A Study on Comparative Analysis on Interconnection charging and Settlement Methodology under NGN

It is important to set the new interconnection system under NGN. The traditional interconnection system is based on traffic, but this is not suitable for IP based service. Therefore, it is needed to ensure the universal access to network without trouble about the network topology. This paper prepares the evaluation criteria and evaluates the alternatives. Specifically, we deduce the alternatives and evaluates the alternatives of interconnection settlement system based on the condition of efficient interconnection, the retail price and access charging model, and the previous studies evaluating and examining the various alternatives . Finally, we evaluate each alternatives by the criteria.
