Description

光网络单元 ONU数据处理方法、 装置及系统 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数据处理方法、 装 置及系统。 背景技术 无源光网络 (Passive Optical Network, 简称为 PON) 技术目前已经是光接入网领 域首选技术, 其在接入速率、 带宽效率和分光比、 全业务承载能力以及安全性方面都 具有明显优势。 PON技术还分为以太无源光网络 (Ethernet Passive Optical Network, 简称为 EPON) 和千兆无源光网络 (Gigabit Passive Optical Network, 简称为 GPON), EPON技术由 IEEE802.3 EFM (Ethernet for the First Mile) 工作组进行标准化; GPON 技术是由 ITU-T(国际电信联盟远程通信标准化组;)提出并标准化。 当前通过网管对光网络单元 (Optical Network Unit, 简称为 ONU) 进行远程管理 有下面两种主要方式,一种是网管通过简单网络管理协议( Simple Network Management Protocol,简称为 S MP)下发数据到光线路终端(Optical Line Terminal,简称为 OLT), 对于 EPON, OLT 接收管理数据后, 将这些数据封装到运行、 管理和维护中心 (Operations, Administration and Maintenance, 简称为 OAM)帧中, 发送给 ONU终端, 对于 GPON, 根据 ITU-T相关标准定义的受管实体 (Managed Entity, 简称为 ME)来设 置管理对象, 并通过光网络单元管理控制界面 (ONT Management and Control Interface, 简称为 OMCI)帧传输 ONU管理数据。 另外一种方式是建立网管与 0LT设 备的管理通道以及 OLT与 ONU之间的管理通道, 最终建立起网管与 ONU之间的管 理通道, 然后网管通过 S MP协议直接管理 ONU, OLT只提供通道, 不做数据上的 处理。 方式一的问题是,随着工程上对于 P0N终端应用的各类新增需求不断变化且与日 倶增, 0LT的版本发布周期已无法跟上需求变化频率, 且新增需求要首先完善标准, 而标准的变更与完善需要漫长过程。 另外 OLT版本升级影响很大, 很难经常性升级, 因此方式一对于新需求的响应能力很差。 方式二不需要升级 0LT版本, 只需要升级网管及 0NU即可满足新需求, 但也存 在一些问题, 首先方式二只适用于多用户居住单元 (Multiple Dwelling Unit, 简称为 MDU)这类非用户家庭的 0NU, 简单家庭单元( Single Family Unit, 简称为 SFU)这 类用户家庭的 ONU只能采用方式一。 另外只能对在线 0NU进行管理, 因为只有在线 ONU才能建立起管理通道, 这样就增加了 ONU管理的局限性。 因此, 在相关技术中对光网络单元的管理存在一定因素的局限性: 类型因素、 是 否在线的状态因素, 以及版本升级因素。 发明内容 本发明提供了一种光网络单元 ONU数据处理方法、 装置及系统, 以至少解决相 关技术中对光网络单元的管理存在一定因素的局限性: 类型因素、 是否在线的状态因 素, 以及版本升级因素的问题。 根据本发明的一个方面, 提供了一种光网络单元 ONU数据处理方法, 包括: 网 络管理系统将用于处理所述 ONU的数据生成 ONU数据包;所述网络管理系统将生成 的所述 ONU数据包发送给光线路终端 OLT, 其中, 所述 OLT将接收的所述 ONU数 据包发送给所述 ONU。 其中, 所述 ONU数据包包括以下至少之一: 用于配置操作的配置命令数据包、 用于查询操作的查询命令数据包。 