Abstract:
1. A method for monitoring data transfer performance, comprising the steps of: (a) receiving at a vehicle a message that is sent to the vehicle over a wireless communication system and that has associated with the message an initiation time at which the message was initially sent; (b) determining a receipt time at the vehicle indicating when the message was received at the vehicle; (c) sending latency information from the vehicle to a central facility, the latency information being associated with a message latency representing the difference between the receipt time and the initiation time; (d) determining location information associated with the vehicle's location at the time the message was received at the vehicle; and (e) associating the latency information with the location information, wherein the association provides a latency map that represents the association of the latency information with the location information.
