A set of reporting features are specified for implementation by lower-level Self-Optimizing Network (SON) functions to support the observation of network SON algorithms by high-level SON functions (e.g., OAM functions). The lower-level SON functions may be operative to adjust local parameters related to the network element serving area and/or capacity. The reported SON algorithm events and measurements can be defined such that they can be used by the higher-level SON function to resolve conflicts and control the lower-level SON functions. Some embodiments specify SON function reporting features and their configuration in the framework of the 3GPP defined Itf-N interface specification.
