摘要： This application provides a network node selection method and apparatus. An SMF network element obtains transmission capability information of an access network device, and selects, for a terminal device based on the transmission capability information of the access network device, a UPF network element that supports at least one transmission capability included in the transmission capability information. In this process, the SMF network element obtains a transmission capability of the access network device, and selects the UPF network element based on the transmission capability of the access network device. The selected UPF network element supports the transmission capability used by the access network device, so that data can be successfully transmitted between the access network device and the UPF network element. Therefore, a data transmission success rate is improved.

摘要： This application provides methods and communication apparatus for transmitting a data packet of a media stream. The method can include an access network element receiving M data packets of a media stream from a user plane network element. When a network resource of the access network element cannot satisfy a transmission requirement of a terminal device, the access network element drops N data packets with lower priorities in the M data packets, where N≤M. The access network element sends, to the terminal device, a data packet that is not dropped and sequence numbers that represent sending sequences of the data packets and that are carried in the N data packets, and receives, from the terminal device, an ACK feedback for the sequence numbers carried in the N data packets. In the solutions discussed herein, video playback experience on a user side can be substantially ensured.
