QoS Mapping Approach for UMTS-WLAN Integrated Network

Future generation of heterogeneous wireless network is expected to provide multimedia, multi class applications any time anywhere with required degree of Quality of Service (QoS). However, every application has different QoS requirement in terms of acceptable packet loss, jitter, delay, throughput etc. Therefore, in such environment providing guaranteed end to end QoS along with seamless mobility is an important and challenging issue. To address this issue an appropriate QoS mapping is a primary and important requirement. In this paper, an end to end QoS mapping scheme between integrated UMTS and WLAN network has been proposed.