根据本发明的另一方面, 提供了一种光网络单元 ONU数据处理方法, 包括: 光 线路终端 OLT接收网络管理系统下发的用于处理所述 ONU的 ONU数据包;所述 OLT 将接收到的所述 ONU数据包发送给所述 ONU。 其中, 在所述 OLT将接收到的所述 ONU数据包发送给所述 ONU之前, 还包括: 所述 OLT检测所述 ONU是否在线, 在确定所述 ONU在线的情况下, 所述 OLT将接 收到的所述 ONU数据包发送给所述 ONU。 其中, 所述 OLT将接收到的所述 ONU数据包发送给所述 ONU包括: 所述 OLT 判断接收到的所述 ONU数据包是用于配置操作的配置命令数据包还是用于查询操作 的查询命令数据包; 在所述 ONU数据包为所述配置命令数据包的情况下, 所述 OLT 将接收的所述配置命令数据包进行存储, 将所述配置命令数据包发送给所述 ONU; 和 /或, 在所述 ONU数据包为所述查询命令数据包, 所述 OLT将所述查询命令数据包发 送给所述 ONU。 根据本发明的再一方面, 提供了一种光网络单元 ONU数据处理方法, 包括: 光 网络单元 ONU接收光线路终端发送的 ONU数据包, 其中, 所述 ONU数据包为网络 管理系统下发的用于处理所述 ONU的数据包; 所述 ONU依据接收到的所述 ONU数 据包进行数据处理。 其中, 在所述 ONU依据接收到的所述 ONU数据包进行数据处理之前, 还包括: 所述 ONU依据与所述网络管理系统的预先约定对接收到的所述 ONU数据包进行解 析, 在确定对所述 ONU数据包解析成功的情况下, 所述 ONU依据解析结果进行数据 处理。 其中, 所述 ONU依据接收到的所述 ONU数据包进行数据处理包括: 所述 ONU 判断接收的所述 ONU数据包是用于配置操作的配置命令数据包还是用于查询操作的 查询命令数据包; 在所述 ONU数据包为所述配置命令数据包的情况下, 所述 ONU依 据所述配置命令数据包执行配置操作处理; 和 /或, 在所述 ONU数据包为所述查询命 令数据包的情况下, 所述 ONU依据所述查询命令数据包执行查询操作处理。 其中, 在所述 ONU依据接收到的所述 ONU数据包进行数据处理之后, 还包括: 所述 ONU将执行配置操作处理后的配置结果信息和 /或执行查询操作处理后的查询结 果信息反馈给所述网络管理系统, 其中, 所述 OLT将从所述 ONU接收到的所述配置 结果信息和 /或所述查询结果信息透传给所述网络管理系统。 根据本发明的再一方面, 提供了一种光网络单元 ONU数据处理装置, 位于网络 管理系统中,包括:生成模块,设置为将用于处理所述 ONU的数据生成 ONU数据包; 第一发送模块, 设置为将生成的所述 ONU数据包发送给光线路终端 OLT, 其中, 所 述 OLT将接收的所述 ONU数据包发送给所述 ONU。 根据本发明的还一方面, 提供了 种光网络单元 ONU数据处理装置, 位于光线 路终端 OLT中, 包括: 第一接收模块, 设置为接收网络管理系统下发的用于处理所述 ONU的 ONU数据包; 第二发送模块, 设置为将接收到的所述 ONU数据包发送给所 述 ONU。 其中, 该装置还包括: 检测模块, 设置为检测所述 ONU是否在线, 在确定所述 ONU在线的情况下, 所述 OLT将接收到的所述 ONU数据包发送给所述 ONU。 其中, 所述第二发送模块包括: 第一判断单元, 设置为判断接收到的所述 ONU 数据包是用于配置操作的配置命令数据包还是用于查询操作的查询命令数据包; 第一 发送单元, 设置为在所述 ONU数据包为所述配置命令数据包的情况下, 所述 OLT将 接收的所述配置命令数据包进行存储, 将所述配置命令数据包发送给所述 ONU; 和 / 或, 第二发送单元, 设置为在所述 ONU数据包为所述查询命令数据包, 所述 OLT将 所述查询命令数据包发送给所述 ONU。 