| 20100061270 | NETWORK MOVEMENT DETECTION METHOD IN MOBILE NODE OF DSMIP6 ENVIRONMENT - 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. | 03-11-2010 |
| 20100157894 | METHOD OF OPERATING TUNNEL POINT SUPPORTING ROUTING SCALABILITY AND MOBILITY - Provided is a method of operating a tunnel point that provides a tunnel between a router group including at least one router and a mobile node. The method includes: providing a tunnel between the mobile node and the router group by authenticating the mobile node; receiving a packet including an identifier (ID) of a target node from the mobile node; converting the ID of the target node in the packet into a locator corresponding to the ID of the target node; transmitting a packet including the converted locator to the router group; and maintaining the ID of the mobile node by authenticating the mobile node through the router group when the mobile node is connected to another external terminal node. | 06-24-2010 |
| 20100172298 | APPARATUS AND METHOD FOR SUPPORTING MOBILITY OF SENSOR NODE IN IP-BASED SENSOR NETWORKS - A method and apparatus for managing mobility of a sensor node in an Internet Protocol (IP)-based sensor network including a plurality of personal area networks (PANs) is provided. The apparatus for managing mobility of a sensor node in a personal area network (PAN), the apparatus including: a sensor node sensing unit to sense a sensor node moving into the PAN from another PAN; a proxy binding update (PBU) message generation unit to generate location change information of the sensed sensor node; and a PBU message transmission unit to transmit the location change information. | 07-08-2010 |
| 20100174828 | METHOD AND SYSTEM FOR OPTIMIZING ROUTING BETWEEN NODES IN PROXY MOBILE IPv6 NETWORK - A method and system for | 07-08-2010 |
| 20100189037 | METHOD AND SYSTEM FOR MANAGING MOBILE ROUTER IN PROXY MOBILE INTERNET PROTOCOL VERSION 6 DOMAIN - A system for managing mobile routers connected to a PMIP6 (proxy mobile interne protocol version 6) domain is provided with a plurality of MAGs (mobility access gateways) to which the mobile routers are to be connected, an LMA (local mobility anchor), connected to the plurality of MAGs, for managing location information of the mobile routers and packet forwarding information of the mobile routers, and a profile server in which profile information of the mobile routers is registered. Further, the plurality of MAGs and the LMA set up forwarding information of a home prefix of a mobile router that is connected to the PMIP6 domain and a mobile network prefix managed by the connected mobile router, based on the profile information of the mobile routers registered in the profile server. | 07-29-2010 |
| 20100316005 | AUTOMATIC TUNNEL CONFIGURATION METHOD USING ROUTER ADVERTISEMENT MESSAGE - An automatic tunnel configuration method using a router advertisement message is provided, including: periodically receiving a router advertisement message containing a tunnel end-point address option from an access router of an internet protocol version 6 (IPv6) network when a mobile node moves from a home network to other IPv6 networks; automatically configuring a tunnel using an address allocated from the access router of the IPv6 network to which the mobile node connects, and the tunnel end-point address option included in the router advertisement message when the network to which the mobile node moves to connect is an internet protocol version 4 (IPv4) network; and communicating with a correspondent node via the configured tunnel using a mobile internet protocol (MIP6). | 12-16-2010 |
| 20110002300 | METHOD OF PERFORMING HANDOVER AND NETWORK SYSTEM OF ENABLING THE METHOD - A method of performing a handover is provided. The method of performing the handover includes: a mobile terminal transmitting an access stop message to a first Access Point (AP) when the mobile terminal moves from a first AP area to a second AP area; the first AP transmitting a handover start message to a first Mobility Access Gateway (MAG) corresponding to the first AP in response to the access stop message; the first MAG transmitting the handover start message to a Local Mobile Anchor (LMA); and the LMA performing a buffering of a data packet to be transmitted to the mobile terminal. | 01-06-2011 |
| 20110096782 | METHOD FOR CONVERTING NETWORK ADDRESS - In a network environment in which an endpoint identifier and a routing locator are separated from each other, a first router receives a data packet including an endpoint identifier of a first host and an endpoint identifier of a second host that is a communication target of the first host from the first host managed by the first router in order to convert a network address. A message requesting external address prefix information of the second host is transmitted to a second router managing the second host. In addition, the external address prefix information is received from the second router and a routing locator of the second host is generated by converting internal address prefix information of an endpoint identifier of the second host into the external address prefix information of the second host in the data packet. | 04-28-2011 |
| 20110134854 | MULTI-CHANNEL AND MULTI-INTERFACE MESH ROUTER AND METHOD FOR ASSIGNING CHANNEL ACCORDING TO FIXED DISTRIBUTION SCHEME - Provided is multi-channel and multi-interface mesh router and method of assigning a channel according to a fixed distribution scheme. The channel assignment method may configure a neighbor information table, a parent list, and a dependent list through exchanging of information between mesh routers, and may determine a channel assignment order based on the parent list and the dependent list and then assign a channel, beginning with a mesh router selected as a seed node, and sequentially transmit channel assignment information to mesh routers included in the dependent list. | 06-09-2011 |
