技术领域
本发明涉及通信技术领域，特别是涉及一种拓扑组网识别方法、装置、电子设备及存储介质。
背景技术
随着集中式无线接入网(Centralized Radio Access NetWork，CRAN)，尤其是在网络中引入无源的波分复用器(Optical Multiplexer Demultiplexer，OMD)后，整个前传链路大致分为室内基带单元(Building Baseband Unite，BBU)侧设备+尾纤、近端波分器、主干光纤、远端波分器、射频单元(Remote Radio Unit，RRU)侧设备+尾纤。由于OMD为无源设备，监控端无法对OMD进行有效建模和监控，进而导致了波分器和主干光纤故障定界定位的困难，给运营商带来了高昂的运维成本。

此外，下面所描述的本申请各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以相互组合。
本申请实施例涉及的拓扑组网识别方法，是基于集中式无线接入网。目前CRAN设备已经是网络设备的主流部署形态，网络设备的BBU与RRU之间通过光纤连接，而BBU与RRU之间的距离较远，为了节约光纤资源，可以采用波分复用(Wavelength Division Multiplexing，WDM)技术实现光纤复用，即多个射频单元复用一根光纤，以提高了光纤的利用率。如图1所示，本申请实施例提供的一种拓扑组网的结构图可以看出，在CRAN组网引入OMD后，整个前传链路大致分为BBU侧设备+尾纤、近端波分器、主干光纤、远端波分器、RRU侧设备+尾纤。由于OMD无源，网管端上无法对OMD进行有效的建模和监控，进而导致了波分设备和主干光纤的故障难以进行快速的定界定位，给运营商带来了高昂的运维成本。
为了保证网络性能测量系统能监测网络当前运行状态，准确测量网络单元之间的时延值，现有技术中，拓扑组网识别方法是基于专家规则，尤其是基于射频单元到所连基带单元端口的传输距离和光模块波长，按照任意两个射频单元对应传输距离之差不大于经验阈值且对应光模块波长不同原则，将多个射频单元划分入一个波分设备组。但是该方法目前存在以下问题：如果射频单元到基带单元之间链路异常，由于无法采集对应传输距离，现有的拓扑组网识别方法无法及时得到波分设备拓扑组网；其次，专家规则严重依赖传输距离经验阈值。在实际应用中，通常采用时延来测量光路传输距离，这种测量方法误差大且测量结果不稳定，在此基础上设置的传输距离误差阈值，容易带来拓扑组网识别的误判；最后，在一个基带单元连接多套波分设备场景中，同一个基带板下能连接同一种类型波分设备，多个波分设备组的多个射频单元传输距离相近且光模块波长范围也一样，仅使用专家规则显然无法有效识别哪些射频单元同属于一个波分设备组。
基于以上，本申请实施例提供一种拓扑组网识别方法、装置、电子设备和计算机可读存储介质，通过获取多个基带单元和射频单元的波长信息，其中，波长信息包括基带单元和射频单元之间光模块的主波长；采集射频单元的链路告警信息，得到告警集合；聚类处 理告警集合，得到多个告警组；根据波长信息，将告警组内的射频单元和与射频单元相连的基带单元分入同一个波分设备组，能够快速准确地识别出无线接入网的拓扑组网，提高了拓扑组网识别的准确性和网络单元的维护便利性。
请参见图2，图2示出了本申请实施例提供的一种拓扑组网识别方法的流程。如图2所示，本申请实施例的拓扑组网识别方法包括以下步骤：
S1000，获取多个基带单元和射频单元的波长信息，其中，波长信息包括基带单元和射频单元之间光模块的主波长。
可以理解的是，随着CRAN设备的广泛应用,多个射频单元复用一根光纤与基带单元连接。其中，基带单元和射频单元上均设有一一对应的光模块，基带单元上的光模块通过尾纤与波分设备连接，射频单元上的光模块同样通过尾纤与波分设备连接。波分设备之间再通过主干光纤，以实现基带单元和射频单元之间的连接。可以理解的是，采用WDM技术实现光纤复用，提高了BBU与RRU之间的光纤利用率，属于现有技术，此处不再赘述。
