技术领域

背景技术
小区间切换是指在通话期间，当移动终端从一个小区进入另一个小区时，网络能进行实时控制，把移动台从原小区所用的信道切换到新小区的某一信道，并保证通话不间断。小区间切换常用的切换方式通常是根据移动终端上报的邻区下行信号质量来选择，下行信号越好的邻区，越容易被作为优先切换目标。即便存在基于负荷或邻区优先级等邻区选择策略，也会在过滤结果集合中，优先选择下行质量好的邻区作为最终切换目标。但是，这种方式只能保证选择终端优先切换到下行干扰小的邻区，实际应用中，上行信号也会出现干扰(比如大气波导场景)，由于上行干扰的存在，也会影响通话品质，因此用户的体验度也明显降低。

本发明实施例目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
以下结合附图和实施例，对本发明实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明实施例，并不用于限定本发明实施例。
本发明实施例一提供了一种干扰处理的方法，应用于第一通信节点，请参阅图1，该方法包括：步骤S101、步骤S102和步骤S103。
在步骤S101中，确定小区的下行参考信号接收功率RSRP边界值。
在步骤S102中，接收用户设备UE上报的下行RSRP测量值。
在步骤S103中，当该下行RSRP测量值小于该下行RSRP边界值时，将该UE迁出该小区。
请参阅图2，为上行受扰小区的状态示意图。图2中小区覆盖范围部分是指该小区信号能够覆盖到的范围，如图2细线外圈所示。该小区为受扰小区，是由“正常区域”和“干扰区域”组成：
正常区域，如图2所示的填充图案部分。在该范围内小区状态基本可以认为弱干扰或无扰，可以保证正常的通话品质。实际应用中，离小区越近，路损越少，基站接收到的信号越好。因此，在有上行干扰时，终端离小区越远，干扰越明显。反之，干扰相对不明显。因此，正常区域是受扰小区的有效部分。
干扰区域，在如图2所示的小区覆盖范围内且填充图案部分之外的范围，是在受扰小区的正常区域和受扰小区边缘之间的区域，也是干扰比较强烈的区域，不建议移动用户接入，因为即便接入，用户感知度也很差，是受扰小区的无效部分。
实际应用中，当基站定时进行干扰检测、识别出受到上行干扰时，不仅进行基带抗扰处理，也通知受扰的小区其受到上行干扰，并告知其小区上行噪声干扰功率值(Noise interference，NI)。
当受扰的小区获知自己为上行受扰小区时，为了保证用户感知度，确认自己的正常区域和干扰区域，将干扰区域(此区域内用户体验差)内的UE及时通过切换方式迁出。同时，也可以与周围邻小区互动，保证邻区准备切换到本小区的UE能切入到本小区的正常区域。
实际应用中，正常区域的边界值可以设定为下行参考信号接收功率(Reference Signal Receiving Power，RSRP)边界值。
在一个可行的方案中，可以根据小区下行参考信号发射功率，用户设备(User Equipment，UE)的最大上行发射功率，噪声干扰功率，小区的接收天线数目，最小接收信干噪比，以及预置补偿参数确定小区的下行RSRP边界值。
在一个可行的方案中，该下行RSRP边界值包括语音业务的下行RSRP边界值和/或数据业务的下行RSRP边界值。
实际应用中，当下行RSRP边界值包括语音业务的下行RSRP边界值时，所述最小接收信干噪比为语音业务传输的最小接收信干噪比；或者
当下行RSRP边界值包括语音业务的下行RSRP边界值时所述最小接收信干噪比为数据业务传输的最小接收信干噪比。
实际应用中，根据SINR的计算公式：
SINR traffic＝Pcmax-(RS 功率-RSRP)-NI+10Log(AntNum)+IDP
可以推导出如下公式：
RSRP＝RS 功率–Pcmax+NI–10Log(AntNum)+SINR traffic-IDP。
