Summary:A technology is disclosed for preventing packet and transferring packets to a switched interface with minimal delay, when a mobile node switches a using interface. According to the technology, when a MN 200 is communicating with a MAG (WLAN) 232, a PBU message 301 has already been transmitted from the MAG (WLAN) 232 to the LMA 220, and binding related to a WLAN connection 242 is already registered in the LMA 220. When an interface switching event 300 is generated, the MN 200 transmits to the MAG (WLAN) 232 via the WLAN connection 242, a binding in-advance registration message 302 for registering a binding in advance. When the MAG (WLAN) 232 detects disconnection 310 of the WLAN connection 242, the MAG (WLAN) 232 transmits a registration delete/trigger message 312a to the LMA 220, registers and triggers in the LMA 220 the in-advance registration binding registered in the MAG (WLAN) 232, and deletes the PBU message 301.
