According to the embodiment of the invention, the hold-up interception method of malicious call in a kind of international business communication network at first is provided, as shown in Figure 1, comprising:
In this step, promptly the signaling platform from international business signaling collective system extracts and the signaling of setting fields match.
Below technique scheme that the embodiment of the invention is provided make a more detailed description:
The embodiment of the invention is based on existing signaling collective system and intelligent net system, set up the characteristic model (being characteristic parameter) of international business malicious call, and, introduce the interception that intelligent trigger mechanism realizes malicious call at international telephone traffic transfer point in conjunction with the high clearing world or regional information.
According to the embodiment of the invention, at first the malicious call type of present existence to be classified, primary categories is as follows:
Malicious call type one
The malicious call of telephone expenses clearing class:
This type of malicious call main forms is that caller is the first network type user, this network type user is generally normal network users, for example common domestic network user, called is the second network type user, this network type user is generally the user of international high clearing country; Perhaps,
Caller is the first network type user, this network type user is generally normal network users, for example, domestic this network users, international incoming call or his network users of moving, called is the first network type user of calling transfer to the second network type, wherein, second network type is generally the network type of high clearing country.
The notable feature of this type of malicious call promptly by the malicious call mode to extract the international settlement expense, the calling subscriber mostly is prepaid user or the general family of the IP of enterprise.
Malicious call type two
The international malicious call similar with domestic malicious call type:
1, international calling malicious call, for example, from the virtual main call number of first network type overseas (02310086,02110086,020110 etc.), call out the user of domestic second network type, the second network type user is caused harassing and wrecking, reduce user's perceptibility, influence corporate image;
2, international outgoing malicious call for example, is not purpose with the connection, induces the swindle class malicious call of called subscriber's callback etc.
In the embodiment of the invention, carried out aforesaid simple classification for the malicious call type, in the practical application, related malicious call type is more versatile and flexible, does not enumerate one by one herein.According to the technical scheme that the embodiment of the invention provides, can determine that the characteristic of correspondence parameter is to tackle by analyzing the feature of all kinds of malicious calls.
According to the embodiment of the invention,, determine the characteristic of correspondence parameter according to the feature of different malicious call types.Particularly, at different malicious call types, corresponding calling parameter comprises the number of calls and two parameters of the duration of call at least, makes a concrete analysis of as follows:
1, the number of calls in the setting-up time section:
For the second class malicious call type, for example, inveigle the malicious call of called subscriber's clawback, malicious call is most for not taking on the telephone, therefore can't adopt the ticket screening, can calculate in one day the normal users maximum according to the average connecting time of network (for example, being generally 12 seconds at present) and dial number of times and be about: 24x3600/12=7200 time, consider the otherness of international business and domestic service and value rule of thumb, generally the malicious call inspection is promptly carried out in the calling more than N1 time/day.
This characteristic parameter is the number of calls in the setting-up time section, generally the Subscriber Number that satisfies N1 time/day above calling is tackled.
2, the duration of call of per call:
According to the empirical value that all kinds of malicious calls statistics is obtained, generally to N2 second/time more than conversation check that or check day is gathered the duration of call.
Classify the communicating number that satisfies above characteristic parameter as suspicious number, according to setting the interception of strategy execution, for example, prohibit and exhale or limit and exhale then this suspicious number.In the practical application, above characteristic parameter also can only satisfy one promptly can be listed in suspicious number.
Above characteristic parameter setting can be adjusted according to network practical operation situation and malicious call type, can also more detailed characteristic parameter be set with reference to different malicious call types, to strengthen the restriction to malicious call.
As shown in Figure 2, based on above-mentioned malicious call type and characteristic parameter, in the one embodiment of the invention, the process that malicious call is tackled comprises the steps:
In this step, the keyword of setting comprises: signaling type, signaling time corresponding segment information, and the source of signaling or whereabouts, for example, extract the international side (signaling source) or state inboard (signaling whereabouts) of international office, ISUP (ISDN User Part, the ISDN(Integrated Service Digital Network) ISDNYong Hubufen) signaling (signaling type) that make a return journey and talk about in all worlds of (signaling time corresponding segment information) in the setting-up time section.
In this step, the signaling that extraction obtains is resolved, promptly according to the caller communicating number, called communicating number and the duration information that comprise in the signaling of extracting, determine that each communicating number possesses in the setting-up time section with the malicious call characteristic parameter corresponding parameters of determining, according to the parameter value of determining, determine to satisfy the communicating number of malicious call characteristic parameter; More specifically, if the malicious call characteristic parameter comprises the number of calls in the setting-up time section and the duration of call of per call, the signaling that extraction obtains is resolved, promptly the record of the call signaling in the setting-up time section is carried out tabulate statistics, determine each caller or the called number number of calls and the information such as the duration of call in this time period according to the calling number in the signaling message or called party number parameter.
In this step, in advance at dissimilar malicious calls, extract the characteristic of correspondence model, and by analyzing and the corresponding signaling of determining of communicating number, determine the feature of the calling that this communicating number produces, and mate with the characteristic model that extracts at dissimilar malicious call, determine the malicious call type of the calling correspondence that this communicating number produces according to matching result.For example:
At telephone expenses clearing class malicious call (malicious call type one), being characterized as of extraction: the international outgoing of high clearing country; At being characterized as that the international malicious call similar with domestic malicious call type (malicious call type two) extracted: call out signaling informations such as the frequency, call conversation duration and satisfy preset threshold.
