Abstract

In this work, we develop an analytical model for the integration of real time and elastic traffic in a system supporting both UMTS R99 and HSDPA/HSUPA channels. We first develop models for the powers and throughputs, and then use them to study the dynamic evolution of the system by a Markovian model. We also study the impact of the interaction between uplink and downlink caused by the TCP ACKs carried by dedicated or shared channels. We apply our model to dimension the system for different traffic scenarios. In particular, we show how to determine the number of carriers that must be assigned to a base station in order to meet some blocking requirements, and whether they will be shared between R99 and HSPA or dedicated to one system.
