Method, gateway, portal and terminal device for creating a communications connection between different communications networks

摘要

The method involves receiving address identification from a communication network, and accessing a transformation data set, in which address identification constituents of the communication network are assigned to address identification constituents of the other communication network. The constituents of the former network are automatically transformed to the constituents of the latter network based on the data set. The communication connection between terminals is established using the transformed address identification. An independent claim is also included for a terminal.
