本申请要求于 2007 年 5 月 17 日提交中国专利局、申请号为 200710107823.4、发明名称为 "通信***网络规划的方法和设备"的中国专利申请的优先权，其全部内容通过引用结合在本申请中。技术领域 The present application claims priority to Chinese Patent Application No. 200710107823.4, entitled "Method and Apparatus for Network Planning of Communication Systems", filed on May 17, 2007, the entire contents of which is incorporated herein by reference. in. Technical field

本发明涉及通信技术领域 , 尤其涉及一种通信***网络规划的方法和设备。背景技术 The present invention relates to the field of communications technologies, and in particular, to a method and a device for network planning of a communication system. Background technique

由于 3G ( 3^rd Generation, 第三代移动通信***）的无线网络规划和优化比 2G ( 2^nd Generation, 第二代移动通信***）的网络复杂得多，因此为 3G 网络的建设寻找一种高效的规划和优化方法是倍受关注的问题。 Since the 3G (3 ^rd Generation, third generation mobile communication system) radio network planning and optimization more complex than 2G (2 ^nd Generation, a second generation mobile communication system) network, so as to find an efficient 3G network construction The planning and optimization method is a matter of great concern.

目前，在 3G无线网络规划阶段，一般首先要进行 CW( Continuous Wave, 连续波）测试，根据 CW数据进行传播模型校正，然后进行小区的覆盖预测，最后利用覆盖预测的结果得到网络规划解决方案。按照传统的方法，覆盖预测主要是通过利用传播模型并结合数字地图计算出发射机与接收机之间的无线链路损耗。目前业界存在的传播模型主要包括两种，分别为基于统计的传播模型如基于 Hata的宏蜂窝传播模型，以及确定的传播模型如射线跟踪传播模型。使用 Hata传播模型，虽然能够利用 CW测试进行模型校正，但无法模拟如城区所具有的显著阴影衰落变化；而射线跟踪传播模型虽然可以较好的模拟城区传播环境，但是对数字地图的精度要求比较高，需要有地物类型、地物高度、建筑物高度等参数，并且也需要使用 CW测试仪得到的数据来进行传播模型校正。而 CW测试不仅耗费了运营商的大量成本，而且比较耗时，影响了网络建设的周期，网络覆盖预测准确性也得不到保证，使得规划的代价和工作量都比较高。 At present, in the 3G wireless network planning stage, CW (Continuous Wave) testing is generally first performed, propagation model correction is performed according to CW data, and then coverage prediction of the cell is performed. Finally, the network planning solution is obtained by using the coverage prediction result. According to the traditional method, the coverage prediction is mainly calculated by using the propagation model combined with the digital map to calculate the wireless link loss between the transmitter and the receiver. At present, there are two main propagation models in the industry, namely, statistical-based propagation models such as Hata-based macrocell propagation models, and determined propagation models such as ray tracing propagation models. Using the Hata propagation model, although the CW test can be used for model correction, it is impossible to simulate significant shadow fading changes such as urban areas; while the ray tracing propagation model can better simulate the urban communication environment, but the accuracy requirements of digital maps are compared. High, parameters such as feature type, feature height, building height, etc. are required, and data obtained by the CW tester is also required to perform propagation model correction. The CW test not only consumes a large amount of cost from the operator, but also is time consuming, affecting the network construction cycle, and the network coverage prediction accuracy is not guaranteed, so that the planning cost and workload are relatively high.

为了解决这个问题，现有技术中提出了一种利用已有路测数据进行网络的规划优化的方法，利用已有 2G网络的路测数据进行 3G网络的规划优化，以此来提高预测的正确性，具体包括：步骤 sl0，获取现网的测量数据，具体数据包括地理经纬度，信号强度，天线信息，发射功率等。 In order to solve this problem, the prior art proposes a method for planning and optimizing the network by using the existing road test data, and using the road test data of the existing 2G network to optimize the planning of the 3G network, thereby improving the correctness of the prediction. Sexuality, including: Step s10: Obtain measurement data of the current network, and the specific data includes geographic latitude and longitude, signal strength, antenna information, and transmission power.

