INTERFACE SWITCHING SYSTEM, MOBILE NODE, PROXY NODE, AND MOBILE MANAGEMENT NODE

Title:

INTERFACE SWITCHING SYSTEM, MOBILE NODE, PROXY NODE, AND MOBILE MANAGEMENT NODE

Document Type and Number:

WIPO Patent Application WO/2010/041440

Kind Code:

A1

Abstract:

Disclosed is a technique for preventing a packet loss and transferring a packet to the switched interface with the smallest delay when a mobile node performs switching of an interface to be used from one to another. According to the technique, when MN (200) is communicating with a MAG (WLAN) (232), a PBU message (301) has been transmitted from MAG (WLAN) (232) to LMA (220) and binding relating to a WLAN connection (242) is already registered in the LMS (220). When an interface switching event (300) is generated, the MN (200) transmits a binding in-advance registration message (302) for performing in-advance registration of the binding to the MAG (WLAN) (232) via the WLAN connection (242). Upon detection of a disconnection (310) of the WLAN connection (242), the MAG (WLAN) (232) transmits a registration delete/trigger message (312a) to the LMA (220) so as to register in the LMA (220) for trigger, the in-advance registration binding registered in the MAG (WLAN) (232) and deletes the binding of the PBU message (301).
