The General Packet Radio Service (GPRS) and Enhanced GPRS (EGPRS), the packet services of the Global System for Mobile Communications (GSM), are dominant standards for packet data support in evolved second-generation cellular systems. This thesis presents traffic engineering concepts for cellular packet radio networks that are applied but not limited to the standards GPRS and EGPRS and can be integrated into the radio interface capacity planning process. They are based on a comprehensive performance evaluation of Internet and Multimedia applications for the relevant cell scenarios, system parameter settings and protocol options that are expected for the evolution of GPRS and EGPRS networks. Additionally, optimized algorithms for traffic management and quality of service management, comprising connection admission control as well as scheduling, are developed. Their performance is evaluated and compared to existing implementations. From the traffic performance analysis, based on the existing and optimized system models, traffic engineering rules are derived. They can be used for quantitative radio interface dimensioning by network operators, equipment vendors or system integrators. Examples for the application of the traffic engineering rules are presented for GPRS evolution scenarios and an EGPRS introduction scenario. While the examples are based on the existing standards GPRS and EGPRS, the concepts developed in this thesis are valid for all packet radio networks. The traffic performance evaluation of mobile packet data services is a complex problem, because non-Poissonian traffic characteristics, dynamic behavior of lower layer protocols and the effects of the radio channel have to be considered. The author has solved this problem by the development of the emulation tool GPRSim. This comprises the implementation of the GPRS and EGPRS protocols and load generators for typical GPRS/EGPRS usage. The tool allows to study the existing and evolved systems in their natural environments with the appropriate radio coverage, mobility and typical traffic volumes and permits to analyze own approaches in the improvements and introduction of new features.","abstract_html":"Cellular packet radio networks are presently introduced and further developed to support mobile Multimedia applications and mobile Internet access.
