一种确定终端位置的方法、装置及系统A method, device and system for determining terminal location

技术领域technical field

本发明涉及通信技术领域，尤其涉及一种确定终端位置的方法、装置及系统。The present invention relates to the field of communication technologies, and in particular to a method, device and system for determining the location of a terminal.

背景技术Background technique

移动定位业务是运营商向用户提供的与终端位置相关的业务。利用移动定位业务提供的终端位置信息，运营商可以开发出更多的增值业务。The mobile positioning service is a service related to terminal location provided by operators to users. Using the terminal location information provided by the mobile positioning service, operators can develop more value-added services.

运营商希望可以以尽可能低的成本引入移动定位业务，且不对现有网络进行较大改动。利用已有的测量报告(MR，Measurement Report)确定终端位置无需增加任何硬件，无需对现有的信令以及信令交互顺序进行任何修改，只需对基站控制器进行软件升级即可。因此，利用MR确定终端位置成为业界研究的热点。Operators hope to introduce mobile positioning services at the lowest possible cost without making major changes to existing networks. Using the existing measurement report (MR, Measurement Report) to determine the location of the terminal does not require any additional hardware, and does not require any modification of the existing signaling and signaling interaction sequence, only the software upgrade of the base station controller is required. Therefore, using MR to determine the location of the terminal has become a research hotspot in the industry.

目前，利用MR确定终端位置的方法包括：利用路测数据对无线网络的传播模型进行矫正，使用矫正后的传播模型计算定位区域的信号电平分布，根据计算结果建立基于预测的接收电平数据库，当接收到终端上报的MR后，根据终端上报的MR中的小区以及接收信号强度查找接收电平数据库，进而确定终端位置。At present, the method of using MR to determine the location of the terminal includes: using drive test data to correct the propagation model of the wireless network, using the corrected propagation model to calculate the signal level distribution in the positioning area, and establishing a prediction-based receiving level database based on the calculation results , after receiving the MR reported by the terminal, search the receiving level database according to the cells in the MR reported by the terminal and the received signal strength, and then determine the position of the terminal.

发明人在研究过程中，发现上述方法至少存在以下缺点：无线网络在实际中是实时变化的，而在上述方法中，无线网络的传播模型以及建立的基于预测的接收电平数据库是固定不变的，故由上述对应关系确定出的终端位置精度不高。In the process of research, the inventor found that the above method has at least the following disadvantages: the wireless network changes in real time in practice, while in the above method, the propagation model of the wireless network and the established reception level database based on prediction are fixed Therefore, the accuracy of the terminal position determined by the above correspondence is not high.

具体实施方式Detailed ways

为了使本发明实施例的特征、优点更加清楚，下面结合具体实施方式进行详细说明。In order to make the features and advantages of the embodiments of the present invention clearer, detailed descriptions will be given below in conjunction with specific implementation manners.

请参考图1，为本发明实施例一确定终端位置的方法示意图，可以包括以下步骤：Please refer to FIG. 1, which is a schematic diagram of a method for determining a terminal location according to Embodiment 1 of the present invention, which may include the following steps:

步骤101：获取接收电平数据库，所述接收电平数据库包括定位区域的每个栅格的特征信息，所述特征信息包括地理信息、小区信息以及电平信息；Step 101: Obtain a receiving level database, the receiving level database includes characteristic information of each grid in the positioning area, and the characteristic information includes geographical information, cell information and level information;

其中，所述定位区域是预先设定的定位业务可以应用的范围。所述栅格是对定位区域划分的单元格。Wherein, the positioning area is a range in which a preset positioning service can be applied. The grid is a cell that divides the positioning area.

步骤102：接收终端上报的测量报告MR；Step 102: receiving the measurement report MR reported by the terminal;

步骤103：将所述MR中的小区信息以及电平信息与所述接收电平数据库中的小区信息以及电平信息进行绝对值匹配以及相对值匹配；Step 103: Absolute value matching and relative value matching are performed between the cell information and level information in the MR and the cell information and level information in the receiving level database;

The value of the grid, the value indicates the degree of approximation between the geographic location represented by each grid and the location of the terminal, the terminal is located in the grid with the smallest value, and the geographic information is used to determine the The location of the terminal.

