Abstract
A technology is disclosed in which, when a normal mobile node (that does not newly provide a dedicated function) is used, signaling for reconfiguring a tunnel during a mobile node movement is reduced and, furthermore, packet loss is reduced. In the technology, when an MN moves from under the control of an ARthat is a movement origin to be under the control of an ARthat is a movement destination, the ARreceives an NS transmitted from the MN to the AR. The ARthat receives the NS destined to the ARtransmits a 'Location Update' to the AR. The ARthat receives the 'Location Update' uses an MN management table of the relevant MN and creates “Prefix Information” and returns the “Prefix Information” to the AR. A tunnel is established between access routers of the ARand ARthrough use of the “Prefix Information”, and a packet destined to the MN is transferred to the MN via the tunnel.
