Abstract

One of the main advances of 3G networks like UMTS is the ability to support a large variety of different services. These services are subdivided in two domains, circuit-switched services and packet-switched services. The main application expected for packet-switched services is the browsing of the World Wide Web. The web traffic is usually described by quite sophisticated source traffic models and the packet arrivals on IP layer are determined by TCP. On the other hand, the planning process for UMTS networks relies on analytic methods or Monte Carlo simulations that assume the number of users to be Poisson distributed. The intention of this work is to examine if it is possible to apply the existing planning methods to web traffic. We are able to show that the Poisson assumption holds for the number of web users that simultaneously transmit over the air interface and that the resulting NodeB transmit power distribution is valid. We use the Monte Carlo simulation technique to evaluate the web capacity of an example UMTS network.
