为了提高无线网络规划中传播模型校正方法的实用性,针对连续波测试传播模型校正方法所存在的低效率和低准确性等问题,提出了一种利用现网路测数据进行传播模型校正的方法.从理论上证明了路测信号可以替代连续波测试信号用于传播模型校正,通过增加路测次数和利用历史数据、邻区数据等方法增加了有效数据量,从而解决了路测终端采样速率低的问题,给出了路测数据的过滤方法以形成可用的采样数据,最后分析了使用路测数据所带来的误差.在中国移动的网络上实际测试证明所提出的方法是准确和有效的,可用于不同标准或制式的移动通信网络.
In order to improve the practicability of the propagation model correction method in wireless network planning, aiming at the problems of low efficiency and low accuracy of continuous wave test propagation model correction method, a method of using existing geodetic data to correct propagation model is proposed It is theoretically proved that the road test signal can replace the continuous wave test signal for propagation model calibration, and the effective data amount is increased by increasing the number of drive tests and using historical data and neighbor data to solve the problem that the terminal sampling rate Low, the road test data filtering method is given to form the available sampling data, and finally the error caused by using the drive test data is analyzed. The actual test on China Mobile’s network proves that the proposed method is accurate and effective , Can be used for different standards or standard mobile communication network.
