ABSTRACT:
A technique is disclosed, by which a mobile terminal (mobile node) performing handover can quickly and continuously receive after the handover the additional services as it has been receiving before the handover. According to this technique, MN (mobile node; mobile terminal)10transmits a message including a session identifier or the like of a path24to QNE (proxy)68under the condition connected to AR (access router)21before the handover. QNE62and QNE63on a path34where this message is transferred are present on the path24, and its own interface address is added to the message. On the other hand, QNE67is not present on the path24and transfers the message as it is. As a result, QNE (proxy)68determines QNE63as a crossover node and turns the path upstream from QNE63to an identical path, while a path35as changed from a downstream path can be set as a path to be used by MN after the handover.
