Description

一种网络质量监控方法及装置 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种网络质量监控方法及装置。
背景技术
在无线局域网中，接入点(access point，AP)的吞吐量与网络质量有着密切的关系，AP的吞吐量降低时，网络质量也会变差。
通常，可以通过监控AP的吞吐量对网络质量进行监控。具体的，可以根据一些影响AP的吞吐量的参数建立AP的吞吐量模型，这些影响AP的吞吐量的参数可以包括但不限于空口容量(例如频段、带宽等影响空口容量)、设备容量(例如通信协议、多输入多输出MIMO的模式等影响设备容量)、AP的覆盖情况(例如接收信号强度等反映AP的覆盖情况)、干扰因素(例如AP之间的同频干扰率等)，该AP的吞吐量模型的输入为上述参数，输出为AP的吞吐量(即可以理解为AP的吞吐量阈值)。在实际应用中，网络质量监控装置可以获取无线网络中的AP的实际吞吐量以及上述参数，然后结合AP的吞吐量模型输出的AP的吞吐量阈值确定网络质量的情况，若AP的实际吞吐量小于AP的吞吐量阈值，则认为网络质量差。
然而，由于根据上述AP的吞吐量模型仅能确定由上述影响AP的吞吐量的参数引起的网络质量变化，其他问题引起的网络质量变化则无法进行监控，因此，可能使得网络质量检测效果不明显。
发明内容

本申请实施例提供的网络质量监控方法，由于网络质量监控装置可以根据其获取网络运行数据(包括AP的静态数据和多组动态数据)分别确定AP的多个信道效能值以及AP的信道效能基线，再根据AP的多个信道效能值以及AP的信道效能基线，确定AP所在的无线局域网的网络质量，又由于AP的信道效能值在一定程度上可以真实反映由于各种因素导致的网络质量的变化，因此本申请提供的网络质量监控方法能够实现对网络质量进行更加有效地监控。
在一种可能的实现方式中，上述一个采样周期中有效数据传输时间段可以为该采样周期内连续的时间段，该有效数据传输时间段也可以为该采样周期内，几个不连续的时间段组成的时间段，本申请实施例不作具体限定。

本申请实施例中，在一个采样周期内，信道效能值的定义为：

其中，tx_bytes为采样周期内AP发送的字节数，rx_bytes为采样周期内AP接收的字节数，tx_frame为AP发送数据所占的时间，rx_frame为AP接收数据所占的时间，pcu_cycle为采样周期，rx_busy为信道繁忙时间，rx_inf为信道干扰时间。由于
Figure PCTCN2019117958-appb-000002

在一种可能的实现方式中，AP的信道效能基线可以为AP的信道效能值的参考值与AP的吞吐量之间的变化关系的曲线，或者为AP的信道效能值的参考值与AP的信道利用率之间的变化关系的曲线，或者为AP的信道效能值的参考值与AP的同频干扰率之间的变化关系的曲线。并且，在一组静态数据下，结合数据统计特性，AP的信道效能值与上述三种动态参数之间的变化关系类似，即三种不同的动态参数对应的信道效能基线类似。

具体实施方式
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。

首先对本申请实施例提供的一种网络质量监控方法及装置中涉及的一些概念做解释说明。
吞吐量：指的是通信设备在单位时间内成功传输的数据量，在无线局域网中，AP的吞吐量在一定程度上可以反映该AP所在的无线局域网的网络质量，通常，运维人员接到用户报障以后，可以通过现场运行测试软件，测试AP的吞吐量是否达到吞吐量阈值，若AP的吞吐量小于吞吐量阈值，则判断网络质量比较差。
本申请实施例中，常见的影响网络质量的因素有：AP支持的频段以及带宽、AP支持的通信协议、AP的输入输出模式等，上述因素均可以使得无线局域网中的AP的吞吐量降低而导致网络质量变差。具体的；AP支持的频段以及带宽比较小时，使得AP的吞吐量比较低；AP 支持的通信协议不同时，AP的吞吐量也不同；AP的输入输出模式(例如MIMO模式)不同，则AP的吞吐量受影响。
