Description

失步确定方法及装置
本申请要求于2017年3月17日提交中国专利局、申请号为201710162072.X、申请名称为“失步确定方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术，尤其涉及一种失步确定方法及装置。
背景技术
时分双工(Time Division Duplex；TDD)系统是严格时钟同步的系统，第三代合作伙伴计划(3rd Generation Partnership Project；3GPP)TS 36.133对TDD系统同步技术提出了严格的技术指标要求，要求宏蜂窝TDD系统各小区同步精度小于3us。如果某个基站时钟失步，该失步基站的下行符号就可能会干扰到其它同步基站的上行符号，同步基站的下行符号也可能会干扰到失步基站的上行符号，这样，会造成严重的上行同频干扰，导致网络终端无法入网，或者业务很差，如容易引起掉话、切换失败、无法做业务等，直接影响网络用户感受。
现有技术中，若基站中的时钟参考源丢失，通常会有相应的告警提示，并且基站会做相应的重新同步或者复位操作，并且时钟参考源丢失的时间超过预设的时间段之后，基站将会自动闭塞载扇，以防止基站对其他相邻同频小区造成干扰。
然而，若时钟参考源正常，但由于软件缺陷或者后端器件失效而导致基站时钟失步时，此时将无法发现失步的基站，从而导致确定失步的误差较大。
发明内容
本申请实施例提供一种失步确定方法及装置，用于解决确定基站时钟失步时的误差较大的问题。
第一方面，本申请实施例提供一种失步确定方法，包括：
控制网元接收N个基站发送的干扰指标；其中，干扰指标包括第一干扰与噪声、第二干扰与噪声和第三干扰与噪声，该第一干扰与噪声、该第二干扰与噪声和该第三干扰与噪声分别是上行子帧不同符号受到的干扰；
该控制网元基于该干扰指标从该N个基站和/或该N个基站的邻站中确定M个第一待检基站；
该控制网元确定P个第二待检基站；该P个第二待检基站为从该M个第一待检基站中选择出的满足检测条件的基站，该检测条件为该第一待检基站在无线帧的指定位置广播的特征序列均不能被邻站在该指定位置接收；
该控制网元从该P个第二待检基站中确定失步的基站；
其中，N和M为正整数，P为整数，P小于或等于M。
上述第一方面提供的失步确定方法，通过接收N个基站发送的干扰指标，并根据干扰指标，从N个基站和/或N个基站的邻站中确定M个第一待检基站，并确定P个第二待检基站，其中，P个第二待检基站为从M个第一待检基站中选择出的满足检测条件的基站，其中，检测条件为第一待检基站在无线帧的指定位置广播的特征序列均不能被邻站在指定位置接收，再从P个第二待检基站中确定失步的基站。由于控制网元根据基站上报的干扰指标先选择出M个第一待检基站，再根据邻站是否能够在无线帧的指定位置接收到第一待检基站在该无线帧的指定位置发送的特征序列，来选择出满足检测条件的第二待检基站，最终确定出失步的基站，由于通过不同的方式逐步缩小失步的基站确定的范围，从而可以提高失步确定的准确性。
在一种可能的设计中，该控制网元确定P个第二待检基站，包括：
该控制网元分别向该M个第一待检基站发送第一通知消息，该第一通知消息用于指示第一待检基站在该无线帧的预设位置上广播该特征序列；
该控制网元向各第一待检基站的邻站发送第二通知消息，该第二通知消息用于指示第一待检基站的邻站在该无线帧的预设位置上接收该特征序列；
该控制网元分别接收各第一待检基站的邻站发送的第一响应消息，该第一响应消息用于指示第一待检基站的邻站是否接收到该特征序列；
若该控制网元根据该第一响应消息，确定出该第一待检基站的所有邻站均未接收到该特征序列，则将该第一待检基站确定为该第二待检基站。
在上述可能的设计中，由于各第一待检基站分别在不同的无线帧的预设位置上发送特征序列，控制网元将判断每个第一待检基站的所有邻站是否在对应的无线帧的预设位置上接收到该特征序列，若第一待检基站时钟失步，则第一待检基站的邻站可能会因为错过接收检测窗，导致无法检测到特征序列，由此可以确定出可能失步的第二待检基站，从而使得第二待检基站的确定更加准确。
在一种可能的设计中，该控制网元确定P个第二待检基站，包括：
该控制网元分别向该M个第一待检基站发送第一检测消息，该第一检测消息用于指示第一待检基站在无线帧的预设位置上发送特征序列；
该控制网元分别接收该M个第一待检基站发送的第一反馈消息，该第一反馈消息中包括该第一待检基站确定出的各第二待检基站的标识信息；
该控制网元根据该标识信息确定该第二待检基站。
在上述可能的设计中，由于各第一待检基站分别在不同的无线帧的预设位置上发送特征序列，并判断所有邻站是否在对应的无线帧的预设位置上接收到特征序列，由此确定自身是否为第二待检基站，再将判断出的结果发送给控制网元，由此可以提高第二待检基站确定的效率。
