Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of number state automatic identification method based on PSTN network
And device.
Background technology
Telecommunications PSTN network (Public Switched Telephone Network, PSTN) experiences
The operation of long duration, in scale and functionally has been provided with world-class leading position, and brings for China Telecom
Huge income.PSTN network adopts circuit-switched technology, is characterized in distributing the communication of a fixed-bandwidth for communicating pair
Circuit, little with propagation delay time, real-time is good, the advantages of speech quality is stable, can meet the requirement of Speech Communication well.
Call center system is docked with telecommunications PSTN net by voice exchange, by sending/receiving signaling realization
Voice dial-up function, so as to support the realization of call center's front-end business function.Feel concerned about system in a call to dock with telecommunications PSTN
When being dialled, if dialing numbers failure, either spacing, shutdown, the line is busy or rejection, telecommunications PSTN network interface return letter
Order is just as, it is impossible to distinguish the virtual condition of number by signaling.Current solution be by identification from FXS's
Set specific frequency signal is judging the state of circuit.In China, the signal sound of specification has specific sound frequency and break-make frequency, such as
Busy tone is (450Hz, -10 ± 3dBm0,0.35s on/0.35s off), Congestion Tone is (450Hz, -10 ± 3dBm0,0.7s
On/0.7s off), number unobtainable tone be (450Hz, -10 ± 3dBm0,0.1s on/0.1soff/0.1son/0.1s off/0.1s
On/0.1s off/0.4s on/0.4soff), voice exchange can be checked numbers according to sound frequency and break-make frequency to be carried out simply
Identification, however, in addition to some metropolitan fixed network telco switch can provide standard signal sound, a lot of places
Signal sound is non-type.Therefore, such scheme cannot judge the actual telephone state of non-standard signal sound, it is impossible to know automatically
Other telephone number state, the problem for causing the utilization rate of telephone number low.

20 call and include voice in sound bank, and this includes the state voice of the states such as voice packet contains at least one spacing, the line is busy, most
Afterwards by matching module to target voice and mating of including voice, the state of target voice can be recognized.In exchange of speech layer
After identification state, by number state reporting to operation layer, operation layer does not carry out recall to the number of spacing, so as to reduce passage
Ineffective occupation；Recall is not carried out to the number of rejection, it is to avoid harassing and wrecking are produced to client；To shutdown, the line is busy, and number carries out recall, from
And number utilization rate can be improved.
Fig. 3 is refer to, in a specific embodiment, the judge module 30 is additionally operable to：
When target voice is with voice match failure is included, identification is compensated to target voice, and
Target voice after compensation identification is included voice as one be stored in sound bank.
In view of the problem of the failure speech category that includes in sound bank, in the present embodiment, can by artificial and and its
The target voice of compensation identification and matching failure, it is possible to the target voice after compensation identification is included voice as one and is stored in voice
In storehouse, to increase the species for including voice in sound bank.
Fig. 4 is refer to, in a specific embodiment, the number state automatic identification equipment based on PSTN network is also
Including：
Voice library module 40 is built, for setting up the sound bank of dialing failure.In the present embodiment, can be according to actual receipts
The state speech category of collection and set up, that is, sound bank can first learn or be stored in actual dialing failure voice, Ke Yizeng
Plus the failure voice of default sound bank, increase the reliability of voice match.
In a specific embodiment, the structure voice library module 40, specifically for：
Fail after collecting the dialing failed signaling of PSTN network return voice, and the failure voice includes spacing voice, shutdown
At least one or more than one combination in voice, the line is busy voice and rejection voice；
The failure voice that collects is classified, and
Sorted failure voice is included to sound bank.In the present embodiment, failure speech category is not limited to above
Four kinds, can also be failure voice that long-time does not connect etc..Certainly, above-mentioned when classifying to failure voice, can also be by
Frequency according to failure voice appearance is sorted to which, to improve the efficiency of voice match.
The preferred embodiments of the present invention are the foregoing is only, the scope of the claims of the present invention is not thereby limited, every at this