此外，影响网络质量的因素还包括用户侧因素和空口侧因素，如下表1是示例的各种因素以及造成网络质量差的原因。
表1
Figure PCTCN2019117958-appb-000003
信道效能：用于衡量数据传输效果，可以用信道效能值衡量AP的信道效能，具体的，AP的信道效能值指的是AP在一个采样周期中用于传输数据的时间段(即AP真正传输数据的时间段，以下均称为有效数据传输时间段)内单位时间传输的数据量。例如，采样周期为1分钟，有效数据传输时间段为40秒，则在该40秒内每秒钟传输的数据量即为AP的信道效能值。本申请实施例中，AP的信道效能值也可以反映无线局域网的网络质量。
基于背景技术存在的问题，本申请实施例提供一种网络质量监控方法及装置，网络质量监控装置可以根据其获取网络运行数据，具体包括AP的静态数据和多个采样周期对应的多组动态数据，然后根据AP的多组动态数据确定AP的多个信道效能值，并且根据AP的静态数据确定AP的信道效能基线，再根据AP的多个信道效能值以及AP的信道效能基线，确定AP所在的无线局域网的网络质量，能够实现对网络质量进行更加有效地监控。
本申请实施例提供的网络质量监控装置也可以为分析器，主要用于对网络运行数据进行分析，得到AP的信道效能值，从而分析网络质量是否异常，上述分析器可以为一台服务器，下面结合图1具体介绍本申请实施例提供的服务器的各个部件。如图1所示，该服务器10可以包括：处理器11、存储器12和通信接口13等。
处理器11：是服务器10的核心部件，用于运行服务器10的操作系统与服务器30上的应用程序(包括系统应用程序和第三方应用程序)，例如处理器11通过运行该服务器上的网络质量监控的方法程序，对网络质量进行监控。
本申请实施例中，处理器11具体可以为中央处理器(central processing unit，CPU)，通用处理器，数字信号处理器(digital signal processor，DSP)，专用集成电路(application-specific integrated circuit，ASIC)，现场可编程门阵列(field programmable gate array，FPGA)或者其他可编程逻辑器件、晶体管逻辑器件、硬件部件或 者其任意组合，其可以实现或执行结合本申请实施例公开的内容所描述的各种示例性的逻辑方框，模块和电路；处理器也可以是实现计算功能的组合，例如包含一个或多个微处理器组合，DSP和微处理器的组合等。

本申请实施例中，存储器12具体可以包括易失性存储器(volatile memory)，例如随机存取存储器(random-access memory，RAM)；该存储器也可以包括非易失性存储器(non-volatile memory)，例如只读存储器(read-only memory，ROM)，快闪存储器(flash memory)，硬盘(hard disk drive，HDD)或固态硬盘(solid-state drive，SSD)；该存储器还可以包括上述种类的存储器的组合。
通信接口13：用于服务器10与其他设备进行通信的接口电路，通信接口可以为收发器、收发电路等具有收发功能的结构，本申请实施例中，通过服务器10上的通信接口13可以接收数据采集设备采集的网络运行数据等。
如图2所示，本申请实施例提供的网络质量监控方法可以包括S101-S104：
S101、网络质量监控装置获取网络运行数据。
其中，上述网络运行数据包括AP的静态数据和动态数据，该动态数据包括多个采样周期对应的多组动态数据。
本申请实施例中，通过网络中的数据采集设备可以采集网络运行数据，该网络运行数据可以分为日志、关键性能指标(key performance indicator，KPI)、告警数据以及配置数据等。网络质量监控装置可以从数据采集设备获取其采集的预设时间段内(也可以称为采样时间，该采样时间包括多个采样周期)的网络运行数据，例如KPI和配置数据，其中，KPI中包括动态数据，配置数据中包括静态数据。
