Abstract: Embodiments of the present application provide a data transmission method and a communications apparatus. A Hypertext Transfer Protocol version 2 HTTP/2 adaptation layer is configured between an application layer and a Multipath Transmission Control Protocol MPTCP layer of a protocol stack. All frames belonging to a same HTTP/2 stream are allocated to a same MPTCP subflow for transmission, so that a data throughput is large, and system robustness is good, thereby improving HTTP/2 stream transmission performance.

Abstract: The present disclosure relates to media unit transmission methods and apparatuses. In one example method, a user plane network element receives a media unit, where the media unit includes a plurality of data packets. The user plane network element sets marking information for the media unit, where the marking information is for determining that the media unit is a media unit allowed to be discarded. The user plane network element sends the media unit that carries the marking information.

Abstract: Embodiments of the present disclosure provide a method. According to the method, a mark is added to a data packet. After user equipment is handed over from an original device to a target device, and before a user plane network element receives a handover notification, the user plane network element sends, through a path used before handover, a data packet that carries a first mark to the original device. The original device modifies the first mark in the data packet to a second mark, and then forwards, to the target device, a data packet whose mark is modified and that carries the second mark. After receiving the handover notification, the user plane network element sends, to the target device, a data packet that carries a fourth mark. The target device can distinguish between sources of the received data packets based on different marks in the received data packets.
