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.

Claims

1. A method of optimizing the quality of a cellular network, the method comprising 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.

2. An optimization method according to claim 1, wherein said local performance indicator at a point represents the data rate or the spectral efficiency at said point.

4. A computer program including instructions for executing the steps of the optimization method of claim 1 when said program is executed by a computer.

5. A computer readable recording medium having recorded thereon a computer program including instructions for executing the steps of the optimization method according to claim 1.

3. A device for optimizing the quality of a cellular network, the device comprising means for implementing, in iterative manner so long as it is possible to improve a global quality level of said network that depends on parameters of said network:

means for modifying said parameters;

means for estimating at least one local performance indicator at a plurality of points of the network, as a function of parameters of the network;

means for estimating said global quality level for said parameters on the basis of an estimate of a local quality level at each of said points and for said parameters, said local quality levels depending exclusively on said local performance indicators; and

means for storing said parameters corresponding to said optimum global quality level.
