Abstract: Embodiments of this application provide a roaming method. The method includes: A terminal device accesses a second PLMN when the terminal device cannot access a first PLMN, where a dynamic roaming agreement between the second PLMN and the first PLMN is enabled; the terminal device receives indication information from the second PLMN, where the indication information is used to indicate to disable the dynamic roaming agreement between the second PLMN and the first PLMN; and the terminal device sends an access request message to the first PLMN based on the indication information.

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.

Abstract: This application provides a core network control plane device selection method and apparatus. The method includes: obtaining, by a source core network control plane device, first network slice selection assistance information of a terminal device; and if the source core network control plane device cannot determine a target core network control plane device indexed by the first network slice selection assistance information, sending, by the source core network control plane device, the first network slice selection assistance information and first indication information to the terminal device, to trigger the terminal device to send a first registration request message. The first indication information indicates that a temporary identifier of the terminal device is invalid, and the first registration request message carries the first network slice selection assistance information and a permanent identifier of the terminal device.
