    Abstract: A data buffering method including: a session management function (SMF) interacting with a first user plane function (UPF1) and a second UPF2, such that the UPF1 sends first downlink data of a first session to an access network device via UPF2, where UPF1 is an anchor of the first session; and the SMS releasing UPF2 in a procedure in which a terminal device enters an idle state and a transmission resource associated with the first session in an access network is released, where UPF1 buffers incoming second downlink data of the first session. After the terminal device is switched to a connected state, both a transmission path of incoming third downlink data of the first session and that of the buffered second downlink data pass through UPF1, UPF3, the access network device, and the terminal device successively.

    Abstract: A clock source determining method and an apparatus are provided. The method includes: A session management network element receives a session request from a mobility management network element. The session request includes information about a network slice and a DNN, and the session request is used to request to create a session. The session management network element determines clock source information corresponding to both the information about the network slice and the DNN. The session management network element sends the clock source information to an access network device. The clock source information is used by the access network device to perform clock synchronization with a terminal device.

    Abstract: This application discloses a network slice management method and a device that is designed to improve network slice deployment efficiency. In the network slice management method, after obtaining indication information of a network slice template and performance requirement information of a target network slice, a first network management device may determine deployment information of the target network slice based on the two pieces of information, and may manage the target network slice based on the deployment information of the target network slice, without manual involvement. Therefore, network slice deployment efficiency can be improved.
