Abstract

A computing device is disclosed. The computing device comprises processing circuitry that is configured to expose ( 110 ) a resource that is hosted at the computing device, wherein the resource comprises a digital interface for a physical entity to which the resource corresponds, and expose ( 120 ) information about a relation between a state of the resource and a state of the physical entity to which the resource corresponds. Also disclosed is a network node, the network node comprising processing circuitry that is configured to discover a resource that is hosted at the computing device, and to discover information about a relation between a state of the resource and a state of the physical entity to which the resource corresponds. The processing circuitry is further configured to prepare an action relating to the physical entity corresponding to the resource on the basis of a current state of the resource and the information, and to initiate execution of the prepared action.

First claim

The invention claimed is:

1 . A method performed by a computing device, the method comprising:
exposing a resource that is hosted at the computing device, wherein the resource comprises a digital interface for a physical entity to which the resource corresponds and wherein the resource specifies a particular view or active property of an object, and each resource is at least one of readable, writable, and executable; exposing information about a relation between a state of the resource and a state of the physical entity to which the resource corresponds, wherein the information about the relation between the state of the resource and the state of the physical entity to which the resource corresponds comprises a time required for the physical entity to undergo a change of state, and wherein the information conveys at least one of:
a delay between a change of the state of the resource and a change of the state of the physical entity to which it corresponds, and
a delay between a change of the state of the physical entity and a change in the state of the corresponding resource, and
based on the information conveying at least one of the delay between at least one of the change of the state of the resource and the change of the state of the physical entity to which it corresponds and the delay between the change of the state of the physical entity and the change in the state of the corresponding resource, modifying a start time for initiating an action to be performed by the physical entity.

2 . A computing device comprising processing circuitry that is configured to:
expose a resource that is hosted at the computing device, wherein the resource comprises a digital interface for a physical entity to which the resource corresponds and wherein the resource specifies a particular view or active property of an object, and each resource is at least one of readable, writable, and executable; expose information about a relation between a state of the resource and a state of the physical entity to which the resource corresponds, wherein the information about the relation between the state of the resource and the state of the physical entity to which the resource corresponds comprises a time required for the physical entity to undergo a change of state, and wherein the information conveys at least one of:
a delay between a change of the state of the resource and a change of the state of the physical entity to which it corresponds, and
a delay between a change of the state of the physical entity and a change in the state of the corresponding resource, and
based on the information conveying at least one of the delay between at least one of the change of the state of the resource and the change of the state of the physical entity to which it corresponds and the delay between the change of the state of the physical entity and the change in the state of the corresponding resource, modify a start time for initiating an action to be performed by the physical entity.

3 . A computing device as claimed in claim 2 , wherein the digital interface provides information about, or actuation capability on, the physical entity.

4 . A computing device as claimed in claim 2 , wherein the processing circuitry is further configured to:
receive an instruction relating to the exposed resource; and process the instruction.

5 . A computing device as claimed in claim 2 , wherein the processing circuitry is further configured to expose the information about the relation between the state of the resource and the state of the physical entity to which the resource corresponds by performing at least one of:
registering the information with a Resource Directory function; or responding to a discovery request.

6 . A computing device as claimed in claim 2 , wherein the digital interface provides information about the physical entity, and wherein the information about the relation between the state of the resource and the state of the physical entity to which the resource corresponds comprises a delay between a change in state being manifested by the physical entity and that change in state of the physical entity being reflected by a change in state of the resource.

7 . A computing device of claim 2 , wherein the digital interface provides information about actuation capability on the physical entity, and wherein the information about the relation between the state of the resource and the state of the physical entity to which the resource corresponds comprises an indication of whether execution of the actuation capability on the physical entity impacts a physical entity or system which is outside the control of the computing device.

8 . A computing device of claim 2 , wherein the digital interface provides information about actuation capability on the physical entity, and wherein the information about the relation between the state of the resource and the state of the physical entity to which the resource corresponds comprises a condition under which a state of the resource may be used to derive a value for a parameter representing a system impacted by execution of the actuation capability on the physical entity.

9 . A computing device of claim 2 , wherein the information the relation between the state of the resource and the state of the physical entity to which the resource corresponds comprises a sleep cycle specification for the computing device.

10 . A computing device of claim 2 , wherein the processing circuitry is further configured to expose the information about the relation between the state of the resource and the state of the physical entity to which the resource corresponds as at least one of:
a metadata resource; a resource attribute; and an annotation to the resource.

11 . A computing device of claim 2 , wherein the computing device is operable to run at least one of:
a Constrained Application Protocol server; and a Lightweight Machine to Machine client.
