Question: What is the expected behavior of a Mobile Management (MM) entity in a mobile station when it receives a MM STATUS message?
Option 1: The MM entity will initiate a state transition and perform specific actions visible from the radio interface.
Option 2: The MM entity will ignore the message and not take any action.
Option 3: The MM entity will respond with a CM SERVICE PROMPT message.
Option 4: No state transition or specific action shall be taken as seen from the radio interface, but local actions are possible.
Explanation: According to the specification, when an MM entity receives a MM STATUS message, it does not trigger any state transition or specific action visible from the radio interface. However, local actions within the mobile station are still possible. This behavior is in line with the implementation-dependent options for handling MM STATUS messages in the network.
