The crank call identification system disclosed by the invention can exclude normal user numbers, reduce a wrong interception rate of crank call interception and improve the identification accuracy of crank calls.
Description
Technical field
The present invention relates to communication interception field, particularly relate to a kind of harassing call recognition system based on called dispersion.
Background technology
As everyone knows, telephonic communication has incorporated the every aspect of our life.As supper-fast contact communication modes, then, harassing call also grows in intensity.Therefore, need to monitor interception in real time to harassing call.And harassing call is containing feature: call time is short; Unit interval call volume is large; Called number disperses.At present, the identifying way of harassing call: the calling number calculating the frequency excess flow threshold value made a call in setting-up time section be harassing call number but, above-mentioned this method, can Timeliness coverage harassing call number from the characteristic angle of harassing call.But for the situation that normal users frequently makes a call, if the frequency ratio that calling is initiated is higher, normal users number also can be made to be put into harassing call number, and the calling causing normal users to initiate can not successfully be set up.
Summary of the invention
The object of the present invention is to provide a kind of harassing call recognition system based on called dispersion, normal users number can be got rid of, reduce harassing call interception and elam error rate occurs, improve harassing call recognition accuracy.
The technical scheme realizing above-mentioned purpose is:
A kind of harassing call recognition system based on called dispersion, comprise the called number associative cell, caller information record cell, flow comparing unit, called dispersion computing unit, called dispersion comparing unit and the display unit that connect successively, and connect the parameter setting unit of described flow comparing unit and called dispersion comparing unit respectively, and connect the clock unit of described caller information record cell, flow comparing unit and parameter setting unit respectively, wherein:
Parameter setting unit, arranges flow threshold, called dispersion threshold value and a period of time scope;
Clock unit, according to described time range time division section;
Caller information record cell, records every bar call information that in the described time period, calling number is initiated;
Called number associative cell, adds called number in the record attribute of every bar call information;
Flow comparing unit, judges whether the call number that in the described time period, calling number is initiated is greater than described flow threshold, if be greater than, sends calculating signal;
Called dispersion computing unit, receives described calculating signal, calculates the called dispersion of the calling that described calling number is initiated;
Called dispersion comparing unit, judge whether described called dispersion is greater than described called dispersion threshold value, if be greater than, then assert that this calling number is harassing call number, otherwise do not assert that this calling number is harassing call number, result sent to described display unit to show simultaneously.
Above-mentioned based in the harassing call recognition system of called dispersion, described called dispersion refers to: the percentage of the calling sum that unduplicated called number yardage and this caller are initiated in the call information of initiation.
Above-mentioned based in the harassing call recognition system of called dispersion, the record attribute of every bar call information comprise initiate this call information calling number, initiation time and called number.
Above-mentioned based in the harassing call recognition system of called dispersion, described clock unit also sends delete instruction to described caller information record cell after having divided the time period, caller information record cell deletes the expired call information record of calling number, retains the call information record in fixed time section.
The invention has the beneficial effects as follows: the present invention, using called dispersion as criterion, can filter normal call record, avoids and lists right number in harassing call number, reduce harassing call interception and elam error rate occurs, improve harassing call recognition accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of harassing call recognition system of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, harassing call recognition system based on called dispersion of the present invention, comprise the called number associative cell 1, caller information record cell 2, flow comparing unit 3, called dispersion computing unit 4, called dispersion comparing unit 5 and the display unit 6 that connect successively, and the parameter setting unit 7 of difference connection traffic comparing unit 3 and called dispersion comparing unit 5, and connect the clock unit 8 of caller information record cell 2, flow comparing unit 3 and parameter setting unit 7 respectively, wherein:
Parameter setting unit 7 is for arranging flow threshold, called dispersion threshold value and a period of time scope, and wherein, flow refers to: the call number that in time range, calling number is initiated; Called dispersion refers to: the percentage of the calling sum that unduplicated called number yardage and this caller are initiated in the call information of initiation.
Clock unit 8 according to time range time division section, and is sending delete instruction to caller information record cell after having divided the time period, makes it delete the expired call information record of calling number, retains the call information record in fixed time section.
Every bar call information that in caller information record cell 2 recording period, calling number is initiated, called number associative cell 1 adds called number in the record attribute of every bar call information, the record attribute of every bar call information is comprised and initiates the calling number of this call information, initiation time and called number.
Flow comparing unit 3 judges whether the call number that in the time period, calling number is initiated is greater than flow threshold, if be greater than, send and calculate signal to called dispersion computing unit 4, called dispersion computing unit 4 calculates the called dispersion of the calling that calling number is initiated;
Called dispersion comparing unit 5 judges whether the called dispersion calculated is greater than called dispersion threshold value, if be greater than, then assert that this calling number is harassing call number, otherwise do not assert that this calling number is harassing call number, result sent to display unit 6 to show simultaneously.
To sum up, the present invention is to after the number of calls excess flow threshold value initiated in the time period, and then the distribution situation of called subscriber is added up, according to the percentage calculating the called number yardage/sum that makes a call that user makes a call in the monitoring period, to the user exceeding setting percentage, list crank call user in.When monitoring the period, number initiate calling overclocking time, and then calculate called dispersion to improve accuracy rate.The elam error rate of harassing call can be greatly reduced, improve the hit degree of harassing call identification.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, various conversion or modification can also be made, therefore all equivalent technical schemes also should belong to category of the present invention, should be limited by each claim.
