Abstract
A method for measuring a location of a mobile terminal includes calculating first location information by using a ToA (Time of Arrival) scheme, calibrating the first location information by using angle information between two base stations and the terminal; calculating second location information by using an AoA (Angle of Arrival) scheme, and calculating a location value of the terminal by using the calibrated first location information and the second location information.
Claims11
A method for measuring a location of a mobile terminal, the method comprising:
- calculating first location information by using a Time of Arrival (ToA) scheme;
- calibrating the first location information by using angle information between two base stations and the terminal;
- calculating second location information by using an Angle of Arrival (AoA) scheme;
- and
- calculating a location value of the terminal by using the calibrated first location information and the second location information,
- wherein the first location information is calibrated by using a sine value of the angle information between the two base stations and the terminal.
A method for measuring a location of a mobile terminal, the method comprising:
- calculating distance information between each of three base stations and the terminal by using a Time of Arrival (ToA) with respect to the three base stations adjacent to the terminal;
- correcting the distance information by using angle information between each of the base stations and the terminal;
- and
- calculating a location value of the terminal by using the corrected distance information,
- wherein the distance information is corrected by using a sine value of the angle information between each of the base stations and the terminal.
