Abstract
Abstract The method operates in a system including a switching center, a base station responsive to the switching center and a mobile communication unit responsive to the base station, and includes receiving a first message from the mobile communication unit; in response to the first message, determining whether the mobile communication unit is fraudulent; based on the determination, receiving a second message at the switching center from a dedicated fraud indicator wireline connection; and in response to the second message, terminating the wireless communication of the mobile communication unit.

Claim 1
Independent Claim
224 words
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 comprising a 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, and a 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.

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 comprising a 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, and a 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.
Claim 3
Dependent Claim
17 words
The method according to claim 1, wherein the third message utilizes an International Standard 41 (IS-41) protocol.
Claim 4
Dependent Claim
240 words
In a communication system comprising a gateway switching center, a roamer switching center in communication with the gateway switching center, a roamer base station responsive to the roamer switching center and a mobile communication unit responsive to the roamer 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 comprising a signal capture device in communication with the roamer base station, a signal identifier device responsive to the signal capture device, a service node having a controller and a switch, the controller responsive to the signal identifier device and in communication with the switch, and a dedicated wireline connection coupling the switch and the gateway switching center; receiving at the roamer 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 signal identifier device; determining whether the mobile communication unit is fraudulent; based on the determination, receiving a second message at the gateway switching center from the dedicated wireline connection identifying the mobile communication unit as fraudulent; in response to the second message, receiving a third message at the roamer switching center from the gateway switching center; and in response to the third message, terminating the communication of the mobile unit by the roamer base station.
Claim 5
Dependent Claim
240 words
In a communication system comprising a gateway switching center, a roamer switching center in communication with the gateway switching center, a roamer base station responsive to the roamer switching center and a mobile communication unit responsive to the roamer 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 comprising a signal capture device in communication with the roamer base station, a signal identifier device responsive to the signal capture device, a service node having a controller and a switch, the controller responsive to the signal identifier device and in communication with the switch, and a dedicated wireline connection coupling the switch and the gateway switching center; receiving at the roamer 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 signal identifier device; determining whether the mobile communication unit is fraudulent; based on the determination, receiving a second message at the gateway switching center from the dedicated wireline connection identifying the mobile communication unit as fraudulent; in response to the second message, receiving a third message at the roamer switching center from the gateway switching center; and in response to the third message, terminating the communication of the mobile unit by the roamer base station.