可以看出，在本发明实施例中，结合了绝对值匹配与相对值匹配的结果，根据绝对值匹配的权重以及相对值匹配的权重，当无线网络环境较为稳定时，主要由绝对值匹配确定终端位置，当无线网络环境时变时，由相对值匹配的结果对绝对值匹配的结果进行补偿，从而可以极大提高确定终端位置的定位精度。It can be seen that in the embodiment of the present invention, the results of absolute value matching and relative value matching are combined, and according to the weight of absolute value matching and the weight of relative value matching, when the wireless network environment is relatively stable, it is mainly determined by absolute value matching For the terminal position, when the wireless network environment changes with time, the result of the absolute value matching is compensated by the result of the relative value matching, so that the positioning accuracy of determining the terminal position can be greatly improved.

请参考图2，为本发明实施例二确定终端位置的方法示意图，可以包括以下步骤：Please refer to FIG. 2, which is a schematic diagram of a method for determining the location of a terminal according to Embodiment 2 of the present invention, which may include the following steps:

步骤201：利用路测数据对无线网络的传播模型进行矫正；Step 201: Using the drive test data to correct the propagation model of the wireless network;

步骤203：根据计算结果建立基于预测的接收电平数据库；Step 203: Establishing a prediction-based reception level database according to the calculation result;

按照实际需要将定位区域划分为各个栅格，每个栅格的边长表示实际距离，上述基于预测的接收电平数据库以每个栅格为单位，记录了每个栅格所代表的位置信息，终端在该位置可以接收到的信号的电平强度以及终端可以接收到的信号所属的小区。例如：每个栅格的边长表示的实际距离为100m，则一个栅格表示实际区域为100m*100m的正方形。Divide the positioning area into grids according to actual needs, and the side length of each grid represents the actual distance. The above-mentioned reception level database based on prediction records the position information represented by each grid in units of each grid , the level strength of the signal that the terminal can receive at this location and the cell to which the signal that the terminal can receive belongs. For example: the actual distance represented by the side length of each grid is 100m, and one grid represents a square whose actual area is 100m*100m.

接收电平数据库的每条记录包括位置信息与该位置的小区标识以及终端在该位置可以接收到的信号电平强度的对应关系。Each record in the receiving level database includes a correspondence between location information, a cell identifier at the location, and a signal level strength that the terminal can receive at the location.

步骤201至步骤203可以由安装了专用软件的装置(例如：计算机)执行。Steps 201 to 203 can be executed by a device (such as a computer) installed with dedicated software.

步骤204：基站控制器接收终端上报的MR；Step 204: the base station controller receives the MR reported by the terminal;

步骤205：基站控制器根据MR对定位区域的每个栅格进行绝对值匹配以及相对值匹配；Step 205: The base station controller performs absolute value matching and relative value matching on each grid of the positioning area according to the MR;

下面分别对绝对值配置与相对值匹配进行详细说明。The following describes the absolute value configuration and relative value matching in detail.

(1)绝对值匹配(1) Absolute value matching

无线网络中的每个地理位置均具有唯一的特征信息，这些特征信息包括：地理信息、小区信息以及电平信息，具体地，特征信息包括：该地理位置的经纬度、终端在该地理位置可以接收到的信号所属的小区以及终端在该地理位置接收到的信号的电平强度。由于基站控制器接收到的MR中包括终端在一个地理位置接收到的信号所属的小区，故本发明实施例以MR中各小区的电平强度为基准，对各小区的电平强度以及定位区域内每个栅格的预测接收信号电平进行绝对值匹配。Each geographic location in the wireless network has unique feature information, and the feature information includes: geographic information, cell information, and power level information. Specifically, the feature information includes: the longitude and latitude of the geographic location, the terminal can receive The cell to which the received signal belongs and the level strength of the signal received by the terminal at the geographic location. Since the MR received by the base station controller includes the cell to which the signal received by the terminal at a geographic location belongs, the embodiment of the present invention uses the level strength of each cell in the MR as a reference, and the level strength of each cell and the positioning area Absolute value matching is performed on the predicted received signal level of each grid.

