Among them, the so-called static simulation means: performing multiple captures on the scene of the mobile communication system, and establishing an ideal system balance point according to each capture result, and then counting the performance of the system when achieving the ideal balance, and simulating the average performance index of the system; The so-called dynamic simulation is a discrete event simulation method, which simulates a certain cellular network topology structure, the user terminal moves according to a certain model, power on, power off, cell search, cell update, service arrival, service data generation and Transmission, information interaction, small-area handover, measurement and upper-end, communication end, etc., including the behavior of other network elements (eg, base station data reception and transmission, antenna shaping, measurement, 艮, wireless resource management) And other processes) and the process of information and signaling interaction between the various units in the network.

本实施例中， 所谓的基于 FullBuffer业务实盾上不是实际网络中真实的业务， 可以认 为是 "灌包，， 处理， 其主要目的是在测试或者验证某种方案时， 保证业务源持续有数据发 送， 避免釆用真实业务时出现断流等影响测试性能， 下同， 将不再赘述。  In this embodiment, the so-called FullBuffer service is not a real service in the actual network, and can be considered as "filling, processing, and its main purpose is to ensure that the service source continues to have data when testing or verifying a certain solution.

步骤 110: 仿真评估装置基于不同类的静态指标值确定第一维度和第二维度， 并按照 设定步长值， 分别根据第一维度和第二维度进行 grid (栅格）切片， 形成多个栅格。  Step 110: The simulation evaluation device determines the first dimension and the second dimension based on different types of static indicator values, and performs grid (grid) slices according to the first dimension and the second dimension according to the set step value, and forms multiple Grid.
例如， 本实施例中， 各 UE的静态指标值分为 C/I和 I0/N0两类， 从而将 C/I作为第一 维度， 而将 I0/N0作为第二维度， 换言之， 也可以看作是将 C/I作为 X轴， 而将 I0/N0作为 y轴。 那么， 在执行步骤 110时， 具体包括：  For example, in this embodiment, the static index values of each UE are classified into C/I and I0/N0, so that C/I is taken as the first dimension and I0/N0 is taken as the second dimension. In other words, it can also be seen. This is done by taking C/I as the X axis and I0/N0 as the y axis. Then, when performing step 110, the specific includes:

其次， 仿真评估装置釆用第二维度 I0/N0 , 按照设定步长对上述多个 C/I grid区间进行 grid切片， 形成多个栅格。  Next, the simulation evaluation device uses the second dimension I0/N0 to perform grid slicing on the plurality of C/I grid intervals according to the set step size to form a plurality of grids.
步骤 120: 仿真评估装置分别将每一类动态指标值作为第三维度， 在各栅格内分别确 定每一类动态指标值对应的釆样点， 以及根据各栅格内每一类动态指标值对应的釆样点取 值， 确定相应动态指标值与第一维度对应的静态指标值及第二维度对应的静态指标值之间 的对应关系。  Step 120: The simulation evaluation device separately uses each type of dynamic indicator value as a third dimension, and respectively determines each sample point corresponding to the dynamic indicator value in each grid, and according to each type of dynamic indicator value in each grid. The corresponding value of the sample point is determined, and the correspondence between the corresponding dynamic indicator value and the static index value corresponding to the first dimension and the static index value corresponding to the second dimension is determined.
例如， 本实施例中， 各 UE的动态指标值分为调度的 TBS信息、 S R信息和调度次数 信息， 则在执行步骤 120时， 具体包括： 首先， 仿真评估装置将 TBS信息作为第三维度， 在各栅格内分别确定 TBS信息对应 的釆样点， 即仿真得到的各 UE的 TBS信息， 以及根据每一个栅格内的 TBS信息釆样点 平均取值，确定 TBS信息与 C/I及 I0/N0之间的三维对应关系，即而拟合出一个" TBS vs C/IFor example, in this embodiment, when the dynamic index value of each UE is divided into the scheduled TBS information, the SR information, and the scheduling times information, when the step 120 is performed, the method specifically includes: First, the simulation evaluation device uses the TBS information as the third dimension, and determines the sample points corresponding to the TBS information in each grid, that is, the TBS information of each UE obtained by the simulation, and the TBS information according to each grid. The average value of the points determines the three-dimensional correspondence between the TBS information and C/I and I0/N0, that is, fits a "TBS vs C/I

