The specific embodiment

Below in conjunction with drawings and Examples the present invention is further described.

The information recording/that the present invention includes telecommunications switch and note paging system is set up the malicious call characteristic model, and intercepting system carries out the screening of malice characteristic matching and interception to magnanimity access phone. Vicious disturbance call detects and the intercepting system detection accuracy is strong and comprehensively, the investment totle drilling cost is low.

The technical solution used in the present invention is:

(1), sets up the malicious call characteristic model

By the malicious call analysis being found illegal user adopts the proper communication means that the mobile subscriber is carried out malice harassing and wrecking, certain number section user is dialed on a large scale but disconnect, employing call forwarding mode forwards the message platform to or telegraphone is swindled during client's clawback by the time; Therefore malicious call is most for not taking on the telephone, and can't adopt the ticket screening;

Because the whole province's note exhales number of users to account for 50% of the whole network calling user number in the note paging system, is about about 1,200 ten thousand. Every day, short message calling platform generated record, utilized the internal association of these a large amount of secondary user call records and call number to analyze, and accurately found the malice number.

Short message calling platform has recorded the call log during called subscriber's shutdown, this daily record detail record the information such as calling number, called number, call time. As shown in Figure 1, for the user calls the number of times statistical chart, from this statistical chart can analyze 99.99% normal users daily the amount of dialing but in call record, also exist same calling subscribe's 200-1000 time high frequency time to call out less than 200 times, to its further analysis:

Average connecting time 8s can calculate according to network, and one day normal users maximum is dialed number of times and is:

24 * 3600/8=10800 time;

At present the whole province's note exhales the user to account for the whole network user 50%, and average daily shutdown is than being 10%, maximum fall into note z z z cry and be recorded as: 10800*50%*10%=540 time

1, therefore average daily surpass this call volume because suspicious malicious call.

2, malicious call is the importing section and automatically dials, so called number is characterized as jack per line section contact number.

For this reason, inventor design draws the malicious call characteristic model and is:

A, phone are dialed the frequency high every day of the number of calls, are defined as:＞540 times/days

B, called number feature are obviously called to be consecutive number, and be defined as: the called number section is greater than 2 numbers sections; (different called number yardages/total call volume＞80% jack per line segment number code＞100);

C, possess many days continuous calling records, be defined as: continuous action＞=2 day.

If having special number to meet above feature employing, D can set up " professional white list " mode to evade.

(2), set up automatic screening and intercepting system

As shown in Figure 2, be automatic screening in the embodiment of the invention and intercepting system Organization Chart.

Utilize the note paging system to the example that malicious call screened and judged in December, 2006, China Mobile Group Jiangsu Co., Ltd has set up malicious call automatic screening and intercepting system network, as shown in Figure 3.

System to December call log screen and count the Subscriber Number that satisfies corresponding conditions and automatic output malicious call number (table one):
