Abstract: A communication method includes receiving, by a first communication apparatus, indication information from a second communication apparatus, and determining, by the first communication apparatus, a first quality of service (QoS) of the extended reality (XR) service based on the at least one piece of QoS of an XR service. The first communication apparatus is a core network device or an access network device. The indication information is useable to indicate at least one piece of QoS of the XR service. The XR device receives data of the XR service or sends data of the XR service by a terminal device. The second communication apparatus is an XR server or a chip in the XR server.

Abstract: This disclosure relates to the technical field, and discloses a network access method, a terminal, an access network, and a core network. The terminal obtains, based on the network service identifier, the network slice type identifier corresponding to a service identifier, and then accesses the network slice based on the access mode corresponding to the network slice type, thereby avoiding unavailability of the service caused by a failure to correctly access the network slice and improving service quality.

Abstract: The present application discloses an access method, apparatus, device, and system, and belongs to the field of communications technologies. The method includes: receiving, by a selection function entity SFE, an access request of user equipment UE sent by a radio access network node RAN node; determining a usage type of the UE based on the access request of the UE; and selecting, for the UE based on the usage type of the UE, a node that is in a dedicated core network and that can serve the UE, where the node that is in the dedicated core network and that can serve the UE corresponds to the usage type of the UE. Therefore, a node accessed by the UE is the node in the dedicated core network corresponding to the UE, and this ensures that the node can complete security verification of the UE.
