A node of a first machine-to-machine service provider, M2M SP, is provided. The node of the first M2M SP communicates with a gateway node and a node of a second M2M SP. At least one communication interface configured to receive, from the gateway node, a register message for registering a service capability layer, SCL, of the gateway node with the second NSCL. A processor configured to transmit the register message to the second NSCL and receive a response indicating whether the second NSCL registered the SCL. If the second NSCL registered the SCL, generating a resource instructing the node of the first M2M SP to proxy traffic of the SCL.
