Method for terminating a wireless communication of a mobile communication unit
First Claim
1. In a communication system comprising a first switching center, a second switching center responsive to the first switching center, a second base station responsive to the second switching center and a mobile communication unit responsive to the second base station, a method for terminating a wireless communication of the mobile communication unit, comprising the steps of:
- providing a system for identifying a fraudulent mobile communication unit, the system comprisinga signal capture device in communication with the second base station,an intelligent peripheral responsive to the signal capture device,a service node responsive to the intelligent peripheral, anda dedicated wireline connection coupling the service node and the first switching center;
receiving at the base station a first message from the mobile communication unit;
determining a radio frequency signal characteristic of the mobile communication unit by the signal capture device;
receiving the radio frequency signal characteristic by the intelligent peripheral;
determining whether the mobile communication unit is fraudulent;
based on the determination, receiving a second message at the first switching center from the dedicated wireline connection, the second message identifying the mobile communication unit as fraudulent;
in response to the second message, receiving a third message at the second switching center from the first switching center; and
in response to the third message, terminating the communication of the mobile unit by the base station.
