Applying WIFI QoS Techniques to UMTS Networks

Abstract

<p class="MsoNormal"> <span lang="EN-US">The last decade </span><span lang="EN-US">we </span><span lang="EN-US">ha</span><span lang="EN-US">ve</span><span lang="EN-US"> witnessed an unprecedented development of telecommunication technologies. This is not only due to devices capacity improvement, but also</span><span lang="EN-US"> due</span><span lang="EN-US"> to network performance amelioration. Moreover, new technologies were proposed such as UMTS (<st1:chmetcnv tcsc="0" numbertype="1" negative="False" hasspace="False" sourcevalue="3" unitname="g" w:st="on">3G</st1:chmetcnv>), giving users more mobility and therefore more freedom. However, </span><span lang="EN">this resulted in a more demanding application</span><span lang="EN-US">, particularly for QoS provisioning. WIFI and UMTS </span><span lang="EN">are among these new telecommunication technologies. Although each one has its own QoS techniques, WIFI experiences a lack in QoS provisioning and UMTS should be further improved to guaranty QoS.</span><span lang="EN"> </span><span lang="EN">Our approach is simple. To be improved, each technology can benefit from QoS techniques of the other, of course, if this is possible. In this case, it’s clear that UMTS can take advantage </span><span lang="EN">of</span><span lang="EN"> WIFI QoS techniques, because UMTS uses physically a multitude of channels, using different bit rates and channel managements. While, WIFI uses a single channel with a single channel management, that is random access method. UMTS also uses a random access channel (PRACH channel), therefore we can apply WIFI QoS techniques to UMTS PRACH channel. </span><span lang="EN-US">In this study, we present WIFI and UMTS networks. We will focus on the air interface functioning of both networks to highlight similarities, then we propose two schemes inspired from WIFI QoS techniques to apply </span><span lang="EN-US">to</span><span lang="EN-US"> UMTS air interface (Uu interface</span><span lang="EN-US"><o:p></o:p></span> </p
