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.

Abstract: Embodiments disclose a communication method. The method includes: A first network element obtains a first authentication status of a target network slice of a first terminal device from a data management function network element, where the first authentication status indicates a first authentication result of the target network slice, or the first authentication status indicates that no authentication procedure has been performed on the target network slice. The first network element determines, based on the first authentication status, whether to perform a first authentication procedure on the target network slice. The embodiments of this application further provide a corresponding network element.

Abstract: This application provides a method for allocating an IP address, including: establishing, by a session management network element, a session for a terminal apparatus, where the session is used for transmitting a data packet via a control plane network element; allocating, by the session management network element, an IP address to the terminal apparatus; and sending, by the session management network element, the data packet to the terminal apparatus via a mobility management network element, where the data packet includes the IP address. In a case in which the terminal apparatus can obtain the IP address without establishing an additional connection channel, the terminal apparatus can obtain the IP address more flexibly, and occupation of excessive signaling resources can be avoided.
