According to one embodiment of the present invention, a method for calculating the location of a terminal in a wireless communication system, which is to be performed by the terminal, comprises the steps of: transmitting, to a location server, a request for location estimation assist data for calculating the location of the terminal; receiving the location estimation assist data from the location server; and calculating the location of the terminal using the location estimation assist data. The location estimation assist data includes radio map information including a received signal strength (RSS) value from each access point collected at a plurality of location estimation reference points in a region having a predetermined range. The radio map includes information regarding the location estimation reference points (hereinafter, referred to as "update points") which require an update of the radio map. The method may further include a step of determining whether or not an update of the location estimation assist data is required based on the calculated location of the terminal and the information regarding the update points. |
