The existing methods for testing the voice quality of the mobile phone comprise the following two methods:
1) a tester uses a mobile phone to be tested to communicate with another mobile phone in an actual network of an external field, and then the voice quality of the communication of the mobile phone to be tested is judged through the subjective feeling of the tester.
2) The comprehensive tester is connected with the mobile phone to be tested, the comprehensive tester is equivalent to a virtual base station and is communicated with the mobile phone to be tested, so that a tester can answer preset voice data of the mobile phone to be tested or input the voice data into the mobile phone to be tested to simulate a scene that the mobile phone receives and calls.
After the test is finished, the testers subjectively compare the voice data input by the mobile phone to be tested with the voice data recorded by the mobile phone to be tested so as to evaluate the voice quality in the sending mode; the tester subjectively compares the voice data preset by the mobile phone to be tested with the voice data answered by the mobile phone to be tested so as to evaluate the voice quality in the receiving mode; or the tester subjectively compares the voice data input by the mobile phone to be tested with the voice data generated by the electroacoustic device in the mobile phone to be tested to evaluate the voice quality in the loop mode.
In the process of implementing the invention, the inventor finds that at least the following technical problems exist in the prior art:
in the first voice quality testing method, it is difficult for the actual network in the outer testing site to have only a single network mode, so the test result is affected by other network modes, and all network modes cannot be tested because of the dependence on the outer field test.
Although the second voice quality testing method can simulate various single network modes to overcome the defects of the first testing method, the price of the current comprehensive testing instrument is very expensive, and therefore, not all mobile phone manufacturers can adopt the comprehensive testing instrument to perform voice quality testing based on research and development cost.
