Abstract:
A mobile node transmits a frame requesting IP address allocation information needed to obtain an IP address in a neighboring network; receives a frame including the IP address allocation information requested in the transmitted frame; and obtains an IP address in the neighboring network based on the IP address allocation information in the received frame to move to the neighboring network.
Abstract:
PURPOSE: An image searching method using a unique identifier of meta data and apparatus thereof are provided to search for an original image in a device through a feature value of an image. CONSTITUTION: It is determined whether a unique identifier exists in meta data of an input image(620). A unique identifier searches for an original image in a target device through the unique identifier(630). A feature value of the input image is extracted in case the unique identifier does not exist(640). The original image is searched for by comparing a feature value of the image(650).
Abstract:
PURPOSE: A data display method and device thereof are provided to efficiently arrange and display search data by arranging search data to be corresponded to a coordinate axis. CONSTITUTION: A search unit searches for a target content. The target content is matched with first coordinate information and second coordinate information. A controller(130) shows the target content corresponding to first and second coordinates. The search unit includes a keyword determining unit that determines a search keyword, a first searching unit(124) that searches for keyword related content, and a second searing unit(126) that searches for the target content.
Abstract:
PURPOSE: A service providing device and recommendation method are provided to rapidly supply a related service by using a user metadata. CONSTITUTION: A receiver(1210) receives content meta data. Based on received content metadata and at least one user metadata, a controller(1230) determines a related service and provided the determined related service. A display unit(1250) displays an UI(User Interface) for designating at least one user metadata. The controller combines the determined content metadata and a user metadata appointed from the UI to determine the related service. The controller searches the related service to display a web page for providing the searched related service.
Abstract:
PURPOSE: A content providing method and electronic device applying the same are provided to optimally utilize devices which a user owns by supplying content to an electronic device based on the attribute of content. CONSTITUTION: An electronic book requests the content purchase to a CP server(S310). After CP server generates an authentication key, the authentication key is transmitted to a mobile phone(S320). The user inputs the authentication key which is received to the mobile phone to the electronic book. The electronic book returns the authentication key to the CP server(S330). The CP server determines a device that transmits content based on content attribute(S340).
Abstract:
PURPOSE: A display apparatus for supporting a search service, a user terminal for performing a search of object, and a method thereof are provided to enable a user to easily search for a desirable object. CONSTITUTION: A screen is displayed(S710), and an object is selected from the screen. A request for searching the object is received(S720). Terminal location related information is received from a user terminal device(S730), and the location information adaptive to the user terminal device is provided to the user terminal device(S740).
Abstract:
PURPOSE: A method and a device for recommending content are provided to recommend at least one of contents to the first user through the searched second users. CONSTITUTION: A temporary contents preference information is generated by using a inputted keyword from the first user and content preference information of the first user(110). The second user is searched at a P2P network. The second users have similar contents preference with content preference of the first user. At least one of content is recommended to the first user through the searched second user(120).
Abstract:
이종망간에 데이터 통신이 가능한 터널 서비스를 제공하는 시스템이 개시된다. 본 발명에 따른 사용자 노드에 터널 라우터의 주소를 설정하는 방법은, 터널 서비스 지원 서버로 적어도 하나의 터널 라우터의 주소를 요청하는 메시지를 전송하는 단계; 상기 터널 서비스 지원 서버로부터 상기 적어도 하나의 터널 라우터의 주소를 포함하는 메시지를 수신하는 단계; 및 상기 수신한 메시지에 포함된 터널 라우터의 주소를 저장하는 단계를 포함한다. 본 발명에 의하면, 사용자 노드에 터널 서비스를 제공하는 터널 라우터의 주소를 보다 간편하게 설정할 수 있고, 터널 라우터의 주소가 변경되거나 새로운 터널 라우터가 추가되더라도 사용자가 수동으로 터널 라우터의 주소를 변경할 필요없이 터널 라우터의 주소를 간편하게 설정할 수 있다.
Abstract:
본 발명은 서로 다른 통신 규격들을 따르는 다양한 통신망들이 혼재된 환경에서 고속으로 핸드오버를 수행하는 장치 및 방법에 관한 것으로, 본 발명에 따른, 이종 망들 사이를 이동하는 이동 노드에서의 제 1 핸드 오버 수행 방법은 이동 노드를 제 1 종 망에 연결하는 노드로부터 수신된 신호가 이동 노드가 제 1 종 망으로부터 제 2 종 망으로 이동하고 있음을 나타내는 망 정보를 포함하는 지를 확인하는 단계; 및 확인에 기초하여 이동 노드가 위치한 망의 종류의 변경에 따른 핸드오버를 선택적으로 수행하는 단계를 포함하며, 이동 노드가 새로운 망으로 이동하고 있음을 예측하게 할 수 있게 함으로써 미리 핸드오버를 준비하여 보다 고속의 핸드오버를 수행할 수 있다.
Abstract:
A method and an apparatus of performing handover of a mobile terminal to reduce the latency for setting address are provided to prevent unnecessary latency in new network and to compare a first information and a second information by receiving the second information about an IP address set up method. A first information about an IP(Internet Protocol) address establishment mode used in the new network of the hand over next is received from an IS(Information Server) in advance(110). While connecting the new network, the second information about the IP address establishment mode is received from PoA(Point of Attachment) of the new network(120). It determines whether the first information and the second information are identical(130). In case the first information and the second information are identical, IP address is set up according to the first information(140).
