LOCATION MEASURING METHOD AND APPARATUS USING ACCESS POINT FOR WIRELESS LOCAL AREA NETWORK SERVICE
First Claim
1. A method for measuring a location of a communication terminal using a plurality of access points, the method comprising:
- storing access point information collected at a plurality of locations;
extracting information of nearby access points collected together at a location of the plurality of locations, where information of a reference access point is collected, from the access point information;
calculating a barycentric coordinate using location coordinates of the nearby access points; and
determining the calculated barycentric coordinate as a final location of the communication terminal.

Abstract
A method and apparatus for measuring a location of a communication terminal using an access point for a wireless local area network service is provided. The method includes storing access point information collected at each location, extracting information of nearby access points collected together at a location, where information of a reference access point is collected, from the access point information, calculating a barycentric coordinate using location coordinates of the extracted nearby access points, and determining the calculated barycentric coordinate as a final location of the communication terminal.

10. A method for measuring a location of a communication terminal using an access point, the method comprising:
-
storing access point information collected at a plurality of locations; extracting information of a reference access point from the access point information; classifying collection location coordinates among the extracted information of the reference access point into a plurality of categories; calculating barycentric coordinates using the collection location coordinates of the plurality of categories; and determining a final barycentric coordinate based on the calculated barycentric coordinates, as a final location of the communication terminal. - View Dependent Claims (11)
