METHOD AND DEVICE FOR DIFFERENTIALLY MEASURING POSITION USING ACCESS POINT

摘要

Provided are a method and a device for measuring a position, in which a differential position measuring service is provided to measure a position of a communication terminal by using an access point for a wireless LAN service. Said method comprises the steps of: storing positional coordinates of access points; receiving service ranking information and information on peripheral access points from said communication terminal; selecting a predetermined number of peripheral access points on the basis of said service ranking information and said information on the peripheral access points; obtaining positional coordinates of each of said selected peripheral access point; calculating central coordinates by using said obtained positional coordinates of at least two access points of said selected access points; and determining the calculated central coordinates as a final position of said communication terminal.
