Audio fault positioning method for telecommunication system

Abstract

The method includes following steps: a) in the transmission link between communication terminals, setting up transparently transmitting point; b) testing the sound state at the time when the transparently transmitting messages are directly crossed between the communication terminal above and the terminal in intra-network via the transparently transmitting point above; c) based on acquired sound state above, deciding the location interval of sound fault point in relation to the transparent transmitting point; when normal transmission link relates to different communication terminals in intra- network, the different communication terminal directly crosses the transparent transmitting message via the transparent transmitting point; when normal transmission link relates to different communication terminals in different network, the communication terminal directly crosses the transparent transmitting message with the communication terminal in their own network via the transparent transmitting point.

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
