摘要
The present invention relates to a gateway changing method performed by a machine-to-machine (M2M) gateway which communicates with at least one M2M device having a constrained capability in an M2M system that includes a first layer and a second layer, and the a device therefor, the method comprising the steps of: receiving a trigger signal for indicating a gateway change through a first layer of the M2M gateway; and transmitting, to an M2M server, a first notification for indicating the gateway change through the first layer of the M2M gateway, wherein the M2M device having the constrained capability is a device that does not have the first layer, data generated in the second layer of the M2M device having the constrained capability is managed or stored in a data structure of a tree structure by the first layer of the M2M gateway, and the data structure that includes the data is retrieved by the M2M server after the notification has been transmitted to the M2M server.
