1. A method comprising:
- registering a first device with a home agent, wherein registering the first device associates a care of address (CoA) for the first device with a home address (HoA), and a first binding identification (BID) in a binding table of the home agent;
the first device sending a first binding update to the home agent to establish a flow, the first binding update comprising a first traffic selector and a first action, wherein the first action indicates that messages matching the first traffic selector is to be forwarded to an address that is identified by the first HoA and the first BID in the binding table of the home agent; and
the first device sending a second binding update to the home agent to transfer the flow to a second device, the second binding update comprising a second traffic selector and a second action, wherein the second action indicates that a second message of a plurality of messages is to be forwarded to an address that is identified by a second HoA and a second BID in the binding table at the home agent.

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.

9. A method comprising:
-
a home agent (HA) receiving registration information for a first device from the first device; associating a first care of address (CoA) for the first device with a first home address, HoA, and a first a binding identification (BID) in a binding table of the HA, wherein the first CoA is uniquely identifiable in the binding table based on the first HoA and the first BID; the home agent receiving a first binding update from the first device, the first binding establishing a flow, the first binding update comprising a first traffic selector and a first action, wherein the first action indicates that messages matching the first traffic selector to be forwarded to an address that is identified by the first HoA and the first BID in the binding table of the HA; the home agent routing the messages matching the first traffic selector to the first device at the first CoA; the home agent receiving a second binding update from the first device to transfer the flow to a second device, the second binding update comprising a second traffic selector and a second action, wherein the second action indicates that messages matching the second traffic selector and a second BID in the binding table at the home agent be forwarded to an address that is identified by a second HoA; and the home agent routing the messages matching the second traffic selector to the second device at a second CoA. - View Dependent Claims (10, 11, 12, 13, 14)

15. A Wireless Transmit/Receive Unit (WTRU) comprising:
a processor configured to; register the WTRU with a home agent (HA), wherein registering the WTRU associates a care of address, CoA, for the WTRU with a first home address, HoA, and a first a binding identification, BID, in a binding table of the HA; send a first binding update to the home agent to establish a flow, the first binding update comprising a first traffic selector and a first action, wherein the first action indicating that a packet is to be forwarded from the home agent to an address that is identified by the first HoA and the first BID in the binding table of the home agent; and send a second binding update to the home agent to transfer the flow to a second WTRU, the second binding update comprising a second traffic selector and a second action, wherein the second action indicates that the packet is to be forwarded to an address that is identified by a second HoA and a second BID in the binding table at the home agent. - View Dependent Claims (16, 17, 18, 19)
