage can just see the statistics of MOS values and correlation.
Secondly as exist link that multiple cable connecting links and needing set manually compared with
It is many, cause reliability poor.The especially complex operation of second scheme：Test is different
Networking needs different testing mobile phones, while to adjust the Audio Matching circuit of MOS boxes therewith
Coordinate.This point clearly proposes it in Long Term Evolution (Long Term first with China Mobile
Evolution, LTE) frequency requirement in terms of terminal：Time-division Long Term Evolution must at least be supported
(Time Division LTE, TD-LTE), FDD Long Term Evolution (Frequency
Division Duplexing LTE, FDD-LTE), global system for mobile communications (Globle
Systerm for Mobile Communications, GSM), TD SDMA (Time
Division-Synchronous Code Division Multiple Access, TD-SCDMA),
CDMA (Wideband Code Division Multiple Access, WCDMA) five
Plant after standard, become more prominent.
