摘　　要：小蜂窝网络是由比传统宏蜂窝基站发射功率更小的低功率节点形成的多层蜂窝网络。作为LTE-Advanced技术研究的重要内容之一,小蜂窝的发展越来越受到业界的关注。分析评估了移动性管理中多种移动状态估计(MSE)方案的性能指标,同时分析评估了蜂窝切换中所涉及的切换指令的保护方案性能以及蜂窝切换方案性能,最后对小蜂窝网络移动性管理面临的挑战和未来的研究方向做出总结。Small cell network is a muhi-layer cell network formed by low-power nodes whose base stations transmit power is lower than conventional macrocell base stations. More and more industry attention is pained to the development of small cell which is considered as an important part of LTE-Advanced technology study. The performance of a variety of mobile state estimation scheme in mobility management was analyzed and evaluated and the same work was done on the protection scheme of the switching instruction involved in a cellular switch. A summary was made about challenge and future research directions of small cell mobility management finally.
