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 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. 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 or 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.
