Information communication terminal, agent program, location estimation system and location estimation method

摘要

To provide a system capable of estimating a location of an information communication terminal and to provide an information communication terminal used for the system, a system includes multiple information communication terminals and a management server. Each information communication terminal has an agent program installed thereon. When the information communication terminal is connected to the wired LAN, an terminal information sending unit sends terminal identification information to cause the management server to generate location information. Upon receiving a mode change instruction, a communication mode changing unit changes a mode to cause the information communication terminal to function as a pseudo access point. When the information communication terminal is not connected to the wired LAN, a radio wave intensity measuring unit measures an intensity of the carrier wave from the PAP. The information communication terminal transmits a measurement result to the management server to cause the management server to estimate location information.