在一种可能的设计中，该控制网元从P个第二待检基站中确定失步的基站，包括：
控制网元依次向P个第二待检基站发送第三通知消息，并向第二待检基站的邻站发送第四通知消息，其中，控制网元在接收到第i个第二待检基站的邻站发送的第二响应消息之后，向第i+1个第二待检基站发送第三通知消息，并向第i+1个第二待检基站的邻站发送第四通知消息，该第三通知消息用于指示第二待检基站在预设无线帧 上处于静默状态，该第四通知消息用于指示该邻站在该第二待检基站处于静默状态时进行干扰检测，第二响应消息用于指示在该第二待检基站处于静默状态时，第二待检基站的邻站检测自身受到的干扰是否发生变化；
该控制网元根据该第二响应消息，确定失步的基站。
在一种可能的设计中，该控制网元根据该第二响应消息，确定失步的基站，包括：
若该控制网元根据该第二响应消息，确定出该第二待检基站在预设无线帧上处于静默状态时，第二待检基站的邻站在该预设无线帧上检测到的干扰发生变化，则将该第二待检基站确定为该失步的基站。
在上述可能的设计中，由于第二待检基站在预设无线帧上执行下行静默后，邻站将在该预设无线帧上进行干扰检测，从而判断在第二待检基站处于静默状态时，自身所受的干扰是否发生变化，若控制网元判断出第二待检基站的邻站在该预设无线帧上所受的干扰发生了变化，并且变化规律符合第二待检基站的静默图谱，则可以确定出该第二待检基站为失步的基站，从而可以提高失步确定的准确性。

该控制网元依次向P个第二待检基站发送第二检测消息，其中，控制网元在接收到第i个第二待检基站发送的第二反馈消息之后，向第i+1个第二待检基站发送第二检测消息，该第二检测消息用于指示第二待检基站在预设无线帧上处于静默状态，该第二反馈消息中包括该第二待检基站确定出的失步的基站的标识信息；
该控制网元根据该标识信息确定该失步的基站。
在上述可能的设计中，由于第二待检基站在预设无线帧上执行下行静默后，邻站将在该预设无线帧上进行干扰检测，从而判断在第二待检基站处于静默状态时，自身所受的干扰是否发生变化，若第二待检基站判断出其的邻站在该预设无线帧上所受的干扰发生了变化，则可以确定其自身为失步的基站，并将判断结果发送给控制网元，以使控制网元对失步的基站执行自愈操作，由此可以提高失步确定的效率。

若该N个基站的该第一干扰与噪声、该第二干扰与噪声和该第三干扰与噪声均大于该预设门限，则该控制网元按照该第一干扰与噪声、该第二干扰与噪声和该第三干扰与噪声的平均值从大到小的顺序，将前M个基站确定为该第一待检基站。
在一种可能的设计中，控制网元基于该干扰指标从该N个基站的邻站中确定M个第一待检基站，包括：
若N大于或等于预设阈值，且该N个基站的该第一干扰与噪声小于预设门限，则该控制网元分别确定各基站的邻站与N个基站的邻站关系数量；
该控制网元按照该邻站关系数量从多到少的顺序，将前M个邻站确定为该第一待检基站，其中，该邻站关系包括各基站的邻站与N个基站之间的邻站关系。

上述各可能的设计所提供的失步确定方法，通过上报干扰指标的基站的多少，以及干扰指标的大小，从N个基站和/或N个基站的邻站中确定M个第一待检基站，由此可以在不同的场景中，应用不同的方式确定第一待检基站，从而提高第一待检基站确定的灵活性。

具体实施方式
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解：
基站：又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是长期演进(Long Term Evolution，简称LTE)中的演进型基站(Evolutional Node B，简称eNB或eNodeB)，或者中继站或接入点，或者未来5G网络中的基站等，在此并不限定。
控制网元，即集中判断控制网元，其是一个逻辑网元，可以独立布署，也可以和网管或基站合一布署，本申请实施例中，控制网元和网管合一布署。其中，网管为网络设备融合管理系统，其用于统一管理网络中的其他设备，网管例如可以为U2000等。在本申请中，控制网元集成在网管中,可以用于在有基站发生失步，并对其他基站产生干扰时，基于各基站上报的干扰指标确定出失步的基站，该控制网元还可以具备其他功能，本申请对此并不限制。
图1为本申请实施例提供的网络架构示意图，如图1所示，该网络架构中包括控制网元和多个基站，该控制网元集成在网管中，其中，控制网元和基站之间，有两种消息接口，一种是二进制消息接口，包括基站干扰上报、控制网元给基站下发检测消息和静默检测消息，基站给控制网元上报序列检测结果和静默检测结果都用的是二进制消息接口。还有一种是人机语言(Man-Machine Language；MML)命令接口，控制网元可以通过该接口下发消息，以查询某个基站的邻站等。
