Question: What happens to the configuration data not included in the MME CONFIGURATION UPDATE message during the MME Configuration Update procedure?
Option 1: The eNB deletes the unused configuration data to free up storage.
Option 2: The eNB requests clarification from the MME for the missing configuration data.
Option 3: The eNB interprets the not-included configuration data as still valid and continues using it.
Option 4: The eNB initiates a failure response due to incomplete configuration update.
Explanation: This is because, according to the procedure, if certain configuration data are not included in the MME CONFIGURATION UPDATE message, the eNB (eNodeB) assumes those configurations remain unchanged and thus, continues to use them. This ensures continuity of service with the last known valid settings for any parameters not updated.
