Mobile communication system
First Claim
1. A mobile communication system including a plurality of base stations positioned within a communication area each for emitting a radio wave inherent thereto and a mobile station moving within the communication area and communicating with the respectives of the base stations via the transmitted radio waves, said system comprising:
- location correlation data group storing means for previously storing a location correlation data group including correlation datas respectively representing correlation situation of a plurality of arriving radio waves produced by the transmitted radio waves at respectives of a plurality of sampling locations within the communication area as location correlation datas respectively corresponding to the locations;
current correlation data calculating means for receiving the arriving radio waves at a current position of the mobile station and calculating current correlation datas respectively representing the correlation situations among the arriving radio waves for the respective mobile stations; and
current position determining means for comparing the location correlation data in the location correlation data group and the current correlation data and determining the current position of the mobile station in accordance with a result of the comparison thereby to generate information of the determined current position.

Abstract
A mobile communication system including a plurality of base stations arranged in a communication area each for emitting a radio wave inherent thereto and a mobile station moving in the communication area and communicating with respectives of the base stations via the transmitted radio waves. There is previously stored a location correlation data group including correlation data representing correlation situations of a plurality of arriving radio waves produced by the transmitted radio waves at respectives ones of a plurality of sampling locations within the communication area as location correlation data in correspondence with the respective locations. Upon reception of the arriving radio waves at a current location of the mobile station, there is calculated current correlation data representing correlation situations among the received arriving radio waves for the respective mobile station. There are compared the location correlation data in the location correlation data group and the current correlation data, and then the current position of the mobile station is determined in accordance with a result of the comparison and the determined current position data is generated.
