Abstract
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.
