In a machine to machine (M2M) system, an M2M node is identified by a first machine identification, the first machine identification being specific to an underlying communication network via which the M2M node is communicatively accessible, and a second machine identification, the second machine identification being specific to an M2M application layer by which other M2M application layer entities can communicate with the M2M node. A mapping between the first machine identification and the second machine identification is used for facilitating communication with and triggering of the M2M node. |
