Area construction of mobile communication systems generally requires many propagation measurements to define the base station (BS) parameters such as the transmission power of the pilot signal or the antenna tilt angles. In recent years, to reduce the amount of area construction and optimization work, automated area construction methods were proposed [1-5]. However, these methods only considered controlling the transmission power or the antenna tilt angles of the BS and only control the cell size. Therefore, when applying these methods to complicated environments such as those requiring arbitrary shaped cells, BSs must be sufficiently sectorized beforehand to achieve flexible coverage area design. Achieving a flexible design is a difficult task because the BS is stationary under normal conditions and to achieve sufficient sectorization large, complex, and high cost instruments and control system would be required. In order to address this issue, this paper proposes a new automated area construction method that controls the horizontal-plane antenna pattern of the BSs. This method utilizes data reported from mobile terminals to define the antenna pattern. Since the proposed method not only controls the cell size but also the cell shape, more flexible area design is achieved.
