Abstract

A user selects a route between a starting point and a destination. A mobile handset monitors the user'"'"'s progress along the route by monitoring the location and movement of the handset and, optionally, sensor data, and by comparing this information to rules that define permitted or prohibited locations or movements or threshold sensor values. The handset uses one or more positioning systems, such as GPS, to ascertain its location. A server provides the handset with information to correct errors in the location information. If a rule fires, possibly indicating that the user is in danger, the handset attempts to ascertain the user'"'"'s wellbeing, warns the user to return to the prescribed route and begins sending the handset'"'"'s location to a server, which displays the information to a dispatcher who dispatches safety or security personnel to the user'"'"'s location. The handset and servers communicate via any available wireless channel(s).

Claims

1. A wireless handset comprising:

a positioning system; and

an application program configured to;

receive information describing a prescribed route;

use the positioning system and the route information to determine if the handset is within the prescribed route; and

notify a server if the handset fails to follow the prescribed route.

2. The wireless handset of claim 1, wherein the handset is configured to receive signals from at least one satellite and the positioning system is configured to ascertain a location of the handset using at least the satellite signals.

3. The wireless handset of claim 2, wherein the handset is configured to receive location correction information and the positioning system is configured use the location correction information in conjunction with the satellite signals to ascertain the location of the handset.

4. The wireless handset of claim 3, wherein the handset is configured to attempt to receive the location correction information over at least one of a plurality of channels.

5. The wireless handset of claim 4, wherein the plurality of channels comprises a data channel provided by a wireless telephone system, a wireless local area network and a signal from a satellite.

6. The wireless handset of claim 1, wherein the handset is configured to receive location information from the server and the positioning system is configured to ascertain a location of the handset using at least the positioning information.

7. The wireless handset of claim 1, wherein the handset is configured to receive location information from a wireless telephone system and the positioning system is configured to ascertain a location of the handset using at least the positioning information.

8. The wireless handset of claim 1, wherein the handset is configured to notify the server if the handset fails to follow the prescribed route by attempting to send a message to the server over at least one of a plurality of channels.

9. The wireless handset of claim 8, wherein the plurality of channels comprises a data channel of a wireless telephone system and a wireless local area network.

10. The wireless handset of claim 9, wherein the plurality of channels further comprises a wireless link through another wireless handset.

11. The wireless handset of claim 1, wherein:

the information describing the prescribed route includes information about a plurality of geographic boundaries; and

the determination of if the handset is within the prescribed route is based on a location of the handset relative to at least some of the geographic boundaries.

12. The wireless handset of claim 11, wherein the geographic boundaries define a plurality of route segments.

13. The wireless handset of claim 1, wherein:

the information describing the prescribed route includes information defining at least one check-in area and a time associated with each check-in area; and

the application program is configured to notify the server if the handset fails to arrive within the check-in area by the associated time.

14. The wireless handset of claim 1, further comprising a server configured to provide the information describing the prescribed route.

15. The wireless handset of claim 1, further comprising a server configured to:

receive a notification from the handset if the handset fails to follow the prescribed route; and

display information about the prescribed route.

16. The wireless handset of claim 1, further comprising a server configured to:

receive a notification from the handset if the handset fails to arrive within the check-in area by the associated time; and

display information about the prescribed route.

17. The wireless handset of claim 1, further comprising a server configured to:

receive location correction information from a satellite; and

provide the location correction information to the handset.

18. The wireless handset of claim 17, wherein the server is configured to provide the location correction information over a wireless local area network.

19. The wireless handset of claim 17, wherein the server is configured to also provide the location correction information over a data channel of a wireless telephone system.

20. The wireless handset of claim 1, further comprising a server configured to ascertain a location of the handset based on information about messages carried by a wireless local area network to or from the handset.

21. The wireless handset of claim 20, wherein the server is configured to ascertain the location of the handset based on information about messages carried by a wireless local area network to or from the handset and on information about the location of the handset from a wireless telephone system.

22. The wireless handset of claim 21, wherein:

the server comprises a web server configured to accept a request to configure a prescribed route; and

the server is configured to send the information describing the prescribed route to the handset.

23. The wireless handset of claim 22, wherein the server is configured to send the information describing the prescribed route via at least one of a plurality of channels.

24. The wireless handset of claim 23, wherein the plurality of channels comprises a data channel provided by a wireless telephone system and a wireless local area network.

25. The wireless handset of claim 1, further comprising a server configured to display information about the prescribed route if the server does not receive a message from the handset for a predetermined amount of time.
