【摘要】：目前全球通讯领域飞速发展,移动通信技术正在从3G向4G转变,移动终端可使用的带宽将大幅提升。与此同时智能移动终端的出现及发展使以往只能在PC机上运行的应用可以安装到人们的手机、PAD等移动设备上,用户可以随时随地访问需要的网络资源。eMBMS多媒体广播多播业务(evolved Multimedia Broadcast Multicast Service)为通信运营商提供了大容量直播、点播视频服务平台。其可使用LTE网络高速带宽,在内容提供商与移动终端间建立一套可靠的视频服务通道,为用户提供高质量的视频服务。这将可能成为移动运营商新的服务突破口和利润增长点。本文主要以模拟周边网元的方式对eMBMS系统中的核心节点BM-SC进行性能测试。论文的主要工作包括：1)研究和阐述了eMBMS系统的架构,以及各功能实体的功能和作用；2)分析研究了BM-SC节点的业务流程,它与周围节点的接口特性。对BM-SC的重要技术如SYNC协议、FLUTE协议、FEC协议等做了细致分析,为测试的算法打下理论基础;3)在研究结果的基础上设计了eMBMS的测试方案,定义测试场景,准备测试文件。对关键测试点设计测试算法,并根据算法设计开发测试工具；4)根据测试场景进行性能测试,检查测试点是否达到性能要求。当出现不满足性能要求的情况时对问题进行分析,改进测试工具、细化测试条件,最终确定性能瓶颈。对修改后的BM-SC重新进行性能测试,直至达到性能要求。
[Abstract]:At present, the rapid development of global communication field, mobile communication technology is changing from 3G to 4G, and the bandwidth that mobile terminals can use will be greatly improved. At the same time, the emergence and development of intelligent mobile terminal can be used only on the PC machine, which can be installed on mobile devices such as people's mobile phones, PAD and other mobile devices. The network resource.EMBMS multimedia broadcast multicast service (evolved Multimedia Broadcast Multicast Service) provides a large capacity live broadcast and video service platform for the communication operators. It can use the high speed bandwidth of LTE network and establish a reliable video service channel between content providers and mobile terminals to provide high quality for users. This will probably become the new service breakthrough and profit growth point of the mobile operators. This paper mainly simulates the performance test of the core node BM-SC in the eMBMS system by simulating the peripheral network element. The main work of this paper is as follows: 1) the architecture of the eMBMS system, the function and the function of each functional entity are discussed and expounded. Use; 2) analysis and study the business process of BM-SC node, its interface characteristics with the surrounding nodes. The important technology of BM-SC, such as SYNC protocol, FLUTE protocol, FEC protocol and so on, is carefully analyzed, and the theoretical foundation for the test algorithm is laid. (3) based on the results of the research, the test scheme of eMBMS is designed, the test scene is defined, and the test file is prepared. Design test algorithms on key test points and design and develop test tools according to the algorithm; 4) test the performance according to the test scene to check the performance requirements. When the performance requirements are not satisfied, the problem is analyzed, the test tools are improved, the test conditions are finalized, and the performance bottleneck is finalized. After the modification, the modification is made. BM-SC performs performance tests until performance requirements are met.
