After analyzing the user mobility pattern, an adaptive mobile multicast algorithm based on the mobility pattern is proposed.
在分析用户移动模式的基础上，提出一种基于用户移动模式的自适应移动组播算法。
Mobile multicast is a research hotspot of mobile network, but most of mobile multicast schemes suffer from the long multicast disruption time and heavy protocol cost.
移动组播是移动互联网络技术的一个研究热点，但现有移动组播方案存在着组播中断时间长、协议开销大等问题。
However, because there are many challenges in designing routing protocols of mobile multicast, such as the issue of dealing with the multicast source handover, studying progress remains hesitant.
但是，由于设计移动组播路由协议时遇到诸多的困难，比如处理组播源的切换问题，研究工作进展非常缓慢。
