Abstract
With the construction of Vo LTE networks and high-defi nition video telephony application
how to assess the quality of LTE video call becomes more important. This article introduces the Vo LTE video telephony related protocols and background knowledge
and studys the key factors and quality assessment method affecting the video call service. Then combines the signaling and decodes RTP / RTCP to develop video telephony service evaluation system. It will be used in China Mobile automatically drive test systems.
