Abstract

See full text

A positioning system and a position calculating method in a mobile communication system for specifying a position of a mobile station unit on the basis of positional information from three base station units and for displaying related map information on the mobile station unit to utilize the positional information effectively, the position system and the position calculating method in which a position reporting means of a base station unit reports positional information, a distance difference calculating means of the mobile station unit calculates differences in distance between the mobile station unit and three base station units on the basis of the positional information from the three base station units, measures a position of the mobile station unit on the basis of the positional information and the distance differences by using a position measuring means, reports the measured position to an exchange unit by using a position reporting means, and a map information displaying means of the mobile station unit displays related map information reported from the exchange unit.
