Description
技术领域technical field
本发明涉及移动通信技术领域，尤其涉及一种互调干扰定位方法、装置和系统。The present invention relates to the technical field of mobile communications, and in particular, to a method, device and system for locating intermodulation interference.
背景技术Background technique
随着移动通信网络业务量的增加，为保证单小区可用资源充足，提升系统容量，减少拥塞等异常事件对用户日常使用感知的不良影响，单小区多载频配置的应用日趋普遍，同时单载频功率也有明显的提升。但提升系统容量的同时，由于无线设备系统的非线性的作用，又不可避免地引入了互调干扰，互调干扰导致的同频干扰、区域无线环境底噪抬升影响了无线信号的信噪比，降低了信号质量，从而导致用户通话质量差、掉话等异常事件。With the increase of mobile communication network traffic, in order to ensure sufficient available resources in a single cell, improve system capacity, and reduce the adverse impact of abnormal events such as congestion on users' daily use perception, the application of multi-carrier frequency configuration in a single cell is becoming more and more common. The frequency power has also been significantly improved. However, while improving the system capacity, intermodulation interference is inevitably introduced due to the nonlinear effect of the wireless device system. The co-channel interference caused by the intermodulation interference and the increase of the noise floor of the regional wireless environment affect the signal-to-noise ratio of the wireless signal. , which reduces the signal quality, resulting in abnormal events such as poor call quality and dropped calls.
因此，现网优化中需要对产生互调干扰的基站进行定位，现有的技术方案主要包括：Therefore, in the optimization of the existing network, it is necessary to locate the base stations that generate intermodulation interference. The existing technical solutions mainly include:
1、通过网管统计干扰信号的电平强度，并根据一定时间内的电平强度计算干扰系数，干扰系数＝(BAND4+BAND5)/SUM(BAND1:5)，其中电平强度按照由弱到强的顺序被分为五个区间，而BAND1至BAND5分别为在一定时间出现位于该区间的电平强度的次数，如果计算出的干扰系数大于30％，则怀疑该位置存在互调干扰。1. Calculate the level strength of the interference signal through the network management, and calculate the interference coefficient according to the level strength within a certain period of time. The interference coefficient = (BAND4+BAND5)/SUM(BAND1:5), where the level strength is from weak to strong The order of , is divided into five intervals, and BAND1 to BAND5 are the number of times that the level intensity in this interval occurs at a certain time. If the calculated interference coefficient is greater than 30%, it is suspected that there is intermodulation interference at this location.
2、通过网管统计干扰信号的电平强度和话务量，如果存在话务量和干扰电平同时增加和减少，则怀疑该位置存在互调干扰。2. Calculate the level strength and traffic volume of the interference signal through the network management. If the traffic volume and the interference level increase and decrease at the same time, it is suspected that there is intermodulation interference at the location.
3、使用互调测试仪在干扰区域随机选择基站并测试互调值，如果互调值落在上行频带内，则该基站为该干扰区域的干扰源。3. Use an intermodulation tester to randomly select a base station in the interference area and test the intermodulation value. If the intermodulation value falls within the uplink frequency band, the base station is the interference source in the interference area.
前两种互调干扰定位方法是通过网管统计干扰信号的电平强度来实现，采用这种方法存在发现问题不及时，同时定位不准确的问题。主要表现在：首先，统计数据途径单一，干扰区域需人工判决，仅通过网管统计干扰信号的电平强度、人工判断互调干扰可能存在的区域；其次，统计对比数据不可控，判断数据需同期用户业务量有明显的变化；再次，从干扰类型分析，网管统计的干扰信号可能是由互调干扰、系统同邻频干扰、外来会议保密器(通过全频带阻塞干扰保证区域无线通信阻断)等多种干扰源引起的，无法自动从多种干扰源中筛选出互调干扰。The first two intermodulation interference positioning methods are realized by the network management statistics of the level strength of the interference signal. Using this method has the problems of not finding problems in time and inaccurate positioning at the same time. The main manifestations are: First, the statistical data channel is single, and the interference area needs to be manually determined. Only the level strength of the interference signal is calculated through the network management, and the area where the intermodulation interference may exist is manually determined; second, the statistical comparison data is uncontrollable, and the judgment data needs to be synchronized. There are obvious changes in user traffic; thirdly, from the analysis of interference types, the interference signals counted by the network management may be caused by intermodulation interference, system co-adjacent frequency interference, and foreign conference security devices (through full-band blocking interference to ensure regional wireless communication blocking) Intermodulation interference cannot be automatically screened out from various interference sources.
第三种互调干扰定位方法是使用互调测试仪现场排查，采用这种方式只能在干扰区域随机抽取疑似基站，无法自动确定具体干扰基站，目的性不强，效率低下，同样存在发现问题不及时，同时定位不准确的问题。The third intermodulation interference positioning method is to use the intermodulation tester to conduct on-site investigation. In this way, only suspected base stations can be randomly selected in the interference area, and the specific interfering base stations cannot be automatically determined. The purpose is not strong, and the efficiency is low. There are also discovery problems. Not in time, and at the same time locating inaccurate problems.
综上，现有的互调干扰定位方法存在定位精度差和时效性差的问题。To sum up, the existing intermodulation interference localization methods have the problems of poor localization accuracy and poor timeliness.

R＝32.4+20*log(D)+20*log(M)；R=32.4+20*log(D)+20*log(M);
其中，R为路径损耗值，单位为dBm；D为无线信号自由空间传播距离，单位为km；M为无线信号的频率，单位MHz。Among them, R is the path loss value, the unit is dBm; D is the free space propagation distance of the wireless signal, the unit is km; M is the frequency of the wireless signal, the unit is MHz.
