Communication System

Abstract: A communication system is disclosed in which a user equipment (UE) communicates via a Non-Terrestrial Network (NTN) comprising a plurality of cells. The UE receives, from a base station/NTN gateway, information related to switching a communication connection from a first cell to a second cell of the NTN. Based on the received information, the UE suspends the communication connection in the first cell but maintains a Radio Resource Control (RRC) configuration associated with that cell. The UE switches to the second cell based on the received information and monitors for a trigger for performing a random access procedure via the second cell for synchronisation. When the UE receives a trigger, it performs the random access procedure via the second cell and resumes the communication connection in the second cell using the RRC configuration associated with the first cell.
