Description

一种检测电调天线连接线序的方法和装置 技术领域
本文涉及但不限于通信技术，尤指一种检测电调天线连接线序的方法和装置。
背景技术
在无线通信系统中，有许多无线关键技术是和天线配置密不可分的。例如多输入多输出技术(Multiple-Input Multiple-Output，MIMO)，指在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收，若每个发射接收天线间的通道响应独立不相关，则多入多出系统可以创造多个并行空间信道，从而改善通信质量。要做到多天线传输系统有较低的空间相关性，在应用中，一般在天线配置时使用正交极化天线或有足够空间间隔的多个非极化天线等。
在无线网络中，最常用的是正交极化天线(也可称为双极化天线)，它有两个端口，分别对应+45°和-45°极化阵列。对于一面双极化天线，它和基站连接时不会产生连接线序上的异议。但是，当具有多通道的基站，比如2T4R基站(2个发射通道，4个接收通道)、4T4R基站(4个发射通道，4个接收通道)等基站，与多面双极化天线连接时，就会存在连接线序问题。例如对于2T4R基站，下行要工作在TM3工作模式(多用户MIMO的双流模式)下，就需要基站的两个发射通道连接到同一面互相正交的±45°极化天线上，确保发射通道间的弱相关性的要求。这样，终端在信号满足要求时能够选择进入高速率的TM3模式。如果两个发射通道接到了同一个极化方向的天线上，会因为发射通道间相关性太强，导致终端无法工作在TM3模式，数据吞吐率性能减半，造成无线网路的关键指标(Key Performance Indicator，KPI)恶化，覆盖范围缩水、掉话率提高、切换成功率降低等，最终影响网络质量。
目前在无线网络建设和维护中，天馈系统的问题往往不易发现和定位， 一般通过人工上站检查，导致耗费大量的人力物力，增加了工程与维护成本。

本发明的实施方式
下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下， 可以以不同于此处的顺序执行所示出或描述的步骤。
本发明实施例中，当调节或扫描电调天线的电下倾角时，由于天线振子间的有源互耦和电调单元中移相器S参数(注：S参数是建立在入射波、反射波关系基础上的网络参数，适于微波电路分析，以器件端口的反射信号以及从该端口传向另一端口的信号来描述电路网络)发生变化，造成电调天线的驻波或反向功率发生变化，然后通过和其连接的基站来检测这个驻波或反向接收功率变化，从而判断基站发射端口和天线天馈端口之间的连接关系。
本发明实施例提供一种自动检测电调天线连接线序的方法，所述方法可应用于基站，如图1所示，该方法包括：
步骤100、将基站配置为下行模拟加载模式。
可选的，下行模拟加载模式包括：无需真实用户设备接入基站，基站模拟用户业务数据单向的发送射频信号，经过射频线缆(跳线)传输到天馈端口，通过天线振子辐射到空间。
需要说明的是，在本实施例中，步骤100为可选的，可以不执行步骤100直接执行步骤101。
步骤101、通过调节天线的电调单元调节所述电调单元对应的电调天线的电下倾角，并通过天线端口采集对应n个电下倾角的反射信号的预设参数，n为大于2的正整数。
可选的，电调单元调节所述电调单元对应的电调天线的电下倾角，是按照国际天线标准接口及协议(Aircraft Service International Group，ASIG)进行的；基站的ASIG接口通过一个远端控制单元(Remote Control Unit，RCU)和天线的电调单元连接；电调单元和天线内部移相器部件连接。
基站网管中心通过基站发送指令给远端控制单元RCU，RCU接收指令后，启动内嵌电机带动天线电调单元，通过移相器部件改变天线振子的相位，使得每个振子辐射场强的垂直分量和水平分量的幅值大小发生改变，相应的空间合成的辐射方向图发生改变，最后达到对天线的垂直方向图下倾角的改变。
一般的，一个双列极化电调天线都具有一个独立的电调单元，这样对于 N列的天线系统，可以当做N/2面双极化天线对待，并且具有N/2个独立电调单元。
对于N列天线，依次对所属的第m(m＝1..N/2)个电调单元调节，使得电下倾角按照一定的角度步进遍历，基站分别采集每个电调单元在不同电下倾角时，其发射通道对应的反射信号(也可称为反向接收信号)的预设参数，多次采样并统计记录，可选的，预设参数可以是基站发射通道的驻波比或反向接收功率，这样可以得到一个关于电调单元、电下倾角和基站发射通道驻波比或反向接收功率的数据表格。
天线电下倾角的遍历范围，一方面要考虑能表征检测的动态范围，同时要考虑对整个网络信号覆盖影响，所以电下倾角的遍历范围可以根据实际条件和对网络影响来权衡决定。
步骤102、根据所述n个电下倾角的反射信号的预设参数的数值以及预设数理统计算法计算所述预设参数的统计学特征参数，所述统计学特征参数用于表征所述预设参数的离散程度。
可选的，所述预设数理统计算法包括方差算法；相应的，
所述统计学特征参数包括方差；
步骤102可以为：根据所述n个电下倾角的反射信号的预设参数的数值以及方差算法计算所述预设参数的方差。
需要说明的是，对于n个电下倾角的每一个电下倾角，可以多次采集同一个电下倾角的反射信号的预设参数的值然后取其平均值作为该电下倾角反射信号的预设参数的值，然后对这组n个平均值根据预设数理统计算法(例如方差算法)计算方差，该方差能体现该组n个平均值的离散程度。
示例性的，假设n＝4且第1至4个电下倾角分别为1°、3°、5°、7°，采集该四个电下倾角对应的四个反射信号的驻波比的值(可以是对每个电下倾角采集m次取平均)，然后计算这四个值的方差，该方差能体现四个平均值的离散程度。
步骤103、当所述统计学特征参数的值大于预设阈值时，确定所述电调天线与所述基站之间的连接线序正确。
可选的，所述预设阈值是根据所述电调天线与所述基站之间正确的连接线序确定的。
需要说明的是，本发明实施例中所述的预设阈值可以是技术人员根据实际工作经验测量总结得到的。
本发明实施例提供的一种自动检测电调天线连接线序的方法，通过电调单元调节所述电调单元对应的电调天线的电下倾角并通过天线端口采集对应n个电下倾角的反射信号的预设参数，n为大于2的正整数；根据所述n个电下倾角的反射信号的预设参数的数值以及预设数理统计算法计算所述预设参数的统计学特征参数，所述统计学特征参数用于表征所述预设参数的离散程度；当所述统计学特征参数的值大于预设阈值时，确定所述电调天线与基站之间的连接线序正确。通过远程自动检测当前基站和天线的连接线序从而发现和定位天馈系统的问题，无需人工上站检查，可有效降低工程与维护成本。

