The invention prevents the need for a subscriber to input a PIN to book a service with the purpose of managing this service from the subscriber side. This is achieved by using a mobile network terminal for the management. The mobile subscriber reports a subscriber number of a fixed network terminal to the service, in which the subscriber number thus reported is allocated to the mobile network subscriber so that the mobile network subscriber can thereafter use the fixed network terminal for the special service, namely by debiting an account opened by the service.