本申请实施例提供的失步确定方法，适用于同频连续覆盖的场景中，其中，由于个别基站时钟失步，会造成周边同步基站受到干扰或者失步的基站自身受到干扰，常用的确定失步的方式为若基站中的时钟参考源丢失，通常会有相应的告警提示，以通过告警提示确定出失步的基站，另外，失步的基站会做相应的重新同步或者复位操作，并且时钟参考源丢失的时间超过预设的时间段之后，基站将会自动闭塞载扇，以防止基站对其他相邻同频小区造成干扰。然而，若时钟参考源正常，但由于软件缺陷或者后端器件失效而导致基站时钟失步时，将无法进行告警提示，此时将无法发现失步的基站，从而导致确定失步的准确性较差。
因此，本申请提供的失步确定方法和装置，旨在解决现有技术中确定失步的基站时误差较大，准确性较差的技术问题。
下面以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本申请实施例提供的失步确定方法实施例一的流程示意图。本申请实施例提供了一种失步确定方法，该方法可以由任意执行失步确定方法的装置来执行，该装置可以通过软件和/或硬件实现。本实施例中，该装置可以集成在控制网元中。如图2所示，本实施例的方法可以包括：
步骤201、控制网元接收N个基站发送的干扰指标。
其中，干扰指标包括第一干扰与噪声(Interference and Noise；IN)IN1、第二干扰与噪声IN2和第三干扰与噪声IN3，其中，第一干扰与噪声、第二干扰与噪声和第三干扰与噪声分别是上行子帧不同符号受到的干扰。另外，N为正整数。
步骤202、控制网元基于该干扰指标从N个基站和/或N个基站的邻站中确定M个第一待检基站。
在本实施例中，N个基站将分别监控本站所有小区的干扰指标，当发现存在某个小区的干扰指标超过预设阈值时，需要把小区级别的干扰汇总成基站级别，并向控制网元上报IN1、IN2和IN3，其中，IN1、IN2和IN3分别为不同符号上的干扰。具体地，通常是以基站或频点级别进行上报，如果频点相同，即频段中的一个中心点相同时，基站将上报受扰最强的小区指标。若一个基站下有多个频点时，将会通过多条消息上报给控制网元，或者可以通过携带有多个频点信息的一条消息上报给控制网元。
控制网元接收到各基站上报的干扰指标后，将从N个基站和/或N个基站的邻站中确定出M个第一待检基站进行后续检测，由于失步的基站和同步的基站干扰符号位置和特征存在差异，所以可以根据干扰符号位置、干扰强度、干扰基站个数等特征来确定各基站是否失步，以此选择第一待检基站。
其中，基站监控并上报干扰指标的主要功能是发现时钟失步干扰，并触发检测，同时又要避免其它干扰触发失步检测流程，其中，其它干扰包括大气波导和大事件产生的干扰特征，大事件通常为大话务量事件，具体地，基站在向控制网元上报干扰指标前，需要判断检测到的干扰指标超过预设门限是否是由大气波导或大事件引起，如果是由大气波导或大事件引起的干扰抬升，则基站不向控制网元上报干扰指标。
另外，控制网元从N个基站和/或N个基站的邻站中确定出M个第一待检基站包括以下三种情况：(1)控制网元从N个基站中确定出M个第一待检基站；(2)控制 网元从N个基站的邻站中确定出M个第一待检基站；(3)控制网元从N个基站和N个基站的邻站中确定出M个第一待检基站。
由于只要发生时钟失步并产生干扰，则必然存在基站上行子帧的最后几个符号受到干扰的现象(可能是同步的基站受干扰，也可能是失步的基站受干扰)，所以，如果发现有基站上行子帧的最后几个符号受到干扰，则可以判断此时可能存在时钟失步，因此，基站需要在每个周期，检测本站所有小区的干扰情况。
图3为上行子帧的平均干扰功率的示意图，图4为上行子帧的平均干扰功率的示意图，如图3和图4所示，基站每个周期会计算不同符号的上行干扰平均值，如果存在某个小区最后一个上行子帧的最后几个符号上的平均干扰功率大于门限，则说明该小区的干扰特征符合时钟失步干扰特征。在本实施例中，基站每个周期会计算IN1、IN2和IN3上的干扰，如果最后一个上行子帧的时隙1(Slot1)上的IN3平均干扰功率大于门限，并且判断不是大事件引起的干扰抬升，则基站将IN1、IN2和IN3都上报给控制网元。值得注意的是，本实施例中是以配比1和配比2的情况进行说明，在实际应用中，本实施例对于任意配比都适用。
另外，需要说明的是，如图3-图4所示，IN2也可以是最后一个子帧Slot0的前几个符号，如Slot0的前4个符号。图3和图4所示为一个完整的Slot0，其中，一般循环前缀(Normal CP)为7个符号，扩展循环前缀(Extended CP)为6个符号。IN3也可以是Slot1的后几个符号，如4个符号，图3和图4中为一个完整的Slot1。