根据本发明的又一方面, 提供了一种光网络单元 ONU数据处理装置, 位于光网 络单元 ONU中, 包括: 第二接收模块, 设置为接收光线路终端发送的 ONU数据包, 其中, 所述 ONU数据包为网络管理系统下发的用于处理所述 ONU的数据包; 处理模 块, 设置为依据接收到的所述 ONU数据包进行数据处理。 其中, 该装置还包括: 解析模块, 设置为依据与所述网络管理系统的预先约定对 接收到的所述 ONU数据包进行解析, 在确定对所述 ONU数据包解析成功的情况下, 所述 ONU依据解析结果进行数据处理。 其中, 所述处理模块包括: 第二判断单元, 设置为判断接收的所述 ONU数据包 是用于配置操作的配置命令数据包还是用于查询操作的查询命令数据包; 第一处理单 元, 设置为在所述 ONU数据包为所述配置命令数据包的情况下, 依据所述配置命令 数据包执行配置操作处理; 和 /或, 第二处理单元, 设置为在所述 ONU数据包为所述 查询命令数据包的情况下, 依据所述查询命令数据包执行查询操作处理。 其中, 该装置还包括: 反馈模块, 设置为将执行配置操作处理后的配置结果信息 和 /或执行查询操作处理后的查询结果信息反馈给所述网络管理系统, 其中, 所述 OLT 将从所述 ONU接收到的所述配置结果信息和 /或所述查询结果信息透传给所述网络管 理系统。 根据本发明的还又一方面, 提供了一种光网络单元 ONU数据处理系统, 包括: 上述位于网络管理系统中的 ONU数据处理装置、 上述任一项所述的位于光线路终端 OLT中的 ONU数据处理装置和上述任一项所述的位于光网络单元 ONU中的 ONU数 据处理装置。 通过本发明, 采用网络管理系统将用于处理所述 ONU的数据生成 ONU数据包; 所述网络管理系统将生成的所述 ONU数据包发送给光线路终端 OLT,其中,所述 OLT 将接收的所述 ONU数据包发送给所述 ONU, 解决了解决相关技术中对光网络单元的 管理存在一定因素的局限性: 类型因素、 是否在线的状态因素, 以及版本升级因素的 问题, 进而达到了不需要为网络管理系统与 ONU之间特意建立相关管理通道, 也不 需要考虑 ONU 的是否在线的状态, 其中涉及的光线路终端也不需要进行时常升级才 能进行数据处理的效果。 附图说明 此处所说明的附图用来提供对本发明的进一步理解, 构成本申请的一部分, 本发 明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的不当限定。 在附图 中: 图 1是根据本发明实施例的光网络单元 ONU数据处理方法一的流程图; 图 2是根据本发明实施例的光网络单元 ONU数据处理方法二的流程图; 图 3是根据本发明实施例的光网络单元 ONU数据处理方法三的流程图; 图 4是根据本发明实施例的光网络单元 ONU数据处理装置一的结构框图; 图 5是根据本发明实施例的光网络单元 ONU数据处理装置二的结构框图; 图 6是根据本发明实施例的光网络单元 ONU数据处理装置二的优选结构框图; 图 7是根据本发明实施例的光网络单元 ONU数据处理装置二中第二发送模块 54 的优选结构框图; 图 8是根据本发明实施例的光网络单元 ONU数据处理装置三的结构框图; 图 9是根据本发明实施例的光网络单元 ONU数据处理装置三的优选结构框图一; 图 10是根据本发明实施例的光网络单元 ONU数据处理装置三中处理模块 84的 优选结构框图; 图 11 是根据本发明实施例的光网络单元 ONU数据处理装置三的优选结构框图

