Abstract

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.
专用通道上Web流量的UMTS系统性能分析
基于WCDMA的3G蜂窝标准具有很大的灵活性,并且为不同类型的业务类别定义了多种逻辑和传输通道。本文研究了用于WWW业务的专用信道的性能。UMTS标准通过在随机接入信道(RACH)上的访问请求,指定实际流量使用专用信道(DCH)。通过仿真模型,从吞吐量、传输延迟、碰撞概率和阻塞概率作为网络负载的函数,研究了UMTS MAC在Web流量专用信道上的性能。同时分析了用户数量、资源数量等参数对UTRA- FDD性能的影响。
