Method and apparatus for vehicle data transfer optimization
First Claim
1. For use with a self-powered land-based vehicle comprising a plurality of operational systems, wherein the vehicle is in selective communication with a remote site over a wireless limited bandwidth communications link, said method comprising:
- (a) sensing information indicative of the operation of the vehicle operational systems, constituting vehicle operational information;
(b) storing said operational information in a plurality of files;
(c) analyzing said operational information for it relevance to the health of the operational systems;
(d) setting priorities among the plurality of files based on their respective relevance to the health of the operational systems; and
(e) transmitting higher priority files to the remote site before transmitting lower priority files.

Abstract
An apparatus and method for identifying and transmitting time critical or high priority files from an on-board monitor aboard a vehicle. During operation of the vehicle, the on-board monitor collects and stores operational parametric information in the form of data files. The data files are transmitted to a remote site on a periodic basis or in response to certain predetermined conditions above the vehicle. To reduce the latency and delay times with transmitting the high priority files, those files are merged and transmitted before the transmission of relatively lower priority data files.

7. The method of claim 1 further comprising;
-
transmitting the highest priority file to the remote site;
selecting the next lower priority file from among the plurality of files;
transmitting the next lower prior files to the remote site; and
continuing to select and transmit files in descending order of priority until all of the plurality of files have been transmitted to the remote site.
