Abstract

Dynamically updated route information is provided to a user of a wireless communications device. The method involves receiving a destination location, determining a current location of the device, generating a route from the current location of the device to the destination location, and providing route information to the user representing the route from the current location to the destination location. Dynamic updating can be achieved by updating the current location of the device and dynamically updating the route information based on an updated current location of the device so as to provide dynamic route information to the user.

Claims

1. A method of providing route information for a wireless communications device, the method comprising steps of:

receiving a destination location;

determining a current location of the device;

generating a route from the current location of the device to the destination location; and

providing route information representing the route from the current location to the destination location.

2. The method as claimed in claim 1 further comprising steps of:

updating the current location of the device; and

dynamically updating the route information based on an updated current location of the device so as to provide dynamic route information.

3. The method as claimed in claim 1 wherein the receiving step further comprises receiving a default starting location for use in generating the route in the event that the device is unable to determine its current location.

4. The method as claimed in claim 2 wherein the receiving step further comprises receiving a default starting location for use in generating the route in the event that the device is unable to determine its current location.

5. A system for providing route information to a plurality of wireless communications devices communicatively connected to a communications network at different locations in the network, the system comprising:

a computing device communicatively connected to the communications network for enabling a sender to send a common destination location to the plurality of wireless communications devices, each of the devices comprising a positioning subsystem for determining a respective current location; and

a route information server communicatively connected to the network for transmitting route information to each wireless communications device in response to location data received from each wireless communications device, wherein the location data comprises the current location of the respective wireless communications device, representing a starting location, and the destination location.

6. The system as claimed in claim 5 wherein each wireless communications device is configured to update its respective current location and to dynamically update the route information based on an updated current location of the device so as to provide dynamic route information to the user.

7. The system as claimed in claim 5 wherein the computing device enables the sender to specify a default starting location for use in generating the route in the event that one or more of the wireless communication devices is unable to determine its respective current location.

8. The system as claimed in claim 5 wherein each wireless communications device enables its respective user to specify a default starting location for use in generating the route in the event that the wireless communication devices is unable to determine its current location.

9. The system as claimed in claim 5 wherein the positioning subsystem on the wireless communications device comprises a UPS receiver chipset.

10. A computer program product comprising code which, when loaded into memory and executed on a processor of a wireless communications device, is adapted to perform the steps of:

receiving a destination location from a sender;

determining a current location of the device;

generating a route from the current location of the device to the destination location; and

providing route information to the user representing the route from the current location to the destination location.

11. The computer program product as claimed in claim 10 wherein the code is further adapted to perform the steps of:

updating the current location of the device; and

dynamically updating the route information based on an updated current location of the device so as to provide dynamic route information to the user.

12. The computer program product as claimed in claim 10 wherein the receiving step further comprises receiving a default starting location for use in generating the route in the event that the device is unable to determine its current location.

13. The computer program product as claimed in claim 11 wherein the receiving step further comprises receiving a default starting location for use in generating the route in the event that the device is unable to determine its current location.

14. A wireless communications device for providing route information to a user of the device, the wireless communications device comprising:

a radiofrequency transceiver for receiving a destination location;

a positioning subsystem for determining a current location of the device;

a processor operatively coupled to memory for instructing the transceiver to communicate location data for the current location and the destination location to a route information server for receiving route information for a route from the current location of the device to the destination location; and

a user interface for providing the route information.

15. The wireless communications device as claimed in claim 14 wherein the positioning subsystem comprises a GPS receiver chipset.

16. The wireless communications device as claimed in claim 15 wherein the processor and memory interact with the GPS chipset to update the current location of the device in order to dynamically update the route information based on an updated current location of the device.

17. The wireless communications device as claimed in claim 15 wherein the radiofrequency transceiver also receives a default starting location for use in generating the route information in the event that the GPS chipset is unable to determine the current location of the device.

18. The wireless communications device as claimed in claim 16 wherein the radiofrequency transceiver also receives a default starting location for use in generating the route information in the event that the GPS chipset is unable to determine the current location of the device.

19. The wireless communications device as claimed in claim 15 wherein the user interface comprises a user input device to enable a default starting location to be specified for use in generating the route information in the event that the GPS chipset is unable to determine the current location of the device.

20. The wireless communications device as claimed in claim 16 wherein the user interface comprises a user input device to enable a default starting location to be specified for use in generating the route information in the event that the GPS chipset is unable to determine the current location of the device.

21. A wireless communications device for sending route information to a recipient computing device, the wireless communications device comprising:

a radiofrequency transceiver;

a user input device for receiving user input to define a destination location; and

a processor operatively coupled to memory for instructing the transceiver to communicate only the destination location to the recipient computing device whereby the recipient computing device uses the destination location and a current location of the recipient computing device to determine route information for a route from the current location of the computing device to the destination location provided by the wireless communications device.
