Abstract: The present disclosure relates to network management methods. One example method includes obtaining, by a network slice selection function (NSSF), a configuration parameter sent by a network slice management and orchestration module (NSMAO), where the configuration parameter includes a correspondence, the correspondence includes at least one of a correspondence between single network slice selection assistance information (S-NSSAI) and a network slice instance identifier (NSI ID) or a correspondence between the S-NSSAI and a network slice subnet instance identifier (NSSI ID), and the configuration parameter instructs the NSSF to select, based on the configuration parameter, at least one of a network slice instance (NSI) or a network slice subnet instance (NSSI) for S-NSSAI provided by user equipment.

Abstract: A method for providing service is provided. A network slice management system of an operator receives a service request message sent by a control device of a third-party service provider. The service request message is used to request the network slice management system to provide a service, and the service request message carries a service requirement. The network slice management system creates a network slice instance based on the service requirement. The network slice instance is used to provide the requested service. The network slice management system sends a notification message to the control device. The notification message carries an identity of the network slice instance.

Abstract: This application provides an information transmission method when a terminal device accesses a serving radio access network (RAN) device. The terminal device receives an identifier of a first cluster-data function (C-DF) associated with the serving RAN device from the serving RAN device, where the first C-DF is located in a radio access network and stores current data of the terminal device. When the terminal device camps on the serving RAN device longer than or equal to a first threshold, the terminal device stores the identifier of the first C-DF.

Abstract: The present invention discloses a wireless network access control method and an apparatus. The method includes: configuring, by a wireless network, an independent access control parameter for each network slice, so as to implement differential access control, by the network, on access to different network slices that is initiated by a terminal device. In addition, a core network or a radio access network initiates network slice overload control or a network slice access control parameter adjustment based on resource usage of each network slice in the network. By separately controlling and adjusting the access control parameter of each network slice, it is ensured that impact between network slices is minimized.
