Question: What is the primary purpose of the Source To Target Transparent Container Information Element (IE) in the context of E-UTRAN handovers?
Option 1: To encrypt sensitive user data during handover procedures between different RAN nodes.
Option 2: To manage resource allocation for incoming UE connections at the target RAN node.
Option 3: To transparently pass radio-related information from the handover source to the handover target through the Evolved Packet Core (EPC).
Option 4: To initiate a handover failure alarm if the target RAN node is overloaded.
Explanation: The correct answer highlights the key function of the Source To Target Transparent Container IE, facilitating seamless transfer of radio-related information between source and target RAN nodes during handover via the EPC, ensuring service continuity for User Equipment (UE) by maintaining crucial context.
