Description

数字用户线端口信息收集方法及系统 技术领域 本发明涉及通信领域, 具体而言, 涉及一种数字用户线端口信息收集方 法及系统。 背景技术 宽带业务已经成为电信运营商的主要投资方向, 业务收入不断增长。 数 字用户线 (Digital Subscriber Line, 简称为 DSL ) 因依托现有线路、 开通快 速、 投资回报率高、 利用现网潜效等特点, 成为宽带主流技术。 中国是全球 DSL应用规模最大的市场, DSL业务也已成为中国电信增长最快的业务及收 入增长的主要来源。 但宽带业务随着网络规模和用户数量扩增, 宽带质量问 题日益凸显。 网速慢、 异常掉线是目前用户反应比较强烈的热点问题, 也是 用户对宽带质量不满意、 引发用户投诉的主要因素。 数字用户线是一种不断发展的宽带接入技术, 该技术是釆用先进的数字 编码技术和调制解调 (Modem )技术在常规的用户铜质双绞线上传送宽带信 号。 目前, 已经比较成熟并且投入使用的数字用户线方案有非对称数字用户 线 ( Asymmetric Digital Subscriber Line, 简称为 ADSL ), 第二代非对称数字 用户线 ( Asymmetric Digital Subscriber Line 2/2Plus, 简称为 ADSL2/2+ ) 和 甚高速数字用户线 ( Very high speed Digital Subscriber Line , 简称为 VDSL ), 第二代甚高速数字用户线 ( Very high speed Digital Subscriber Line 2, 简称为 VDSL2 )等多种数字用户线。 一般而言, 上述所有 DSL都统称为 xDSL。 上 述方案都是通过一对调制解调器来实现, 其中, 一个调制解调器设置在电信 局, 另一个调制解调器设置在用户侧。 数字用户线接入系统, 主要包括: 数字用户线接入复用器 (DSL Access Multiplexer, 简称为 DSLAM)、 客户端设备 ( Customer Premises Equipment, 简称为 CPE )和网络管理系统( Network Management System , 简称为 NMS ) 等。 以下进一步分析数字用户线接入系统的故障: 1、 DSL链路异常掉线: DSL异常掉线指客户端设备与数字用户线接入 复用器的连接非正常中断,这种故障主要由线路质量引起,线路末梢缺陷(交 接箱、 分线盒、 引入线和用户室内线) 是诱发掉线的主要因素。 用户线路过 长、 MODEM质量、 局端 DSLAM的配置以及软件版本不合理容易引发异常 掉线。
2、 网速慢: 网速慢是用户对宽带传输速率的一种比较差的体验, 除了 骨千网和业务站点的原因外, 在接入层, 用户感受网速†曼主要由于以下两个 原因: ( 1 ) DSLAM 端口速率不达标, 其中, DSLAM 端口速率不达标是指 用户 MODEM和 DSLAM的同步速率氐于用户申请的业务速率,主要由线路 问题和分离器问题所引起;( 2 )DSLAM和宽带远程服务器( Broadband Remote Server, 简称为 BRS )组网不合理,例如, DSLAM级联过多、 IP上行 DSLAM 分布在同一 VLAN的用户端口过多、 接入网层次不清 (即 BAS和 DSLAM 垮城域网互连以及 BAS上连带宽不足) 等。 其中, 与 DSL链路层相关的是链路稳定性和链路性能。 DSL链路异常 掉线大多由于链路的不稳定所导致, 而 DSLAM 端口速率不达标大多由于 DSL物理线路的链路性能差造成。 DSL承载的业务问题,主要涉及到 DSLAM 上层网络及其相关设备软硬件的问题。 针对 DSL链路层的稳定性和性能的线路管理系统,主要包括数字用户线 端口的信息釆集、 诊断与分析、 策略等功能。 该线路管理系统的组网具体可 以参见图 1。 图 1为线路管理系统的组网示意图。 如图 1所示, 该网络主要包括: 数字用户线接入复用器 101 , 主要用于完成数字用户线接入的复用和解 复用, 包括调制解调、 数字用户线管理等。 