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 for switching data packets, with allocated items of routing information, between connected communication terminal apparatuses and/or communication terminal apparatuses of connected local networks wherein the system includes at least one network coupling unit in which means are arranged for the evaluation of the routing information, for the switching of the data packets dependent on the result of the evaluation, and for the adaptation, in accordance with format, of the data packets. Through the advantageous arrangement of router functions in the network coupling unit, an economical switching-oriented connected can be made between a local network and a public network.

Communications system to transmitting data packets between affiliated communication terminals and/or communication terminals of affiliated local networks
