<p>A method and system for providing pre-emptive advice of charge messages to users of a communications system, via mobile terminals or fixed terminals. Each terminal has at least one physical and at least one functional connection in the communications system. The pre-emptive advice of charge messages are based on historical usage, administrative and operational information in the communications system and are sent to the user without user's request or initiation of the facility or service for which pre-emptive advice of charge is given.
