Method, communication terminal, router device, server device, Internet access and computer program for establishing and carrying out communication links between at least one terminal and the Internet

摘要

The present invention relates to a method, a communication terminal, a router device, a server device, an Internet access and a computer program for establishing and performing communication links between at least one terminal and the Internet. At the same time, several guest terminals can simultaneously use a router, hotspot or a LAN of any type and size (eg a private device or a complete city network) to provide free Internet access (FI) in compliance with legal monitoring measures (eg according to TKÜV ) without the need for precautions in the router and / or LAN. First, the guest device logs into the FI network and transmits the ID of its own service provider (GUEST ISP). In step two, the router automatically retrieves the IP address in question from a secure ISP Lawfull Address Resolution server, e.g. B. can be operated by the Federal Network Agency. In step three, the router allows the establishment of a secure (VPN) connection between the guest and only the guest ISP who provides internet access to the guest and performs the gÜM. This also allows a logical unbundling of the last mile, a clear division between the transport and service network (ISP) and a cost-effective space expansion with fast Internet. If completely based on IP is transmitted, with favorable router technology and fiber optic or radio link in the regional and WLAN in the connection area on DSL connection lines, DSL multiplexer DSLAM, analog and ISDN switching technology and monitoring facilities in the transport network can be completely dispensed with.
