Question: What is required for IoT devices connecting to a 5G network, even when accessing via non-3GPP access technologies (e.g., WLAN, fixed broadband access network), to ensure identification and management?
Option 1: A dynamic subscription with the 5G network, in addition to any existing subscriptions for non-3GPP access.
Option 2: Only a static provisioning of the IoT device's manufacturer details.
Option 3: Activation solely through the relay UE's subscription, without a direct subscription for the IoT device.
Option 4: No subscription is needed if the IoT device uses a non-3GPP access network.
Explanation: To manage and identify IoT devices securely and efficiently, especially with varying connectivity models (direct connection or via a relay UE) and potential changes in ownership or security credentials, a dynamic subscription method directly with the 5G network is necessary. This ensures flexibility and comprehensive management, even when non-3GPP access technologies are utilized for connectivity.
