摘　　要：移动性管理技术是实现异构网络融合的关键技术之一,而切换管理对移动性管理显得尤为重要。针对未来异构网络的特点,本文研究了相应的切换机制,并对不同方案进行了比较分析。结果表明,两种混合式方案具有较好的切换性能,极具应用潜力。Mobility management is one of the key technologies for convergence of heterogeneous networks, and handover management is especially critical to mobility management. Considering the characteristics of future heterogeneous networks, the paper studies relative handover mechanisms, compares and analyzes their performance respectively. The results shows that two hybrid mechanisms have better handover performance, and are deemed as potential schemes in the future.
