1. A method of managing an aggregated self-organizing network (A-SON), comprising:

  • grouping a plurality of small cells into clusters using available topology information;

    assigning a subset of clusters to groups of a first type, such that clusters within a group of the first type have minimal radio frequency (RF) connectivity;

    coordinating scanning or updating of RF parameters such that adjacent clusters do not scan or update simultaneously but clusters within the groups of the first type do have at least partially overlapping scans or updates;

    at a small cell, detecting a change in a parameter in an overlay macro cell of one of the clusters within the group of the first type;

    determining if any other small cells in the A-SON have the overlay macro cell in their topology; and

    for other small cells that have the overlay macro cell in their topology, updating small cell parameters with at least the changed parameter.
