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).
