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.
Claims11
A method for handing off a communication session from a first terminal having a first internet protocol (IP) address to a second terminal having a second IP address, the method comprising:
- requesting a handoff of a current communication session from the first terminal to the second terminal wherein the request for handoff is based on a link performance metric;
- obtaining connection information associated with the second terminal, the connection information including the second IP address of associated with the second terminal;
- receiving a confirmation of the second IP address;
- and
- rerouting the current communication session from the first terminal to the second terminal based on the second IP address.
