Abstract
The present invention relates to a method performed in a machine-to-machine (M2M) device comprising a first resource and a second resource, and an apparatus for the same. The method comprises the steps of: adding first condition information to filtering properties of the first resource; receiving, from a first entity, a request message including first information indicating an address corresponding to the second resource and second information indicating an operation to be performed in the device; and transmitting a notification message to a second entity indicated by address information set in the first resource when predetermined conditions are satisfied, wherein the predetermined conditions include (1) a condition that the second resource should correspond to a parent resource of the first resource and (2) a condition that the first condition information should include a parameter corresponding to the operation, and wherein the first resource and the second resource respectively show data structures which are uniquely addressable by using unique addresses.
