TIME SYNCHRONIZATION METHOD, ELECTRONIC DEVICE AND STORAGE MEDIUM

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 comprises 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, so as to achieve time synchronization between a first clock node to be synchronized connected to a first interface and a second clock node to be synchronized connected to a second interface without the need for a communication system to support a time synchronization protocol. The method has simple implementation characteristics, which is advantageous to the rapid deployment and application of time-sensitive networks.
