Abstract: An ordering scheme is described, for example an ordering and payment scheme for mobile communication devices. The ordering scheme enables an Internet shop or another service provider to issue binding offers to a mobile communication device or the like and to receive an acceptance of the offer from the mobile device. The acceptance is encrypted using a private key of mobile device and the offer may be encrypted using a private key of the service provider. The service provider liaises with a payment broker and a charging system for controlling the transfer of funds from the user to the service provider. An identity management system may be provided to control access to the modules of the ordering scheme.

Abstract: The document explains, inter alia, a method in which, for a target system having various functional units, model units are specified to simulate the various functional units. The model units respectively contain compiling functions, so that a method for automatically programming a target system is produced which can easily be changed, serviced and maintained.

Abstract: A method and an apparatus are provided for the secured provision of functions of a signaling network for distributed telecommunication applications. An application logic of a telecommunication network is separated from system components that are relevant to security by setting up the former on decentralized apparatuses of the communication network and the latter on central apparatuses of the communication network. Suitable communication measures between central and decentralized apparatuses ensure that centrally available functions can be called from an application logic which is implemented in a decentralized manner. Security functions for protecting the signaling network and/or a central apparatus are set up or utilized on central apparatuses.
