Question: For a Mobile Equipment (ME) that supports NG-RAN via satellite access, what is the prerequisite for the ME to perform the reading procedure with EFMCHPPLMN as per the specified service requirement?
Option 1: The ME must be in an active communication session.
Option 2: Service n°144 is 'unavailable' and the ME is in idle mode.
Option 3: Service n°144 is 'available'.
Option 4: The ME only supports Access-Stratum (AS) functions.
Explanation: This answer requires understanding of conditions for network access. The correct answer, 'Service n°144 is available', directly aligns with the prerequisite for the ME to perform the reading procedure with EFMCHPPLMN when supporting NG-RAN via satellite access, highlighting service availability's importance in determining device behavior in telecom networks, especially with specialized access methods like satellite.
