This initial paper introduces basic questions and alternative approaches to replace today’s circuit switched TETRA core network with an NGN-based core network. The paper presents first results from an R&D project, which is carried out in collaboration of Rohde & Schwarz Professional Mobile Radio GmbH, the Research Group for IP-based Communication Systems at Ostfalia University of Applied Sciences in Wolfenbüttel and the Institute for Communications Technology at TU Braunschweig, Germany. The project is funded by the Federal Ministry of Economics and Technology (BMWi, Germany) in context of the ZIM program (Zentrales Innovationsprogramm Mittelstand).
