It is standby.As shown, the process mainly comprises the steps that
Step 101: called equipment is requested according to tone testing, by the bluetooth connection between caller device, obtains master
Cry the time difference of equipment Yu called equipment.
When it is implemented, tester can be by installing in called equipment for tone testing provided by
Test interface submits tone testing request.For example, tester " can start to survey by clicking provide in the interface entitled
The button of examination " submits tone testing request, starts tone testing, for another example, tester to trigger called equipment and caller device
Tone testing can be submitted to request by clicking the button of entitled " synchronization " that provides in the interface, tone testing is submitted to ask
It asks, to trigger the time synchronization process between calling and called equipment.Period, if had built up between caller device and called equipment
Bluetooth connection obtains the time difference of caller device and called equipment then by the bluetooth connection between caller device, if
Bluetooth connection has not been set up between caller device and called equipment, then has been called equipment and starts bluetooth mode, and it is blue to scan unlatching nearby
The equipment of tooth mode after finding the caller device, establishes bluetooth connection with the caller device, by the bluetooth connection, obtains
The time difference of caller device and called equipment.
Step 102: caller device sends call request to called equipment, establishes session with called equipment.
Specifically, caller device sends call request to called equipment according to the instruction of called equipment, builds with called equipment
Vertical session.For example, passing through the indigo plant between caller device after called equipment gets the time difference of caller device and called equipment
Tooth connects equipment for indication status of calling and sends call request to called equipment according to the instruction of called equipment, establishes meeting with called equipment

Step 103: the called equipment time current according to the time difference and called equipment, determining broadcasting for audio-frequency test data
It puts the moment, and audio-frequency test data is played to caller device by the session.Optionally, the duration which keeps is greater than the sound
The playing duration of frequency test data.
Wherein, tone testing data are built in called equipment, or the other equipment by connecting with called equipment provide.
Specifically, if tone testing data are provided by the other equipment connecting with called equipment, at this point, the microphone of called equipment
(microphone, MIC) is connect with the other equipment, so that called equipment plays language by the other equipment, to caller device
Sound test data.
Step 104: caller device records the audio data received by the call, and the audio data recorded is sent out
Give tone testing equipment.
Specifically, t3 is that caller equipment clock is worked as at the time of caller device records the audio data received by the call
The preceding time.
Step 105: tone testing equipment determines the session according to the audio data and the audio-frequency test data that receive
Quality.
Specifically, tone testing equipment uses subjective quality assessment algorithm (Perceptual Evaluation of
Speech Quality, PESQ) audio data received and the audio-frequency test data are handled, obtain the flat of the session
Equal opinion value (Mean Opinion Score, MOS), the quality of the session is determined according to obtained MOS.
In a step 101, it is called the time difference that equipment obtains caller device and called equipment by following steps: called to set
It is standby to pass through the bluetooth connection between caller device, to caller device transmission synchronization request, the response returned according to caller device
