Gateway as interface for communications networks

摘要

The system has a computer controlled gateway (26) for coupling central units (24, 46) of respective communication networks (10, 30) with each other. The gateway has a memory unit (32) for intermediate storage of an address of a communication unit (18) of a subscriber (16). A conversion unit (33) converts an address of another subscriber (28) at the communication network (30). A transmitting unit (35) transmits the converted address to the central unit (46) for establishing a connection. Independent claims are also included for the following: (1) a gateway for coupling central units of communication networks (2) a method for connecting communication units of different communication networks.
