Abstract: A resource scheduling method for a network slice is provided, where a slice management network element sends a request to a data analysis network element. The request includes service experience requirement information of a first network slice. The slice management network element receives a response sent by the data analysis network element. The response includes information about a first area and/or information about a first time that are/is of the first network slice and that correspond/corresponds to the service experience requirement information. The slice management network element sends information about a second area and/or information about a second time to a network device based on the information about the first area and/or the information about the first time. The network device schedules a resource for the first network slice based on the information about the second area and/or the information about the second time.

Abstract: A communication method includes receiving, by a second data analytics network element, a status analytics output of a target object from a first data analytics network element. The target object includes one or more of a network device, a sub-domain of a network, an all-domain of a network, or a terminal device. The communication method also includes obtaining, by the second data analytics network element based on the status analytics output of the target object, first input data corresponding to a target type of analytics. The status analytics output of the target object indicates that the target object is in an abnormal state, indicating that the first input data does not comprise data corresponding to the target object. The communication method further includes generating, by the second data analytics network element based on the first input data, a first analytics output corresponding to the target type of analytics.

Abstract: Embodiments of the present disclosure disclose a circuit switched fallback method, a network device, and a system. The method includes: determining, by the network device, that a serving cell handover process of UE is ended; determining, by the network device, that before the serving cell handover process of the UE is ended, it has been determined that the UE needs to be moved to a second network supporting a circuit switched service; and moving, by the network device, the UE to the second network. According to the foregoing method, when CSFB triggered by a CS service initiated by UE conflicts with a serving cell handover process of the UE, the CS service of the UE can continue to be performed after completing the serving cell handover process of the UE. In this way, a success rate of establishing the CS service is increased.
