Locating method and system
First Claim
1. Method of locating a radio terminal able to communicate with a plurality of radio base stations associated with respective cells under the supervision of at least one radio network controller receiving data intended for locating the terminal,at least one of the cells comprising predetermined cell portions, the base station associated with the said at least one of the cells comprising means for estimating a cell portion where the radio terminal is situated and for focusing signals for communications with the radio terminal selectively in the estimated radio cell portion,comprising the steps of:
- transmitting from the base station associated with the said at least one of the cells to the radio network controller at least one parameter intended for the locating of the terminal and relating to the estimated cell portion, andlocating the radio terminal as a function of at least the said parameter relating to the estimated cell portion.

Abstract
The method makes it possible to locate a radio terminal able to communicate with a plurality of radio base stations associated with respective cells under the supervision of at least one radio network controller receiving data intended for locating the terminal, at least one of the cells comprising predetermined cell portions. The base station associated with this cell comprises means for estimating a cell portion where the radio terminal is situated and for focussing signals for communications with the radio terminal selectively in this estimated radio cell portion. The method comprises steps of transmitting from the base station associated with the cell to the radio network controller at least one parameter intended for the locating of the terminal and relating to the estimated cell portion, and locating the radio terminal as a function of at least this parameter relating to the estimated cell portion.
