Abstract Third generation mobile radio networks as presently installed for the first time present ubiquitous data services at acceptable bandwidth. The most important aspects of such systems have been analysed in research projects during the past couple of years. This thesis is a contribution to a deeper understanding of the interaction of the radio resource control algorithms in todays radio networks of the Enhanced Datarates for GSM Evolution (EDGE) system. Special emphasis has been put on the optimisation of the Quality of Service (QoS). The thesis contributes solutions to some hitherto unsolved problems, e. g. investigations on the system performance considering the application of the EDGE Link Adaptation (LA) in comparison to the hybrid Automatic Repeat Request (ARQ) called Incremental Redundancy (IR). The deployment of power control is discussed and the limitations of operational scenarios for power control are shown. The influence of Frequency Hopping (FH) and Fractional Loading (FL) on packet services is examined for the first time. The influence of cell reselections on the system performance is investigated. A central chapter deals with simulation technique developed for the mentioned investigations. Special goals like multi-system simulations, large area scenarios and modelling accuracy as detailed as possible on almost all Open Systems Interconnection (OSI) layers shape the requirements towards the system. The focus in interference-limited systems is set on the modelling of the time-resolved interference situation with highest possible accuracy. The simulation scenarios and the evaluation methods obtain an own chapter in order to increase trust in the described optimisation methods. Next follows an elaborated presentation and discussion of the simulation results. The broad research area covered by this thesis only allows an introductionary investigation. The thesis concludes with an outlook at proceeding research areas. The EDGE emulator developed within this work is made available as source code under the Lesser GNU Public License (LGPL) in order to sponsor research on EDGE, the most successful mobile radio network worldwide.
