在图5所示实施例的基础上，下面，通过图6所示的实施例，对本申请所示的覆盖调整方法进行说明。
图6为本申请实施例提供的另一种覆盖调整方法的流程示意图。请参见图6，该方法可以包括：
S601、终端设备对小区进行测量得到测量信息。
可选的，该终端设备可以为第一网络设备覆盖范围内的任意终端设备。
需要说明的是，S601中所示的小区和测量信息可以参见S501中的相关介绍，此处不再进行赘述。
S602、终端设备向第一网络设备发送测量信息。
可选的，当终端设备为空闲态或者去激活态时，终端设备可以通过日志方式记录测量信息并向第一网络设备发送测量信息。例如，可以以最小化路侧(minimization of drive-tests，MDT)的方式记录测量信息，并当终端设备由空闲态或者去激活态转为连接态时向第一网络设备发送测量信息。

S603、第一网络设备根据测量信息确定覆盖检测结果。
可选的，第一网络设备可以根据RRM信息和位置信息确定覆盖检测结果。
可选的，覆盖检测结果包括弱覆盖、越区覆盖或上下行传输不平衡中的至少一种。
弱覆盖是指一个区域中没有无线网络覆盖或者覆盖信号质量过差，可以将若覆盖的区域称为弱覆盖区域。弱覆盖包括小区间的弱覆盖和小区内的弱覆盖。弱覆盖区域的下行信号不稳定，导致弱覆盖区域内的终端设备的通信质量差，例如，弱覆盖区域内的终端设备容易发生掉话故障。
可选的，可以根据终端设备检测到的信号强度和/或信号质量，判断终端设备当前所在 的区域是否为弱覆盖。即，根据终端设备检测到的信号强度和/或信号质量，判断终端设备当前所在的数据点是否为弱覆盖数据点。例如，当终端设备检测到的信号强度或信号质量中的任意一个不满足对应的条件时，则确定终端设备当前所在的位置为弱覆盖。信号强度和/或信号质量可以为小区粒度的，也可以为波束粒度的。信号强度可以包括RSRP，信号质量可以包括RSRQ和SINR。
例如，当终端设备位于小区的中心位置(非边缘区域)时，可以根据终端设备检测到的该小区的信号强度和/或信号质量，判断终端设备当前所在的区域是否为弱覆盖区域。当终端设备检测到该小区的信号强度不满足条件1，和/或检测到该小区的信号质量不满足条件2，则确定终端设备当前所在区域为若覆盖区域，即，终端设备当前所在的数据点为弱覆盖数据点。
例如，当终端设备位于小区的边缘区域时，可以根据终端设备检测到的该小区的信号强度和/或信号质量，以及终端设备检测到的该小区的邻小区的信号强度和/或信号质量，判断终端设备当前所在的区域是否为弱覆盖区域。当如下四个条件中的一个被满足时，则确定终端设备当前所在区域为若覆盖区域，即，终端设备当前所在的数据点为弱覆盖数据点，该四个条件分别为：终端设备检测到该小区的信号强度不满足条件1、终端设备检测到该小区的信号质量不满足条件2、终端设备检测到该小区的邻小区的信号强度不满足条件3、终端设备检测到该小区的邻小区的信号质量不满足条件4。
越区覆盖是指网络设备的覆盖区域超过了规划的范围，在其它网络设备的覆盖区域内形成了不连续的主导覆盖区域。下面，结合图7对越区覆盖进行说明。
图7为本申请实施例提供的越区覆盖示意图。请参见图7，基站1的覆盖区域为小区D，小区A、小区B和小区C为除基站1之外的其它基站下的小区，由于基站1下的小区D对应的覆盖区域超出了基站1的规划范围，且小区D为在其它基站下的小区C中形成了覆盖区域，因此，小区D为越区覆盖。在该种情况下，当终端设备位于小区D时，由于小区D周围没有配置的双邻小区，因此，当终端设备从小区D移动至小区C时，则终端设备会发生掉话。而且即使为小区D配置了邻小区，由于小区D的区域较小，也容易出现终端设备来不及切换而发生掉话的问题。
