|Abstract:||The impressive growth of the number of users in cellular mobile telephony and Internet promises an exciting potential for a technology that combines both innovations. Within the next few. years, there will be an extensive demand for high-speed wireless data services. General Packet Radio Service (GPRS) is a new bearer (carrier) service for Global System for Mobile communications (GSM) that greatly improves and simplifies wireless access to packet data networks, e.g., to the Internet. It applies a packet radio principle to transfer user data packets in an efficient way between GSM mobile stations and external packet data networks (PDNs). This thesis gives an overview of the basic concepts, architecture and the protocols of GPRS and its various performance measures. In particular, the performance measures that are dependent on the RLC/MAC layer design are discussed. RLC/MAC layer is the most important part of GPRS protocol stack, as it dictates the multiplexing capability of the system, on which the system throughput depends. The results are based on a simulation model comprising RLC/MAC layer design as the main module. In the simulation model, two performance characteristics of the GPRS are measured, viz., system throughput performance and packet bit rate performance. It has been shown that GPRS provides bandwidth-efficient support for bursty applications like web access. It multiplexes different users on the same channel and at the same time allocates more than one channel to a single user, if the user requests higher data rate. The software is written in C++, and runs under LINUX environment. It makes use of GIMP Tool Kit (GTK+) and Graphics Drawing Kit (GDK) for the graphical interface.|
