Inter-unit transfer support using mobile internet protocol
First Claim
1. A method of transferring a flow from a first wireless transmit/receive unit (WTRU), the method comprising:
- establishing the flow with a node, wherein the flow is established by sending a first binding update, wherein the first binding update comprises a first traffic selector;
sending an inter-unit transfer (IUT) preparation request from the first WTRU to a second WTRU;
receiving, from the second WTRU, an IUT preparation response indicating the second WTRU accepts the IUT; and
sending, based on the received IUT preparation response, a second binding update to a HA, wherein the second binding update comprises a second traffic selector to route packets belonging to the flow to the second WTRU.

Abstract
A WTRU may receive a first data flow from a source device such as a correspondence node and perform a seamless IUT such that the correspondent node is unaware that the flow has been transferred to a different WTRU. The WTRU may register with a first home agent, wherein the first home agent receives a plurality of messages addressed for a home address. The home agent may forward the messages to the WTRU at a first care-of-address. The WTRU may send a binding update to the first home agent. The binding update may comprise a second traffic selector and a second action. The second action may specify that a second message of the plurality of messages is to be forwarded to a different WTRU when the second message matches the second traffic selector.

1. A method of transferring a flow from a first wireless transmit/receive unit (WTRU), the method comprising:
-
establishing the flow with a node, wherein the flow is established by sending a first binding update, wherein the first binding update comprises a first traffic selector; sending an inter-unit transfer (IUT) preparation request from the first WTRU to a second WTRU; receiving, from the second WTRU, an IUT preparation response indicating the second WTRU accepts the IUT; and sending, based on the received IUT preparation response, a second binding update to a HA, wherein the second binding update comprises a second traffic selector to route packets belonging to the flow to the second WTRU. - View Dependent Claims (2, 3)

4. A method of transferring a flow to a second wireless transmit/receive unit (WTRU), the method comprising:
-
receiving an inter-unit transfer (IUT) preparation request from a first WTRU; performing an application IUT preparation; sending an IUT preparation response indicating that the second WTRU accepts the IUT or is ready for the IUT; and sending a binding update to a HA, wherein the binding update comprises a traffic selector to route packets belonging to the flow to the second WTRU. - View Dependent Claims (5, 6, 7)
