控制无源光网络中光网络单元的管理方式的方法和装置 技术领域
本申请涉及但不限于通信领域。
背景技术
无源光网络(PON,Passive Optical Network)是千兆带宽级别的宽带无源光网络技术，目前得到大规模商用的主要是以太网无源光网络(EPON)和吉比特无源光网络(G-PON,Gigabit-capable Passive Optical Network)技术。PON网络由光线路终端(OLT，Optical Line Terminal)，无源光分配网(ODN，Optical Distribution Network)和光网络单元(ONU，Optical Network Unit)组成。与传统的接入网技术及以太网交换机技术相比，PON采用自动拓扑发现机制，其终端设备ONU具有自动注册功能，可以动态的注册及去注册。在PON网络上开通业务需要对OLT和ONU做配置操作。目前对OLT的管理方式主要是命令行CLI和SNMP两种管理方式，而且这两种方式都是受运营商控制的。但对ONU则存在多种不同的管理方式，不同形态的ONU，其能支持的管理方式也不同。比如对于FTTH的ONU，目前主要存在两种形态:SFU和HGU。目前主流的SFU都支持远程管理方式、Telnet管理方式和WEB管理方式，而主流的HGU都支持远程管理方式、远程管理和TR069混合方式、Telnet方式和WEB方式。

本发明提供的方法实施例，在ONU有多种管理方式共存的情况下，设置管理方式的优先级，解决了相关技术中网上ONU因多种管理方式同时进行导致的配置冲突问题，该方法控制灵活，实现简单，提高了PON网络ONU设备的可维护性。
下面对本发明提供的方法实施例作进一步说明：
图3为本发明实施例提供的无源光网络的示意图。图3所示网络包括EMS(Element Management System，网元管理系统)100、OLT200、ODN300、ONU400，其中：
EMS100，设置为：对OLT200、ONU400以及xPON网络的配置、管理以及维护等工作，本发明实施例中可用于控制并在OLT上生成对于ONU的配置管理方式的优先级列表，同时根据配置管理方式完成对ONU本地数据的配置与管理；
OLT200，设置为：启动ONU的发现过程，完成ONU在OLT上注册与 认证，建立与ONU之间的内部远程管理通道。并根据EMS100、其他运维系统或配置管理方式生成ONU管理配置方式的类型与优先级列表，并可完成ONU管理配置方式类型与优先级的修改与更新。
在ONU完成注册认证，且内部远程管理通道建立成功后，由OLT通过内部远程管理通道完成配置管理方式类型与优先级的下发，并在OLT生成维护的配置管理方式的类型与优先级发生变化时，重新下发给ONU。同时接收ONU对下发结果的反馈，并可以根据一定的策略进行自动处理或执行其他的处理方式。
OLT根据网管、其他运维系统或配置方式通过OLT与ONU之间远程管理通道完成对配置管理方式的锁定。
ODN300，设置为：在OLT200下连接数量不等的ONU400，作为OLT200和ONU400之间直接的物理连接通道，可能由多个物理器件组合而成；
ONU400，设置为：实现用户业务的最终接入，接受OLT200的管理，并根据OLT的指令进行响应。
ONU默认生成并维护其本地的配置管理方式类型与优先级列表以及本地默认锁定的配置管理方式，并在ONU完成认证后根据本身能力保持与OLT下发的配置管理方式类型与优先级的一致。且根据OLT的指令完成锁定方式的切换，并在与OLT之间的管理通道中断后，将配置管理方式重新切换为ONU本地WEB方式。
在上述网络中，通过上述信息交互，可以有效控制ONU上管理方式的变更，减少配置冲突的发生，提高设备的可维护性。
为了保证ONU和OLT上管理方式的配置的一致性，所述ONU接收OLT为所述ONU设置的所述管理方式以及所述管理方式在所述ONU上对应的优先级信息，还可包括：
当OLT设置的管理方式包括ONU不支持的管理方式，则向所述OLT发送失败消息，其中所述失败消息包括在所述OLT设置的管理方式中所述ONU不支持的管理方式；
当OLT设置的管理方式未包括ONU支持的一个或多个管理方式时，所述ONU关闭所述ONU支持的管理方式中所述OLT设置的管理方式中不包括的管理方式。
ONU根据OLT指示对配置管理方式类型进行更新，当OLT下发配置管理类型多于ONU实际支持且本地默认配置的管理类型时，应返回失败同时在配置管理方式优先级处理中忽略此配置管理类型，并通知OLT，后续由OLT进行相应的配置管理类型的处理。当OLT下发配置管理类型少于ONU实际支持且本地配置的管理类型时，ONU应更新其本地配置管理方式，并按OLT下发的管理配置方式工作，且关闭其余的配置管理方式。
由上可以看出，当OLT设置的管理方式与ONU支持的管理方式不一致时，通过ONU对管理方式的控制，如发送失败消息或关闭一种或多种管理方式，从而保证OLT设置的管理方式与ONU支持的管理方式一致，减少配置信息记录不一致问题的出现。
其中，所述ONU根据所述管理方式以及所述管理方式在所述ONU上对应的优先级信息，控制是否更改当前使用的管理方式，包括：
从所述管理方式以及所述管理方式在所述ONU上对应的优先级信息中，查找所述配置请求中的管理方式在所述ONU上对应的优先级；