C/I & I0/N0" 的三维关系平面。 The three-dimensional relational plane of C/I & I0/N0".
最后， 仿真评估装置根据调度次数信息确定调度频率 β (单位： 次 /用户 /秒）， 并将调 度频率 β作为第三维度， 在各栅格内分别确定调度频率 β对应的釆样点， 即仿真得到的各 Finally, the simulation evaluation device determines the scheduling frequency β (unit: times/user/second) according to the scheduling number information, and uses the scheduling frequency β as the third dimension, and determines the sampling points corresponding to the scheduling frequency β in each grid, that is, Simulated each
UE的调度次数信息分别对应的调度频率 β,以及根据每一个栅格内的调度频率釆样点平均 取值， 确定调度频率 β与 C/I及 I0/N0之间的三维对应关系， 即而拟合出一个 "β vs C/I &The scheduling frequency of the UE is respectively corresponding to the scheduling frequency β, and according to the scheduling frequency in each grid, the average value of the sampling point is determined, and the three-dimensional correspondence between the scheduling frequency β and C/I and I0/N0 is determined, that is, Fitting a "β vs C/I &
I0/N0" 的三维关系平面。 其中， 调度频率 β釆用如下的计算方式： = ^im^ (单位： 次 /用户 /秒） The three-dimensional relation plane of I0/N0". The scheduling frequency β釆 is calculated as follows: = ^ im ^ (unit: times/user/second)
仿真时长 * UE个数  Simulation duration * number of UEs
当然， 为进一步提高动静接口的提取精度， 也可以按照设定次数釆用步骤 100 -步骤 Of course, in order to further improve the extraction accuracy of the dynamic and static interface, step 100 can also be used according to the set number of times.
120进行多次动态预仿真， 并对多次动态预仿真后获得的同一类三维关系平面上的釆样点 进行平均处理（例如， 线性平均处理）， 从而获得相应的 "TBS vs C/I & I0/N0" 三维关系 平面、 "SNR vs C/I & I0/N0" 三维关系平面和 "β vs C/I & I0/N0" 三维关系平面。 按照上述方法确定的 "TBS vs C/I & I0/N0" 三维关系平面、 "SNR vs C/I & I0/N0" 三 维关系平面和 "β vs C/I & I0/N0" 三维关系平面即是静态指标值和动态指标值之间的对应 关系， 也称为动静接口， 或， 半静态接口。 120 performs multiple dynamic pre-simulation, and averages the sample points on the same type of three-dimensional relation plane obtained after multiple dynamic pre-simulation (for example, linear average processing), thereby obtaining the corresponding "TBS vs C/I & I0/N0" 3D relational plane, "SNR vs C/I & I0/N0" 3D relational plane and "β vs C/I & I0/N0" 3D relational plane. The "TBS vs C/I & I0/N0" three-dimensional relational plane, the "SNR vs C/I & I0/N0" three-dimensional relational plane and the "β vs C/I & I0/N0" three-dimensional relational plane determined by the above method are It is the correspondence between the static indicator value and the dynamic indicator value, also called the dynamic and static interface, or the semi-static interface.

