VSC configuration methodology. This figure represents a periodical methodology which allows the implementation and elimination of the VSC. It consists of a cell traffic evaluation, then in a second phase, we identify the hotspots of UEs based on the previous cellular traffic analysis. If the detected hotspot is new in the cell, a highly directive beam will be focused on it, i.e., a VSC is implemented. If hotspots in the database have disappear, the associated VSCs are removed
