A method for a user equipment (UE) connected to a serving Radio Access Network (RAN) through a serving cell is provided. The serving RAN may include a Non-Terrestrial Network (NTN). The method receives, from the serving cell, satellite information regarding a coverage area of the serving RAN.

The method maintains an Access Stratum (AS) layer configuration of the UE without performing any task associated with an Idle mode of the UE while the UE is staying out of the coverage area of the serving RAN.
