Abstract

The invention refers to a specialised mobile terminal ( 1 ) intended to be localised by means of a suitable equipped telecommunications network ( 2 ). The mobile device ( 1 ) only implements the functions required for location definition and can be activated both remotely and possibly locally by the user of the device ( 1 ). The device ( 1 ) may also comprise a display to view the localisation data determined by means of the network.

Description

technical field [0001] The invention relates to a dedicated mobile terminal intended for use in a telecommunication network, said mobile terminal having means for locating the mobile terminal based on data of a predetermined type transmitted by said mobile terminal. Background technique [0002] Various mobile terminal positioning systems and methods are known in the prior art. For example, the international patent application published under WO0018148 describes a method for locating a mobile terminal, which is a cellular telephone (handset). According to this known method, by comparing the radio frequency data collected by the user's cellular phone (RF fingerprint or handset RF data) with the RF data contained in a reference database (reference RF fingerprint), and by assigning location, to determine the location of the user's cell phone, the value of the reference RF fingerprint closest to the value of the cell phone, wherein each RF fingerprint is determined relative to ...
