步骤 S302, 后台管理系统识别无源光网络中的 OLT和 OLT连接的 ONU, 并识别 ONU连接的 CBAT。 后台管理系统可以是 EMS或 NMS (也可以表示为 EMS/NMS, 或者称为 EMS管 理后台、 MS管理后台), 其可以在 OLT、 ONU及 CB AT上电后的初始化或认证过程 中识别 OLT和 OLT连接的 ONU, 并识别 ONU连接有 CB AT。 例如: CBAT上电后, 通过 OLT和 ONU间的管理通道将 CBAT的标识传递给 OLT; OLT建立 ONU与 CBAT 之间的对应关系, 并将该对应关系发送给后台管理系统; 后台管理系统接收到该对应 关系后, 确定 ONU连接的 CBAT。 步骤 S304, 后台管理系统通过 OLT和 ONU间的管理通道控制 CBAT。 本实施例中的后台管理系统通过 OLT和 ONU间的管理通道控制 CBAT既包括后 台管理系统通过 OLT和 ONU间的管理通道下发控制信息给 CBAT, 又包括 CBAT通 过管理通道上传控制响应信息给后台管理系统。 其中,后台管理系统通过 OLT和 ONU间的管理通道下发控制信息给 CBAT包括: 后台管理系统按照发送给 ONU消息的格式向 CBAT下发控制消息, 其中, 控制消息 携带有 CBAT的标识; OLT收到控制消息后,解析控制消息确定控制消息是控制 CBAT 的消息,根据 CBAT与 ONU的对应关系将控制消息发送给 ONU; ONU解析控制消息 后确定控制消息是控制 CBAT的消息, 根据 CBAT支持的协议对控制消息进行转换, 将转换后的控制消息发送给 CBAT。
CBAT通过管理通道上传控制响应信息给后台管理系统包括: CBAT根据控制消 息完成控制操作后, 向后台管理系统发送控制响应消息; ONU收到控制响应消息后, 将控制响应消息封装为 ONU的控制响应消息格式后发送给 OLT; OLT对控制响应消 息进行解析后, 将控制响应消息转发给后台管理系统。 其中, OLT和 ONU间的管理通道可以为以下之一: 对于 GPON (Gigabit-Capable PON,千兆无源光网络)系统,为 OMCI (ONU Management and Control Interface, ONU 管理和控制接口)协议通道, 或者, 对于 EPON (Ethernet PON, 以太无源光网络)系 统, 可以为扩展的 OAM (Operations, Administration and Maintenance, 运行、 管理禾口 维护) 协议通道。 下面以 EMS/NMS作为上述后台管理系统, 对 CBAT进行的控制具体为配置管理 为例说明上述方法, 该方法包括:
1 ) EMS/NMS识别 OLT以及相连的 ONU, 并识别 ONU相连的 CBAT; 其中, CBAT发送标识 CBAT的消息给 ONU, ONU通过 OLT和 ONU之间的管理通道传递 相关信息给 OLT, OLT建立了 ONU与 CBAT之间的对应关系, OLT把 ONU和 CBAT 之间的对应关系信息发送给 EMS/NMS, EMS/NMS通过这些对应关系信息识别 ONU 相连的 CBAT。
2) EMS/NMS使用 OLT和 ONU之间建立内部管理通道 (OMCI/扩展 OAM) 传 递管理 CBAT的管理消息; 这里, EMS/NMS管理 CBAT的消息是封装在发送给 ONU 的消息中, OLT根据消息的管理对象, 对消息进行相应的封装。 如果 OLT有本地管理 的接口,如 CLKCommand Line Interface,指令线路接口),则 OLT可以把发送给 CBAT 的消息分装到 OLT和 ONU的内部管理通道; ONU接收到管理 CBAT的消息后,解析 出消息并发给 CBAT, 具体地, ONU可以通过 ONU和 CBAT之间的管理或业务通道 传递管理消息给 CBAT。
