Abstract
Universal Mobile Telecommunication Systems
(UMTS) known as Third Generation (3G) mobile
phone systems using Wideband Code Division Multiple
Access (WCDMA) standard aim to provide a high
bit rate of services to enable a high quality of multimedia
communications. The 3G specification entity,
3GPP, has defined a reliable link layer protocol, Radio
Link Control (RLC), for hiding transmission errors
from upper layers. Due to the complexity of the protocol
and the a number of parameter configurations
available, there are many ways that can degrade a system
performance, such as incorrect parameters configuration,
buffer missmanagement, protocol stalling,
etc. MPEG-4 is widely used for video stream services
due to its good video quality at low bit rate. In this
paper, we have studied on the impacts of RLC parameters,
especially RLC timer and polling mechanism,
for MPEG-4 video stream transmission by using a
computer simulation. Our simulation results provide
some suggestions value to optimize such parameters,
e.g. RLC time and polling. |
