Abstract: The present application relates to the technical field of communications, and provides a time synchronization method, an electronic device and a storage medium. A terminal sends a target protocol data unit (PDU) session establishment request to a session management function (SMF) according to a routing policy, wherein the target PDU session establishment request includes a target virtual private link identifier; and the terminal establishes a target PDU session with a target user plane function (UPF). The described method is applied to embodiments of the present application, so that a time synchronization message may be transmitted by means of the target PDU session and an interface indicated by target virtual private link information.

Abstract: Provided are a network slicing method and device, and a storage medium. The method includes: a terminal sending a target protocol data unit (PDU) session establishment request to a local SMF, wherein the PDU session establishment request includes terminal identification information, the PDU session establishment request is forwarded by the local SMF to a local UDM to request a user subscription, the local UDM acquires, according to the terminal identification information, target network slice information corresponding to the terminal identification information and notifies the local SMF, then the local SMF replaces initial network slice information with the target network slice information and determines to establish a PDU session; and the terminal receiving a bearer establishment notification sent by a base station according to an instruction of a local AMF for establishing a radio bearer, wherein the bearer establishment notification is used for instructing the terminal to establish a radio bearer.
