A system and method are provided for performing security functions of a
mobile station adapted to communicate via a communications network. The
mobile station comprises a receiver, a controller, and can also include a
ringer and/or a user identifying device. The ringer is capable of
generating a ringing tone. The user identifying device can generate data
identifying a user of the mobile station. The receiver is capable of
receiving at least one security message, where the at least one security
message comprises at least one security function. For example, the
security function can comprise actuating the ringer to continuously
generate the ringing tone, and/or actuating the user identifying device
to generate user-identifying data, and thereafter transmitting a status
message including the user-identifying data. The controller is therefore
capable of interpreting the at least one security message, and thereafter
performing the at least one security function.
