20150189478 | APPARATUS AND METHOD FOR LOADING RADIOMAP DATABASE, AND TERMINAL DEVICE - An apparatus and method for loading a radiomap database (DB) and a terminal device are disclosed. The apparatus for loading a radiomap DB includes a moving information calculation unit, and a loading performance unit. The moving information calculation unit calculates the moving information of a terminal based on the difference between a previous location and estimated final location of the terminal as the terminal moves. The loading performance unit loads a radiomap DB, including information about a neighboring node of each reference point, and a radiomap DB, including information about a neighboring node of a reference point, located in a direction in which the terminal moves, based on the moving information calculated by the moving information calculation unit. | 07-02-2015 |
