Performance analysis of the UMTS system for Web traffic over dedicated channels

摘要

The WCDMA based 3G cellular standards have a great flexibility and a variety of logical and transport channels defined for different types of traffic classes. In this paper performance of the dedicated channel for WWW traffic has been investigated. The UMTS standard specifies the use of dedicated channels (DCH) for the actual traffic, through access requests placed on the random access channel (RACH). Performance of the UMTS MAC on dedicated channel for Web traffic has been studied through simulation models in terms of throughput, transfer delay, collision probability and blocking probability as a function of network load. Also the effect of other parameters like number of users and number of resources on the performance has been analyzed for UTRA- FDD.
