Problems solved by technology

[0004] Due to the need for external testing equipment in the prior art, the audio isolation test is cumbersome, and the repeatability is not good. If the audio isolation test is performed on all private network terminals, it will require a lot of work, which does not meet the actual requirements. Therefore, it is not possible to test each private network terminal
In addition, the existing technology is completely manual to test the audio isolation of private network terminals, which cannot be automated, and the labor cost is huge

Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0034] This application proposes an automatic test method for audio isolation of a private network terminal, the main idea of ​​which is: based on the basic method of audio isolation test, the audio digital signal processor (ADSP) is used to simulate the input signal of the speaker and the output of the microphone by the external test equipment The operation of the signal. The private network voice service process is usually divided into uplink processing and downlink processing, among which:

[0035] The downlink processing goes through: ADSP->Codec->Speaker (ie: ADSP->codec->speaker);

[0036] The upstream processing goes through: Mic->Codec->ADSP (ie: microphone->codec->ADSP).

[0037] From the above process, it can be seen that the downlink ...

Abstract

The invention discloses a private network terminal audio isolation degree automatic test method. The method comprises the following steps: starting an uplink and downlink data processing process in anaudio digital signal processor (ADSP); in the downlink data processing process, the ADSP sends single-tone data with the set frequency to the codec according to the setting of the application processing (AP), and the single-tone data are output to the loudspeaker through the codec to be played; and the played single-tone data is picked up by the microphone to enter an uplink data processing process and is transmitted to the ADSP through the codec, and the ADSP calculates the value of the audio isolation degree and reports the value to the AP. The invention also discloses a private network terminal audio isolation degree automatic test terminal. By applying the technical scheme disclosed by the invention, the automatic test of the audio isolation of the private network terminal can be realized, and the related operation is simplified.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method for automatically testing the audio isolation of a private network terminal and the terminal. Background technique [0002] Audio isolation is a relatively important parameter of private network terminals. It mainly tests the coupling degree of the sound output by the speaker and the sound recorded by the microphone. The value directly affects the call quality of the voice service of the private network terminal. [0003] The traditional method of testing the audio isolation is: connect the external leads of the speaker and the microphone, connect the test equipment, first directly input a single tone signal to the speaker, then use the test equipment at the microphone to obtain the recorded signal, and finally calculate the audio isolation. [0004] Due to the need for external testing equipment in the prior art, the audio isolation test is cumberso...
