for each of a plurality of network layers receive demand map information for the network layer, wherein the demand map information comprises cell load level and signal quality or throughput information at a plurality of geographic locations in multiple cells in each of at least two of the network layers;

for one or more of the plurality of network layers, receive one or more objectives used in determining an optimal transfer of demand in multiple cells between the plurality of network layers at a plurality of geographic locations at which the plurality of network layers overlap;

analyze load distributions and at least one performance parameter in each of the partial overlap areas for the multiple cells;

determine the parameters for optimal transfer of devices from one network layer to other layers in each of the partial overlap areas for the multiple cells in each network layer based on both the load conditions and performance parameters, wherein the optimal transfer of demand is determined to achieve the one or more objectives using the at least one hardware processor and powerful computing tools, including cloud computing, over a plurality of iterations until one or more objectives are satisfied;

determine one or more parameters to be used by at least one of the plurality of network layers to produce the optimal transfer of demand between at least two of the plurality of network layers in multiple cells at the one or more geographic locations at which the plurality of network layers overlap; and

deliver the set of one or more parameters to the at least one network layer through an interface with at least one network layer.
