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
The present invention relates to the transmission of digital information, relate in particular to a kind of audio fault positioning method for telecommunication system.
Background technology
Portable terminal single-pass can occur in communication process, intermittently, problems such as echo, at present, it is more various to separate positioning means for voice fault in the mobile communication, employing is to carry out a kind of conventional means that the voice fault is separated the location from the ring method, as shown in Figure 1, after communication terminal A transmits to the dotted line among information via Fig. 1 of communication terminal B, if have the realize voice fault, then select loopback point in base station control center, promptly in this position with the direct loopback of the speech of communication terminal A, promptly at loopback point with the solid line direction loopback among information via Fig. 1, like this, just can hear oneself sound in communication terminal A through loopback after the system handles, whether tested speech occurs unusually, this test for a plurality of different loopback points, separable, the fault of navigation system, this from the ring method for mobile communication system in tangible phonetic problem, single-pass for example, serious interrupted, serious distortion etc., carrying out fault separates easily, but for the voice noise, voice are slightly interrupted, voice slight distortion etc. not really significantly " weak phonetic problem " just seem that some is unable to do what one wishes, because the speaker listens while saying, its subjective judgement power can be subjected to the influence of speech behind the loopback to a certain extent, in other words, will reduce the reliability of prior art.
Summary of the invention
The object of the present invention is to provide the high audio fault positioning method for telecommunication system of a kind of reliability, to remedy the deficiencies in the prior art.
Audio fault positioning method for telecommunication system of the present invention adopts following steps:
In A, the normal information transmission link between communication terminal, configuration information transparent transmission point;
The voice state of communication terminal when directly intersecting transparent transmission information in B, the described communication terminal of test and the net by described information transparent transmission point, that is, and the voice messaging of the communication terminal that transparent transmission same communication net is interior;
C, judge between the lane place of communication system voice fault point with respect to described information transparent transmission point according to above-mentioned voice state.
In the described steps A, when described normal information transmission link relates to the different communication terminal of same communication net, in described step B, directly intersect transparent transmission information by information transparent transmission point between the described different communication terminal;
In described steps A, when described normal information transmission link related to the different communication terminal of different communication networks, in described step B, described communication terminal directly intersected transparent transmission information with communication terminal in the net separately by described information transparent transmission point;
In the described steps A, described information transparent transmission point is processing module or corresponding veneer in the message transmission link;
In the described message transmission link,, can be divided into three kinds of processing modules for the base station control center of mobile communication system, that is, and application protocol processing module, transport module and encoding and decoding and rate adapted processing module;
Described processing module can comprise a plurality of different processing veneers according to specific implementation;
By the information of external command to the relevant voice messaging transmission of described communication systems communicate, information transparent transmission point or transparent transmission operational order;
Among the described step B, when directly intersecting transparent transmission information between the described communication terminal, transmitting terminal user's voice information directly is transferred in corresponding receiving terminal user's the passage at information transparent transmission point;
In described direct intersection transparent transmission information, for using ATM (AsynchronousTransfer Mode, asynchronous transfer mode) message transmission, adopting PVC (PermanentVirtual Channel, Permanent Virtual Path) exchanged form that voice messaging directly is crossed to corresponding user's time slot gets on; Handle for encoding and decoding and rate adapted, can directly user data be exchanged on another user resources according to the resource situation of CU; For in the E1 system, transmitting, can voice messaging be crossed on corresponding user's time slot by the Time Slot Occupancy relation of precognition;
Behind the described step C, according between the lane place of communication system voice fault point with respect to described information transparent transmission point, set new information transparent transmission point,, further dwindle the position interval range of communication system voice fault point with respect to information transparent transmission point by described step B and step C.
Beneficial effect of the present invention is: in the present invention, because the voice state when directly intersecting transparent transmission information between the test different communication terminal, just can avoid the drawback that the speaker listens while saying in the prior art, this is especially for not really significantly " weak phonetic problem ", with respect to prior art, have bigger advantage, reduce tester's self subjectivity influence as far as possible, can improve reliability and accuracy that voice state is judged greatly, efficiently and accurately location of communication system voice fault point.
