Abstract
A communications device (1) communicates with an access point (7) to gateway (21) and local area network (13) by a wired or wireless communications link (9). These components may, for example, be accommodated on a train or serve some other predefined area. Gateway (21) receives data packets from device (1) representing information for transmission via that device'"'"'s “home” communication system (15) to a destination device. The gateway (21) creates packet data protocol channels (27,29,31) with a plurality of communication systems (15,23) and (25) and sends the data packets received from the device (1) selectively over each of these communications channels (27,29,31). A link between a communications systems (23) and (25) allows the data packets to be forwarded to the communications system (15) where they are compiled by concentrator (49) for onward transmission. The communication systems (15,23,25) may be mobile or cellular communications systems.
