Design Issues in All-IP Mobile Networks. Espoo 2007. VTT Tiedotteita – Research Notes 2376. 136 p. Keywords mobile networks, wireless telecommunication, All-IP, networking technology, resource management, services, positioning, quality of service, network dependability, propagation models Abstract This report summarises the results of the “Design of All-IP mobile network” (DAIMON) project, whose objective was to develop new networking technology solutions for an All-IP mobile network. The presented results form a complete concept for a future All-IP mobile system. The concept addresses both, the technical problems and social implications of such a system. The technical part focuses mainly on the radio propagation issues, radio resource management, services and QoS, positioning and heterogeneity. All addressed problems have been analysed from the user’s and network’s perspective. Several new methods and solutions, related to the above mentioned research areas, have also been developed and utilised in the project and are presented in this report. 3 Preface The work presented here was carried out in the “Design of All-IP mobile network” (DAIMON) project, which was part of the VTT Theme programme “Tulevaisuuden tiedonsiirtotekniikat”. The project reused results of earlier projects, e.g. CAUTION and CAUTION++ (EU IST projects). Some of the research activities were performed jointly with other parallel projects, i.e. T1MGIS, Mercone (TEKES project), Motive (EU project) and Magnet (EU project). The project was led by Prof. Pertti Raatikainen and supervised by Markku Sipilä. Seppo Horsmanheimo, Jari Hämäläinen, Leena Norros, Ilkka Norros and Urho Pulkkinen were the other members of the steering group of the project. They coordinated activities of several research teams within VTT: System usability team, Network performance team and Wireless systems team.