绝对值匹配以MR为基准，针对每个栅格，可以包括以下几个步骤：Absolute value matching is based on MR, and for each grid, it can include the following steps:

1、从栅格所对应的信息中查找是否包含MR中的服务小区的信息，如果包含，进入下一步骤2，否则，流程结束，或者，直接进入步骤3，比较MR的下一个信息；1. Find whether the information corresponding to the grid contains the information of the serving cell in the MR, if yes, go to the next step 2, otherwise, the process ends, or directly go to step 3, and compare the next information of the MR;

2、判决该栅格所对应的服务小区信号的电平强度跟MR中服务小区信号的电平强度的近似程度；2. Determine how similar the level strength of the serving cell signal corresponding to the grid is to the level strength of the serving cell signal in the MR;

判决过程可以依据以下几个原则：The judgment process can be based on the following principles:

(a)栅格的预测接收信号电平与MR中的接收信号电平越接近，则该栅格的特征与测量报告信息越接近。(a) The closer the predicted received signal level of a grid is to the received signal level in the MR, the closer the characteristic of the grid is to the measurement report information.

或(b)MR中服务小区对应的接收信号电平在绝对值匹配中的权重最大，其次是MR中服务小区的第一强邻区，其它邻区的权重依次递减。Or (b) the received signal level corresponding to the serving cell in MR has the largest weight in absolute value matching, followed by the first strong neighbor cell of the serving cell in MR, and the weights of other neighbor cells decrease in turn.

或(c)按照测量报告中小区的排列，如果栅格信息中对应找到的匹配的小区连续性越好，则与测量报告的匹配性越好。Or (c) according to the arrangement of the cells in the measurement report, if the continuity of the matching cells found in the grid information is better, the matching with the measurement report is better.

根据以上原则实现绝对值的匹配。其中原则c与原则a相比，对匹配结果的影响所起的作用更加明显，这样也较好地解决了实际无线网络环境是时变的问题。The absolute value matching is realized according to the above principles. Compared with principle a, principle c has a more obvious effect on the matching result, which also better solves the problem that the actual wireless network environment is time-varying.

3、从该栅格所对应的信息中查找是否包含MR中服务小区的第一强邻区的信息，如果包含，进入下一步骤，否则，流程结束，或者，比较MR中的下一个信息；3. From the information corresponding to the grid, find whether the information of the first strong neighbor cell of the serving cell in the MR is included, and if yes, proceed to the next step, otherwise, the process ends, or compare the next information in the MR;

4、利用上述原则判决该栅格所对应的第一强邻区信号的电平强度跟MR中第一强邻区信号的电平强度的近似程度，近似程度的判决原则与步骤2相同；4. Use the above principles to determine the degree of approximation between the level strength of the first strong neighboring cell signal corresponding to the grid and the level strength of the first strong neighboring cell signal in the MR. The principle of judging the degree of approximation is the same as step 2;

直到将MR中所有小区的信息都与该栅格所对应的信息进行了比较，再根据MR中所有小区比较的近似情况进行评估，当MR中所有小区与该栅格所对应的信息均一致时，可以用数值0表示绝对值匹配的结果，当没有一致的信息时，可以用数值1表示，当所有小区的信息中部分小区的信息一致时，可以用0至1之间的数值表示。Until the information of all the cells in the MR is compared with the information corresponding to the grid, and then evaluated according to the approximate situation of all the cells in the MR, when all the cells in the MR are consistent with the information corresponding to the grid , the value 0 can be used to represent the absolute value matching result, when there is no consistent information, it can be represented by a value 1, and when the information of some cells in all the cell information is consistent, it can be represented by a value between 0 and 1.

