Method and system for user initiated inter-device, inter-system, and inter-internet protocol address handoff
First Claim
1. A method for providing a handoff (HO) between first and second wireless terminals respectively configured for communication with first and second systems, said first terminal being different from said second terminal, said first system having a technology standard different from said second system, and respectively identified by different internet protocol (IP) addresses, comprising:
- a) said first terminal initiating a request for an HO to said second terminal during a current session with said first system;
b) alerting the first terminal to ensure that the second terminal is on and is connected to the second system;
c) inquiring if the first system has the connection information;
d) obtaining the IP address of the second terminal from said connection information; and
e) initiating a rerouting process of said current session from said first terminal to said second terminal responsive to receipt of a confirmation of the second terminal IP address.

Abstract
Apparatus and method by which Internet Protocol (IP) traffic can be transferred (i.e. handoff) between two different terminals operating according to two different technology standards in two different systems with two different IP addresses. For example, a session handoff can be made between a terminal in Wireless Local Area Network (WLAN) a terminal in a 3GPP UMTS or between a terminal in CDMA2000 and a terminal in a 3GPP UMTS. These terminals can be either physically separate entities or logical entities that are encapsulated within a common enclosure.