另外，当失步的基站时钟发生偏移产生干扰时，失步的基站和同步的基站在干扰强度、干扰符号位置、干扰基站数量方面会存在差异，通过这些特征能够直接找到失步的基站或者缩小失步的基站的范围。在实际应用中，确定第一待检基站可以包括如下几种情况：
第一种：若N小于预设阈值，则控制网元将N个基站均确定为第一待检基站。
具体地，图5为基站上报干扰指标的示意图，如图5所示，本领域技术人员可以理解，失步基站上行子帧2(U)中的最后几个符号(8、9、10、11、12、13)受到了同步基站1、同步基站2和同步基站3的下行子帧3(D)的干扰，即失步基站Slot1中的最后几个符号受到干扰，结合图2和图3所示，即只有失步的基站的IN3受到干扰，通常只有失步的基站会进行干扰上报。因此，若在某个周期内，向控制网元上报干扰指标的基站的数量小于预设阈值，即N小于预设阈值时，则可以认为上报干扰指标的N个基站存在失步的可能，此时，可以直接将上报干扰指标的这N个基站确定为第一待检基站，在这种情况下，N等于M。其中，预设阈值可以根据实际情况或者经验进行设置，例如可以设置为1或2等，对于预设阈值的具体取值，本实施例在此不作限制。
第二种：若N大于或等于预设阈值，则分别判断N个基站的IN1、IN2和IN3是否均大于预设门限；若N个基站的IN1、IN2和IN3均大于预设门限，则控制网元按照干扰指标IN1、IN2和IN3的平均值从大到小的顺序，将前M个基站确定为第一待检基站。
具体地，图6为基站上报干扰指标的示意图，如图6所示，本领域技术人员可以理解，同步基站1、同步基站2和同步基站3的特殊子帧1(S)的后几个符号、上行 子帧2(U)受到了失步基站下行子帧0(D)的干扰，即同步基站1、同步基站2和同步基站3中的Slot0和Slot1受到干扰，另外，失步基站的特殊子帧1(S)的后几个符号、上行子帧2(U)受到了同步基站1、同步基站2和同步基站3下行子帧3(D)的干扰，结合图2和图3所示，这种场景下，由于同步的基站和失步的基站干扰特征类似，都是IN1、IN2和IN3受到干扰，同步的基站和失步的基站都会进行干扰上报。因此，若在某个周期内，向控制网元上报干扰指标的基站的数量大于或等于预设阈值，即N大于或等于预设阈值时，则判断各基站的IN1、IN2和IN3是否均大于预设门限，若各基站的IN1、IN2和IN3均大于预设门限时，将选择平均干扰最强的M个基站确定为第一待检基站，即按照干扰指标的平均值从大到小的顺序，将前M个基站确定为第一待检基站，例如：按照IN1、IN2和IN3的平均值从大到小的顺序，将前M个基站确定为第一待检基站。其中，预设阈值例如可以为2。
第三种：若N大于或等于预设阈值，且N个基站的IN1小于预设门限，则控制网元分别确定N个基站的邻站与N个基站的邻站关系数量的数量；控制网元按照邻站关系数量从多到少的顺序，将前M个基站确定为第一待检基站，其中，邻站关系包括各基站的邻站与N个基站之间的邻站关系。
具体地，图7为基站上报干扰指标的示意图，如图7所示，本领域技术人员可以理解，同步基站1、同步基站2和同步基站3的上行子帧2(U)的后几个符号受到了失步基站下行子帧3(D)的干扰，即同步基站1、同步基站2和同步基站3中的Slot1受到干扰，结合图2和图3所示，在这种场景下，由于只有同步基站的IN3受到干扰，所以只有同步基站会进行干扰上报。因此，若在某个周期内，向控制网元上报干扰指标的基站的数量大于或等于预设阈值，且各基站的IN1小于预设门限时，第一待检基站将在各个基站的邻站中进行选择，在实际应用中，控制网元将分别确定各个基站的邻站与N个基站的邻站关系数量，并将邻站关系数量最多的M个基站确定为第一待检基站。其中，预设阈值例如可以为2等。
举例来说，若M为2，假设N个基站分别为A基站、B基站、C基站、D基站和E基站，其中，A基站的邻站为a基站、b基站和c基站，B基站的邻站为a基站、d基站和c基站，C基站的邻站为A基站、a基站、b基站和d基站，D基站的邻站为A基站、a基站、c基站和d基站，E基站的邻站为A基站、B基站、b基站、c基站、e基站、f基站、g基站、h基站和i基站，则a基站与A基站、B基站、C基站和D基站存在邻站关系，因此，a基站的邻站关系数量为4，b基站与A基站、C基站和E基站存在邻站关系，因此，b基站的邻站关系数量为3，用类似的方式，确定出c基站的邻站关系数量为4，d基站的邻站关系数量为3，e基站的邻站关系数量为1，f基站的邻站关系数量为1，g基站的邻站关系数量为1，h基站的邻站关系数量为1，i基站的邻站关系数量为1，确定出邻站关系数量之后，控制网元将按照邻站关系数量从多到少的顺序，将a基站和c基站确定为第一待检基站。
