Question: What are the primary objectives of the Connection Establishment Indication procedure in E-UTRAN?
Option 1: To manage UE mobility between different eNBs and trigger handover procedures.
Option 2: To establish a non-UE associated S1-connection for broadcasting system information.
Option 3: To complete the establishment of the UE-associated logical S1-connection and/or trigger reporting of UE Radio Capability by the eNB.
Option 4: To handle S1 interface congestion and prioritize signaling messages.
Explanation: The Connection Establishment Indication procedure is crucial for setting up a logical connection associated with a specific User Equipment (UE) on the S1 interface between the Evolved Node B (eNB) and the Mobility Management Entity (MME), and for the eNB to obtain and report the UE's radio capabilities, optimizing network resource allocation and service provisioning.
