Abstract

Nowadays users have a multitude of ways to connect with other users or applications servers to send and receive data. One of the most used is WIFI and UMTS (3G) networks. These technologies must satisfy users´ requirements especially those related to real time applications such as IP telephony or video streaming. Therefore WIFI and UMTS must implement QoS techniques to reach this satisfaction. Both networks handle differently QoS, particularly in the air interface, where WIFI has its own mechanisms while UMTS has no mature techniques. 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 improve QoS in UMTS air interface (Uu interface).
