摘　　要：基于现有的将MPLS和微移动IP协议结合起来的研究成果,主要是HMPLS和MMPLS,分析它们存在的问题,提出了一种解决方案。该方案通过域内的LSP扩展,克服了现有MPLS和微移动IP结合方案的一些缺点,并同样支持快速切换和较低的信令开销,而且支持平滑切换。The integration of MPLS and traditional mobile IP has many limitations. In order to improve its performance, many researches on integrating MPLS into micro-mobility were carried out. Based on these researches, especially HMPLS and MMPLS, this paper analysed their problems and then proposed a solution. Through LSP extension within a domain, this scheme overcomes some defects of current schemes of micro-mobility integrated with MPLS,supports fast and smooth handover and has lower signalling overhead.
