Abstract: Various embodiments provide a packet transmission method and an apparatus. In those embodiments, a first device supports a first protocol layer, and replicates a packet at the first protocol layer. A second device supports a second protocol layer, and deduplicates the packet at the second protocol layer. When receiving a first packet, a first access device converts a sequence number of the first protocol layer in the first packet into a sequence number of the second protocol layer, and then sends, to the second device, a second packet that carries the sequence number of the second protocol layer and a data packet of the first packet. For example, if the first access network device receives two packets having same data packets, the first access network device separately coverts sequence numbers in the two packets without performing operations of first deduplicating and then replicating the packet.

Abstract: This application provides example network slicing-based communication methods and apparatuses. One example method includes receiving, by a radio access network device, a registration request from user equipment, where the registration request includes first information and second information, where the first information is used to indicate a type of a first network slice, and where the second information is used to identify a first network slice instance in the first network slice. The radio access network device can then determine an access and mobility management function network element based on the type of the first network slice and the first network slice instance. The radio access network device can then send the registration request to the access and mobility management function network element, where the first information and the second information are used for network slice instance determining.
