Network layer end-point transfer
First Claim
1. A method for handing off an end-point associated with a first device to a second device, the first and second devices being within a locally accessible network, the locally accessible network operating in an Internet protocol (IP) environment, the IP environment of each device being configured to store multiple IP addresses, the first device being in a currently established session with a third device within the IP environment via a router, the method comprising:
- locally transferring end-point information including an IP address associated with the end-point of the first device to the second device within the locally accessible network;
configuring a further end-point by the second device using the transferred end-point information, the further end-point being compatible with the currently established session; and
broadcasting, by the second device, an announcement to the locally accessible network, including the router, that the second device is associated with the further end-point, whereby the router receives the announcement and redirects IP packets from the third device previously associated with the end-point associated with the first device to the further end-point associated with second device.

Abstract
Methods and apparatus for handing off an end-point associated with a first device to a second device within a locally accessible network operating in an Internet protocol (IP) environment that supports multiple addresses for each device are provided. The first device is in a currently established session with a third device within the IP environment. End-point information associated with the end-point of the first device is locally transferred to the second device. A further end-point, compatible with the currently established session, is configured by the second device using the transferred end-point information. The second device broadcasts an announcement to the locally accessible network, including the router, that the second device is associated with the further end-point.

9. A method for handing-off an end-point associated with a first device to a second device, the first and second devices being within a locally accessible network, the locally accessible network operating in an Internet protocol (IP) environment, the IP environment supporting multiple IP addresses for each device, the first device being in a currently established session with a third device within the IP environment via a router, the method comprising:
-
transmitting an initialization message from the first device to the second device to condition the second device to receive end-point information associated with the end-point;
transmitting an end-point message from the first device to the second device, the end-point message including the end-point information associated with the first device, the end-point information includes an IP address;
configuring a further end-point by the second device using the transferred end-point information, the further end-point being compatible with the currently established session; and
broadcasting an advertisement message to the locally accessible network including to the router to announce hand-off of the end-point, whereby IP packets from the third device to the first device are redirected by the router to the second device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. Apparatus for handing off an end-point associated with a first device to a second device, the first and second devices being within a locally accessible network, the locally accessible network operating in an Internet protocol (IP) environment, the IP environment supporting multiple IP addresses for each device, the first device being in a currently established session with a third device within the IP environment via a router, the apparatus comprising:
-
means for locally transferring end-point information including an IP address associated with the end-point of the first device to the second device within the locally accessible network;
means for configuring a further end-point by the second device using the transferred end-point information, the further end-point being compatible with the currently established session; and
means for broadcasting, by the second device, an announcement to the locally accessible network, including the router, that the second device is associated with the further end-point, whereby the router receives the announcement and redirects IP packets from the third device previously associated with the end-point associated with the first device to the further end-point associated with second device. - View Dependent Claims (21, 22, 23, 24, 25, 26)
