Reliable and high-quality service transmission, charging system, signaling system, handover between base stations, roaming, etc. all require precise synchronization control. Synchronization is divided into clock synchronization and time synchronization. To ensure the normal operation of the service and performance requirements, the communication network and synchronization-related devices need to access the clock synchronization network and the time synchronization network.

本申请主张在2017年6月2日在中国提交的中国专利申请号No.201710409002.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及无线通信技术领域，尤其涉及一种同步网络告警方法和装置。
背景技术
本部分旨在为权利要求书中陈述的本公开的实施方式提供背景或上下文。此处的描述不因为包括在本部分中就承认是现有技术。
同步网是通信网的一个必不可少的重要组成部分，可靠高质量的业务传输、计费系统、信令系统、基站之间的切换、漫游等均需要精确的同步控制。同步分为时钟同步和时间同步，为保证业务正常运行和性能指标要求，通信网络与同步相关的设备需要接入时钟同步网和时间同步网运行。同步网在上游安装同步源服务器，通过传输网络将同步信息逐级传递给需要同步的设备，比如基站等。
同步网是网络正常运行的关键，同步网故障将直接影响通信业务。因此，同步网中的同步节点设备不能正常同步运行时，比如同步锁相环出现故障，无法锁定时，会产生同步失锁告警，以便于管理系统可以获知同步网发生的故障，及时处理。
相关技术中，同步节点设备在无法正常收到同步报文或者无法正常运行在同步状态时会产生故障告警，比如产生同步失锁告警、同步报文丢失告警等。但是，除了设备无法同步这种明显的故障情况，还有一些异常情况是虽然同步节点设备可以同步于上游同步源设备，但是实际传递的同步信号质量已经下降。
例如，传输设备一般使用三级节点以下时钟，时钟精度为4.6ppm(百万分之一)。传输设备在跟踪质量正常的同步源情况下，其精度优于3*10 -12，如果传输设备跟踪的同步源质量下降，则其精度介于3*10 -12和内部时钟的4.6ppm之间。而业务对时钟的需求高于内部时钟的4.6ppm，比如基站通信业务对时钟的要求是0.05ppm。那么意味着，传输设备正在跟踪同步源，而同步源的质量下降，有可能使得传输设备跟踪之后的同步精度低于业务需求，进而影响业务。同步质量下降这种情况相关技术不会产生告警或提示信息，往往只有当下游依靠同步的业务质量已经受到影响一段时间后，经过故障排查才会发现同步质量的下降，影响到了业务感知和故障定位速度。

具体实施方式
为了减少由于同步网络质量下降而导致的通信网络服务质量下降，本公开实施例提供了一种同步网络告警方法和装置，用以针对同步网络质量下降及时进行告警，提高同步网络可靠性，保证通信网络服务质量。
以下结合说明书附图对本公开的可选实施例进行说明，应当理解，此处所描述的可选实施例仅用于说明和解释本公开，并不用于限定本公开，并且在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。
实施例一
发明人发现，在同步网络质量下降时，同步节点设备不会进行告警。例如，TD-SCDMA/TD-LTE基站要求基站的时间同步精度为1.5us，如果基站之间的时间误差超过这个限值，则相邻基站空口会产生时隙间干扰和上下行时隙干扰，导致用户通话不成功。为了避免这种情况，TD-SCDMA/TD-LTE基站有退服机制，如果基站失去时间源则该基站在一定时间内将退出服务，以免对其他相邻基站造成干扰。但是，当基站通过传输网络获取同步信息时，在相关技术中同步告警机制下，只有当基站发现丢失时间源时才会产生告警，如果基站能够从传输网获得时间，但是时间精度超过限值，基站不会产生告 警，仍然会继续跟踪，对业务造成影响，而维护人员由于无法获知同步源质量下降的告警信息，无法准确判断影响业务质量的根源，需要耗费大量人力进行故障定位。
