Question: What determines the point in time when the feeder link switch over between two gNBs is performed?
Option 1: The NTN Control function
Option 2: The UE's context transfer protocol
Option 3: The gNBs' implementation and configuration information
Option 4: The NG-RAN architecture
Explanation: The NTN Control function is responsible for determining the point in time when the feeder link switch over between two gNBs is performed, as it has the necessary information to make this decision. This highlights the importance of the NTN Control function in managing the feeder link switch over process and ensuring seamless communication between gNBs.
