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 |
20100268838 | METHOD AND EQUIPMENT FOR MULTI MEDIA APPLICATION MANAGEMENT USING MULTI STREAMING OF SCTP AND TIMED RELIABILITY OF PR-SCTP - Disclosed is a method for multimedia application management using a multi-streaming function of a Stream Control Transmission Protocol (SCTP) and a timed reliability function of a Partial Reliable (PR)-SCTP. The method includes calculating a number of connection objects required for transmitting at least one multimedia information, generating at least one association and stream of the SCTP to correspond to the number of the calculated connection objects, classifying the multimedia information according to purpose, granting a lifetime value to the classified multimedia information; and transmitting, via an SCTP corresponding to the lifetime value from among the SCTPs, the multimedia information to which the lifetime value is granted. | 10-21-2010 |
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 |
20120147849 | METHOD FOR SUPPORTING FLOW MOBILITY - A method of supporting flow mobility of an MN is provided in an LMA. The LMA updates a BCE when a flow of the MN moves from a first MAG to a second MAG. The LMA sends a message for requesting binding registration of the flow to the second MAG, and sends a message for requesting binding de-registration of the flow to the first MAG. | 06-14-2012 |
20120163244 | METHOD FOR SUPPORTING NODE MOBILITY IN WIRELESS MESH NETWORK - Provided is a method of data transmission from an access router in a wireless mesh network. The method of data transmission includes: receiving, from a gateway, a broadcast message indicating that a connection to the external internet can be made; establishing a bi-directional path to the gateway; | 06-28-2012 |
20130265909 | METHOD OF EXTENDING ROUTING PROTOCOL FOR M2M SERVICES IN WIRELESS MESH NETWORK - A method of extending a routing protocol for supporting an M2M service in a wireless mesh basic service set (MBSS) is provided. A method of extending a routing protocol that sets a mesh station (M-STA) that is connected to a distribution system in M-STAB of an MBSS to a mesh gate, in which the mesh gate transmits a RANN message and a gate announcement message to the M-STA, in which the mesh gate receives a path request message from the M-STA, and in which the mesh gate stores a path from the mesh gate to the M-STA based on the received path request message is provided. Because an M2M service terminal can be connected to the M-STA, the M-STA receives data from an M2M service terminal and the received data is included in a proxy update message, and the proxy update message is transmitted to the mesh gate. | 10-10-2013 |
20130322405 | METHOD FOR SUPPORTING NODE MOBILITY IN WIRELESS MESH NETWORK - Provided is a method of data transmission from an access router in a wireless mesh network. The method of data transmission includes: receiving, from a gateway, a broadcast message indicating that a connection to the external internet can be made; establishing a bi-directional path to the gateway; when a new node is connected to the access router, sending information about the new node to the gateway; if there is a data transmission in which a node located within the coverage area of the access router is a destination node, forwarding the data to the destination node. | 12-05-2013 |
20140119251 | INFORMATION SERVICE SYSTEM USING DIRECT COMMUNICATION BETWEEN VEHICLES - Disclosed herein is an information service system using direct communication between vehicles for machine-to-machine (M2M)-based intelligent transport services (ITS). The information service system includes at least one vehicle ITS station and at least one roadside device. The vehicle station and the roadside device exchange information with a server. The vehicle ITS station includes an ITS-S host configured to perform overall control, an ITS-S router configured to connect with a short or long distance communication network, to form a communication network, and to perform transmission and reception of data, and a vehicle ITS-S gateway configured to provide data received from an outside of the vehicle ITS station, that is, data provided from an electronic control unit (ECU) or a variety of types of sensors on a vehicle. The ITS-S host, the ITS-S router and the vehicle ITS-S gateway are connected over an ITS station-internal network, thereby forming a vehicle-mounted device. | 05-01-2014 |
