Abstract

A method and apparatus for distributed services and data in a machine-to-machine (M2M) communication network are disclosed. A network server, an M2M gateway, and M2M devices include an M2M service capability layer for supporting M2M service capabilities, respectively. Reference points may be defined for interactions between network service capability layers, between gateway service capability layers, between a gateway service capability layer and a device service capability layer of an M2M device, between M2M device applications, and/or between a network, gateway, or device service capability layer and an M2M application. The network server may be split into a control server and a data server at a service capability layer to provide service capabilities for control functions and service capabilities for data functions, respectively. The data server may be configured to interact with another data server to push or pull data or resources either directly or indirectly via the control server.

Claims

1-20. -20. (canceled)

21. An apparatus configured to support machine-to-machine (M2M) communications, the apparatus comprising a processor comprising:

a service capability layer configured to provide M2M service capabilities that provide M2M functions that are to be shared by different applications; and

an application configured to run a service logic and use the M2M service capabilities accessible via an interface,

wherein the application is configured to interact with an M2M gateway, an M2M device, and an M2M server via the M2M service capabilities, wherein the M2M server is split into an M2M control server and an M2M data server at a service capability layer to provide service capabilities for control functions and service capabilities for data functions, respectively, and the service capability layer interacts with the M2M control server and the M2M data server using separate interfaces.

22. The apparatus of claim 21 further comprising:

a resource configured to store a list of M2M data servers assigned to the apparatus.

23. The apparatus of claim 21 wherein the application is configured to interact with another entity to push or pull data or resources in a sub-tree of resources in a resource tree structure.

24. The apparatus of claim 21 further comprising a capabilities resource configured to store information for sharing M2M service capabilities with another service capability layer and each instance of the capabilities resource includes sub-resources for storing information regarding supported capabilities, capabilities shared with other service capability layers, and/or capabilities shared from other service capability layers.

25. The apparatus of claim 21 further comprising at least one of a resource for requested services, a resource for agreed services, or a resource for traffic statistics, wherein the resource for requested services describes which service types that a device or gateway service capability layer or application requests, the resource for agreed services describes which service types are approved to the device or gateway service capability layer or application, and the resource for traffic statistics is for storing traffic related measurements.

26. A method for supporting machine-to-machine (M2M) communications, the method comprising:

an M2M device registering with an M2M server, wherein the M2M device and the M2M server comprise a service capability layer for providing M2M service capabilities that provide M2M functions that are to be shared by different applications; and

the M2M device interacting with an M2M gateway or another M2M device at an application level via the M2M service capabilities, wherein the M2M server is split into an M2M control server and an M2M data server at a service capability layer to provide service capabilities for control functions and service capabilities for data functions, respectively, and the device interacts with the M2M control server and the M2M data server using separate interfaces.

27. The method of claim 26 further comprising:

the M2M device storing a list of M2M data servers assigned to the M2M device in a resource.

28. The method of claim 26 further comprising:

the M2M device interacting with another entity to push or pull data or resources in a sub-tree of resources in a resource tree structure.

29. The method of claim 26 further comprising:

storing information for sharing M2M service capabilities with another service capability layer in a capabilities resource, wherein each instance of the capabilities resource includes sub-resources for storing information regarding supported capabilities, capabilities shared with other service capability layers, and/or capabilities shared from other service capability layers.

30. The method of claim 26 wherein the M2M device comprises at least one of a resource for requested services, a resource for agreed services, or a resource for traffic statistics, wherein the resource for requested services describes which service types that a device or gateway service capability layer or application requests, the resource for agreed services describes which service types are approved to the device or gateway service capability layer or application, and the resource for traffic statistics is for storing traffic related measurements.

31. A machine-to-machine (M2M) communication network, comprising:

at least one network server configured to provide network service capabilities; and

at least one gateway configured to provide gateway service capabilities,

wherein reference points are provided at least between network service capability layers, between gateway service capability layers, between a gateway service capability layer and a device service capability layer of an M2M device, between M2M device applications, and/or between a network, gateway or device service capability layer and an M2M application.

32. The network of claim 31 wherein the network server is split into a control server and a data server at a service capability layer to provide service capabilities for control functions and service capabilities for data functions, respectively, and reference points for control functions and data functions are separately provided between network service capability layers, between gateway service capability layers, between a gateway service capability layer and a device service capability layer, between M2M device application, and/or between a network, gateway or device service capability layer and an M2M application.

33. The network of claim 32 wherein one control server is configured to control more than one data server.

34. The network of claim 32 wherein the data server is configured to interact with another data server, the gateway, or an M2M device to push or pull data or resources either directly or indirectly via the control server.

35. The network of claim 32 wherein the control server and the data server have a resource configured to store a list of registered data servers and/or control servers.

36. The network of claim 31 wherein the network server and/or the gateway have a capabilities resource configured to store information for sharing capabilities with another network server or another gateway and each instance of the capabilities resource includes sub-resources for storing information regarding supported capabilities, capabilities shared with other service capability layers, and/or capabilities shared from other service capability layers.

37. The network of claim 31 wherein the gateway is configured to share gateway service capabilities with another gateway.

38. The network of claim 32 wherein the control server is configured to receive a registration request from an M2M device, gateway, or application, obtain a status of an M2M data server, select an M2M data server for the M2M device, gateway, or application, and send a registration response including an identity of the selected M2M data server to the M2M device, gateway, or application.
