Abstract: A method for controlling and operating a vending machine that incorporates a mobile radiocommunication transmit/receive unit and can be called from a user's mobile telephone unit over a mobile telephone network via an abbreviated mobile telephone number affixed on the vending machine.

Abstract: The invention relates to methods and systems for selectively controlling network selection in an area covered by at least two mobile communication networks. According to the first method, the area which is to be covered is divided up into zones and a specific code is allocated to each individual zone. Said codes are stored in a storage system and the network is selected on the basis thereof. Alternately, a correlation is made between information on a subscriber identification module (SIM) and signals from a cell broadcast channel which is used to select the network.

Abstract: A method is provided for a mobile telephone users to pay small individual fees for certain content when surfing the Internet using a mobile telephone terminal, for example, a WAP-enabled terminal. The method establishes a payment gateway which is accessible by the mobile telephone Internet user via the mobile telephone terminal and by a provider via a provider server. Customer data of the user is held securely in a database of the payment gateway and is not transmitted over the Internet or held in the mobile terminal. A micropayment account opened at a bank is synchronized continuously with the payment gateway. To provide payment of fees for content, a reservation of a certain amount is made in the payment account via the payment gateway and is authorized by the user to the provider allowing the provider to debit amounts against the reservation.

Abstract: A cordless communication system includes a mobile terminal of a public mobile communication system and a base station. The base station is connectable to a public fixed network and compatible at an air interface with the mobile communication system which has at least one authentication function. A read and write unit of the base station reads and writes from and to, respectively, at least one identification module. Sections of data of the identification module used in the base station are identical to sections of data stored on a chip card of an access-authorized mobile terminal. The read data from the identification module is processed through software implemented in the base station. The mobile terminal is authenticated with regard to the base station through the processed data, wherein the base station fulfills the same functions and tasks as a home location register and, respectively, an authentication center of the mobile communication system.

Abstract: The invention relates to a method and system for connecting subscribers participating in several telecommunication networks under one telephone number. The invention is characterized in that the subscriber data are stored in at least one telecommunication network and made available to the other telecommunication networks on request. To this end the invention provides for at least one of the telecommunication networks to have a data bank shared by all participating telecommunication networks.

Abstract: The invention relates to a method and a device for accessing a telecommunication network and for billing telecommunication services, whereby there are presented new processes, as compared to those of classical mechanisms of network providers, services are offered to their customers and fees are charged for providing the same. In this context the invention primarily concerns novel access mechanisms and access media to a telecommunications network, modified security mechanisms as well as innovative counting methods. The invention is characterized in that authentication methods are used in the telecommunication network, which permit a subscriber to certify at any one freely choosable point in time that a payment for a service which has been solicited or which is to be solicited, is provided or has already been provided.
