ABSTRACT:
A system and method are provided by which a network operator is able to detect fraudulent use of a subscriber's terminal, regardless of whether or not the subscriber is aware of the fraudulent use of her terminal. Detecting unauthorized terminal use in a wireless network includes recording a history of terminal location and registration patterns, analyzing the recorded history of location and registration patterns of the terminal, monitoring current location and registration patterns of the terminal, and requesting clarification when a deviation between said statistical analysis of the location and registration patterns of said terminal and said current location and registration patterns of said terminal is detected.