其中，RS 功率为本小区下行参考信号发射功率，Pcmax为UE最大上行发射功率，NI为小区上行噪声干扰功率，AntNum为本小区接收天线数目，SINR traffic是不同业务(包括语音业务和数据业务)传输的最小接收信干噪比，IDP(Interference Default parameter)为受扰模型预置补偿参数。
上述公式中的RSRP即为正常区域的下行RSRP边界值，以此作为正常区域的边界值。
SINR traffic可以在后台进行配置，其是不同业务(包括语音业务和数据业务)传输的最小接收信干噪比。不同的业务所需的信道条件是不同的，例如语音业务需要较高的信道条件、数据业务在较差的信道条件下仍然可以满足用户的需求，因此在存在语音业务的情况下，需要区分为SINR traffic(语音)和SINR traffic(数据)等。
因此，当UE存在语音业务时，根据预设的公式RSRP 语音＝RS–Pcmax+NI–10Log(AntNum)+SINR traffic(语音)-IDP计算本小区的语音业务的下行RSRP边界值；
当UE无语音业务时，根据预设的公式RSRP 数据＝RS–Pcmax+NI–10Log(AntNum)+SINR traffic(数据)-IDP计算本小区的数据业务的下行RSRP边界值。
IDP是受扰模型预置补偿参数(比如大气波导干扰模型下的补偿参数，或是其他上行干扰模型的补偿参数)，其根据传输信道的模型以及基站处理的热噪声等因素进行补偿，可以通过后台配置。
其他参数，如NI可以由基站自测获取，RS功率和AntNum可以在后台配置。
实际应用中，获取UE的最大发射功率Pcmax的方式有两种，一种是从UE上报的基站内容中获得，此时获取的是每个UE的Pcmax，一种是用Pcmax预设值代替(这是因为大部分UE的Pcmax都是相同的)。
如果使用每个UE上报的Pcmax代入上述公式，算出来的是针对每个UE自己独有的下行RSRP边界值(数据)和下行RSRP边界值(语音)。
如果使用Pcmax预设值代入上述公式，算出来的是受扰小区的下行RSRP边界值(数据)和下行RSRP边界值(语音)。
基于上述公式，可以看出正常区域的边界除了和小区自身配置有关外，也可能因UE的不同而不同、因UE的业务类型的不同而不同、因干扰的类型和强度不同而不同。通常情况下，干扰越小或基站对干扰处理的越好，这个正常区域覆盖范围会越来越大；当干扰被消除或基站基带能够完全抗干扰处理，这个正常区域将和受扰小区的边缘重合，即受扰小区变为一个完全正常的小区。而在有干扰的情况下，正常区域也可以认为是本小区实际可用有效范围。
实际应用，执行步骤S102之前，该方法还包括：
获取该本小区的UE上报的本小区的下行RSRP测量值；
当该本小区的UE存在语音业务时，判断该下行RSRP测量值是否小于该RSRP 语音；
若是，确定该本小区的UE处于该正常区域边界之外；
当该本小区的UE无数据业务时，判断该下行RSRP测量值是否小于该RSRP数据；
若是，确定该本小区的UE处于该正常区域边界之外。
实际应用中，可以采用定时刷新的方式获取本小区内所有UE上报的下行RSRP测量值，并与下行RSRP边界值进行比较。
实际应用中，由于不同的业务所需的信道条件是不同的，例如语音业务需要较高的信道条件、数据业务在较差的信道条件下仍然可以满足用户的需求，因此在存在语音业务的情况下，需要区分为SINRtraf fic(语音)和SINR traffic(数 据)。
如果UE存在语音业务，则在UE的下行RSRP测量值>＝下行RSRP边界值(语音)时，认为UE在能保证语音质量的正常区域范围内，无需迁移；在UE的RSRP测量值<下行RSRP边界值(语音)时，认为UE在不能保证语音质量的干扰区域范围内，需要迁出处理。