第四种：若N大于或等于预设阈值，则控制网元按照干扰指标IN1、IN2和IN3的平均值从大到小的顺序，将前L个基站，以及按照邻站关系数量从多到少的顺序，将前P个基站确定为第一待检基站，其中，邻站关系包括各所述基站的邻站与N个基站之间的邻站关系，L和P为整数，且L和P的和等于M。
具体地，若在某个周期内，向控制网元上报干扰指标的基站的数量大于或等于预设阈值，即N大于或等于预设阈值时，则第一待检基站将包括两部分，第一部分可以按照第二种方式，即按照干扰指标的平均值从大到小的顺序，选择前L个基站作为第一待检基站，第二部分可以按照第三种方式，即按照邻站关系数量从多到少的顺序，将前P个基站确定为第一待检基站，其中，具体的确定方式与第二种方式与第三种方式中类似，此处不再赘述。
步骤203、控制网元确定P个第二待检基站；该P个第二待检基站为从M个第一待检基站中选择出的满足检测条件的基站，检测条件为第一待检基站在无线帧的指定位置广播的特征序列均不能被邻站在该指定位置接收。
其中，P为整数，P小于或等于M。在本实施例中，控制网元确定出M个第一待检基站之后，将从M个第一待检基站以及各第一待检基站的邻站中选择第二待检基站。在实际应用中，可以依据TDD系统要求时钟严格同步的原则，第一待检基站在预设无线帧的预设位置发送特征序列，如果同步，则第一待检基站的邻站将在预设无线帧的预设位置可以正常接收到该特征序列；如果失步，则因为错过接收检测窗，导致第一待检基站的邻站将无法检测到特征序列。
类似的，第一待检基站的邻站发送特征序列，第一待检基站检测到序列，也可以判定第一待检基站同步。如果第一待检基站发送的特征序列邻站都无法接收到，并且邻站发送的特征序列，第一待检基站也无法接收到，则判定第一待检基站可能失步，将其确定为第二待检基站。
本实施例中，当第一待检基站的邻站同时也是第一待检基站时，才会发送特征序列，也就是说本实施例中只有第一待检基站才会发送特征序列，但是本申请并不限定只有第一待检基站才发送特征序列的情形。对于邻站发送特征序列，第一待检基站接收特征序列的方式和原理，与第一待检基站发送特征序列，邻站接收特征序列的方式和原理类似，此处不再赘述。
可选地，图8为本申请实施例提供的控制网元确定第二待检基站的流程示意图，如图8所示，上述步骤202具体可以包括：
步骤801、控制网元分别向M个第一待检基站发送第一通知消息，该第一通知消息用于指示第一待检基站在无线帧的预设位置上广播特征序列。
具体地，控制网元将分别向确定出的M个第一待检基站发送第一通知消息，各第一待检基站根据接收到的通知消息，会在无线帧的预设位置上广播特征序列。其中，无线帧的预设位置例如可以为S子帧的GP区，当然，还可以为无线帧的其他位置。需要进行说明的是，不同的第一待检基站如果同时广播特征序列时，将会在不同的无线帧的指定位置上进行广播，例如：比如第一待检基站A和第一待检基站B同时广播特征序列时，第一待检基站A在801无线帧的指定位置发送特征序列，第一待检基站B在802无线帧的指定位置发送特征序列等。
步骤802、控制网元向各第一待检基站的邻站发送第二通知消息，第二通知消息用于指示第一待检基站的邻站在无线帧的预设位置上接收特征序列。
具体地，控制网元首先需要确定出各第一待检基站的所有邻站，在具体的实现过 程中，控制网元可以向各第一待检基站发送查询消息，第一待检基站将根据该查询消息，确定出所有与自身有邻接关系的基站，并将这些邻站的标识信息携带在反馈消息中发送给控制网元。另外，如果控制网元部署在网管中时，也可以在网管上通过配置信息直接查询各第一待检基站的邻站信息。对于控制网元确定第一待检基站的邻站的具体方式，本实施例在此不作限定。
控制网元根据接收到的反馈消息，向标识信息对应的基站发送第二通知消息。各第一待检基站的邻站根据该第二通知消息，将会在无线帧的预设位置上接收特征序列。
步骤803、控制网元分别接收各第一待检基站的邻站发送的第一响应消息，第一响应消息用于指示第一待检基站的邻站是否接收到特征序列。
具体地，各第一待检基站的邻站在无线帧的预设位置上接收特征序列之后，将会向控制网元反馈接收结果，即各邻站将分别向控制网元发送第一响应消息，以通知控制网元其是否在无线帧的预设位置上接收到特征序列。
另外，若第一待检基站A在801无线帧的指定位置发送特征序列，第一待检基站B在802无线帧的指定位置发送特征序列，则第一待检基站A和第一待检基站B的邻站在801无线帧的指定位置和802无线帧的指定位置，以判断在801无线帧的指定位置是否有邻站接收到特征序列，在802无线帧的指定位置是否有邻站接收到特征序列等。
步骤804、若控制网元根据第一响应消息，确定出第一待检基站的所有邻站均未接收到特征序列，则将第一待检基站确定为第二待检基站。