(2)相对值匹配(2) Relative value matching

由于工程参数、传播模型不准确等因素，使得绝对值匹配可能存在偏差。相对值匹配可以抵消绝对值匹配产生的偏差。这是因为：由于无线环境的时变特性，有时上报的MR并不能真实反映终端在网络位置中能够接收到信号的情况，比如：终端在瞬时未能接收到一个信号，但是终端在其它时刻就有可能接收到该信号。绝对值匹配无法识别出这种情况，而相对值匹配要同时使用来自两个小区的信号进行衡量，这样就可以从一定程度上避免无线环境瞬时变化带来的不准确性。Due to factors such as engineering parameters and inaccurate propagation models, there may be deviations in absolute value matching. Relative value matching can offset the bias produced by absolute value matching. This is because: due to the time-varying characteristics of the wireless environment, sometimes the reported MR cannot truly reflect the situation that the terminal can receive the signal in the network location. It is possible to receive the signal. Absolute value matching cannot identify this situation, while relative value matching needs to be measured using signals from two cells at the same time, so that inaccuracies caused by instantaneous changes in the wireless environment can be avoided to a certain extent.

本发明实施例进行相对值匹配包括：针对每个栅格，根据接收到的MR中各小区的接收信号电平，将终端服务小区的每个邻区接收信号电平除以服务小区接收信号电平得到第一组数值。将预测服务小区的每个邻区接收信号电平除以预测服务小区接收信号电平得到第二组数值。依据以下相对值匹配原则将第一组数值与第二组数值进行匹配。In the embodiment of the present invention, performing relative value matching includes: for each grid, according to the received signal level of each cell in the MR, dividing the received signal level of each adjacent cell of the serving cell of the terminal by the received signal level of the serving cell Ping to get the first set of values. Divide the received signal level of each neighboring cell of the predicted serving cell by the received signal level of the predicted serving cell to obtain the second set of values. Match the first set of values with the second set of values according to the following relative value matching principles.

相对值匹配的原则是：The principle of relative value matching is:

栅格预测的相对接收电平比与测量到的相对接收电平比越接近(即第一组数值与第二组数值越接近)，该栅格作为定位点越合理。The closer the relative receiving level ratio predicted by the grid is to the measured relative receiving level ratio (that is, the closer the first group of values is to the second group of values), the more reasonable the grid is as an anchor point.

第一组数据与第二组数据匹配完后，针对每个栅格综合所有的匹配结果设置一个数值。After the first set of data is matched with the second set of data, a value is set for each grid to integrate all the matching results.

步骤206：基站控制器综合绝对值匹配与相对值匹配确定出终端位置所在的栅格。Step 206: The base station controller determines the grid where the terminal is located based on the absolute value matching and the relative value matching.

进行了绝对值匹配与相对值匹配之后，对定位区域内的每个栅格计算一个数值，该数值表示每个栅格所代表的地理位置与终端位置的近似程度，以cost表示该数值，每个栅格的cost值为：After performing absolute value matching and relative value matching, a value is calculated for each grid in the positioning area, which indicates the degree of approximation between the geographic location represented by each grid and the terminal position, and the value is represented by cost. The cost value of a raster is:

cost_i＝α·L_i1+β·L_i2cost_i ＝α·L_i1 +β·L_i2

其中，cost_i为第i个栅格的cost值，L_i1为第i个栅格为绝对值匹配设置的值，L_i2为第i个栅格为相对值匹配设置的值，α为绝对值匹配的权重，β为相对值匹配的权重。如果预测接收电平数据库的精确度很高，即预测的数据与路测数值的近似程度大于预置门限，则α的值相对于β较大。如果预测接收电平数据库的精度不高，则β的值相对于α较大。Among them, cost_i is the cost value of the i-th grid, L_i1 is the value set for the i-th grid for absolute value matching, L_i2 is the value set for the i-th grid for relative value matching, and α is the absolute value Matching weight, β is the weight of relative value matching. If the accuracy of the predicted receiving level database is high, that is, the similarity between the predicted data and the drive test value is greater than the preset threshold, the value of α is larger than β. If the accuracy of the predicted reception level database is not high, the value of β is larger than that of α.

