摘要
为了提高3G以及未来的移动通信系统中多媒体数据的传输率,文章提出了结合点对点(P2P)和增强型多媒体组播和广播业务(E-MBMS)技术的LTE环境下的多媒体资源分发(CPEMRD)方案。该方案结合了P2P的扩展能力和E-MBMS的可靠性、可管理性,构建了可管理的、能够承载电信级内容应用的多媒体资源分发平台。该方案缓解了终端接入数量受限以及带宽窄、通信不稳定的问题,实现了用户间点对点互动功能。
To increase multimedia data transmission in 3G and LTE networks, multimedia resource distribution (CPEMRD), which is the combination of peer-to-peer (P2P) and enhanced multimedia broadcast and multicast service (E-MBMS) is presented in this paper. In this solution, the scalability of peer-to-peer (P2P) can be achieved with the reliability and manageability of E-MBMS. The multimedia resource distribution platform is manageable and capable of carrying telecommunication-level content. This solution also allows P2P interaction between users and alleviates the problems of limited access capacity, narrow bandwidth, and unstable communications.
