Abstract: This application relates to the field of communications technologies. This application discloses a method, an apparatus, a network device, and a system for releasing an IP (Internet protocol) address, to resolve a problem that a time at which the IP address is released is not precise. The method includes: determining, by the first network device, that a PDU session anchor needs to be relocated from a first user plane function entity, where the first user plane function entity is the PDU session anchor of a first PDU session of a terminal; determining, by the first network device, that a first IP address of the terminal is no longer used, where the first IP address is an IP address used by the terminal in the first PDU session; and releasing, by the first network device, the first IP address.

Abstract: This application is directed to a method and an apparatus for associating an application with a network slice, and a communications system. The method includes: obtaining, by a terminal, display instruction information, an identifier of a first network slice that the terminal is allowed to access, and service feature information corresponding to the first network slice. The method further includes: displaying the service feature information corresponding to the first network slice on a first display interface of the terminal based on the display instruction information, and generating a first network slice selection policy when detecting an operation of associating a first application with the first display interface. The first network slice selection policy can include a mapping relationship between the first application and the identifier of the first network slice corresponding to the first display interface.

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.
