本申请要求于2022年6月24日提交的中国专利申请NO.202210733633.8的优先权，该中国专利申请的内容通过引用的方式整体合并于此。
本申请实施例涉及通信技术领域，特别涉及小区簇划分方法及装置、电子设备、计算机可读存储介质。
小区是移动通讯网络中的基础网络单元，在实际的网络部署中，为了满足用户的移动切换要求，每个小区与其周边小区之间往往存在相应的重叠覆盖区域，相邻小区之间存在一定的相关性。在移动通信网络优化中，若仅仅对单个小区进行调整优化，必然也会对其邻区产生一定的影响，从而使得无法对整网的优化效果进行评估，但是如果是对目标区域网络中的所有小区同时考虑进行优化，则毫无疑问会大大增加网络优化的复杂度。因此，在网络优化过程中将网络中的小区进行合理分簇，按簇为单位进行优化，既可以提高整网的综合优化性能，又可以大大降低优化的复杂度。
目前小区簇划分方式无法进行簇的自适应划分，导致按簇优化后，用户感知性能没有得到提升。

目前小区簇划分方式主要是根据小区的工参经纬度信息、干扰信息等，采用Kmeans聚类方法进行簇划分，但是，这种簇划分方式需要事先给出整网需要划分的簇个数，因此，无法对整网区域进行簇的自适应划分；并且，对于每个簇包含的小区数目也无法进行控制，可能存在某些簇的小区数目过大，导致簇的优化复杂度过高且不可控的问题出现；并且，仅使用经纬度信息或干扰信息进行簇的划分，而不考虑用户信息，可能导致按簇优化后用户感知性能没有得到提升。
第一方面，本申请提供一种小区簇划分方法，图1示出了本申请一个实施方式提供的小区簇划分方法的流程图，参照图1，所述小区簇划分方法包括如下步骤S100至S101。
步骤S100，对于任意一个第i轮计算对应的小区簇组，根据第i轮计算对应的小区簇组中的两个小区簇的参考信号接收功率(RSRP，
Reference Signal Received Power),计算第i轮计算对应的小区簇组的重叠覆盖度；i为大于或等于1的整数，第i轮计算对应的小区簇组包括任意两个第i轮计算对应的小区簇。
为描述方便，本申请的实施方式采用小区簇组进行描述，在实现过程中，可以不对小区簇进行分组。
在本申请实施方式中，每一个小区簇组均包括两个小区簇。在进行第1轮计算时，每一个小区簇包括一个小区，也就是说，将每一个小区初始化为一个小区簇。
在本申请实施方式中，由于每一轮计算，对应的小区簇组、小区簇可能做了更新，与上一轮计算对应的小区簇组、小区簇不同，因此，第i轮计算对应的小区簇组、小区簇是指第i-1轮计算中进行簇的合并后得到的。
在一些示例性实施例中，由于每一个小区簇组均包括两个小区簇，因此，第i轮计算对应的小区簇组的重叠覆盖度包括：第i轮计算对应的小区簇组中的两个小区簇之间的重叠覆盖度。
在一些示例性实施方式中，由于每一个小区簇组均包括两个小区簇，可以假设第i轮计算对应的小区簇组中的两个小区簇为第一小区簇和第二小区簇；那么，根据第i轮计算对应的小区簇组中的两个小区簇的RSRP，计算第i轮计算对应的小区簇组的重叠覆盖度包括：在第i轮计算对应的小区簇组中的两个小区簇的小区数量之和小于或等于小区数量门限的情况下，针对每一个小区组，根据小区组的两个小区的RSRP计算小区组的重叠覆盖度；所述小区组包括：第一小区簇中的任意一个小区，以及第二小区簇中的任意一个小区；小区组的重叠覆盖度包括：小区组内两个小区之间的重叠覆盖度；根据所有小区组的重叠覆盖度计算第i轮计算对应的小区簇组的重叠覆盖度。

