Abstract: This application provides a message processing method and system, and a user plane function UPF device. The method includes: receiving user equipment (UE) authentication information sent by a session management function (SMF) device; matching a received uplink message of the UE with the UE authentication information, and if the matching succeeds, sending the uplink message that includes the UE authentication information to a first application (APP); and performing authentication by the first APP on the UE according to the UE authentication information. In the foregoing process, authentication on the UE does not need to be performed by a remote APP. This simplifies the authentication process, reduces network resource overhead, speeds up authentication on UEs, reduces the latency of UE authentication, and further increases the application switching speed.

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.