客户端设备 102 , 主要为调制解调器, 用于帮助用户从以太网数据转为 DSL数据。 线路管理系统 103 , 主要是进行所辖的数字用户线接入复用器下的数字 用户线端口的相关信息釆集、 诊断与分析、 策略实施。 网络管理系统 104 , 主要是进行所辖的数字用户线接入复用器的远程网 络管理。 业务网络 105 , 主要是数字用户线接入复用器的出口所在的网络。 通常 经过交换机、 路由器等设备后, 再经过宽带接入服务器 ( Broadband Remote Access Server, 简称为 BRAS )认证后进入公用网络。 针对线路管理系统,目前基本上釆用主动进行端口扫描方式来收集信息。 通常情况下, 一个线路管理系统所管理的用户为十万至数百万。 釆用这种方 式存在的主要问题如下: 扫描效率低。 早期釆用扫描全部用户 (每个用户对应一个物理数字用户 线端口), 非常耗时。 即使通过策略优化, 仅对部分用户扫描, 以 30 %为例, 用户数量通常也在三万至百万。 如果以 10个线程 5秒无障碍情况下并发扫 描并处理一个用户来计算, 扫描五十万个用户大 4既需要 69.4小时。 扫描的有效性差。 扫描时, 用户可能未激活或者已激活多次。 由于存在 扫描周期和扫描时间等问题, 在扫描到某个用户的时候, 可能用户端口未激 活或者已经激活过多次。 一种情况是用户端口在扫描时未激活; 另一种情况 是在两次扫描期间已经激活过多次。 虽然可以通过数字用户线接入复用器的 端口信息增加相关字段来记录上一次建链的相关参数信息, 但是如果在两次 扫描期间多次激活和去激活后, 将只保留最后一次建链的相关参数信息。 由 于数字用户线端口的不同用户的工作背景、 生活方式差异很大, 因此上线时 间和上线后的在线时间上可能差别很大。 这将导致釆集信息时一些用户的信 息无法釆集到, 并艮难弥补。 发明内容 针对相关技术中线路管理系统釆用主动进行端口扫描方式来收集信息 时, 扫描效率低且扫描的有效性差的问题, 本发明提供了一种数字用户线端 口信息收集系统及方法, 以解决上述问题至少之一。 根据本发明的一个方面, 提供了一种数字用户线端口信息收集方法。 根据本发明的数字用户线端口信息收集方法包括: 数字用户线接入复用 器获取与当前用户线端口对应的预设策略信息;

( 1 ) 网络管理系统从线路管理系统中获取预设策略信息;
( 2 ) 网络管理系统将预设策略下发至数字用户线接入复用器。 在具体实施过程中, 数字用户线接入复用器获取与当前用户端口对应的 预设策略信息之后, 更新到釆集策略数据库, 以便在端口事件触发时查询并 釆取相应的釆集策略。 具体可以参见图 6。 图 6是根据本发明实施例的数字用户线接入复用器 (下称网元) 记录监 控对象的参数信息的流程图。 如图 6所示, 该网元记录监控对象的参数信息 包括以下处理 (步骤 S602-步骤 S608 ): 步骤 S602: 网元的某个端口发生了建链、 掉链、 速率变化等监控事件的 触发事件。 步骤 S604: 网元查询该端口是否属于端口监控列表, 确定是否需要进行 监控及其后续操作。 如果否, 则到步骤 610退出事件触发。 如果是, 则到步 骤 S606。 步骤 S606: 网元查询该端口当前事件是否属于端口事件监控列表。 如果 否, 则流程结束退出事件触发。 如果是, 则执行步骤 S608。 步骤 S608: 才艮据监控对象要求的参数记录要求进行记录。 通常情况下, 不同监控对象要求记录不同的参数信息。 例如, 对于"端口不达标,,的情况, 通常记录以下信息, 但不限于以下信 息:
( 1 ) 用户号码;
( 2 ) 用户网元 IP、 机架、 机框、 槽位、 端口; ( 3 ) 事件时间、 记录触发类型;
( 4 ) 达标目标值参数, 例如: 业务的目标上下行速率;
( 5 ) 实际值参数, 例如: 上下行实际速率;
( 6 ) 端口的管理状态、 操作状态;
( 7 ) 诊断用的参数: 可达速率、 线路衰减、 噪声容限、 发射功率; ( 8 ) 其他辅助参数: 例如, 终端的套片厂家和固件版本。 例如, 对于"端口掉链"的情况, 通常记录以下信息, 但包括不仅限于以 下信息:

