Abstract

An M2M Service Layer is expanded to access the services of third parties and exchange data with these third parties. The M2M Service Layer is then able to act as a proxy between M2M Devices and the third party services. The M2M Service Layer is able to present a single/consistent interface, or API, to the M2M Device and hide the details of the third party service provider from the M2M Device.

First claim

The invention claimed is:

1. A node comprising a processor and a memory, the node further including computer-executable instructions stored in the memory of the node which, when executed by the processor of the node, cause the node to:
create a service layer resource within a service layer of the node, wherein the service layer resource represents an external service outside of the service layer and determines a mapping of one or more parameters of the service layer resource to an Application Programming Interface (API) associated with the external service;
receive, from an application and based on a protocol associated with the service layer, a first request associated with the service layer resource; and
send, to the external service via the API of the external service, one or more second requests, the one or more second requests being generated from the first request based on the mapping,
wherein the external service is provided to the application via the service layer resource so that requests associated with the application can be communicated via the service layer.

2. The node of claim 1 , wherein the service layer is provided as a middleware service between network protocol stacks and applications.

3. The node of claim 2 , wherein the service layer is a oneM2M service layer.

4. The node of claim 3 , wherein the oneM2M service layer uses a service access enablement Common Service Function (CSF) in a Common Services Entity (CSE).

5. The node of claim 1 , wherein the service layer resource is accessed by the application via one or more protocols of the service layer.

6. The node of claim 1 , wherein the node proxies data to the external service from the service layer for the application.

7. The node of claim 1 , wherein the node receives results from the external service at the service layer and makes the results available to the application via the service layer resource.

8. The node of claim 1 , wherein the node allows discovery of external services at the service layer.

9. A method comprising:
creating a service layer resource within a service layer of the node, wherein the service layer resource represents an external service outside of the service layer and determines a mapping of one or more parameters of the service layer resource to an Application Programming Interface (API) associated with the external service;
receiving, from an application and based on a protocol associated with the service layer, a first request associated with the service layer resource; and
sending, to the external service via the API of the external service, one or more second requests, the one or more second requests being generated from the first request based on the mapping,
wherein the external service is provided to the application via the service layer resource so that requests associated with the application can be communicated via the service layer.

10. The method of claim 9 , wherein the service layer is provided as a middleware service between network protocol stacks and applications.

11. The method of claim 10 , wherein the service layer is a oneM2M service layer.

12. The method of claim 11 , wherein the oneM2M service layer uses a service access enablement Common Service Function (CSF) in a Common Services Entity (CSE).

13. The method of claim 9 , wherein the service layer resource is accessed by the application via one or more protocols of the service layer.

14. The method of claim 9 , further comprising:
proxying data to the external service from the service layer for the application.

15. The method of claim 9 , further comprising:
receiving results from the external service at the service layer; and
making the results available to the application via the service layer resource.

16. The method of claim 9 , further comprising:
allowing discovery of external services at the service layer.