步骤 s20, 根据发射点功率，和接收到的信号强度，以及设备的损耗，将 2G路测数据信号转化为对应 3G网络的路测信号。 Step s20: Convert the 2G road test data signal into a road test signal corresponding to the 3G network according to the power of the transmission point, the received signal strength, and the loss of the device.

步骤 s30, 根据 3G网络路测信号，得出网络的性能参数。 Step s30, according to the 3G network road test signal, the performance parameters of the network are obtained.

通过使用该方法，对于当前的网络，如果该发射机存在 2G网络的路测信息，就可以得到对应路测点的 3G网络覆盖预测，从而进行网络的规划优化。但是该技术也存在以下缺点：对于对应路测点的 3G网络覆盖预测不准确，例如对于没有 2G网络的路测数据的区域，无法进行准确预测，而实际情况中没有路测数据的区域比重是相当大的，因此造成很多情况下无法使用该方法；另夕卜，再比如，该方法要求 3G网络与 2G网络共基站，如果当前规划的网络比与 2G共基站的小区数目有增加，增加的小区没有路测数据，将无法进行路侧数据到 3G路侧信号的准确转换，所以对于增加的小区也无法准确预测。发明内容 By using this method, for the current network, if the transmitter has the road test information of the 2G network, the 3G network coverage prediction of the corresponding road measurement point can be obtained, thereby performing network planning optimization. However, this technology also has the following disadvantages: The 3G network coverage prediction for the corresponding waypoint is inaccurate. For example, for the area without the 2G network's drive test data, accurate prediction cannot be made. In reality, the area ratio of the drive test data is It is quite large, so it is impossible to use the method in many cases. In addition, for example, the method requires a 3G network and a 2G network to share a base station. If the currently planned network has an increased number of cells than the 2G common base station, the increase is increased. If there is no road test data in the cell, the road side data cannot be accurately converted to the 3G road side signal, so the increased cell cannot be accurately predicted.

本发明的实施例一中 , 以利用 2G路测数据进行 3G传播模型校正和覆盖预测为例，一种通信***网络规划的方法如图 1所示，包括以下步骤： In the first embodiment of the present invention, the 3G propagation model correction and the coverage prediction are performed by using the 2G drive test data. A method for network planning of the communication system is shown in FIG. 1 and includes the following steps:

步骤 sl01、获取 2G网络和 3G网络数据。 Step sl01, obtain 2G network and 3G network data.

上述 2G网络和 3G网络数据即为现有无线通信***网络的路测信息，该 2G 网络和 3G网络数据包括 2G路测数据，以及 2G和 3G网络的工程参数。其中， 2G 网络中保存的路测数据需包括路测点的测试时间、经纬度、服务小区号、服务小区频点、服务小区接收信号电平、邻小区频点以及邻小区接收信号电平等。另外，工程参数包括如站点位置、扇区功率和天馈配置等。 The above 2G network and 3G network data are road test information of the existing wireless communication system network, and the 2G network and 3G network data include 2G drive test data, and engineering parameters of 2G and 3G networks. The road test data stored in the 2G network needs to include the test time, the latitude and longitude, the service cell number, the serving cell frequency, the serving cell receiving signal level, the neighboring cell frequency, and the neighboring cell receiving signal level. In addition, engineering parameters include site location, sector power, and antenna configuration.

根据 2G网络和 3G网络数据校正传播模型，具体的可以包括本实施例中的步骤 102至 104: The propagation model is corrected according to the 2G network and the 3G network data, and specifically may include steps 102 to 104 in this embodiment:

步骤 sl02、对 2G路测数据进行预处理。从 2G路测数据中筛选出与 3G站点共天馈的 2G站点的路测数据，整理筛选后的 2G路测数据为预先设定的格式。这些数据的特征是天馈的地理经纬度和天线的高度都与 3G站点相同，并且处于 Idle (空闲）状态，但频段、天线类型和方位角可以不同。预处理后的 2G路测数据所包括的信息可以如表 1所示，相应的整理筛选后的 2G路测数据为预先设定的格式可以参照表 1所示。 Step s102: Pre-processing the 2G drive test data. The road test data of the 2G site shared with the 3G site is filtered out from the 2G road test data, and the 2G road test data after the screening is sorted into a preset format. The characteristics of these data are that the geographic latitude and longitude of the antenna and the height of the antenna are the same as those of the 3G station, and are in the Idle state, but the frequency band, antenna type and azimuth can be different. The information included in the pre-processed 2G drive test data can be as shown in Table 1. The corresponding 2G drive test data after sorting and sorting is a preset format, as shown in Table 1.

