Abstract

A wireless terminal and wireless telecommunications system are disclosed that prevent a thief of a wireless terminal from using the stolen wireless terminal to steal wireless service. A PIN is stored in the wireless terminal and the wireless terminal itself checks that a candidate PIN matches the stored PIN before the wireless terminal will initiate a call or will establish an incoming call. Thereafter, however, the user is permitted to call that telephone number or to receive a call from that telephone number without having to enter a candidate PIN again.

In the wireless telecommunications system, a PIN is stored in a subscriber database for each user. The subscriber database also contains a history list of the telephone numbers that each user has previously called or received calls from. When the user first attempts to call a telephone number from which a received call has not been established, the wireless telecommunications system requires the user to enter a candidate PIN that matches the stored PIN before the call is established. Thereafter, the user is permitted to call that telephone number or receive a call from that telephone number without having to enter a candidate PIN again. Alternatively, when the user first receives a call from a telephone number that the user has not previously called, the wireless telecommunications system requires the user to enter a candidate PIN that matches the stored PIN before the call is established. Thereafter, the user is permitted to call that telephone number or receive a call from that telephone number without having to enter a candidate PIN again.
