Abstract
Measuring a location of a communication terminal using a wireless local area access point based on location coordinates of the access points and location information of a nearby lamp.
Claims17
A method of measuring a location of a communication terminal, the method comprising:
- storing location coordinates of a plurality of access points and a location coordinate of a lamp in a storage unit;
- receiving from the communication terminal identity information that identifies nearby access points from among the plurality of access points and identity information that identifies the lamp;
- extracting a location coordinate of each of the nearby access points from the storage unit, and calculating the location of the communication terminal using the extracted location coordinates;
- and
- correcting the calculated location using the location coordinate of the lamp, as a final location coordinate of the communication terminal,
- wherein the correcting comprises:
- selecting a correction ratio based on a number of extracted location coordinates;
- and
- determining a location coordinate where a straight line connecting a calculated location coordinate and the location coordinate of the lamp is divided into the correction ratio, as the final location coordinate of the communication terminal.

An apparatus for measuring a location of a communication terminal, the apparatus comprising:
- a storage unit that stores location coordinates of a plurality of access points and a location coordinate of a lamp;
- a receiver that receives from the communication terminal identity information that identifies nearby access points from among the plurality of access points and identity information that identifies the lamp;
- and
- a location determining unit that extracts the location coordinates of each of nearby access points among the plurality of access points from the storage unit, calculates the location of the communication terminal using the extracted location coordinates, and corrects the calculated location using the location coordinate of the lamp as a final location coordinate of the communication terminal,
- wherein the location determining unit selects a correction ratio based on a number of the extracted location coordinates and determines a location coordinate where a straight line connecting a calculated location coordinate and the location coordinate of the lamp is divided into the correction ratio, as the final location coordinate of the communication terminal.
