Abstract

Embodiments of this application disclose a relay transmission method and system, and a related device. The method includes: determining, by a relay terminal, a vehicle existing between a vehicle terminal i and a vehicle terminal j based on vehicle location information in received broadcast messages sent by N vehicle terminals; and when it is obtained through calculation that link quality of a communication link Rused when the vehicle terminal i and the vehicle terminal j communicate with each other is lower than a preset threshold, forwarding, to the vehicle terminal j, a broadcast message sent by the vehicle terminal i, and forwarding, to the vehicle terminal i, a broadcast message sent by the vehicle terminal j. A relay forwarding function of the relay terminal avoids communication interruption or communication distance limitation caused by blocking due to dynamic and unpredictable factors such as a large vehicle within the Internet of vehicles, thereby improving reliability of message transmission within the Internet of vehicles.
