The guarantee of telecommunications service is a mandate stipulated in Undang-Undang No.36 of 1999. Interconnection tariffs are no longer focused solely on voice and sms services, because the characteristics of service users are currently moving towards data services. The pricing model that is currently used in determining interconnection tariffs is basically intended for voice and sms services, so the model is not necessarily suitable if applied to Internet Protocol (IP) based services. This study is an evaluation of the models available in determining the most effective model for use in IP-based services. This study applies the Consistent Fuzzy Preference Relations (CFPR) method to determine the best alternative from IP-based interconnection pricing model. The CFPR method, which is a modification of the Analytical Hierarchy Process (AHP) method, guarantees the consistency of a comparison matrix of various criteria when using AHP. So that the alternative interconnection pricing model obtained in this study can be used as a reference by the regulator without doubting the consistency of the comparison of its criteria. Based on data processing, the most recommended Internet Protocol-Based Interconnection Tariff model is Bottom up -Long Run Average Incremental Cost (BU-LRAIC). This is because the model meets the criteria of being very good and fair in terms of technical, economic and social impacts.