步骤 S104, 网络管理系统将生成的 ONU数据包发送给光线路终端 OLT, 其中, OLT将接收的 ONU数据包发送给 ONU。 通过上述步骤, 对于网络管理系统来说, 将用于处理 ONU的数据生成 ONU数据 包, 基于网络管理系统与光线路终端 OLT之间, 以及 OLT与 ONU之间的基础连接, 将生成的 ONU数据包由网络管理系统发送给 ONU, 相对于相关技术中网络管理系统 对 ONU进行管理时, 需要建立特定的管理通道, 不仅解决了相关技术中对光网络单 元的管理存在一定因素的局限性: 类型因素、 是否在线的状态因素, 以及版本升级因 素的问题, 进而达到了不需要为网络管理系统与 ONU之间特意建立相关管理通道, 也不需要考虑 ONU 的是否在线的状态, 其中涉及的光线路终端也不需要进行时常升 级才能进行数据处理的效果。 在本实施例中还提供了一种光网络单元 ONU数据处理方法, 图 2是根据本发明 实施例的光网络单元 ONU数据处理方法二的流程图, 如图 2所示, 该流程包括如下 步骤: 步骤 S202, 光线路终端 OLT接收网络管理系统下发的用于处理 ONU的 ONU数 据包; 步骤 S204, OLT将接收到的 ONU数据包发送给 ONU。 对于光线路终端 OLT而言,基于网络管理系统与光线路终端 OLT之间,以及 OLT 与 ONU之间的基础连接, 将网络管理系统下发的用于处理 ONU的 ONU数据包发送 给 ONU, 相对于相关技术中网络管理系统对 ONU进行管理时, 需要建立特定的管理 通道, 不仅解决了相关技术中对光网络单元的管理存在一定因素的局限性:类型因素、 是否在线的状态因素, 以及版本升级因素的问题, 进而达到了不需要为网络管理系统 与 ONU之间特意建立相关管理通道, 也不需要考虑 ONU的是否在线的状态, 其中涉 及的光线路终端也不需要进行时常升级才能进行数据处理的效果。 在 OLT将接收到的 ONU数据包发送给 ONU之前,相对于相关技术中需要对 ONU 数据包进行管理通道的控制或是对 OLT的升级, 该 OLT仅需要检测 ONU是否在线, 在确定 ONU在线的情况下, OLT将接收到的 ONU数据包发送给 ONU, 即相对于相 关技术中通过管理通道对 ONU进行管理是需要在 ONU在线时才能实现对 ONU的操 作处理, 而在本实施例中不需要保证 ONU在线, 即在 ONU不在线时网络管理系统也 可以向 OLT传送 ONU的 ONU数据包, 只要之后检测到 ONU时即通过 OLT与 ONU 之间的基础结构就能够实现 ONU数据包的传送,大大提高了网络管理系统对 ONU的 高效管理。 在 OLT将接收的 ONU数据包发送给 ONU时依据数据包的命令的不同, 可以进 行不同的操作, 可以采用以下处理: OLT判断接收到的 ONU数据包是用于配置操作 的配置命令数据包还是用于查询操作的查询命令数据包; 在 ONU数据包为配置命令 数据包的情况下, OLT将接收的配置命令数据包进行存储, 将配置命令数据包发送给 ONU;和 /或,在 ONU数据包为查询命令数据包, OLT将查询命令数据包发送给 ONU。 依据配置命令与查询命令的不同分别进行操作处理。 在本实施例中还提供了一种光网络单元 ONU数据处理方法, 图 3是根据本发明 实施例的光网络单元 ONU数据处理方法三的流程图, 如图 3所示, 该流程包括如下 步骤:
步骤 S302, 光网络单元 ONU接收光线路终端发送的 ONU数据包, 其中, ONU 数据包为网络管理系统下发的用于处理 ONU的数据包; 步骤 S304, ONU依据接收到的 ONU数据包进行数据处理。 对于光网络单元 ONU而言,基于网络管理系统与光线路终端 OLT之间,以及 OLT 与 ONU之间的基础连接, 依据通过光线路终端 OLT透传来自网络管理系统的 ONU 数据包的处理, 相对于相关技术中网络管理系统对 ONU进行管理时, 需要建立特定 的管理通道, 不仅解决了相关技术中对光网络单元的管理存在一定因素的局限性: 类 型因素、 是否在线的状态因素, 以及版本升级因素的问题, 进而达到了不需要为网络 管理系统与 ONU之间特意建立相关管理通道,也不需要考虑 ONU的是否在线的状态, 其中涉及的光线路终端也不需要进行时常升级才能进行数据处理的效果。 