Abstract:
A system supporting wireless terminals in a data transmission network, said data transmission network comprising switches that control data transmission and data transmission connections therebetween, in which data transmission network the switches are divided into switch groups and arranged to form a hierarchical tree structure that enables the use of a Private Network-Network Interface protocol within said data transmission connections, said system including at least one wireless-specific switch supporting wireless terminals and at least one access point connected to said wireless-specific switch, wherein the arrangement formed by the wireless-specific switches and by the connections therebetween constitutes a parallel switch group arrangement in relation to other parts of said data transmission network, so that the wireless-specific switches belong both to a switch group of an ordinary switch group arrangement of said data transmission network and to a switch group arrangement supporting wireless terminals, so that some switches support both wireless and fixed terminal switching.
