Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
Example one
As shown in fig. 1, the present embodiment provides a technical solution: a test method for automatically detecting uplink and downlink voice comprises the following steps:
s1: short-circuit input and output pin
Before testing, the MIC on the called end is in short circuit with the SPK pin, so that uplink and downlink voice can form a loop;
s2: turning off echo suppression algorithms
After the pin in the S1 is successfully short-circuited, the echo suppression algorithm of the called terminal is turned off by the AT instruction, and the DTMF audio signal sent by the calling terminal is returned only after the echo suppression algorithm is turned off, and if the echo suppression algorithm is not turned off, the sound returned by the called terminal cannot be heard AT the calling terminal;
s3: performing voice call
The calling terminal dials the called terminal to carry out voice communication;
s4: performing a voice test
The voice sent by the calling terminal is a DTMF audio signal with user result response code detection, the reporting of the user result response code is detected at the calling terminal, the calling terminal can also hear the voice sent to the called terminal, and the normal uplink and downlink voice is verified by checking the reporting of the user result response code.
In the step S2, turning off the echo suppression algorithm includes the following steps:
s21: setting AT instruction AT + QAUMOD to be 3 AT the called end;
s22: executing the AT command in S21, the echo suppression algorithm of the called terminal may be turned off.
In step S3, when the calling end and the called end perform a voice call, after the audio signal sent by the calling end reaches the called end, because the MIC on the called end is short-circuited with the SPK pin, the audio signal will reach the MIC pin through the SPK pin on the called end, and then return to the calling end from the called end, and the calling end can hear the returned sound.
In this embodiment, the calling terminal is a calling module (EC20-a), and the called terminal is a detected module (EC 20-B).
The calling module has the function of DTMF audio signal detection, and the method for DTMF audio signal detection comprises the following steps:
s41, when DTMF audio signal returns to calling module, setting AT command AT + QTONEDET as 1;
s42: executing the AT instruction in the step A, and detecting the DTMF audio signal when the DTMF audio signal detection function of the calling module is in an open state;
s43: after detection, the calling module can obtain a user result response code, and the audio of the module to be detected can be judged to be normal by obtaining the user result response code.
The user result response code is URC;
in effect, whether the return is valid or whether the calling party is detected to have a delayed return. The DTMF audio only has sound at the called end and URC detection report only at the called end, so that the URC and returned sound sent to the calling end by the near end (the called end after short circuit) are simulated, theoretically, the normal audio of the URC is normal to verify that the uplink and downlink of the audio are normal, and the method is a detection method. In addition, the detection of the URC report for verifying the normal audio of the equipment under long-term stress can also be realized through a script.
The process of detecting the reporting of the URC through the script comprises the following steps:
s501: the calling module and the tested module respectively run a dialing end script and a receiving end script;
s502: the calling module circularly switches network modes, in a non-GSM network state, the calling module dials the tested module, the tested module is switched on, and 2S later, the calling module sends DTMF (dual tone multi frequency) tone to the tested module in an AT + VTS instruction form; in a GSM network state, the calling module sends an audio file to the tested module in an AT + QPSND instruction form after 2S;
s503: performing a voice test
After the calling module detects the URC of the correct DTMF tone, the tested module hangs up the call, otherwise, the script is stopped to keep the site.
The embodiment also verifies that the method comprises the following steps:
s601: short-circuit input and output pin
Before testing, the MIC on the called end is in short circuit with the SPK pin, so that uplink and downlink voice can form a loop;
s602: performing voice call
The calling terminal dials the called terminal to carry out voice communication;
s603: performing a voice test
No matter the voice sent by the calling end is a DTMF audio signal with user result response code detection or a common audio signal, only noise can be heard at the calling end, so that the verification work of the uplink and downlink voice cannot be carried out under the condition that an echo suppression algorithm is not closed.
This embodiment also provides a test system for automatically detecting uplink and downlink voice, including:
the short-circuit module is used for short-circuit of the MIC and the SPK pin on the module to be detected;
the algorithm closing module is used for closing the echo suppression algorithm of the module to be detected through the AT instruction;
the voice call module is used for connecting the calling module and the module to be detected and carrying out voice call;
the audio test module is used for judging the voice sent by the calling module and detecting a user result response code;
the short circuit module, the algorithm closing module and the voice call module are all electrically connected with the audio test module.
Example two
As shown in fig. 1, the present embodiment provides a technical solution: a test method for automatically detecting uplink and downlink voice comprises the following steps:
s1: short-circuit input and output pin
Before testing, the MIC on the called end is in short circuit with the SPK pin, so that uplink and downlink voice can form a loop;
s2: turning off echo suppression algorithms
After the pin in the S1 is successfully short-circuited, the echo suppression algorithm of the called terminal is turned off by the AT instruction, and the DTMF audio signal sent by the calling terminal is returned only after the echo suppression algorithm is turned off, and if the echo suppression algorithm is not turned off, the sound returned by the called terminal cannot be heard AT the calling terminal;
s3: performing voice call
The calling terminal dials the called terminal to carry out voice communication;
s4: performing a voice test
The voice sent by the calling terminal is a common audio signal, and the voice sent to the called terminal can be heard at the calling terminal, so that the normal uplink and downlink voice is verified.
In the step S2, turning off the echo suppression algorithm includes the following steps:
s21: setting AT instruction AT + QAUMOD to be 3 AT the called end;
s22: executing the AT command in S21, the echo suppression algorithm of the called terminal may be turned off.
In step S3, when the calling end and the called end perform a voice call, after the audio signal sent by the calling end reaches the called end, because the MIC on the called end is short-circuited with the SPK pin, the audio signal will reach the MIC pin through the SPK pin on the called end, and then return to the calling end from the called end, and the calling end can hear the returned sound.
In this embodiment, the calling terminal is a calling module (EC20-a), and the called terminal is a detected module (EC 20-B).
This embodiment also provides a test system for automatically detecting uplink and downlink voice, including:
the short-circuit module is used for short-circuit of the MIC and the SPK pin on the module to be detected;
the algorithm closing module is used for closing the echo suppression algorithm of the module to be detected through the AT instruction;
the voice call module is used for connecting the calling module and the module to be detected and carrying out voice call;
the audio test module is used for judging the voice sent by the calling module and detecting a user result response code;
the short circuit module, the algorithm closing module and the voice call module are all electrically connected with the audio test module.
It should be noted that, because the sound returning from the tested module is a nature of echo, and is completely eliminated by the echo suppression algorithm, there is no way to detect DTMF audio signals on the calling module, and some noise is heard by the calling module, and this problem can be solved after executing the command AT + QAUDMOD 3 on the tested module.
The echo suppression algorithm was an earlier echo control algorithm. Is a nonlinear echo cancellation based on acoustic echo suppression. It compares the level of sound intended to be played by the loudspeaker with the level of sound currently picked up by the microphone by means of a simple comparator, and if the former is above a certain threshold, it is allowed to pass to the loudspeaker, and the microphone is switched off to prevent it from picking up the sound played by the loudspeaker and causing a far-end echo. If the sound level picked up by the microphone is above a certain threshold, the loudspeaker is disabled for echo cancellation purposes.
In summary, in the test methods for automatically detecting uplink and downlink voices in the two embodiments, the MIC on the audio module of the called end is short-circuited with the SPK pin, so that the uplink and downlink voices form a loop, and then the echo suppression algorithm of the called end is closed, so that the uplink and downlink voices can be automatically detected without manual testing, thereby effectively improving the automation degree of the test process, and simultaneously helping testers to release a large amount of manual tests.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
