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

1. A method for tracking assets in a wide area network, the method comprising:

generating an asset identifier;

storing the asset identifier in a database;

receiving a self-initiated asset registration request from an asset upon installation thereof,

receiving asset location information from the installed asset; and

correlating in the database, the asset location information with the identifier corresponding to that asset.

2. The method of claim 1, wherein said asset location information includes Global Positioning System (GPS) data obtained by the asset.

3. The method of claim 1, further comprising:

generating mapping information from correlated asset identifier information and asset location information; and

displaying a map including asset identification information for assets that have registered in a given region.

4. The method of claim 3 further comprising:

displaying asset status information on said map.

5. The method of claim 4 further comprising:

generating an alert based on status information regarding an asset.

6. A method for tracking equipment to be installed in various communication networks, the method comprising:

storing a plurality of unique equipment identifiers in a database, each unique equipment identifier having a particular piece of equipment associated therewith;

receiving a self-initiated registration request from a first piece of equipment upon installation thereof, said registration request identifying said first piece of equipment;

detecting whether said first piece of equipment corresponds to any of the pieces of equipment for which unique identifiers are stored in the database;

prompting said first piece of equipment to identify its location when a unique identifier for said first piece of equipment is detected in the database;

receiving location information from said first piece of equipment; and

storing the received location information in said database.

7. The method of claim 6 further comprising:

generating data representative of a map of a region; and

combining location information from said database with said data representative of said map to provide an equipment map.

8. The method of claim 6 further comprising:

monitoring a status of said first piece of equipment; and

storing status information regarding said first piece of equipment, to be correlated in said database with the unique identifier corresponding to said first piece of equipment and to the location of said first piece of equipment.

9. The method of claim 8 further comprising:

generating data representative of a map of a region;

combining location information from said database with said data representative of said map to provide an equipment map.

10. The method of claim 9 further comprising:

displaying status information for a piece of equipment identified on said equipment map.

11. A method for registering a piece of equipment in a cellular communication network, the method comprising:

maintaining a database of network equipment, said database including an identifier for each of a plurality of pieces of equipment;

receiving a self-initiated registration request for a first piece of equipment upon installation thereof;

receiving asset location information from the installed first piece of equipment; and

updating said database to reflect a location of said first piece of equipment using the asset location information.

12. The method of claim 11 wherein said location is defined in terms of longitude and latitude.

13. The method of claim 11 wherein said location is defined in relation to another piece of equipment, the physical location of which is known.

14. The method of claim 11 wherein said first piece of equipment comprises a base station.

15. The method of claim 11 wherein said first piece of equipment comprises a remote unit.

16. The method of claim 15 wherein said remote unit comprises a transceiver for fixed wireless communications.

17. A computer-usable medium tangibly embodying computer-executable instructions for implementing a process comprising:

maintaining a database of installed network assets, wherein at least one the assets automatically registers itself with the database using a process including;

following initial power on after installation of the asset, issuing a self-initiated request to be associated with a pre-determined asset identifier recognized by a database manager; and

providing its location to the database manager.

18. The computer-usable medium of claim 17, wherein the asset obtains its location using a GPS receiver coupled to the asset.

19. The computer-usable medium of claim 17, further comprising displaying a representation of the asset graphically within a map.

20. A method for managing a plurality of network assets, comprising:

forming a record in a database corresponding to an asset to be installed in a network;

following installation of the asset, receiving a self-initiated association request from the asset;

in response to the association request, referring to the record to obtain identifying information for the asset;

providing the identifying information to a network management system; and

requesting location information for the asset to be provided to the network management system.

21. The method of claim 20, wherein the asset is a base station.

22. The method of claim 20, wherein the asset location information includes Global Positioning System (GPS) data obtained by the asset.

23. The method of claim 20, further comprising displaying the location information in a geographical map format in a graphical user interface.
