IPTV ( Internet Protocol TV: 因特网协议电视 )是随着宽带网络、 流传 输、编解码等技术的发展而出现的互联网新业务，是被业界称为 "Triple play (三元播放）" 的业务体现。 IPTV业务对网络传输的质量要求很高， 如何保 证 IPTV的 QoS ( quality of service: 业务质量）， 为用户提供实时、 流畅、 高 清晰的音视效果引起运营商的广泛关注。
根据一些运营商 IPTV故障统计结果， 终端问题、 线路问题和设备侧问 题占问题单总数的 80 % , 是 IPTV用户故障申告的主要来源。
如何精确判定用户业务故障的位置， 提高故障定位解决效率， 是运营商 急需解决的问题。
目前主要有一些手持的仪表工具， 在用户端通过对 IPTV播放的过程进 行抓包分析来完成一些 IPTV测试项目的测试。 但是， 这种故障诊断需要上 门测试， 不能长期监测， 定位偶然故障的原因比较困难。 并且， 不能立刻检 查用户报障时的故障， 可能会错过故障定位的有利时机。
另外，也可以在 CO( Central Office:中心局）的 DSLAM( digital subscriber line access multiplexer: 数字用户线接入多路复用器） 下行口部署 CPE仿真 测试设备。 但是， 这种 CPE ( Customer Premises Equipment: 用户驻地设备 ) 仿真测试设备只能感知 CO以上的网络故障， 无法定位某一用户的故障， 不 能感知用户线路或用户终端的故障，无法定位由于用户的业务行为影响造成 的故障。 发明内容

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例是本发明一部分实施例， 而不是 全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创 造性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
图 1是本发明实施例的业务质量监测设备的示意性框图。 如图 1所示， 根据本发明实施例的用于数字用户线路（DSL: digital subscriber line ) 宽带 网络的业务质量监测设备 10包括： DSL局端收发模块 101 , 与 DSL宽带网 络的 DSL用户终端连接； DSL远端收发模块 102, 与 DSL宽带网络的 DSL 业务提供方连接； 业务监测模块 103,连接在 DSL局端收发模块 101和 DSL 远端收发模块 102之间， 用于在 DSL局端收发模块 101和 DSL远端收发模 块 102之间传递 DSL业务数据报文， 并进行 DSL业务数据报文的业务质量 监测。
根据本发明实施例的业务质量监测设备， 可以实现及时定位故障、 全面 定位故障和长期监测。 即， 运维人员可以在用户申告故障的第一时间进行故 障定位监测， 有利于把握故障定位的时机， 及时解决可以立即解决的问题。 并且， 通过分析 DSL用户终端与 DSL业务提供方之间的交互报文， 不仅可 以分析 DSL宽带网络的网络端的故障， 也可以感知 DSL宽带网络的用户端 引起的故障， 更有利于故障的及时排除。 此外， 还可以在不影响用户的使用 业务的前提下， 监测用户的业务质量， 从而能够对偶然性故障进行长期的监 测、 定位。
图 2是以 IPTV宽带网络为例， 本发明实施例的业务质量监测设备具体 应用环境的示意图。如图 2所示，本发明实施例的业务质量监测设备与 TAM ( Test Access Matrix: 测试接入矩阵 )连接， 用于监测在 CPE和 DSLAM之 间的特定用户的业务数据报文， 以分析业务质量故障的原因、 确定故障点。 如图 2所示， 用户的电视通过机顶盒（STB: set-top box )与 CPE连接， 并 且用户的 PC可以直接与 CPE连接。
