A vehicle communication system for transferring a data message between a vehicle and an infrastructure communication network, the system comprising:

• a navigation device for determining a navigation route the vehicle is traversing;
• a plurality of expected roadside communication devices for relaying the data message to the vehicle traveling along a navigation route;
• and
• an application data server for controlling data message transmitted by the roadside communication devices;
• wherein the plurality of expected roadside communication devices are identified along the navigation route, wherein a respective time period that the vehicle will be within a transmitting range of each respective roadside communication device along the navigation route is estimated;
• wherein the data message is segregated into sub-units of data, each sub-unit of data to be relayed between a respective roadside communication device and the vehicle, and wherein a quantity of data contained in a respective sub-unit is based on an amount of data that may be communicated between the vehicle and the respective roadside communication device during the respective time period that the vehicle is within the transmitting range of the respective roadside communication device.
