Method for determining the location of persons equipped with a mobile terminal

摘要

The method involves transmitting a localizing message from a center (5) to a person's mobile device (1). The message is received by the mobile device over a mobile network (3) e.g. global system for mobile communicationsand universal mobile telecommunications system, without indicating receiving of the message by the mobile device or generating a ring tone. A secret contained in the message is tested by the mobile device. The message is answered with a reply message in which a determined location is included, by the device, if the test obtains a positive result. An independent claim is also included for a mobile device including a processor.