为了使本领域技术人员能够更清楚地理解本发明提供的技术方案，下面通过具体的实施例，对本发明提供的技术方案进行详细说明：
实施例1
在本实施例中结合上述方法实施例，对自动检测电调天线连接线序的方法具体描述如下：
如图3a所示，以一种2T4R基站和两面双极化电调天线组成的系统为例。
具体的连接关系如下：双极化天线由天线振子组201、移相器网络202和电调单元203、204组成。电调单元203、204设置为通过电调接口205和外置远程控制单元(RCU)206的控制口相连，RCU有级联功能，通过级联口可以级联另一个RCU设备；远程控制单元(RCU)206的控制端通过信号线缆和基站的ASIG接口207相连；基站的射频端口(CH1/CH2/CH3/CH4)分别和极化天线的天馈端口(ANT1/ANT2/ANT3/ANT4)通过射频线缆连接，这里定义CH1、CH2、CH3和CH4分别对应基站的收发通道TX1/RX1、接收通道RX3、接收通道RX4和收发通道TX2/RX2；根据2T4R基站的配置要求，发射通道和天线端口的线序要求ANT1连接CH1(TX1/RX1)，ANT2连接CH4(TX2/RX2)。最后，基站网管中心和基站相连，对基站和电调天线进行配置。
本实施例具体步骤包括如下：
步骤1、基站工作在下行模拟加载模式。
通过基站网管中心远程配置基站为下行模拟加载模式，模拟用户业务下发数据，目的是为了体现基站进行驻波比或反向功率测量的真实场景。
步骤2、配置电调天线的电下倾角，采集并统计发射通道CH1和CH4的驻波比或反向接收功率
基站工作正常后，基站网管中心通过基站的ASIG接口207给远程控制单元206下发送设置电下倾角的指令，远程控制单元206接到指令后，电机转动带动天线的电调单元203、204，完成对移相器网络202的操作，从而改变天线振子组201的相位，实现对天线的垂直方向图下倾角的改变。
电调单元每调节一次电下倾角，采集并统计发射通道CH1和CH4的驻波比(VSWR_TX1/VSWR_TX2)或反向接收功率(REV_TX1/REV_TX2)，按照一定的步进(以1度为例)遍历电下倾角。可得到分别电调A、电调B变化时发射通道CH1和CH4分别对应的驻波比或反向接收功率。例如表1所示。
表1
步骤3、计算电下倾角变化时，发射通道驻波比或反向接收功率的统计
Figure PCTCN2016072744-appb-000001
学特征参数。
对步骤2中得到的表格做合理的数据处理分析，可以得到在电调单元(以下简称为电调)A调节电下倾角时，发射通道CH1和CH4的驻波比或反向接收功率的统计学特征参数(例如方差)△TX1_A和△TX2_A；电调B调节电下倾角时，发射通道CH1和CH4的驻波比或反向接收功率的统计学特征参数为△TX1_B和△TX2_B。上述统计学特征参数能真实反映是由于电下倾角变化引起的。
步骤4、根据天线线序配置要求和预设阀值，对步骤3得到的4个统计学特征参数进行判定，给出天线线序正确性判断。
根据本系统设置一个预设阀值X，和步骤3得到的4个变化量比较，得到如下结果，见表2：
ΔTX1_A≥X ΔTX1_B≥X ΔTX2_A≥X ΔTX2_B≥X
是 否 是 否
表2
可选，按照表3所示的2T4R天线配置要求，

CH1<—>电调A -- CH4<—>电调A --
表4
根据上述判断，CH1和CH4和同一个电调单元A下的两列极化天线阵列连接，图3a中的连接和2T4R系统的天线配置要求相符，因此判定电调天线与基站之间的连接线序正确。
实施例2

Figure PCTCN2016072744-appb-000003

Figure PCTCN2016072744-appb-000004
Figure PCTCN2016072744-appb-000005
表6
根据上述判断，CH1和电调A所在的天线阵列连接，CH4和电调B所在的天线阵列连接。而天线配置要求两个发射通道必须在同一面天线上，图3b中的连接和2T4R系统的天线配置要求不符合，因此判定电调天线与基站之间的连接线序错误。
实施例3
如图4a所示网络配置系统，同样按照实施例1所描述的步骤1、2、3、4，可以得到如下结果，见表7：
表7
可选，按照如下所示的4T4R天线配置要求，见表8，

Figure PCTCN2016072744-appb-000010
表10
可选的，如实施例3中所示的4T4R天线配置要求，可以做出以下判定，见表11：

表11
根据上述判断，CH1、CH3和电调A所在的天线阵列连接，CH2、CH4和电调B所在的天线阵列连接。图4b中的连接连接和4T4R系统的天线配置要求不符，因此判定电调天线与基站之间的连接线序错误。
