description PROBLEM TO BE SOLVED: To provide a mobile control network system capable of reducing packet loss when a mobile node frequently moves between small areas, and to provide a router and a mobile terminal. SOLUTION: In a mobile control network 90, a one-to-many path (P2MP LSP41) is established from an Ingress LSR 21 to Egress LSRs 11 through 13. The Egress LSR 11 establishing a radio link 91 between itself and MN1 transfers packets to the MN and the Egress LSRs 12, 13 buffer the packets. When radio link is established with the Egress LSR 13 along with the movement of the MN, the packet buffered in the Egress LSR 13 is received to avoid packet loss in the MN. A packet transfer path is changed from the P2MP LSP 41 to P2MP LSP42 in preparation for the subsequent movement of the MN. COPYRIGHT: (C)2008,JPO&INPIT