步骤 sl03、将预处理后的 2G路测数据转换为 3G网络 CW形式数据。 Step sl03: Convert the preprocessed 2G drive test data into 3G network CW form data.

读取如表 1中所描述的 2G路测数据 ,将各个服务小区数据转换为对应的 3G 小区数据，增加到 3G小区对应的 CW形式文件中。 The 2G drive test data as described in Table 1 is read, and each service cell data is converted into corresponding 3G cell data, and added to the CW format file corresponding to the 3G cell.

步骤 sl04、利用得到的 CW形式数据进行传播模型校正。 Step sl04, using the obtained CW form data to perform propagation model correction.

利用 CW形式数据，可直接用于传播模型校正，或为没有路测数据的小区进行覆盖预测。 Using CW formal data, it can be used directly for propagation model correction, or for coverage prediction for cells without drive test data.

步骤 sl05、根据 2G路测数据和校正后的传播模型进行 3G网络的覆盖预测。其中， 3G网络为需要规划的通信***网络，进行 3G网络的覆盖预测即为生成 3G网络中的参数信息。下面对实施例一中的步骤 si 03做进一步说明，描述如何将 2G路测数据转换为 3G网络 CW形式数据，该转换流程如图 2所示，具体包括：步骤 s201、从 2G路测文件中取出一个当前路测点，当前的路测信息即如表 1所描述的信息。 Step s105, performing coverage prediction of the 3G network according to the 2G drive test data and the corrected propagation model. The 3G network is a communication system network that needs to be planned, and the coverage prediction of the 3G network is to generate parameter information in the 3G network. The following describes the step si 03 in the first embodiment, and describes how to convert the 2G drive test data into the CW form data of the 3G network. The conversion process is as shown in FIG. 2, and specifically includes: Step s201: Take a current road measurement point from the 2G road test file, and the current drive test information is the information described in Table 1.

步骤 s202、将当前路测点的服务小区数据转换为对应的 3G小区数据，增加到 3G小区对应的 CW形式文件中。 Step s202: Convert the serving cell data of the current waypoint to the corresponding 3G cell data, and add it to the CW format file corresponding to the 3G cell.

该步骤具体包括以下步骤： This step specifically includes the following steps:

( 1 )获得与 2G小区匹配的 3G小区。根据当前路测点的 2G服务小区号，在 2G工程参数信息中，找到该服务小区的天线参数信息、 BCCH ( Broadcast Control Channel, 广播控制信道）发射功率和天馈参数。根据 2G服务小区的地理经纬度、天线参数，以及 3G的工程参数信息，找到与 2G服务小区共站点和天馈的 3G小区。 (1) Obtain a 3G cell that matches the 2G cell. According to the 2G serving cell number of the current waypoint, in the 2G engineering parameter information, the antenna parameter information of the serving cell, the BCCH (Broadcast Control Channel) transmit power, and the antenna feed parameter are found. According to the geographic latitude and longitude of the 2G serving cell, the antenna parameters, and the engineering parameter information of the 3G, the 3G cell shared with the 2G serving cell and the antenna is found.

( 2 )在该 3G小区的 CW形式测量数据文件中增加一个测量点。测量点的信息包括测试时间、路测点 GPS ( Global Positioning System, 全球定位***）经纬度，以及 3G小区接收信号电平。其中测试时间、路测点 GPS经纬度与 2G 服务小区的路测点数据相同， 3G小区的接收信号电平根据 2G服务小区的接收信号电平得到，计算公式如下： (2) Add a measurement point to the CW form measurement data file of the 3G cell. The measurement point information includes test time, GPS (Global Positioning System) latitude and longitude, and 3G cell received signal level. The test time and the road measurement point GPS latitude and longitude are the same as the road measurement point data of the 2G serving cell, and the received signal level of the 3G cell is obtained according to the received signal level of the 2G serving cell, and the calculation formula is as follows:

