Abstract:
Provided are a method, device and system for estimating the location of a user device by using radio signals emitted from access point (AP) devices. In the location estimating method implemented by the user device may include steps of measuring received signal strength of a signal received from two or more AP devices deployed within a specific range, establishing a binding box for each of the two or more AP devices by using the measured received signal strength, and estimating a current location of the user device by using points of contact between the established binding boxes.

Claim (Index 1):
A location estimating method implemented by a user device, the method comprising:\n determining whether the user device enters a building; when it is determined that the user device enters the building, setting a current altitude value as a reference point for location estimation; setting inter-floor information based on information corresponding to an average inter-floor height of the building or past information corresponding to an altitude distribution for each floor of the building; and computing a user-located floor based on the current altitude value, the reference point, and the inter-floor information.
