Abstract: The invention relates to a method for charging for the use of a telecommunication service, as well as to a switching system, a service control point and a network management facility. A service request is transmitted from a subscriber (A) via a telecommunication network (KN) of a network operator to a service-providing unit (SAPP1) of the service provider. A charge unit (BILL) of the network operator administers the charge collection for the use of the telecommunication service. The service-providing unit (SAPP1) provides the requested telecommunication service only after receipt of a confirmation message from a authorization unit (AUT) of the network operator. The charge message (M6) with data relating to a charge for using the telecommunication service is transferred from the service-providing unit (SAPP1) to the charge unit (BILL) and the charge unit (BILL) collects the charge after the confirmation message has been received.
