Method, System and Module for Locating a Telecommunications Terminal

摘要

A system for locating a communications terminal ( 10 ). The system comprises a location hybridization module ( 14 ) which comprises: a spatial filter ( 142 ); a temporal filter ( 141 ) for the geographical location adapted to compare a time corresponding to the age of the latest geographical location with a first predetermined maximum time and, in the event of a positive comparison result, to compare said time corresponding to the age of the latest geographical location with a second predetermined maximum time greater than said first predetermined maximum time; a speed filter ( 145 ) adapted to compare the speed at which said terminal ( 10 ) is moving with a predetermined maximum speed; a module ( 144 ) for estimating the uncertainty as to the geographical location; and a selection module ( 143 ) adapted to select either the area defined by the latest geographical location or the network-location area. Application is to mobile telephone services that need to know the location of the terminals.
