Question: What happens when a Mobility Management (MM) connection is interrupted while it's active?
Option 1: The MM sublayer immediately terminates the connection.
Option 2: The MM sublayer indicates to the call control entity that the current MM connection has been interrupted but might be re-established on request of call control.
Option 3: The MM sublayer automatically re-establishes the connection without any request from call control.
Option 4: The MM sublayer sends an error message to the User Equipment (UE) indicating a permanent failure.
Explanation: When a Mobility Management (MM) connection is interrupted while it's active, the MM sublayer may indicate to the call control entity that the current MM connection has been interrupted but might be re-established on request of call control. This allows for potential re-establishment of the connection if needed, rather than immediate termination or automatic re-establishment without consideration of the call control's needs.
