Method for data exchange with a mobile asset considering communication link quality
First Claim
1. A method of data exchange between a data center and a mobile asset, the method comprising:
- determining a location of a mobile asset;
determining a communication link quality at the determined location of the mobile asset;
predicting a communication link quality at the location based upon an existing communication link quality database relating location to communication link quality; and
selecting a packet size for data transfer with the mobile asset in response to the predicted communication link quality and the determined communication link quality.

Abstract
A method for data exchange with a mobile asset wherein the communication link quality at the location of the mobile asset is measured at the time of the data transfer. The packet size for the data transfer is selected in response to the communication link quality. The current communication link quality measurement may be used alone or in combination with historical communication link quality data for selecting the data packet size. Communication link quality may be determined repeatedly and the packet size reset accordingly in response to changes in the link quality. A difference between the current communication link quality and historical link quality data may trigger appropriate corrective action, such as identifying the source of intentional or unintentional jamming.

9. A method of data exchange between a data center and a mobile asset, the method comprising:
-
establishing a database correlating historical communication link quality data and location data; determining current communication link quality data for a location; comparing the current communication link quality data with the historical communication link data in the database for the location to determine a difference; and selecting a communication link operating parameter responsive to the difference for use in controlling a communication link quality between the data center and the mobile asset. - View Dependent Claims (10, 11, 12)
