QoS in UMTS Network and Improvement Voice over IP Performance
2014
IOSR Journal of Electronics and Communication Engineering
This study adopted a simulation based network performance analysis to investigate the effects of the application of different voice encoder schemes on QoS of VoIP system ,deployed with UMTS network Through different network simulation experiments using realistic network scenarios in OPNET environment, the results indicated that the choice of suitable voice encoder scheme with a small number of voice frame size per packet have a significant impact over VoIP traffic performance when deployed with
