Event context transfer in a heterogeneous communication system
First Claim
Patent Images
1. A method, comprising:
- receiving, at a first access node, a message indicating that a mobile node has selected a second access node as a controlling access node for media independent handover (MIH) commands so that media independent handover (MIH) commands, upon being invoked in a layer stack of the second access node, propagate to a layer stack of the mobile node; and
transferring event context information associated with the mobile node from the first access node to the second access node dependent on the first access node receiving the message, the event context information indicating an event context state of the mobile node and at least one trigger for reporting at least one event between the mobile node and the second access node following handoff of the mobile node to the second access node, the at least one event indicating a change in state or a transmission behavior of at least one of a physical layer, a data link layer, or a logical link layer used for communication between the mobile node and the second access node following handoff of the mobile node to the second access node.

7. A method, comprising:
-
transmitting, from a first access node, a message indicating that a mobile node has selected the first access node as a controlling access node for media independent handover (MIH) commands; receiving, at the first access node, event context information associated with the mobile node from a second access node dependent on transmission of the message, the event context information indicating an event context state of the mobile node and at least one trigger for reporting at least one event between the mobile node and the first access node following handoff of the mobile node to the first access node, the at least one event indicating a change in state or a transmission behavior of at least one of a physical layer, a data link layer, or a logical link layer used for communication between the mobile node and the first access node following handoff of the mobile node to the first access node; invoking at least one MIH command in a layer stack of the first access node, and propagating the at least one MIH command to a layer stack of the mobile node. - View Dependent Claims (8, 9, 10, 11)

12. An apparatus, comprising:
a first access node configured to; receive a message indicating that a mobile node has selected a second access node as a controlling access node for media independent handover (MIH) commands so that media independent handover (MIH) commands, upon being invoked in a layer stack of the second access node, propagate to a layer stack of the mobile node; and transfer event context information associated with the mobile node from the first access node to the second access node dependent on the first access node receiving the message, the event context information indicating an event context state of the mobile node and at least one trigger for reporting at least one event between the mobile node and the second access node following handoff of the mobile node to the second access node, the at least one event indicating a change in state or a transmission behavior of at least one of a physical layer, a data link layer, or a logical link layer used for communication between the mobile node and the second access node following handoff of the mobile node to the second access node. - View Dependent Claims (13, 14, 15, 16, 17)

18. An apparatus, comprising:
a first access node configured to; transmit a message indicating that a mobile node has selected the first access node as a controlling access node for media independent handover (MIH) commands; invoke at least one MIH command in a layer stack of the first access node; propagate the at least one MIH command to a layer stack of the mobile node; and receive event context information associated with the mobile node from a second access node dependent on transmission of the message, the event context information indicating an event context state of the mobile node and at least one trigger for reporting at least one event between the mobile node and the first access node following handoff of the mobile node to the first access node, the at least one event indicating a change in state or a transmission behavior of at least one of a physical layer, a data link layer, or a logical link layer used for communication between the mobile node and the first access node following handoff of the mobile node to the first access node. - View Dependent Claims (19, 20, 21, 22)

23. A system, comprising:
-
a first access node; and a second access node, wherein event context information associated with the mobile node is transferred from the first access node to the second access node dependent on the first access node receiving a message indicating that a mobile node has selected the second access node as a controlling access node for media independent handover (MIH) commands, the event context information indicating an event context state of the mobile node and at least one trigger for reporting at least one event between the mobile node and the second access node following handoff of the mobile node to the second access node, the at least one event indicating a change in state or a transmission behavior of at least one of a physical layer, a data link layer, or a logical link layer used for communication between the mobile node and the second access node following handoff of the mobile node to the second access node, and wherein the second access node is configured to invoke at least one MIH command in a layer stack of the second access node and propagate the at least one MIH command to a layer stack of the mobile node. - View Dependent Claims (24, 25, 26, 27, 28, 29)
