Abstract

An automatic activation of a roamer mobile station is implemented in a visited network home location register. Responsive to a registration attempt by the roamer mobile station a default subscriber profile is defined, and a temporary subscriber (directory) number is assigned. Arrangements are also made to insure subscriber payment for any network provided wireless telephone services. Following activation of the roamer mobile station, the default subscriber profile is downloaded for use in providing service. A timer is also started and thereafter monitored for expiration. If the timer expires before the occurrence of a wireless telephone service traffic event involving the roamer mobile station, automatic deactivation of the roamer in the home location register is implemented. In this regard, the default subscriber profile is deleted and the temporary subscriber (directory) number is returned. The billing account for any network provided wireless telephone services is also closed.

monitoring for traffic events concerning the roamer mobile station, said traffic events occurring in said wireless telephone system;

resetting the timer if a traffic event is monitored in said wireless telephone system; and
