Document Type and Number:

WIPO Patent Application WO/2012/074309

Kind Code:

A2

Abstract:

Provided are a method and apparatus for measuring the position of a communication terminal based on position coordinates of access points and GPS information on the communication terminal. The method comprises: a storing step of storing position coordinates of a plurality of access points in a storage unit; a receiving step of receiving GPS information on the communication terminal from the communication terminal and extracting position coordinates from the storage unit; a calculating step of calculating the position of the communication terminal using the extracted position coordinates; and a correcting step of correcting the calculated position based on the GPS information so as to obtain final position coordinates of the communication terminal.
