Abstract

A wireless telecommunications system is disclosed that provides both telecommunications service and navigational assistance to travelers. In particular, the present invention addresses three common navigation problems. First, to aid a traveler who takes the same trip infrequently, the present invention records the movement of the traveler during one trip and, thereafter, provides navigational assistance on how to recreate the trip again at a later time. Second, to aid a traveler in making the homeward portion of a trip, the present invention records the outward-bound portion of the trip and, thereafter, provides navigational assistance on how to get home. And third, to aid a traveler who is trying to recreate the trip of another traveler, the present invention records the movement of one traveler when taking a trip and, thereafter, provides navigational assistance to other travelers on how to recreate the trip taken by the first. In general, the present invention performs two distinct steps. In accordance with the first step, the present invention records the movement of a wireless terminal associated with a traveler as the traveler makes a trip. In accordance with the second step, the present invention generates a set of navigational directions based on a previously recorded trip, which directions indicate either how to recreate the trip or how to backtrack the trip. Those directions are then transmitted to a wireless terminal that is associated with a traveler who desires the directions.

Claims

1. A method comprising:

receiving a request to record a plurality of waypoints for a first wireless terminal as said first wireless terminal moves during a trip;

locating said plurality of waypoints for said first wireless terminal;

recording said plurality of waypoints;

receiving a request to cease recording said plurality of waypoints; and

providing wireless bidirectional, voice, telecommunications service to said first wireless terminal.

2. The method of claim 1 wherein said request to record is received from said first wireless terminal.

3. The method of claim 1 wherein said request to record is accompanied by an identifier for said trip.

4. The method of claim 1 further comprising receiving a request from said first wireless terminal to increase the frequency with which said plurality of waypoints are being recorded.

5. The method of claim 1 further comprising receiving a request to generate a set of directions to recreate said trip based on said plurality of waypoints.

6. The method of claim 5 further comprising transmitting said set of directions to said wireless terminal.

7. The method of claim 5 further comprising transmitting said set of directions to a second wireless terminal.

8. The method of claim 5 further comprising:

locating said first wireless terminal; and

transmitting a warning messages to said first wireless terminal when said wireless terminal deviates from said set of directions.

9. The method of claim 1 further comprising receiving a request to generate a set of directions to backtrack said trip based on said plurality of waypoints.

10. The method of claim 8 further comprising transmitting said set of directions to said wireless terminal.

11. The method of claim 8 further comprising transmitting said set of directions to a second wireless terminal.

12. A method comprising:

recording a plurality of waypoints for a first wireless terminal as said first wireless terminal moves during a trip;

generating a set of directions to recreate said trip based on said plurality of directions; and

transmitting said set of directions to said first wireless terminal; and

providing bidirectional, voice, wireless telecommunications service to said first wireless terminal.

13. The method of claim 12 further comprising transmitting said set of directions to a second wireless terminal.

14. The method of claim 12 further comprising:

tracking said first wireless terminal; and

transmitting a warning messages to said first wireless terminal when said wireless terminal deviates from said set of directions.

15. The method of claim 12 wherein said set of directions are oral.

16. An apparatus comprising:

a location service controller for receiving a request to record a plurality of waypoints for a first wireless terminal as said first wireless terminal moves during a trip, and for receiving a request to cease recording said plurality of waypoints;

a location determining server for locating said plurality of waypoints for said first wireless terminal;

a location service database for recording said plurality of waypoints; and

a wireless switching center through which said location determining server locates said plurality of waypoints for said first wireless terminal.

17. The apparatus of claim 16 wherein said request to record is received from said first wireless terminal.

18. The apparatus of claim 16 wherein said request to record is accompanied by an identifier for said trip.

19. The apparatus of claim 16 further comprising a base station for transmitting said set of directions to said wireless terminal.

20. The apparatus of claim 16 further comprising a base station for receiving a request to increase the frequency with which waypoints are recorded.

21. An apparatus comprising:

a location service database for recording a plurality of waypoints for a first wireless terminal as said first wireless terminal moves during a trip;

a location service controller for generating a set of directions to recreate said trip based on said plurality of directions; and

a base station for wirelessly transmitting said set of directions to said first wireless terminal and for providing bidirectional, voice, wireless telecommunications service to said first wireless terminal.

22. The apparatus of claim 21 further comprising a location determining server for tracking said first wireless terminal.

23. The apparatus of claim 21 wherein said base station transmits a warning message to said first wireless terminal when said wireless terminal deviates from said set of directions.

24. A method comprising:

generating a set of directions for a trip based on a plurality of waypoints;

transmitting said set of directions to a first wireless terminal;

locating said first wireless terminal while said first wireless terminal travels on said trip; and

transmitting a warning message to said first wireless terminal when said wireless terminal deviates from said set of directions.

25. An apparatus comprising:

a location service database for recording a plurality of waypoints for a first wireless terminal as said first wireless terminal moves during a trip;

a location service controller for generating a set of directions to recreate said trip based on said plurality of directions; and

a base station for transmitting said set of directions to said first wireless terminal;

wherein said base station transmits a warning message to said first wireless terminal when said wireless terminal deviates from said set of directions.

26. A method comprising:

providing bidirectional, voice, wireless telecommunications service to a wireless terminal;

recording the movement of said wireless terminal as it makes a trip; and

providing navigational assistance to said wireless terminal based on said trip.
