A SON element which is operative to carry out at least two different SON functions is provided, wherein each of the SON functions is associated with at least one SON related action, and wherein a SON related action, initiated by triggering a SON function, would have been adversely affected by another SON related action, initiated by triggering another SON function, had the SON element not affected a modification in operating conditions of the cellular network, wherein the SON element is operative to: (a) assign priorities to the different SON functions; (b) assign different weights to the SON related actions; and (c) coordinate execution of SON related actions, that when executed are carried out in a way that does not breach the priorities hierarchy and the weights' order assigned to the SON related actions, thereby improving operation of the cellular network.
