Description

基站天线口底噪的测量方法、 装置及系统
技术领域
本发明涉及移动通信领域, 尤其涉及一种基站天线口底噪的测量方法、 装置及系统。
背景技术
良好有序的无线环境是移动通信系统中基站正常运行的基础。 判断基站 的无线环境优劣的方法是测量、 分析基站天线口底噪。 基站天线口是指基站 天线的空间接口, 在天线口无信号和干扰时, 底噪就是空间热噪声。
现有技术中, 测量基站天线口底噪的常用方法包括:
方法一、 网络维护人员用仪器到基站天线口实地测量;
方法二、 在基站系统已配置的载波没有终端用户时, 通过测量该载波的
RSSI (接收信号强度指示, Received Signal Strength Indication )值测量基站天 线口底噪的信号强度。
现有方法二中, 基站收发信机的测量原理如图 1所示, 接收到的基站天 线口多载波信号经反向接收机链路放大调整, 传输到 ADC (模数转换器) , 经 ADC变换成对应的宽带数字信号,再将宽带数字信号分路输出给各个基带 载波处理链路; 其中每个基带载波处理链路中各有一个 "数字混频器以及 NCO ( numerical controlled oscillator, 数字控制振荡器) 电路" , 将宽带数字 信号变频成所需要的基带数字信号, 再经基带载波滤波器, 输出载波基带数 字信号, 图 1中的基带载波 1、 基带载波 2、 基带载波 3、 基带载波 4、 基带 载波 5、 基带载波 6, 几路载波基带数字信号分别输出给 RSSI测量模块, 分 别计算出各载波基带数字信号的 RSSI值, 并上报给 OMC (操作维护中心)。 如果基站天线口的一载波内没有终端用户即无用户信号, 则该载波对应的载 波基带数字信号即为空间底噪信号,该载波的 RSSI值即为基站天线口底噪的 信号强度。 现有技术中, 第一种测量基站天线口底噪的方法, 需要网络维护人员实 地测量, 需要耗费大量人力物力; 第二种测量基站天线口底噪的方法, 需要 在基站系统中已配置的载波没有终端用户时进行, 并非实时测量。 但是在实 际应用中, 实时测量基站天线口底噪的信号强度对于实时监测、 维护基站的 无线环境和基站系统的高性能正常运行具有重要意义。
因此, 如何实时测量基站天线口底噪的信号强度成为现有技术中亟待解 决的技术问题。

本发明的较佳实施方式
为了实现对基站天线口底噪的实时测量, 达到实时监测、 维护基站的无 线环境和基站系统的高性能正常运行的目的, 本发明实施例提供一种基站天 线口底噪的测量方法、 装置及系统。 以下结合说明书附图对本发明的优选实施例进行说明, 应当理解, 此处 所描述的优选实施例仅用于说明和解释本发明, 并不用于限定本发明, 并且
本发明人发现: 基站系统的一个特点是多载波设计、 由软件灵活配置应 用; 但在基站系统的实际应用中, 大多数运营商并没有充分使用到基站系统 的满配多载波能力。 例如, 针对目前常见的 CDMA ( Code Division Multiple Access, 码分多址)基站, 基站双工器的带宽一般为 11M, 基站收发信机满 配为 6个载波; 但在 CDMA基站的实际应用中, 运营商最常用的是两载波、 4载波, 很少用到满配 6载波。 对于 6载波 CDMA基站来说, 基站天线口的 无线环境具有如下特点: 基站天线覆盖的小区无线环境中, 基站天线可接收 处理 6载波带宽的信号, 但实际应用配置的载波数小于满配载波数, 即基站 天线口中具有部分空闲载波接收非有用信号。 依据无线电管理规定, 在基站 天线覆盖的区域内, 即基站双工器占用的 11M CDMA应用频段内, 不允许有 其它无线信号发射。因此依据无线电管理规定可知:在基站双工器占用的 11M CDMA应用频段中未配置使用的空闲载波内, 只有底噪(空间热噪声) 。 底 噪(空间热噪声)在 11M CDMA应用频段内均匀分布, 并通过基站天线口进 入基站收发信机。
基于以上分析, 本发明实施例提供了一种基站天线口底噪的测量方法, 如图 2所示, 包括:

