Abstract
A communication terminal () propagates a distance packet, and the distance packet is transmitted to a location identification apparatus () via an access point (). The distance packet includes a start-point distance, an end-point distance, and a terminal distance. The start-point distance is a distance between a start-point terminal and a start-point point, which is an access point detected by the start-point terminal. The end-point distance is a distance between an end-point terminal and an end-point point, which is an access point detected by the end-point terminal. The terminal distance is a distance between each other of communication terminals. The location identification apparatus identifies a location of each communication terminal based on distances included in the distance packet, coordinate values of the start-point point, and coordinate values of the end-point point.
