Question: In E-UTRAN, what is the primary purpose of the Data Forwarding Address Indication procedure during a handover or Dual Connectivity scenario?
Option 1: To notify the User Equipment (UE) about changes in the Radio Resource Control (RRC) connection.
Option 2: To synchronize the clocks between the new and old eNodeBs (eNBs) for seamless handover.
Option 3: To provide data forwarding addresses from the new eNB to the old eNB, or between Master Node B (MeNB) and Secondary Node B (SeNB)/Next Generation Node B (en-gNB), facilitating data forwarding during handovers or Dual Connectivity.
Option 4: To initiate a Conditional Handover based on UE mobility patterns.
Explanation: The correct answer highlights the procedure's main goal: enabling the new eNB (or MeNB in Dual Connectivity scenarios) to share data forwarding addresses with the old eNB (or SeNB/en-gNB), ensuring uninterrupted data transfer during handovers or when employing Dual Connectivity, crucial for maintaining service continuity and performance in E-UTRAN networks.