下面， 将以如图 2所示的 IPTV宽带网络为例， 对根据本发明实施例的 用于 DSL宽带网络的业务质量监测设备进行具体描述。 在以下的描述中， DSL局端收发模块具体为 ATU-C ( ADSL Transceiver Unit, Central office end: ADSL 局端收发单元）， 且 DSL 远端收发模块具体为 ATU-R ( ADSL Transceiver Unit, Remote terminal end: ADSL远端^:发单元 ), 并^1 DSL业 务数据报文筒称为业务数据报文。 本领域技术人员可以理解， 虽然在本发明 的实施例中以 IPTV宽带网络为例进行了描述， 但本发明实施例所述的业务 质量监测设备不仅限于应用于 IPTV宽带网络， 其也可以应用于其它类型的 DSL宽带网络。
图 3是根据本发明实施例的业务质量监测设备及其应用环境的示意图。 在所述 IPTV宽带网络中，在业务提供方和用户终端之间传递业务数据报文， 其中， CPE对应于宽带网络的用户终端， 而 DSLAM对应于宽带网络的业务 提供方。
如图 3 所示， 根据本发明实施例的业务质量监测设备 20 包括 ATU-C ( ADSL Transceiver Unit, Central office end: ADSL局端收发单元） 201、 ATU-R ( ADSL Transceiver Unit, Remote terminal end: ADSL远端收发单元 ) 202和业务监测模块 203。其中， ATU-C 201用于与用户数字用户线路（ DSL ) 连接， 其接收来自 CPE的业务数据报文并发送到业务检测模块 203, 以及接 收来自业务检测模块 203的业务数据报文并发送到 CPE。例如，该 ATU-C 201 可以是用户家里的 DSL调制解调器， 端接 DSL线并传送以太报文。 在本发 明的实施例中， 该 ATU-C 201经由外测总线与 CPE连接。 ATU-R 202用于 与用户数字用户线路（DSL )连接， 其接收来自 DSLAM的业务数据报文并 发送到业务检测模块 203, 以及接收来自业务检测模块 203的业务数据报文 并发送到 DSLAM。 该 ATU-R 202可以是中心局的 DSL调制解调器， 端接 DSL线并传送以太 文。 在本发明的实施例中， 该 ATU-R 202经由内测总 线与 DSLAM连接。并且，业务监测模块 203连接在 ATU-C 201和 ATU-R 202 之间， 用于在 ATU-C 201和 ATU-R 202之间传递用户的业务数据报文， 并 对传递的业务数据报文进行复制，从而对复制的业务数据报文进行业务质量 监测。 这里， 业务监测模块 203对业务数据报文进行的业务质量监测是指通 过对业务数据报文的质量指标的计算和监控来分析业务质量故障的原因并 确定故障点。
在本发明的实施例中， 因为业务监测模块 203 连接在 ATU-C 201 和 ATU-R 202之间， 用于桥接 ATU-C 201和 ATU-R 202之间的业务数据报文， 所以实现了 CPE和 DSLAM之间的数据传递。
进一步地， 本发明实施例的业务监测设备可以包括线路切换开关， 以切 换业务监测设备的不同工作状态， 下面将结合图 4-8进行具体描述。
图 4是本发明实施例的具有线路切换开关的业务质量监测设备的示意性 框图。 在图 7的业务质量监测设备 30中， ATC-C 301、 ATU-R 302和业务监 测模块 303分别与如图 3所示的业务质量监测设备 200中的 ATU-C 201、 ATU-R 202和业务监测模块 203相同， 在此不再赘述。
与如图 3所示的业务质量监测设备 20不同， 如图 4所示的业务质量监 测设备 30进一步包括第一开关 S1和第二开关 S2。 在如图 4所示的业务质 量监测设备 30中， 第一开关 S1和第二开关 S2用作线路切换开关， 以灵活 地控制监测方式，
下面， 将参考图 5-8描述本发明实施例的具有线路切换开关的业务质量 监测设备的不同工作状态。
图 5是示出了本发明实施例的具有线路切换开关的业务质量监测设备的 第一工作状态的说明图。 如图 5所示， 在第一工作状态中， 用户业务正常运 行， 此时用户线路直接连通， 从而实现在 CPE和 DSLAM之间的业务数据 报文的传递。 此时本发明实施例的业务质量监测设备处于空闲状态， 其 ATU-C和 ATU-R通过业务监测模块连接。 并且， 第一开关将 ATU-C与内部 测试线连接， 第二开关将 ATU-R和内部测试线连接。 这里， 在业务质量监 测设备处于空闲状态时， 由于 ATU-C和 ATU-R通过业务监测模块连接， 并 经由第一开关、 内部测试线和第二开关构成电路回路， 可以预先进行业务质 量监测设备的配置准备。 这里， 本领域技术人员可以理解， 配置准备的内容 包括 PVC配置 /调制模式配置 /速率模板配置等。
