Cross-optimization in wireless mobile networks. In an embodiment, a demand map is received for each of a plurality of networks. The demand map represents demand at a plurality of geographic locations in at least one cell of the network. Based on the demand maps, an optimal transfer of demand is generated between the plurality of networks at one or more of the plurality of geographic locations at which the plurality of networks overlap. Then, one or more parameters, to be used by at least one of the plurality of networks in a handover procedure, is determined, so as to produce the optimal transfer of demand between the plurality of networks at the one or more geographic locations at which the plurality of networks overlap.
