While speech services in mobile communication
systems are investigated quite well, video telephony services are
relatively novel in this sector. Because of the market penetration
of camera equipped mobile phones the video telephony service
is expected to become a widely used service. In this paper an
introduction of the protocols used for video telephony in UMTS
is given. Concepts for the performance evaluation in terms of
video (PEVQ) and audio quality (PESQ) are presented and
utilized. Evaluations are performed by both live measurements
and network emulation. The results show that there is quite
potential for improvements related to video telephony in UMTS
in terms of video quality and channel setup time. Finally, an
improved radio bearer configuration is provided which aims at
a better integration of video telephony services into the UMTS
architecture.
