摘　　要：首先分析了移动流媒体服务器系统的整体架构,对其中主控服务器、流服务器、流媒体代理服务器、移动数据网关、无线流媒体终端等模块在移动流媒体服务器系统中所扮演的角色进行了简略阐述;然后详细分析了其中需要解决的关键技术,例如移动流媒体传输的QoS保证、移动流媒体传输控制会话协议、移动流媒体代理服务器、移动流媒体服务器存储调度策略等,并对每项关键技术进行了深入研究,从而对移动流媒体服务器系统在3G移动网络上亟须解决的关键技术有比较深入的了解。The paper firstly analyzes the total architecture of mobile streaming media server system, including such modules as main controlling server, streamin g media server, streaming media proxy server, mobile streaming media gateway, wi reless streaming media terminal etc., and briefly describes the role played by s uch modules in the mobile streaming media server system. Then, key technologies that need to be resolved are analyzed in detail, such as the guarantee of QoS in mobile steaming media transmission, mobile steaming media transmission control session protocol, mobile streaming media proxy server, mobile streaming media se rver assigned storage strategy etc., and each of the key parts are studied in de pth so as to understand the key technologies of streaming media server system th at need to be urgently resolved for its application in 3G mobile network.
