Abstract:
An apparatus and method for supporting mobility of a mobile terminal in a wireless local area network (LAN) environment deploying mobile IP are provided. The method for registering a mobile node using a virtual mobile node comprises: detecting whether or not a mobile node traveling among a plurality of networks is connected; and registering information on the mobile node whose connection is detected, with an agent relaying communication between the mobile node and a correspondent agent. By doing so, even when a mobile IP module is not installed, the mobile node can perform wireless communication seamlessly between networks in a wireless LAN environment deploying mobile IP.
Abstract:
Provided is a content recommending method including receiving from second users meta data regarding content belonging to each of the second users having a content preference similar to a content preference of a first user, detecting based on the received meta data a plurality of pieces of recommended content similar to content that the first user is currently using, and outputting information regarding the respective pieces of detected recommended content.
Abstract:
Disclosed is a novel healthy and functional food having an obesity-suppressing activity. The healthy and functional food according to the present invention is manufactured by using an extract or a raw juice of purple-colored potato as a main/minor ingredient, or by adding the extract or a raw juice of purple-colored potato to various favorite foods. The extract of purple-colored potato according to the present invention has an obesity-suppressing activity by preventing an adipose cell from being differentiated and reducing leptin protein aiding to differentiate into adipose cells, and has an ability to reduce free fatty acid which is a hyperlipidemia-inducing factor and cholesterol in blood. Therefore, the healthy and functional food containing the extract of purple-colored potato according to the present invention can be useful to treat obesity patients including a wide age group of teenagers and adults and old persons.
Abstract:
A method and an apparatus to handover a mobile node between heterogeneous networks using a mobile internet protocol (IP) is provided. The method includes: connecting a mobile node to a movement destination network; obtaining information regarding, or about, the movement destination network; generating a message including the information regarding the movement destination network; and transmitting the generated message to a correspondent node that transmits continuous data to the mobile node.
Abstract:
A method and system establish a bi-directional tunnel through direct communication between a tunnel end point (TEP) and a user node without user assistance. The method includes: operating the user node in order to establish the bi-directional tunnel, wherein operating the user node includes: requesting network information necessary for establishing the bi-directional tunnel to the DHCP server; when the user node receives the network information from the DHCP server, establishing a unidirectional tunnel from the user node to the TEP based on the received network information; requesting one of the TEPs to establish the unidirectional tunnel; and when the user node receives a router advertisement (RA) message of a second network with which the user node wishes to communicate from the TEP required to establish the unidirectional tunnel, establishing an address of the user node in the second network.
Abstract:
Communication handover methods and apparatuses for use in an environment involving terminals having mobile nodes moving at a high speed. The handover method includes actively requesting handover to an access router based on the moving speed of a mobile node. The handover methods and apparatuses reduce handover latency and packet losses in a handover process of a terminal moving at a high speed.
