performing a location update registration process if the device-specific idle mode timer expires.

14. The method of claim 13, further comprising:

receiving one of a second message informing of a system global location update registration timer and a third message informing of a new device-specific idle mode timer during the location update registration process;

if the second message is received, applying the system global location update registration timer; and
