1. A wireless LAN AP position value positioning method for continuously updating a position value of a wireless LAN AP to an accurate value, the wireless LAN AP position value positioning method comprising:
(a) a wireless LAN AP information and position transmission step at which a wireless LAN AP information and position detection device for a nearby wireless LAN AP detects wireless LAN AP information, including identification information of a wireless LAN AP and signal strength information, and a detection position, which is a position at which the wireless LAN AP information is detected, from each of nearby wireless LAN APs, and transmits the detected wireless LAN AP information and detection position information to a positioning server having a wireless LAN AP position database configured to record a position value of the wireless LAN AP and a signal strength of the wireless LAN AP at the position value in accordance with the identification information of the wireless LAN AP;
(b) a common wireless LAN AP checking step at which the positioning server checks for common wireless LAN APs by comparing the identification information of the wireless LAN APs of the transmitted wireless LAN AP information with the wireless LAN AP position database, the common wireless LAN APs being the transmitted wireless LAN APs having a common media access control (MAC) address with APs in the wireless LAN AP position database, respectively, and being used to determine whether the wireless LAN AP position database is updated;
(c) a signal strength comparison step at which the positioning server compares a signal strength of the transmitted wireless LAN AP information and a signal strength of the wireless LAN AP position database for each of the common wireless LAN APs; and
(d) a wireless LAN AP position database update step at which, if, as a result of the comparison between the signal strengths, the signal strength of the transmitted wireless LAN AP information is higher, the positioning server replaces the position value and signal strength of the corresponding wireless LAN AP of the wireless LAN AP position database with the transmitted detection position and signal strength of the wireless LAN AP information.