3G小区的接收信号电平 =路测点服务小区 BCCH接受信号电平 Receive signal level of 3G cell = waypoint service cell BCCH accept signal level

+ ( 3G小区的发射功率 - 2G服务小区 BCC 射功率） + ( transmit power of 3G cell - 2G serving cell BCC radio power)

+ ( 3G天线接收点的天线增益 - 2G天线接收点的天线增益） + ( Antenna gain at the receiving point of the 3G antenna - Antenna gain at the receiving point of the 2G antenna)

+ ( 2G天线馈线损耗 - 3G天线馈线损耗） + ( 2G antenna feeder loss - 3G antenna feeder loss)

+ 2G网络与 3G网络之间的频差引起的链路损耗差 + poor link loss due to frequency difference between 2G network and 3G network

上述公式中，天线增益是根据网络的天线类型、天线角度、天线的波瓣图，以及天线和接收点的地理位置计算获得。 2G网络与 3G网络之间的频差引起的链路损耗差可以来自与经验值，也可以根据一些已知的传播模型推导。因此 3G 网络可以与 2G网络的频段不同，天线的类型和角度等也可以调整，最大范围的利用了已有的路测数据。 In the above formula, the antenna gain is calculated based on the antenna type of the network, the antenna angle, the lobe pattern of the antenna, and the geographical position of the antenna and the receiving point. The link loss caused by the frequency difference between the 2G network and the 3G network can come from empirical values or can be derived from some known propagation models. Therefore, the 3G network can be different from the frequency band of the 2G network, and the type and angle of the antenna can also be adjusted. The maximum range utilizes the existing drive test data.

步骤 s203、将邻小区 Ni数据转换为对应的 3G小区数据，增加到 3G小区对应的 CW形式文件中。 Step s203: Convert the neighboring cell Ni data into the corresponding 3G cell data, and add the data to the CW format file corresponding to the 3G cell.

该步骤的操作与上一步骤 s202的操作基本相同，区别在于 2G网络路测点的服务小区号在解调服务小区 BCCH信道时已经获得，路测点信息中已经给出了小区号，但是所有邻小区的小区号却无法在测试时获取，需要通过 2G网络小区号与频点、 BSIC ( Base transceiver Station Identity Code, 基站识别码）的对应关系，以及地理位置匹配映射得到。得到邻小区的小区号后，后续操作则同步骤 s202。 The operation of this step is basically the same as the operation of the previous step s202. The difference is that the serving cell number of the 2G network path measurement point has been obtained when demodulating the BCCH channel of the serving cell, and the road measurement point information has been given. The cell number, but the cell number of all the neighboring cells cannot be obtained during the test, and needs to be obtained through the correspondence between the cell number of the 2G network and the frequency point, the BSIC (Base Transmitter Identity Code), and the geographical location matching mapping. After the cell number of the neighboring cell is obtained, the subsequent operation is the same as step s202.

步骤 s204、判断所有邻小区是否已经处理完毕，未完毕时进行步骤 s203 , 已经处理完毕则进行步骤 s205。 In step s204, it is determined whether all neighboring cells have been processed. If not, step s203 is performed, and if it has been processed, step s205 is performed.

步骤 s205、 2G路测文件下移一个路测点。 Step s205, 2G way test file moves down one way measurement point.

步骤 s206、判断 2G路测文件是否处理结束，若未结束则进行步骤 s201 , 若已经结束则整个流程完成。 Step s206: Determine whether the 2G drive test file is processed. If not, proceed to step s201. If it has ended, the entire process is completed.

通过以上步骤 S201至 S206, 实现获取路测点中所有 2G小区的小区号；才艮据小区号获取 2G小区的数据信息；根据 2G小区的数据信息获取与 2G小区共站点和天馈的 3G小区；根据 2G小区的数据信息获取 3G小区的数据信息；将 3G小区的数据信息增加到 3G小区对应的连续波形式数据。下面对实施例一中的步骤 sl04做进一步说明，描述如何利用得到的 CW形式数据进行传播模型校正。利用 CW形式数据，可直接用于传播模型校正，或为没有路测数据的小区进行覆盖预测。 Obtaining, by using the foregoing steps S201 to S206, obtaining the cell number of all the 2G cells in the waypoint; obtaining the data information of the 2G cell according to the cell number; acquiring the 3G cell shared by the 2G cell and the antenna of the antenna according to the data information of the 2G cell Obtaining data information of the 3G cell according to the data information of the 2G cell; and increasing the data information of the 3G cell to the continuous wave form data corresponding to the 3G cell. Next, the step sl04 in the first embodiment will be further described, and how to perform propagation model correction using the obtained CW-shaped data will be described. Using CW formal data, it can be used directly for propagation model correction, or for coverage prediction for cells without drive test data.

