METHOD AND DEVICE FOR CONNECTING COMMUNICATION LINE FOR PERSONAL HANDYPHONE SYSTEM

摘要

PROBLEM TO BE SOLVED: To utilize a personal handyphone system(PHS) inside a high-speed moving object. SOLUTION: A radio base station 19 connected with a public line network is installed on the ground. The cover area of the radio base station 19 is sufficiently widened while considering the moving speed and moving range of the high-speed moving object. On the other hand, the high-speed moving object 1 is provided with a mobile station 7. A PHS 3 inside the high-speed moving object 1 and the public line network are connected through the radio base station 19 and the mobile station 7. Since the PHS 3 is provided with a mode on the assumption of use inside the high-speed moving object, the PHS 3 inside the high-speed moving object 1 is prevented from being directly connected with the ground station.
