Terminal and method for measuring location thereof
First Claim
1. A method for measuring a location of a terminal, the method comprising:
- peforming a first location estimating operation including;
measuring received signal strength indicator (RSSI) values of signals received from a plurality of electronic devices located in a space;
extracting a plurality of preliminary locations of the terminal corresponding to a plurality of algorithms, respectively, by applying the plurality of algorithms to the measured RSSI values;
determining a first location of the terminal by applying a plurality of predetermined weights corresponding to the plurality of algorithms to the plurality of preliminary locations corresponding to the plurality of algorithms; and
determining whether to perform a second location estimating operation of the terminal, based on the first location;
determining a final location of the terminal based on the first location, if it is determined not to perform the second location estimating operation; and
determining the final location of the terminal based on the first location and the second location, if it is determined to perform the second location estimating operation,wherein the second location is determined based on an output of at least one sensor.

Abstract
A user terminal measures a location thereof. In a method for measuring a terminal location, the terminal measures received signal strength indicator (RSSI) values of signals received from a plurality of electronic devices deployed in a space. Then the terminal extracts a preliminary location of the terminal with respect to each of a plurality of predetermined algorithms by applying the plurality of algorithms to the measured RSSI values, identifies a first estimated location of the terminal by applying a predetermined weight to each preliminary location, identifies a second estimated location of the terminal using an output of at least one sensor, and determines a final location of the terminal, based on the first and second estimated locations.
