Abstract
A Beidou short message communication method and a system for a low-power user terminal are provided. The method includes following steps: by a user terminal, receiving outbound signals broadcast by a central station and forwarded by a satellite transponder, and constructing a short message access frame with a fixed length for transmission; by the central station, receiving and parsing the short message access frame, so as to realize the allocation of time-frequency resource blocks and transmit the time-frequency resource blocks to the user terminal; by the user terminal, transmitting a short message communication frame with a fixed format to the central station; by a communication receiving device of the central station, receiving and sequentially carrying out sampling preprocessing, anti-interference processing, rapid capture and tracking demodulation on the short message communication frame to obtain communication service information, and pushing receipt information to the user terminal to complete an information push.