本申请实施例中，在上述预设时间段的每个采样周期可以获取一组动态数据，每组动态数据包括AP的吞吐量、AP的信道利用率以及AP的同频干扰率。可以理解的是，动态数据是时序数据(即随着时间变化而变化的数据)。
在上述预设时间段内，获取的静态数据包括AP的类型、网络频段以及带宽，静态数据不随时间的变化而变化，AP的类型可以为AP7000、AP6000等，网络频段可以为2.4GHz(即吉赫兹，Ghz也就是十亿赫兹)、5GHz等，网络带宽可以为20MHz(即兆赫兹)、40MHz等
示例性的，如下表2为AP的静态数据的几组示例。
表2
AP的类型 网络频段 带宽
AP7000 5GHz 20MHz
AP6000 5GHz 40MHz
AP2000 2.4GHz 20MHz
S102、网络质量监控装置根据AP的多组动态数据，确定AP的多个信道效能值。
其中，AP的一个信道效能值为一个采样周期中有效数据传输时间段内单位时间传输的数据量。
可选的，本申请实施例中，上述一个采样周期中有效数据传输时间段可以为该采样周期内连续的时间段，该有效数据传输时间段也可以为该采样周期内，几个不连续的时间段组成的时间段，本申请实施例不作具体限定。
本申请实施例中，在一个采样周期内，信道效能值的定义为：
Figure PCTCN2019117958-appb-000004
其中，tx_bytes为采样周期内AP发送的字节数，rx_bytes为采样周期内AP接收的字节数，tx_frame为AP发送数据所占的时间，rx_frame为AP接收数据所占的时间，pcu_cycle为采样周期，rx_busy为信道繁忙时间，rx_inf为信道干扰时间。
上述公式(1)中，
Figure PCTCN2019117958-appb-000005
AP_tp为AP的吞吐量；
Figure PCTCN2019117958-appb-000006
AP_cu为AP的信道利用率，AP_cf为AP的同频干扰率。
综上可知，AP的信道效能值为：
AP_cp＝AP_tp/(AP_cu-AP_cf)      (2)
其中，AP_cp为AP的信道效能值，AP_tp为AP的吞吐量，AP_cu为AP的信道利用率，AP_cf为AP的同频干扰率。
下面通过实例详细说明AP的信道效能值的计算过程，假设采样周期为30秒(s)，在采样周期内AP的吞吐量为200兆比特每秒(Mbps)，AP的信道利用率为20％，AP的同频干扰率为0，根据上述公式(2)得到AP的信道效能值1000Mbps，该采样周期内，有效数据传输时间段为6s(即30s*20％)，上述AP的信道效能为1000Mbps可以理解为：在该6s内，AP平均每秒传输的数据量为1000兆比特(Mb)。
本申请实施例中，对于AP的每一组动态数据中的AP的吞吐量、AP的信道利用率以及AP的同频干扰率，采用公式(2)可以确定AP的一个信道效能值，如此，基于AP的多组动态数据，可以得到AP的多个信道效能值。
S103、网络质量监控装置根据AP的静态数据，确定AP的信道效能基线。
其中，信道效能基线用于指示AP的信道效能值的参考值与第一动态参数之间的变化关系，该第一动态参数为上述AP的动态数据中的一种，具体的，AP的信道效能基线可以为第一动态参数的多个值与对应的信道效能值的多个参考值形成的曲线。
本申请实施例中，在一种理想的测试环境下，例如在影响AP的吞吐量的因素(例如频段、带宽、接收信号强度、干扰率等等)为一种临界状态的环境下，固定一组静态数据不变，测试得到第一动态参数的多个值(例如信道利用率的多个值)对应的信道效能值的多个值(这些测试环境下得到的信道效能值以下均称为信道效能值的参考值，或者称为信道效能值的阈值)，从而将第一动态参数的多个值与对应的信道效能值的多个参考值形成的曲线作为确定网络质量的判断标准，称为信道效能基线。
