A plurality of state communication channels are provided within a predetermined communication channel, and each of the state communication channels has an out channel for transmitting control signals between the terminal device and the switching device, and an in channel for transmitting communication information between the terminal devices. In a composite communication system that performs a plurality of communications using the predetermined communication channel, by providing a channel, the control signal transmitted via the out channel in the -mode communication channel is transmitted to other channels belonging to the same communication channel. A composite communication method characterized by providing a means for transmitting data via an in-channel within a communication path.
