Description

无源光纤网络PON中故障类别的确定方法及装置 技术领域
本发明涉及分通信领域，具体而言，涉及一种无源光纤网络(Passive Optical Network，简称为PON)中故障类别的确定方法及装置。
背景技术
网络服务保障系统提供故障诊断、告警处理、性能预警、评估优化、统计分析等众多实用功能，将宽带服务保障从人工、现场处理变为智能、远程处理，可服务于运维保障的各个环节，减低运维成本。而故障诊断功能作为其中一个重要组成部分，其准确性、快速性直接决定整个网络服务保障系统的影响力。
随着宽带增值类业务日益增多，PON网络快速部署，光路庞大。PON的光网络由无源器件组成，分分光器、光连接器和光缆等长期置于室外，而光缆又通常是长距离铺设，很容易受到外界环境的影响而发生故障，如连接器损坏，光纤弯曲和光纤折断等。光缆故障造成的业务中断占比高，其中大部分光缆故障是主干光纤断造成的。
当主干光纤断故障发生时，光纤线路终端(Optical Line Terminal，简称为OLT)PON口下所有光网络单元(Optical Network Unit，简称为ONU)都无法工作，导致所有ONU用户业务中断，该类型的故障优先级最高。故障处理中，第一步而且最关键的一步就是将准确判断故障类型，然后才是采取的措施。因此，作为一个稳定可靠的网络服务保障系统，必须要解决主干光纤断故障迅速判断问题，提高宽带服务保障的工作效率。
相关技术中，判断主干光纤断故障的方法通常是采用查询PON信号消失告警的方法。但这种方法存在以下局限性：当OLT PON口下所有ONU的光信号全部消失的时候，系统产生PON信号消失告警，但是ONU停电、分支光纤断和主干光纤断都会造成PON光信号消失。所以，产生PON信号消失告警不一定就是主干光纤断；
故障处理要求判断是线路故障还是设备故障。如果是线路故障，如主干光纤断，由线路维护部门负责；如果是设备故障，如ONU停电，由设备维护部门负责，各维护部门职责明确，如果网络服务保障系统不能准确判断PON信号消失告警的实际原因，出现误判，将ONU停电故障派发到线路维护部门而不是设备维护部门，将导致故障处理时间延长，降低宽带服务保障的工作效率。
针对相关技术中在PON发生故障时无法判断PON故障的类别的问题，目前尚未提出有效的解决方案。

本发明优选实施例的方法提供的判断主干光纤断的方法具有以下优点：
当系统产生PON信号丢失告警时，网络保障服务系统主干光纤判断方法对断电和断纤类型故障进行有效的区分，实现对故障精确分类。
主干光纤断故障派发到线路维护部门进行处理；ONU停电故障则派发到设备维护部门进行处理，实现不同故障不同维护部门分别负责，职责明确，降低了故障历时，提升了故障处理效率。
下面结合附图对本发明优选实施例的具体实施方式作进一步的详细描述。
图6是根据本发明优选实施例的PON信号丢失告警判断主干光纤断处理方法的流程图，如图6所示，本发明优选实施例的PON信号丢失告警消息的处理的步骤包括
步骤S602：PON信号丢失告警上报，即网络服务保障系统接收网元上报PON信号丢失告警；
步骤S604：获取PON口所有ONU状态，即网络服务保障系统获取该PON口所有的ONU状态，网络服务保障系统采用TL1接口与NMS(设备的网管系统，直接访问设备，获取线路的相关信息)对接，通过NMS的TL1接口可获取PON口下的所有ONU状态；
步骤S606：获取无断电、无分支光纤断告警的ONU数量，即通过查询当前告警表，去除存在掉电、分支光纤断的ONU，就是去除之前运行状态不正常的ONU，获取剩下无告警的ONU数量；
步骤S608：综合分析ONU状态进行故障分类判断，即综合分析剩下的无告警ONU数量和获取的ONU状态进行故障分类；
其中，无ONU断电、无分支光纤断告警的ONU数量为0，正常情况下一般不会出现，这种情况不做处理；
数量为1时，查看该ONU的状态是否掉电，是，认为ONU断电故障；否，则认为是分支光纤断；
数量为N时，查看无告警ONU中是否有掉电状态的ONU，有掉电状态的ONU，则认为PON口下所有ONU同时断电引起PON信号丢失；没有掉电状态的ONU，则认为是真实的主干光纤断；
步骤S610：主干光纤断属于线路故障，该类型的故障导致的后果是整个系统无法正常工作，该类故障的优先级最高；
步骤S612：对于主干光纤断线路故障，派发故障单到线路维护部门，线路维护部门负责在要求时限内修复故障；
步骤S614：ONU故障属于设备故障，如果ONU出现故障，将会影响该用户的所有业务，一般情况下不会对整个网络造成影响。其影响一般是个体的，少数的。相对于主干光纤断异常，该类故障的优先级较低。
步骤S616：对于ONU设备故障，派发故障单到设备维护部门，设备维护部门负责在要求时限内修复故障；
步骤S618：故障解决，即设备维护部门解决故障。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
工业实用性
本发明实施例提供的技术方案，可以应用于确定PON中的故障类别，采用接收无源光纤网络PON侧设备上报的所有光网络单元ONU的状态信息，所有ONU为PON侧设备所在PON下的ONU，其中，状态信息包括掉电状态、无掉电状态；从所有ONU中去除告警信息列表中存在指定告警信息记录的ONU，得到剩余ONU，其中，指定告警信息为断纤告警信息和断电告警信息；根据剩余ONU所对应的状态信息确定PON的故障类别。解决了现有技术中在PON发生故障时无法判断PON故障的类别的问题，提高了系统处理故障的效率。
