The invention discloses a satellite mobile communication system circuit domain measurement and control data transmission method, and relates to the technical field of communication. The method comprises the following steps: a transmitting end Tiantong terminal and a receiving end Tiantong terminal enter a call mode, and a voice channel is changed into a data state; the external device sends to-be-sent measurement and control data to the sending end Tiantong terminal through a serial port, and the sending end Tiantong terminal accesses the data in a queue by controlling semaphore and sends the data to an air interface; and the Tiantong terminal of the receiving end receives the data sent by the sending end in a call mode, detects the data, sends the measurement and control data to external equipment of the receiving end for processing if receiving the measurement and control data, and discards the measurement and control data if not. Measurement and control data transmission is carried out based on the circuit
