Embodiment Construction

[0085] The present invention will be described below by using specific embodiments shown with reference to the drawings, but the present invention is not limited to the embodiments to be described later. A business constructs a network as follows: constructing a small-scale network in a floor area of ​​a building by using a LAN; constructing a medium-scale network in a building by connecting the small-scale network using a communication device (router) that interconnects the small-scale networks; and The Internet, wide-area Ethernet, and wide-area network (WAN) are connected to networks constructed by distant factories, branch offices, and affiliated companies to build a corporate network environment.

[0086] The position estimation system of the present invention is suitable for such a company network environment, for example. Even in an indoor environment where GPS radio waves are unreceivable, the position estimation system can easily estimate in which area, on which floor...

Abstract

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.

Description

technical field [0001] The present invention relates to a system for estimating positions of corresponding information communication terminals, an information communication terminal used in the system, an agent program, and a position estimating method for the system. More specifically, the present invention relates to: a system for estimating the position of a corresponding information communication terminal connected to a wireless LAN based on a position of a pseudo access point, which is an information communication terminal connected to a wired LAN; An information communication terminal used in the system; an agent program implemented in each of the information communication terminals; and a position estimation method used in the system. Background technique [0002] As portable information communication terminals such as mobile phones, smart phones, tablet PCs, and notebook PCs have come into widespread use, users have come to always carry such information communication...