可以理解的是，网络设备中采用的波分设备会对RRU端口和BBU端口的光模块波长进行规范，其中不同波分设备对RRU端口和BBU端口的光模块的主波长的规范不同，以波分设备为6波的稀疏波分设备(Coarse Wavelength Division Multiplexer，CWDM)为例，根据6波的CWDM波分设备对光模块波长规范，RRU端口的光模块波长可以为1271nm、1291nm和1311nm，BBU端口的光模块波长可以为1331nm、1351nm和1371nm。可以理解的是，网管服务器能通过查询指令获取多个基带单元的光模块和射频单元的光模块的资产信息，进而读取基带单元和射频单元的波长信息，属于现有技术，此处不再赘述。
S2000，采集射频单元的链路告警信息，得到告警集合。
可以理解的是，在无线网络的运行过程中，射频单元会因为RRU交流掉电、RRU直流掉电、未上电或运行异常；BBU与RRU之间或者上下级RRU之间的光纤或者电缆故障；BBU或RRU光模块故障；RRU或BBU单板硬件故障等原因，导致射频单元与基带单元之间的通信链路发生异常，进而上报射频单元的链路告警信息，并被网管服务器采集和存储。可以理解的是，网管服务器能通过指令查询和存储射频单元的链路告警信息，进而读取链路告警信息对应的射频单元和上报时间，属于现有技术，此处不再赘述。
请参见图3，图3示出了上述步骤S2000的另一实施例的具体实现过程示意图。如图3所示，步骤S2000至少包括以下步骤：
S2100，获取射频单元的链路告警信息。
可以理解的是，在射频单元与基带单元之间的通信链路发生异常的情况下，网管服务 器能获取由射频单元上报的链路告警信息。在实际应用中，导致链路告警信息的具体原因如下：在BBU和下级RRU连接链路采用光接口时，可能是BBU或下级RRU的光纤接头或光模块未插紧，或光纤链路故障；在多模的场景下，BBU互联线缆异常或者BBU互联端口光模块故障；BBU或下级射频单元运行异常或硬件故障。当射频单元与基带单元之间的通信链路发生异常，射频单元主动向网管服务器上报链路告警信息，以使网管服务器及时掌握射频单元与基带单元之间的链路情况。
S2200，根据链路告警信息的上报时间的先后顺序正序或者倒序排列链路告警信息，以生成告警集合。
可以理解的是，射频单元的链路告警信息包括但不仅限于射频单元ID、与射频单元相连的基带单元ID、告警内容以及上报时间。因此，能通过链路告警信息的上报时间对链路告警信息进行排列，生成告警集合，便于对链路告警信息进行分析处理。可以理解的是，能根据链路告警信息的上报时间的先后顺序正序排列链路告警信息，也能根据链路告警信息的上报时间的先后顺序倒序排列链路告警信息，提高网管服务器对链路告警信息的处理效率。
S3000，聚类处理告警集合，得到多个告警组。
可以理解的是，聚类处理是运用形态学算子将临近的类似分类区域聚类并合并。聚类是数据挖掘中的概念，就是按照某个特定标准(如距离)把一个数据集分割成不同的类或簇，使得同一个簇内的数据对象的相似性尽可能大，同时不在同一个簇中的数据对象的差异性也尽可能地大。也即聚类后同一类的数据尽可能聚集到一起，不同类数据尽量分离。本申请实施例中，以时间间隔作为样本距离，通过对告警集合进行聚类处理，输出在时间上高度集中的多个告警组。
可以理解的是，本申请实施例中采用基于密度的聚类算法(Density-Based Spatial Clustering of Applications with Noise，DBSCAN)，这是一个比较有代表性的聚类算法。与划分和层次聚类方法不同，它将簇定义为密度相连的点的最大集合，能够把具有足够高密度的区域划分为簇，并可在噪声的空间数据库中发现任意形状的聚类。DBSCAN是一种基于密度的空间聚类算法,它不需要定义簇的个数,而是将具有足够高密度的区域划分为簇,并在有噪声的数据中发现任意形状的簇,在此算法中将簇定义为密度相连的点的最大集合。算法中两个重要参数：距离阈值和数量阈值(minpoints)。通过这两个参数，可以筛选出告警组，即告警组内满足距离阈值的链路告警信息的数量大于数量阈值。
