[issue#] N/A
[problem] request_update & trigger_update_monitor should not be called directly from livebox interfaces.
[cause] request_update can be done by return NEED_TO_SCHEDULE, and trigger_update_monitor can be done by return OUTPUT_UPDATED.
[solution] Check the current operation, so the request_update and trigger_update_monitor will return if the operation is not done.
