具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
为了便于理解本公开实施例提供的技术方案，下面先对蜂窝网络信号测量技术进行介绍说明：
路测是指通过在设定线路上进行蜂窝网络的信号质量测量，从而对蜂窝网络性能指标起到直接的测量评估作用的工作。路测能够指出蜂窝网络的问题所 在，使得运营商能够针对蜂窝网络的问题对网络进行优化。MDT是目前常用的一种路测技术，主要是通过用户的手机来测量并上报网络优化所需要的相关参数。但是，传统的MDT方案只针对地面通信，无法对空中的网络质量进行检测，不能帮助运营商准确发现并解决空中的网络问题。其中，蜂窝网络包括但不限于全球移动通信系统(GSM)网络、码分多址(CDMA)网络、频分多址(FDMA)网络、时分多址(TDMA)网络、第三代移动通信技术(3G)网络、第四代移动通信技术(4G)网络、第五代移动通信技术(5G)网络等。
为了实现对空中网络质量进行检测，可以将MDT与无人驾驶飞机(简称“无人机”(Unmanned Aerial Vehicle，UAV))进行结合，即利用具有蜂窝网络通信功能的无人机进行蜂窝网络信号测量，以弥补传统MDT方案的不足。
图1是本公开实施例提供的一种利用无人机进行蜂窝网络测量的示意图，参见图1，无人机10为具有蜂窝网络通信功能的蜂窝网络无人机，无人机10能够与基站20无线连接并进行通信，在与基站20进行通信的过程中，无人机10能够进行网络质量检测，并将检测结果上报给基站20，使得基站20可以根据该检测结果进行网络优化。
其中，无人机10是利用无线电遥控设备和自备的程序控制装置操纵的不载人飞行器，该无人机10可以是无人固定翼机、无人垂直起降机、无人飞艇、无人直升机、无人多旋翼飞行器或无人伞翼机等。
在目前的基站设计中，每个基站20都对应一个覆盖范围，目前基站20的覆盖范围主要是指天线主瓣21的覆盖范围，而天线主瓣21的覆盖范围主要是地面区域，如图1中区域M(虚线所示)。而服务无人机10的主要是天线旁瓣22，所以可能存在无人机处于一个基站20的覆盖范围内，但却是由相邻基站20的天线旁瓣22来服务该无人机10的情况出现，如图1，无人机10处于基站B的覆盖范围，然而服务该无人机10的是基站A的天线旁瓣22。
由于上述情况的存在，虽然在进行蜂窝网络信号测量时，无人机的飞行线路是按照基站覆盖范围设计的，但由于服务无人机的主要是天线旁瓣，所以会出现在一个基站的覆盖范围内接入到不同基站的情况，进而导致无人机将不同基站的网络质量数据当作同一个基站的网络质量数据上传给基站，进而影响基站的网络优化。
为了解决现有无人机进行蜂窝网络测量过程中存在的问题，本公开实施例提供了一种蜂窝网络信号测量方法、装置及计算机可读存储介质，详见后文实 施例。
图2是根据一示例性实施例示出的一种蜂窝网络信号测量方法的流程图，应用于无人机，该方法可以由无人机中的蜂窝网络信号测量装置执行，参见图2，所述蜂窝网络信号测量方法包括：
在步骤S11中，获取在所述无人机飞行过程中采集到的至少一组测量数据。
