Due to the rapid development of Internet technology, the greater demand for multimedia services causes the traffic collisions increasing. 3rd Generation Partnership Project (3GPP) specified IP Multimedia Subsystem (IMS) for next generation network service. For the real-time multimedia service such as video streaming, it requires a large amount of bandwidth resource. Besides, the different ongoing media sessions may cause traffic collisions. In this paper, we propose a dynamic video streaming quality adaption method for IMS. The video quality will dynamic adjust according to the background traffic, reducing bandwidth congestion when overall network loading is high. The simulation results show that by adopting proposed video adaption method, the service quality and reliability can be maintained.