可以采用基于标准 Hata模型基础上改进的传播模型，例如 SPM ( Standard Propagation Model, 标准传播模型）。一般在网络规划过程中，都需要对这些统计的传播模型进行校正，然后才能进行覆盖预测。本文就以 SPM为例来说明如何利用在第三步中得到的 CW形式数据进行传播模型校正。如图 3所示，为模型校正的流程图。 An improved propagation model based on the standard Hata model, such as the SPM (Standard Propagation Model), can be used. Generally, in the network planning process, the propagation models of these statistics need to be corrected before coverage prediction can be performed. This article uses SPM as an example to illustrate how to use the CW form data obtained in the third step for propagation model correction. As shown in Figure 3, it is a flow chart for model correction.

步骤 s301、获取已转化为 CW形式数据的路测数据。 Step s301: Acquire a drive test data that has been converted into CW form data.

将所有的 2G路测信息处理完毕后，处理后就会得到各 3G小区的 CW形式测试数据文件，为了提高数据准确性，需要对这些 CW形式数据进行处理，处理包括数据的过滤，以及数据离散和数据地理平均。 After all the 2G road test information is processed, the CW form test data file of each 3G cell is obtained after processing. In order to improve the data accuracy, these CW form data needs to be processed, including data filtering, and data discretization. And geographic geographic average.

步骤 s302、筛选过滤该 CW形式的数据。 Step s302: Filter and filter the data in the CW format.

在实际路测过程中，难以避免地会出现一些误差较大的数据，为了避免这些数据带来误差，需要将这部分数据加以筛选过滤，过滤主要有基于测量值的过滤和基于距离的过滤。 In the actual road test process, it is difficult to avoid some data with large error. In order to avoid the error caused by these data, this part of the data needs to be filtered and filtered. The filtering is mainly based on the measured value. Filtering and distance-based filtering.

基于测量值的过滤：测量值较低的时候,接收机处于解出信号的临界状态，其测量值容易受到瞬时波动的影响，再结合设备的性能，在测试过程中场强大于某个门 P艮或者小于某个门限的数据需要滤除。 Filtering based on measured values: When the measured value is low, the receiver is in the critical state of the solved signal, and its measured value is easily affected by the instantaneous fluctuation. Combined with the performance of the device, the field is stronger than a certain gate during the test.艮 or data below a certain threshold needs to be filtered out.

基于距离的过滤：在测试数据中，当距离太远时，由于信号太弱而容易出现野值点（测量数据集合中严重偏离大部分数据所呈现趋势的小部分数据点），此时接收机处于解出信号的临界状态，其测量值容易受到瞬时波动的影响。而距离太近时较容易形成直达径，直达径与非直达径的信号强度有较大的差值，容易出现较大的测量误差，使测试数据偏离。因此在本次的测试数据中，距离基站过近的点（小于一定距离）和过远的点（大于一定距离）都相对有更大的机会成为野值点，误差较大，因此这部分数据也加以滤除。 Distance-based filtering: In the test data, when the distance is too far, the wild value point is easy to occur because the signal is too weak (a small part of the data point in the measurement data set that seriously deviates from the trend of most data), then the receiver In the critical state of the signal to be solved, the measured value is susceptible to transient fluctuations. When the distance is too close, the direct path is easy to form, and the signal strength between the direct path and the non-direct path has a large difference, which is prone to large measurement errors and deviate the test data. Therefore, in this test data, the points that are too close to the base station (less than a certain distance) and the points that are too far away (more than a certain distance) have a greater chance of becoming a wild value point, and the error is larger, so this part of the data Also filtered out.

