A packet switched multi-mode mobile communication network and fixed and
mobile devices for use therewith are disclosed. Each of the mobile vehicle
equipment and a base station packet switch are coupled to respective data
terminal equipment which generates packet data messages. The packet data
messages have message characteristics associated therewith. Each of the
mobile vehicle equipment and the base station packet switch have an
intelligent switching node incorporated therein for selecting which of a
plurality of radio frequency transmission paths to use in transmitting the
packet data message to the other of the mobile vehicle equipment and the
base station packet switch. Each of the plurality of radio frequency
transmission paths has transmission path characteristics associated
therewith. The intelligent switching nodes select the radio frequency
transmission path as a function of the message characteristics of the
packet data message and as a function of the transmission path
characteristics of the plurality of radio frequency transmission paths.
