To locate a mobile terminal (MS1, MS2, . . . ) within a mobile
communication network comprising at least a radio base station (BTS1,
BTS2, . . . , BTSn), a set of physical dimensions are measured, which
identify, according to respective functions, the location coordinates (x,
y, z) of the mobile terminal. The method comprises the steps of:
generating, starting from said set of physical dimensions and respective
functions, a global locating error function (.phi.) which has a minimum
for values of said locating co-ordinates (x, y, z) corresponding with the
position occupied by said mobile terminal, seeking the minimum of said
error function (.phi.) by varying at least one of said locating
co-ordinates (x, y, z), and locating said mobile terminal in
correspondence with the value of said at least one locating co-ordinate
corresponding to said minimum.
