Optimization of the coverage and capacity performance of the network represents an important Self-Organizing Networks (SON) use case, which requires appropriate support functions in the 3GPP specifications. The present document studies Network Management (NM) centralized Coverage and Capacity Optimization (CCO) SON function with the focus on necessary support in the 3GPP specifications. The NM centralized CCO function would help operators in reducing OPEX related to the maintenance and optimization of network coverage and capacity by automating these functions. NM centralized CCO function would observe network coverage and capacity performance, automatically detect problems and intervene with necessary actions or raise a notification toward the operator, when operator action is needed.

The present document summarizes the result of the study on "Enhanced Network Management (NM) centralized Coverage and Capacity Optimization". A CCO function that resides outside the NM is out of the scope for this study.
