Question: In a 5G network, when Non-seamless WLAN Offload (NSWO) is supported by the Mobile Equipment (ME), what action must the ME take if Service n°142 is 'available'?
Option 1: The ME shall initiate a location update procedure with the MME.
Option 2: The ME shall perform a reading procedure with EF5GNSWO_CONF and follow the authentication procedure as defined for 5G NSWO.
Option 3: The ME shall trigger an SMS notification to the user indicating NSWO availability.
Option 4: The ME shall automatically switch to WLAN for data offloading without user prompt.
Explanation: This is correct because when Service n°142 (indicating NSWO support) is 'available', the Mobile Equipment (ME) is required to read the configuration from the EF5GNSWO_CONF and then proceed with the authentication steps specifically outlined for 5G Non-seamless WLAN Offload, ensuring secure and proper setup of the offload feature.
