移动流媒体业务融合系统及性能分析

在三网融合的背景下,为了向用户提供一致的用户体验,并提高网络效率,可以考虑将流媒体业务相关的平台进行融合。分析了2种实现移动流媒体业务融合的系统架构,将多种流媒体业务融入到统一的流媒体业务架构中。通过整合业务发现机制,向用户提供一致的流媒体业务发现方式。在终端方面,整合流媒体业务客户端,用户在接入不同的流媒体业务时,可以获得接近一致的业务体验。分别讨论了基于门户融合的流媒体业务融合系统(simple mobile streaming service convergence system,SMSC)和基于业务平台融合的流媒体业务融合系统(complexmobile streaming service convergence system,CMSC),分析了这2种流媒体业务融合系统各自的特点,并对这2种方案的性能进行建模分析。理论分析和仿真结果显示,CMSC系统具有更好的性能,能改善用户体验并提高网络的效率,从而SMSC系统则易于实现。

Service convergence system for mobile steaming and its performance analysis

In order to provide a consistent user experience, and improve the efficiency of the network, two converged systems for supporting mobile triple play service are proposed. One system based on portals convergence is the SMSC (Simple mobile streaming service convergence system), the other system based on service platforms convergence is the CMSC (complex mobile streaming service convergence system). The various steaming video services that have been provided by different networks are integrated into a uniform steaming video service by the above two systems. The service processes are designed to provide nearly consistent quality of experience. Finally, the models of these two systems are calculated and analyzed, and the results show that the performance improvement of CMSC over the SMSC.
