Abstract

A method at a network element for creating a candidate geofence, the method including receiving a message at the network element, the message including geographic coordinates and an indication of an event value; adding the event value to a running value for a geographic region associated with the geographic coordinates, creating a total value; determining that the total value exceeds a threshold; and creating the candidate geofence for the geographic area.

First claim

The invention claimed is:

1. A method at a network node for creating a candidate geofence, the method comprising:
receiving a message at the network node, the message including geographic coordinates and an indication of an event value, the event value corresponding to an assigned significance of an event associated with the geographic coordinates, the event value being greater for events of greater significance, and the event value being lower for events of lower significance;
adding the event value to a running value for a geographic region associated with the geographic coordinates, creating a total value;
determining that the total value exceeds a threshold; and
creating the candidate geofence for the geographic area.

2. The method of claim 1 , wherein the event value is explicitly provided in the message.

3. The method of claim 1 , wherein the event value is implicitly provided in the message by having an event description in the message and the event value associated with the event description stored at the network node.

4. The method of claim 1 , wherein the geographic region comprises an area within a threshold distance of the geographic coordinates.

5. The method of claim 1 wherein the event value is based on a trigger event at a sender of the message.

6. The method of claim 5 , wherein the sender is associated with a container or vehicle, and wherein the trigger event is one of: a door open event; a door closed event; a stopping of the container or vehicle for at least a first time; a stopping of the container or vehicle for at least a second time, the second time being longer than the first time; an engine start event; an engine stop event; a light sensing event; or a cab light event.

7. The method of claim 1 , further comprising:
creating a report or alert by the network node regarding the creation of the candidate geofence.

8. The method of claim 1 , wherein the creating utilizes a plurality of geographic coordinates to create a shape for the candidate geofence.

9. The method of claim 8 , wherein the shape includes all received geographic coordinates within a threshold distance of each other.

10. A network node configured for creating a candidate geofence, the network node comprising:
a processor; and
a communications subsystem,

wherein the network node is configured to:
receive a message at the network node, the message including geographic coordinates and an indication of an event value, the event value corresponding to an assigned significance of an event associated with the geographic coordinates, the event value being greater for events of greater significance, and the event value being lower for events of lower significance;
add the event value to a running value for a geographic region associated with the geographic coordinates, creating a total value;
determine that the total value exceeds a threshold; and
create the candidate geofence for the geographic area.

11. The network node of claim 10 , wherein the event value is explicitly provided in the message.

12. The network node of claim 10 , wherein the event value is implicitly provided in the message by having an event description in the message and the event value associated with the event description stored at the network node.

13. The network node of claim 10 , wherein the geographic region comprises an area within a threshold distance of the geographic coordinates.

14. The network node of claim 10 , wherein the event value is based on a trigger event at a sender of the message.

15. The network node of claim 14 , wherein the sender is associated with a container or vehicle, and wherein the trigger event is one of: a door open event; a door closed event; a stopping of the container or vehicle for at least a first time; a stopping of the container or vehicle for at least a second time, the second time being longer than the first time; an engine start event; an engine stop event; a light sensing event; or a cab light event.

16. The network node of claim 10 , wherein the network node is further configured to:
create a report or alert by the network node regarding the creation of the candidate geofence.

17. The network node of claim 10 , wherein the network node is configured to create by using a plurality of geographic points to create a shape for the candidate geofence.

18. The network node of claim 17 , wherein the shape includes all received geographic coordinates within a threshold distance of each other.

19. A non-transitory computer readable medium for storing instruction code for creating a candidate geofence, which, when executed by a processor of a network node cause the network node to:
receive a message at the network node, the message including geographic coordinates and an indication of an event value, the event value corresponding to an assigned significance of an event associated with the geographic coordinates, the event value being greater for events of greater significance, and the event value being lower for events of lower significance;
add the event value to a running value for a geographic region associated with the geographic coordinates, creating a total value;
determine that the total value exceeds a threshold; and
create the candidate geofence for the geographic area.
