1. A network slice redirection method, comprising:
receiving, by a radio access network (RAN) device, a first message, wherein the first message comprises 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 comprised in a first non-access stratum (NAS) request message sent by a terminal device to a core network (CN) device by using the RAN device; and
sending, by the RAN device, a second message to the terminal device, wherein the second message comprises network slice redirection information, the network slice redirection information comprises at least one of network slice remapping information or terminal device redirection information, 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, and the first NAS request message is received by the RAN device prior to the sending of the second message comprising the network slice redirection information.
