Question: What is the primary purpose of the UE Context Release Request procedure initiated by the eNB in an E-UTRAN network?
Option 1: To establish a new S1-connection for incoming UE traffic
Option 2: To release the UE-associated logical S1-connection due to E-UTRAN generated reasons
Option 3: To modify existing QoS settings for an active UE session
Option 4: To request location updates from the MME for a specific UE
Explanation: The correct answer reflects the procedure's main objective in E-UTRAN operations. Releasing the UE-associated logical S1-connection is crucial for managing resources efficiently, especially when triggered by E-UTRAN-specific reasons. This action ensures network optimization and proper resource allocation. The other options are incorrect because they do not align with the primary purpose of releasing connections rather than establishing, modifying, or requesting updates.