如果UE不存在语音业务，则UE的RSRP测量值>＝下行RSRP边界值(数据)时，认为UE在能保证数据业务质量的正常区域范围内，无需迁移；在UE的RSRP测量值<下行RSRP边界值(数据)时，认为UE在不能保证数据业务质量的干扰区域范围内，需要迁出处理。
在一个可行的方案中，该方法还包括：
接收邻小区的受扰状态消息，确定所述邻小区的下行RSRP边界值；
当所述UE上报的邻小区的下行RSRP测量值大于或等于所述邻小区的下行RSRP边界值时，将所述邻小区作为所述UE的候选目标小区。
实际应用中，所述邻小区的受扰状态消息携带所述邻小区的下行RSRP边界值；或者
所述邻小区的受扰状态消息携带用于计算所述邻小区的下行RSRP边界值的参数。
实际应用中，当本小区接收到邻小区发送的受扰状态更新消息后，可以获取并更新触发该消息的邻小区的状态。
如果该邻小区最新状态是受扰态，其发送的受扰状态更新消息携带的参数可能分两种情况，此时，如果本小区准备决策对UE进行切换迁出，在候选切换目标小区中选择时，发现候选小区的标识为受扰小区，就需要根据携带的参数做出不同的处理，获取该受扰邻小区的下行RSRP边界值。
一、受扰状态更新消息携带的参数个数是2，则认为收到的是该受扰邻小区的下行RSRP边界值(数据)和下行RSRP边界值(语音)，保存在该受扰的邻小区标识下。
如果待迁出的UE存在语音业务，直接使用受扰的邻小区的下行RSRP边界值(语音)，如果待迁出的UE存在数据业务，直接使用受扰的邻小区的下行RSRP边界值(数据)。
二、受扰状态更新消息携带的参数个数是5，则认为携带的是正常区域的计算参数，保存在该受扰的邻小区标识下。
如果待迁出的UE存在语音业务，将计算参数代入前述公式计算出该受扰邻小区的下行RSRP边界值(语音)，其中，计算参数包括受扰的邻小区的RS 功率、NI、AntNum、SINR traffic(语音)以及待迁出的UE的Pcmax。
如果UE只存在数据业务，将计算参数代入前述公式计算出该受扰邻小区的下行RSRP边界值(语音)，其中，计算参数包括受扰的邻小区的RS 功率、NI、AntNum、SINR traffic(语音)以及待迁出的UE的Pcmax。
需要说明的是前述公式中的IDP参数可以从本小区的后台获取。
在一实施例中，判断待迁出的UE是否处于该邻小区的下行RSRP边界值之内包括：
获取待迁出的UE对该受扰邻小区的测量上报的RSRP测量值；
判断待迁出的UE的业务类型；
如果待迁出的UE存在语音业务，则：
在待迁出的UE上报的下行RSRP测量值>＝该受扰邻小区的下行RSRP边界值(语音)时，表明待迁出的UE已经在该邻小区正常区域(语音)的覆盖范围内，则可以继续作为后续切换目标小区。否则，表明待迁出的UE处在干扰区域中，该受干扰的邻小区不再作为候选目标小区。
例如可以如图3所示，如果待迁出的UE在邻小区的正常区域内，则将该邻小区继续作为后续切换目标小区，如果待迁出的UE在邻小区的干扰区域内，则受干扰的邻小区不再作为候选目标小区。
如果UE无语音业务，则：
在待迁出的UE上报的下行RSRP测量值>＝该受扰邻小区的下行RSRP边界值(数据)时，表明待迁出的UE已经在该受干扰的邻小区正常区域(数据)的覆盖范围内，则可以继续作为后续切换目标小区。否则，表明待迁出的UE处在干扰区域中，该受干扰的邻小区的不再作为候选目标小区。
在一个可行的方案中，该方法还包括：
向邻小区发送受扰状态消息，该受扰状态消息携带该小区的下行RSRP边界值，或用于计算该小区下行RSRP边界值的参数。
实际应用中，当本小区变为受扰状态时可以通过如下途径与邻小区进行互动：
1、通过基站间直接的消息(例如第四代移动通信技术(4Generation，4G)的X2，第五代移动通信技术(5fifth-generation，5G)的Xn)。
