Embodiment Construction

[0036] The present invention utilizes switchboard NO.7 signaling message to carry out the method for preventing telecommunication fraud, specifically comprises the following steps:

[0037] 1) Use relay high-impedance bypass or TCP\IP to connect to the signaling platform of the telecom operator, and implement the acquisition of telephone call signaling;

[0038] 2) Set the data buffer to store the IAM and ANM messages of each TS channel;

[0039] 3) Utilize the RLC message to trigger the sending mechanism, and pack the IAM, ANM and RLC messages;

[0040] 4) Utilize IAM call frequency to carry out suspicious degree analysis to above-mentioned packing message, write suspicious phone into database, make database support carry out the blacklist input and output of artificial mode simultaneously;

[0041] 5) Utilize the ANM and RLC time intervals to determine the call duration, make effective call judgments, block invalid calls, and improve efficiency;

[0042] 6) Match the calli...

Abstract

The invention discloses a method and a system for preventing telecommunication fraud by using signaling messages of a switch No.7. In the invention, the NO.7 message in the telephone call is used, so as to design the method and the device for preventing telecommunication fraud. According to the invention, through monitoring telephone call signaling on line in real time and carrying out activities such as suspiciousness analysis to the calling number in a signaling message, blacklist matching and the like, whether the calling telephone is suspicious or fraud can be determined, after users of both sides end up the call, a telephone for originating call can call an aggrieved party in time, and after the user receives the call, warning speeches can be played automatically so as to remind the user to enhance a risk awareness and put an end to further development of a fraud case. After the adoption of the invention, through concurrent precaution to cases in an on-line dynamic way, the cases are ended up, and an excellent precaution effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of telecommunications, and relates to a method and a system for preventing telecommunication fraud, in particular to a method and a system for preventing telecommunication fraud by using the No. 7 signaling message of an exchange. Background technique [0002] In recent years, with the rapid development of the financial and communication industries, false information fraud crimes have spread rapidly in China. Fraud crimes can be said to develop and spread rapidly, causing great losses to the people. [0003] At present, the main method of telecom fraud crimes is that the perpetrator pretends to be a member of the relevant national government agencies, such as the staff of the Telecommunications Bureau, the Public Security Bureau, etc., and calls the victim. Crime, intimidating and threatening to confiscate all bank deposits of the victim, defrauding the victim of remittance of funds. [0004] The perpetrat...
