Description

数字用户线路的优化方法及装置 技术领域
本文涉及但不限于通信技术领域，尤指一种数字用户线路的优化方法及装置。
背景技术
DSL(Digital Subscriber Line，数字用户线路)技术是基于普通电话线的宽带接入技术，它在同一铜线上分别传送数据和语音信号。迄今为止，世界多国已相继开发出了ADSL(Asymmetric Digital Subscriber Line，非对称数字用户线路)、VDSL(Very High Speed Digital Subscriber Line，超高速数字用户线路)、SHDSL(Single-pair High bit rate Digital Subscriber Line，单对线高速数字用户线)、ADSL2、ADSL2+、VDSL2等多种不同类型的DSL接入技术。这些统称为“xDSL”的DSL接入技术的基础系统架构与原理基本上是相似的，所不同的只是这几种技术在信号传输速率与距离、具体实现方式及上、下行速率的对称性等方面有所区别而已。从上、下行数据速率的对称性与非对称性方面来看，DSL可分为对称DSL与非对称DSL技术两大类。
由于DSL所使用的铜线是非屏蔽的双绞线线对，线对间的电磁干扰会导致一对双绞线上的信号对另外一对双绞线上的信号产生干扰，即串扰。此外，DSL线路还会受到脉冲噪声、视频干扰、信道衰减等多种干扰。线路中的一种或多种干扰会导致DSL线路出现延迟、丢包、错包，引起严重误码秒，甚至造成线路的异常掉线，从而影响用户的业务体验。
因此优化DSL线路，保证DSL线路的稳定性已然成为相关技术中面临的重大问题。而在相关技术中DSL网络运维过程中，却无法自动地对大批量的DSL线路实施稳定性评估与优化。

第一实施例
如图1所示，本发明实施例提供一种数字用户线路的优化方法，包括：
步骤11，获取多个网元下的数字用户线路以及所述数字用户线路的链路状态；
这里需说明的是，一个网元下存在有多个数字用户线路。数字用户线路的链路状态包括：链路连接Link Up以及链路断开Link Down。
步骤12，根据数字用户线路的链路状态对所述数字用户线路进行稳定性评估，确定待优化的数字用户线路；
本步骤中，可以利用数字用户线路异常掉线的频度算法对数字用户线路进行稳定性评估，确定待优化的数字用户线路。
这里，数字用户线路异常掉线是指在预设时间内数字用户线路的链路断开次数大于预设断开次数。比如，在一小时内数字用户线路的链路断开次数大于2次，则确定该数字用户线路异常掉线，也就是，该数字用户线路不稳定。
步骤13，根据所述待优化的数字用户线路的当前运行模板，创建与所述待优化的数字用户线路的建链速率对应的优化模板；
需要说明的是，待优化的数字用户线路的当前运行模板是不满足稳定性要求的运行模板。
创建的优化模板则是对当前运行模板的配置参数调整后的满足稳定性要求的模板。
具体如何创建优化模板可以采用本领域技术人员的熟知技术实现，并不用于限定本发明实施例的保护范围，这里不再赘述。
步骤14，根据所述优化模板对所述待优化的数字用户线路进行优化及监控处理。
本发明实施例的数字用户线路的优化方法，通过计算数字用户线路异常掉线的频度，实现对数字用户线路的稳定性评估，并通过创建的优化模板对待优化的数字用户线路实现优化与监控。提高了数字用户线路网络的运维效率及数字用户线路的稳定性，减低了线路的异常掉线率，提升了用户体验。
可选地，所述步骤11中获取多个网元下的数字用户线路包括：
步骤111，通过网管同步多个网元资源以及所述多个网元下的数字用户线路资源；
网元资源包括DSLAM设备，数字用户线路资源包括DSLAM设备的用户端口。

这里，系统通过数字用户线路上报的链路状态通知消息来获取数字用户链路的链路状态。

这里需要说明的是，待优化的数字用户线路的优化模板可按照稳定性的高低创建多个优化模板，该多个优化模板均可确保待优化数字用户线路的稳定性。
这里，信噪比裕度(Signal to Noise Ratio margin，SNR margin)是用来测量网路服务质量的，它表示了网络在噪涌的情况下无错误工作的能力，它是两个SNR值的差，一个是目前网络的信噪比，一个是在目前速度下刚好能维持可靠连接的信噪比。
脉冲噪声防护(Impulse Noise Protection，INP)，表示系统对脉冲噪声的防护能力，INP的数值表示了通过交织和前向纠错(FEC，Forward Error Correction)可以保护的最多受脉冲噪声破坏的离散多音调(DMT，Discrete Mulititone)调制或多载波DMT符号的数量。
本发明实施例中的优化模板中主要的配置参数包括信噪比裕度值以及脉冲噪声防护值，通过调整线路信噪比裕度以及脉冲噪声防护的配置，提高了线路工作的稳定性，降低了异常掉线的频度，同时在速率上基本没有造成不利影响，在一般用户配置速率稍有冗余的情况下，实际建立速率可以满足与用户签约的带宽承诺。
步骤142，对稳定性优化成功的数字用户线路进行短期监控下的优化处理；
这里需要说明的是，短期监控的监控周期可自行设置，比如一小时。

