Audio fault positioning method for telecommunication system

Abstract

A communication system voice fault location method involving digital information transmission, the following steps are adopted: A. in the normal information transmission link between communication terminals, set the information transparent transmission point; B. test the communication terminal and the network The voice status when the communication terminal directly crosses the transparent transmission information through the information transparent transmission point; C. Judging the position interval of the communication system voice failure point relative to the information transparent transmission point according to the above voice situation; the normal information transmission link involves the same When there are different communication terminals in the communication network, different communication terminals directly cross transparently transmit information through the information transparent transmission point; when the normal information transmission link involves different communication The above-mentioned information transparent transmission point directly intersects the transparent transmission information; the invention has strong reliability and high precision, and can effectively and accurately locate the voice failure point of the communication system.

Description

technical field [0001] The invention relates to the transmission of digital information, in particular to a voice fault location method in a communication system. Background technique [0002] The mobile terminal will have problems such as one-way communication, intermittent, echo, etc. during the call. At present, there are many methods for separating and locating voice faults in mobile communications. The self-loop method is a common method for separating and locating voice faults, such as figure 1 As shown, the information from communication terminal A to communication terminal B passes through figure 1 After the dotted line in , if a voice failure occurs, select a loopback point at the base station control center, that is, directly loop back the voice of communication terminal A at this location, that is, pass the information through the loopback point figure 1 In this way, Yu communication terminal A can hear the loopback voice after being processed by the system, and ...

[0002] The mobile terminal will have problems such as one-way communication, intermittent, echo, etc. during the call. At present, there are many methods for separating and locating voice faults in mobile communications. The self-loop method is a common method for separating and locating voice faults, such as figure 1 As shown, the information from communication terminal A to communication terminal B passes through figure 1 After the dotted line in , if a voice failure occurs, select a loopback point at the base station control center, that is, directly loop back the voice of communication terminal A at this location, that is, pass the information through the loopback point figure 1 In this way, Yu communication terminal A can hear the loopback voice after being processed by the system, and test whether the voice is abnormal. For this test of multiple different loopback points, the system can be separated and positioned. This self-loop method is very convenient for fault isolation of obvious voice problems in mobile communication systems, such as single-pass, severe intermittent, severe distortion, etc. The inconspicuous "weak voice problem" seems to be a bit incapable. Since the speaker is listening while talking, his subjective judgment will be affected by the loopback voice to a certain extent. In other words, the existing technology will be reduced. reliability
