Building accurate radio frequency footprint models is an exercise often conducted to optimize the performance of mobile communication networks. Despite the large number of theoretical models, operators frequently utilize empirical radio frequency measurements taken through drive test activities. However, obtaining these measurements is an expensive activity which also, due to its discretized nature, does not cover the entire area of the network and generally produces incomplete radio frequency footprint models. A method to characterize the radio frequency footprint using network configuration and performance measurements automatically collected by the network is presented in this letter. Data from an operating commercial Long Term Evolution network has been used to validate the results of the proposed method.

基于移动性指标的射频足迹表征

建立准确的射频足迹模型是一项经常用于优化移动通信网络性能的练习。尽管有大量的理论模型，但运营商经常利用通过路测活动进行的经验射频测量。然而，获得这些测量是一项昂贵的活动，由于其离散性，它没有覆盖整个网络区域，并且通常会产生不完整的射频足迹模型。这封信中介绍了一种使用网络配置和网络自动收集的性能测量来表征射频足迹的方法。来自运行中的商业长期进化网络的数据已用于验证所提出方法的结果。
