Abstract: Embodiments of the present invention provide a method, an apparatus, and a system for creating a network slice. The method includes: receiving, by a network slice control function (NSCF) entity, a service deployment command sent by a network slice management function NSMF entity; obtaining, by the NSCF entity, a service-related requirement parameter, a model, a policy, and a plan of a network slice, and registration information of a network function entity based on the service deployment command; generating, by the NSCF entity, a service configuration scheme of the network function entity based on the model and the policy of the network slice and one or more of the service-related requirement parameter, the registration information of the network function entity, and the plan of the network slice; and sending, by the NSCF entity, the service configuration scheme to the network function entity. Therefore, a network slice can be automatically created.

Abstract: This application discloses a communication method and apparatus. A first AMF device receives a first request message, where the first request message includes an identifier of a first network slice that a terminal requests to access and an identifier of a tracking area in which the terminal is located. When the first AMF device determines that the tracking area supports the first network slice, the first AMF device sends a response message, where the response message includes a first radio access selection priority index corresponding to the first network slice. The first radio access selection priority index is for selection of an access network device that supports the first network slice at the terminal. Even if an access network device currently accessed by the terminal does not support the first network slice, the terminal may re-access the access network device that supports the first network slice.

Abstract: Embodiments of the present application provide a slice instance management method and apparatus. The method includes: receiving, by a slice instance management node, a first service request from an operator system, where the first service request includes information about a management operation to be performed by the operator system on a first network element, and the first network element is a network element in a slice instance managed by the slice instance management node; and if the first service request is within first management rights, sending the information about the management operation to be performed by the operator system on the first network element to the first network element, where the first management rights are management rights of the operator system for the slice instance that are included in a description file of the instance management node.

Abstract: Embodiments of this application disclose a data obtaining method and system, and an apparatus thereof. The method includes: A network data analytics network element determines a data source to which to-be-obtained data belongs; determines, based on first information, an object identifier that is of the data source and that is in an operation, administration, and maintenance OAM system; and sends a first request to the OAM system. The first request includes the object identifier, and the first request is for requesting to obtain the to-be-obtained data. In this manner, a process in which the network data analytics network element obtains data of a managed object from the OAM system can be simplified.

Abstract: A slice control method and apparatus are provided. The method includes: a policy control network element receives, from a slice access control network element, slice access status information of a network slice, the slice access status information comprises information indicating a network slice traffic bandwidth of the network slice; determines, based on the current slice access status information of the network slice, that the network slice traffic bandwidth exceeds a corresponding maximum value allowed by configuration; generates, in response to the determination, first session policy control information for a first session in the network slice; and sends the first session policy control information to a session management network element corresponding to the first session, the first session policy control information being for policy control on the first session.

Abstract: 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.

Abstract: 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.