( 6 ) 存在错误并且不能纠错的带封装的块数 ( UncorrectBlks ); ( 7 ) 端口初始化以来累计的成功训练次数、 失败训练次数; 可选地, 上述信息还可以包括: 动态参数信息, 即记录从建链过程信息 及其对应的掉链过程的信息。 通常情况下一定记录建链过程, 后续的正常运 行过程如果没有异常情况(实际信噪比余度发生较多变化等)可以不用记录, 在发生掉链时关闭记录动作。 优选地, 从发起建链到最后掉链的过程可以釆 用文件方式存储, 也可以釆用数据库存储。 线路管理系统收集网元的端口信息数据时可以釆用两种方式: 第一种: 线路管理系统主动轮询网元。 在具体实施过程中, 线路管理系统通过轮询 (直接或者通过网络管理系 统) 来收集网元相关端口的参数信息。 轮询时, 针对网元的实际情况, 可以 釆用 FTP等协议来进行数据获取。 第二种: 网元主动要求上传记录。 优选地, 当网元存储的参数信息的信息量达到预定阈值时, 网元请求上 传参数信息。 在具体实施过程中, 由于网元存储信息容量的限制, 可以在网元存储空 间或者记录数达标一定数量时主动向线路管理系统发起上传请求, 由线路管 理系统取走端口参数信息, 并清除记录。 考虑到网元的时间不一定准确或者说是相对时间, 因此每次网元在上传 端口参数信息时必须增加批次字段。 具体地, 该批次字段可以用一个格式的 时间字符串表示。 以下结合图 7和图 8对上述两种方式的实现方法进行描述。 图 7是才艮据本发明实施例的釆集模块主动轮询网元收集网元的端口参数 信息的流程图。如图 7所示,该流程主要包括以下处理(步骤 S702-步骤 S710 ): 步 4聚 S702: 线路管理系统本地策略触发收集流程, 流程启动。 步骤 S704: 线路管理系统的轮询单元整理待收集的网元列表。 其中, 在 轮询网元时,可以釆用单线程或者多线程方式或者多计算机分摊等各种方式。 步骤 S706: 如果待收集的网元列表为空, 则结束一次轮询网元釆集端口 参数信息的流程, 否则, 则执行步骤 S708。 步骤 S708: 轮询釆集模块取得一个网元信息, 并从待收集的网元列表中 删除该网元条目。 步骤 S710: 取得一个目标网元的端口参数信息记录, 可以釆用 FTP等 协议来进行数据获取。 图 8是才艮据本发明实施例的网元主动要求上传记录情况下的流程图。 如 图 8所示, 该流程主要包括以下处理 (步骤 S802-步骤 S820 ): 步骤 S802: 网元经过执行才艮据事件触发要求记录端口参数信息; 步骤 S804: 网元判断目前此类监控对象的记录是否达到记录容量最大 值。 如果是, 则结束本次流程, 否则, 到步 4聚 S 806。 步骤 S806: 网元判断目前此类监控对象的记录是否达到记录容量告警门 限。 如果是, 则到步 4聚 S808, 否则, 到步 4聚 S820。 步骤 S808: 此类监控对象的记录达到记录容量告警门限, 网元向线路管 理系统发起立即釆集的请求, 希望尽快取走端口历史参数信息, 以便腾出容 量来记录新的信息。 步骤 S810: 网元等待线路管理模块接的反馈, 如果线路管理模块接受釆 集要求, 则到步骤 S818; 否则到步骤 S812。 步骤 S812: 如果在规定时间内没有收到同意的请求, 则失败计数加 1。 没有收到线路管理模块的可能情况包括: 网络问题导致请求丢失或不完整被 艮务侧丢弃、 线路管理模块艮务忙无法响应等。 步骤 S814: 判断计数是否超过失败计数最大值, 如果是,则结束请求, 到步 4聚 S816; 否则到步 4聚 S808, 继续请求上传。 步骤 S816: 在线路管理模块艮务无法同意上传请求时, 放弃上传请求。 步骤 S818: 在艮务侧接受上传请求后, 网元开始将历史端口参数信息记 录上传。 步骤 S820: 根据监控对象和事件记录当前端口的参数信息。 优选地, 在执行步骤 S506之后, 还可以包括以下处理:
( 1 ) 线路管理系统根据收集的参数信息进行用户线端口故障分类;
