20100085893 | SENSOR NODES IN MULTIPLE SENSOR NETWORK, METHOD FOR CREATING GRID-BASED TREE OF SENSOR NODES AND SPATIAL QUERY PROCESSING SYSTEM USING GRID-BASED TREE - A method for creating a grid-based tree in a multiple sensor network includes: dividing an entire area in which a base station node and a plurality of sensor nodes are disposed into grid areas; assigning a grid ID to each of the grid areas; setting, sequentially from the base station node to each of the sensor node, level information, candidate child nodes and candidate parent nodes; storing a grid ID of a grid area in which the respective nodes locate; selecting, for the respective sensor nodes, a parent node based on the grid ID, the level information, and the candidate parent nodes; and calculating, for the respective nodes, minimum bounding rectangles each of which includes a child node of corresponding node and nodes descended from the child node. The grid-based tree is calculated by using the minimum bounding rectangles. | 04-08-2010 |
20100138151 | ROUTE GUIDE SYSTEM AND METHOD USING STATE INFORMATION OF POI - A route guide method includes collecting state information of respective points of interest (POIs) and storing the collected state information in a state information database, extracting state information of one or more candidate POIs with reference to the state information database according to a request for the state information of the one or more candidate POIs, and applying the extracted state information of the candidate POIs to routes to the respective POIs to guide a user along the routes to the respective candidate POIs. | 06-03-2010 |
20110110287 | NAVIGATION TERMINAL, METHOD AND SYSTEM FOR UPDATING MAP VIA FUSION OF BROADCASTING AND TELECOMMUNICATIONS - A method for updating a map in a navigation terminal via fusion of broadcasting and telecommunications includes: receiving map contents of the map from a broadcast center via a broadcast network; classifying the map contents received via the broadcast network into updatable map contents and un-updatable map contents which have dependencies with map contents having not been received by the navigation terminal; and updating the map using the updatable map contents. The method further includes requesting the broadcast center via a wired/wireless telecommunications network to download map contents of the map, which have not been received but have dependencies with the un-updatable map contents; receiving the requested map contents from the broadcast center via the wired/wireless telecommunications network; and updating the map by aggregating the un-updatable map contents with the requested map contents. | 05-12-2011 |
20110153276 | APPARATUS AND METHOD FOR PROVIDING COMPOSITE SENSOR INFORMATION - Disclosed herein is an apparatus and method for providing composite sensor information. The apparatus receives sensor information from a plurality of sensors and creating a virtual sensor as a proxy for a plurality of effective sensors included in a region requested to be searched from a user terminal. Thereafter, the apparatus creates composite sensor information by fusing a plurality of the sensor information corresponding to the plurality of effective sensors included in the virtual sensor. | 06-23-2011 |
20110153655 | SERVER-SENSOR NETWORK COOPERATIVE SPATIAL QUERY PROCESSING METHOD AND SERVER USING THE SAME - Disclosed herein are a server-sensor network cooperative spatial query processing method and a server using the method. The server-sensor network cooperative spatial query processing method includes the server detecting supplementary information for selecting sensor nodes to be excluded from among a plurality of sensor nodes by performing a preliminary spatial query, before starting a spatial query with the plurality of sensor nodes, and the server requesting the spatial query to the sensor nodes, selected based on the supplementary information, when starting the spatial query with the plurality of sensor nodes. | 06-23-2011 |
20110225194 | APPARATUS AND METHOD FOR ANALYZING INFORMATION ABOUT FLOATING POPULATION - Disclosed herein is an apparatus and method for analyzing information about floating population. The apparatus includes an information collection unit, a data integration unit, a data mining analysis unit, and an interface unit. The information collection unit collects information about locations provided by mobile communication terminals of moving objects, information about attributes of the moving objects, and information about locations and attributes related to stationary objects. The data integration unit creates integrated data by integrating the information collected by the information collection unit, national statistical information, and map data registered previously. The data mining analysis unit extracts data, consistent with conditions input by a system user, from the integrated data, and searches the map data for based moving patterns of the moving objects using data mining analysis. The interface unit provides a map service in which search results have been applied to the map data. | 09-15-2011 |
20120122476 | METHOD AND SYSTEM FOR PROVIDING SPATIAL-BASED CONTEXT-AWARE SERVICE - A system for providing spatial-based context-aware service includes a database configured to store a geocontext including spatial information, one or more contexts, and sensor data; a sensor/context catalog server configured to manage meta data of the contexts and the sensor data; a context processing server configured to generate a list of contexts applicable to the mobile device based on the sensor data and the meta data upon a receipt of the sensor data from the mobile device; a geocontext search server configured to search the database for candidate geocontexts appropriate for the user of the mobile device by using the location information of the mobile device and the list of contexts; and a context-aware management server configured to generate a list of recommended services by executing the searched candidate geocontexts. | 05-17-2012 |
20120143691 | SYSTEM AND METHOD FOR PROVIDING USER-SPECIFIC ADVERTISEMENT ON BASIS OF M2M COMMUNICATION, AND MOBILE TERMINAL - Provided are a system and method for providing a user-specific advertisement on the basis of machine-to-machine (M2M) communication, and a mobile terminal. The method includes: receiving an advertising message broadcasted from at least one mobile terminal; extracting an advertisement according to a user situation using profile information set by a user of the mobile terminal; and presenting and displaying the extracted advertisement. | 06-07-2012 |