具体的，不同的静态数据对应不同的信道效能基线，多条信道效能基线可以构成信道效能基线库，本申请实施例中，可以根据不同的静态数据下的测试数据(测试数据包括多个不同的第一动态参数及其对应的信道效能值的参考值)得到上述信道效能基线。示例性，以第 一动态参数为AP的信道利用率，以静态数据包括上述表2中的3组静态数据为例，在第一组静态数据下的测试环境中可以得到多个不同的信道利用率以及其对应的AP的信道效能值的参考值，从而得到第一组静态数据对应的信道效能基线；在第二组静态数据下的测试环境中可以得到多个不同的信道利用率以及其对应的AP的信道效能值的参考值，从而得到第二组静态数据对应的信道效能基线；依此类推，得到第三组静态数据对应的信道效能基线，从而构成AP的信道效能基线库。
可选的，本申请实施例中，还可以根据网络运行过程中的历史数据(该历史数据包括不同的静态数据，不同的静态数据下的多个不同的第一动态参数及其对应的信道效能值的参考值)，采用学习算法学习得到上述信道效能基线。需要说明的是，根据上述历史数据得到AP的信道效能基线的方法与根据上述测试数据得到AP的信道效能基线的方法类似，此处不再赘述。
本申请实施例中，可以在网络质量监控装置上预先配置信道效能基线库，该信道效能基线库中包括AP的多组静态数据对应的多条信道效能基线，一组给定的AP的类型、网络频段以及带宽对应一条信道效能基线，其中，一个第一动态参数可以对应信道效能基线上的一个信道效能值，该信道效能基线上的信道效能值可以作为AP的信道效能值的参考值(也可以称为AP的信道效能值的阈值)，也就是说，一条信道效能基线可以反映AP的信道效能值随第一动态参数的变化趋势。
可选的，本申请实施例中，AP的信道效能基线可以为AP的信道效能值的参考值与AP的吞吐量之间的变化关系的曲线，或者为AP的信道效能值的参考值与AP的信道利用率之间的变化关系的曲线，或者为AP的信道效能值的参考值与AP的同频干扰率之间的变化关系的曲线。
可以理解的是，在一组静态数据下，结合数据统计特性，AP的信道效能值的参考值与上述三种动态参数之间的变化关系类似，即三种不同的动态参数对应的信道效能基线类似。
本申请实施例中，若上述第一动态参数为AP的信道利用率，示例性的，假设AP的类型为AP7000，网络频段为5GHz，带宽为20MHz，图3为在该组静态数据下，AP的信道效能基线的一种示意图。
S104、网络质量监控装置根据AP的多个信道效能值和AP的信道效能基线，确定AP所在的无线局域网的网络质量。
本申请实施例中，网络质量监控装置可以根据AP的多个信道效能与AP的信道效能基线的分布关系，确定AP所在的无线局域网的网络质量。
本申请实施例提供的网络质量监控方法，网络质量监控装置可以根据其获取网络运行数据(包括AP的静态数据和多组动态数据)分别确定AP的多个信道效能值以及AP的信道效能基线，再根据AP的多个信道效能值以及AP的信道效能基线，确定AP所在的无线局域网的网络质量，由于AP的信道效能值在一定程度上可以真实反映由于各种因素导致的网络质量的变化，因此本申请提供的网络质量监控方法能够实现对网络质量进行更加有效地监控。
可选的，本申请实施例中，若上述第一动态参数为AP的信道利用率，上述网络质量监控装置获取了多组动态数据，每组动态数据中包括一个信道利用率，如此网络质量监控装置获取了多个信道利用率，该多个信道利用率分别对应多个信道效能值，进一步的，将AP的每个信道利用率与对应的AP的每个信道效能值组成的二元组体现在AP的信道效能值与信道利用率的坐标分布图中。示例性的，图4所示的坐标分布图中，横坐标为AP的信道利用率，纵坐标为AP的信道效能值，其中，曲线l1为上述AP静态数据对应的AP的信道效能基线，假设 网络质量监控装置获取了50组动态数据，即获取了50个信道利用率，则对应50个信道效能值，可以组成50个信道利用率与信道效能值的二元组，这50个二元组在该坐标分布图中的分布情况可以参见图4。
需要说明的是，以下实施例中，以第一动态参数为AP的信道利用率为例，具体介绍网络质量监控装置确定AP所在的局域网的网络质量的方法。
