摘要： A method and a device for handover in an EFB-based non-terrestrial network are provided. The method may be performed in a first cell of a first satellite. The method includes performing a connection configuration procedure with a UE. The method also includes, after performing the connection configuration procedure, decreasing a value of a cell service timer, that indicates the time at which a communication service can be provided in the first cell, according to a decrement interval. The method additionally includes, in response to determining that the cell service timer is below a threshold, triggering a handover procedure.
