一种多层网射线跟踪模型仿真算法研究和应用

Research and application of a simulation algorithm for multi-layer network ray tracing model

目前通信传统网络质量方案制定,常基于人工现场勘测及二维地图分析,存在室内测试协调困难、高度信息缺失、人工核查误差大诸多问题,导致现网质量评估精度低,从而造成有限的站点资源无法利用最大化。在通信数智化转型时期,基于此,文章提出基于一种多层网射线跟踪模型仿真算法,该方法利用高精度三维电子地图,对建筑物三维立体真实还原,基于多层网射线跟踪模型仿真结果,可分层渲染出楼宇信号强弱情况,在优化措施实施或规划站点落地前,便可精确预估方案可行性、准确性,避免反复性现场操作。

Currently, the formulation of traditional communication network quality scheme is often based on manual on-site survey and two-dimensional map analysis. There are many problems, such as difficulties in indoor test coordination, lack of high information, and large manual verification error, which lead to low accuracy of existing network quality evaluation, and thus the limited site resources cannot be maximized. In the transformation period of communication digital intelligence, based on this,this paper proposes a simulation algorithm of ray tracing model based on multi-layer network. This method uses high-precision three-dimensional electronic map to restore the three-dimensional reality of buildings. Based on the simulation results of ray tracing model of multi-layer network, the building signal strength can be revealed layer by layer. Before the implementation of optimization measures or the landing of planning stations, the feasibility and accuracy of the scheme can be accurately estimated,Avoid repetitive field operations.
