An advanced approach for QoS analysis in UMTS radio network planning

This paper presents a novel analysis concept for UNITS radio network performance evaluation. In particular a mix of multi-rate circuit switched (CS) and packet switched (PS) service types is considered. A flexible way of modeling different Quality of Service (QoS) policies taking costs for bit-rate adaptation into account is introduced. All constraints and limits important with regard to network performance are considered. The simulation is based on the "Monte-Carlo Method". Fast evaluation of individual snap-shots of the system is achieved by carrying out calculations on cell basis. This leads to a considerably higher rate of convergence and also a lower computational effort per iteration compared to state-of-the-art computations on connection basis. Furthermore, an additional gain is achieved by a highly linear modeling of the system.
