System, method and device for testing call quality

A method of testing call quality, comprising:

• establishing a call between a tested communication device and a simulation base station;
• providing, by a testing device, a standard audio to one of the tested communication device and the simulation base station after the call is established between the tested communication device and the simulation base station;
• processing the standard audio and turning the standard audio to be a test audio by using the tested communication device during a transmission process via the call, and sending the test audio back the testing device;
• performing, by the testing device, a similarity comparison between the test audio and the standard audio to obtain a similarity comparison result wherein the similarity comparison result shows the call quality of the tested communication device;
• and
• receiving the similarity comparison result from the testing device to determine the call quality of the tested communication device.

A control device, comprising:

• a processor, and
• a non-transitory machine-readable storage medium storing machine executable instructions, wherein the machine executable instructions are executable by the processor and cause the processor to:
• control to establish a call between a tested communication device and a simulation base station, wherein a testing device provides a standard audio to one of the tested communication device and the simulation base station after the call is established between the tested communication device and the simulation base station, and the standard audio is processed by the tested communication device and is changed to be a test audio during a transmission process via the call, and the test audio is sent back to the testing device such that the testing device performs a similarity comparison between the test audio and the standard audio to obtain a similarity comparison result which shows the call quality of the tested communication device;
• and
• receive the similarity comparison result returned by the testing device to determine the call quality of the tested communication device.
