摘　　要：将MPLS技术应用到基于IP的无线接入网络是近年越来越受到关注的新课题。本文提出了一种基于MPLS的微移动方案,方案采用在基站进行缓冲的方法降低切换时的分组丢失。最后对方案的性能从算法所产生的网络开销、切换时延与分组丢失几个方面进行了分析和讨论,结果表明本方案适用于高速微蜂窝及微微蜂窝的移动通信环境,并能满足一般的数据及实时业务的需求。In this paper, a micro-mobility scheme in MPLS-based wireless access network is proposed. By means of buffering at BSs, the packet ross induced by handoff is reduced. The performance of this scheme is evaluated from three aspects -- network overhead, handoff delay and packet loss. It shows that the scheme is applicable to the general data applications and real-time service in mobile communication system with high moving speed and small cell size.
