Abstract
A communication system is proposed which, as its communication elements (KE) has a gatekeeper (GK), a gateway (GW) coupled to the gatekeeper (GK) and at least one communication unit (KEH) coupled to the gateway (GW), with the communication system being set up so that, to register a communication relationship of the communication unit (KEH) in the communication system (KS), a request message (ANF) is transmitted from the communication unit (KEH) via the gateway (GW) to the gatekeeper (GK), which is checked in the gateway (GW) for authenticity and in the gatekeeper (GK) for authorization.

22. A communication system, comprising the following communication elements:
-
a gatekeeper;
a gateway operatively connected to the gatekeeper; and
at least one communication unit operatively connected to the gateway, wherein the communication system is set up such that, to register a communication relationship of the communication unit in the communication system, a request message of the communication unit is sent via the gateway to the gatekeeper and is checked for authenticity in the gateway and for authorization in the gatekeeper. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
