LOCATION METHOD AND SYSTEM AND LOCATABLE PORTABLE DEVICE
First Claim
1. A location method for locating a portable device (from a server configured to communicate with said portable device through a wireless communication network, in which the method comprises the steps of:
- sending GPS assistance information from the server to the portable device through said wireless communication network;
obtaining in an A-GPS positioning module of the portable device a GPS signal from a satellite system;
calculating in said portable device a location of the device itself from said GPS signal and from the GPS assistance information sent by the server;
sending said location to the server;
wherein the method comprises the step of;
when the portable device stops, hibernating the A-GPS positioning module the transmission/receiving module and a microprocessor of said portable device managing said modules such that the battery is saved and the autonomy of the portable device is thus increased.
