1. A video data transmission method, wherein the video data transmission method comprises:
receiving, by a network device, a plurality of data packets corresponding to a plurality of video frames from a server, wherein each of the plurality of video frames comprises one or more data packets;
determining, by the network device, a transmission phase of the one or more data packets corresponding to each video frame in the plurality of video frames, wherein the transmission phase comprises a frame header, a frame middle, or a frame tail;
determining, by the network device based on the transmission phase of the one or more data packets corresponding to each video frame, a priority of the one or more data packets corresponding to each video frame;
sending, by the network device based on the priority of the one or more data packets corresponding to each video frame, the one or more data packets corresponding to each video frame to a terminal device corresponding to each video frame; and
sending, by the network device, handover instructions to a terminal device after the network device completes transmitting one or more data packets in a frame tail in a video frame corresponding to the terminal device.