在所述 ONU依据接收到的所述 ONU数据包进行数据处理之前, 还包括: 所述 ONU依据与所述网络管理系统的预先约定对接收到的所述 ONU数据包进行解析, 在 确定对所述 ONU数据包解析成功的情况下, 所述 ONU依据解析结果进行数据处理。 相对于相关技术中网络管理系统对 ONU的管理需要建立特定的涉及 OLT的管理通道, 通过上述处理, ONU可以直接依据与网络管理系统的约定对 ONU数据包进行解析, 依据解析的结果进行对应的操作处理, 不仅不需要对 OLT进行频繁升级, 而且能够对 ONU在线或是离线均能进行有效管理。 在 ONU依据接收的 ONU数据包进行数据处理时, 依据接收到的 ONU数据包的 不同处理时可以分别操作: 例如, 在接收到 ONU数据包时, ONU先判断接收的 ONU 数据包是用于配置操作的配置命令数据包还是用于查询操作的查询命令数据包; 在 ONU数据包为配置命令数据包的情况下, 依据配置命令数据包执行配置操作处理; 和 /或, 在 ONU数据包为查询命令数据包的情况下, 依据查询命令数据包执行查询操作 处理。 其中, 在 ONU依据接收到的 ONU数据包进行数据处理之后, ONU还可以将执 行配置操作处理后的配置结果信息和 /或执行查询操作处理后的查询结果信息反馈给 网络管理系统, 其中, OLT将从 ONU接收到的配置结果信息和 /或查询结果信息透传 给网络管理系统。 在本实施例中还提供了一种光网络单元 ONU数据处理装置, 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 4是根据本发明实施例的光网络单元 ONU数据处理装置一的结构框图,如图 4 所示, 该装置位于网络管理系统中, 该装置包括: 生成模块 42和第一发送模块 44, 下面对该装置进行说明。 生成模块 42, 设置为将用于处理 ONU的数据生成 ONU数据包; 第一发送模块

OLT不对数据包做任何解析处理, 直接将其保存在 OLT上。 步骤 S1312, 监控 ONU状态; 步骤 S1314, ONU是否在线?在判断结果为是的情况下, 进入步骤 S1316, 否则 返回步骤 S1312; 即 OLT会检测网管所要操作的 ONU是否在线, 如果在线, 进入步骤 S1316, 在 ONU不在线情况下, 返回步骤 S1312, OLT会继续监控该 ONU在线情况, 直到 OLT 发现 ONU上线。 步骤 S1316, OLT将数据包下发到 ONU; OLT将网管传来的, 且已经保存在 OLT上的数据包原封不动地、不做任何处理的 下发给 ONU。 步骤 S1318, ONU接收数据包, 解析后执行配置操作;

OLT从网管收到的是查询命令, 如果在线, 则进行步骤 S1322, 否则处理结束。 步骤 S1322, OLT将数据包下发到 ONU; OLT将网管传来的含有 ONU查询信息的数据包原封不动地、 不做任何处理的下 发给 ONU。 步骤 S1324, ONU接收数据包, 解析后执行查询操作, 并把查询结果返回 OLT;
ONU接收到 OLT发来的含有查询信息的数据包后, 会按照与网管约定的协议解 析数据包, 然后执行查询操作, 查询结果返回给 OLT。 步骤 S1326, OLT把从 ONU上接收到的查询结果返回给网管; OLT将从 ONU上接收到的含有查询结果的数据包原封不动地发给网管, 网管会 按照与 ONU约定的协议解析查询结果数据包, 然后将结果显示在网管界面上。 步骤 S 1326, 处理结束。 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。 工业实用性 如上所述, 解决了相关技术中对光网络单元的管理存在一定因素的局限性: 类型 因素、 是否在线的状态因素, 以及版本升级因素的问题, 进而达到了不需要为网络管 理系统与 ONU之间特意建立相关管理通道, 也不需要考虑 ONU的是否在线的状态, 其中涉及的光线路终端也不需要进行时常升级就能进行数据处理的效果。
