Description

光网络单元ONU掉电告警信息的处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种光网络单元ONU掉电告警信息的处理方法及装置。
背景技术
随着光网络的不断发展以及各个国家宽带战略的实施，光纤接入FTTX(Fiber-to-the x，x＝H for home，Pforpremises C for curb and N for node or neighborhood)其中FTTH光纤到户，FTTP光纤到驻地，FTTC光纤到路边/小区，FTTN光纤到结点，已经全面铺开，其终端产品光网络单元(Optical Network Unit，简称为ONU)也得到了广泛的应用。为了便于局方远程维护ONU的各类信息，ONU需要在不同的场景中，实时地向局端设备光线路终端(Optical Line Terminal，简称为OLT)上告各类告警消息，掉电告警就属于其中一类消息之一。
该功能的原理是ONU在掉电的过程中，系统检测到电压低于某一个规定的阀值范围时，需要在掉电保持的时间段内实时地向OLT发送一个掉电告警，告知OLT自己处于掉电关闭状态。
该功能的目的主要是向局端设备OLT指示ONU的当前断电状态，与断纤等状态区分开，方便工程上的维护和状态的查看。该功能也在实际使用中得到了广泛的应用，但是该功能在标准上仅仅考虑了理论上的情况，并没有考虑到实际使用过程中的一些情况，导致了下面一些问题：
1、由于实际使用中电压等一些问题，导致ONU实际电压在较短时间内触发了掉电告警，后面又恢复了，导致ONU上报了掉电告警，但是ONU真实状态却是在线的；
2、由于实际使用中电压等一些问题，导致ONU实际电压在较短时间内触发了掉电告警，后面恢复后，使得ONU某些器件工作不正常，处于不正常工作状态；
3、由于实际使用中电压等一些问题，导致ONU实际电压在一段时间内触发了掉电告警，使得ONU在该段时间内持续发送掉电告警，对局端设备(OLT)产生了大量的冲击。
针对相关技术中在ONU上报掉电告警信息时，仅仅考虑了理论上的情况，并没有考虑到实际使用过程中的一些情况导致误上报掉电告警信息的问题，目前 尚未提出有效的解决方案。

