采用本发明实施例技术方案，可以避免或弱化卫星链路和蜂窝无线网络组网的移动应用覆盖上存在的小区间干扰问题，对提高系统的吞吐量非常重要。
在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述

图2是本发明实施例中网络架构的示意图；
图3是本发明实施例中移动覆盖干扰控制流程图；
图4是本发明实施例中移动覆盖干扰控制装置的示意图。
本发明的实施方式
下文将结合附图对本发明的实施方式进行说明。需要说明的是，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
实施例1
本申请发明人针对卫星链路和蜂窝无线网络组网的移动覆盖应用场景下，控制移动站点小区间的干扰问题，提出可以通过接入网络节点上报GPS位置信息，通过每个接入网络节点的GPS位置信息，计算出每个节点之间的距离，通过距离信息控制每个节点的发射功率，即可以控制多个节点信号重叠时小区之间的干扰。
如图1所示，本实施例提供一种移动覆盖干扰控制方法，主要包括以下步骤：
步骤101，网络侧接收接入网络节点上报的GPS位置信息，根据每个接入网络节点上报的GPS位置信息计算出每个接入网络节点之间的距离；
步骤102，若任两个接入网络节点之间的距离小于或等于第一设定门限(也可称为最小距离门限)，则网络侧向这两个接入网络节点中的一个或两个下发调整发射功率命令，该调整发射功率命令用于指示接入网络节点调小发射功率。
相应地，接入网络节点收到调整发射功率命令后进行功率发射调整，即调整覆盖地理范围大小，减小信号重复覆盖区域。
其中，蜂窝系统接入网络节点包括获取GPS位置信息模块，可通过该模块实时获取GPS位置信息，并周期上报GPS位置信息到网络侧。
网络侧下发的调整发射功率命令中可携带功率调整值信息，接入网络节点按照该功率调整值信息调小发射功率即可。
还有一些方案中，任两个接入网络节点之间的距离小于或等于第一设定门限(也可称为最小距离门限)时，网络侧在这两个接入网络节点中，优先选择当前用户数目少的小区所属的接入网络节点，并向所选择的接入网络节点下发调整发射功率命令即可。
除了考虑第一设定门限外，任两个接入网络节点之间的距离大于第二设定门限时，网络侧则向这两个接入网络节点下发恢复发射功率命令，该恢复发射功率命令主要用于指示接入网络节点恢复默认发射功率。
当任两个接入网络节点之间的距离小于或等于第一设定门限，且其中一个或两个接入网络节点已经按照网络侧下的调整发射功率命令调小发射功率时，网络侧则需要计算两个接入网络节点的物理覆盖半径之和；这样，当所计算的物理覆盖半径之和小于或等于第三设定门限时，网络侧向两个接入网络节点中的一个或两个下发调整发射功率命令即可。其中，物理覆盖半径可由接入网络节点上报给网络侧。
另外，若所计算的物理覆盖半径之和大于第三设定门限，则网络侧不需要再下发调整发射功率命令。
实际应用中，上述第一、第二及第三设定门限的取值可以相同或不同。
下面说明本实施例的详细实现过程。
图2所示为实施本例方法的网络架构，其中，通过接入网络节点GPS模块、预设的接入网络节点间的最小距离门限值、以及接入网络节点发射功率调整值，通过精确GPS位置信息计算每个接入网络节点距离信息统计，动态调整接入网络几点发射功率，即调整接入网络节点物理覆盖范围，该过程如图3所示，主要包括以下步骤：
步骤201，接入网络开启卫星链路移动覆盖干扰控制干扰功能；
步骤202，接入网络节点A和接入网络节点B分别安装获取GPS位置信息模块，实时获取GPS位置信息；
步骤203，接入网络节点A、B周期上报GPS位置信息到网络操作控制平台(即网络侧)；
步骤204，网络操作控制平台接收到接入网络节点A、B的GPS位置信息后，计算出A和B节点之间的距离；
步骤205，网络操作控制平台检测计算出来的A和B节点间距离信息，如果发现A、B节点距离小于MinDistanceThresholdValue(预设的最小距离门限即为第一设定门限，默认值为500，默认值可以根据实际发射功率和信号覆盖地理范围进行调整，单位m)，则直接选择B节点作为功率调整目标；
要说明的是，虽然本例中选择B节点作为功率调整目标，也可以选择A节点作为功率调整目标，或者同时选择A、B节点作为功率调整目标。
