Abstract
A method for estimating a location of a mobile device located in means of transportation is provided. The method includes: developing a first database by linking ID information of the means of transportation with ID information of an access point (AP) installed in the means of transportation, the AP being a mobile AP allowing access to a wireless WAN through WiFi; developing a second database by linking ID information of the means of transportation with service information of the means of transportation, the service information including route and timetable information; acquiring WiFi reception information generated by the mobile device equipped with a WiFi module, the WiFi reception information including ID information of an AP transmitting a WiFi signal; extracting the ID information of the means of transportation in which the mobile device is located using the acquired WiFi reception information and the first database; and estimating a location of the mobile device using the extracted ID information of the means of transportation and the second database.
