Abstract

A method and an apparatus are provided for determining location information of network equipment in a wireless communication system is provided. The method comprises estimating a parameter indicative of the location information for the network equipment based on a first beacon signal and a second beacon signal The first beacon signal may be detected before the second beacon signal from a transceiver associated with the network equipment and the second beacon signal.

Claims

1. A method of determining location information of network equipment in a wireless communication system, the method comprising:

estimating information indicative of a physical location of said network equipment based on a first beacon signal and a second beacon signal from a transceiver associated with said network equipment, said first beacon signal being detected before said second beacon signal.

2. A method, as set forth in claim 1, wherein estimating a information indicative of a physical location of said network equipment further comprising:

listening for said first and second beacon signals;

detecting a location of said network equipment based on said second beacon signal; and

storing said information indicative of the physical location with previously determined information indicative of the physical location of said network equipment.

3. A method, as set forth in claim 1, wherein further comprising:

using current location information for said network equipment based on said first and second beacon signals.

4. A method, as set forth in claim 3, wherein using current location information further comprises:

using physical location information of said network element, wherein said physical location information including at least one of physical information, latitude and longitude information.

5. A method, as set forth in claim 1, further comprising:

determining a cell identifier associated with said first and second beacon signals.

6. A method, as set forth in claim 1, further comprising:

determining a service set identifier associated with said first and second beacon signals.

7. A method, as set forth in claim 1, further comprising:

detecting a new beacon for said second beacon signal; and

in response to detecting said new beacon, storing the information indicative of the physical location of said network equipment.

8. A method, as set forth in claim 7, wherein detecting a new beacon further comprises:

detecting an indication of a network transition in said wireless communication system.

9. A method, as set forth in claim 8, wherein detecting an indication of a network transition further comprises:

detecting a change in a cell identifier in one of a GSM and UMTS system.

10. A method, as set forth in claim 9, wherein detecting a change in a cell identifier further comprises:

storing an old identifier associated with said first beacon signal and a new identifier associated with said second beacon signal together with current information indicative of the physical location of said network element.

11. A method, as set forth in claim 8, wherein detecting an indication of a network transition further comprises:

detecting a change in a service set identifier in a wireless local area network.

12. A method, as set forth in claim 11, wherein detecting a change in a service set identifier further comprises:

storing an old identifier associated with said first beacon signal and a new identifier associated with said second beacon signal together with current location information of said network element.

13. A method, as set forth in claim 1, further comprising:

using an indication of transition from a first beacon transmitter associated with said network equipment to a second beacon transmitter to determine said location information of said network equipment.

14. A method, as set forth in claim 13, further comprising:

determining said information indicative of the physical location of the network equipment based on triangulation.

15. A method, as set forth in claim 14, further comprising:

determining current information indicative of the physical location of said network equipment based on one or more previous measurements with the same beacon transition between said first and second beacon signals by averaging said one or more previous measurements instead of said triangulation.
