摘要: 针对传统动态单频网多播/广播(MBSFN)不能满足域管理需求的问题,提出一种简单易行的动态域操作算法。介绍增强型多媒体广播组播业务逻辑架构和MBSFN域管理部署选项,建模研究MBSFN域传输特性。根据域传输特性的仿真结果,明确动态MBSFN域管理需求,按照需求提出一种动态域操作算法,对算法中门限值选取进行分析。仿真结果证明了其可行性。

Abstract: To achieve the requirement of Single Frequency Network(SFN) area management that traditional operation algorithm of SFN area can not meet, E-MBMS logical architecture and deployment consideration are introduced and the characteristic of SFN area is studied by emulation. A novel and simple algorithm is proposed to meet the requirement, which is proved by emulation that the operation algorithm of SFN area of the traditional dynamic MBSFN is improved. How to select thresholds of algorithm is investigated. Its feasibility is demonstrated.

Key words: Evolved Multimedia Broadcast and Multicast Service(E-MBMS), dynamic area, Single Frequency Network(SFN)
