  • Patent number: 8756624
    Abstract: When the set-top box (STB) has been switched on, registration and authentication with the provider (IDP) are carried out (1, 2, 3). Following successful authentication, a piece of authentication information is then sent (4) to the set-top box (STB), which the set-top box (STB) sends (5) to a service provider (SP1) for registration. The service provider (SP1) then sets up (6) a connection to the provider (IDP) of the registration and authentication function in order to verify the authentication information and to request guidelines for charging, and the provider (IDP) of the registration and authentication function sends (7) confirmation to the service provider.

  • Publication number: 20070223501
    Abstract: In a method for bidirectional transmission of data between a data processing device and a router data is transmitted over a plurality of sections. Data is transmitted over a first section between the data processing device and an access point via an air interface in accordance with a predefined first data transmission method. The data is transmitted over a second section between the access point and a central control unit via a cable-based connection in accordance with a predefined second data transmission method. The data is transmitted over a third section between the central control unit and the router in accordance with a predefined third data transmission method. The access point has a first layer for data transmission in accordance with the first data transmission method and layers hierarchically above the first layer for data transmission in accordance with the first data transmission method are disposed in the central control unit.

  • Publication number: 20050144021
    Abstract: The invention relates to a method for charging for Internet services, wherein the Internet users have access to the Internet via servers of an Internet provider and use the fee-paying services of various providers. According to said method the Internet provider refers the Internet users to pre-established providers. When a service is ordered by an Internet user from a pre-established provider, an order ID is issued by the computer of the user and said order ID is transmitted to the service provider and the Internet provider, thereby enabling anonymous use of services and ensuring a secure charging method.
