LOCATION-TRIGGERED ALERTS FOR MOBILE COMMUNICATION DEVICES

摘要

Requests to issue alerts may be stored in a central database. Each request may identify a mobile communication device and a location at which an alert is to be issued when the mobile communication device is at the location. Mobile communication devices may repeatedly report their current location to the central database. In response to each report, the database may queried to determine whether a current location matches one in the database for the reporting mobile communication device. If so, an alert may be issued. Various types of alerts are described.
