Method and apparatus for location update in a wireless communication system

摘要

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.

主权项

1. A location update method performed by a machine-to-machine (M2M) device in a wireless communication system, the method comprising:
transmitting a mobility access classifier indicating a mobility access classification of the M2M device to a base station; receiving information on a reattachment zone indicating a list of base stations accessible by the M2M device from the first base station; transitioning to an idle mode; performing the location update to a second base station based on whether the M2M device is out of the attachment zone; receiving from the second base station an AAI-RNG-RSP message indicating a failure of the location update and a start of an initial network reentry; and performing the initial network reentry to the second base station.