将上述路损公式应用到本发明实施例中，R为确定出的干扰信号的路径损耗值，M为干扰信号的频率，D为干扰信号的传播距离。Applying the above path loss formula to the embodiment of the present invention, R is the determined path loss value of the interference signal, M is the frequency of the interference signal, and D is the propagation distance of the interference signal.
步骤13，获取该区域范围内的基站的频率组信息。Step 13: Acquire frequency group information of base stations within the area.
其中，现网中各基站的频率组可以预先在话务网管设备中预先存储，在确定出可能存在互调干扰的区域范围之后，从话务网管设备中获取该区域范围内的基站的频率组信息即可。Among them, the frequency group of each base station in the existing network can be pre-stored in the traffic network management device. After determining the area where intermodulation interference may exist, the frequency group of the base station in the area is obtained from the traffic network management device. information.
步骤14，根据获取的基站的频率组信息和确定出的干扰信号的频率，判断基站是否存在互调干扰。Step 14, according to the acquired frequency group information of the base station and the determined frequency of the interference signal, determine whether the base station has intermodulation interference.
具体的，步骤14可以但不限于按照如下方式实现：Specifically, step 14 can be implemented in the following manner but is not limited to:
根据获取的基站的频率组信息，确定基站可能存在的互调干扰频率；According to the acquired frequency group information of the base station, determine the possible intermodulation interference frequency of the base station;
对比确定出的可能存在的互调干扰频率和干扰信号的频率；Compare the determined intermodulation interference frequency and the frequency of the interference signal;
当确定出的可能存在的互调干扰频率和干扰信号的频率相同时，确定基站存在互调干扰。When the determined frequency of possible intermodulation interference is the same as the frequency of the interference signal, it is determined that the base station has intermodulation interference.
其中，确定基站可能存在的互调干扰频率时，可以根据获取的基站的频率组信息，利用预先设置的互调干扰公式来确定。Wherein, when determining the intermodulation interference frequency that may exist in the base station, it may be determined by using a preset intermodulation interference formula according to the acquired frequency group information of the base station.
互调分为3阶、5阶、7阶以及更高阶数的互调，由于较高阶数的互调的影响相对较小，因此一般情况下只关心3阶、5阶和7阶的互调。Intermodulation is divided into 3rd-order, 5th-order, 7th-order and higher-order intermodulation. Since the influence of higher-order intermodulation is relatively small, generally only the 3rd-order, 5th-order and 7th-order intermodulation are concerned. intermodulation.
最通用的3阶互调干扰公式：F(IM3)＝2*F1-F2；The most common 3rd-order intermodulation interference formula: F(IM3)=2*F1-F2;
其中，F1和F2为基站的频率组信息中包括的频点。Wherein, F1 and F2 are the frequency points included in the frequency group information of the base station.
但当基站的频率组信息中包括的频点较多的时候，不只有2个频点能够产生互调干扰，多个频点互相作用也能产生互调干扰，并落在频段内，这样就衍生出来另一个3阶互调干扰公式：F(IM3)＝F1+F2-F3。However, when there are many frequency points included in the frequency group information of the base station, not only two frequency points can generate intermodulation interference, but also multiple frequency points can interact with each other to generate intermodulation interference, which falls within the frequency band. Another 3rd-order intermodulation interference formula is derived: F(IM3)=F1+F2-F3.
5阶互调干扰公式：F(IM5)＝3*F1-2*F2；5th-order intermodulation interference formula: F(IM5)=3*F1-2*F2;
同样的，也能衍生出多个其它的5阶互调干扰公式：Similarly, several other 5th-order intermodulation interference formulas can be derived:
比如：F(IM5)＝2*F1+F2-2*F3或2*F1+f2-f3-f4。For example: F(IM5)=2*F1+F2-2*F3 or 2*F1+f2-f3-f4.
7阶互调干扰公式：F(IM7)＝4*F1-3*F2；7th-order intermodulation interference formula: F(IM7)=4*F1-3*F2;
同样的，也能衍生出多个其它的7阶互调干扰公式：Similarly, several other 7th-order intermodulation interference formulas can be derived:
F(IM7)＝3*F1+F2-3*F2或2*F1+2*F2-2*F3-F4或2*F1+F2+F3-2*F4-F5。F(IM7)=3*F1+F2-3*F2 or 2*F1+2*F2-2*F3-F4 or 2*F1+F2+F3-2*F4-F5.
本发明实施例中，通过扫频数据，确定受干扰区域的受干扰信息，受干扰信息包括：干扰信号的频率和电平强度，以及受干扰区域的位置信息，再根据受干扰信息以及预先设置的基站发射功率，确定可能存在互调干扰的区域范围，并获取该区域范围内的基站的频率组信息，最后根据确定出的干扰信号的频率和基站的频率组信息，判断基站是否存在互调干扰。本方法能够通过扫频数据自动定位出存在互调干扰的基站，定位精确及时，弥补了现有技术中互调干扰定位精度差和时效性差的缺点。In the embodiment of the present invention, the interfered information of the interfered area is determined by scanning the frequency data, and the interfered information includes: the frequency and level strength of the interfered signal, and the location information of the interfered area, and then according to the interfered information and preset According to the transmit power of the base station, determine the area where intermodulation interference may exist, and obtain the frequency group information of the base station in the area. Finally, according to the determined frequency of the interference signal and the frequency group information of the base station, determine whether the base station has intermodulation interference.
