Abstract

The present invention provides a method involving at least one mobile node and a heterogeneous network comprising a plurality of access nodes. The method includes transferring event context information associated with a mobile node from a first access node to a second access node.

Claims

1. A method involving at least one mobile node and a heterogeneous network comprising a plurality of access nodes, comprising:

transferring event context information associated with a mobile node from a first access node to a second access node.

2. The method of claim 1, wherein transferring the event context information to the second access node comprises transferring the event context information to the second access node in response to determining that the mobile node is associated with the second access node.

3. The method of claim 2, comprising determining that the mobile node is associated with or pending association with the second access node.

4. The method of claim 3, wherein determining that the mobile node is associated with or pending association with the second access node comprises accessing information indicative of a handoff of the mobile node from the first to the second access node.

5. The method of claim 3, wherein determining that the mobile node is associated with the second access node comprises determining that the mobile node is associated with the second access node based on a registration request message provided to the second access node by the mobile node.

6. The method of claim 5, comprising receiving the registration request message.

7. The method of claim 6, wherein receiving the registration request message comprises receiving a registration request message indicating that the second access node is the controlling access node for the mobile node.

8. The method of claim 1, wherein transferring the event context information comprises transferring the event context information from a media independent handover layer in the first access node to a media independent handover layer in the second access node.

9. The method of claim 1, wherein transferring the event context information comprises transferring event context information associated with the mobile node and the first access node.

10. The method of claim 1, comprising forming at least one event report based on the transferred event context information.

11. The method of claim 1, comprising forming at least one event session identifier based on the transferred event context information.

12. The method of claim 1, comprising transmitting a deregistration message from the first access node to the mobile node indicating that the second access node will receive event reports.

13. The method of claim 1, comprising registering events indicated by the event context information with a media independent handoff function or layer in the mobile node.
