Patent ID: 8644859

Claim:
An apparatus to provide an augmented reality (AR) service using location-based information in a user terminal communicating with a plurality of base stations (BSs) allocated to at least one cell among a plurality of cells in an area, the apparatus comprising: a camera to capture an image; a controller, of the user terminal, to: obtain first location information of the camera using locations of the BSs to identify a cell where the camera is located, receive feature point information from image patches corresponding to the identified cell, from at least one BS allocated to the identified cell, detect an updated first location of the camera by matching data of the received feature points to data of the image, and provide location-based information in a same direction as the captured image according to the updated first location of the camera; a transceiver to communicate with the plurality of BSs, wherein the controller searches for a connectable BS among the plurality of BSs through the transceiver, receives location information about all found BSs, and detects a location of the user terminal based on the location information; and a display to provide an AR service by combining the captured image with the location-based information under control of the controller.
