Self optimization of layer 3 filtering in wireless networks

A method for optimizing layer 3 filtering of handover measurements, said method comprising the following steps - memorizing layer 3 filtered measurements of a predefined set of handover measurements, layer 3 filtering using a first layer 3 filter coefficient (K); - performing an adaptive filtering on the said predefined set of handover measurement so as to obtain an adaptively filtered set of measurement; - searching a layer 3 filter coefficient so that the layer 3 filtered measurements fit with the adaptively filtered measurements, found layer 3 filter coefficient being said second layer 3 filter coefficient; - using the said second layer 3 filter coefficient for layer 3 filtering of handover measurements.