步骤 s303、对 CW数据进行离散和地理平均。 Step s303, performing discrete and geographic averaging on the CW data.

利用随机过程的理论分析移动通信的传播，可表示为： Using the theory of stochastic processes to analyze the propagation of mobile communications can be expressed as:

r(x) = m(x)r₀ (x) r(x) = m(x)r ₀ (x)

其中， X为距离， r(x)为接收信号； r₀(x)为瑞利衰落； m(x)为本地均值，也就是长期衰落和空间传播损耗的合成，可以表示为：

Where X is the distance, r(x) is the received signal; r ₀ (x) is the Rayleigh fading; m(x) is the local mean, which is the synthesis of long-term fading and spatial propagation loss, which can be expressed as:

其中 2L为平均采样区间长度，也叫本征长度。 2L is the average sampling interval length, also called the intrinsic length.

CW测试就是尽可能获取在某一地区各点地理位置的本地均值 , 即 r(x)与 m(x)之差尽可能小，因此要获得本地均值必须去除瑞利衰落的影响。对于一组测量数据做平均时，若本征长度太短，则仍有瑞利衰落的影响存在；若 2L太长，则会把正态衰落也平均掉。根据李氏定理，在本征长度为 40个波长，采样 50 个样点时，可使测试数据与实际本地均值之差小于 ldB。 The CW test is to obtain the local mean of the geographical position of each point in a certain area as much as possible, that is, the difference between r(x) and m(x) is as small as possible, so to obtain the local mean, the influence of Rayleigh fading must be removed. When averaging a set of measured data, if the eigen length is too short, there is still the effect of Rayleigh fading; if 2L is too long, the normal fading is also averaged. According to Lee's theorem, when the intrinsic length is 40 wavelengths and 50 samples are sampled, the difference between the test data and the actual local mean can be made smaller than ldB.

由上可见，本征长度就是进行地理平均的长度。例如在 2G频段，发射波长为 0.15米， 40个波长就是 6米，也就是说需要每 6米做一次平均，但是所测得的数据由于 GPS定位速度太慢，一秒只能定位一个点，如果车速为 50km/h, 即每 14米才能定位一个点，显然不能直接做地理平均，因此在地理平均之前需要做离散处理。在所获得的 CW测试数据中 , 由于接收机的接收速度远大于 GPS的定位速度，因而在每个定位点（相同的经纬度 )下按时间顺序排列着很多条测量记录。假定每两个定位点之间车速是均匀的 ,且每两条测量记录之间的时间间隔相等 (在误差允许范围内这都是可以满足的） , 则可以将这些测量记录按时间顺序均匀分布到两点之间的路段，这样就可以满足在测试路线上每个 6米长度内都有足够的点数。 It can be seen from the above that the intrinsic length is the length of the geographical average. For example, in the 2G frequency band, the emission wavelength is 0.15 meters, and the 40 wavelengths are 6 meters, which means that it needs to be averaged every 6 meters, but the measured data is too slow to locate a point because of the GPS positioning speed is too slow. If the speed is 50km/h, that is, every 14 meters can locate a point, obviously it is not possible to directly make a geographical average, so it needs to be discrete before the geographic average. In the obtained CW test data, since the receiving speed of the receiver is much larger than the positioning speed of the GPS, a plurality of measurement records are arranged in chronological order at each positioning point (same latitude and longitude). Assuming that the vehicle speed is uniform between every two positioning points and the time interval between every two measurement records is equal (this can be satisfied within the error tolerance), these measurement records can be evenly distributed in chronological order. By the way between the two points, it is sufficient to have enough points for each 6m length on the test route.

