Question: What is the primary purpose of the procedure described in the context of Control Plane CIoT 5GS Optimization?
Option 1: To establish a new RRC connection between the UE and ng-eNB.
Option 2: To terminate an existing RRC connection between the UE and ng-eNB.
Option 3: To modify the AS security context stored in the UE and ng-eNB.
Option 4: To allow the ng-eNB to suspend an RRC connection for later resumption by the UE.
Explanation: The correct answer is Option 4 because the primary purpose of this procedure is to enable the ng-eNB to suspend an RRC connection, which can then be resumed by the UE at a later time. This allows for efficient management of resources and minimizes the need for repeated connection establishment procedures.
