US 9,439,026 B2 · Method and system for communication between machine to machine M2M service provider networks

Abstract

Machine-to-Machine (M2M) communication has been described for communication in a single network in among others publications from the European Telecommunications Standards Institute (ETSI). The publications describe a single network with defined entities, a resource structure and protocols. According to the invention, a solution is described for communication between entities residing in different M2M networks. Entities residing in a first M2M network requiring information of an entity in another second M2M network submit a request with a target ID pointing to the entity in the second M2M network. The request is forwarded to the network node of the first network. The network node of the first network checks whether the target ID matches with an announced resource in the network node of the first network. On a match the request is routed towards the network node of the second M2M network according to an address available in a REstful structure comprising the announced resource. The network node of the second network routes the request further towards the second entity. On reception of the request the second entity processes the request and returns a reply via the path created by the previous steps.

Dependent claims

A method performed by a network node configured for operation as a first Network Services Capability Layer (NSCL) entity in a first Machine-to-Machine (M2M) Service Provider network, the method comprising:

receiving a M2M request from an M2M entity within the first M2M Service Provider network, said M2M request including a Universal Resource Identifier (URI) identifying a targeted M2M resource;
responsive to determining from the URI that the targeted M2M resource belongs to the first M2M Service Provider network, servicing the M2M request locally within the NSCL entity, or otherwise forwarding the M2M request within the first M2M Service Provider network, for servicing by another M2M entity within the first M2M Service Provider network;
and
responsive to determining from the URI that the targeted M2M resource belongs to a different, second M2M Service Provider network that is registered at the first NSCL entity, forwarding the M2M request towards a second NSCL entity of the second M2M Service Provider network.

A network node configured for operation as a first Network Services Capability Layer (NSCL) entity in a first Machine-to-Machine (M2M) Service Provider network, the network node comprising:

a communication interface circuit configured to receive a M2M request from an originating M2M entity within the first M2M Service Provider network, said M2M request including a Universal Resource Identifier (URI) identifying a targeted M2M resource;
and
a processing circuit configured to:
in response to determining from the URI that the targeted M2M resource belongs to the first M2M Service Provider network, service the M2M request locally within the NSCL entity, or otherwise forward the M2M request within the first M2M Service Provider network, for servicing by another M2M entity within the first M2M Service Provider network;
and
in response to determining from the URI that the targeted M2M resource belongs to a different, second M2M Service Provider network that is registered at the first NSCL entity, forwards the M2M request towards a second NSCL entity of the second M2M Service Provider network.
