Abstract
The present disclosure relates to providing a positioning service by managing a plurality of peripheral wireless LAN signals. The positioning service system collects peripheral wireless LAN radio signals by scanning peripheral access points (APs), stores AP information of each of peripheral wireless LAN radio signals in each lattice cell of a database. When a positioning request signal is received from a terminal, a positioning server of the positioning service extracts AP identification information from included in the peripheral wireless LAN radio signal received from the terminal. By using the extracted AP identification information, the positioning server selects from the database the corresponding lattice cell matching to the stored AP identification information of each of the peripheral wireless LAN radio signals pre-stored. And the positioning server estimates location information of the selected corresponding lattice cell as location information for the terminal.
