Abstract

PURPOSE:To enable to increase or decrease the sub-system number without changing the functions of the unit with economized entire system, by constituting the operation of the entire system through mutual communication of each sub-system. CONSTITUTION:When the base station 1-1 of the sub-system 1 is finished for the data collection and hopes to give the right of usage of radio channel to the sub- system 2, the base station 1-1 controls 4 the selection switches 5, 6, to select the connection from the transmitter 7 and receiver 9 to the transmitter 8 and the receiver 10, and interruption request command is delivered to the base station 2-1 of the sub-system 2 through the setting of the same transmission and reception frequency as the same as the terminal unit. Since in the sub-systems 2, 3, the receiver 9 of the base stations 2-1, 3-1 is operated in reception frequency F2 and waiting at the monitoring mode, if the channel usage right is absent to the sub-systems 2 and 3 themselves, the base station 2-1 returns the response signal when the interruption request from 1-1 is received to start the service in the sub-system 2.