图 6是示出了本发明实施例的具有线路切换开关的业务质量监测设备的 第二工作状态的说明图。 如图 6所示， 在第二工作状态中， 本发明实施例的 业务质量监测设备与 TAM连接， 从而 CPE与本发明实施例的业务质量监测 设备的 ATU-C 连接， 且 DSLAM 与本发明实施例的业务质量监测设备的 ATU-R连接。 CPE和 DSLAM之间传递的业务数据 文通过本发明实施例的 业务质量监测设备的业务监测模块， 从而进行业务数据报文的业务质量监 测。
图 7是示出了本发明实施例的具有线路切换开关的业务质量监测设备的 第三工作状态的说明图。 如图 7所示， 在第三工作状态中， 进行 CPE仿真 测试。 此时， 本发明实施例的业务质量监测设备的 ATU-R与 DSLAM连接， 本发明实施例的业务质量监测设备可以模拟 CPE设备的相关业务操作， 从 而实现对 DSLAM用户端口、 7 载网的传输质量测试和故障识别。
图 8是示出了本发明实施例的具有线路切换开关的业务质量监测设备的 第四工作状态的说明图。 如图 11 所示， 在第四工作状态中， 进行 DSLAM 仿真测试。 此时， 本发明实施例的业务质量监测设备的 ATU-C与用户家中 的 CPE连接， 本发明实施例的业务质量监测设备可以模拟 DSLAM等业务 提供方的相关业务操作， 从而实现对用户线路侧的业务质量测试和故障识 别。
进一步地，本发明实施例的具有线路切换开关的业务质量监测设备可以 包括 LPF ( Low pass filter: 低通滤波器）， 该 LPF与内部测试线并联地连接 在内测总线和外测总线之间， 用于保证在业务质量监测过程中不影响用户的 电话业务。 当 TAM设备中已经存在低通元件时， 可以省略该 LPF。
在图 5到图 8的四种工作状态中， 除了图 6所示的第二工作状态之外， CPE均没有与 DSLAM直接连通， 因此没有在 CPE和 DSLAM之间传递的 业务数据报文。此时，为了进行业务监测设备的配置准备或者 CPE或 DSLAM 的仿真测试， 本发明实施例的业务监测设备可以预先复制并存储一份儿在 CPE和 DSLAM之间传递的业务数据报文，以根据该业务数据报文进行业务 监测设备的配置准备或者 CPE或 DSLAM的仿真测试。
可选地， 在本发明的实施例中， 以上如图 1到图 8所示的业务质量监测 设备可以进一步包括业务数据转发接口， 用于与外接的业务监测设备连接， 从而向外接的业务监测设备转发在 CPE和 DSLAM之间传递的用户的业务 数据报文。 在本发明的实施例中， 业务监测模块对在 ATU-C和 ATU-R之间 传递的业务数据报文进行复制，从而将复制的业务数据报文经由业务数据转 发接口转发到外接的业务监测设备， 以在特殊应用场景下满足对该业务数据 报文进行深度分析和业务回放的需要。
通过上述业务数据转发接口， 本发明实施例的业务监测模块除了对在 CPE和 DSLAM之间传递的用户的业务数据报文进行质量指标计算和监控以 分析业务质量故障的原因并确定故障点之外，还可以实现业务数据报文的复 制和转发， 从而实现了业务的被动监控和主动测试的结合。
下面， 将结合图 9到图 11对本发明实施例的业务质量监测设备的业务 监测模块的具体配置进行进一步的说明。 这里， 本领域技术人员可以理解， 图 9到图 11所示的业务检测模块的配置可以应用于以上如图 1到图 8中所 示的任意一个业务检测模块。