最后，在所有栅格的cost值中，将cost值最小的栅格所对应的地理位置确定为终端的位置。Finally, among the cost values of all the grids, the geographic location corresponding to the grid with the smallest cost value is determined as the location of the terminal.

在本发明实施例二中，绝对值匹配在无线网络环境较为稳定时具有较高的精度，因此，当无线网络环境较为稳定时，相对值匹配的权重可以设置较小的数值，绝对值匹配可以设置较大的数值，当无线网络环境不稳定时，相对值匹配的权重可以设置较大的数值，绝对值匹配可以设置较小的数值，通过相对值匹配的结果对绝对值匹配的结果进行补偿，从而，当无线网络环境不稳定时，通过本发明实施例仍然可以获得较高的确定终端位置的定位精度。In Embodiment 2 of the present invention, the absolute value matching has higher precision when the wireless network environment is relatively stable. Therefore, when the wireless network environment is relatively stable, the weight of the relative value matching can be set to a smaller value, and the absolute value matching can be Set a larger value. When the wireless network environment is unstable, the weight of relative value matching can be set to a larger value, and the weight of absolute value matching can be set to a smaller value. Compensate the result of absolute value matching through the result of relative value matching , so that when the wireless network environment is unstable, the embodiment of the present invention can still obtain high positioning accuracy for determining the position of the terminal.

可选地，还可以通过建立精度更高的接收电平数据库，或利用修正后的单位时间提前量(TA，Time Advance)的传播距离确定精度更高的定位区域来提高定位精度，或者建立精度更高的接收电平数据库的同时利用TA确定精度更高的定位区域来提高定位精度。Optionally, positioning accuracy can also be improved by establishing a receiving level database with higher accuracy, or using the corrected propagation distance per unit time advance (TA, Time Advance) to determine a location area with higher accuracy, or establishing an accuracy The higher receiving level database uses TA to determine the positioning area with higher accuracy to improve the positioning accuracy.

请参考图3，为本发明实施例三确定终端位置的方法示意图，可以包括以下步骤：Please refer to FIG. 3, which is a schematic diagram of a method for determining the location of a terminal according to Embodiment 3 of the present invention, which may include the following steps:

步骤301：工程师对定位区域进行路测；Step 301: The engineer conducts a drive test on the positioning area;

步骤302：安装了专门软件的计算机利用路测数据对传播模型进行矫正，并对单位TA的传播距离进行修正；Step 302: the computer with special software installed uses the drive test data to correct the propagation model and correct the propagation distance of the unit TA;

对传播模型进行矫正包括：将路测数据转换为连续波(CW，ContinuousWave)测试数据，利用CW测试数据对传播模型进行矫正。矫正后，对有路测数据的区域使用路测数据，没有路测数据的区域使用预测数据。Correcting the propagation model includes: converting drive test data into continuous wave (CW, Continuous Wave) test data, and correcting the propagation model by using the CW test data. After correction, the drive test data is used for the areas with drive test data, and the predicted data is used for the areas without drive test data.

MR中的TA可以辅助进行定位，即通过TA时长内的无线电波传播的距离来辅助定位。根据无线传播原理，单位TA对应的无线传播距离为：The TA in MR can assist in positioning, that is, the positioning can be assisted by the distance traveled by radio waves within the TA duration. According to the principle of wireless propagation, the wireless propagation distance corresponding to the unit TA is:

1/2*每比特时长*无线电波传播速度≈550m1/2*per bit duration*radio wave propagation speed≈550m

在实际的传播环境中，多径衰落使得一个TA时间的无线信号并不一定传播550m。如果在任何场景都对TA取值550m，势必影响定位的精度。因此，本发明实施例针对不同的场景、不同的定位区域，根据路测数据对单位TA的传播距离进行修正。In an actual propagation environment, multipath fading makes it impossible for a TA time wireless signal to propagate 550m. If the value of TA is set to 550m in any scene, it will inevitably affect the positioning accuracy. Therefore, the embodiment of the present invention corrects the propagation distance of the unit TA according to the drive test data for different scenarios and different positioning areas.