做完数据离散后就可以进行地理平均，地理平均的目的就是消除快衰落，保留慢衰落的影响，其做平均的范围就是本征长度。做地理平均有两种方法，分别为：距离平均方式和栅格平均方式。距离平均方式是指以一段路测距离 (m)为平均单位取测量值，最后测试点定位在"线段"一端。栅格平均方式是指按经纬度将地表划分为许多小栅格，栅格边长（s) 可以设置，将落在某一网格内的所有测量点作为平均对象，取得数据后，再将栅格中心位置作为最后测试点（地理平均后）的位置。 After the data is discretized, the geographic average can be performed. The purpose of geographic averaging is to eliminate the fast fading and preserve the effect of slow fading. The average range is the eigen length. There are two ways to do geographic averaging: distance averaging and grid averaging. The distance averaging method refers to taking the measured value by the distance measured by a distance (m), and the last test point is positioned at the end of the "line segment". The grid averaging method divides the surface into many small grids according to latitude and longitude. The grid side length (s) can be set. All the measurement points falling within a certain grid are used as the average object. After the data is obtained, the grid is obtained. The position of the grid center is the position of the last test point (after the geographic average).

步骤 s304、设置 SPM传播模型的初始参数。 Step s304: Set initial parameters of the SPM propagation model.

SPM模型使用的公式和参数如下： The formulas and parameters used by the SPM model are as follows:

Lmodei = K_X+K₂ \og(d) + K₃ log(H_ae ) + K₄ ^Diffraction loss + K₅ log(i)xlog(H_ae ) + ^{H^+K^ (clutter) 其中， Lmodei = K _X + K ₂ \og(d) + K ₃ log(H _ae ) + K ₄ ^Diffraction loss + K ₅ log(i)xlog(H _ae ) + ^{H^+K^ (clutter) where ,

步骤 s305、利用规划工具进行传播模型参数的调整。 Step s305: Use a planning tool to adjust the parameters of the propagation model.

在模型校正中，利用 CW测试数据对系数到、 ^以及地物平均损耗 /(c/wtter)等进行参数的校正，使模型更适合所测试的环境，一般模型校正的标准差小于 8dB是可接受的。上述模型的参数到 ^由具体的传播环境决定，是由不同地物决定的修正系数。不同的地物决定了不同的 ^,，而 K参数是通过 CW测试的数据逐步拟合出来的。 In the model correction, the CW test data is used to correct the coefficients to, ^ and the average loss/(c/wtter), so that the model is more suitable for the tested environment. The standard deviation of the general model correction is less than 8 dB. Accepted. The parameters of the above model are determined by the specific propagation environment and are the correction coefficients determined by different features. Different features determine different ^, and K parameters are gradually fitted through the CW test data.

步骤 s306、判断模型参数及标准差是否合理，若合理则继续，否则进行步骤 s305。 Step s306: Determine whether the model parameter and the standard deviation are reasonable, and if so, continue, otherwise proceed to step s305.

步骤 s307、输出校正的传播模型。 Step s307: Output a corrected propagation model.

利用拟合得到的参数以及传播模型，可以给没有路测数据的小区进行覆盖预测，也可将该模型用于后续的网络规划优化中。下面对实施例一中的步骤 sl05做进一步说明，描述如何根据 2G路测数据和校正后的传播模型进行 3G网络的覆盖预测。在上述步骤 sl05中进行 3G网络的覆盖预测，具体又分两种情况，一种情况是本小区是新增小区，在 2G网络中找不到对应的小区，因此没有对应的路测信息。另一种情况本小区有对应的 2G 小区，因此有对应的路测信息。 Using the parameters obtained by fitting and the propagation model, coverage prediction can be performed for cells without road test data, and the model can also be used for subsequent network planning optimization. The following describes step sl05 in the first embodiment to describe how to perform coverage prediction of the 3G network based on the 2G drive test data and the corrected propagation model. In the above step sl05, the coverage prediction of the 3G network is performed, and the situation is divided into two cases. In one case, the cell is a new cell, and the corresponding cell cannot be found in the 2G network, so there is no corresponding road test information. In another case, the cell has a corresponding 2G cell, so there is corresponding road test information.

对于第一种情况，本小区没有对应的 2G小区的新增 3G小区，可直接利用步骤 si 04中校正后的传播模型进行覆盖预测。 For the first case, the cell does not have a new 3G cell corresponding to the 2G cell, and the corrected propagation model in step si 04 can be directly used for coverage prediction.

