The development of telecommunication systems during the past two decades has been from the circuit switched towards the packet switched paradigm. Many operators have now started the paradigm shift in the telephone networks by moving to packet based technologies. This new approach is often called Next Generation Networks (NGN). NGN enables the network operators to run all services on one network, i.e. voice, data and video.
In this paper, transformation to NGN in Iceland Telecom’s network will be described. A cost model of the telecommunications system has been developed enabling cost and benefits analysis of transforming the network to NGN. Methods of optimisation will be described and their application to find the optimal number of nodes and their positions. The optimisation yields the network structure that results in the lowest possible operational cost and the model can show how deviations from the optimum will affect the cost. Feasibility of NGN can be assessed by comparing the cost of NGN migration to that of maintaining the current telephone network.
