Question: What is the primary purpose of the ShortI-RNTI Information Element in E-UTRA Radio Resource Control (RRC) protocol?
Option 1: To authenticate User Equipment (UE) during initial access to the network.
Option 2: To manage Quality of Service (QoS) for multiple UEs in a cell.
Option 3: To identify a suspended UE context in RRC_INACTIVE state using a condensed identifier.
Option 4: To encrypt signaling messages between the UE and the base station.
Explanation: The ShortI-RNTI is used to identify a suspended User Equipment (UE) context when the UE is in the RRC_INACTIVE state, utilizing a condensed identifier. This enables efficient resource management and quick recovery of the UE's context when needed.
