Abstract
Universal Mobile Telecommunication System (UMTS) as a 3rd generation mobile telecommunications system is designed to provide mobile Internet access to the user. In this paper, the World Wide Web (WWW) browsing session as one mobile data service application is examined for performance analysis by simulations. A WWW traffic model is presented as the basis of a WWW load generator. This traffic load generator integrated into an event driven, bit accurate UMTS Radio Interface Simulator (URIS) is presented. The simulator is based on a detailed implementation of the standardized UMTS protocol stack extended by the Transmission Control Protocol (TCP) and the Internet Protocol (IP). Simulation results of quality of service parameters like delay and throughput depict the performance of mobile Internet access over UMTS. Of special concern is the interaction of TCP retransmissions with the Radio Link Control (RLC) Automatic Repeat Request (ARQ) mechanisms.
