Question: What action does a UE (User Equipment) take regarding its non-3GPP connection when `n3c-IndirectPathAddChange` is set to "setup" for an N3C indirect path, indicating a new relay UE?
Option 1: The UE continues using the existing non-3GPP connection in parallel with the new relay UE.
Option 2: The UE considers the source non-3GPP connection as not to be used, effectively switching to utilize the connection via the newly indicated relay UE.
Option 3: The UE releases all non-3GPP connections and waits for further RRC (Radio Resource Control) configuration.
Option 4: The UE ignores the `n3c-RelayIdentification` and maintains its current connectivity setup.
Explanation: When `n3c-IndirectPathAddChange` is set to "setup" with a new relay UE indicated, the UE is instructed to consider the source non-3GPP connection as not to be used for the N3C indirect path. This implies a switch to utilizing the connection through the newly specified relay UE, ensuring efficient resource allocation and adherence to the updated RRC configuration for N3C (Non-3GPP Access to 5GC) indirect paths.
