Question: In a Dual Connectivity scenario with E-UTRAN as Master RAN node and NR as Secondary RAN node, how does the target eNodeB determine where to send the Configuration Transfer message?
Option 1: Based on the source address in the GTPv2 message.
Option 2: Based on the destination address in the GTPv2 message.
Option 3: Based on the MME's routing decision via the S10 interface.
Option 4: Based on the candidate en-gNB identified by the target eNodeB using the destination address.
Explanation: In a Dual Connectivity scenario with E-UTRAN as Master RAN node and NR as Secondary RAN node, the target eNodeB decides which candidate en-gNB to send the message to based on the destination address. This is because the destination address contains information about the intended recipient of the Configuration Transfer message, allowing the target eNodeB to route it correctly.
