Time synchronization method and apparatus, computer-readable medium, and electronic device

A time synchronization method, comprising:

• receiving a time sensitive network (TSN) activation request transmitted by a unified data management entity (UDM), the TSN activation request comprising a first information used for indicating a TSN time synchronization trigger condition;
• detecting whether a target user equipment (UE) is in a connection management idle state;
• initiating a network triggered service request procedure in response to detecting that the target UE is in the connection management idle state, so as to establish a signal connection to the target UE;
• and
• in response to detecting that the target UE is in a connection management connected state, transmitting a control signal to the target UE corresponding to a current access and mobility management function entity (AMF) based on the first information, so as to control the target UE to perform a TSN time synchronization operation.