对单位TA的传播距离进行修正包括：一个MR包含一个TA，针对大量MR中的每个MR，利用MR中的TA计算出服务小区的基站到路测点的时间；计算出的时间乘以550m得到服务小区的基站到路测点的距离；对大量的TA以及分别得到的服务小区的基站到路测点的距离进行拟合，从而实现对单位TA的传播距离进行修正。The correction of the propagation distance of the unit TA includes: one MR contains one TA, and for each MR in a large number of MRs, the time from the base station of the serving cell to the road measurement point is calculated by using the TA in the MR; the calculated time is multiplied by 550m Obtain the distance from the base station of the serving cell to the road measurement point; fit a large number of TAs and the distances from the base station of the serving cell to the road measurement point respectively, so as to realize the correction of the propagation distance of the unit TA.

步骤303：该计算机根据矫正后的传播模型，利用路测数据以及预测数据建立接收电平数据库；Step 303: the computer uses the drive test data and prediction data to establish a receiving level database according to the corrected propagation model;

建立的接收电平数据库针对每个栅格，对路测数据进行离散平滑处理；然后基于以下原则进行预测：有路测数据的栅格用路测数据作为特征信息，没有路测数据的栅格通过预测出来的信息作为特征信息。The established receiving level database performs discrete smoothing processing on the drive test data for each grid; and then predicts based on the following principles: the grid with drive test data uses the drive test data as feature information, and the grid without drive test data The predicted information is used as feature information.

步骤304：基站控制器接收终端上报的MR；Step 304: the base station controller receives the MR reported by the terminal;

步骤305：基站控制器根据终端上报的MR中的TA缩小定位区域，并从该计算机获取接收电平数据库；Step 305: The base station controller narrows down the positioning area according to the TA in the MR reported by the terminal, and obtains the receiving level database from the computer;

缩小定位区域包括：基站控制器从该计算机中获取修正后的单位TA的传播距离，根据服务小区基站天线的方向性以及修正后的单位TA传播距离缩小定位区域。Narrowing down the positioning area includes: the base station controller obtains the corrected propagation distance per unit TA from the computer, and narrows down the positioning area according to the directionality of the base station antenna of the serving cell and the corrected propagation distance per unit TA.

下面以一个具体实例对缩小定位区域进行说明。The narrowing of the positioning area is described below with a specific example.

