PORTABLE TERMINAL EXISTENCE REGION ESTIMATION DEVICE, PORTABLE TERMINAL EXISTENCE REGION PROVIDING SYSTEM AND PORTABLE TERMINAL EXISTENCE REGION ESTIMATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To acquire a portable terminal existence region providing system capable of estimating a region in which a portable terminal and the like is currently located with good accuracy by using reception intensity of a received beacon signal irrespective of the number of access points and the degree of the reception intensity of the beacon signal, without performing complex geometric calculation processing.;SOLUTION: A portable terminal existence region providing system is constituted by a plurality of access points APk indoors, a portable terminal 10 and a server 100 of a service center. The server 100 acquires a portable terminal existence high probability region SRk in which the portable terminal 10 currently exists by using AP reception intensity AEk even when the AP reception intensity AEk of AP identification information APCk from the access point APk from the portable terminal 10 is equal to or less than a reference value level.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
