Video streaming is one of the most popular applications in today's networks, ranging from communications to entertainment, it penetrates into every aspect of our lives. Service providers concern more and more about Quality of Experience perceived by end user. This paper proposes a new model to evaluate the end-to-end video quality in LTE networks. Specially, we focus on real time streaming video service that based on Real Time Streaming Protocol. This paper investigate the impact of RAN parameters, namely, SINR and the number of users, on the user's QoE. According to simulation results, a mapping model between these arguments and the video quality is given eventually. This assessment method will help mobile network operators to optimize RAN performance to satisfy users' video quality expectations.
