Description

宽带接入终端参数配置方法
技术领域
本发明涉及通信领域的接入技术, 特别涉及采用数字用户环路技术 的宽带接入终端参数配置方法。
背景技术
数字用户环路(xDSL )是由美国贝尔通信研究所为推动点播图像 ( Video on Demand, 筒称 "VOD" )业务而开发的利用双绞线传输高速数 据的技术,是各种类型数字用户线( Digital Subscriber Line, 简称 "DSL" ) 的总称, 其使用现有的普通电话线路传输数据、 话音以及视频信号, 传 输速率高达每秒几兆比特。
所有的 DSL技术均基于现有的普通铜芯电话线路, 采用信号调制提 高传输速率。 根据信号传输速率和距离的不同, 以及上行信道和下行信 道对称性的不同, xDSL 可分为非对称数字用户线 (Asymmetric Digital Subscriber Line, 简称 "ADSL" ). 速率自适应数字用户线( Rata Adaptive Digital Subscriber Line, 简称 "RADSL" )、 甚高速数字用户线( Very High Speed Digital Subscriber Line, 简称 "VDSL" )、 单线对高速率数字用户线 ( Single-line DSL, 简称 "SDSL" )、 综合业务数字网 (ISDN, Integrated Services Digital Network )数字用户线( ISDN Digital Subscriber Line , 简 称 "IDSL" )以及高速数字用户线( HIGH SPEED DIGITAL SUBSCRIBER LINE, 简称 "HDSL" )等。
其中, ADSL宽带技术兼容窄带和宽带业务, 利用特有的调制解调硬 件, 通过现有的电话线连接用户端和业务接入端。 采用 ADSL技术, 在 普通电话线上传输数据的速率可以达到普通拨号调制解调器 ( Modulator/Demodulator, 筒称 "MODEM" ) 的 140倍。 ADSL将带宽 分为三部分, 一部分用于传输话音, 一部分传输上行数据, 另一部分传 输下行数据。 上行信道的带宽远小于下行信道的带宽, 其最高能以 640kbit/S的速率传输数据, 因此也称为 "不对称技术"。 通过采用 "不对 称" 传输, 可以保证用户侧的串音比对称传输系统低, 从而提高了传输 速率, 延长了传输距离。
ADSL的主要特点在于: 高速传输、 上网和打电话互不干扰、安装快 捷方便。 随着 Internet的迅速发展, ADSL作为一种高速接入 Internet的 技术, 具有一定的生命力, 使现有 Internet上提供多媒体服务成为可能。
截止到 2005年 1季度末, 全球包含 ADSL在内的 DSL用户线数达 到 1500万线, 预计到 2010年底, DSL宽带用户线数将达到 5000万线, 宽带用户的规模增长直接导致宽带运维压力增大。 如何解决终端的即插 即用和远程在线管理问题是宽带运维的关键工作之一。
具体的说, 对于上述 ADSL系统而言, 即插即用是指 ADSL终端能 够自动获取业务所需的配置, 换句话说, ADSL终端上电后, 从服务端设 备获取相关业务配置, 利用这个配置, 开展后续的业务应用, 或者业务 开展过程中, 服务端设备能够远程配置终端的参数, 更新业务数据。 此 处的服务端设备包括数字用户线接入复用器 (Digital Subscriber Line Access Multiplexer, 筒称 "DSLAM" )、 宽带远程接入服务器(Broadband Remote Access Server, 简称 " BRAS" ) 以及网管等。
下面介绍目前常用的两种 ADSL终端获取业务参数的方法。
第一种方法: 在网管生成 ADSL终端配置参数, 通过 DSLAM将该 ADSL终端配置参数透传给 ADSL终端。 具体的说, 当 ADSL终端上电 重启时, 请求 DSLAM下载终端配置参数, DSLAM响应该请求, 向网 管服务器转发, 请求其下发该 ADSL终端的配置参数, 网管服务器响应 请求, 将终端配置参数发送给 DSLAM, 然后再由 DSLAM发送给 ADSL 终端。