3 ) CBAT接收到管理消息后, 进行相关操作处理后, 向 ONU返回相应的管理消 息, ONU接收到 CBAT发送给 EMS/NMS的管理消息后,封装成 OLT和 ONU之间的 内部管理通道上传递的管理消息, 通过 ONU和 OLT 之间的管理通道传递该消息给 EMS/NMS。 在设备形态上, CBAT和 ONU可以为一个集成的设备,也可以为两个独立的设备。 本实施例中, ONU与 CBAT之间的消息通过 ONU和 CBAT之间的管理或业务通道传 递。 CBAT为用户侧的汇集交换设备。 本实施例的后台管理系统通过 OLT和 ONU间的管理通道控制 CBAT, 可以实现 依靠后台管理系统控制 OLT、 ONU和 CBAT, 而不需要为 CBAT设置多个后台管理系 统, 解决了后台管理系统负担较大的问题, 达到使用统一的管理后台控制所有设备的 目的。 实施例 2 本实施例中, OLT通过 EMS管理后台直接进行配置管理, ONU通过 OLT和 ONU 之间的内置管理通道进行配置管理,对 EPON系统来说,该内置管理通道为扩展 OAM, 对 GPON系统来说, 该内置管理系统为 OMCI。 本实施例以对 CBAT进行配置管理为例进行说明, 针对 CBAT的配置管理可以通 过 OLT和 ONU共同完成, 通过 EMS管理后台下发相应的配置管理命令时, OLT根 据配置管理命令对应的管理对象对相关消息进行相应的处理, 在 OLT和 ONU之间通
过内置管理通道的消息类型指明该配置消息是针对 ONU或者是针对 CBAT进行配置。 当 ONU收到该配置消息时, 进行处理, 如果识别出该配置消息为针对 CBAT, ONU 进行处理, 并转换为 CBAT能够识别的消息格式, 对 CBAT进行配置。 下面以 EPON+DOCSIS EOC为例, 如图 4所示, 采用 ONU和 CMTS集成为一个 设备的情况进行说明, 这里该集成设备命名为 CMC (Coaxial media converter) 设备。 EMS管理后台对网元设备 (其中, 包括 OLT、 ONU和 CMTS) 进行配置管理的方法 包括以下步骤: 步骤 S401: EPON+DOCSIS EOC系统中的 CMC设备(包含 ONU和 CMTS设别) 以及 OLT设备上电, 并完成 CMC的初始化和认证过程, 比如 CMC中 ONU的认证过 程等。 步骤 S402: 通过 EMS管理后台对 OLT进行配置管理, 方式可以为 CLI命令行方 式, 也可以为 S MP ( Simple Network Management Protocol, 简单网络管理协议) 接 口方式。 步骤 S403 : 通过 EMS管理后台对 CMC进行配置管理, 方式可以为 CLI命令行 方式,也可以为 S MP接口方式。由于 OLT可以通过上联接口与 EMS管理后台相连, 因此针对 CMC设备的配置管理过程中, OLT可以识别 EMS管理后台当前下发的配置 管理命令的具体对象, 即是针对 CMC设备中的 ONU进行配置管理, 还是针对 CMC 设备中的 CMTS进行配置管理。 根据识别的结果, 形成对应的配置管理消息对 CMC 进行具体配置。 步骤 S404: OLT收到 EMS管理后台下发的配置管理命令后, 会根据识别的该命 令针对的具体的配置对象, 生成具体的扩展 OAM消息, 通过 OLT和 CMC之间的管 理通道, 下发到 CMC上。 如果来自 EMS管理后台的命令是针对 ONU进行配置, 则 可以在扩展 OAM消息的 TIN消息格式中相应字段标明该消息是针对 ONU, 如表 1 所示;反之,则通过扩展 OAM消息的 TIN消息中相应字段标明该消息是针对 CMTS, 如表 2所示。 步骤 S405: CMC接收到来自 OLT的扩展 OAM消息后, 通过扩展 OAM消息中 的特定字段,识别出该消息的配置管理对象为 O J还是 CMTS,如果消息为针对 ONU, 则 ONU直接处理, 使配置管理生效。 如果针对 CMTS, 则 CMC则会把相关消息转化 为 CMTS可以识别的消息格式, 使该命令在 CMTS上最终生效。 表 1:

