PURPOSE: To realize the selection system for a radio channel for a radio system and a transfer system of a selected channel to each terminal in a group.
CONSTITUTION: A radio terminal equipment has a diffusion code generator 12 supplying a selected diffusion code to a transceiver 16, a pilot code generator 11 supplying a pilot code to the transceiver 16, a network controller 15 and a channel controller 13 controlling the output of the pilot code, the selected diffusion code output and the diffusion code used by the transceiver 16 and the transmission reception of them. Then a diffusion code (pilot code) for controlling a communication channel in common to the system is provided and the pilot signal is intermittently sent to an optional radio terminal (host terminal) belonging to each group and the selection of the diffusion code used for each group and the selection of each membership belonging to each group are sent in terms of code.
