A SYSTEM FOR COMMUNICATION BETWEEN A FLEET OF VEHICLES (12, 14) AND A CENTRAL BASE STATION (18), WHERE EACH OF THE VEHICLES INCLUDES ONE OR MORE VEHICLE SUBSYSTEMS (31A-31N) CONNECTED TO A VEHICLE DATA LINK (32), IS DISCLOSED HEREIN. WITHIN EACH VEHICLE, MESSAGE PACKETS GENERATED BY VEHICLE SUBSYSTEMS (31A-31N) ARE PLACED UPON THE VEHICLE DATA LINK (32). EACH MESSAGE PACKET INCLUDES HEADER INFORMATION IDENTIFYING A GIVEN VEHICLE AND SUBSYSTEM THEREOF. THE MESSAGE PACKETS ARE TRANSMITTED FROM THE FLEET OF VEHICLES (12, 14) TO THE CENTRAL BASE STATION (18), AND ROUTED WITHIN THE CENTRAL BASE STATION (18) BASED ON THE HEADER INFORMATION. CONTROL INFORMATION AND THE LIKE MAY ALSO BE TRANSMITTED BY THE CENTRAL BASE STATION (18) FOR RECEIPT BY VARIOUS VEHICLE SUBSYSTEMS (31A-31N) WITHIN SELECTED ONES OF THE FLEET VEHICLES (12, 14). EACH MESSAGE PACKET GENERATED BY THE CENTRAL BASE STATION (18) INCLUDES HEADER INFORMATION IDENTIFYING AT LEAST A PARTICULAR FLEET VEHICLE AND VEHICLE SUBSYSTEM. THIS ALLOWS EACH MESSAGE PACKET TO BE RETRIEVED BY THE SPECIFIED VEHICLE SUBSYSTEM BY WAY OF THE VEHICLE DATA LINK (32).FIGURE 2
