Abstract: A network slice selection policy updating method and an apparatus are disclosed. The method includes sending, by a terminal device, configured network selection assistance information on the terminal device to an AMF, where the network selection assistance information includes a first slice identifier. The method further includes receiving, by the terminal device, allowed network selection assistance information and indication information that are returned by the AMF, where the allowed network selection assistance information includes a second slice identifier, and the indication information indicates that the second slice identifier corresponds to the first slice identifier. This can prevent the terminal device from initiating an unnecessary session establishment procedure, and save network resources.

Abstract: This application provides a communication method and apparatus. The method includes: After receiving a first packet from a first device, a first user plane network element determines a user plane LAN identifier corresponding to the first packet, where the user plane LAN identifier is an identifier that is in a user plane and that is of a LAN group to which the terminal belongs, and one user plane LAN identifier corresponds to one LAN group. That is, a function of the user plane LAN identifier is to isolate user plane packets of different LAN groups. Then, the first user plane network element sends the first packet to a second device based on the user plane LAN identifier and a destination address included in the first packet, so that the first packet sent by one terminal in the LAN group is sent to another terminal in the LAN group.

Abstract: Embodiments of this application provide a network slice selection method. The method includes: A first network device obtains user characteristic information of a current user of a first terminal, where the user characteristic information includes one or more pieces of single network slice selection assistance information S-NSSAI corresponding to the current user. The first network device determines, based on the user characteristic information, allowed NSSAI corresponding to the first terminal, where the allowed NSSAI includes the one or more pieces of S-NSSAI; or when the first network device does not support serving a network slice indicated in the one or more pieces of S-NSSAI, the first network device determines, based on the one or more pieces of S-NSSAI, a second network device that supports serving the network slice indicated in the one or more pieces of S-NSSAI.

Abstract: In a communication method, when a terminal device initiates establishment of a session of an Ethernet type, a virtual local area network management function entity in a communications system may determine a virtual local area network identifier of a user group to which the terminal device belongs. In this way, a user plane function entity in the session of the terminal device may allocate a plurality of virtual ports to a virtual local area network whose identifier is the virtual local area network identifier and may broadcast the Ethernet broadcast frame on the plurality of virtual ports.
