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.
