Method for monitoring the safety of travelers
First Claim
1. A method comprising:
- receiving a signal s1 at time t1 from a first telecommunications terminal that is at a first location;
predicting that the first telecommunications terminal will be at a second location at time t2;
when the signal s1 is received at time t2 from the second location, predicting that the first telecommunications terminal will be at a third location at time t3; and
when the signal s1 is not received at time t2 from a second location, verifying a status of a user of the first telecommunications terminal.

Abstract
A method is provided for monitoring the present location of a traveler at time t1, predicting a location at which the traveler is expected to arrive by time t2, and verifying the safety of the traveler. The safety verification is conducted if the traveler has not reached the expected location at time t2, if signal from the traveler is lost or if a message from the traveler is not received within a predetermined time period. In some embodiments of the present invention, verifying the safety of the traveler involves contacting the traveler at one or more telecommunications devices which the traveler is known to carry, contacting another person that is known to be accompanying the traveler, and if all else fails—alerting the local emergency response team.
