A network node, a network control node and methods therein for achieving load based signaling. The method performed by the network node includes determining a load level out of a set of predefined load levels based on a current load of the network node, where each load level corresponds to an estimated capability of the network node to handle signaling from at least one network control node. The method further includes indicating the determined load level to at least one network control node, thus enabling the at least one network control node to apply a signaling handling scheme towards the network node based on the indicated load level.