( 2 ) 线路管理系统根据故障分类结果确定造成故障的原因。 上述处理过程具体可以参见图 9。 图 9是才艮据本发明实施例的用户端口故障分类分析流程图。如图 9所示, 该流程主要包括以下处理 (步骤 S902-步骤 S914 ): 步骤 S902: 生成本次用户端口分析表, 选定要分析的记录的范围通常情 况下按月份进行统计分析, 也可以按 1个或多个批次或者某个时间范围内, 也可以进一步限制网元的地理区域等信息。 步骤 S904: 从用户信息表同步用户相关信息。 用户必须是指定分析范围 内有效的。 步骤 S906: 居分析规则对本次用户端口的历史参数表进行预处理。 剔 除用户端口历史参数记录中记录不完整或者上行或者下行速率为 0或空等各 种异常的记录, 并进一步剔除历史记录全部达标的记录和对应的用户。 新增 以下字段: 上行结果、 下行结果、 上行可达很低、 下行可达很低、 上行可达 很高、 下行可达很高、 日期有效等字段, 还可以扩展设备厂商等字段。 并根 据分析达标端口信息判定细节计算得到每个新增字段的值, 供后续用户端口 信息统计使用。 步骤 S908: 根据本次用户端口的历史参数表的分析字段的数据, 对用户 端口分析表进行预处理。 新增以下字段: 扫描次数、 上行达标次数、 下行达 标次数、 上行速率平均、 下行速率平均、 上行速率变动次数、 下行速率变动 次数、 上行可达平均、 下行可达平均、 上行可达变动次数、 下行可达变动次 数、 上行可达艮氏次数、 下行可达艮氏次数、 上行可达艮高次数、 下行可达 很高次数、 配置变更次数、 分类、 是否达标等, 并根据分析达标端口信息判 定细节计算得到每个新增字段的值, 供后续分类分析使用。 对所有用户, 新 增字段包括: 网元类型、 卡类型、 软件版本信息、 硬件版本信息, 还有固件 信息、 终端信息等可选字段。 并从网络管理系统对应的数据库中的网元板卡 信息表和用户信息表中同步相应的字段信息。 步骤 S910: 根据线路故障分类分析表中提到的 4种情况划分, 再细分上 下行 2个方向按照分类情况进行统计分析, 得到上下行各 4种分类情况。 将 这些分类信息同步到用户端口分析表的"分类"字段中, 由于分上下行, 因此 一个用户的分类属性中可能还有上行、 下行的多个分类情况。 步骤 S912: 根据每种故障分类情况的用户数量, 统计每种故障分类占本 次故障用户的百分比, 可以根据百分比高低确定需要进一步分析的方向。 也 可以直接选择某个故障分类方向进一步分析。 步骤 S914: 在选个某个故障分类情况后,按不同网元类型、不同卡类型、 不同硬件版本信息、 不同软件版本信息等字段统计其故障用户占本次故障用 户总数百分比(系列值 1 ), 以及其占所有网元类型、 卡类型、硬件版本信息、 软件版本信息的用户的百分比(系列值 2 )。 通常情况下, 如果系列值 1的某 项值的是系列值 2对应的某项值的 1.3倍以上基本上可以判断是与那项分类 有关。 通过查阅对应的用户历史运行参数和用户统计参数, 即可进一步确定 是否符合判断结果。 提供故障归类的分析方法对釆集汇总的数据进行分析、 故障预警和故障 排除, 从而进一步提高了批量解决故障的能力。 优选地, 在线路管理系统根据收集的参数信息进行故障分类之后, 还可 以包括以下处理: 线路管理系统通过单路端口诊断确认故障分类的正确性。 上述处理也可以不执行, 但是, 确认故障分类的正确率, 可以确定当前 分类的正确率, 在正确率较低的情况下, 可以适当调整分类策略, 根据调整 后的分类策略, 进行用户线端口故障分类。 图 10 是 居本发明优选实施例的数字用户线端口信息收集方法的流程 图。 如图 10 所示, 根据本发明优选实施例的数字用户线端口信息收集方法 可以包括以下处理 (步骤 S 1002-步骤 S 1014 ): 步骤 S 1002: 电信业务中心根据用户申请进行资源归还, 并相应制定业 务开通单, 其中, 业务开通单包括: 用户号码 (例如: 宽带上网帐号、 电话 号码等唯一号码)、用户端口号码(端口位置编号及其对应网元槽位端口号物 理位置, 以便网管下发申请)、 业务信息(端口的上下行速率、 最小脉冲噪声 保护要求、 目标噪声余度、 最大延时要求等), 以及其他相关信息。 