Abstract: Embodiments of this application provide a session management method, an interworking method between different systems, and a network apparatus. The session management method includes: when establishing a guaranteed bit rate (GBR) flow of a terminal device in a first communications system, determining, by a session management network element in the first communications system, that the GBR flow is a GBR flow required for handing over the terminal device from the first communications system to a second communications system; and establishing, by the session management network element for the GBR flow, a session context corresponding to the second communications system. The methods and the network apparatus are used to resolve a technical problem of resource waste existing in a handover method in the prior art.

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 sending, by a first data analytics network element, a first request to a service discovery network element. The first request requests information about a second data analytics network element. The first request includes one or more of information about distributed learning or first indication information. The information about distributed learning includes a type of distributed learning. The first indication information indicates a type of the second data analytics network element. The method also includes receiving, by the first data analytics network element, information about the second data analytics network element from the service discovery network element. The second data analytics network element supports the type of distributed learning.
