Problems solved by technology

[0003] In the above-mentioned fault location method, since the cell with a voice call fault can only be determined according to the user complaint, it can locate the voice call fault in the cell complained by the user. Cells with call failures are manually checked, which reduces the efficiency of voice call quality detection

Embodiment approach 1

[0064] Embodiment 1: Use a single user terminal to detect the voice call quality in a single area

[0065] In this application scenario, for any cell to be tested, the voice call quality detection device assigns a voice call quality test number to the user terminal located in the cell to be tested, and the user terminal dials the test number as the calling party, and passes through the base station Establish a voice connection with the core network equipment and the call center. After the voice call ends, the user terminal or the call center reports the call recording to the voice call quality detection device. The voice call quality detection device uses the MOS algorithm to evaluate the voice recording. Judging whether the evaluation result exceeds the preset threshold, if not, it can be determined that the uplink from the user terminal to the base station and / or the wired link between the base station and the core network equipment is faulty.

Embodiment approach 2

[0069] Embodiment 2: Using two user terminals to detect the voice call quality in two areas

[0070] This implementation can generally be applied to the following application scenarios. For example, according to user complaints, when user terminal A in area A conducts a voice call with user terminal B in area B, there is a voice call quality problem. In this case, since it is impossible to determine whether there is a voice call fault in area A or area B, the voice call quality detection device can assign a voice call quality test number to user terminal A and user terminal B respectively, and user terminal A and Each user terminal B completes the voice call with the call center by using the voice call quality test number assigned to it. The center reports to the voice call quality detection device. The voice call recording between user terminal B and the call center can be reported by user terminal B or the call center to the voice call quality detection device. Voice call r...

Abstract

The invention discloses a voice call quality detecting method, device and system, and aims at improving the efficiency of voice call quality detection. The method comprises that a specific voice call quality test number is allocated to a user terminal positioned in a to-be-detected voice call quality area; voice call quality information after that the user terminal completes a voice call with the voice call quality test number is obtained; and a link with a voice call fault is determined according to the obtained voice call quality information.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and system for detecting voice call quality. Background technique [0002] In the prior art, in order to quickly locate the cause of the voice call quality problem complained by the user, the following methods are usually used to locate the fault in order to quickly locate the cause of the voice call quality problem complained by the user, such as dual no-communication, single-pass, intermittent call, noise during the call, etc.: Carry out fixed-point testing at the location designated by the complaint to see if there is any voice call quality problem reported by the user, record the information of the cell occupied by the test, and check the hardware failure alarm, call quality and other indicators of the cell in the background to determine whether there is a problem with the cell. [0003] In the above-mentioned fault location method, sin...
