Data transmission optimization method, terminal, and network device

A terminal, comprising a processor, a memory, and a transmitter, wherein the memory is configured to store an instruction, and the processor is configured to:

• invoke the instruction stored in the memory to perform the following function of the processor, and control the transmitter to perform the following function:
• the processor is configured to determine that the terminal is to move along a track route comprised in a track context and reach a to-be-optimized route segment on the track route, wherein the track context is pre-generated by the terminal, and comprises 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, and the measurement parameter comprises at least one of signal quality, an uplink throughput rate, or a downlink throughput rate;
• and
• the transmitter is configured to send a data transmission optimization instruction to a network device when the processor determines that the terminal is to move along the track route comprised in the track context and reach the to-be-optimized route segment on the track route, wherein 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 comprises adjusting a resource allocation policy of the terminal.
