摘要

为了提高局部室内无线通信质量，家庭基站正逐步应用于各类室内无线通信场景。在密集部署femtocell场景中，当用户设备由宏小区层切换至femto层时，密集的femtocell信号会影响用户设备切换的准确性，增加用户设备切换开销和不必要切换概率。针对上述问题，在密集部署femtocell环境下针对切换提出一个femtocell分集理念，在提高切换准确性的同时，降低不必要切换次数，并在此基础上提出了一种缓存切换策略，以提高设备由宏小区层切换至femto层的效率，通过仿真对所提机制的性能进行了验证。

Abstract

To improve the quality of indoor wireless communication

the femtocell begins to be deployed in different indoor wireless communication scenarios.In the densely deployed femtocell network

when users handover from the macrocell to the femtocell

the multiple RSRP from different femtocell seriously affect the accuracy of the handover process.To solve above problems

the idea of femtocell cluster was proposed to improve the handover accuracy and reduce the unnecessary handover.In addition

a cache handover strategy was proposed to improve the efficiency of handover from macrocell to femtocell.Simulation results verify the proposed algorithms and strategies.
