Abstract: The disclosure provides communication methods and apparatuses. One example method includes receiving, by a first network device, a first message from a second network device, where the first message includes network slice configuration information. The network slice configuration information is used to indicate a maximum data rate provided by each of n network slices for a terminal device, and n is an integer greater than or equal to 1. In response to the received first message, the first network device sends a second message to the second network device.

Abstract: This application provides a communication method and apparatus, which may be used for random access optimization. In this method, a CU may send, to a DU, obtained PRACH configuration information of a plurality of cells. The DU receives the PRACH configuration information of the plurality of cells from the CU, and performs random access optimization based on the PRACH configuration information of the plurality of cells. In an existing technology, a base station may adjust RACH configuration information of the base station based on PRACH configuration information of a neighboring base station, to perform random access optimization.

Abstract: Examples in this application provide a communication method and a communications apparatus. One example communication method includes determining to deactivate or activate a first synchronization signal and physical broadcast channel block (SSB), and sending a first request message to a second network device. Specifically, the first request message carries first indication information for indicating the first SSB, and when the first SSB is an SSB in the first network device, the first request message requests the second network device to update a state of the first SSB, and the second network device maintains information about at least one SSB in the first network device, or when an active first SSB is an SSB in the second network device, the first request message requests the second network device to activate the first SSB, and the first network device maintains information about at least one SSB in the second network device.

Abstract: Embodiments of this application disclose a communication method, a terminal device, and a core network device. The method includes: The terminal device sends, through a radio access network device, a registration request message including first network slice information to the core network device. The first network slice information is information about a first network slice corresponding to a PDU session that the terminal device expects to establish. The terminal device receives, through the radio access network device, a registration accept message that is sent by the core network device and that includes information about a first registration area allocated to the terminal device and second network slice information, the second network slice information is information about a second network slice that is allowed to be used by the terminal device in the first registration area, and the second network slice information includes the first network slice information.

Abstract: The present disclosure discloses example wireless network communication methods and network devices. One example method includes sending a first message to a second network device by a first network device, where the first message includes measurement object information of the first network device. A second message sent by the second network device is received by the first network device, where the second message includes indication information or measurement result information of the first network device, and the indication information indicates whether an inter-system unnecessary handover of a terminal device occurs. The first network device determines, based on the second message, whether the inter-system unnecessary handover of the terminal device occurs.

Abstract: Example grouping methods, apparatuses, and systems are provided. One example method includes receiving, by a central unit, a first interference intensity indication reported by at least one distributed unit. The central unit can then group the at least one distributed unit into at least one first distributed unit group based on the first interference intensity indication. The central unit can then send, to a controller, a distributed unit grouping indication and a second interference intensity indication that corresponds to the at least one first distributed unit group, where the distributed unit grouping indication is used to indicate the at least one first distributed unit group.

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.
