1 Management System for Mobile Networks 河村一利 村田政雄 樋口晃治 黒河内文保 あらまし SON Abstract Fujitsu is working on the development of an integrated system to be used in the future for managing various communication networks. This paper introduces a system for managing one such communication network: a mobile network. It describes the current status of this development and how it could proceed in the future, based on the features of managing mobile networks. First, this paper gives a general introduction of systems for managing mobile networks, and then describes the features of managing networks and the problems involved. It goes on to explain the main points of various measures that can be used to solve these problems. Next, this paper explains the architectural concepts behind system and software configurations used to achieve these measures. It gives an overview of Self-Organizing Network (SON) that are characteristic of network management systems and that allow Fujitsu to differentiate itself from its competitors. The last part explains the concept of a system for managing mobile networks that can be used to develop an integrated management system. FUJITSU. 62, 4, p ,