具体地，依据TDD系统要求时钟严格同步的原则，第一待检基站在S子帧GP区发送特征序列之后，如果所有基站的时钟都同步，则第一待检基站的邻站可以在S子帧GP区正常接收到特征序列，如果第一待检基站时钟失步，则第一待检基站的邻站可能会因为错过接收检测窗，导致无法检测到特征序列。因此，若控制网元根据各第一待检基站的邻站发送的第一响应消息，确定出某个第一待检基站的所有邻站均未接收到该第一待检基站在无线帧的预设位置发送的特征序列，则可以将该第一待检基站确定为第二待检基站，以后续进行进一步确认。另外，如果某个第一待检基站同时为其他第一待检基站的邻站时，不仅需要判断该第一待检基站的邻站是否接收到特征序列，还需要判断其自身是否在无线帧的预设位置处接收到其他第一待检基站发送的特征序列。
举例来说，若第一待检基站包括A基站、B基站和C基站，其中，A基站的邻站为a基站、b基站和c基站，B基站的邻站为a基站、d基站和c基站，C基站的邻站为A基站、a基站、b基站和d基站。当A基站、B基站和C基站分别在无线帧的预设位置发送特征序列之后，各自的邻站将会在无线帧的预设位置接收特征序列，若A基站的邻站a基站、b基站和c基站均未在无线帧的预设位置上接收到特征序列，且A基站也没有接收到C基站发送的特征序列，则将A基站确定为第二待检基站。
本实施例提供的确定第二待检基站的方法，由于各第一待检基站分别在无线帧的预设位置上发送特征序列，控制网元将判断每个第一待检基站的所有邻站是否在无线帧的预设位置上接收到该特征序列，若第一待检基站时钟失步，则第一待检基站的邻站可能会因为错过接收检测窗，导致无法检测到特征序列，由此可以确定出可能失步 的第二待检基站，从而使得第二待检基站的确定更加准确。
可选地，图9为本申请实施例提供的控制网元确定第二待检基站的流程示意图，本实施例中确定第二待检基站的方式与图8中确定第二待检基站的方式之间的区别在于，本实施例中各第一待检基站在无线帧的预设位置上发送特征序列，且各第一待检基站的邻站在该无线帧的预设位置上接收特征序列之后，邻站将是否接收到特征序列的结果反馈给第一待检基站，并由第一待检基站判断所有邻站是否接收到特征序列，由此确定第二待检基站，并将第二待检基站的标识信息发送给控制网元。如图9所示，上述步骤202具体可以包括：
步骤901、控制网元分别向M个第一待检基站发送第一检测消息，该第一检测消息用于指示第一待检基站在无线帧的预设位置上发送特征序列。
具体地，控制网元可以分别向M个第一待检基站发送第一检测消息，该第一检测消息中携带有基站的标识信息和无线帧之间的映射关系。各第一待检基站根据接收到的第一检测消息，查找本站的所有邻站，并向所有的邻站发送通知消息，该通知消息用于指示邻站在无线帧的预设位置上接收特征序列。另外，各第一待检基站根据基站的标识信息和无线帧之间的映射关系，确定自身的标识信息所对应的无线帧，也即确定出自身在哪个无线帧的预设位置上发送特征序列，当各第一待检基站在确定出的无线帧的预设位置上发送特征序列后，本站的所有邻站将在对应的无线帧的预设位置上接收特征序列，且所有邻站将会向第一待检基站返回响应消息，该响应消息中携带有邻站是否接收到特征序列的结果信息，第一待检基站根据响应消息中携带的结果信息，确定第二待检基站。在具体的实现过程中，若第一待检基站根据响应消息，确定出本站的所有邻站均未在对应的无线帧的预设位置上接收到特征序列，则将第一待检基站确定为第二待检基站。
步骤902、控制网元分别接收M个第一待检基站发送的第一反馈消息，该第一反馈消息中包括第一待检基站确定出的各第二待检基站的标识信息。
具体地，各第一待检基站在确定出第二待检基站之后，将第二待检基站的标识信息携带在第一反馈消息中发送给控制网元。其中，若第一待检基站确定出本站的所有邻站均在无线帧的预设位置上接收到了特征序列，则说明第一待检基站的时钟没有失步，此时，第一待检基站可以不用向控制网元发送第一反馈消息，或者第一待检基站向控制网元发送的控制消息中不携带任何基站的标识信息。
步骤903、控制网元根据标识信息确定第二待检基站。
具体地，控制网元在接收到第一待检基站发送的第一反馈消息之后，将第一反馈消息中的标识信息对应的基站确定为第二待检基站。另外，若控制网元没有接收到第一待检基站发送的第一反馈消息，或者接收到的第一反馈消息中不携带任何基站的标识信息时，将确定不存在第二待检基站，此时，第一待检基站的时钟处于同步的状态。
本实施例提供的确定第二待检基站的方法，由于各第一待检基站分别在无线帧的预设位置上发送特征序列，并判断所有邻站是否在该无线帧的预设位置上接收到特征序列，由此确定自身是否为第二待检基站，从而将判断出的结果发送给控制网元，由此可以提高第二待检基站确定的效率。