2、通过基站间经核心网传递的消息(例如4G的S1，5G的NG-C)。
当本小区从正常小区变为受干扰小区时，受扰状态更新消息可以携带如下两种信息。
1)受扰标识：表明本小区状态(比如，0为正常小区，1为受扰小区)。
2)携带参数的个数和内容：(可以采用如下的A和B两个方式中的任意一个)。
方式A、携带参数个数为2个；
携带参数内容：受扰小区下行RSRP边界值(语音业务)和下行RSRP边界值(数据业务)。
方式B、携带参数个数为5个；
携带参数内容：本小区的下行RS发射功率、本小区的接收天线数目AntNum、本小区的上行噪声干扰功率NI、本小区的最小接收信干噪比SINRtraffic(语音)及本小区的最小接收信干噪比SINRtraffic(数据)。
实际应用中，可以在本小区的受扰状态变化时，例如从正常小区变为受干扰小区，反之从受干扰小区变为正常小区时，也应当向各配置的邻小区发送受扰状态更新消息，使周围的邻小区收到受扰状态更新消息后重置本小区的状态为正常，并将本小区的干扰相关的参数置为无效参数。
实际应用中，当本小区接收到基站基带发送的上行干扰消失的通知时，本小区还可以执行如下操作：
1、更新自身状态为正常。
2、停止获取小区全部UE测量值的刷新过程，并清空计算正常区域计算相关参数，此时所有通信流程按基站在正常状态时的流程处理。
本实施例的干扰处理的方法，在获知本小区受到上行干扰时，通过计算本小区的下行RSRP边界值，确认自己的正常区域和干扰区域，将干扰区域(此区域内用户体验差)内的UE(该UE上报的下行RSRP测量值小于下行RSRP边界值)及时通过切换方式迁出，从而使UE能够避开本小区上行干扰的影响，不仅能够提高上行干扰下的切换成功率和用户感受度，并能够最大限度利用受扰小区的正常区域。
本发明实施例二提供了另一种干扰处理的方法，应用于第一通信节点，请参阅图4，该方法包括：步骤S1001和步骤S1002。
在步骤S1001中，确定小区的下行参考信号接收功率RSRP边界值。
在步骤S1002中，当待切入该小区的UE上报的该小区的下行RSRP测量值小于该下行RSRP边界值时，拒绝该UE的切换请求。
在一个可行的方案中，可以根据小区下行参考信号发射功率，UE的最大上行发射功率，噪声干扰功率，小区的接收天线数目，最小接收信干噪比，以及预置补偿参数确定小区的下行RSRP边界值。
实际应用中，可以采用实施例一的方法计算下行RSRP边界值，此处不在赘述。
在一个可行的方案中，执行步骤S202之前，该方法还包括：
从接收的切换请求消息中获取待切入的UE上报的本小区的下行RSRP测量值；
当该待切入的UE存在语音业务时，判断该下行RSRP测量值是否小于该RSRP 语音；
若是，确定该待切入的UE处于该正常区域边界之外；
当待切入的UE无语音业务时，判断该下行RSRP测量值是否小于该RSRP 数据；
若是，确定该待切入的UE处于该正常区域边界之外。
在有些场景中，当本小区被作为切换目标的目标小区可能直到切换时才发现自己是受上行干扰的小区，此时，需要在目标小区做判断，决定是否允许切入。
实际应用中，当待切入的UE的源小区发起切换时，可以在S1或X2的切换请求消息中携带待切换UE的Pcmax和待切换UE对该本小区的测量上报的下行RSRP测量值)。
本小区收到切换请求消息后，获取消息中全部参数，包括切换UE的Pcmax和下行RSRP测量值。
此时，本小区识别自己的受扰状态，如果为正常小区，可忽略切换请求消息中的切换UE的Pcmax和RSRP，按常规切换流程处理即可，如果为上行受扰小区：则需要计算本小区的正常区域边界，并识别待切入的UE的业务类型。
在计算本小区的正常区域边界时，需要获取的参数包括：本小区的RS 功率、待切换的UE的Pcmax、本小区的NI、本小区的AntNum、和本小区的SINR traffic。
