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:
- 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 devices 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;
when the portable device is stopped, hibernating the A-GPS positioning module, a transmission/receiving module and a microprocessor of said portable device manage said modules, such that a battery of the portable device is saved and the autonomy of the portable device is thus increased; and
when the portable device is connected by means of an external cable to a vehicle, said portable device and said external cable form a locator device for an automotive environment, which is supplied from a battery of said vehicle.

Abstract
Location method for locating a portable device (1) from a server (2) configured to communicate with said portable device (1) through a wireless communication network (3), with the steps of: sending GPS assistance information from the server (2) to the portable device (1) through said wireless communication network (3); obtaining in an A-GPS positioning module (11) a GPS signal (4) from a satellite system (8); calculating a location of the device (1) itself from said GPS signal (4) and from GPS assistance information; and sending said location to the server (2). The method further comprises: when the portable device (1) is stopped, hibernating the A-GPS positioning module (11), the transmission/receiving module (12) and a microprocessor (15) managing said modules (11, 12), such that the battery is saved and the autonomy of the portable device (1) is thus increased; and when the portable device (1) is connected by means of an external cable (19) to a vehicle, said portable device (1) and said external cable (19) form a locator device for the automotive environment (10), which is useful as an anti-theft system which is undetectable due to being radio-electrically transparent.

41. A portable device comprising:
-
A-GPS global positioning means configured to receive a GPS signal from a network of GPS satellites; transmission/receiving means configured to connect with a wireless communication network and to receive therethrough, from a server, at least GPS assistance information and location requests; wherein said portable device can calculate its position from said GPS assistance information and from said GPS signal and can send said position to said server; wherein, the portable device comprises motion sensor means which can capture information that can be used for hibernating or interrupting the hibernation of said A-GPS positioning module and transmission/receiving module, according to the absence or presence of motion of the portable device, and which can capture a measurement of the gravity. - View Dependent Claims (42, 43, 47, 48, 51, 53, 54, 55, 56)
