TD-SCDMA与TD-LTE切换策略的研究

摘要

As the test network deployment of the TD-LTE. Betwwen TD-SCDMA and TD-LTE tongether become inevitable tendency. This paper base on the handover strategy ,which about TD-SCDMA and TD-LTE network to analysis and research, Combined with the weight of the business operators for different, through the detailed theoretical analysis, the establishment of a new set of TD-SCDMA and TD-LTE system switching between plots in the process mechanism, according to get the size of the profit value network to realize preference which network's purpose and provide a new hanover method. MATLAB built network model, combining switching strategies on existing in reality scene is simulated.%　　随着TD-LTE实验网络的广泛部署，TD-LTE与TD-SCDMA网络共存已成为不可避免的趋势。本文在对TD-LTE与TD-SCDMA切换策略分析的基础上，对如今的两种不同网络的切换策略进行了分析和研究，结合运营商对于各业务的权重不同，通过详细的理论分析，建立了一套新的TD-SCDMA和TD-LTE系统间小区切换流程机制，根据得到的网络收益值的大小达到了实现优先选择哪个网络目的，并且用MATLAB搭建了网络模型，结合切换策略对现实中存在的场景进行了仿真验证。