本实施例的方法, 对 GPON+DOCSIS EOC, 或者其他 PON+DOCSIS EOC同样有 效, 不同的只是不同的 PON系统中 OLT和 ONU之间的管理通道不同。 实施例 3 下面以 EPON+DOCSIS EOC为例, 如图 5所示, 采用 ONU和 CMTS相互独立的 情况进行说明, EMS管理后台对网元设备 (其中, 包括 OLT、 ONU禾 P CMTS) 进行 配置管理的方法包括以下步骤: 步骤 S501 : ONU上电, 完成初始化过程, 该初始化过程包含 MPCP (Multi-Point Control Protocol, 多点控制协议) 识别过程, OAM, eOAM识别过程。 步骤 S502: EMS管理后台通过 S MP管理接口或者命令行对 OLT直接进行配置 和管理。 步骤 S503 : EMS管理后台通过 S MP管理接口或者命令行, 发送针对 ONU的配 置管理消息。
步骤 S504:与 EMS管理后台直接相连的 OLT接收到步骤 S503中针对 ONU的配 置管理消息后,通过 OLT和 ONU之间的扩展 OAM管理通道,对 ONU进行配置管理。 步骤 S505: CMTS上电, 完成 CMTS的初始化过程。 步骤 S506: CMTS和 ONU之间建立通信, 并通过一定的机制维护二者之间的连 接状态。 一旦通信通道成功建立, 则 CMTS将自身的状态和标识信息通知 ONU。 步骤 S507: ONU接收到 CMTS的相关状态信息和标识信息后, 将 CMTS的相关 信息通过 ONU和 OLT之间的扩展 OAM管理通道发送给 OLT, 在 OLT上建立 ONU 与 CMTS的关联关系。 步骤 S508: OLT将已经建立的 ONU和 CMTS的关联信息发送给后台的 EMS管 理后台, 在 EMS服务器上可以查看到 OLT连接的 ONU以及与该 ONU连接的 CMTS 的状态和其他相关信息。 步骤 S509: EMS管理后台将针对 CMTS的配置管理消息通过 S MP管理接口或 者命令行发送给 OLT。 步骤 S510: OLT对接收到的针对 CMTS的配置管理消息进行处理, 进行封装, 如采用上述实施例 2中的表 2中所示的 TIN相应字段来标识针对 CMTS的配置管理。 封装后的扩展 OAM消息通过 OLT和 O J之间的管理通道发送给 O ;。 步骤 S511: ONU对接收到的配置管理消息进行处理, 根据消息中的 TIN相应字 段中的值, 来识别该配置管理消息是针对其连接的 CMTS设备。 进而进行消息格式转 换,转换为 CMTS可以识别的消息格式,通过 O J和 CMTS之间的通道发送给 CMTS。 至此完成针对 CMTS的整个配置管理流程。 本实施例中由于 CMTS和 ONU为两个独立的设备,因此需要维护 ONU和 CMTS 之间的消息通道, 该通道可以为单独的管理通道, 也可以共用业务通道。 本实施例中的方法同样适用于 O J设备下连其他设备时, 比如交换机等, 针对 ONU的其他类型的下游设备的配置管理。 以上实施例 2和实施例 3分别对集成和独立的 CMTS和 ONU进行了举例, 并以
EMS 管理后台对各网元进行配置管理为例进行了说明, EMS 管理后台通过 OLT 和 ONU间的管理通道对 CMTS进行配置管理, 实现了使用同一的后台管理系统配置管
理 OLT、 ONU和 CBAT, 而不需要为 CMTS设置多个后台管理系统, 解决了后台管理 系统负担较大的问题, 达到使用统一的管理后台控制所有设备的目的。 实施例 4 本实施例提供了一种控制 CBAT的系统, 参见图 6, 该系统包括无源光网络 60与 同轴宽带网 70的混合组网, 其中, 无源光网络 60包括 OLT 62和 ONU 64, 同轴宽带 网 70包括 CBAT 72, CBAT 72与 ONU 64相连; 该系统还包括后台管理系统 80, 其 中, 后台管理系统 80包括: 网元识别模块 82,与 OLT 62相连,设置为识别 OLT 62和 OLT 62连接的 ONU 64, 并识别 ONU 64连接的 CBAT 72; 控制模块 84, 与网元识别模块 82相连, 设置为通过 OLT 62和 ONU 64间的管理 通道控制网元识别模块 82识别的 CBAT 72。 