DATA TRANSMISSION METHOD IN M2M DEVICE GROUP

摘要

The present specification discloses a method for allowing M2M devices in an idle mode to perform a network reentry procedure in a wireless access network supporting machine-to-machine communication (M2M). The method comprises the steps of: receiving information related to selection of a group delegate (GD) from a base station; receiving a response to a ranging request from the base station, wherein the ranging request is transmitted by an M2M device which is selected as the GD among a plurality of M2M devices in an M2M device group, based on the information related to selection of the GD; and performing a network reentry procedure on the basis of the received response. [Reference numerals] (AA) Generate UL data; (BB) AAI-RNG-AXK(ranging status); (S110) Select a group delegate(GD); (S120) Ranging code; (S140) Network reentry procedure