步骤204、控制网元从P个第二待检基站中确定失步的基站。
在本实施例中，控制网元在确定出P个第二待检基站之后，将通过静默检测的方式，确定出失步的基站。由于控制网元通过在无线帧的预设位置上发送和接收特征序列，以及静默检测的方式，最终确定出失步的基站，从而可以提高失步确定的准确性。
可选地，图10为本申请实施例提供的控制网元从P个第二待检基站中确定失步的基站的流程示意图，如图10所示，上述步骤203具体可以包括：
步骤1001、控制网元依次向P个第二待检基站发送第三通知消息，并向第二待检基站的邻站发送第四通知消息，其中，控制网元在接收到第i个第二待检基站的邻站发送的第二响应消息之后，向第i+1个第二待检基站发送第三通知消息，并向第i+1个第二待检基站的邻站发送第四通知消息。
其中，该第三通知消息用于指示各第二待检基站在预设无线帧上处于静默状态，第四通知消息用于指示邻站在第二待检基站处于静默状态时进行干扰检测，第二响应消息用于指示在所述第二待检基站处于静默状态时，各所述第二待检基站的邻站检测自身受到的干扰是否发生变化。
具体地，控制网元将依次向P个第二待检基站发送第三通知消息，并向第二待检基站的邻站发送第四通知消息，第i个第二待检基站在接收到第三通知消息之后，将在预设无线帧上处于静默状态，其中，预设无线帧可以是几个连续的无线帧，如指示第二待检基站在第2个无线帧至第7个无线帧上处于静默状态等，也可以是若干个不连续的无线帧，如指示第二待检基站在第2个无线帧、第4个无线帧，第6个无线帧和第7个无线帧时处于静默状态等。
另外，控制网元还会向第二待检基站的邻站发送第四通知消息，以指示该第二待检基站的所有邻站在预设无线帧上，即第二待检基站处于静默状态时进行干扰检测。举例来说，若某个第二待检基站在第2、第4、第6和第7无线帧时处于静默状态，该第二待检基站的所有邻站将延迟若干秒后进行干扰检测，以保证邻站先执行检测并持续整个静默可能的周期，以提高干扰检测的准确性。在实际应用中，第二待检基站的邻站接收到第四通知消息，并延迟若干秒之后，将在每个无线帧上进行上行干扰检测并进行静默图谱的匹配，以判断干扰变化是否符合第二待检基站执行静默时的静默图谱。
当第i个第二待检基站的邻站检测完成之后，会向控制网元发送第二响应消息，以通知控制网元，在该第二待检基站处于静默状态时，自身所受到的干扰是否发生变化。控制网元在接收到第i个第二待检基站的邻站发送的第二响应消息之后，再向第i+1个第二待检基站发送第三通知消息，并向第i+1个第二待检基站的邻站发送第四通知消息，第i+1个第二待检基站的邻站将会进行干扰检测，并向控制网元上报检测结果，依次类推，直至完成P个第二待检基站的检测。
在实际应用中，当邻站在每个无线帧上进行上行干扰检测，并进行静默图谱的匹配之后，若干扰变化符合静默图谱，即在第二待检基站处于静默状态时，其邻站在此期间受到的干扰也发生了变化(干扰下降的时长和频次和第二待检基站静默保持同步)，则邻站将记录当前符合静默图谱的第一个无线帧号(或者第N个，本申请不做限定，只要所有基站保持一致即可)，并将记录的无线帧号携带在第二响应消息中发送给控制网元。
步骤1002、控制网元根据第二响应消息，确定失步的基站。
具体地，由于干扰是由失步的基站在不正确的时序上发功造成的，因此，控制网元根据第二响应消息，确定失步的基站包括若控制网元根据第二响应消息，确定出第二待检基站在预设无线帧上处于静默状态时，各第二待检基站的邻站在预设无线帧上检测到的干扰发生变化，则将第二待检基站确定为失步的基站。也即如果第二待检基站静默所有下行子帧后，其邻站干扰消除，则可以确定该第二待检基站为失步的基站；如果其邻站的干扰没有消除，则该第二待检基站是同步的基站。在具体的实现过程中，控制网元在接收到第二响应消息中携带的无线帧号后，将判断是否存在某个第二待检基站的两个邻站上报的无线帧号有效并且差值小于或等于1，若判断出存在两个邻站上报的无线帧号有效并且差值小于或等于1时，将确定该第二待检基站为失步的基站。另外，确定出失步的基站后，控制网元还将发出告警信息，并对失步的基站执行自愈操作，以防止失步的基站对其他相邻同频小区造成干扰。举例来说，若某个第二待检基站在第2、第4、第6和第7无线帧时处于静默状态，且该第二待检基站的邻站检测出自身在第N、第N+2、第N+4和第N+5无线帧时干扰消除，此时，则将确定第二待检基站为失步的基站。需要说明的是，由于第二待检基站有可能处于失步状态，因此，第二待检基站的第2无线帧，不一定是邻站的第2无线帧，故邻站只要检测出自身所受的干扰变化符合静默图谱即可，并不要求无线帧一致。
