Section: 6.16.1 Security handling in Control Plane CIoT 5GS Optimization 6.16.2.1 General
Content: The purpose of this procedure is to allow the ng-eNB to suspend an RRC connection to be resumed by the UE using User Plane CIoT 5GS Optimisation at a later time. The UE may resume the RRC connection in the same or different ng-eNB where the suspend took place. The UE and ng-eNB store the AS security context at suspend and reactivate the AS security context at resume. The UE and the ng-eNB may also use EDT (Early Data Transmission) or PUR (Preconfigured Uplink Resource) feature in this procedure, as defined in TS 36.300[ Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 ]  [88] and TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [69].
