Abstract
In order to verify if upper-level router information, or ULRI (information on the upper-level router with respect to a predetermined node) is valid, MN (Mobile Node) 220 associated to ULMR (Upper-Level Mobile Router) 210 acquires ULRI such as the address of ULMR (310), inserts ULRI into a BU (Binding Update) message, and sends it to HA (Home Agent) 235 (320). On receiving the BU message with ULRI, HA sends a BA (Binding Acknowledgement) message set to pass through the router that is specified in ULRI (330). If ULRI is valid, ULMR forwards the BA message to MN (340). If ULRI is not valid, ULMR discards the BA message.
