Self optimizing network (SON) framework for automated vertical sectorization

Dynamic Vertical Sectorization (VS) is a flexible way of cell densification used to enhance system capacity in temporally and spatially varying overload situations. An automated control mechanism in the context of Self Optimizing Network (SON) is required to execute the sectorization only when there is a demand for extra capacity and the sectorization brings benefit in a dynamically varying traffic condition. The SON mechanism requires proper real-time modeling of the system performance with respect to VS activation/deactivation via monitoring the traffic situation and commonly used system parameters.
