registering the another set of resources to the resources of the first machine-to-machine services capabilities layer.

5. The first network node of claim 1, wherein the operations further comprise:

receiving a request from a third machine-to-machine services capabilities layer entity implemented on a third network node to remove a set of resources available at the third machine-to-machine services capabilities layer entity, wherein the set of resources available at the third machine-to-machine services capabilities layer entity are registered in the first machine-to-machine services capabilities layer entity; and

removing the set of resources available at the third machine-to-machine services capabilities layer entity from the first machine-to-machine services capabilities layer entity.

6. The first network node of claim 1, wherein the operations further comprise:

receiving a request from a third machine-to-machine services capabilities layer entity implemented on a third network node to update a set of resources available at the third machine-to-machine services capabilities layer entity, wherein the set of resources available at the third machine-to-machine services capabilities layer entity are registered in the first machine-to-machine services capabilities layer entity; and

updating the set of resources available at the third machine-to-machine services capabilities layer entity in the first machine-to-machine services capabilities layer entity.

7. A first network node implementing a first machine-to-machine services capabilities layer entity in a communication network, the first network node comprising:

a memory comprising executable instructions; and

a processor that, when executing the executable instructions, effectuates operations comprising;

managing a first set of resources of a machine-to-machine services capabilities layer entity;

receiving a request from a second machine-to-machine services capabilities layer entity implemented on a second network node to register a second set of resources of the second machine-to-machine services capabilities layer entity, which are available at the second machine-to-machine services capabilities layer entity and which each represent a machine-to-machine services capabilities entity itself, to the first machine-to-machine services capabilities layer entity;

registering the second set of resources of the second machine-to-machine services capabilities layer entity to the first machine-to-machine services capabilities layer entity;

determining to announce the second set of resources available at the second machine-to-machine services capabilities layer entity to a third machine-to-machine services capabilities layer entity implemented on a third network node,

generating an announcement advertising the second set of resources available at the second machine-to-machine services capabilities layer entity;

transmitting the announcement to the third machine-to-machine services capabilities layer entity; and

receiving, by the first machine-to-machine services capabilities layer entity, a response from the third machine-to-machine services capabilities layer entity.

8. The first network node of claim 7, wherein the first machine-to-machine services capabilities layer entity comprises a network services capabilities layer entity operating in a first network domain and the third machine-to-machine services capabilities layer entity comprises a network services capabilities layer entity operating in a second network domain.

9. The first network node of claim 7, wherein the operations further comprise transmitting a response to the second machine-to-machine services capabilities layer entity.
