Abstract

The present application describes a computer-implemented device on a network including a non-transitory memory having instructions stored thereon for registering a node with a router on the network. The device also includes a processor, operably coupled to the non-transitory memory, configured to execute the instructions of receiving, from the node over the network, a solicitation with context information including a registration start time request. The processor is also configured to execute the instructions of evaluating, at the router, whether to accept the solicitation based upon neighbor space and the received start time request. The processor is even further configured to execute the instructions of sending, to the node, an advertisement including an approved registration start time based upon the determining step.

First claim

What is claimed is:

1. A network node comprising:
a non-transitory memory having instructions stored thereon; and
a processor, operatively coupled to the memory, the processor configured to perform the instructions of:
storing context information in a context database, the context information being selected from the group consisting of supported services on an endpoint device, supported functions on the endpoint device, desired services from a router, desired functions from the router, location information of the endpoint device, location information of the router, traffic load, and combinations thereof;
receiving a message from another network node for requesting the context information and/or a local trigger for sending the context information to one or more other network nodes;
sending the context information to the one or more other network nodes; and
receiving a response from the one or more other network nodes.

2. The network node of claim 1 , wherein the network node corresponds to the router.

3. The network node of claim 1 , wherein the message, the context information and the response are communicated in a network layer.

4. The network node of claim 1 , wherein the processor is further configured to perform the instructions of transmitting a message to the endpoint device including the context information.

5. The network node of claim 4 , wherein the message is transmitted in multicast mode.

6. The network node of claim 1 , wherein the context database further stores context lifetime indicating a valid lifetime for the context information.

7. A method for a network node comprising:
storing context information in a context database, the context information being selected from the group consisting of supported services on an endpoint device, supported functions on the endpoint device, desired services from a router, desired functions from the router, location information of the endpoint device, location information of the router, traffic load, and combinations thereof;
receiving a message from another network node for requesting the context information and/or a local trigger for sending the context information to one or more other network nodes;
sending the context information to the one or more other network nodes; and
receiving a response from the one or more other network nodes.

8. The method of claim 7 , wherein the network node corresponds to the router.

9. The method of claim 8 , wherein the message, the context information and the response are communicated in a network layer.

10. The method of claim 7 , wherein the processor is further configured to perform the instructions of transmitting a message to the endpoint device including the context information.

11. The method of claim 10 , wherein the message is transmitted in multicast mode.

12. The method of claim 7 , wherein the context database further stores context lifetime indicating a valid lifetime for the context information.
