Abstract

In one embodiment, a method for monitoring events in a home network is provided. A node receives a subscription request from a control point, wherein the subscription request indicates an interest in delayable eventing. A change is detected in an event variable. It is then determined if the control point can receive an event sent from the node. If the control point cannot receive an event sent from the node, an event notification regarding the change in the event variable is stored such that the event notification can be retrieved when the control point can receive communications from the node.

Claims

1. A method for monitoring events in a home network, the method comprising:

receiving, at a node, a subscription request from a control point, wherein the subscription request indicates an interest in delayable eventing;

detecting a change in an event variable;

determining if the control point can receive an event sent by the node;

if the control point cannot receive the event sent by the node, storing an event notification regarding the change in the event variable such that the event notification can be retrieved when the control point can receive communications from the node.

2. The method of claim 1, further comprising:

determining if the control point should receive an event notification regarding the change in the event variable;

3. The method of claim 1, wherein the node is a home network device.

4. The method of claim 1, wherein the node is a proxy between the control point and a home network device.

5. The method of claim 1, wherein the subscription request further contains a duration for delayable eventing and the storing only occurs if the duration has not been exceeded.

6. The method of claim 5, further comprising:

receiving a renewing subscription request form the control point after the duration has expired, wherein the renewing subscription request contains a second duration, wherein the storing occurs if the second duration has not been exceeded.

7. The method of claim 1, wherein a control point cannot receive communications from the node if the control point has been disconnected from the home network.

8. The method of claim 1, wherein a control point cannot receive communications from the node if the control point has entered a “

sleep”

mode.

9. The method of claim 1, wherein the control point cannot receive communications from the node if the node has been disconnected from the home network.

10. The method of claim 7, wherein, upon reconnection of the control point to the home network, the node receives a renewal message from the control point, and wherein the node, in response to the renewal message, sends the event notification regarding the change in the event variable.

11. The method of claim 7, wherein, upon awakening of the control point from “

sleep”

mode, the node receives a renewal message from the control point, and wherein the node, in response to the renewal message, sends the event notification regarding the change in the event variable.

12. The method of claim 7, wherein, upon reconnection of the node to the home network, the node sends the event notification regarding the change in the event variable.

13. A system for monitoring events in a home network, the system comprising:

one or more control points;

a node configured to;

receive, at a node, a subscription request from a control point, wherein the subscription request indicates an interest in delayable eventing;

detect a change in an event variable;

determine if the control point can receive an event sent by the node; and

if the control point cannot receive the event sent by the node, store an event notification regarding the change in the event variable such that the event notification can be retrieved when the control point can receive communications from the node.

14. The system of claim 13, wherein the node is a home network device.

15. The system of claim 13, wherein the node is a proxy between the control point and a home network device.

16. An apparatus for monitoring events in a home network, the apparatus comprising:

means for receiving, at a node, a subscription request from a control point, wherein the subscription request indicates an interest in delayable eventing;

means for detecting a change in an event variable;

means for determining if the control point can receive an event sent by the node; and

means for, if the control point cannot receive the event sent by the node, storing an event notification regarding the change in the event variable such that the event notification can be retrieved when the control point can receive communications from the node.

17. A program storage device readable by a machine tangibly embodying a program of instructions executable by the machine to perform a method for monitoring events in a home network, the method comprising:

receiving, at a node, a subscription request from a control point, wherein the subscription request indicates an interest in delayable eventing;

detecting a change in an event variable;

determining if the control point can receive an event sent by the node; and

if the control point cannot receive the event sent by the node, storing an event notification regarding the change in the event variable such that the event notification can be retrieved when the control point can receive communications from the node.