实际应用中，对于SINR traffic，可以根据待切换的UE的业务类型分情况获 取：
如果待切换的UE是语音业务，则获取本受扰小区的最小接收信干噪比SINR traffic(语音)；如果待切换的UE是语音业务，则获取本受扰小区的最小接收信干噪比SINR traffic(数据)。
在决策时，如果待切换的UE存在语音业务，则：
当待切入的UE上报的下行RSRP测量值>＝本小区的下行RSRP边界值(语音)时，表明待切入的UE已经在本小区正常区域(语音)的覆盖范围内，则接纳本此切换，回复确认消息。否则，表明待切入的UE处在干扰区域中，则拒绝本此切换，回复拒绝消息。
如果待切入的UE无语音业务，则：
当待切入的UE上报的RSRP测量值>＝本小区的下行RSRP边界值(数据)时，表明待切入的UE已经在本小区正常区域(数据)的覆盖范围内，则接纳本此切换，回复确认消息。否则，表明待切入的UE处在干扰区域中，则拒绝本此切换，回复拒绝消息。
需要说明的是，实际应用中，源小区传递的切换请求消息中可以省略待切换的UE的Pcmax，因为大部分UE的Pcmax都相同，目标小区在计算下行RSRP边界值时，可以用Pcmax预置值代替。
在一个可行的方案中，当获知本小区为上行受扰小区时，所述方法还包括：
向邻小区发送受扰状态更新消息，所述受扰状态更新消息携带本小区的下行RSRP边界值，或本小区的下行RSRP边界值的计算参数。
实际应用中，可以采用实施例一的方法向邻小区发送受扰状态更新消息，此处不在赘述。
本实施例的干扰处理的方法，在获知本小区受到上行干扰时，通过计算本小区的下行RSRP边界值，确认自己的正常区域和干扰区域，拒绝处于该正常区域边界之外的待切入本小区的UE(该UE上报的下行RSRP测量值小于下行RSRP边界值)的切换请求，从而使UE能够避开本小区上行干扰的影响，不仅能够提高上行干扰下的切换成功率和用户感受度，并能够最大限度利用受扰小区的正常区域。
本发明实施例三提供了另一种干扰处理的方法，本实施例中，以基站1和基站2为例对干扰处理进行说明，其中基站1包括小区A和B，基站2包括小 区C和D；A小区包括UE-A1，UE-A2，B小区包括UE-B，C小区包括UE-C1、UE-C2；UE-A1仅有数据业务，UE-A2有语音业务，UE-C1为数据业务，UE-C2为语音业务；小区A、B、C、D全部互为邻区，并且彼此通过X2进行通信。本实施例中小区A、B、C、D已经互相通过X2交流过必要的邻区参数信息。假设大气波导干扰突然出现，基站1检测发现出现大气波导干扰，并进行抗干扰处理，同时，基站1的基带通知高层小区A和B存在大气波导干扰，并通知干扰NI值。
为方便描述，本实施例将不同的场景分开描述。
场景一、小区A接收到基带的通知，计算本小区的下行RSRP边界值，并决策本小区内的UE是否需要迁出。
该场景下，小区A可以通过两种方法实现计算本小区的下行RSRP边界值，并决策本小区内的UE是否需要迁出。
方法一请参阅图5，包括：步骤S401至步骤S406。
在步骤S401中，标识干扰状态为受扰，并记录NI值。
在步骤S402中，从后台获取本小区的RS 功率、AntNum、SINRtraffic(语音)、SINRtraffic(数据)及大气波导类型补偿参数Atmospheric Default Parameter。
在步骤S403中，开启定时器，定时遍历和扫描小区内所有UE(包括UE-A1和UE-A2)，根据每个UE的接入信息获取每个UE的Pcmax，并获取每个UE在本小区的下行RSRP测量值。
在步骤S404中，识别每个UE的业务类型。
在步骤S405中，根据每个UE的业务类计算每个UE在本小区的下行RSRP边界值。
在步骤S406中，将每个UE在本小区的下行RSRP测量值与其在本小区的下行RSRP边界值进行比较，并在下行RSRP测量值＜下行RSRP边界值时，确定需要将该UE迁出。
