Abstract

This chapter introduces traffic separation technique and presents several traffic separation approaches to transmit HSPA (HSDPA/HSUPA) traffic and UMTS Release 99 (R99) traffic over a shared access transport network. The traffic separation technique enables QoS differentiations of HSPA and R99 traffic, while aiming to achieve a maximum utilization of the transport resources. In this chapter, two transport networks are studied for UMTS access network: ATM (Asynchronous Transfer Mode) based transport network and IP based transport network with DSL (Digital Subscriber Line) technology. In the ATM based transport network, the authors suggest the traffic separation approaches by using separate ATM Virtual Paths (VPs) or Virtual Circuits (VCs) for transmitting R99 and HSPA traffic with different ATM QoS class. With the introduction of IP transport, the authors propose to transport the HSPA traffic over the DSL network while transmitting the R99 traffic with the legacy ATM network. The benefit of applying traffic separation and its impact on the performance of the transport network as well as the end users are studied in this article. The quantitative evaluations are provided by simulations. The results presented are obtained from own developed UMTS R99 and HSPA simulation models, which can generate HSDPA and HSUPA traffic as well as R99 traffic in the same UMTS network and transmit them with different transport technologies and traffic separation approaches. The presented results demonstrate that applying traffic separation between HSPA and R99 traffic can considerably improve the performance of both HSPA and R99 traffic, and as well bring significant gain on efficient bandwidth utilizations.