如果查找到所述配置请求中的管理方式的优先级，则判断配置请求中的管理方式的优先级是否高于当前使用的管理方式的优先级；
如果配置请求中的管理方式的优先级高于当前使用的管理方式的优先级，则更改当前的管理方式；如果配置请求中的管理方式的优先级低于或等于当前使用的管理方式的优先级，则不更改当前的管理方式。
当其他管理方式在ONU终端上的优先级高于ONU当前锁定的管理方式的优先级时，该管理方式可以修改ONU上的锁定管理方式，之后可以对ONU进行配置操作；当其他管理方式在ONU终端上的优先级低于ONU终端当前锁定的管理方式优先级时，该管理方式无法对ONU进行配置操作，且不能修改ONU上的锁定管理方式。
由上可以看出，通过比较管理方式的优先级，确定是否更改管理方式， 从而减少管理方式冲突的出现，实现简单方便。
另外，为了降低恶意更改管理方式或误操作更改管理方式的出现，与相关技术通过账户和密码的身份认证机制来更改相比，本发明实施例提出新的更改方式，说明如下：
OLT接收更改管理方式的配置请求，并将所述更改管理方式的配置请求发送给所述ONU。
由于OLT是由运营商控制的，减低了普通用户访问并对其进行配置操作，从而避免了恶意或非恶意的误操作影响正常业务的情况的出现。
下面以一个应用实例作上述说明作以说明：
图4为本发明实施例提供的控制无源光网络中光网络单元的管理方式的方法的应用实例的流程示意图。图4所示流程包括如下步骤：
S401：在OLT上通过命令行针对不同ONU终端类型配置ONU管理方式的类型与优先级。管理类型包括不限于OLT控制的远程管理方式、TR069方式、简单网络管理协议(SNMP，Simple Network Management Protocol)方式、远程登录(Telnet)方式、本地网页(WEB)方式等；其中远程管理方式可以为扩展操作、管理、维护(OAM，Operation Administration and Maintenance)、光网络单元管理控制接口(OMCI，ONU Management and Control Interface)或其他OLT与ONU之间的远程管理方式；
不同配置方式默认优先级如下：OLT控制的远程管理方式(通过扩展OAM或OMCI)优先级最高，其次是远程管理和TR069混合方式，再次是TR069管理方式，再次是Telnet管理方式，本地WEB管理方式优先级最低。
高优先级管理方式可以锁定自己及下一级管理方式为ONU当前锁定管理方式，反之低优先级管理方式不能锁定自己和上一级配置管理方式，当针对不同类型ONU终端的管理方式在其默认优先级类型中不存在，则应对其忽略；
S402：ONU上维护一个配置管理方式类型与优先级列表，该配置管理方式类型默认包含本ONU终端可以支持的所有配置管理方式，并必须包含其优先级列表中的最高优先级管理方式以及本地WEB方式。
其配置管理方式除了最高优先级管理方式为OLT控制的远程管理方式不能修改之外，其他管理方式的优先级可以修改。此外，ONU上还通过一个控制开关来控制当前锁定的管理方式，只有锁定的管理方式可以进行配置操作，其他非锁定状态的管理方式不允许做配置操作。查询操作不受优先级和锁定限制。其他非锁定状态的管理方式可以在锁定管理方式的优先级低于自身优先级的情况下修改当前锁定的管理方式，之后才可以对ONU进行配置操作。当前锁定管理方式可通过多种管理方式查询；
S403：ONU加电启动后，在与OLT成功建立远程管理通道之前，其默认的管理方式优先级与OLT保持一致，为：OLT控制的远程管理方式(通过扩展OAM或OMCI)优先级最高，其次是远程管理和TR069混合方式，再次是TR069管理方式，再次是Telnet管理方式，WEB管理方式优先级最低。但ONU默认的锁定管理方式为WEB管理方式；
S404：当ONU与OLT成功建立远程管理通道后，OLT下发ONU管理方式类型与优先级。
举例来说，ONU切换锁定管理方式：SFU切换为远程管理方式，HGU切换为远程管理+TR069混合方式，其中远程管理方式用于PON链路相关参数的配置管理，TR069用于用户侧端口及业务的管理。此时ONU禁止其他管理方式对其进行配置操作，只允许进行查询操作；
S405：当用户通过OLT修改ONU的锁定管理方式时，OLT通过远程管理通道下发配置给ONU，ONU锁定该管理方式，且不允许其他管理方式对ONU进行配置管理，只允许进行查询操作；
S406：当其他管理方式在ONU终端上的优先级高于ONU当前锁定的管理方式优先级时，该管理方式可以修改ONU上的锁定管理方式，之后可以对ONU进行配置操作；
当其他管理方式在ONU终端上的优先级低于ONU终端当前锁定的管理方式优先级时，该管理方式无法对ONU进行配置操作，且不能修改ONU上的锁定管理方式。
S407：当ONU与OLT之间的管理通道中断后，ONU自动切换其锁定管 理方式为WEB管理方式；
在ONU与OLT之间的管理通道恢复后，重新接受OLT下发的配置管理方式类型与优先级，并根据OLT要求完成配置管理方式的锁定。
本发明提供的应用实例，在ONU有多种管理方式共存的情况下，设置管理方式的优先级，解决了相关技术中网上ONU因多种管理方式同时进行导致的配置冲突问题，该方法控制灵活，实现简单，提高了PON网络ONU设备的可维护性。
