APPARATUS AND METHOD FOR ROUTING COMMUNICATIONS

摘要

A mobile telephone (1) is provided with a look-up table (1000) enabling the mobile telephone to select preferred routes for connecting outgoing calls on the basis of predetermined codes which populate the look-up table. When operating in a cellular communications network a communications channel may thereby be selected from a plurality of available channels and ongoing transmission of an outgoing call may be routed via further networks selected in accordance with the route codes. The look-up table may be stored in a SIM card of the mobile telephone and may be updated via transmission of data from a remote control centre via a cellular network or via a docking station (1300) to which the mobile telephone is releasably connectable. When the call is routed via a packet switching network, the routing code may comprise a string of network node addresses.
