Wide area mobile communication networks with multiple routing mode options
First Claim
1. A packet switched mobile communication device for use on a terrestrial vehicle for communicating with a fixed communication device through a base station packet switch, the mobile communication device comprising:
- means for generating a packet data message for transmission to the fixed communication device using one of a plurality of radio frequency transmission paths, the packet data message having message characteristics associated therewith, each of the plurality of radio frequency transmission paths having transmission path characteristics associated therewith; and
an intelligent switching node located outside of the plurality of radio frequency transmission paths and coupled to the means for generating a packet data message, wherein the intelligent switching node selects, as a function of the message characteristics of the packet data message and as a function of the transmission path characteristics of each of the plurality of radio frequency transmission paths, a preferred one of the plurality of radio frequency transmission paths to be used for transmitting the packet data message to the fixed communication device.

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.