上述方法的缺点在于, 为了随时响应来自 DSLAM 的请求, 网管服 务器必须时刻在线, 否则就会出现终端不能获取预先配置参数的现象, 导致无法正常工作, 由此引入了一个不稳定系统。 另外, 网络配置终端 参数层次较多, 操作复杂。
笫二种方法: 在 DSLAM直接生成终端配置参数, 由 DSLAM本地 维护口配置的终端参数。
这种方法的缺点在于, 由于是在 DSLAM上直接配置, 不同厂家的 DSLAM的命令格式不一致,维护界面也不一致,由此导致维护难度较大, 对维护工程要求也比较高, 不好集中管理。 也就是说, 维护难度大, 实 施比较困难。
发明内容
有鉴于此, 本发明的主要目的在于提供一种宽带接入终端参数配置 方法, 使得既有比较好的稳定性, 又操作简单, 维护方便, 容易实施。

第二个表是终端配置模板信息, 其中包含终端配置模板索引和永久 虚拟线路的对应关系,
第三个表是永久虚拟线路所对应的虚信道连接的信息,
第四个表是虚信道连接所对应的异步传输模式适配层模板信息。 此外, 还包含以下步骤:
所述终端从所述数字用户线接入复用器下载配置参数后保存下载的 内容。
此外, 所述步骤 A中, 还包括: 网管侧在下发配置参数之前从网管 侧的配置文件中获取配置参数。
本发明提供的一种宽带接入终端参数配置方法, 包括:
A 网管侧将需要配置到所述终端的配置参数下发到该终端所属的接 入设备;
B 所述接入设备将来自所述网管侧的配置参数保存在本地;
C所述终端和所述接入设备进行交互, 从该接入设备下载配置参数 并更新配置。
通过比较可以发现, 本发明的技术方案与现有技术的主要区别在于, 配置参数由网管侧生成,并下发到 DSLAM, DSLAM保存该配置参数后, 通过 DSLAM与终端的交互完成配置参数的下载。
此外, 终端可以在启动时或运行中请求下载, 下载可以由终端执行 也可以由 DSLAM执行。
在网管侧, 需要配置的参数可以通过对四个表的查询获取。
这种技术方案上的区别, 带来了较为明显的有益效果, 即因为网管 侧只参与配置参数的生成(一次性的 ), 之后全由 DSLAM完成终端配置 参数的下载, 网管侧即使发生故障也不会对终端配置参数的下载造成任 何影响, 所以相对于第一种现有技术方案, 本发明提高了稳定性, 减少 网絡配置终端参数层次, 操作了筒化。 另一方面, 因为配置参数是在网 管侧生成的, 所以相对于第二种现有技术方案, 本发明可以使用统一维 护界面和统一的命令格式, 减小了维护难度, 实施起来更为容易。
此外, 配置参数存放在四个表中可以大大减少数据的冗余程度, 维 护起来更为方便。

请参阅图 1 ,本发明的参数配制方法涉及的 ADSL系统包括网管和连 接网管的 DSLAM, 终端连接至 DSLAM。
图 4 示出根据本发明的第一实施例的终端参数配置方法的流程示意 图。 如图所示, 在本实施例中, 包含以下步骤:
步骤 410: 网管根据业务需要, 将相应的参数配置到 DSLAM。
在本步驟中, 通过网管(参见图 1 )中维护的四个表完成参数配置工 作, 它们是:
端口表( Port Table ), 该表用于表示端口索引和终端配置模板索引的 对应关系;
终端永久虚拟线路(Permanent Virtual Circuit, 简称 "PVC" )配置模 板表 ( confi PVC Profile Table;), 其中包含终端配置模板索引和永久虚拟 线路的对应关系;
虚信道连接( Virtual Channel Connection,简称 "VCC" )连接表( atmVcc
Table ), 表中是永久虚拟线路所对应的虚信道连接的信息; 以及,
ATM适配层 (ATM Adaptation Layer, 简称 "AAL" ) 配置模板表 ( atmAALl(2/3/4/5)Profile Talble ) , 其中, ATM 指异步传输模式 "Asynchronous Transfer Mode" , 表中是虚信道连接所对应的异步传输模 式适配层模板信息。
需要指出的是, 上述四个表之间存在一定的关系, 参见图 2和图 3 , 对于端口表, 其中的每一个终端可应用一个配置特定 PVC模板, 每一个 PVC模板可以分别引用不同 VCC连接, 对于每一个 VCC连接, 可使用 不同的 AAL参数。
