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 on the home network, a subscription request from a control point on the home network, wherein the subscription request contains a variable that explicitly indicates whether or not the control point has an interest in delayable eventing;

when an event variable changes, determining if the control point had indicated an interest in delayable eventing for the event variable in a subscription request sent from the control point, wherein the event variable changing indicates the addition or deletion of a file, and if so;

determining if the control point can receive an event notification 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; and

sending the stored event notification regarding the change in the event variable to the control point when the control point can receive the notification.

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

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

sleep”

mode.

10. 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.

11. The method of claim 1, wherein the subscription request indicates whether or not the control point has an interest in delayable eventing though the use of a dedicated field in a header of a subscription request to indicate delayable eventing interest.

12. 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 contains a variable that explicitly indicates whether or not the control point has an interest in delayable eventing;

when an event variable changes, determining if the control point had indicated an interest in delayable eventing for the event variable in a subscription request sent from the control point, and if so;

determining if the control point can receive an event notification 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; and

sending the stored event notification regarding the change in the event variable to the control point when the control point can receive the notification;

wherein a control point cannot receive communications from the node if the control point has been disconnected from the home network and 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.

13. 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 contains a variable that explicitly indicates whether or not the control point has an interest in delayable eventing;

when an event variable changes, determining if the control point had indicated an interest in delayable eventing for the event variable in a subscription request sent from the control point, and if so;

determining if the control point can receive an event notification 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; and

sending the stored event notification regarding the change in the event variable to the control point when the control point can receive the notification;

wherein a control point cannot receive communications from the node if the control point has been disconnected from the home network and 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.

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

one or more control points on the home network;

a hardware node device on the home network configured to;

receive, at the node device, a subscription request from a control point, wherein the subscription request contains a variable that explicitly indicates whether or not the control point has an interest in delayable eventing;

when an event variable changes, determine if the control point had indicated an interest in delayable eventing for the event variable in a subscription request sent from the control point, wherein the event variable changing indicates the addition or deletion of a file, and if so;

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

if the control point cannot receive the event sent by the node device, 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; and

send the stored event notification regarding the change in the event variable to the control point when the control point can receive the notification.

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

16. The system of claim 14, wherein the node device is a proxy between the control point and a home network device.

17. A non-transitory 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 on the home network, a subscription request from a control point on the home network, wherein the subscription request contains a variable that explicitly indicates whether or not the control point has an interest in delayable eventing;

when an event variable changes, determining if the control point had indicated an interest in delayable eventing for the event variable in a subscription request sent from the control point, wherein the event variable changing indicates the addition or deletion of a file, and if so;

determining if the control point can receive an event notification 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; and

sending the stored event notification regarding the change in the event variable to the control point when the control point can receive the notification.