图 9是本发明实施例的业务监测模块的第一配置示例的框图。如图 9所 示， 使用数据复制转发芯片来实现 ATU-C和 ATU-R之间业务数据报文的传 递， 并进一步实现业务数据报文到外接网口的转发。 例如， 该数据复制转发 芯片可以是 LANS witch芯片。 具体地说， ATU-C和 ATU-R之间传递的业务 数据报文在经过 LANS witch芯片时， 由 LANS witch芯片对该业务数据报文 进行复制， 并将复制的业务数据报文传送到用于进行业务质量监测的 CPU, 此外， 该 LANS witch 芯片还可以将复制的业务数据报文转发到外接网口， 如上述的业务数据转发接口。 其中， 该复制的业务数据报文经过 PHY (物理 层）单元和 MAC (媒体访问控制层）单元传送到 CPU中的业务监测单元， 以进行业务数据报文的业务质量监测。 这里， PHY单元和 MAC单元分别是 网口的物理层控制单元和链路层媒体访问控制单元。 PHY单元连接网线。 MAC单元在发送数据的时候， 可以事先判断是否可以发送数据， 如果可以 发送将向数据添加一些控制信息， 最终将数据以及控制信息以规定的格式发 送到物理层；在接收数据的时候，首先判断输入的信息并是否发生传输错误， 如果没有错误， 则去掉控制信息发送至上一层。 图 10是本发明实施例的业务监测模块的第二配置示例的框图。 如图 10 所示， 业务监测模块中进行业务质量监测的 CPU进一步设置有用于数据复 制转发的数据复制转发单元， 该数据复制转发单元分别包括与 ATU-C对应 的第一 PHY单元和第一 MAC单元，与 ATU-R对应的第二 PHY单元和第二 MAC单元， 并且可以进一步包括与外接网口对应的第三 PHY单元和第三 MAC单元。 该数据复制转发单元分别通过与 ATU-C连接的第一 PHY单元 和第一 MAC单元以及与 ATU-R连接的第二 PHY单元和第二 MAC单元来 实现 ATU-C和 ATU-R之间业务数据报文的传递。 并且， 该数据复制转发单 元复制在 ATU-C和 ATU-R之间传递的业务数据报文， 并通过第三 PHY单 元和第三 MAC单元转发到外接网口。 此外， 该数据复制转发单元还可以将 在 ATU-C和 ATU-R之间传递的业务数据报文复制到业务监测单元， 以进行 业务数据报文的业务质量监测。
图 11是本发明实施例的业务监测模块的第三配置示例的框图。 如图 11 所示， 使用数据转发复制逻辑芯片来实现 ATU-C和 ATU-R之间业务数据报 文的传递。 并且， 该数据转发复制逻辑芯片将在 ATU-C和 ATU-R之间传递 的业务数据报文存储在 MEM (内存） 中。 在 MEM中存储的业务数据报文 可以复制到业务监测单元以进行业务数据报文的业务质量监测， 并且进一步 可以发送到数据复制单元， 以由数据复制单元将复制的业务数据报文经由 PHY单元和 MAC单元转发到外接网口。
这里， 本领域技术人员可以理解， 图 9到图 11仅示出了本发明实施例 的业务监测模块的三个配置示例， 本发明实施例的业务监测模块的具体实现 还可以有另外的实现方法， 本发明实施例并不意在对此进行任何限制。
另外， 如上所述， 当应用于 IPTV宽带网络时， 将本发明实施例的业务 监测设备的 DSL局端收发模块和 DSL远端收发模块分别具体为 ATU-C和 ATU-R。但是，当应用于 IPTV宽带网络以外的其它类型的 DSL宽带网络时， 需要将 ATU-C 201和 ATU-R 202替换为适于其它 DSL宽带网络类型的 DSL 局端收发单元和 DSL远端收发单元， 以使得本发明实施例的业务监测设备 可以接入该类型的 DSL宽带网络中。 在接入 DSL宽带网络中之后， 业务监 测设备所进行的 DSL业务数据报文的业务质量监测与上述实施例中的类似， 在此便不再赘述。
下面，将参考图 12描述本发明实施例的业务质量监测设备的工作方法。 图 12是示出了本发明实施例的业务质量监测设备的工作方法的示意性流程 图。 其中， 所述业务质量监测设备可以具有如图 1所示的示例性配置。 如图 12所述， 本发明实施例的用于 DSL宽带网络的业务质量监测设备的工作方 法 40包括： 401 , 与 DSL宽带网络的 DSL用户终端连接； 402, 与 DSL宽 带网络的 DSL业务提供方连接； 以及 403, 在 DSL用户设备和 DSL业务提 供方之间传递 DSL业务数据报文， 并进行 DSL业务数据报文的业务质量监 测。
在上述方法中，与 DSL宽带网络的 DSL用户终端连接可以包括：从 DSL 宽带网络的 DSL业务提供方获取 DSL宽带网络的用户线路的配置信息； 根 据所获取到的配置信息配置业务质量检测设备的 DSL局端收发单元； 控制 DSL宽带网络的测试接入矩阵将用户线路接入到 DSL局端收发模块； 以及 完成 DSL局端收发模块与 DSL用户设备的宽带网络连接。
