Question: In a Dual Connectivity scenario, how is the UE Aggregate Maximum Bit Rate (UE AMBR) managed between the Master eNodeB (MeNB) and Secondary eNodeB (SeNB)?
Option 1: The entire UE AMBR is handled solely by the MeNB, with no allocation to the SeNB.
Option 2: The UE AMBR is split into two equal parts, one for MeNB and one for SeNB, without considering actual traffic distribution.
Option 3: The UE Aggregate Maximum Bit Rate is split into MeNB UE AMBR and SeNB UE AMBR, enforced by MeNB and SeNB respectively, as per specified protocols.
Option 4: The management of UE AMBR is transferred from the eNodeBs to the Mobility Management Entity (MME) in Dual Connectivity.
Explanation: In a Dual Connectivity setup, efficient resource allocation requires dividing the UE's Aggregate Maximum Bit Rate between the Master and Secondary eNodeBs. This division ensures both eNodeBs can enforce allocated bit rates for the UE, optimizing network resource utilization for Non-GBR bearers.
