Question: What is the primary purpose of the SeNB Counter Check procedure initiated by the Secondary Node B (SeNB) towards the Master eNodeB (MeNB) in an E-UTRAN architecture?
Option 1: To synchronize the MME (Mobility Management Entity) with updated UE location information.
Option 2: To request additional radio resources for SCG (Secondary Cell Group) bearers from the MeNB.
Option 3: To verify the accuracy of PDCP (Packet Data Convergence Protocol) COUNT values for SCG bearers established in the SeNB.
Option 4: To trigger a handover of UE from SeNB to another cell due to poor signal quality.
Explanation: The correct answer reflects the primary purpose of the SeNB Counter Check procedure. This procedure ensures data integrity and prevents potential errors or misalignments in PDCP COUNT values, vital for proper data transmission over established SCG bearers in the Secondary Node B (SeNB).