本场景中，当遍历到UE-A1时，根据其接入信息获取其Pcmax-A1，获取其在本小区的下行RSRP测量值RSRP-A1；然后识别出UE-A1业务类型为仅有数据业务，因此根据公式RSRP 数据＝RS 功率–Pcmax+NI–10Log(AntNum)+SINR traffic(数据)-IDP，计算UE-A1在本小区的下行RSRP边界值为R-A1(Data)；在将RSRP-A1和R-A1(Data)进行比较，仅当RSRP-A1<R-A1(Data)时，确定需要将UE-A1迁出。
当遍历到UE-A2时，根据其接入信息获取其Pcmax-A2，获取其在本小区的下行RSRP测量值RSRP-A2，并识别出UE-A2业务类型存在语音业务，根据公式RSRP 语音＝RS 功率–Pcmax+NI–10Log(AntNum)+SINR traffic(语音)-IDP计算出UE-A2的语音业务的下行RSRP边界值R-A2(Voice)，将RSRP-A2和R-A2(Voice)进行比较，仅当RSRP-A2<R-A2(Voice)时，确定需要将UE-A2迁出。
方法二请参阅图6，包括：步骤S501至步骤S507。
在步骤S501中，标识干扰状态为受扰，并记录NI值。
在步骤S502中，从后台取获本小区的RS功率、AntNum、SINRtraffic(语音)、SINRtraffic(数据)、Pcmax预设值和大气波导类型补偿参数Atmospheric Default Parameter。
在步骤S503中，计算本小区的语音业务和数据业务的下行RSRP边界值。
在一实施例中，语音业务的下行RSRP边界值R(Voice)＝RS–Pcmax+NI–10Log(AntNum)+SINR traffic(语音)-Atmospheric Default Parameter；
数据业务的下行RSRP边界值R(Data)＝RS–Pcmax+NI–10Log(AntNum)+SINR traffic(数据)-Atmospheric Default Parameter。
在步骤S504中，开启定时器，定时遍历和扫描小区内所有UE，获取每个UE在本小区的下行RSRP测量值。
在步骤S505中，识别每个UE的业务类型，当UE的业务类型仅为数据业务时，执行步骤S506，当UE的业务类型存在语音业务时，执行步骤S507。
在步骤S506中，将该UE的下行RSRP测量值与R(Data)进行对比，仅在下行RSRP测量值<R(Data)时，确定该UE需要迁出。
在步骤S507中，将该UE的下行RSRP测量值与R(Voice)进行对比，仅在下行RSRP测量值<R(Voice)时，确定该UE需要迁出。
本场景中，当遍历到UE-A1时，获取其在本小区的下行质量测量值RSRP-A1，识别出UE-A1业务类型为仅数据业务，用RSRP-A1和R(Data)比较，仅当RSRP-A1<R(Data)时，确认UE-A1需要迁出。
当遍历到UE-A2时，获取其在本小区的下行质量测量值RSRP-A2，识别出UE-A2业务类型存在语音业务用RSRP-A2和R(Voice)比较，仅当RSRP-A2<R(Voice)时，确认UE-A2需要迁出。
场景二、小区A向邻小区发送受扰状态更新消息(该场景下，小区A已经完 成自身受扰状态的更新，即场景一已经发生)。
小区A向邻小区发送的受扰状态更新消息可以携带受扰标识以及受扰相关的参数。而其携带参数的个数和内容采用两种方式：
方式一、传递用于计算下行RSRP边界值的参数，此时，后台将会配置受扰状态消息中传递下行RSRP边界值计算用的参数。
方法包括：步骤1、步骤2和步骤3。
步骤1、获取后台配置为受扰状态更新消息中传递正常区域计算参数。

步骤3、将受扰状态更新消息发送给邻区B,C，D。
