ABSTRACT:
Unauthorized use of a communication unit 102 in a wireless communication system 100 may be prevented by determining the location of the communication unit 102 each time it transmits an affiliation request or a service request. Knowing the location of the communication unit 102, the controller 101 can determine whether the location of the unit fits within a historical location pattern for that unit. If the location does not fit within the pattern, the controller 101 can deny the request or send an indication to a system manager 110 asking the system manager 110 to decide what should be done with this unit.
