Patent ID: 7570971

Claim:
An arrangement for a wireless connection of terminal devices to a communication system, comprising: a data packet network for the transmission of data packets using network addresses valid within the network; a transition device coupled to the data packet network, the transition device comprises a short-range radio module and a coupling table, the short-range radio module locates a terminal device within range of the module, the coupling table includes an address of the located terminal device; a server coupled to the data packet network controls connections to the terminal device and controls roaming for the terminal device, the server includes an allocation table that comprises for each transition device: an aligned copy of the coupling table and a network address for the respective transition device such that the address of the located terminal device is associated with the copied table; and a packet-based alignment protocol for the dynamic alignment of the allocation table with the coupling table, wherein via the alignment protocol a content of the coupling table is transmitted to the server to dynamically update the allocation table thereby aligning the copy of the coupling table in the allocation table.
