Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a system which can transfer existing sessions between two terminals that use two different IP addresses between two systems.

SOLUTION: An apparatus and a method can transfer (handoff) Internet Protocol (IP) traffic between two different terminals which operate according to two different technology standards using two different IP addresses between two different systems. For example there is session handoff between a wireless local area network (WLAN) terminal and a 3GPP UMTS terminal or between a CDMA2000 terminal and the 3GPP UMTS terminal. The terminals may be a physically individual entity or an independent logical entity which is stored in a common housing.
