MOBILE DEVICE, LOCATION ESTIMATION METHOD, AND COMPUTER-READABLE RECORDING MEDIUM
First Claim
1. A mobile device comprising:
- a processor configured to execute a process including;
first estimating a location of each of a plurality of base station devices present at a location communicable with the mobile device;
generating a circle a radius of which is a distance between the mobile device and the base station device estimated by using radio wave intensity from the base station device, around the location of the base station device estimated at the first estimating, for each of the base station devices; and
second estimating a location of the mobile device by using algorithm selected based on the number of the circles of the base station devices generated at the generating and a location relation between the circles.

Abstract
A mobile device estimates includes a processor configured to execute a process. The process includes first estimating a location of each of a plurality of base station devices present at a location communicable with the mobile device. The process includes generating a circle a radius of which is a distance between the mobile device and the base station device estimated by using radio wave intensity from the base station device, around the location of the base station device estimated at the first estimating, for each of the base station devices. The process includes second estimating a location of the mobile device by using algorithm selected based on the number of the circles of the base station devices generated at the generating and a location relation between the circles.