如图 2和图 3所示, 终端参数的配置过程为: 首先才艮据端口索引, 在端口表中找到对应的终端配置模板索引。 此后, 根据该终端配置模板 索引,在终端 PVC配置模板表中找到该端口所对应的各 PVC的索引。接 着, 根据每一个 PVC索引在 VCC连接表中找到该 PVC所相应的 VCC 连接。 最后, 根据 VCC连接表中的 AAL索引, 从 AAL配置模板表中找 到该 VCC相应的 AAL配置模板,该 AAL配置模板中包含有公共部分会 聚子层(Common Part Convergence Sublayer, 简称 "CPCS" )转发参数、 CPCS 后向参数以及 AAL模式等信息。 由此网管从上述四个表中找到 ADSL终端所对应的配置参数。
由此可见, 在本步骤中, 在参数配置过程中利用了四个表, 并采用 模板形式的终端参数配置管理。 换句话说, 即把相同的配置内容组合成 一个模板, 这些模板可以被其他配置引用。 此外, 本步骤采用两级模板 的配置管理模式: 终端 PVC配置模板和 AAL配置模板。 其中, 参数配 置表的两级模板方式, 实现一个终端 (端口) 能够采用任意配置模板、 而终端配置模板可使用合适 ATM流量模板参数。在这种情况下,本步骤 实际上采用了比较高效的配置数据的保存方式, 可以最大限度地减少数 据冗余。
步驟 420: DSLAM接受网管配置操作,将终端配置参数转换成需要, 即与 ADSL终端信号相匹配的参数或格式。 具体的说, 来自网管的配置 参数可以是一种与终端类型无关的统一格式, 下发到 DSLAM后, 由 DSLAM根据终端的实际类型作相应的转换。这种转换可以是将一个参数 分解成多个参数, 也可以是将多个参数合并成一个参数, 还可以是格式 上的转换, 如将字符串类型改成终端所要求的整数类型。 这种在 DSLAM 的转换可以减少网管侧的复杂度。 在本发明的其他实施例中, 也可以将 终端配置参数直接保存在 DSLAM设备中。
步骤 43Q: ADSL终端通过和 DSLAM的交互,下载和更新配置参数。 具体的说, 在本实施例中, 在 ADSL终端上电重启过程中, ADSL终端 向 DSLAM发送请求, 并在得到确认后, 主动下载 /读取保存在 DSLAM 中的终端配置参数。 需要指出的是, 在本发明中, 也可以使用其他方式 实现 ADSL终端下载和更新配置参数, 这将在后面的实施例中——描述。
不难理解, 在本实施例中, 由于网管将 ADSL终端配置参数配置到 DSLAM, 因此不必如同前面的第一种现有技术方案那样必须确保网管服 务器时刻在线; 另一方面, 由于和第二种现有技术方案相比, 不是在 DSLAM上直接配置终端参数,因此不会有由于不同长假命令格式不一致 或维护界面不一致而导致维护难度大、 实施困难的问题。
图 5 示出根据本发明的第二实施例的终端参数配置方法的流程示意 图。 如图所示, 在本实施例中, 包含以下步驟:
步骤 510: 网管根据业务需要, 将相应的参数配置到 DSLAM。 在本 步骤中, 终端参数的配置过程和第一实施例的情况一样, 在此不再赘述。 在本步骤中, 在参数配置过程中同样利用了四个表, 并采用模板形式的 终端参数配置管理。 换句话说, 即把相同的配置内容组合成一个模板, 这些模板可以被其他配置引用。 此外, 本步骤采用两级模板的配置管理 模式: 终端 PVC配置模板和 AAL配置模板。 其中, 参数配置表的两级 模板方式, 实现一个终端 (端口) 能够采用任意配置模板、 而终端配置 模板可使用合适 ATM流量模板参数。如上所述,本步骤实际上采用了比 较高效的配置数据的保存方式, 可以最大限度地减少数据冗余。 其中, 四个表之间的关系以及具体配置过程可直接参见图 2和图 3 ,以及第一实 施例中的相关描述。
步骤 520: DSLAM接受网管配置操作,将终端配置参数转换成需要, 即与 ADSL终端信号相匹配的参数或格式。
步驟 530: ADSL终端通过和 DSLAM的交互,下载和更新配置参数。 在本实施例中, 不同于第一实施例的, 通过以下子步骤实现: ADSL终端 上电重启过程中, ADSL终端向 DSLAM发送请求指令, 然后由 DSLAM 主动下载 /设置终端配置参数。
