Abstract
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.
Claims17
A method for a base station providing a machine to machine (M2M) service in M2M communication, the method comprising:
- receiving an update request message from an M2M device, the request message requesting update of an M2M group identifier (MGID) and including the MGID and an M2M zone identifier, the MGID identifying a service flow shared by a group of M2M devices in an M2M group zone and the M2M zone identifier identifying the M2M group zone;
- and
- transmitting a response message to the M2M device in response to the received request message, the response message including a service unavailability indicator that indicates whether the identified service flow is provided in the identified M2M group zone.
A method for an M2M device providing a machine to machine (M2M) communication, the method comprising:
- acquiring an M2M group identifier (MGID) and an M2M zone identifier, the MGID identifying a service flow shared by a group of M2M devices in an M2M group zone and the M2M zone identifier identifying the M2M group zone;
- verifying whether the M2M device leaves the M2M group zone;
- transmitting an update request message that requests update of the MGID when the M2M device leaves the M2M group zone;
- and
- receiving a response message from a base station (BS) in response to the update request message, the response message including a service unavailability indicator that indicates whether the identified service flow is provided in the identified M2M group zone.
A machine to machine (M2M) device in an M2M communication system, the device comprising:
- a radio frequency (RF) unit configured for transmitting or receiving a radio signal;
- and
- a processor operatively coupled to the RF unit, the processor configured for:
- acquiring an M2M group identifier (MGID) and an M2M zone identifier, the MGID identifying a service flow shared by a group of M2M devices in an M2M group zone and the identified M2M zone identifier identifying the M2M group zone;
- verifying whether the M2M device leaves the identified M2M group zone;
- transmitting an update request message that requests update of the MGID when the M2M device leaves the identified M2M group zone;
- and
- receiving a response message from a base station (BS) in response to the update request message, the response message including a service unavailability indicator that indicates whether the identified service flow is provided in the identified M2M group zone.
