Message transmission method and apparatus
A terminal obtains network congestion control configuration information. The terminal processes a message generated by the terminal according to the network congestion control configuration information and obtains the processed message. Then the terminal sends the processed message. Therefore, the message generated by the terminal can be processed flexibly to relieve a network congestion problem in the Internet of vehicles.
