Abstract

Devices and methods are disclosed which relate to the gathering and recording of network availability and attributes in a location in order to define location based services. Registration logics onboard mobile communications devices collect network data as they roam inside and outside of their home cellular network. The registration logic sends this data to a registry in the form of a data message. The registry is updated by each instance of a received message. The aggregation of this data allows the system to adaptively learn about network availability in geographic locations. The data collected may also assist in the recovery of lost or stolen phones since the phone location is frequently updated.

Claims

1. A system for improving the quality of location-based services, comprising:

a mobile communications device with at least one module for detecting and communicating with a wireless network;

a registration logic onboard the mobile communications device; and

a registry in communication with the mobile communications device.

wherein the registration logic communicates the status of available wireless networks at a geographic location to the registry.

2. The system in claim 1, wherein the registration logic communicates with the registry over a data connection.

3. The system in claim 2, wherein the data connection is a WiFi connection.

4. The system in claim 2, wherein the data connection is a cellular data connection.

5. The system in claim 2, wherein the data communication is in the form of an XML message.

6. The system in claim 2, wherein the available wireless network is one or more of a cellular network, a WiFi network, a BLUETOOTH network, and a femtocell.

7. The system in claim 1, wherein the registry communicates through a server.

8. The system in claim 1, wherein the geographic location is determined by a GPS module onboard the mobile communications device.

9. The system in claim 1, wherein the registration logic resides on a dedicated memory.

10. A system for improving the quality of location-based services, comprising:

a server;

a database in communication with the server; and

a registration program coupled to a mobile communications device capable of two-way communication with the server,

wherein the registration program collects data concerning a plurality of available networks at a geographic location which is sent to the server to be stored in the database.

11. The system in claim 10, wherein the registration program communicates with the server over a data connection.

12. The system in claim 11, wherein the data connection is a WiFi connection.

13. The system in claim 11, wherein the data connection is a cellular data connection.

14. The system in claim 11, wherein the data sent to the server by the registration program is in the form of an XML message.

15. The system in claim 11, wherein the plurality of available networks is one or more of a cellular network, a WiFi network, a BLUETOOTH network, and a femtocell.

16. The system in claim 10, wherein the geographic location is determined by a GPS module onboard the mobile communications device.

17. The system in claim 10, wherein the registration program has its own dedicated memory.

18. A method of improving location-based services using a mobile communications device, comprising:

detecting a plurality of available wireless networks within the range of the mobile communications device, a plurality of network attributes, and a geographic location of the mobile communications device;

composing a data message which includes information concerning the plurality of available wireless networks, the plurality of network attributes, and the geographic location; and

delivering the data message to a registry.

19. The method of claim 18, wherein the available wireless network is one or more of a cellular network, a WiFi network, a BLUETOOTH network, a femtocell.

20. The method of claim 18, wherein the delivering is accomplished over a data connection.

21. The method of claim 20, wherein the data connection is a WiFi connection.

22. The method of claim 20, wherein the data connection is a cellular data connection.

23. The method of claim 20, wherein the data message is in the form of an XML message.

24. The method of claim 18, wherein the geographic location is determined by a GPS module onboard the mobile communications device.

25. The method of claim 18, wherein the registration logic contains its own memory.

26. The method of claim 18, wherein the registry communicates with the registration logic through a server.

27. The method in claim 18, further comprising saving the data message to a memory for later sending.

28. The method in claim 27, further comprising sending the data message once a data connection is found.
