ABSTRACT: The last decade we have witnessed an unprecedented development of telecommunication technologies. This
is not only due to devices capacity improvement, but also due to
network performance amelioration. Moreover, new technologies were proposed such
as UMTS (3G), giving users more
mobility and therefore more freedom. However, this resulted in a more demanding application, particularly for QoS provisioning. WIFI and UMTS 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. 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 of 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. 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 to UMTS air interface (Uu interface