请参见图4，图4示出了上述步骤S3000的另一实施例的具体实现过程示意图。如图 4所示，步骤S3000至少包括以下步骤：
S3100，以时间间隔作为样本距离，对告警集合进行聚类处理，其中，时间间隔等于上报时间与当前时间之差。
可以理解的是，按照时间间隔作为样本距离，把告警集合分割成不同的告警组，使得同一个告警组内的链路告警信息的上报时间尽可能接近，同时，不在同一个告警组内的链路告警信息的上报时间的差距尽可能大。
S3200，汇集样本距离小于等于预设的距离阈值的链路告警信息，生成多个告警组。
可以理解的是，通过预设距离阈值，能将样本距离小于等于距离阈值的链路告警信息进行汇集归类，组成告警组。示例性的，如图5所示，本申请实施例中，网元A分别在t1、t1+1、t1+2、t1+3、t2时刻(单位为s)上报了下辖不同RRU的链路告警信息alm1、alm2、alm3、alm4和alm5，其中t2>t1+4，预设的距离阈值为1S。因此，alm1、alm2、alm3和alm4的时间间隔满足小于等于预设的距离阈值的条件，而alm5的时间间隔大于预设的距离阈值，由此得到告警组{alm1，alm2，alm3，alm4}。
S3300，获取告警组内链路告警信息的数量。
可以理解的是，在生成多个告警组后，通过指令统计告警组内链路告警信息的数量，以便于网管服务器判断链路告警信息的数量是否满足样本距离内链路告警信息的数量大于等于minpoints的链路告警信息，即聚类分析中的核心对象。
S3400，在链路告警信息的数量小于预设的数量阈值的情况下，去除告警组。
可以理解的是，在链路告警信息的数量小于预设的数量阈值的情况下，由于该告警组与核心对象的告警组内，且不属于核心对象，故需要把该告警组视为聚类分析中的噪声点，并对其进行去除处理。示例性的，预设的数量阈值取值为2，则在链路告警信息的数量小于2的情况下，去除该告警组。上述步骤中获取的告警组{alm1，alm2，alm3，alm4}，链路告警信息的数量为4，大于数量阈值，则该告警组予以保留。
可以理解的是，上述步骤S3100至S3400，等效于在密度聚类分析中设置邻域参数(e＝1,minPts＝2)，其中，e为距离阈值，minPts为数量阈值。
S4000，根据波长信息，将告警组内的射频单元和与射频单元相连的基带单元分入同一个波分设备组。
可以理解的是，由上述步骤的聚类分析后获取的告警组，其链路告警信息所对应的射频单元、与射频单元相连的基带单元大概率连接到同一套波分设备上。为确保射频单元、射频单元连接到同一波分设备，需要通过分析射频单元的光模块与射频单元的光模块的主 波长，判断是否满足波分设备的光模块波长规范。
请参见图6，图6示出了上述步骤S4000的另一实施例的具体实现过程示意图。如图6所示，步骤S4000至少包括以下步骤：
S4100，根据射频单元和基带单元的连接关系，确定与告警组内的射频单元相连的基带单元。
可以理解的是，由射频单元采集的数据信息通过光纤和波分设备传送到基带单元，因此，射频单元和基带单元的连接关系能通过网管服务器的数据配置获得。通过获取告警组，能确定与链路告警信息对应的射频单元，以及与告警组内的射频单元相连的基带单元。应该理解的是，网管服务器通过射频单元和基带单元之间配置管理，获取射频单元和基带单元的连接关系属于现有技术，此处不再赘述。
S4200，匹配基带单元和射频单元的波长信息。
可以理解的是，由上述步骤S1000获取了多个基带单元和射频单元的波长信息，并且，波长信息包括基带单元和射频单元之间光模块的主波长。因此，在获取告警组内对应的基带单元和射频单元后，能通过网元ID进行匹配，获取告警组内基带单元和射频单元之间光模块的主波长。其中，基带单元和射频单元的波长信息的匹配操作由网管服务器完成，同样属于现有技术，此处不再赘述。
S4300，在基带单元和射频单元的波长信息的差值位于预设的波长范围的情况下，将射频单元和基带单元分入同一个波分设备组。
