Abstract:
A radio transmission control method for conducting communication on a predetermined radio transmission channel using asynchronous transmission under control of a control station in a wireless radio network including one control station and a plurality of wireless communication stations capable of radio communicating with the control station, said radio transmission control method comprising the steps of:inhibiting a polling operation conducted from said control station to each communication station on the network by bringing each communication station on the network into a dormant state so as to reduce power consumption of each communication station in the dormant state; transmitting a request signal to said control station when a transmission demand has occurred in each of said plurality of communication stations and bringing said plurality of communication stations into an operation state from the dormant state upon the occurrence of the transmission demand; and starting to conduct the polling operation conducted from the control station when the control station has received the polling request signal, wherein each of said communication stations judges a transmission demand based on a state of a device connected to one of said plurality of communication stations or a state of a wire transmission line for connection to the device, and transmits the request signal.