有鉴于此，本公开实施例提供了一种同步网络告警方法，同步节点设备对跟踪的同步源的质量等级进行监测，在发现同步源的质量等级低于预设质量等级阈值时即进行告警，以避免由于同源质量等级下降导致的通信网络服务质量下降，提高同步网络的可靠性，保证通信网络的服务质量。
如图1所示，其为本公开实施例提供的同步网络告警方法的实施流程示意图，可以包括以下步骤：
S11、获取跟踪的同步源的质量等级信息。
S12、如果根据所述质量等级信息判断出所述同步源的同步质量等级低于预设的质量等级阈值则进行告警。
具体实施时，步骤S11中，同步节点设备可以按照任一方式获取跟踪的同步源的质量等级信息：
方式一、从接收到的同步源报文中获取
这种实施方式中，步骤S11可以按照图2所示的流程实施：
S21、接收跟踪的同步源发送的同步源报文，所述同步源报文中携带有所述同步源的质量等级信息。
步骤S22、从所述同步源报文中获取跟踪的同步源的质量等级信息。
其中，同步源包括频率同步源或者时间同步源。对于频率同步源，质量等级信息包括SSM(Synchronization Status Message，同步状态信息)。如表1所示，其给出了一种可能的SSM的编码和定义。
表1
序号 SSM编码 同步质量等级
0 0000 质量未知
1 0001 预留
2 0010 基准钟
3 0011 预留
4 0100 2级节点时钟SSU_A
5 0101 预留
6 0110 预留
7 0111 预留
8 1000 3级节点时钟SSU_B
9 1001 预留
10 1010 预留
11 1011 承载设备时钟
12 1100 预留
13 1101 预留
14 1110 预留
15 1111 不可用
同步节点设备获取频率同步源携带的该SSM编码时，例如通过ESMC(以太网同步消息通道)报文提取携带的SSM编码。假设预设的质量等级阈值为SSU_A，则当同步源的质量等级高于等于SSU_A时，同步节点设备不会产生告警；当同步源的质量等级为SSU_B时(根据表1，此时对应的SSM编码为1000)，则同步节点设备产生相应告警。
对于时间同步源，可以通过PTP(精确时钟同步协议)获取时间源，质量等级信息可以包括PTP携带的clockClass、Accuracy、OffsetScaledLogVariance的其中一种或几种的综合。
例如，以PTP携带的clockClass作为告警的质量等级，clockClass取值从0到255，数值越小，质量等级越高。假设设定质量等级阈值为clockClass＝6，则当PTP源的质量等级高于等于clockClass 6时(即clockClass的具体数值<＝6),设备不会产生告警；当PTP源的质量等级clockClass＝7时，则设备产生相应告警。其中，clockClass指时钟来源级别，其定义了时钟设备时钟来源的级别，即质量等级；Accuracy指时钟精准度，其定义时钟设备的精准度；OffsetScaledLogVariance指时钟稳定度，其定义了时钟设备的稳定度，是节点本身使用Allan偏差计算出它所接收时钟质量的评估。
以PTP携带的clockClass和Accuracy的综合指标作为告警的质量等级为 例，假设预设的质量等级阈值为clockClass＝6，Accuracy为100纳秒，当同步源的质量等级clockClass低于6(例如为7)而且Accuracy数值代表大于100纳秒时，则同步节点设备产生告警。
方式二、从1PPS+TOD(1Palse per Second Time of Day，秒脉冲日时间)接口获取跟踪的时间同步源。
这种实施方式中，质量等级信息指该接口携带的相应地质量等级信息，如TOD中携带的秒脉冲信号信息。
基于此，本公开实施例中，可以按照图3所示的流程获取跟踪的同步源的质量等级信息：
S31、从1PPS+TOD接口获取跟踪的时间同步源。
S32、从日时间TOD中获取携带的秒脉冲信号信息。
实施例二
具体实施时，为了避免由于个别质量等级报文错误导致的误告警，在步骤S11中，如果根据质量等级信息判断出跟踪的同步源的同步质量等级低于预设的质量等级阈值后，在进行告警之前，还包括以下步骤：确定跟踪的同步源的同步质量等级低于所述质量等级阈值的持续时长达到第一预设时长。
具体实施时，同步节点设备在检测到跟踪的同步源的质量等级低于质量等级阈值达到一定时间(如M秒)之后才上报告警。这样可以避免由于个别质量等级报文错误引发误报警，而且，可以避免在正常的同步源倒换期间产生告警。假设同步源节点设备可以接收到同步源A和同步源B发送的同步源报文，同步节点设备选定跟踪同步源A，当同步源A的质量等级下降时，同步节点设备倒换至跟踪同步源B，这样，如果设置检测同步源的质量等级低于质量等级阈值达到一定时长才上报告警时，在这段时间M秒内，同步节点设备已经从同步源A倒换到了同步源B，如果同步源B的质量等级为正常，则质量等级信息也从同步源A的下降倒换到了同步源B的正常等级，这样同步节点设备在倒换期间就不会上报告警。这样，只要管理系统接收到告警，均表示同步节点设备当前的同步源质量下降，且没有正常的同步源可倒换的情况，即需要维护人员处理的情况。如果设备有正常的同步源可以倒换跟踪，则不会产生告警。
