Abstract: Embodiments of this application provide a media packet transmission method, an apparatus, and a system that relate to the field of communication technologies. In an example method, a transmit end network element obtains a correspondence between an encoding type and a quality of service (QoS) flow. The transmit end network element is a user plane network element or a terminal. The QoS flow is used to transmit a media packet whose encoding type is the encoding type corresponding to the QoS flow. The transmit end network element identifies an encoding type of a received media packet, and sends, based on the correspondence through a QoS flow corresponding to the encoding type of the media packet, the media packet carrying information associated with the encoding type to an access network element.

Abstract: According to a communication method and a communications apparatus, in a process in which an access network device serving a terminal is handed over from a source access network device to a target access network device, a user plane function network element may transmit first information to the source access network device. The first information is used to indicate that the user plane function network element bicasts downlink packets to the source access network device and the target access network device, so that after determining that a data packet received before the first information is sent to the terminal, the source access network device triggers an air interface handover, to avoid a packet loss in a handover process, or so that the source access network device synchronizes a PDCP SN of the source access network device with a PDCP SN of the target access network device.
