TOPOLOGICAL NETWORK DESIGN OF MOBILE COMMUNICATION-NETWORKS

The rapidly changing tariffs and networking technologies creates the n eed for ongoing planning, configuration and management of networks as one the most strategic resources. So the availability of a totally fle xible and productive tool for network topology optimization becomes mo re important than before. This paper presents requirement analysis for development of a network topology design tool and introduces TND-Tool as a tool fulfilling the proposed requirements. First, philosophy beh ind the tool and its requirement model which uses Hatley and Pirbhai m ethod are explained. Second, organization of the tool, i.e. needed mod ules and their structure are described such as representation, data ba se, optimization, cost-calculation and graphical user interface. Third , operational capabilities of the tool are presented. Fourth, heuristi cs for topological design of the fixed part of cellular mobile communi cation networks GSM900, the European mobile standard, and DCS1800 are shown. Fifth, performance analysis and new and special features of the tool will be presented.
