Question: What action can eNB1 take if it doesn't receive an acknowledgement or failure response after initiating an eNB Configuration Update procedure towards eNB2, given that the new update message's content remains unchanged from the previous unacknowledged one?
Option 1: Reinitiate the eNB Configuration Update procedure with the same content towards eNB2.
Option 2: Modify the update content and then reinitiate the eNB Configuration Update procedure towards eNB2.
Option 3: Abort the update process and notify MME (Mobility Management Entity) about the failure.
Option 4: Automatically escalate to a manual configuration update process for eNB2.
Explanation: According to standard practices in E-UTRAN for handling abnormal conditions, if an acknowledgement or failure message is not received after initiating a procedure like eNB Configuration Update, the originating node (eNB1) may reattempt the procedure under specific conditions. Since the new message's content is identical to the previous unacknowledged one, reinitiating with the same content is permissible, aligning with principles of retry mechanisms in telecommunications to ensure reliability before considering alternative actions.