可选的，可以根据终端设备测量得到的TA判断终端设备当前所在的位置是否为越区。例如，当终端设备测量得到的TA大于预设的TA阈值时，则确定终端设备当前所在的位置为越区。
上下行传输不平衡是指在一个覆盖区域内，上下行对称业务出现上行覆盖和下行覆盖质量不一致的情况。上下行对称业务是指对上行覆盖和下行覆盖要求一致的业务。上行覆盖和下行覆盖质量不一致的情况包括：下行覆盖良好且上行覆盖受限，以及上行覆盖良好且下行覆盖受限。其中，下行覆盖良好且上行覆盖受限的表现为终端设备的发射功率达到最大仍不能满足上行BLER要求。上行覆盖良好且下行覆盖受限的表现为下行专用信号码发射功率达到最大仍不能满足下行BLER要求。下面，结合图8，对上下行传输不平衡进行说明。
图8为本申请实施例提供的上下行传输不平衡示意图。请参见图8，下行覆盖区域较大，上行覆盖区域较小，即，下行覆盖良好且上行覆盖受限。例如，当终端设备位于区域A时，终端设备可以接收到良好的下行信号，但终端设备无法良好的发射上行信号。
可选的，可以通过终端设备测量的PHR和网络设备的期望接收功率来判断终端设备所处的区域是否出现上下行传输不平衡。例如，当终端设备测量的PHR达到最大，但是网络设备的期望接收功率仍小于预设功率，则确定终端设备所处的区域出现上下行传输不平衡。
可选的，对于上下行不平衡的小区，所述小区所属的第一网络设备可以通过给该小区下的UE配置小区重选参数来避免由于上下行不平衡带来的接入失败，其中所述小区重选参数可以包括面向特定小区的参数(例如R准则中的目标小区的偏移值Qoffset)，即所述第一网络设备修改对特定小区的Qoffset，并发送所述Qoffset给所述第一网络设备下的UE。示例性的，该Qoffset可以是小区粒度的，或者也可以是波束粒度的，也即第一网络设备发送给UE的小区重选参数可以包括小区标识、波束标识、频点标识、小区对应的Qoffset、波束对应的Qoffset中的至少一种。
S604、第一网络设备根据覆盖检测结果确定波束覆盖调整参数。
可选的，第一网络设备可以根据覆盖检测结果和测量信息确定波束覆盖调整参数。

需要说明的是，S604中的波束覆盖调整参数可以参见S502中关于波束覆盖调整参数的描述，此处不再进行赘述。
S605、第一网络设备根据波束覆盖调整参数，调整第一网络设备的小区覆盖和/或波束覆盖。
可选的，第一网络设备可以根据天线阵子的状态对天线阵子的状态进行调节，根据天线的相位差对天线的相位差进行调节，根据预编码矩阵对天线的预编码矩阵进行调节，进而实现调整第一网络设备的小区覆盖和/或波束覆盖。
可选的，在图6所示的实施例中，第一网络设备在接收到测量信息之后，可以向集中管理节点发送测量信息，由集中管理节点根据测量信息调整第一网络设备的小区覆盖和/或波束覆盖。例如，集中管理节点可以先根据测量信息确定覆盖检测结果，根据覆盖检测结果确定波束覆盖调整参数，并根据波束覆盖调整参数调整第一网络设备的小区覆盖和/或波束覆盖。或者，第一网络设备在确定得到覆盖检测结果之后，可以向集中管理节点发送覆盖检测结果，由集中管理节点根据覆盖检测结果调整第一网络设备的小区覆盖和/或波束覆盖。例如集中管理节点可以根据覆盖检测结果确定波束覆盖调整参数，并根据波束覆盖调整参数调整第一网络设备的小区覆盖和/或波束覆盖。例如，集中管理节点可以为OAM实体。
在图6所示的实施例中，在第一网络设备获取得到终端设备对小区进行测量的测量信息之后，可以根据测量信息确定第一网络设备覆盖范围内各位置上的覆盖情况，进而使得第一网络设备可以根据第一网络设备覆盖范围内各位置上的覆盖情况准确的确定得到覆盖检测结果，并根据覆盖检测结果对第一网络设备的小区覆盖和/或波束覆盖进行准确的调整，使得对覆盖调整的精准度更高，进而提高了网络覆盖调整的精准性。