可以理解的是，在获取基带单元和射频单元的波长信息后，需要判断基带单元和射频单元之间光模块的主波长是否满足波分设备的光模块波长规范，进而对告警组内的基带单元和射频单元进行分组处理。
请参见图7，图7示出了上述步骤S4300的另一实施例的具体实现过程示意图。如图7所示，步骤S4300至少包括以下步骤：
S4310，根据波长信息对告警组内射频单元的端口和基带单元的端口进行排序，得到端口排序集合。
可以理解的是，由上述步骤S4200获得与基带单元和射频单元匹配的波长信息后，并根据光模块的主波长的大小对射频单元的端口和基带单元的端口进行排序。示例性的，端口排序集合如下表1所示。如表1可见，按照光模块的主波长递增的顺序，对射频单元的端口和基带单元的端口进行排序，以便于对光模块的主波长进行统计和计算。
表1：端口排序集合表
S4320，计算端口排序集合内的任意相邻端口之间的波长信息的差值。
可以理解的是，在获取端口排序集合后，计算任意相邻端口之间的波长信息的差值，就能确定光模块的主波长是否满足波分设备的光模块波长规范。可以理解的是，波分设备对光模块波长有严格的规范和要求，相邻端口之间的波长信息的差值必须相等，以免影响波分设备的数据配置和数据传送。
S4330，在各个波长信息的差值位于预设的波长范围的情况下，将射频单元和基带单元分入同一个波分设备组。
可以理解的是，在各个波长信息的差值位于预设的波长范围的情况下，则射频单元的端口和基带单元的端口的主波长呈递增或者递减排列，符合波分设备的光模块波长规范。示例性的，各个波长信息的差值位于预设的波长范围，能进一步限定为各个波长信息的差值均为20nm，如表1所示的射频单元的端口和基带单元的端口的波长信息的差值均为20nm，则可将射频单元和基带单元分入同一个波分设备组。
可以理解的是，将符合条件的射频单元和基带单元分入同一个波分设备组，准确地识别出拓扑组网，然后直接按照网元ID把射频单元和基带单元存入数据库，以便于网管服务器对拓扑组网数据进行调用和修改。
可以理解的是，本申请涉及的波分设备不限于6波的CWDM波分设备，还可以是12波的CWDM波分设备、18波的CWDM波分设备，还可以是其它波分设备，如密集型光波复用(Dense Wavelength Division Multiplexing，DWDM)波分设备、细波分复用(Lan Wavelength Division Multiplexing，LWDM)波分设备等。
请参见图8，图8示出了上述步骤S4000的另一实施例的具体实现过程示意图。如图8所示，步骤S4000至少包括以下步骤：
S4400，在射频单元的链路告警信息新增的情况下，根据射频单元定位到与之对应的波分设备组。
可以理解的是，由上述步骤S4300把符合条件的射频单元和基带单元分入同一个波分设备组后，当射频单元新增链路告警信息，能通过射频单元的ID和RRU的端口识别号快速定位到对应的波分设备组，以保证射频单元的链路告警信息的定位精准性。可以理解的是，网管服务器通过获取射频单元的新增链路告警信息，并获取射频单元的信息，属于现有技术，此处不再赘述。
S4500，在波分设备组内射频单元的所有端口均存在链路告警信息的情况下，判定射频单元与基带单元之间的波分设备或波分设备之间的主干光纤发生故障。
可以理解的是，网管服务器在定位到链路告警信息对应的波分设备组后，能获取波分设备组内射频单元的其余端口的链路告警信息信息。在波分设备组内射频单元的所有端口均存在链路告警信息的情况下，则能判断出射频单元与基带单元之间链路出现故障，进而快速定位出故障点为射频单元与基带单元之间的波分设备或波分设备之间的主干光纤，提高了故障分析的效率和定位精准性。
本申请实施例通过获取多个基带单元和射频单元的波长信息，其中，波长信息包括基带单元和射频单元之间光模块的主波长；采集射频单元的链路告警信息，得到告警集合；聚类处理告警集合，得到多个告警组；根据波长信息，将告警组内的射频单元和与射频单元相连的基带单元分入同一个波分设备组，能够快速准确地识别出无线接入网的拓扑组网，便于对新增故障进行快速精准的分析和定位，提高了拓扑组网识别的准确性和网络单元的维护便利性。
