Abstract
An apparatus for determining a position of a terminal calculates distances between a terminal and a plurality of base stations by using time information acquired by a reference station among the plurality of base stations through unidirectional communication between the terminal and the base stations and between the base stations, and determines a position of the terminal by using the calculated distances.
Claims12
A method for determining a position of a terminal, comprising:
- calculating distances between the terminal and a plurality of base stations by using time information acquired by a reference station among the plurality of base stations through unidirectional communication between the terminal and the plurality of base stations and between the plurality of base stations;
- and
- determining a position of the terminal by using the distances between the terminal and the plurality of base stations.
An apparatus for determining a position of a terminal, comprising:
- a distance calculating unit for calculating distances between the terminal and a plurality of base stations by using a plurality of first receiving time information data, a plurality of transmitting time information data, and a plurality of second receiving time information data, the plurality of first receiving time information data corresponding to times at which the plurality of base stations respectively receive a signal transmitted from the terminal, the plurality of transmitting time information data corresponding to times at which base stations, excluding a reference base station, among the plurality of base stations respectively transmit the received first receiving time information data to the terminal, and the plurality of second receiving time information data corresponding to times at which the reference station receives the first receiving times of the base stations;
- and
- a position determining unit for determining a position of the terminal by using the distances between the terminal and the plurality of base stations.
A method for determining a position of a terminal, comprising:
- receiving a plurality of receiving time information data corresponding to times at which a plurality of base stations respectively receive a signal transmitted from the terminal;
- receiving a plurality of transmitting time information data corresponding to times at which a plurality of first base stations, excluding a reference station, among the plurality of base stations respectively transmit the corresponding first receiving time information to the reference station;
- receiving a plurality of second receiving time information data corresponding to times at which the reference station receives transmitting time information of each of the plurality of first base stations;
- calculating distances between the terminal and the plurality of base stations by using the plurality of first receiving time information data, the plurality of transmitting time information data, and the plurality of second receiving time information data;
- and
- determining a position of the terminal by using the distances between the terminal and the plurality of base stations.
