Abstract
A telecommunication system and a method for authenticating a subscriber in a telecommunication system. The system includes a transmission network having subscriber identity codes of a first format and a first subscriber authentication procedure. An exchange of the transmission network is connected to a subsystem having subscriber identity codes of a second format and a second subscriber authentication procedure. The calls of the subscribers of the subsystem are routed through the transmission network and the exchange. The authentication of both subscriber types is enabled in the transmission network by locating the parameter generation algorithms of both the first and the second authentication procedure in a transmission network authentication center. The proper algorithm for each subscriber to be authenticated is selected on the basis of the type of the subscriber.
