Radio communication system and method for the operation thereof
In a radiocommunication system a first network element supports connection-oriented communication and is identified by a first address in a first format. A second network element supports connectionless communication and is identified by a second address in a second format. A network transmission unit and a data bank are also part of the radiocommunication system. To establish a connection between the first network element and the second network element, a connection-oriented link is set up between the network transmission unit and the second network element. Addresses in the first format are converted into the second format with the aid of the data bank.
