Abstract: A terminal device determines a target network slice group; determines at least one candidate cell based on the target network slice group, where a frequency corresponding to the candidate cell supports the target network slice group; and selects a to-be-camped-on cell based on the at least one candidate cell. The method further includes: The terminal device receives system information from an access network device of a serving cell. The system information includes a network slice group supported by a frequency corresponding to the serving cell and/or a priority of the network slice group supported by the frequency corresponding to the serving cell; or the system information includes a network slice group supported by a frequency corresponding to a neighboring cell and/or a priority of the network slice group, and indication information indicating whether the serving cell supports the network slice group supported by the frequency corresponding to the neighboring cell.

Abstract: A radio access network RAN device receives a first message, where the first message includes identifiers of one or more first network slices, and the identifiers of the one or more first network slices are the same as identifiers that are of the one or more first network slices and that are included in a non-access stratum NAS request message sent by a terminal device to a core network CN device by using the RAN device; and the RAN device sends a second message including network slice redirection information to the terminal device, where the network slice redirection information includes at least one of network slice remapping information and terminal device redirection information, and the network slice redirection information is obtained after the RAN device performs network slice redirection decision-making on the one or more first network slices.

Abstract: This application provides example data transmission control methods and example apparatuses. One example method includes receiving, by a terminal device, first information from a network device, where the first information indicates an uplink maximum bit rate of each of at least one logical channel. The terminal device can then allocate an uplink resource to one or more logical channels in the at least one logical channel based on the uplink maximum bit rate.

Abstract: This application discloses a handover method and apparatus. During handover, a source RAN node includes, in a handover message, an indication indicating whether a PDU session supports network slice re-mapping and/or an indication indicating whether the PDU session supports network slice fallback. A target RAN node performs admission control based on the indication, and notifies the source RAN node of an identifier of a network slice to which the PDU session is re-mapped or an indication indicating whether the PDU session falls back to a default network slice. The source RAN node forwards the notification to a terminal device. This reduces signaling overheads caused during handover interaction.

Abstract: The technology of this application relates to a cell reselection method and a communication apparatus, among other aspects. In certain example embodiments, a terminal device determines priority information of a target network slice group, where the priority information indicates a priority of the target network slice group, and the terminal device performs cell reselection based on a cell frequency that is associated with the target network slice group and determined based on the priority information. In some implementations, the target network slice group includes a network slice that the terminal device expects to access or a default network slice.

Abstract: A relay terminal device receives a request message from a remote terminal device. The relay terminal device performs access control based on first slice information and second slice information. The relay terminal device sends a response message to the remote terminal device, where the request message is used to request to communicate with an access network device through the relay terminal device, the request message includes the first slice information, the first slice information includes information about a slice that the remote terminal device intends to access, and the second slice information includes information about a slice supported by a cell on which the relay terminal device currently camps or a cell that currently serves the relay terminal device.

Abstract: This application provides a handover control method, an admission control method, and a communication apparatus. A first access network device obtains mapping information between an access network slice instance of a second access network device and a network slice; the first access network device determines, based on the mapping information, that the second access network device supports a first network slice associated with a service currently performed by a terminal device; and the first access network device sends first request information to the second access network device, where the first request information is used to request to enable the terminal device to access the second access network device, and then the second access network device performs admission control. In this technical solution, continuity of a network slice service can be ensured when the terminal device performs handover between access network devices, and impact on a core network can be reduced.
