【摘要】 目前移动通信网络技术的发展、移动终端功能的增强和移动业务应用内容的丰富,催生了各种无线多媒体业务(如短信、彩信、彩铃、手机邮箱和手机游戏等),但这些业务是以图像和文字为主的静态内容。随着通信界3G时代的到来,更快的无线下载速度为移动终端用户提供视频点播、直播等多媒体视讯业务创造了条件,而移动流媒体系统提供了一种较佳的解决方案。本文根据流媒体相关规范,参照业界主流媒体解决方案,设计了上海移动流媒体系统的完整架构,并通过需求分析定义了各个MDSP、DLSC等子系统功能,对各个接口进行了阐述。基于上海移动用户发展的市场预测,按照GPRS/EDGE用户和TD-SCDMA用户模型,逐一分析计算流媒体系统的硬件需求、存储需求等,给出流媒体系统的实际组网图及相关硬件配置。本文的创新主要在于根据实际环境和需求提出上海移动流媒体系统的设计方案,并对方案进行了测试验证。目前,按本文设计出来的流媒体系统已经开发割接上线,并投入应用取得了一定的运营效果。
【Abstract】 With the development of communication network technology, mobile terminal and cell phone game, different wireless multimedia services such as SMS、MMS、CRBT、Mobile Email、Mobile games and so on are coming out. However, most of these services are based on static content as graphs and letters. In the coming 3G era, the higher wireless download speed makes the multimedia video communication available via mobile terminal. Furthermore, streaming system provides a superior solution.Based on the relevant criterion and the industry mainstream solution, the author designed the complete frame of shanghai mobile streaming system, made the definition of MDSP, DLSC sub-systems through demand analysis, and explicated the detailed instructions of each interface. According to the forecasting of shanghai mobile market share, the author calculated streaming system hardware demand and storage demand using the GPRS/EDGE and TD-SCDMA models. Also, the author listed the streaming system actual network chart and the relevant hardware configuration.This paper point out the design of shanghai mobile streaming system based on the actual environment demand.and now, this design has been tested successfully.Nowadays, it has been in process and achieved some operational effects.
