Abstract: This method of optimizing the quality of a cellular network includes at least one iteration, each iteration comprising: a step of estimating at least one local performance indicator at a plurality of points of the network as a function of parameters of the network; a step of estimating a global quality level of the network for said parameters on the basis of a local quality level as estimated at each of said points and for said parameters, said local quality level depending exclusively on said local performance indicators; said parameters being modified so long as the global quality level can be improved; and a step of storing said parameters corresponding to said optimum global quality level.
