Abstract

A method provides for real-time asset location tracking. An asset in a wide area network, be it a utilities network or a communication network, registers itself with a network management center. The registration process includes identification of a physical location of the asset usable for mapping and tracking the asset.

Claims (49)

1. An asset tracking system comprising:

a computer processing unit; and

a computer-readable medium that stores computer-executable instructions that, when executed by the computer processing unit, cause the computer processing unit to perform operations comprising:

receiving, from an asset, via a dynamic host configuration protocol relay of a router, a packet comprising a mac-layer address of the asset and an internet protocol address of the router, wherein a gateway address field of the packet is left blank by the asset and filled in by the dynamic host configuration protocol relay of the router with the internet protocol address of the router,

determining an internet protocol address mapped to the mac-layer address of the asset,

assigning, to the asset, the internet protocol address mapped to the mac-layer address of the asset,

transmitting, to the asset, via the dynamic host configuration protocol relay, an acknowledgement packet comprising the internet protocol address assigned to the asset,

receiving, from the asset, an association request,

based at least in part on receiving the association request from the asset, providing, to the asset, using the internet protocol address assigned to the asset, a request for a geographical location of the asset and for a status of the asset, the geographical location of the asset and the status of the asset being previously unknown by the asset tracking system,

receiving, from the asset, in response to the request, the geographical location of the asset and the status of the asset, wherein the geographical location of the asset is determined by the asset using a location detector coupled to the asset, and

passing the geographical location of the asset and the status of the asset to a data repository.

2. The asset tracking system of claim 1 , wherein the asset tracking system communicates with the asset by way of a wireless transceiver associated with the asset.

3. The asset tracking system of claim 1 , wherein the operations further comprise updating information related to the asset in the data repository to reflect the geographical location of the asset, yielding updated information.

4. The asset tracking system of claim 3 , wherein the updated information is defined in terms of longitude and latitude.

5. The asset tracking system of claim 1 , wherein the location detector comprises a global positioning system receiver coupled to the asset.

6. The asset tracking system of claim 1 , wherein the asset is a product selected from a group of products consisting of a piece of electronic equipment and software.

7. The asset tracking system of claim 1 , wherein the asset is an equipment component of a telecommunications network.

8. The asset tracking system of claim 1 , wherein the asset is an equipment component of a utilities network.

9. The asset tracking system of claim 8 , wherein the utilities network is selected from a group of utilities networks consisting of:

a water utilities network;

an electric utilities network; and

a gas utilities network.

10. The asset tracking system of claim 1 , wherein the operations further comprise determining, from the status of the asset, whether the asset requires work.

11. The asset tracking system of claim 10 , wherein the work is selected from a group of types of work consisting of:

service;

repair;

replacement; and

upgrade.

12. A method comprising:

receiving, by an asset tracking system comprising a computer processing unit, from an asset, via a dynamic host configuration protocol relay of a router, a packet comprising a mac-layer address of the asset and an internet protocol address of the router, wherein a gateway address field of the packet is left blank by the asset and filled in by the dynamic host configuration protocol relay of the router with the internet protocol address of the router;

determining, by the asset tracking system, an internet protocol address mapped to the mac-layer address of the asset;

assigning, by the asset tracking system, to the asset, the internet protocol address mapped to the mac-layer address of the asset;

transmitting, by the asset tracking system, to the asset, via the dynamic host configuration protocol relay, an acknowledgement packet comprising the internet protocol address assigned to the asset;

receiving, by the asset tracking system, from the asset, an association request;

based at least in part on receiving the association request from the asset, providing, by the asset tracking system, to the asset, using the internet protocol address assigned to the asset, a request for a geographical location of the asset and for a status of the asset, the geographical location of the asset and the status of the asset being previously unknown by the asset tracking system;

receiving, by the asset tracking system, from the asset, in response to the request, the geographical location of the asset and the status of the asset, wherein the geographical location of the asset is determined by the asset using a location detector coupled to the asset; and

passing, by the asset tracking system, the geographical location of the asset and the status of the asset to a data repository.

13. The method of claim 12 , wherein the asset is an equipment component of a telecommunications network.

14. The method of claim 12 , wherein the asset is an equipment component of a utilities network.

15. The method of claim 14 , wherein the utilities network is selected from a group of utilities networks consisting of:

a water utilities network;

an electric utilities network; and

a gas utilities network.

16. The method of claim 12 , further comprising determining, from the status of the asset, whether the asset requires work.

17. The method of claim 16 , wherein the work is selected from a group of types of work consisting of:

service;

repair;

replacement; and

upgrade.
