PROBLEM TO BE SOLVED: To provide a polling control system that can increase the band of an outgoing signal from a station to a terminal device. SOLUTION: In the polling control system where a station 101 transmits polling information to a terminal device 10 with a transmission signal, when the polling information sent to the terminal device 10 has no change, no polling information is transmitted and only when the polling information has a change, the polling information is transmitted. When the terminal device 10 receives no polling information, the terminal device 10 reads repetitively the polling information sent just before and uses it. Since a main signal is inserted to a signal part corresponding to the polling information when the polling information is not sent, a band (information quantity) of the outgoing signal from the station 101 to the terminal device 10 can be increased.
