The invention relates to a method for supporting the mobility of a subscriber across a communication system comprising a communication terminal which is associated with a first communication device and can be registered when a log-on procedure is initiated by the input of log-on information relating to the subscriber, a second communication device for providing configuration data of the subscriber, and a packet-oriented network by which means the communication terminal is connected to the first and second communication devices. Once a successful registration has been carried out, the communication terminal is logged off the first communication device and associated with the second communication device.

Method for supporting the mobility of a subscriber across a communication system

The invention concerns a method and a device for requesting subscriber communication to a communication system. Said communication system comprises a communication terminal having a first transmission/reception unit for a radio interface and a portable device having a second transmission/reception unit for the radio interface, for data exchange. Data concerning an authentication of the subscriber are exchanged through the radio interface. Once authentication is successfully completed, the subscriber request for communication with the communication system is granted.

Method for requesting a subscriber communication to a communication system

A method for route searching from a calling subscriber of a first terminal that is connected to a first communications network to a terminal of a called subscriber. In this case, the terminal of the called subscriber, whose address for setting up a call is initiated by the first terminal, is connected to a second communications network. Call diversion to a diversion destination is activated for the terminal of the called subscriber, in which case the diversion destination is not assigned to the second communications network.
