Abstract: A method and an apparatus for determining radio access policy include implementation by a first network element that obtains a movement manner of a terminal device. The first network element determines a radio access policy of the terminal device based on the movement manner of the terminal device. The radio access policy is used to indicate at least one of a radio access technology (RAT) selection priority of the terminal device, a frequency selection priority of the terminal device, or a cell selection priority of the terminal device enabling the terminal device to access a proper RAT system, frequency, or cell.

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 device and a method for implementing a data service in order to avoid generating an unnecessary data usage fee for user equipment (UE) and further avoid data usage waste after a data service switch of the UE is turned off. The method includes determining, by a first network-side device, a status of a data service switch of UE, and sending, by the first network-side device, a first notification message to a second network-side device when the data service switch of the UE is turned off, where the UE is already registered with a network, the first notification message includes first instruction information and an identity of the UE, and the first instruction information instructs the second network-side device to skip charging for data packets of the UE flowing through the second network-side device.
