摘要： This application discloses a communication method and a communications apparatus, and relates to the communications field. The communication method includes: obtaining, by a network data analytics function network element, an application information target value of a network slice in a specified location area; obtaining, by the network data analytics function network element, a network running information target value of the network slice in the specified location area based on an association relationship between application information and network running information and the application information target value, where the association relationship is used to describe an association relationship between application information and network running information when a communications service provided by the network slice in the specified location area meets a service level agreement SLA; and sending, by the network data analytics function network element, the network running information target value to an operation, administration, and maintenance server.

摘要： This application relates to the field of communication technologies, and provides a slice access method, apparatus, and system, to reduce a probability that a terminal service fails because a slice that is not suitable for a current to-be-initiated service is matched. The slice access method includes: receiving one or more user route selection policy rules URSP rules from a network apparatus, and performing URSP matching according to the one or more URSP rules. At least one URSP rule in the URSP rules includes indication information, and the indication information indicates to match one or more preset URSP rules or match one or more preset route selection descriptors RSDs. The method is applied to a network slice access procedure.

摘要： One example method includes receiving, by a network slice selection function network element, a first message from a mobility management network element, where the first message includes network slice selection assistance information (NSSAI) subscribed to by a terminal and slice subscription information of n third-party service providers (SPs) corresponding to the NSSAI subscribed to by the terminal, and slice subscription information of a third-party SP comprises a first identifier. The network slice selection function network element can obtain, based on the first identifier, first mapping information corresponding to each third-party SP. The network slice selection function network element can determine allowed NSSAI for the terminal based on the NSSAI subscribed to by the terminal and the first mapping information, where the allowed NSSAI is used to indicate one or more network slices that the terminal is allowed to access in a visited network of the terminal.

摘要： Embodiments of this application provide a method for controlling use of a network slice, an apparatus, and a system. The method includes: A first network element receives a first message used to request access of a terminal device to a target network slice. The target network slice covers a plurality of regions including a first region, and the first region is a region in which the terminal device is currently located. Further, the first network element determines, based on a first condition, whether to allow the terminal device to access the target network slice. The first condition includes: whether a service usage of the target network slice in the first region exceeds a first service limit.
