Call quality test method, device and system

Abstract

The invention discloses a call quality test method, a call quality test device and a call quality test system. The call quality test method comprises the following steps of: sending double-tone multiple-frequency signals to a tested terminal; testing network call quality according to the received double-tone multiple-frequency signals returned by the tested terminal to obtain a call quality test result; and comparing the pre-stored call quality fault statistical data with the call quality test result to obtain a network call fault type. The call quality test method, the call quality test device and the call quality test system remotely and automatically test the user call quality after user network complaints, avoid manually processing the complaints, reduce the period of processing client complaints, process the call faults in time, avoid repeated complaints of clients, and acquire the fault type of the current test more precisely by comparing the test result with the historical callfault data.

Description

technical field [0001] The invention relates to a mobile communication core network technology, in particular to a call quality testing method, device and system. Background technique [0002] In the prior art, the test process after the user network throwing and dismantling process is performed manually. Accept the circulation procedure in the form of trouble work order, in order to ensure the timeliness of resolution, the conventional processing method is: the customer's online complaint is to conduct an inquiry after accepting the complaint, send someone to the complaint site for on-site testing and processing, and conduct a return visit after the complaint is completed . There is currently no good solution to complaints with long processing cycles such as remote coverage, inter-provincial roaming, and interconnection. It is necessary to send a special person to return to visit the customer and do a good job of explaining and comforting, and only strive for the understa...
