摘要:
A positioning method and apparatus of an electronic device which comprises a Global Navigation Satellite System (GNSS) or Global Positioning System (GPS), and an Inertial Navigation System (INS), includes receiving a satellite signal through the GNSS. A location of the electronic device and a reliability of location information of the electronic device is determined based on the satellite signal provided by the GNSS using at least one of satellite information of the satellite signal and location information based on the determined location of the electronic device. An operational level of the INS is determined using the reliability of the location information of the electronic device; and compensating the location of the electronic device by operating the INS according to the determined operational level of the INS.
摘要:
A portable terminal includes an apparatus for improving motion detection capability. Mo re particularly, the apparatus improves motion detection capability by changing a motion in a normal state according to a motion state or by changing a motion detection process in the portable terminal in order to avoid motion detection capability deterioration in the portable terminal are provided. The apparatus includes a terminal state determiner that determines a motion state of the terminal by receiving sensing information for determining the motion state, and a controller that changes a motion detection process according to the portable terminal's motion state determined by the terminal state determiner.

A wireless access point location positioning method and terminal operation method for floor information update. A method includes a terminal acquiring absolute location information, and transmitting surrounding Access Point (AP) signal information of an absolute location, together with the absolute location information, to a location server. The location server includes receiving surrounding AP signal information of the absolute location and associated atmospheric pressure information thereof, together with the absolute location information, from a terminal, determining locations of APs based on the received absolute location information and the surrounding AP signal information of the absolute location, and updating a related AP location using the determined locations of the APs.

A multimedia service system includes a portable terminal that communicates with a server. When a portable terminal is located at or within a building, the portable terminal acquires floor information of the building from a server, calculates a present altitude itself, determines a floor corresponding to the calculated altitude from the floor information, receives a multimedia service for the detected floor from the server, and outputs the received multimedia service. The server provides altitude-by-altitude floor information of the building and a floor-by-floor multimedia service to the portable terminal.