请参考图4，为本发明实施例三中的缩小定位区域示意图。在图4中，401为服务小区的基站，402至407均表示服务小区的有效邻区，408表示401的天线方向角。将MR的TA值乘以修正后的单位TA的传播距离得到第一距离，以401为原点，以第一距离为半径得到第一弧线409，将MR的TA值加上第一TA预设值得到第一TA值，将第一TA值乘以修正后的单位TA的传播距离得到第二距离，以401为原点，以第二距离为半径得到第二弧线410，将MR的TA值减去第二TA预设值得到第二TA值，将第二TA值乘以修正后的单位TA的传播距离得到第三距离，以401为原点，以第三距离为半径得到第三弧线411。第二弧线410与第三弧线411之间的区域为缩小后的定位区域。需要指出的是，第一TA预设值可以与第二TA预设值相同，也可以不同于第二TA预设值。由于第一TA预设值以及第二TA预设值的取值会影响定位区域的范围，因此，第一TA预设值和第二TA预设值的取值不仅要保证表示终端位置的定位点位于定位区域内，同时还要尽可能地缩小定位区域，以减少运算量。Please refer to FIG. 4 , which is a schematic diagram of the reduced positioning area in Embodiment 3 of the present invention. In FIG. 4 , 401 is the base station of the serving cell, 402 to 407 all represent effective neighboring cells of the serving cell, and 408 represents the antenna direction angle of 401 . Multiply the TA value of MR by the propagation distance of the corrected unit TA to obtain the first distance, take 401 as the origin, and use the first distance as the radius to obtain thefirst arc 409, add the TA value of MR to the first TA preset value to obtain the first TA value, multiply the first TA value by the corrected propagation distance of the unit TA to obtain the second distance, take 401 as the origin, and use the second distance as the radius to obtain thesecond arc 410, the TA value of MR Subtract the second TA preset value to get the second TA value, multiply the second TA value by the corrected unit TA propagation distance to get the third distance, take 401 as the origin, and use the third distance as the radius to get thethird arc 411. The area between thesecond arc 410 and thethird arc 411 is the reduced positioning area. It should be noted that the first TA preset value may be the same as the second TA preset value, or may be different from the second TA preset value. Since the values of the first TA preset value and the second TA preset value will affect the scope of the positioning area, the values of the first TA preset value and the second TA preset value must not only ensure the positioning of the terminal position The point is located in the positioning area, and the positioning area should be reduced as much as possible to reduce the amount of calculation.

例如：假设MR中的TA为2，修正后的单位TA的传播距离为500m，以401为原点，以1000m(2*500m＝1000m)为半径，可以得到一条弧线，将2减去0.5得到1.5，以401为原点，以750m(1.5*500m＝750m)为半径可以得到一条弧线，将2加上0.5得到2.5，以401为原点，以1250m(2.5*500m＝1250m)为半径可以得到一条弧线，后得到的两条弧线之间的区域为定位区域。For example: Assuming that TA in MR is 2, the propagation distance of the corrected unit TA is 500m, with 401 as the origin and 1000m as the radius (2*500m=1000m), an arc can be obtained, and 2 is subtracted from 0.5 to get 1.5, take 401 as the origin and 750m (1.5*500m=750m) as the radius to get an arc, add 2 to 0.5 to get 2.5, take 401 as the origin and 1250m (2.5*500m=1250m) as the radius to get An arc, and the area between the two arcs is the positioning area.

步骤306：基站控制器在缩小后的定位区域内，根据接收到的MR以及该计算机建立的接收电平数据库，综合绝对值匹配与相对值匹配确定出终端位置所在的栅格。Step 306: The base station controller determines the grid where the terminal is located in the narrowed positioning area based on the received MR and the receiving level database established by the computer, through absolute value matching and relative value matching.

综合绝对值匹配与相对值匹配确定终端位置的方法与本发明实施例二相同，具体请参见本发明实施例二，不再赘述。The method for determining the location of the terminal by combining absolute value matching and relative value matching is the same as that in Embodiment 2 of the present invention. Please refer to Embodiment 2 of the present invention for details, and details are not repeated here.

可以看出，通过综合绝对值匹配以及相对值匹配提高了定位精度，进一步地，接收电平数据库中的数据由来自实际环境中路测数据以及预测数据组成，路测数据的精度高于预测数据，且预测数据是通过对传播模型矫正得到的，精度高于没有对传播模型矫正得到的预测数据，因此，可以提高确定终端位置的定位精度。并且，精度更高的定位区域同样提高了确定终端位置的定位精度。It can be seen that the positioning accuracy is improved by combining absolute value matching and relative value matching. Further, the data in the receiving level database is composed of drive test data and prediction data from the actual environment, and the accuracy of drive test data is higher than that of prediction data. In addition, the prediction data is obtained by correcting the propagation model, and its accuracy is higher than that obtained without correcting the propagation model. Therefore, the positioning accuracy for determining the position of the terminal can be improved. Moreover, the positioning area with higher accuracy also improves the positioning accuracy for determining the position of the terminal.