本公开实施例中，同步节点设备在进行告警之后，如果检测到跟踪的同步源的同步质量等级高于预设的质量等级阈值时，消除告警。可选地，具体实施时，同步节点设备还可以在消除告警之前，确定同步源的同步质量等级高于所述质量等级阈值的持续时长达到第二预设时长，例如，第二预设时长可以设置为N秒。这样，可以避免不稳定的状态恢复，导致反复告警的问题。
需要说明的是，具体实施时，可以预先设置同步源的质量等级阈值，对于同一同步网络中的设备，可以设定相同的阈值，也可以设定不同的阈值。
可选地，具体实施时，在步骤S11中，如果根据所述质量等级信息判断出所述同步源的同步质量等级低于预设的质量等级阈值，则在进行告警之前，还包括以下步骤：
步骤一、获取跟踪的同步源距离根同步源的同步跳数信息；以及
步骤二、确定所述同步跳数信息小于等于预设的同步跳数阈值。
其中，根同步源指同步跟踪路径的顶端，一般由同步服务器提供，在PTP同步协议中，为GM(GrandMaster，超级主时钟)设备。
基于此，同步节点设备可以通过同时检测跟踪的同步源携带的同步跳数信息和质量等级信息，作为产生告警的条件。这样可以限定同步网络中产生告警的同步节点设备范围，例如限定在距离根同步源一定跳数以内的设备才产生告警。例如，设定当前选用PTP参考源的clockClass低于某个质量等级阈值，且其携带的同步跳数值stepsRemoved值为0时才产生告警，则网络中只有和GM设备相连的设备(其stepsRemoved值为0)才可能产生该告警，网络再下游的设备则不会产生告警。避免在同一同步网络中不同设备产生大量相同原因的告警，且通过这种方式，可以自动确定根源告警所在位置，因为跳数为0的设备即为同步跟踪路径最上游的设备。
如图4所示，NE1到NE8组成同步网络，跟踪路径为NE1->NE2->NE3->NE4->NE5和NE1->NE2->NE6->NE7->NE8，根据跟踪路径节点跳数，每个网元收到的参考源携带的stepRemoved值均不相同。当NE1参考源质量等级下降，且NE1为第一个跟踪节点(stepRemoved＝0),只有NE1产生了告警，这个告警代表了在同步源质量下降时整个同步链上的首个下降节点信息。
本公开实施例中，同步节点设备除了对选定跟踪的同步源的质量等级进行检测以外，还可以对同步源列表中其它同步源的质量等级进行检测，以及在检测到其它跟踪源的质量等级低于预设的质量等级阈值时，也可以进行告警。基于此，本公开实施例中，同步节点设备还可以获取同步源列表中除跟踪的同步源以外的其他同步源的质量等级信息；以及如果根据获取的质量等级信息判断出其它同步源的同步质量等级低于所述质量等级阈值则进行告警。
例如，同步节点设备对根据优先级列表选出的某个频率源进行跟踪，并监测其SSM质量等级信息，在其SSM值低于阈值时产生告警。进一步地，同步节点设备也可以对处于同步源列表中的其他同步源的质量等级下降时产生告警。例如，在频率源列表中包括3个可以选择的频率同步源，当同步节点设备跟踪第一优先级的频率同步源时，也可以对处于频率优先级列表中第二优先级的频率同步源的SSM质量等级信息进行监测，在其SSM值低于阈值时产生告警。
可选地，具体实施时，可以设置处于同步源列表中的其它同步源的质量等级信息下降时产生的告警级别，其告警级别低于同步节点设备正在跟踪的同步源的质量等级下降的告警级别。例如，处于同步源列表中的其它同步源的质量等级下降时产生次要告警，而同步节点设备正在跟踪的同步源的质量等级下降时产生重要告警。
具体实施时，针对同步源列表中其它同步源的质量等级监测与跟踪的同步源的质量等级监测过程类似，例如，在监测到其它同步源的质量等级低于预设的质量等级阈值达到第一预设时长后，同步节点设备进行告警；如果在监测到其它同步源的质量等级高于等于预设的质量等级阈值达到第二预设时长后，同步节点设备消除告警。
本公开实施例提供的同步网络告警方法中，同步节点设备在判断出同步源的同步质量等级下降时，产生相应的告警，而且，同步节点设备可以只对目前跟踪的同步源的质量等级进行告警，该质量等级直接反映了设备当前跟踪的同步源的质量，便于管理系统掌握目前的同步网络质量。另外，还可以通过设定质量等级的检测结果达到一定时间才产生告警和消除告警，可以保证告警的有效性和稳定性。
基于同一发明构思，本公开实施例中还提供了一种同步网络告警装置，由于上述装置解决问题的原理与同步网络告警方法相似，因此上述装置的实施可以参见方法的实施，重复之处不再赘述。
