Abstract
A method for determining an antenna beam angle for base stations of a radiotelecommunication system, notably of the cellular mobile radiotelephony system type. Each of the base stations defines a cell and has a transmission and reception antenna whose beam covers a sector in which mobile units can communicate with the base station. The antenna beam can be inclined, so as to modify the sector covered, via a dynamic antenna beam inclination control method. That method includes the steps of determining, a priori, an optimum inclination that is optimum in relation to the sector covered; estimating a cell load of the cell at a given instant; determining an instantaneous inclination at the given instant, as a function of the optimum inclination and the estimated load; controlling an instantaneous inclination of the antenna as a function of the instantaneous inclination determined.
