Abstract
Provided are a method and apparatus for location update in a wireless communication system. A machine-to-machine (M2M) device transmits a mobility access classifier indicating the mobility access classification of the M2M device to a first base station, and receives information on a reattachment zone indicating a list of base stations accessible by the M2M device from the first station. The M2M device transits to an idle mode, and provides a location update to a second base station based on whether or not the second M2M device has exited the reattachment zone.