结合图2，如图5所示，在一种实现方式中，上述S104可以通过S1041a-S1041b实现：
S1041a、AP的多个信道效能值中，小于信道效能基线对应的信道效能值的信道效能值数量占AP的信道效能值的总数量的比例大于或者等于预设比例，则网络质量监控装置确定AP所在的无线局域网的网络质量差。
S1041b、AP的多个信道效能值中，小于信道效能基线对应的信道效能值的信道效能值数量占AP的信道效能值的数量的比例小于预设比例，则网络质量监控装置确定AP所在的无线局域网的网络质量正常。
本申请实施例中，结合上述图3，信道效能基线上对应的纵坐标为信道效能值的参考值，上述AP的多个信道效能值中，对于小于信道效能基线对应的信道效能值的信道效能值，说明在对应的信道利用率下，在有效数据传输时间段内单位时间传输的数据量比较小；AP的多个信道效能值中，对于大于信道效能基线对应的信道效能值，说明在对应的信道利用率下，在有效数据传输时间段内单位时间传输的数据量比较大。
可以理解的是，信道效能值可以衡量网络质量，本申请实施例中，在AP的多个信道效能值中，小于信道效能基线对应的信道效能值的信道效能值数量所占的比例大于或者等于预设比例，说明数据传输的效果比较差，则网络质量监控装置确定AP所在的无线局域网的网络质量差。在AP的多个信道效能值中，小于信道效能基线对应的信道效能值的信道效能值数量所占的比例小于预设比例，说明数据传输的效果比较好，则网络质量监控装置确定AP所在的无线局域网的网络质量正常。
结合图2，如图6所示，在另一种实现方式中，上述S104可以通过S1042a-S1042b实现：
S1042a、AP的多个信道效能值中，连续小于信道效能基线对应的信道效能值的信道效能值数量大于或者等于预设数量，则网络质量监控装置确定AP所在的无线局域网的网络质量差。
S1042b、AP的多个信道效能值中，连续小于信道效能基线对应的信道效能值的信道效能值数量小于预设数量，则网络质量监控装置确定AP所在的无线局域网的网络质量正常。
本申请实施例中，在AP的多个信道效能值中，连续小于信道效能基线对应的信道效能值的信道效能值数量大于或者等于预设数量，说明数据传输的效果比较差，则网络质量监控装置确定AP所在的无线局域网的网络质量差。在AP的多个信道效能值中，连续小于信道效能基线对应的信道效能值的信道效能值数量小于预设数量，说明数据传输的效果比较好，则网络质量监控装置确定AP所在的无线局域网的网络质量正常。
结合图2，如图7所示，在又一种实现方式中，上述S104可以通过S1043a-S1043b实现：
S1043a、第一距离与AP的信道效能值的数量的比值大于预设比值，则网络质量监控装置确定AP所在的无线局域网的网络质量差。
其中，第一距离为AP的多个信道效能值中，小于信道效能基线对应的信道效能值的所有信道效能值与信道效能基线对应的信道效能值之间的距离之和。
S1043b、第一距离与AP的信道效能值的数量的比值小于或者等于预设比值，则网络质 量监控装置确定AP所在的无线局域网的网络质量正常。
本申请实施例中，上述第一距离与AP的信道效能值的数量的比值可以反映AP的信道效能值小于信道效能基线对应的信道效能值的程度，当第一距离与AP的信道效能值的数量的比值大于预设比值，说明数据传输的效果比较差，则网络质量监控装置确定AP所在的无线局域网的网络质量差。当第一距离与AP的信道效能值的数量的比值小于或者等于预设比值，说明数据传输的效果比较好，则网络质量监控装置确定AP所在的无线局域网的网络质量正常。
可以理解的是，本申请实施例中，信道效能基线为AP的信道效能值的参考值与AP的吞吐量之间的变化关系的曲线时，或者信道效能基线为AP的信道效能值的参考值与AP的同频干扰率之间的变化关系的曲线时，网络质量监控装置根据确定AP所在的局域网的网络质量的方法可以参见上述S1041a-S1041b或S1042a-S1042b或S1043a-S1043b，此处不再详述。
