Topology discovery and management and SON orchestration
First Claim
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.

Abstract
Systems and methods are disclosed for managing an aggregated self-organizing network (A-SON). In such, a plurality of small cells is grouped into clusters using available topology information. In one implementation, a subset of clusters is assigned to groups of a first type, such that the clusters within a group of the first type have minimal RF connectivity. For example, scanning or updating of RF parameters may then be coordinated such that adjacent clusters do not scan or update simultaneously but clusters within groups of the first type do have at least partially overlapping scans or updates. Similarly, subsets of clusters may be assigned to first and second groups of a second type, such that the clusters within a first group of the second type have sufficient coverage to provide RF connectivity to clusters within the second group, if the second group encounters a service interruption. Other benefits are also described.
