Question: In an Evolved Universal Terrestrial Radio Access Network (E-UTRAN), what is the primary purpose of the eNB Early Status Transfer Transparent Container Information Element (IE) during handover processes?
Option 1: To encrypt sensitive user data transmitted between the source and target eNB.
Option 2: To facilitate intra SAE/LTE S1 DAPS handover and S1 handover with time-based trigger condition, remaining transparent to the Evolved Packet Core (EPC).
Option 3: To manage Quality of Service (QoS) parameters for voice calls during inter-RAT handovers.
Option 4: To authenticate User Equipment (UE) identity across different eNBs.
Explanation: The correct answer highlights the IE's role in specific handover scenarios while emphasizing its transparency to the EPC, demonstrating an understanding of the IE's functional scope within E-UTRAN handover processes.
