Title:
MOBILE TERMINAL, POSITION DISCRIMINATION SERVER, ACCESS POINT, INDOOR POSITIONING SYSTEM, AND POSITIONING METHOD USING MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/235361
Kind Code:
A1
Abstract:
The present invention realizes a mobile terminal capable of detecting a current position indoors, even in an environment in which indoor positioning cannot be adequately performed using an indoor wireless signal compatible with a GPS signal. A mobile terminal (1) which can communicate mutually with at least one indoor position information transmitter (IMES transmitter 4a-4d) and at least one access point (2a, 2b) comprises an indoor positioning unit (23) that, when the magnetic field strength of a wireless signal received from the indoor position information transmitter is less than a prescribed threshold value, sets, as the current position of the mobile terminal itself, position information of an access point determined to be present near the mobile terminal.