本实施例中的无源光网络可以是 PON、 EPON或 GPON等, 同轴宽带网可以是 EOC, 也可以是 DOCSIS EOC。 本实施例的混合组网可以是 PON+EOC混合组网, 或 者 EPON+DOCSIS EOC混合组网等。 后台管理系统 80可以是 EMS或 NMS, 其可以在 OLT、 ONU及 CBAT上电后的 初始化或认证过程中识别 OLT和 OLT连接的 ONU, 并识别 ONU连接有 CBAT。 基 于此, 上述 CBAT 72包括: 标识上传模块, 设置为 CBAT 72上电后, 通过 OLT 62和 ONU 64间的管理通道将 CBAT 72的标识传递给 OLT 62; OLT 62包括: 关系建立与 发送模块,设置为收到 CBAT 72的标识后,建立 ONU 64与 CBAT 72之间的对应关系, 并将对应关系发送给后台管理系统; 网元识别模块 82包括: 识别单元, 设置为接收到 OLT 62发送的对应关系后, 确定 ONU 64连接的 CBAT 72。 本实施例中的后台管理系统 80通过 OLT 62和 ONU 64间的管理通道控制 CBAT 72既包括后台管理系统 80通过 OLT 62和 ONU 64间的管理通道下发控制信息给 CBAT
72, 又包括 CBAT 72通过管理通道上传控制响应信息给后台管理系统。 其中, 后台管理系统 80按照发送给 ONU 64消息的格式向 CBAT 72下发控制消 息, 其中, 控制消息携带有 CBAT 72的标识; OLT 62收到控制消息后, 解析控制消 息确定控制消息是控制 CBAT 72的消息, 根据 CBAT与 ONU 64的对应关系将控制消 息发送给 ONU 64; ONU 64解析控制消息后确定控制消息是控制 CBAT 72的消息, 根据 CBAT 72支持的协议对控制消息进行转换,将转换后的控制消息发送给 CBAT 72。
CBAT 72根据控制消息完成控制操作后, 向后台管理系统 80发送控制响应消息; ONU 64收到控制响应消息后,将控制响应消息封装为 ONU 64的控制响应消息格式后 发送给 OLT 62; OLT 62对控制响应消息进行解析后, 将控制响应消息转发给后台管 理系统 80。 本实施例中的 ONU 64与 CB AT 72通过 ONU 64和 CB AT 72之间的管理或业务通 道传递消息。 ONU 64和 CBAT 72可以为一个集成的设备; 或者, ONU 64和 CBAT 72 也可以为两个分别独立的设备。 本实施例提供的系统可以应用在上述实施例 1-3 中, 各个设备所完成的操作与上 述实施例中的操作相同, 这里不再赘述。 本实施例中的 CBAT为用户侧的汇聚交换设备, 不限于上述实施例中的 CMTS, 还可以是交换机等下游设备。 本实施例的后台管理系统通过 OLT和 ONU间的管理通道控制 CBAT, 可以实现 依靠后台管理系统控制 OLT、 ONU和 CBAT, 而不需要为 CBAT设置多个后台管理系 统, 解决了后台管理系统负担较大的问题, 达到使用统一的管理后台控制各个网元的 效果。 从以上的描述中可以看出, 以上实施例中的后台管理系统采用 EMS/NMS管理系 统同时管理 PON系统以及 DOCSIS EOC系统中的设备, 即可以直接管理 OLT、 ONU 和 CBAT, 具体通过 OLT做代理, 统一管理 ONU和 CMTS, 降低了后台管理系统的 负担。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而, 可以 将它们存储在存储装置中由计算装置来执行, 并且在某些情况下, 可以以不同于此处 的顺序执行所示出或描述的步骤, 或者将它们分别制作成各个集成电路模块, 或者将 它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限制于任 何特定的硬件和软件结合。 以上所述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。