5306、 OMC将基站收发信机上报的待测空闲载波频点的 RSSI值, 作为 基站天线口底噪的信号强度; S307、 OMC监测已配置的载波的终端用户数量,在监测到一载波没有终 端用户时, 获取该载波的 RSSI值, 并将获取到的 RSSI值作为基站天线口底 噪的信号强度。 本发明实施例提供的基站天线口底噪的测量方法适用于各种网络制式, 为了便于描述, 本发明实施例以 CDMA系统为例进行说明, CDMA系统中 的基站可以称为 CDMA基站。 假设 CDMA基站的基站收发信机满配为 6个 载波, 基站双工器的频段为 824MHz-835MHz, 已配置的载波数为 4, 已配置 的载波的频点号分别为 37、 78、 119、 160。 CDMA基站天线口底噪的测量方 法, 包括如下步骤:
步骤 1、 OMC根据预先配置的基站收发信机的载频配置信息, 判断已 配置的载波数是否小于可配置的最大载波数(最大能力) , 由于已配置的载 波数为 4, 而可配置的最大载波数为 6, 因此执行步骤 2;
步骤 2、 确定可配置使用却未配置使用的空闲载波频点;
在步骤 2的具体实施中, 包括如下子步骤:
步骤 21、 基于 CDMA系统的频点计算公式, 根据已配置的载波的频点 号 37、 78、 119、 160, 确定每一个已配置的载波的中心频率;
具体如公式 [1]所示: (N) = 825 + 0.03N; 825.03≤ (Λ ≤ 848.31; Ne (1, 777)
F(N) = 825 + 0.03(N - 1023); 824.7 < (N) < 825; Ne (1013, 1023) ^」 每一个已配置的载波的中心频率分别为: 826.11MHz、 827.34MHz, 828.57MHz, 829.80MHz;
步骤 22、 根据计算出的已配置的载波的中心频率 ( 826.11MHz、 827.34MHz、 828.57MHz、 829.80MHz ) 、 以及基站双工器的频段信息 ( 824MHz-835MHz ) , 计算基站双工器频段 824MHz-835MHz内的空闲载波 的频点范围;
由于各载波的带宽为 1.23MHz,因此可得到空闲载波的频点范围如公式 [2]所示:
(829.8 + 1.23) < F(n\) = (825 + 0.03«1) < (835 - 1.23), n\ G (1, 777) [2]
步骤 23、根据基站双工器频段 824MHz-835MHz内的空闲载波的频点范 围、 以及预先规划的可配置使用的载波频点, 确定可配置使用却未配置使用 的空闲载波频点;
步骤 3、 从确定出的各空闲载波频点中, 选择距离已配置的载波间隔最 大的空闲载波频点作为待测空闲载波频点;
根据基站双工器的频段信息 824MHz-835MHz, 已配置的载波中最小中 心频率距离基站双工器频段下边界的间隔为(826.11Μ-824Μ)=2.11ΜΗζ; 已配 置的载波中最大中心频率距离基站双工器频段下边界的间隔为 (835M-829.80Μ)=5.20ΜΗζ ,也就是说距离已配置的载波间隔最大的空闲载波 频点在基站双工器频段的高端, 选择待测空闲载波频点 "1为 292;
步骤 4、 同步配置参数《1和3(«1)到基站收发信机中;
待测空闲载波频点《1为 292 , 并待测空闲载波频点《1对应的基带载波滤 波器的带宽 («1) = 1 ;
具体地,将测量底噪信号强度用的载波频点《1及对应的基带载波滤波器 的带宽参数 (《1)配置参数, 同步到基站收发信机中, 即根据 OMC应用配置 参数, 设置底噪信号强度测量的电路参数;
步骤 5、 基站收发信机测量待测空闲载波频点 的 RSSI值;
步骤 6、基站收发信机上报测量得到的待测空闲载波频点 fA的 RSSI值; 步骤 7、 OMC将待测空闲载波频点 的 RSSI值, 作为基站天线口底噪 的信号强度。 基于同一发明构思, 本发明实施例中还提供了一种基站天线口底噪的测 量装置,由于该测量装置解决问题的原理与基站天线口底噪的测量方法相似, 因此该装置的实施可以参见方法的实施, 重复之处不再赘述。