此时邻小区收到小区A的受扰状态更新消息后，识别小区A的状态为受扰小区，获取该受扰状态更新消息携带的参数类型为：跟随5个计算参数，读取并存储计算参数到A小区标识下，计算参数包括：
小区A的状态：受扰；
小区A的干扰计算参数有4个；

方式二、直接传递下行RSRP边界值，后台将会配置受扰状态消息中传递下行RSRP边界值。
方法包括：步骤1、步骤2和步骤3。
步骤1、获取后台配置为受扰状态更新消息中传递正常区域计算值。
步骤2、填写X2受扰状态更新消息，消息内容包括：
状态：受扰；
参数类型：下行RSRP边界值；
下行RSRP边界值R(Data)和R(Voice)；
步骤3、小区A将消息发送给邻小区B、C、D。
邻小区收到小区A的受扰状态更新消息后，识别小区A的状态为受扰小区，获取该受扰状态更新消息携带的参数类型为：跟随2个下行RSRP边界值，读取并存储下行RSRP边界值到A小区标识下，计算参数包括：
小区A的状态：受扰；
小区A的下行RSRP边界值有2个；
小区A的下行RSRP边界值R(Voice)和R(Data)；
场景三、小区A的迁出决策(筛选候选切换目标小区)。
该场景下，小区A和B已经完成场景一中的自身受扰状态的更新，和场景二中对邻小区的受扰状态信息的更新，由于小区A、B、C、D互为邻区，因此均进行了对邻小区受扰状态信息的更新。小区B、C、D作为候选小区的优先级顺序为B、C、D。小区A中UE-A1被决策迁出。
请参阅图7，方法包括：步骤S601至步骤S607。
在步骤S601中，获取UE-A1对邻小区B、C、D的测量上报信息。
在步骤S602中，读取各邻小区标识下存储的受扰状态，发现小区B为受扰小区，小区C和D为正常小区。
在步骤S603中，查看小区B标识下存储的参数，当存储的参数为计算正常和区域边界值的计算参数时，执行步骤S604和步骤S605，当存储的参数为下行RSRP边界值时，执行步骤S606和S607。
在步骤S604中，用UE-A1(数据业务)的Pcmax-A1和保存的小区B的计算参数，计算出小区B关于UE-A1的下行RSRP边界值(数据)为R-B-A1(Data)。
在步骤S605中，将UE-A1对小区B的下行RSRP测量值RSRP-B-A1和R-B-A1(Data)比较，如果RSRP-B-A1<R-B-A1(Data),则把B从候选目标小区中剔除。
在步骤S606中，获取小区B标识下存储的下行RSRP边界值(数据)为R-B(Data)。
在步骤S607中，将UE-A1对小区B的下行RSRP测量值RSRP-B-A1和R-B(Data)比较，如果RSRP-B-A1<R-B，则把B从候选目标小区中剔除。
本场景中，如果将小区B从候选目标小区中提出，则按照常规切换判决流程在正常小区C、D中进行决策，否则，按照常规切换判决流程在小区B和正常小区C、D中进行决策。
场景四、小区C的UE-C1因移动原因，发起切换决策。
该场景下，小区C、D为正常小区，小区A、B为受扰小区，且小区A、B、C、D，已经完成场景一和场景二的自身受扰状态的更新和对邻小区的受扰状态信息的更新。
请参阅图8，方法流程包括：步骤S701至步骤S707。
在步骤S701中，获取UE-C1对邻小区A、B、D的测量上报信息，并记录下本UE对邻区A，B、D的测量值为RSRP-A-C1，RSRP-B-C1，RSRP-D-C1。
本步骤中，可根据确认UE-C1对邻小区A、B、D的测量上报信息确认邻小区A，B、D为候选切换目标小区，优先级为A，B、D。
在步骤S702中，读取每个邻小区标识下存储的受扰状态，发现小区A、B为受扰小区，小区D为正常小区。
在步骤S703中，查看受扰小区标识下存储的参数，当存储的参数为计算正常和区域边界值的计算参数时，执行步骤S704和步骤S705，当存储的参数为下行RSRP边界值时，执行步骤S706和步骤S707。
