The aim of the invention is to connect terminals to a communication system in a wireless manner by means of a data packet network. At least one transition device to which a short-range radio module is coupled, and a server for controlling connections to the terminals, are coupled to said data packet network. The transition device is provided with a coupling table comprising addresses of terminals which are situated within the radio coverage of the short-range radio module. The server comprises an allocation table in which a network address of the transition device which enables the terminal to be wirelessly reached is respectively allocated to an address of a terminal. According to the invention, a packet-based alignment protocol is provided in order to dynamically align the allocation table with the coupling table.

Arrangement for the wireless connection of terminals to a communication system

A communication system equipped with a central computer means is connected to a service central via a communication network, for example, a telephone network of ISDN network, for telecontrol thereof. For the information exchange between the service central and the communication system, a teletransmission module is arranged in the latter, this telecommunication module being connected to the central computer means via a computer/bus interface and via a PCM-oriented system/bus interface. An information transmission via different communication networks, preferably via the telephone network or via the ISDN network, can be set using the teletransmission module. Due to the central arrangement of the teletransmission module with different information transmission procedures for different communication networks and due to the control of the call setup and cleardown for different communication networks by the central computer means that is possible as a result thereof, externally connectable transmission equipment (for example, modems) including a call setup and cleardown controller provided for this purpose can be eliminated.
