Abstract

The present invention concerns a system and corresponding method for location estimation analysis within a communication network equipped with location estimation devices adapted to perform a location estimation for terminals, the system comprising reference position determination means (like GPS) adapted to derive reference position information for at least one specific terminal, location information determination means (LCS) adapted to derive location information for said at least one specific terminal, a neural network adapted to correlate said derived reference position information and location information and to output said correlation result.

Claims

1. A method for location estimation analysis within a communication network equipped with location estimation devices adapted to perform a location estimation for terminals, the method comprising the step of

deriving reference position information for at least one specific terminal,

deriving location information for said at least one specific terminal,

correlating said derived reference position information and location information using a neural network, and

outputting said correlation result.

2. A method according to claim 1, wherein said derived information is time stamped prior to correlating.

3. A method according to claim 1, wherein said deriving is performed in regular intervals.

4. A method according to claim 1, wherein said deriving is performed when needed.

5. A method according to claim 1, wherein said deriving is triggered by an event/observation.

6. A method according to claim 1, further comprising the steps

measuring the performance for said at least one specific terminal within the network, and

supplying the measured performance to said neural network for correlation.

7. A method according to claim 6, wherein

said measuring is performed by said specific terminal.

8. A method according to claim 6, wherein

said measuring is performed by a communication network device.

9. A method according to claim 1, wherein

said correlation result is used to correct a derived location information for an arbitrary terminal different from said specific terminal.

10. A method according to claim 1, wherein

said correlation result is used to change/optimize network configuration.

11. A system for location estimation analysis within a communication network equipped with location estimation devices adapted to perform a location estimation for terminals, the system comprising

reference position determination means (GPS) adapted to derive reference position information for at least one specific terminal,

location information determination means (LCS) adapted to derive location information for said at least one specific terminal,

a neural network adapted to correlate said derived reference position information and location information and to output said correlation result.

12. A system according to claim 11, further comprising means adapted to accomplish a time stamping of said derived information.

13. A system according to claim 11, wherein said reference position determination means and said location information determination means are operated in synchronized manners.

14. A system according to claim 11, wherein said deriving is performed when needed.

15. A system according to claim 11, wherein said deriving is triggered by an event/observation.

16. A system according to claim 11, further comprising

measurement means adapted to measure the performance for said at least one specific terminal within the network, and

transmission means adapted to supply the measured performance to said neural network.

17. A system according to claim 16, wherein

said measurement means is located at said specific terminal.

18. A system according to claim 16, wherein

said measuring means is part of the communication network.

19. A system according to claim 11, wherein

said correlation result is fed back to said location information determination means to correct a derived location information for an arbitrary terminal different from said specific terminal.

20. A system according to claim 11, wherein

said correlation result is fed back to a network management system to be used to change/optimize network configuration.