在步骤S704中，用UE-C1(数据业务)的Pcmax-C1和保存的受扰小区的计算参数，计算出受扰小区关于UE-C1的下行RSRP边界值(数据)为R-受扰小区-C1(Data)。
在步骤S705中，将UE-C1对受扰小区的下行RSRP测量值RSRP-受扰小区-C1和R-受扰小区-C1(Data)比较，如果RSRP-受扰小区-C1<R-受扰小区-C1(Data)，则把受扰从候选目标小区中剔除。
在步骤S706中，获取受扰小区标识下存储的下行RSRP边界值(数据)为R-受扰小区(Data)。
在步骤S707中，将UE-C1对受扰小区的下行RSRP测量值RSRP-受扰小区-C1和R-受扰小区(Data)比较，如果RSRP-受扰小区-C1<R-受扰小区(Data)，则把(Data)从候选目标小区中剔除。
以对小区A的决策为例。小区C发现A为受扰小区后，结合UE-C1的业务类型为数据类型，获取到小区A的R-A-C1(data)(即根据UE-C1的PCmax得出的小区A的数据下行RSRP边界值)或R-A(data)(即根据后台配置的PCmax 得出的小区A的数据下行RSRP边界值)，和RSRP-A-C1比较。当RSRP-A-C1<R-A-C1(data)时(采用UE的Pcmax计算)或当RSRP-A-C1<R-A(data)时(采用后台的Pcmax计算)将A从候选目标小区中剔除。
重复上述步骤判断是否剔除小区B。
经过上述步骤，候选目标小区集合可能是{A，B，D}或{A，D}或{B，D}或{D}，如果集合是{D}，则直接选择D为切换目标小区。如果集合不是{D}，则按照基站正常状态下的流程，进行下一步筛选，选出切换目标小区。
场景五、小区D决策是否接受其他小区发起的切换请求。
该场景下，小区D为正常状态小区，小区C已经决策UE-C1发起向小区D的切换。因为近期大气波导经常出现，小区C向下去D发起的切换请求消息中携带UE-C1的Pcmax-UEC1和UE-C1对小区D的下行测RSRP量值RSRP-D-C1，以防干扰的临时出现。
请参阅图9，方法流程包括：步骤S801至步骤S804。
在步骤S801中，收到本小区基站基带通知更新为受扰小区和UE-C1发起的切换请求。
在步骤S802中，获取本小区的下行RSRP边界值的计算参数和UE-C1的相关参数。
其中，下行RSRP边界值的计算参数，包括：本小区的RS 功率、AntNum、SINR traffic(数据)、NI值和大气波导类型补偿Atmospheric Default Parameter。
UE-C1的相关参数包括：UE-C1的Pcmax、业务类型为数据、UE-C1上报的下行RSRP测量值RSRP-D-C1。
在步骤S803中，计算出本小区针对UE-C1的下行RSRP边界值R-D-C1(Data)。
在步骤S804中，比较RSRP-D-C1和R-D-C1(Data)，如果RSRP-D-C1<R-D-C1(Data)则拒绝切换，如果RSRP-D-C1>＝R-D-C1(Data)则接受切换。
场景六、上行干扰消失，受扰小区更新自身干扰状态并通知邻小区。
该场景下，基站检测发现大气波导干扰已经消失，基站基带通知本站原大气波导干扰覆盖的所有小区，本场景中为小区A和小B，下面以小区A为例进行说明。
请参阅图10，方法流程包括：步骤S901至步骤S904。
在步骤S901中，接收基站基带发送的上行干扰消失消息。
在步骤S902中，更新干扰状态为正常并重置与下行RSRP边界值相关的计算参数无效。
在步骤S903中，填写X2受扰状态更新消息，消息内容包括：
状态：正常,
参数类型：无。
在步骤S904中，将受扰状态更新消息发送给邻小区B、C、D。
此时，邻小区B、C、D收到小区A的受扰状态更新消息后，识别小区A的状态为正常小区，更新小区状态，重置小区A所有的正常区域边界的计算参数无效。
