Question: In a Home (e)NodeB (H(e)NB), what action by the H(e)NB triggers the termination of an HPSIM session?
Option 1: Sending a particular STATUS command to the HPSIM signaling the start of termination procedure.
Option 2: Receiving a specific STATUS command from the HPSIM indicating session closure.
Option 3: Automatically after a predefined inactivity period within the HPSIM session.
Option 4: Upon receipt of an update failure for subscription-related information elements.
Explanation: The H(e)NB initiates the termination of an HPSIM session by sending a specific STATUS command to the HPSIM, signaling the start of the termination procedure. This is a deliberate network-side action to close the session, as per the defined protocol for managing HPSIM sessions in Home (e)NodeB environments.
