Method and apparatus for providing differential location-based service using access point

Abstract

A location detecting method and an apparatus for providing a differential location-based service to detect a location of a communication terminal using an access point for a wireless local area network service is provided. The method includes storing location coordinates of access points, receiving service grade information and information related to nearby access points from the communication terminal, selecting a predetermined number of nearby access points based on the received service grade information and information of nearby access points, obtaining a location coordinate of each of the selected nearby access points, and calculating a centric coordinate using the obtained location coordinates of at least two of the selected access points, and determining the calculated centric coordinate as the detected location of the communication terminal.
