<p>Disclosed are a method in which, when an M2M terminal transmits and receives data using an M2M Group ID (MGID) in a broadband wireless communication system which supports M2M communication, a terminal updates an allocated MGID to a new MGID to be reliable, and a terminal and base station for adopting the same. According to one embodiment disclosed in the present invention, a method for updating an identifier to allow a terminal to identify a multicast service shared by group terminals in a group zone during an idle state in a wireless access system includes the steps of: receiving a message including a parameter associated with an updated identifier from a base station; updating an identifier on the basis of the updated identifier; and allowing the base station to transmit a confirmation message for reporting that the message, including the parameter, has been received.</p> |
