Method and system for providing indoor positioning service
First Claim
1. An indoor positioning service providing method, performed by a processor, to determine a current location of a user terminal located inside a building, the method comprising:
- receiving a request for providing an indoor positioning service from the user terminal;
receiving information about adjacent wireless access points of the user terminal in response to the request;
calculating a similarity between information and another piece of information, and a location accuracy of a wireless access point based on the received information about the adjacent wireless access points of the user terminal and information about adjacent wireless access points collected from each of a plurality of virtual regions disposed inside the building; and
determining the current location of the user terminal based on the similarity between information and another piece of information, and the location accuracy;
wherein the calculating comprises;
determining a wireless access point that matches a media access control (MAC) address of an adjacent wireless access point of the user terminal, with respect to information about the adjacent wireless access points collected from each region; and
calculating the location accuracy for each corresponding, region based on at least one of a number of adjacent wireless access points collected from each corresponding virtual region and a number of the matching wireless access points, with respect to a virtual region corresponding to the wireless access point that matches the MAC address.