步骤 S 1004: 可以在网管要求下获取返回指定用户端口的目前的策略信 息。 也可以 居策略分析结果上 ·ί艮网管中心更新某个用户端口的釆集策略。 在具体实施过程中, 上述策略信息包括但不限于: 监控状态、 监控模式、 监控对象、 釆集触发模式以及其他策略信息。 其中, 监控状态, 用来标识该用户端口是否需要进行釆集, 如果设置为 真则需要在网元上在釆集触发模式下根据监控对象进行参数的信息收集。 一 般默认为真。 其中, 监控模式, 通常分为自动 (代码 - 1 )、 手工 (代码 0 )、 强制 1次 (代码 1 )或者强制 Ν次(代码 Ν )。 自动表示由线路管理系统自动调整监控 状态。 手工, 一般电信运维人员根据需要强制釆集或者不釆集用户端口的参 数信息。一般默认自动。 强制 Ν次, 是指执行 Ν次网元端口数据上传后变监 控模式变为自动且监控状态变为假(不监控),通常情况下也是手工下达指令, 可用于没有故障或者故障少的用户的复查。 其中, 监控对象, 表示在监控状态下监控什么类型的故障, 例如: 端口 不达标、 掉链等。 也可进一步细化监控参数为用户端口的性能统计参数。 对 每种类型或者参数可以进行二进制编码, 并通过 "或"操作实现同时监控多个 对象。 步骤 S 1006: 网络管理系统综合步骤 S 1002和步骤 S 1004的信息, 提取 出用户所在的网元并生成釆集策略, 并将指定的信息下发到指定网元。 步骤 S 1008: 网元才艮据网络管理系统下发的釆集策略更新到网元的釆集 策略数据库, 以便在端口事件触发时查询并釆取相应的釆集操作。 步骤 S 1010: 网元在端口的事件触发(例如: 建链、 掉链、 速率改变等) 时查询当前端口的釆集策略信息, 并根据釆集对象进行参数记录。 步骤 S 1012: 网元在需要的时候将各端口历史釆集对象的运行参数信息 上传到线路管理系统的数据库中, 供后续查询和分析使用。 步骤 S 1014: 线路诊断系统分析各端口历史釆集对象的运行参数信息, 调整釆集策略。 以端口不达标为例, 如果在某一批次收集或者某一个时间范 围内的历史数据中计算得到该端口的达标结果。 如果该端口的监控模式为自 动, 则监控状态在达标结果"达标"时设置假, 后续不进行收集; 监控状态在 达标结果"不达标 "时设置真, 需要进行收集。 如果该端口的监控模式为手工, 则监控状态保持不变。 达标结果的计算方法可以才艮据具体情况而定,例如,可以釆用如下方法, 但不限于该方法。 当用户平均上行实际连接速率≥ 上行配置速率 χ98 % ; 并且用户平均下 行连接速率≥ 下行配置速率 χ98%时, 确认用户端口速率达标; 否则, 则确认 端口为不达标。 在具体实施过程中, 可以进一步扩展或者 4爹改上述计算方法, 例如: ( 1 ) 对于次数较多的端口可以进行去除最高、 最氏实际速率的记录; 或者
( 2 ) 对每条记录计算是否达标, 然后每次统计时同一个端口的记录时 如果 80 %的达标则可以判断为达标。 或者
( 3 ) 可根据电信运营商要求定制达标计算公式。 在用户数字线端口信息釆集中, 端口信息包括: 网元如何记录端口不达 标和掉链这两种监控对象的端口信息 (也可根据需要进一步扩展监控对象), 以及线路管理系统如何收集网元的端口信息数据等。 综上所述, 借助本发明提供的上述实施例, 提供了一种数字用户线端口 信息收集方案, 对大量数字用户线接入复用器的端口信息的釆集, 端口信息 根据指定策略进行记录,大大提高了釆集效率并保证了实时数据的有效收集; 并且, 提供故障归类的分析方法对釆集汇总的数据进行分析、 故障预警和故 障排除, 从而进一步提高了批量解决故障的能力。 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 ^"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。
