The terminal determines to move along a track route included in a track context and reach a to-be-optimized route segment on the track route, where the track context is pre-generated by the terminal, and includes a track route along which the terminal moves and that is passed through by the terminal in a historical time and a to-be-optimized route segment on the track route, a value of a predefined measurement parameter meets a preset threshold value range when the terminal moves in the to-be-optimized route segment. The terminal sends a data transmission optimization instruction to a network device, where the data transmission optimization instruction is used to instruct the network device to perform a data transmission optimization processing operation, and the data transmission optimization processing operation includes adjusting a resource allocation policy of the terminal.
