METHOD FOR PROVIDING AN M2M SERVICE, AND METHOD AND APPARATUS FOR M2M COMMUNICATION

摘要

Provided is a method for machine to machine (M2M) communication. An M2M device acquires an M2M group identification (MGID) and an M2M zone identification. The M2M device checks whether or not the M2M device has escaped from the M2M group zone. If the M2M device has escaped from the M2M group zone, the M2M device transmits, to a base station, an update request message which requests that the M2M group identifier be updated. The M2M device receives, from the base station, a response message as a response to the update request message.

主权项

1. A method for providing a machine to machine (M2M) service in M2M communication, by a base station, comprising the steps of:
receiving an update request message of requesting updating an M2M group identifier (MGID) from an M2M device, wherein the update request message includes an M2M group identifier and an M2M zone identifier, the M2M group identifier identifies a service flow shared by a group of M2M devices in an M2M group zone, and the M2M zone identifier identifies the M2M group zone; and transmitting a response message to the update request message to the M2M device, wherein the response message includes a service unavailability indicator that indicates whether the service flow identified by the M2M group identifier is provided in a zone indicated by the M2M zone identifier.