本实施例提供的失步确定方法，由于第二待检基站在预设无线帧上执行下行静默后，邻站将在该预设无线帧上进行干扰检测，从而判断在第二待检基站处于静默状态时，自身所受的干扰是否发生变化，若控制网元判断出某个第二待检基站的邻站在该预设无线帧上所受的干扰发生了变化，并且变化规律符合第二待检基站的静默图谱，则可以确定出该第二待检基站为失步的基站，从而可以提高失步确定的准确性。
可选地，图11为本申请实施例提供的控制网元确定失步的基站的又一流程示意图，本实施例中确定失步的基站的方式与图10中确定失步的基站的方式之间的区别在于，本实施例中各第二待检基站在预设无线帧上处于静默状态，且各第二待检基站的邻站在该预设无线帧上检测自身所受到的干扰，并将检测到的结果反馈给第二待检基站，由第二待检基站判断其的所有邻站检测到的干扰是否发生变化，由此确定失步的基站，并将失步的基站的标识信息发送给控制网元。如图11所示，上述步骤203具体可以包括：
步骤1101、控制网元依次向P个第二待检基站发送第二检测消息，其中，控制网元在接收到第i个第二待检基站发送的第二反馈消息之后，向第i+1个第二待检基站发送第二检测消息，该第二检测消息用于指示第二待检基站在预设无线帧上处于静默状态，第二反馈消息中包括第二待检基站确定出的失步的基站的标识信息。
具体地，控制网元在确定出P个第二待检基站之后，将依次向各个第二待检基站发送第二检测消息，以指示第二待检基站在预设无线帧上处于静默状态。其中，控制网元将在接收到第i个第二待检基站发送的第二反馈消息之后，再向第i+1个第二待检基站发送第二检测消息，以轮流对各个第二待检基站进行检测。
具体地，第二待检基站在接收到第二检测消息后，将根据该第二检测消息确定失步的基站，其中，失步的基站为满足检测条件的基站，该检测条件为在第二待检基站 处于静默状态时，第二待检基站的邻站检测到的干扰发生变化。在具体的实现过程中，第二待检基站根据检测消息确定失步的基站，包括：第二待检基站向所有邻站发送通知消息，该通知消息用于指示邻站检测在所述第二待检基站处于静默状态时自身受到的干扰；第二待检基站将在预设无线帧内设置为静默状态；第二待检基站接收各邻站发送的响应消息，并根据响应消息确定失步的基站，该响应消息用于指示在第二待检基站处于静默状态时，各第二待检基站的邻站检测到的干扰是否发生变化。具体地，若第二待检基站根据响应消息，确定出第二待检基站在预设无线帧内处于静默状态时，第二待检基站的各邻站在预设无线帧内检测到的干扰发生变化，则将第二待检基站确定为失步的基站。
在具体的实现过程中，对于每一个第二待检基站，其在延迟若干秒后根据静默图谱，即在预设无线帧内执行下行静默，该第二待检基站的邻站将在每个无线帧上进行上行干扰检测，并进行图谱匹配，以判断干扰变化是否符合第二待检基站执行静默时的静默图谱。若干扰变化符合静默图谱，即在第二待检基站处于静默状态时，其邻站在此期间受到的干扰也发生了变化，则邻站将记录当前的无线帧号，并将记录的无线帧号携带在响应消息中发送给第二待检基站。第二待检基站在接收到响应消息中携带的无线帧号后，将判断是否存在两个邻站上报的无线帧号有效并且差值小于或等于1，若判断出存在两个邻站上报的无线帧号有效并且差值小于或等于1时，将确定第二待检基站为失步的基站，并将自身的标识信息携带在第二反馈消息上报给控制网元。
步骤1102、控制网元根据标识信息确定失步的基站。
具体地，控制网元根据接收到的标识信息，将标识信息对应的基站确定为失步的基站，另外，控制网元还将向失步的基站发出告警信息，并对失步的基站执行自愈操作，以防止失步的基站对其他相邻同频小区造成干扰。
本实施例提供的失步确定方法，由于第二待检基站在预设无线帧内执行下行静默后，邻站将在该预设无线帧内进行干扰检测，从而判断在第二待检基站处于静默状态时，自身所受的干扰是否发生变化，若第二待检基站判断出其的邻站在该预设无线帧内所受的干扰发生了变化，则可以确定其自身为失步的基站，并将判断结果发送给控制网元，以使控制网元对失步的基站执行自愈操作，由此可以提高失步确定的效率。
本实施例提供的失步确定方法，通过接收N个基站发送的干扰指标，并根据干扰指标，从N个基站和/或N个基站的邻站中确定M个第一待检基站，并确定P个第二待检基站，其中，P个第二待检基站为从M个第一待检基站中选择出的满足检测条件的基站，其中，检测条件为第一待检基站在无线帧的指定位置广播的特征序列均不能被邻站在指定位置接收，再从P个第二待检基站中确定失步的基站。由于控制网元根据基站上报的干扰指标先选择出M个第一待检基站，再根据邻站是否能够在无线帧的指定位置接收到第一待检基站在该无线帧的指定位置发送的特征序列，来选择出满足检测条件的第二待检基站，最终确定出失步的基站，由于通过不同的方式逐步缩小失步的基站确定的范围，从而可以提高失步确定的准确性。
