Section: 4.23.4 5GS session management via a satellite NG-RAN cell
Content: For 5GS session management via a satellite NG-RAN cell the UE shall apply the value of the applicable NAS timer indicated in table 10.2.1 for access via a satellite NG-RAN cell. NOTE 1: The applied NAS timer values are based on the current satellite NG-RAN access RAT type determined based on information from lower layers. The NAS timer value obtained is used as described in the appropriate procedure subclause of this specification. The NAS timer value shall be calculated at start of a NAS procedure, and shall not be re-calculated until the NAS procedure is completed, restarted or aborted. If the use of extended NAS timer for access via a satellite NG-RAN cell is indicated by the AMF (see 3GPP TS 23.501[ System architecture for the 5G System (5GS) ]  [8] and 3GPP TS 23.502[ Procedures for the 5G System (5GS) ]  [9]), the SMF shall calculate the value of the applicable NAS timer indicated in table 10.3.2 for access via a satellite NG-RAN cell. The NAS timer value obtained is used as described in the appropriate procedure subclause of this specification. The NAS timer value shall be calculated at start of a NAS procedure and shall not be re-calculated until the NAS procedure is completed, restarted or aborted.
