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...