步骤206，网络操作控制平台对检测出来的需要调整功率的B接入节点发送功率调整命令，功率调整大小为AdjustPowerValue(预设的功率调整值即为功率调整值信息，默认值为3，默认值可以根据实际发射功率进行调整，单位db)；
步骤207，当B接入网络节点接收到网络操作控制平台下发的功率调整命令后，按照命令指示调整发射功率；
该步骤中，调整后发射功率＝总的发射功率-AdjustPowerValue；
步骤208，接入网络开启卫星链路移动覆盖干扰控制干扰功能结束。
实施例2
如图4所示，本实施例提供一种移动覆盖干扰控制装置，主要包括如下单元：
第一单元41，设置为：接收接入网络节点上报的GPS位置信息，根据每个接入网络节点上报的GPS位置信息计算出每个接入网络节点之间的距离；
第二单元42，设置为：在任两个接入网络节点之间的距离小于或等于第一设定门限(也可以称为最小距离门限)时，向这两个接入网络节点中的一个或两个下发调整发射功率命令，该调整发射功率命令用于指示接入网络节点调小发射功率。
上述网络侧下发的调整发射功率命令中可以携带功率调整值信息。
还有一些可选方案中，第二单元42在任两个接入网络节点之间的距离小于或等于第一设定门限(可称为最小距离门限)时，可以在这两个接入网络 节点中，选择当前用户数目少的小区所属的接入网络节点，并向所选择的接入网络节点下发所述调整发射功率命令。
考虑到多个接入网络节点之间每两个接入网络节点之间的距离均小于或等于第一设定门限的情况，在上述装置的基础上，还可以包括第三单元，该单元在任两个接入网络节点之间的距离大于第二设定门限，则向两个接入网络节点下发恢复发射功率命令，该恢复发射功率命令用于指示接入网络节点恢复默认发射功率。
另外，上述装置还可以包括第四单元，主要在任两个接入网络节点之间的距离小于或等于第一设定门限(也可称为最小距离门限)，且其中一个或两个接入网络节点已经按照调整发射功率命令调小发射功率时，计算两个接入网络节点的物理覆盖半径之和，并且在所计算的物理覆盖半径之和小于或等于第三设定门限时，向两个接入网络节点中的一个或两个下发调整发射功率命令。而第四单元，在所计算的物理覆盖半径之和大于第三设定门限时，则可以不再下发调整发射功率命令。其中，物理覆盖半径可由接入网络节点上报给网络侧。
实际应用中，上述第一、第二及第三设定门限的取值可以相同或不同。

    第一单元，设置为：接收接入网络节点上报的全球定位系统GPS位置信息，根据每个接入网络节点上报的GPS位置信息计算出每个接入网络节点之间的距离；
    第二单元，设置为：在任两个接入网络节点之间的距离小于或等于第一设定门限时，向所述两个接入网络节点中的一个或两个下发调整发射功率命令，所述调整发射功率命令用于指示接入网络节点调小发射功率。
  8. 如权利要求7所述的装置，其中，
    所述网络侧下发的调整发射功率命令中携带功率调整值信息。
  9. 如权利要求7或8所述的装置，其中，所述第二单元是设置为：
    在任两个接入网络节点之间的距离小于或等于第一设定门限时，在所述两个接入网络节点中，选择当前用户数目少的小区所属的接入网络节点，并向所选择的接入网络节点下发所述调整发射功率命令。
  10. 如权利要求9所述的装置，还包括：
    第三单元，设置为：在任两个接入网络节点之间的距离大于第二设定门限，则向所述两个接入网络节点下发恢复发射功率命令，所述恢复发射功率命令用于指示接入网络节点恢复默认发射功率。
  11. 如权利要求10所述的装置，其中，还包括：
    第四单元，设置为：在任两个接入网络节点之间的距离小于或等于第一设定门限，且其中任一个或两个接入网络节点已经按照所述调整发射功率命令调小发射功率时，计算所述两个接入网络节点的物理覆盖半径之和并在所计算的物理覆盖半径之和小于或等于第三设定门限时，向所述两个接入网络节点中的一个或两个下发调整发射功率命令，所述调整发射功率命令用于指示接入网络节点调小发射功率。
  12. 如权利要求11所述的装置，其中，
    所述第四单元，还设置为：在所计算的物理覆盖半径之和大于第三设定门限时，则不再下发调整发射功率命令。
  13. 一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行权利要求1-6任一项的方法。
