Abstract

PROBLEM TO BE SOLVED: To attain automatic selection of a transmission line capable of opti mum communication by allowing a mobile station to add prescribed area data and sending the resulting data to a base station so as to improve the selection precision of the transmission line. SOLUTION: A setting means 30 of a mobile station 1 sets position area data specified by crossing position of latitude and longitude and adds the data to communication data and sends the resulting data as a radio wave. A communication station 7 uses detection means 16, 17 to detect a signal error rate from base stations 4, 5 from a demodulated reception signal and gives the result to the error rate recognition section of a control means 33 and compares both the error rates to select automatically the optimum transmission path. When the error rate of each transmission line is identical or the error rate is lower than a prescribed value, position area data extract means 31, 32 use a selection means 50 to select a path via the base station 4 or 5 closest to the position area. Thus, selection precision of the transmission line via plural base stations is improved and a transmission line capable of optimum communication with the mobile station is selected.
