Question: What action does an eNodeB (eNB) take when receiving an E-RAB RELEASE COMMAND message with duplicate E-RAB ID IEs for the same value?
Option 1: The eNB releases all corresponding E-RABs and sends a warning to the MME.
Option 2: The eNB initiates the release of one corresponding E-RAB and ignores the duplication.
Option 3: The eNB rejects the entire E-RAB RELEASE COMMAND message due to duplication error.
Option 4: The eNB requests clarification from the MME before taking any action.
Explanation: This is in line with standard protocols for handling duplicate instructions in signaling messages, ensuring efficiency and preventing unnecessary resource utilization. By releasing one instance of the duplicated E-RAB ID and ignoring the rest, the eNB maintains operational integrity while adhering to principles for handling abnormal conditions, minimizing potential network disruptions.
