METHOD AND APPARATUS FOR TRANSMITTING DATA IN POWER SAVING MODE IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and an apparatus for transmitting data in a wireless communication system are provided. A machine-to-machine (M2M) apparatus in a deregistration with context retention (DCR) mode generates an uplink (UL) data having a size which is smaller than 140 bytes, transmits a ranging request message (AAI-RNG-REQ) including the UL data to a base station, and receives from the base station a ranging response message (AAI-RNG-RSP) as a response to the ranging request message. The ranging request message comprises a ranging purpose indication field for indicating a location update for transmitting the UL data in the DCR mode. Also, the ranging response message comprises a location update response field for indicating a location update success in transmitting the UL data as a response to the ranging purpose indication field.
