Abstract: This application discloses a network slice selection method and apparatus, to resolve a prior-art problem of large transmission load on a network side. The method performed by a core network device includes: receiving a first request message sent by a terminal device, where the first request message is used to request to allocate, to the terminal device, a network slice that provides a business service; sending a query message to a SSF, where the query message carries user information of the terminal device, and is used to query for a network slice that is capable of providing a business service for the terminal device; and after receiving slice information of the network slice that is capable of providing the business service required by the terminal device and that is determined based on the user information, forwarding the first request message to the network slice corresponding to the slice information.
