Abstract
The goal of universal mobile telecommunications systems (UMTS) is the delivery of multimedia services to the mobile user. Each type of service requires its specific quality of service (QoS) to satisfy the mobile user. The QoS requirements are supported by several protocol layers. The interaction between radio resource management (RRM), medium access control (MAC) scheduling and transport format (TF) selection is presented. To study the interaction and dependencies, a typical mobile user application mix is examined for performance analysis by simulation. A UMTS radio interface simulator (URIS) is used, based on an emulation of the standardized UMTS protocol stack extended by the Transmission Control Protocol (TCP) and the Internet Protocol (IP). Simulation results of QoS parameters, such as delay and throughput, depict the performance of mobile applications over UMTS.