具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本实施例提供了一种光网络单元ONU掉电告警信息的处理方法，图1是根 据本发明实施例的光网络单元ONU掉电告警信息的处理方法的流程图，如图1所示，该方法的步骤包括：
步骤S102：在检测到ONU产生掉电告警信息时，将所述掉电告警信息写入所述ONU的缓存中；
步骤S104：将满足预设条件的所述ONU缓存中的掉电告警信息上报到光线路终端OLT；
步骤S106：触发禁止执行所述ONU发送使能的操作，和/或对所述ONU进行复位。
通过本实施例中的步骤S102步骤S106，采用将满足预设条件的所述ONU缓存中的掉电告警信息上报到光线路终端OLT，即通过满足预定条件的掉电告警信息确定ONU已经极有可能处于真正的掉电状态，再触发禁止执行所述ONU发送使能的操作，以保证可OLT在收到掉电告警信息之后不会检测到ONU还处于在线状态，和/或对所述ONU进行复位，通过对ONU进行复位可以保证假的掉电对于ONU产生的影响导致工作不正常，并且可以保证ONU后续所有器件正常工作，并和OLT注册状态进行同步，避免ONU和OLT上状态不一致，从而解决了相关技术中在ONU上报掉电告警信息时，仅仅考虑了理论上的情况，并没有考虑到实际使用过程中的一些情况导致误上报掉电告警信息的问题。
对于本实施例中涉及到的将满足预设条件的所述ONU缓存中的掉电告警信息上报到光线路终端OLT的方式，在本实施例的可选实施方式中可以通过如下方式来实现：
方式一：在所述ONU缓存中的掉电告警信息的数量大于或等于预设阈值时，上报所述掉电告警信息到光线路终端OLT；
方式二：在到达预设时间时，上报所述掉电告警信息到光线路终端OLT。
而在本实施例的步骤S104将满足预设条件的所述ONU缓存中的掉电告警信息上报到光线路终端OLT之后，本实施例的方法还可以包括：关闭对所述掉电告警信息进行检测的操作。
通过关闭对所述掉电告警信息进行检测的操作，可以避免掉电告警检测模块持续检测到掉电告警，从而对OLT设备产生冲击。
而在本实施例的步骤S1032将所述掉电告警信息写入所述ONU的缓存中之前，本实施例的方法还可以包括：通过预设规则检测所述ONU是否为掉电告警状态。其中，该所述预设规则包括：中断所述ONU的方式，当然该方法仅仅是本实施例中的可选实施方式，对于其他能够检测掉电告警状态的方式也是在本发明的保护范围之内。
在本实施例中还提供了一种光网络单元ONU掉电告警信息的处理装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图2是根据本发明实施例的光网络单元ONU掉电告警信息的处理装置结构框图，如图2所示，该装置包括：缓存模块22，设置为在检测到ONU产生掉电告警信息时，将所述掉电告警信息写入所述ONU的缓存中；上报模块24，与缓存模块22耦合连接，设置为将满足预设条件的所述ONU缓存中的掉电告警信息上报到光线路终端OLT；触发模块26，与上报模块24耦合连接，设置为触发禁止执行所述ONU发送使能的操作，和/或对所述ONU进行复位。
可选地，该上报模块24，还设置为在所述ONU缓存中的掉电告警信息的数量大于或等于预设阈值时，上报所述掉电告警信息到光线路终端OLT；和/或，在到达预设时间时，上报所述掉电告警信息到光线路终端OLT。
可选地，在将满足预设条件的所述ONU缓存中的掉电告警信息上报到光线路终端OLT之后，所述装置还包括：关闭模块，与上报模块24耦合连接，设置为关闭对所述掉电告警信息进行检测的操作。
可选地，在将所述掉电告警信息写入所述ONU的缓存中之前，所述装置还包括：检测模块，与缓存模块22耦合连接，设置为通过预设规则检测所述ONU是否为掉电告警状态。其中，该预设规则可以是：中断所述ONU的方式。
下面结合本发明的可选实施例对本发明进行举例说明；
本可选实施例提供了一种ONU掉电告警信息的处理方法，使得ONU不仅仅能够上报掉电告警功能，而且考虑到现网中实际的情况，保证ONU能够继续正常工作，并尽量减少对OLT的冲击。
图3是根据本发明可选实施例的ONU掉电告警信息的处理装置结构框图，如图3所示，该装置包括：掉电告警检测模块32，设置为掉电告警的检测，可以通过中断或者其它方式检测到该状态，一旦检测到该状态，需要将掉电告警相关信息写入到缓存中，等待OLT分配带宽上报，关闭告警检测功能并通知掉电告警反馈模块；
掉电告警反馈模块34，与掉电告警检测模块32耦合连接，由于FTTX系统是时分复用系统，并不是写入到ONU缓存中的掉电告警信息能够立即上报给OLT，需要等待OLT分配带宽(时隙)，所以为了保证掉电告警信息能够准确上报，需要对掉电告警进行检测，该模块用于将结果反馈给其它模块。
其中，对于掉电告警的检测有多种方法，可以使用计数的方式，每发送一次掉电告警计数一次，当到达相关标准定义的数量之后，就反馈给其它模块掉电告警发送完成；也可以使用定时的方式，针对FTTX系统的带宽分配的周期，保证设置的时间内能够完成相关告警的上报，当定时器到达之后，就反馈给其它模块掉电告警发送完成。
掉电告警保护模块36，与掉电告警反馈模块34耦合连接，设置为对掉电告警进行相关的保护操作，在收到掉电告警上报完成后，为了防止假的掉电(电压低或者其它情况导致检测到掉电告警)对于ONU和OLT的影响，掉电告警模块需要进行关闭ONU光模块发送使能以及复位操作。
其中，关闭ONU光模块发送使能可以保证OLT在收到掉电告警之后不会检测到ONU还处于在线状态，避免OLT认为ONU掉电告警是误报，从而忽略了本次掉电告警，并保证ONU后续不会持续发送掉电告警，避免对OLT产生冲击。
复位是为了保证在假的掉电对于ONU产生了影响导致工作不正常，并且可以保证ONU后续所有器件正常工作，并和OLT注册状态进行同步，避免ONU和OLT上状态不一致；如果是真实的掉电，复位也不会对ONU产生影响，因为此时已经断电了。
通过本可选实施例，在保证掉电告警正常上报的同时，通过相关操作，保证了掉电告警相关问题的解决，与相关技术的优势包括：
首先，掉电告警检测模块在检测到写入掉电告警之后，关闭掉电告警检测功能，避免掉电告警检测模块持续检测到掉电告警，从而对OLT设备产生冲击；
其次，掉电告警反馈模块保证了掉电告警已经送到了OLT设备，保证掉电告警真实上报，避免掉电告警模块的操作影响到掉电告警上报；
最后，掉电告警保护模块通过关闭光模块发送使能避免OLT对ONU掉电告警的误检测，也进一步保证ONU不会有其它消息冲击OLT；而复位操作保证了ONU器件工作正常和与OLT注册状态的同步性。
图4是根据本发明可选实施例的ONU掉电告警信息的处理方法流程图，如图4所示，该方法的步骤包括：
步骤S401：系统启动掉电告警检测功能，实时检测ONU掉电状态；
步骤S402：判断是否检测到掉电的状态，如果没有检测到继续检测，如果检测到进入步骤S403；
步骤S403：将掉电告警信息写入缓存，并关闭掉电告警检测功能；
步骤S404：通知掉电告警反馈模块，等待OLT分配带宽(时隙)上报告警；
步骤S405：判断掉电告警反馈模块检测掉电告警是否上报成功，如果上报成功进入步骤S406，否则继续检测；
步骤S406：通知掉电告警保护模块掉电告警上报成功；
步骤S407：掉电告警保护模块关闭ONU发送使能，保证ONU不会有其它消息发送；
步骤S408：掉电告警保护模块通知复位模块对ONU进行复位。
通过本可选实施例，使得ONU不仅仅能够上报掉电告警功能，而且考虑到现网中实际的情况，保证了ONU能够继续正常工作，并尽量减少对OLT的冲击。

工业实用性
在本发明中，采用将满足预设条件的所述ONU缓存中的掉电告警信息上报到光线路终端OLT，即通过满足预定条件的掉电告警信息确定ONU已经极有可能处于真正的掉电状态，再触发禁止执行所述ONU发送使能的操作，以保证可OLT在收到掉电告警信息之后不会检测到ONU还处于在线状态，和/或对所述ONU进行复位，通过对ONU进行复位可以保证假的掉电对于ONU产生的影响导致工作不正常，并且可以保证ONU后续所有器件正常工作，并和OLT注册状态进行同步，避免ONU和OLT上状态不一致，从而解决了相关技术中在ONU上报掉电告警信息时，仅仅考虑了理论上的情况，并没有考虑到实际使用过程中的一些情况导致误上报掉电告警信息的问题。
