System and method for updating geo-fencing information on mobile devices
First Claim
1. A method of automatically updating a set of geo-fences stored in the memory of a telematics system on a mobile asset that is wirelessly linked to a central station, wherein the telematics system has a location device and wherein one or more of the geo-fences of the set of geo-fences stored in the telematics system memory is a trigger geo-fence, comprising:
- determining the present location of the mobile asset with the location device;
determining at the asset whether the present location of the mobile asset is located within the area defined by one of the one or more trigger geo-fences stored in the telematics system memory; and
if the mobile asset is located within the area defined by one of the trigger geo-fences stored in the telematics system memory, updating via the wireless link the set of geo-fences stored in the telematics system memory based upon the present location of the asset and the trigger geo-fence within which the asset is located, by;
determining a general direction the asset is traveling based upon the present location of the asset within the area defined by the trigger geo-fence within which the asset is located;
selecting a replacement set of geo-fences based upon the general direction of the asset, such that the selected replacement set of geo-fences corresponds to areas in the general direction in which the asset is heading; and
replacing the set of geo-fences stored in the telematics system memory with the replacement set of geo-fences;
wherein the replacement set of geofences is selected from a library of sets of geo-fences stored on a storage device at the central station wherein at least one of the geo-fences in each of the sets of geo-fences in the library of geo-fences is a trigger geo-fence.

Abstract
A system and method of automatically replacing the geographic location of geo-fences stored in memory of a telematics system is described. The location of an asset is determined using an on-board telematics device with a location device. The location of the asset is compared with the location of predefined geo-fences stored in memory on the asset. When the asset is located within a geo-fence which triggers the replacement of geo-fences, the telematics system causes the asset to receive a new set of geo-fences, which replace the existing set of geo-fences in the telematics system memory. The operational cost of the system is reduced by minimizing communications charges when a reduced number of transmissions is needed to replace geo-fences stored in memory on the asset.

19. A system for automatically updating a set of geo-fences on a mobile asset, the system comprising:
-
an asset having a telematics system having memory, a locating device, and a wireless asset communications system for sending and receiving messages, wherein a set of geo-fences is stored in the telematics memory and wherein one or more of the geo-fences is a trigger geo-fence; a central station having a library of sets of geo-fences and a central station wireless communications system for sending and receiving messages, wherein at least one geo-fence in each set of geo-fences in the library is designated as a trigger geo-fence; wherein the locating device determines the present location of the asset, wherein the telematics system determines whether the present location of the asset is within the area defined by one of geo-fences of the set of geo-fences stored in the telematics memory; wherein the telematics system causes the set of geo-fences in the telematics memory to be updated if the asset is located within the area defined by one of the one or more trigger geo-fences stored on the telematics memory; and wherein the set of geo-fences in the telematics memory is updated by; determining a general direction the asset is traveling based upon the present location of the asset within the area defined by the trigger geo-fence within which the asset is located; selecting a replacement set of geo-fences from the library of sets of geo-fences based upon the general direction of the asset, such that the selected replacement set of geo-fences corresponds to areas in the general direction in which the asset is heading; and replacing the set of geo-fcnces in the telematics memory with the replacement set of geo-fences. - View Dependent Claims (20, 21, 22, 23)
