Abstract

The present invention is directed to a method and system for providing off-board navigational information from a network server to a mobile communication device, such as a cellular phone. Specifically, upon receiving from the mobile communication device the real time location of the mobile communication device and a location or identification of a destination, the network server transmits to the mobile communication device routing information as well as audible navigation voice prompts. In accordance with the preferred embodiment, the routing information includes maneuver information for traveling from the real location of the mobile communication device to the destination, and the audible navigation voice prompts provide data for generating audible turn-by-turn instructions for traveling from the real time location of the mobile communication device to the destination.

Claims

1-24. -24. (canceled)

25. A method for providing routing directions to a mobile communication device, comprising:

receiving, from a mobile communication device, a routing information request including identification of a voice file stored in a physical memory of said mobile communication device;

recalculating, with a server, routing information for said mobile communication device; and

transmitting, to said mobile communication device, said routing information excluding said voice file stored in said physical memory of said mobile communication device.

26. A method for providing routing directions to a mobile communication device according to claim 25, wherein:

said physical memory is a cache memory.

27. A method for providing routing directions to a mobile communication device according to claim 25, wherein:

said voice files are pronunciation codes.

28. A method for providing routing directions to a mobile communication device according to claim 25, wherein:

said routing information request includes GPS data indicating a geographic location of said mobile communication device.

29. A method for providing routing directions to a mobile communication device according to claim 25, wherein:

said routing information further includes map data to generate a graphic map on said mobile communication device.

30. A method for providing routing directions to a mobile communication device according to claim 25, wherein:

at least a portion of said routing information is Extensible Markup Language (XML) data.

31. A method for providing routing directions to a mobile communication device according to claim 25, wherein:

said routing information request is triggered in response to said mobile communication device straying from a previously calculated routing information.

32. A method for providing routing directions to a mobile communication device, comprising:

transmitting, from a mobile communication device, a routing information request including identification of a voice file stored in a physical memory of said mobile communication device;

receiving, from a server, recalculated routing information excluding said voice file stored in said physical memory of said mobile communication device.

33. A method for providing routing directions to a mobile communication device according to claim 32, wherein:

said physical memory is a cache memory.

34. A method for providing routing directions to a mobile communication device according to claim 32, wherein:

said voice files are pronunciation codes.

35. A method for providing routing directions to a mobile communication device according to claim 32, wherein:

said routing information request includes GPS data indicating a geographic location of said mobile communication device.

36. A method for providing routing directions to a mobile communication device according to claim 32, wherein:

said routing information further includes map data to generate a graphic map on said mobile communication device.

37. A method for providing routing directions to a mobile communication device according to claim 32, wherein:

at least a portion of said routing information is Extensible Markup Language (XML) data.

38. A method for providing routing directions to a mobile communication device according to claim 32, wherein:

said routing information request is triggered in response to said mobile communication device straying from a previously calculated routing information.