图 6 示出根据本发明的第三实施例的终端参数配置方法的流程示意 图。 如图所示, 在本实施例中, 包含以下步驟:
步骤 610: 网管根据业务需要, 将相应的参数配置到 DSLAM。 在本 步驟中, 终端参数的配置过程和第一实施例的情况一样, 在此不再赘述。 其中, 四个表之间的关系以及具体配置过程可直接参见图 2和图 3, 以及 第一实施例中的相关描述。
步骤 620: DSLAM接受网管配置操作,将终端配置参数转换成需要, 即与 ADSL终端信号相匹配的参数或格式。
步驟 630: ADSL终端通过和 DSLAM的交互,下载和更新配置参数。 在本实施例中,不同于第一和第二实施例的,通过以下子步骤实现: ADSL 终端运行过程中通过本地口发指令, 即, 用户按终端上的按钮, 请求 DSLAM,并且,在得到确认后, ADSL终端主动下载 /读取保存在 DSLAM 中的终端配置参数。
图 7示出根据本发明的第四实施例的终端参数配置方法的流程示意 图。 如图所示, 在本实施例中, 包含以下步骤:
步骤 710: 网管根据业务需要, 将相应的参数配置到 DSLAM。 在本 步骤中, 终端参数的配置过程和第一实施例的情况一样, 在此不再赘述。 其中, 四个表之间的关系以及具体配置过程可直接参见图 2和图 3, 以及 第一实施例中的相关描述。

步骤 730: ADSL终端通过和 DSLAM的交互,下载和更新配置参数。 在本实施例中, 不同于第一、 第二和第三实施例的, 通过以下子步骤实 现: ADSL终端运行过程中请求 DSLAM,并由 DSLAM主动下载 /设置终 端配置。
图 8 示出根据本发明的第五实施例的终端参数配置方法的流程示意 图。 如图所示, 在本实施例中, 包含以下步骤:
步骤 810: 网管根据业务需要, 将相应的参数配置到 DSLAM。 在本 步骤中, 终端参数的配置过程和第一实施例的情况一样, 在此不再赘述。 其中, 四个表之间的关系以及具体配置过程可直接参见图 2和图 3 , 以及 第一实施例中的相关描述。
步骤 820: DSLAM接受网管配置操作,将终端配置参数转换成需要, 即与 ADSL终端信号相匹配的参数或格式。
步骤 830: ADSL终端通过和 DSLAM的交互,下载和更新配置参数。 如上所述, 该步骤可以通过第一到第四实施例中任意一种用相应的子步 骤实现。
步骤 840: 在 ADSL终端保存下载或更新配置参数。 在本发明中, 这 个步驟是可选, 可由终端根据业务需要配置决定是否需要保存这个终端 配置。
图 9 示出根据本发明的第六实施例的终端参数配置方法的流程示意 图。 如图所示, 在本实施例中, 包含以下步骤:
步驟 910: 网管根据业务需要, 将相应的参数配置到 DSLAM。 在本 步骤中, 终端参数的配置过程和第一实施例的情况一样, 在此不再赘述。 其中, 四个表之间的关系以及具体配置过程可直接参见图 2和图 3 , 以及 第一实施例中的相关描述。
步骤 920: 与前面的实施例不同的是, 将终端配置参数直接保存在 DSLAM设备中。
步骤 930: ADSL终端通过和 DSLAM的交互,下载和更新配置参数。 如上所述, 该步骤可以通过第一到第四实施例中任意一种用相应的子步 骤实现。
步驟 940: 在 ADSL终端保存下载或更新配置参数。
除了上述这些实施例之外, 在本发明的另一个实施例中, 通过另一 种方式实现了 ADSL终端参数的配置, 该方式中, 不是从四个表中查询 获取配置参数, 而是在一个位于网管侧的配置文件中获取。 该配置文件 中包含了所有类型终端的配置参数。
通过以上对本发明的实施例的具体描述可见, 在本发明中, 由于网 管将 ADSL终端配置参数配置到 DSLAM,因此避免了每一次终端上电重 启时都需要通过 DSLAM请求下载终端配置参数的情况, 由此, 不再要 求网管服务器始终保持在线状态, 提高了系统的稳定性, 并且, 操作也 更加简便。 此外, 有效解决了当在 DSLAM直接生成终端配置参数而由 于 DSLAM的不同的命令格式或维护界面导致维护和实施工作中的问题, 減小了维护和实施的难度。
虽然通过参照本发明的某些优选实施例, 已经对本发明进行了图示 和描述, 但本领域的普通技术人员应该明白, 可以在形式上和细节上对 其作各种改变, 而不偏离本发明的精神和范围。
