Abstract
An access network for mobile terminals includes a switch arranged to be connected to at least one external network and a local access network connected to a plurality of radio base stations. Each base station is arranged to enter into communication with mobile terminals, each terminal being arranged for receiving or sending user cells on a virtual channel identifiable by a fixed virtual path identifier and a specific virtual circuit identifier allocated thereto at the time a call is established. Signaling cells on a virtual channel are identified by a specific virtual path identifier and a specific fixed virtual circuit identifier. The switch allocates a virtual path identifier and a virtual circuit identifier to each user channel. To each signaling channel, the switch allocates a virtual path identifier equal to the virtual path identifier of the user circuit and a fixed virtual circuit identifier.
