Abstract  Abstract

This invention claims an apparatus and a 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) and a terminal in the 3rd Generation Partnership Project (3GPP) Universal Mobile Telecommunications System (UMTS) or between a terminal in CDMA 2000 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. No system can provide remaining sessions between two terminals relating to protocol addresses between two systems and two different internets while the invention realizes the handoff processing by employing optimized transmission Multicast Internet Protocol MIP.
