Abstract

A method for determining latitude and longitude coordinates for geographic addresses input into an address book on a mobile device is provided. For each geographic address received for storing in a contact record, latitude and longitude coordinates are automatically determined and associated with the geographic address in a database of contact records. In some embodiments, for each geographic address to be input, the method first searches existing contact records for the geographic address and if the latitude and longitude coordinates for the geographic address are in an existing contact record, the contact record for the contact is cross-referenced to the existing record for accessing the latitude and longitude coordinates.

Claims

1. A method, in a mobile device, the method comprising:

receiving a geographic address for storing in a contact record of a database of contact records on the mobile device;

automatically determining latitude and longitude coordinates for the geographic address; and

in the database, associating the latitude and longitude coordinates with the geographic address.

2. The method of claim 1, further comprising storing the latitude and longitude coordinates for the geographic address in the database.

3. The method of claim 1, wherein determining the latitude and longitude coordinates comprises requesting the latitude and longitude coordinates from a location database.

4. The method of claim 1, wherein determining the latitude and longitude coordinates comprises first searching existing contact records in the database of contact records for the geographic address and if the latitude and longitude coordinates for the geographic address are in an existing contact record, cross-referencing the contact record to the existing contact record for accessing the latitude and longitude coordinates.

5. The method of claim 1, wherein determining the latitude and longitude coordinates comprises requesting the longitude and latitude coordinates from a location server over a wireless network.

6. The method of claim 1, further comprising displaying a location the geographic address on a map using a map application executing on the mobile device.

7. The method of claim 1, further comprising identifying the geographic address as a point of interest (POI).

8. The method of claim 1, further comprising producing a user perceptible alert to indicate that the mobile device is within a specified proximity of the geographic address.

9. The method of claim 2, wherein storing the latitude and longitude coordinates in the memory comprises storing the latitude and the longitude in the contact record for the geographic address.

10. The method of claim 1, further comprising a map application on the mobile device accessing the longitude and latitude coordinates from the database of contact records.

11. The method of claim 1, further comprising storing the latitude and longitude coordinates in a cache memory on the mobile device for use by a map application on the mobile device.

12. The method of claim 1, further comprising adding the contact record to the database of contact records.

13. The method of claim 1, further comprising requesting latitude and longitude coordinates for a plurality of geographic addresses in the database of contact records.

14. The method of claim 1, further comprising receiving an indication from a location server that the geographic address is incorrect, presenting a user interface providing user input options for correcting the geographic address, receiving an input from the user interface indicating a corrected address and updating any contact record comprising the geographic address with the corrected address.

15. A mobile device comprising:

a user interface configured to receive a geographic address for storing in a contact record of a database of contact records on the mobile device;

a memory for storing the database;

a look up component configured to automatically determine the latitude and longitude coordinates for the geographic address upon receipt of the geographic address and associate the latitude and longitude coordinates with the geographic address in the database.

16. The mobile device of claim 15, wherein the user interface is a receiver for receiving communications over a wireless network.

17. The mobile device of claim 15, further comprising a cache memory for use by a map application in which the latitude and longitude coordinates can be temporarily stored.

18. A system comprising a mobile device and a location server,

the mobile device comprising:

a user interface configured to receive a geographic address for storing in a contact record of a database of contact records on the mobile device;

a lookup component configured to communicate with the location server to request and receive latitude and longitude coordinates for the geographic address from the location server; and

a memory configured to store the latitude and longitude coordinates for the geographic address,

wherein the lookup component is configured to associate the latitude and longitude coordinates in the memory with the geographic address,

and the location server comprising;

an input configured to receive the request from the lookup component;

a processor configured to determine the latitude and longitude coordinates for the geographic address using a location database;

an output configured to output the latitude and longitude coordinates to the lookup component.

19. The system of claim 18, wherein the location server and the mobile device communicate over a wireless network.

20. The system of claim 18, wherein the processor of the location server is configured to output suggestions for corrections to the geographic address if the geographic address is not recognized as valid by the processor.
