Abstract

The present invention provides a method involving at least one mobile node and a heterogeneous network comprising a plurality of access nodes. One embodiment of the method includes providing at least one first message including information indicative of a selected access node. The access node is selected to provide command services to the at least one mobile node.

Claims

1. A method, comprising:

providing, from a mobile node to a node in an access network prior to a subsequent handover of the mobile node, a request to have the node provide media independent handover (MIH) command services to the mobile node to control reconfiguration or selection of an appropriate link for the subsequent handover through a set of handover commands, wherein the MIH command services enable a mobility management layer or one or more higher layers to control at least one of physical, data link, and logical link layers during the subsequent handover of the mobile node.

2. The method of claim 1, wherein providing the request comprises providing a request generated at a MIH layer implemented between a mobility management layer and the physical, data link, and logical link layers in the mobile node.

3. The method of claim 2, wherein providing the request comprises providing information indicative of at least one threshold for reporting at least one event associated with a heterogeneous network.

4. The method of claim 1, wherein providing the request comprises providing at least one handover policy that has been provisioned to the mobile node by a service provider, and comprising forming a media independent pairing between the mobile node and the node in the access network in response to providing the request.

5. The method of claim 1, wherein the node is a point of attachment or point of service for the mobile node in the access network.

6. The method of claim 5, comprising selecting, at the mobile node, the node in the access network based on at least one policy associated with the mobile node.

7. The method of claim 6, wherein providing the request comprises providing information indicative of said at least one policy generated by a policy engine.

8. The method of claim 1, comprising receiving, at the mobile node from the node in the access network, at least one response to the request, said at least one response indicating that the node in the access network confirms registration of the mobile node.

9. The method of claim 8, wherein receiving the response comprises receiving, at the mobile node, a request to report at least one event associated with the mobile node to the node in the access network.

10. The method of claim 9, comprising providing, from the mobile node to the node in the access network, at least one further response including information indicative of at least one event associated with the mobile node.

11. A method, comprising:

receiving, from a mobile node at a node in an access network prior to a subsequent handover of the mobile node, a request for the node to provide media independent handover (MIH) command services to the mobile node, wherein the MIH command services enable a mobility management layer or one or more higher layers to control at least one of physical, data link, and logical link layers during the subsequent handover of the mobile node, and wherein receiving the request comprises receiving information indicating that the mobile node has selected the node in the access network to provide the MIH command services to control reconfiguration or selection of an appropriate link for the subsequent handover through a set of handover commands.

12. The method of claim 11, wherein receiving the request comprises receiving the request at a MIH layer in the node in the access network, wherein the request is generated at a MIH layer implemented in the mobile node, and further comprising forming a media independent pairing between the mobile node and the node in the access network in response to receiving the request.

13. The method of claim 11, wherein the node is a point of attachment or a point of service for the mobile node in the access networks.

14. The method of claim 13, wherein receiving the request comprises receiving information indicative of at least one policy generated by a policy engine that can be used to select the node in the access network.

15. The method of claim 12, wherein receiving the request comprises receiving information requesting reporting at least one event associated with a heterogeneous network to the mobile node.

16. The method of claim 15, wherein receiving the request comprises receiving information indicative of at least one threshold for reporting said at least one event associated with the heterogeneous network.

17. The method of claim 11, comprising providing, from the node in the access network to the mobile node, a response to receiving at least one first message indicating that the node in the access network confirms registration of the mobile node.

18. The method of claim 17, wherein providing the response comprises providing a request to report at least one event associated with the mobile node.

19. The method of claim 18, wherein providing the response comprises providing, to the mobile node, information indicative of at least one threshold for reporting said at least one event associated with the mobile node.

20. The method of claim 18, comprising receiving, at the node in the access network from the mobile node, information indicative of at least one event associated with the mobile node.

21. A method, comprising:

providing, from a mobile node to a node in an access network, a request to have the node provide media independent handover (MIH) command services to the mobile node, wherein the MIH command services enable a mobility management layer or one or more higher layers to control at least of one of physical, data link, and logical link layers, and wherein the MIH command services enable the mobility management layer or the one or more higher layers to control reconfiguration or selection of an appropriate link for a handover of the mobile node through a set of handover commands.