对于第二种情况，在 2G网络中有对应小区的 3G小区，在预测生成该小区的参数时，又分为两种情况，一种情况是待预测点有对应的路测点，另外一种情况是待预测点没有对应路测点的空白点。根据当前小区的 CW数据文件，对于有对应路测点的点，根据当前的路测点的接收电平，以及发射端的有效率发射功率，就可以计算出发射端到接收端的路径损耗。对于没有对应路测点的空白点，如果该小区附近没有路测点，那么为保证准确性，需要借助前述步骤中校正好的传播模型进行预测，如果待预测点的附近有路测点，则可以采用拟合的方法根据周围的路测点计算出该空白点的链员耗。具体的拟合方法多种多样，一般需要借助传播模型，在传播模型的使用上可以用一般的传播模型如For the second case, there is a 3G cell corresponding to the cell in the 2G network. When predicting the parameters of the cell, it is divided into two cases. One case is that the predicted point has a corresponding waypoint, and the other The situation is that there is no blank point corresponding to the waypoint to be predicted. According to the CW data file of the current cell, for the point with the corresponding waypoint, according to the current receiving level of the waypoint and the effective transmit power of the transmitting end, the path loss from the transmitting end to the receiving end can be calculated. For a blank point that does not have a corresponding waypoint, if there is no waypoint in the vicinity of the cell, then to ensure accuracy, it needs to be predicted by the corrected propagation model in the previous step. If there is a waypoint near the predicted point, The fitting cost is used to calculate the chain member's consumption of the blank point based on the surrounding road measurement points. A variety of specific fitting methods In general, it is necessary to use the propagation model. In the use of the propagation model, a general propagation model can be used.

Hata模型，也可以使用本发明实施例中提供的校正后的传播模型，以得到更加准确的预测结果。在确定传播模型后，具体的计算方法如下： For the Hata model, the corrected propagation model provided in the embodiment of the present invention can also be used to obtain a more accurate prediction result. After determining the propagation model, the specific calculation method is as follows:

如图 4所示，以某个空白点 P为例，将此空白点为中心，向四周扩展一定范围，这里取 50米，形成一个正方形。这里描述的是正方形区域内存在 CW路测数据，同时这些点属于同一发射机（图中 Y所示）的情况。根据校正后的传播模型进行的拟合方法分三步： As shown in Fig. 4, taking a blank point P as an example, the blank point is centered, and a certain range is extended to the periphery, where 50 meters is formed to form a square. Described here is the case where CW drive data is present in a square area, and these points belong to the same transmitter (shown as Y in the figure). The fitting method based on the corrected propagation model is divided into three steps:

第一步：利用校正的传播模型，计算发射机到 P点（空白点）的路径损耗第二步：利用校正的传播模型，针对正方形范围内的每个路测点计算出根据传播模型得到的路径损耗与根据测量值得到路径损耗两者的误差 Δ^, 计算公式如下： Step 1: Calculate the path loss of the transmitter to point P (blank point) using the corrected propagation model. Step 2: Calculate the path based on the propagation model for each way point in the square using the corrected propagation model. The error Δ^ between the loss and the path loss based on the measured value is calculated as follows:

pk = Peir_P - i ； Apli =pli - pU Pk = Peir _P - i ; Apli =pli - pU

其中是根据传播模型计算的发射机到各路测点的路径损耗值， ^是路测点的电平值， J¾P是 CW发射机的有效发射功率， '是根据测量信号计算出来的实际路径损耗。 Among them is the path loss value of the transmitter to each measurement point calculated according to the propagation model, ^ is the level value of the road measurement point, J3⁄4P is the effective transmission power of the CW transmitter, 'is the actual path loss calculated from the measurement signal .

第三步：最后计算得出 P点的路径损耗值; ： Step 3: Finally calculate the path loss value of point P;

pl_p =plp+ (∑Apli ) In, 其中， i = l , 2 , 3. ..n, n为选定正方形区域内的路测点数目。 Pl _p =plp+ (∑Apli ) In, where i = l , 2 , 3. ..n, n is the number of waypoints in the selected square region.

除了上述拟合方法外，对于对精度要求不是非常高的，也可以利用平均插值方法，也就是直接取空白点路径损耗等于周围路测点的路径损耗的平均。 In addition to the above-mentioned fitting method, for the accuracy requirement is not very high, the average interpolation method can also be utilized, that is, the direct path loss of the blank point is equal to the average of the path loss of the surrounding road measurement points.