在上述方法中， 与 DSL宽带网络的 DSL业务提供方连接可以包括： 从 DSL宽带网络的 DSL业务提供方获取 DSL宽带网络的用户线路的配置信息； 根据所获取到的配置信息配置 DSL远端收发单元； 控制 DSL宽带网络的测 试接入矩阵将用户线路接入到 DSL远端收发模块； 以及完成 DSL远端收发 模块与 DSL业务提供方的宽带网络连接。

此外， 可选地， 在上述方法中， 业务质量监测设备包括第一开关和第二 开关， 并控制第一开关和第二开关以在业务质量监测设备的业务测试线和 DSL宽带网络的测试接入矩阵之间切换，以使得业务质量监测设备处于空闲 状态、 监测状态、 DSL用户终端仿真测试状态和 DSL业务提供方仿真测试 状态。 其具体描述与之前关于图 5-8所述的相同， 在此便不再赘述。
此外， 可选地， 在上述方法中， 可以将复制的始发的 DSL业务数据报 文和回应的 DSL业务数据报文转发到业务质量监测设备的业务报文转发接 口， 以向经由所述业务报文转发接口向外接的业务监测设备转发在 DSL业 务提供方和 DSL用户终端之间传递的 DSL业务数据报文。
图 13是示出了本发明实施例的业务质量监测设备的另一工作方法的示 意性流程图。 在图 13所示的示例性的业务质量监测设备的工作方法 50中， 将参考图 4所示的具有线路切换开关的业务质量监测设备进行描述。如图 13 所示， 在 501 , 本发明实施例的业务质量监测设备获取从 CPE到 DSLAM的 用户线路上的配置信息， 例如， 业务质量监测设备可以从 DSLAM获取监测 用户 ATU-C和 ATU-R的相关信息， 包括配置信息和速率模板等。 在 502, 根据获取到用户线路上的配置信息， 例如 ATU-C信息配置本发明实施例的 业务质量监测设备的 ATU-C, 并根据用户线路上的配置信息， 例如 ATU-R 信息配置本发明实施例的业务质量监测设备的 ATU-R。 在 503, 控制 TAM 抓线， 将用户线路接入到本发明实施例的业务质量监测设备的 ATU-C 和 ATU-R。 在 504, 本发明实施例的业务质量监测设备的 ATU-C和 CPE完成 xDSL的连接， 同时本发明实施例的业务质量监测设备的 ATU-R和 DSLAM 完成 xDSL的连接。 在 505, 由 CPE发送的用户的业务数据报文经本发明实 施例的业务质量监测设备的 ATU-C处理后进入到业务监测模块， 业务监测 模块将业务数据报文由 ATU-R发送到 DSLAM,同时复制该业务数据报文以 转发到业务报文映像接口。 在 506, DSLAM回应的业务数据报文经本发明 实施例的业务质量监测设备的 ATU-R接收后进入到业务监测模块， 业务监 测模块将业务数据报文由 ATU-C发送到用户 CPE, 对于业务数据报文进行 业务质量监测， 同时复制该业务数据报文以转发到业务报文映像接口。 在 507 , 本发明实施例的业务质量监测设备的业务监测模块对复制的业务数据 报文进行业务质量监测， 进行故障判定。
图 14是示出了本发明实施例的用于 DSL宽带网络的系统的框图。 如图 14所示， 该系统 60包括业务监测设备 601 , DSL用户终端 602和 DSL业务 提供方 603。 该业务监测设备 601可以是之前描述的任意业务监测设备。
在本发明实施例的业务质量监测设备及其工作方法和系统中，通过在利 用成熟应用的 DSLAM、 CPE套片的基础上增加业务监测模块， 可以在已有 的线路测试设备实现业务的主动、 被动全面监测。
并且， 通过在 DSLAM端集中部署本发明实施例的业务质量监测设备， 可以监控业务质量劣化和进行业务回放， 为业务质量故障定位提供了切实的 数据。
此外， 利用业务监测模块还可以实现主动给用户推送质量故障信息， 提 高运维效率。 并且， 该功能的实现不依赖于其他任何系统， 本发明实施例的 业务质量监测设备本身即可以实现该业务测试。
另外， 通过在局端部署本发明实施例的业务质量监测设备， 可以通过分 析用户端发送的报文来感知业务的质量及故障。
此外， 在本发明实施例的业务质量监测设备及其工作方法和系统中， 可 以在用户投诉时就发起测试， 监测用户的业务情况， 提高了故障定位的准确 性。 并且， 可以在不影响用户使用的情况下， 实现长期监控， 有利于定位偶 然故障。
