摘要： Provided is a method of performing a handover in a mobile communication environment. The method of performing the handover using a mobile node (MN) that moves from a first access router (AR) network to a second AR network in a mobile Internet protocol (IP) network includes: (a) the MN providing a new care of address (CoA) allocation method to the second AR, the second AR previously obtaining a CoA according to the CoA allocation method; (b) after the MN completely performing the handover to a subnet of the second AR in a layer 2 of the MN, clearly informing the first AR that the MN moves; and (c) allocating a new CoA (NCoA) obtained by the second AR to the MN, the first AR starting to tunnel packets destined for a previous CoA (PCoA) to the NCoA, and normally performing a binding update process for a mobile IP. The method replaces a conventional fast handover method, and simplifies complicated message exchanges.

摘要： There is provided a movement detection method of a mobile node in a DSMIP6 environment. The movement detection method includes performing neighbor unreachability detection in a network to which a mobile node moves, confirming network movement detection and simultaneously performing IPv4 address allocation when the neighbor unreachability detection fails, performing router discovery at the same time as the IPv4 address allocation, recognizing the movement detection into the IPv4 network when the IPv4 address allocation succeeds, and recognizing the movement detection into the IPv6 network when the router discovery and the IPv6 router discovery succeed. Therefore, the movement detection method can be useful to continuously perform operations as defined in a DSMIP6 specification so as to confirm whether the network to which the mobile node moves is an IPv6 network or an IPv4 network and detect movement to the confirmed network, and to perform a binding update in time.

摘要： A method of transmitting a neighbor discovery protocol (NDP) message in an IEEE 802.16/Wibro network is provided. The method of transmitting an NDP message in a sub-network formed with access routers and a plurality of base stations connected to the access router through separate interfaces includes: a first base station transmitting a first NDP message received from a first terminal, to the access router; and the access router transmitting the first NDP message to the remaining base stations excluding the first base station. According to the method, a method of processing an NDP message in an environment having multiple base stations which cannot be considered under a conventional environment using a multicast connection ID (CID) can be improved, and problems that can occur when a IPv6 is introduced in an IEEE 802.16/Wibro network can be solved.
