Question: What is the primary purpose of the Radio Link Failure Indication procedure in E-UTRAN?
Option 1: To establish a new radio link for a UE experiencing connection failure directly with the target eNB.
Option 2: To optimize handover procedures between eNBs based on UE signal strength.
Option 3: To synchronize RRC states across all eNBs in a given network area.
Option 4: To share information about RRC re-establishment attempts or received RLF Reports between eNBs to aid in detecting radio link and handover failures.
Explanation: The Radio Link Failure Indication procedure facilitates the exchange of information (regarding RRC re-establishment attempts or received RLF Reports) between eNBs, helping identify cases of radio link failure and handover failure for network optimization and seamless UE connectivity. The other options misrepresent the procedure's primary goal.
