Abstract
Methods and apparatus are provided for measuring a position of a mobile terminal. A first position is calculated by using a GPS signal. A visible light communication mode of the mobile terminal is activated, when the first position exceeds a predetermined error range. Visible light communication device position information is received. A third position is calculated by using a second position, which corresponds to a position prior to the first position, and the visible light communication device position information.
Claims12
A method of measuring a position of a mobile terminal, comprising the steps of:
- calculating a first position by using a GPS signal;
- activating a visible light communication mode of the mobile terminal, when the first position exceeds a predetermined error range;
- receiving visible light communication device position information;
- and
- calculating a third position by using a second position, which corresponds to a position prior to the first position, and the visible light communication device position information.
An apparatus for measuring a position, comprising:
- a GPS receiver for receiving a GPS signal;
- a GPS position calculator for measuring a first position by using the GPS signal;
- a visible light signal transceiver for transmitting and receiving a visible light signal;
- a visible light communication device position calculator for calculating a position of a visible light communication device by using visible light communication device position information received through the visible light signal transceiver;
- a position calculator for, when the first position exceeds a predetermined error range, calculating a third position by using a second position, which corresponds to a position prior to the first position, and the position of the visible light communication device;
- and
- a controller for activating a visible light communication mode when the first position exceeds the predetermined error range, and controlling the position calculator to calculate the third position.
