PROBLEM TO BE SOLVED: To solve the problem in which, in a 3GPP system that supports IMS, an inter-UE transfer is performed by a WTRU that supports an IMS-session initiation protocol and an IUT allows a communication session to be transferred from one WTRU to another WTRU but there is no standardized solution for non-IMS terminals (packet switched streaming service capable terminals, real time streaming protocol/real time control protocol terminals, and/or HTTP).SOLUTION: A WTRU receives a first data flow from a source device such as a correspondence node and performs a seamless IUT such that the correspondence node is unaware that the flow has been transferred to a different WTRU. The WTRU registers with a first home agent, which receives a plurality of messages addressed to a home address. The home agent forwards the messages to the WTRU at a first care-of address. |