步骤1413，在所述当前运行模板与所述初始优化模板不一致时，将所述待优化的数字用户线路的线路模板配置为所述初始优化模板；
例如，维持待优化的数字用户线路的带宽不变，将待优化的数字用户线路的INP设置为16，将待优化的数字用户线路的目标信噪比裕度设置为15db。
步骤1414，根据所述初始优化模板对所述待优化的数字用户线路进行稳定性优化处理。
具体如何对待优化的数字用户线路进行稳定性优化处理可以采用本领域 技术人员的熟知技术实现，并不用于限定本发明的保护范围，这里不再赘述。

步骤14222，在所述异常掉线次数小于或等于预设掉线次数时，获取所述稳定性优化成功的数字用户线路的建链速率；
具体如何获取稳定性优化成功的数字用户线路的建链速率可以采用本领域技术人员的熟知技术实现，并不拥有限定本发明实施例的保护范围，这里不再赘述。

步骤14224，在所述建链速率小于预设建链速率时，通过依次选取所述稳定性优化成功的数字用户线路的调整优化模板，对稳定性优化成功的数字用户线路进行短期监控下的优化处理；其中，所述调整优化模板中的目标信噪比裕度值小于初始优化模板中的目标信噪比裕度值，所述调整优化模板中 的脉冲噪声防护值小于初始优化模板中的脉冲噪声防护值。
需要说明的是，调整优化模板为创建的多个优化模板中的一个，该调整优化模板相较于初始优化模板的稳定性稍差，但建链速率可提高到与用户签约的带宽速率，同时可保证该待优化的数字用户线路的稳定性。
步骤1423，在所述短期稳定的数字用户线路的短期监控次数大于或等于第一预设监控次数时，确定所述短期稳定的数字用户线路在短期监控下的优化成功。
可选地，本发明实施例中所述步骤143包括：

这里，预设周期可自行设置，比如一星期、两星期等。
可以通过判断优化成功的数字用户线路的建链速率是否大于用户SLA带宽，以及判断异常掉线率是否达标来确定优化成功的数字用户线路的稳定状态。
当优化成功的数字用户线路的建链速率大于用户SLA带宽，且异常掉线率达标(即异常掉线次数小于预设次数)时，确定优化成功的数字用户线路为稳定状态。
当优化成功的数字用户线路的建链速率小于或等于用户服务等级协议(SLA，Service-Level Agreement)带宽，异常掉线率不达标时，确定优化成功的数字用户线路为不稳定状态。
步骤1432，在所述稳定状态为稳定，且长期监控次数大于或等于第二预设监控次数时，确定所述短期监控下优化成功的数字用户线路在长期监控下的优化成功。

这里需要说明的是，待优化的数字用户线路的优化模板可按照稳定性的高低创建多个优化模板，该多个优化模板均可确保待优化数字用户线路的稳 定性。
这里，信噪比裕度(Signal to Noise Ratio margin，SNR margin)是用来测量网路服务质量的，它表示了网络在噪涌的情况下无错误工作的能力，它是两个SNR值的差，一个是目前网络的信噪比，一个是在目前速度下刚好能维持可靠连接的信噪比。
脉冲噪声防护(Impulse Noise Protection，INP)，表示系统对脉冲噪声的防护能力，INP的数值表示了通过交织和前向纠错FEC可以保护的最多受脉冲噪声破坏的离散多音调或多载波DMT符号的数量。
本发明实施例中的优化模板中主要的配置参数包括信噪比裕度值以及脉冲噪声防护值，通过调整线路信噪比裕度以及脉冲噪声防护的配置，提高了线路工作的稳定性，降低了异常掉线的频度，同时在速率上基本没有造成不利影响，在一般用户配置速率稍有冗余的情况下，实际建立速率可以满足与用户签约的带宽承诺。

需说明的是，优化模板的选取原则为稳定性优先。初始优化模板中目标信噪比裕度值和脉冲噪声防护值最大，其稳定性最高。
判断单元，设置为判断所述当前运行模板是否与所述初始优化模板一致；
这里，若不一致，则执行模板配置单元中的步骤；若一致，则删除该待优化的数字用户线路的线路信息，表明线路优化失败。
模板配置单元，设置为在所述当前运行模板与所述初始优化模板不一致时，将所述待优化的数字用户线路的的线路模板配置为所述初始优化模板；
优化处理单元，设置为根据所述初始优化模板对所述待优化的数字用户线路进行稳定性优化。

需说明的是，过去预设小时可自行设置，比如过去1小时，过去2小时等。

需要说明的是，调整优化模板为创建的多个优化模板中的一个，该调整 优化模板相较于初始优化模板的稳定性稍差，但建链速率可提高到与用户签约的带宽速率，同时可保证该待优化的数字用户线路的稳定性。
第一优化确定单元，设置为在所述短期稳定的数字用户线路的短期监控次数大于或等于第一预设监控次数时，确定所述短期稳定的数字用户线路在短期监控下的优化成功。
可选地，所述第三优化处理子模块还可包括：
