Abstract

PURPOSE:To improve the line use efficiency, by reducing the number of adjacent communication zones, which block the same channel, according to the operating time band, in the mobile communication system constituted by plural base stations and plural mobile stations. CONSTITUTION:The calling signal which is received through antenna ANT of base station ES of zone E out of plural base stations arrnged in series reaches control office MS and is connected to the telephone set by the transmitter on the car. At this time, in control office MS, the relay corresponding to zone E is operated, and contact (e) is turned on to block the same channel of force 6 zones and hind 4 zones of the train. At the time band set by clock circuit CL, relay NO is operated by the driving output of driver DR, and contact no is opened, and therefore, blocking zones are only zones D and F adjacent to zone E.
