Patent ID: 7546111

Claim:
A mobile communication system, comprising: a wireless base station that measures the strength of radio waves received from a wireless terminal irrespective of whether or not the destination of the radio waves is the wireless base station itself; a communication network that communicably connects between said wireless base station and other wireless base stations; and a controller that creates a terminal management table that contains identification information on said wireless base station itself that measures the radio wave strength, identification information on said wireless base station corresponding to the destination of the radio waves, identification information on said wireless terminal that transmits the radio waves, and the radio wave strength measurement result, and that combines the terminal management table thus created and terminal management tables received from said other wireless base stations by using said communication network, wherein the controller has a relative position identification function that identifies the relative positional relationship of a plurality of wireless base stations by using the combined terminal management table, wherein the controller searches data in which identification information on the wireless base station that measured the radio wave strength is self-identification information, from the combined terminal management table; reads identification information on the wireless terminal from the searched data; reads data containing the read wireless terminal identification information from the combined terminal management table; reads identification information on the wireless base station that measured the radio wave strength from the data thus read; and judges that the wireless base station corresponding with the wireless base station identification information thus read is an adjoining wireless base station.
