Abstract: The invention relates to a communications system and a method for establishing a broadband connection, for example a multi-media connection between two or more users, by means of exchanges in a communications network, for example an ATM network. According to the invention, when the exchanges receive a request from a calling user to establish a broadband connection, said exchanges first establish a minimal connection between the users and once the minimal connection is in operation between the users, the requested broadband connection is established. The users of broadband network capacities, which have been reserved by the network at the request of the user, are billed during the call phase. Broadband connections of this type can receive a higher priority than the upgrade of minimal connections to complete connections. A voice connection comprising audio data constitutes for example a minimal connection. The broadband connection takes place for example between video telephones.

Abstract: In current telecommunications services, it is usual for the service provider of the initiator (e.g. the caller or the A-side) of the communications connection to determine the price and charge the A-side accordingly. The other subscribers are not usually charged. The A-side service provider pays a compensation amount (balance) to the B-side service provider. This fee charging and payment system is too rigid for modern communications services. The inventive method solves this problem.

Abstract: The inventive system comprises a graphic interface and a converter translating the graphic symbols entered by the user into a CPL script. The generated CPL script is fed into a CPL engine for controlling various IP based services. Not only the service to be executed, but also a definition of the semantics of the individual linguistic elements are enclosed via the converter.

Abstract: A method in which two terminals operated on a data transmission network store at least one electronic credit. With the aid of the credits, charge metering is performed. The electronic credits are transmitted with credit messages to control units, which check the validity of the credits and, depending on the result of the check, clear network resources.

Abstract: A method for using a data processing system as a function of an authorization, associated data processing system and associated program, wherein various authorization levels are defined for various user groups, a basic file contains the syntax for a basic authorization level, a priority file contains the syntax for a priority authorization level, the authorization level of a user is determined before the execution of the instructions of the user, and the basic file or the priority file is used, as a function of the authorization level, to define the instructions which the user is permitted to execute.
