Abstract

In a radio communication system with at least one radio network control device, at least one base station is connected to at least one user station by a radio communication interface. The base station(s) and the radio network control device are components of a base station subsystem. The radio network control device is connected to an access device for a core network. The radio network control device and the user station(s) have a service specific key that is preferably valid for several user stations, or in other words, the service specific key is not user specific.
