1. A method of generating an alert for a trailer, comprising:
- receiving, at a tracking system via a satellite communication from a mobile terminal affixed to said trailer, a motion detection report that indicates that said trailer has departed from an origin location, said motion detection report also including information that enables identification by said tracking system of a position of said trailer;
transmitting a message from said tracking system to a dispatch system, said message including a trailer identifier associated with said motion detection report;
identifying, by a dispatch system, a truck that has been assigned to said trailer having said trailer identifier;
polling, by said dispatch system, said identified truck for a position;
determining whether a position reported said identified truck in response to said polling is in proximity to said identified position of said trailer; and
generating an alert if said reported position of said identified truck is not in proximity to said identified position of said trailer.

Abstract
A system and method for generating an alert signal for a trailer. Proper truck/trailer matching is based on a proximity analysis between position reports for a truck and position reports for a trailer. In one embodiment, this proximity analysis is triggered by a detection of movement in a trailer. In the proximity analysis, unexpected deviations in proximity between a truck and a trailer would lead to a generation of an alert signal that is sent to the appropriate management system for investigation.

7. A system for generating an alert for a trailer, comprising:
-
a polling system that polls a truck for a position, said truck being identified based on a trailer identification contained within a motion detection position report, said motion detection position report being generated by a mobile terminal on a trailer that detects motion by said trailer, said motion detection position report being received by a tracking system from said mobile terminal via satellite, wherein said tracking system alerts said polling system of said motion of said trailer; and a proximity analysis system that determines whether a reported position of said identified truck is in proximity to a reported position of said trailer, wherein if said reported position of said identified truck is determined not to be in proximity to said reported position of said trailer, said proximity analysis system generates an alert. - View Dependent Claims (8, 9, 10, 11)

12. A method of generating an alert for a trailer, comprising:
-
receiving, via a satellite communication network, a motion detection report that indicates that said trailer has departed from an origin location; identifying, based on said received motion detection report, a position of said trailer; identifying, based on an identification of said trailer from said received motion detection report, a truck that has been assigned to said trailer; polling said identified truck from a centralized location; determining, at a location remote from said identified truck, whether a position reported by said identified truck in response to said polling is in proximity to said identified position of said trailer; and generating an alert if said reported position of said identified truck is not in proximity to said identified position of said trailer. - View Dependent Claims (13, 14, 15, 16, 17)