在一些示例性实施例中，由于每一个小区组均包括两个小区，可以假设小区组内的两个小区为第一小区和第二小区；小区组内两个小区之间的重叠覆盖度为用户上报的第一小区(如，服务小区)在第二小区(如，邻区)的重叠覆盖度，或者为用户上报的第二小区在第一小区的重叠覆盖度，或者为用户上报的第一小区在第二小区的重叠覆盖度以及用户上报的第二小区在第一小区的重叠覆盖度之和除以小区数量(如，此处为两个小区，则小区数量为2)；那么，根据小区组内的两个小区的RSRP计算小区组的重叠覆盖度包括：根据用户上报的第一小区的RSRP和第二小区的RSRP计算第一小区在第二小区的重叠覆盖度，以及根据用户上报的第二小区的RSRP和第一小区的RSRP计算第二小区在第一小区的重叠覆盖度；确定小区组的重叠覆盖度为用户上报的第一小区在第二小区的重叠覆盖度以及用户上报的第二小区在第一小区的重叠覆盖度之和除以2。
在一些示例性实施例中，根据用户上报的第一小区的RSRP和第二小区的RSRP计算第一小区在第二小区的重叠覆盖度包括：确定第一小区在第二小区的重叠覆盖度为满足第一预设条件的样本数与满足第二预设条件的样本数的比值，如公式(1)所示；所述样本包括：同一个用户设备同一次上报的第一小区的RSRP和第二小区的RSRP。
Vi为第一小区，Vj为第二小区，e(Vi,Vj)为用户上报的第一小区在第二小区的重叠覆盖度，X1为满足第一预设条件的样本数，X2为满足第二预设条件的样本数。
所述第一预设条件包括：第一小区的RSRP大于或等于第一小区
覆盖门限，且第二小区的RSRP大于或等于第二小区覆盖门限，且第二小区的RSRP和第一小区的RSRP的差值大于或等于邻区重叠覆盖差值门限；所述第二预设条件包括：第一小区的RSRP大于或等于第一小区覆盖门限。
在一些示例性实施例中，根据第二小区的RSRP和第一小区的RSRP计算第二小区在第一小区的重叠覆盖度包括：确定第二小区在第一小区的重叠覆盖度为满足第三预设条件的样本数与满足第四预设条件的样本数的比值，如公式(2)所示；所述样本包括：同一个用户设备同一次上报的第一小区的RSRP和第二小区的RSRP。
Vi为第一小区，Vj为第二小区，e(Vj,Vi)为用户上报的第二小区在第一小区的重叠覆盖度，X3为满足第三预设条件的样本数，X4为满足第四预设条件的样本数。

步骤S101，在所有第i轮计算对应的小区簇组的重叠覆盖度小于或等于簇合并门限的情况下，输出所有小区簇。
在一些示例性实施例中，在至少一个第i轮计算对应的小区簇组的重叠覆盖度大于簇合并门限的情况下，该方法还包括：将重叠覆盖度最大的第i轮计算对应的小区簇组中的两个小区簇进行合并,得到第i+1轮计算对应的小区簇；对于任意一个第i+1轮计算对应的小区簇组，根据第i+1轮计算对应的小区簇组中的两个小区簇的参考信号接收功率，继续计算第i+1轮计算对应的小区簇组的重叠覆盖度。
第i+1轮计算对应的小区簇包括：将重叠覆盖度最大的第i轮计算对应的小区簇组中的两个小区簇进行合并后得到的小区簇，以及第i轮计算对应的小区簇中未进行合并的小区簇。
为了便于理解本申请的小区簇划分方法，下面列举一个示例性实施例进行说明，所列举的示例不用于限定本申请的保护范围。
实施例1
本实施例1描述对目标区域内的小区进行小区簇的划分，假设目标区域内的小区数量为100个，分别为小区1至小区100，图2为本申请的实施例1提供的小区簇划分方法的流程图，如图2所示，该小区簇划分方法包括如下步骤S1至S6。
