6 CONCLUSIONS
IMS through full IP is a good solution to provide
cross-platform integration service between different
regions on heterogeneous wired or wireless network.
However, in real-time transmission (e.g. VoIP), the
quality of data transferring may be affected by a
delay during network transmission. Service needs in
diverse applications flows should be considered
while transmitting signals over wired or wireless
network.
This paper proposes the QPF with different levels
of priority weights given as per diverse data type of
application service flows such as VoIP, VoD and
Web etc. We perform simulations with comparisons
on two KPIs of Delay and Throughput between QPF
and PF schemes, by using NS-2 software tool under
various multimedia application services, such as
VoIP, VoD and Web. The simulation results indicate
that QPF lowers 20% for VoIP delay and gains
8.19% more VoIP Throughput than PF. The QPF
performance for VoD delay can be enhanced by
11.53%, the Throughput is increased by 8.05%. Also,
the delay for Web of QPF can be improved by
28.58% and the Throughput is enhanced by 25.25%.
Consequently, the proposed QPF can provide better
services to corresponding flow levels upon different
applications over 3.5G network, which not only
improves the effectiveness and efficiency of
multimedia application services but also enhances the
QoS of overall network.