当然， 实际应用中， 静态指标值和动态指标值也可以分别包含其他参数， 例如， 路损 测量参数、 信道衰减参数、 天线增益等等， 仿真评估装置根据实际应用场景， 也可以选择 其他类的静态指标值和动态指标值来分别建立第一维度、 第二维度和第三维度， 以确定相 应的三维关系平面， 上述 C/I、 I0/N0、 TBS信息、 SNR信息和调度次数信息仅为一种举例， 并不局限于此。  Of course, in practical applications, the static indicator value and the dynamic indicator value may also include other parameters, for example, path loss measurement parameters, channel attenuation parameters, antenna gain, etc., and the simulation evaluation device may also select other types according to actual application scenarios. The static index value and the dynamic index value respectively establish a first dimension, a second dimension, and a third dimension to determine a corresponding three-dimensional relationship plane, and the C/I, I0/N0, TBS information, SNR information, and scheduling number information are only An example is not limited to this.
基于上述实施例， 下面将介绍动静接口在半静态仿真评估中的应用， 参阅图 3所示， 本发明实施例中， 仿真评估装置基于动态预仿真的结果进行半静态仿真评估的详细流程如 下： Based on the above embodiments, the application of the dynamic and static interface in the semi-static simulation evaluation will be described below. Referring to FIG. 3, in the embodiment of the present invention, the simulation evaluation device performs a semi-static simulation evaluation based on the results of the dynamic pre-simulation. Next:
步骤 300: 仿真评估装置基于 FullBuffer业务， 针对设定的应用场景进行静态仿真， 获 得相应的静态指标值。  Step 300: The simulation evaluation device performs static simulation on the set application scenario based on the FullBuffer service, and obtains a corresponding static indicator value.
具体为： 在步骤 300时， 半静态仿真评估装置首先要进行初始 UE接入过程（接入的 UE数小于***配置的最大 UE数）， 接着， 半静态仿真评估装置完成 UE的接纳控制过程， 确定各 UE的归属地（包括归属基站、 归属扇区等等）， 然后， 半静态仿真评估装置计算各 UE的路径损耗、 阴影衰落及天线增益等信息， 从而计算出各 UE的 C/I和 I0/N0。  Specifically, in step 300, the semi-static simulation evaluation apparatus first performs an initial UE access procedure (the number of accessed UEs is smaller than the maximum number of UEs configured by the system), and then, the semi-static simulation evaluation apparatus completes the admission control process of the UE, Determining the home location of each UE (including the home base station, the home sector, and the like), and then the semi-static simulation evaluation device calculates information such as path loss, shadow fading, and antenna gain of each UE, thereby calculating the C/I of each UE. I0/N0.
步骤 310:仿真评估装置根据预先基于 FullBuffer业务，针对设定的应用场景进行动态 预仿真时确定的动态指标值和静态指标值之间的对应关系， 获得与所述静态指标值对应的 动态指标值。  Step 310: The simulation evaluation device obtains a dynamic index value corresponding to the static index value according to a correspondence between a dynamic index value and a static index value determined during dynamic pre-simulation for the set application scenario based on the FullBuffer service in advance. .
具体为：仿真装置根据在步骤 300中计算出的各 UE的 C/I和 I0/N0,在动静接口" TBS vs C/I & I0/N0"的三维关系平面上， 通过插值获得各 UE的 TBS信息， 记为 ¾&eid , 单位： kbit; Specifically, the emulation device obtains each UE by interpolation according to the C/I and I0/N0 of each UE calculated in step 300 on the three-dimensional relation plane of the dynamic and static interface "TBS vs C/I &I0/N0" TBS information, recorded as 3⁄4& eid , unit: kbit;
仿真装置根据在步骤 300中计算出的各 UE的 C/I和 I0/N0,在动静接口 "S R vs C/I & I0/N0" 的三维关系平面上， 通过插值获得各 UE的平均 SNR信息， 记为 ^ueid； The simulation device obtains the average SNR information of each UE by interpolation on the three-dimensional relational plane of the static and dynamic interface "SR vs C/I &I0/N0" according to the C/I and I0/N0 of each UE calculated in step 300. , recorded as ^ ueid ;
仿真装置根据在步骤 300中计算出的各 UE的 C/I和 I0/N0, 在动静接口 "β vs C/I & I0/N0" 的三维关系平面上， 通过插值获得各用户的调度频率记为 Aeid , 单位： 次 /用户 /秒。 The simulation device obtains the scheduling frequency of each user by interpolation on the three-dimensional relational plane of the static and dynamic interface "β vs C/I &I0/N0" according to the C/I and I0/N0 of each UE calculated in step 300. For A eid , unit: times / user / second.
步骤 320: 仿真评估装置根据获得的动态指标值， 进行***性能评估。  Step 320: The simulation evaluation device performs system performance evaluation according to the obtained dynamic index value.
本实施例中， 所谓的进行***性能评估， 即是指根据获得的动态指标值， 分别针对每 一个 UE确定以下几种参数， OTA(吞吐量）参数和 Service参数（以下筒称 OTA和 Service ), 以及 SNR信息； 然后， 再根据各 UE的 OTA和 SNR信息， 计算每个小区 （各小区已预先 仿真规划完毕） 的 OTA与 SNR, 即可获得各小区的小区吞吐量和小区信噪比， 从而完成 ***性能评估； 其中， OTA和 Service分别从不同角度表征小区或用户的吞吐量， OTA定 义为小区内正确接收的用户信息比特数与有效传输时间的比值（有效传输时间即是传输用 户信息比特所用的时间， 包括初传和重传时间）； 而 Service定义为平均每小区或每扇区单 位时间内正确传输的数据量。  In this embodiment, the so-called system performance evaluation refers to determining the following parameters, OTA (throughput) parameters and Service parameters (hereinafter referred to as OTA and Service) for each UE according to the obtained dynamic index values. And the SNR information; then, according to the OTA and SNR information of each UE, calculate the OTA and SNR of each cell (each cell has been pre-simulated and planned), and then obtain the cell throughput and the cell signal to noise ratio of each cell. The system performance evaluation is completed. The OTA and the Service respectively represent the throughput of the cell or the user from different angles. The OTA is defined as the ratio of the number of correctly received user information bits in the cell to the effective transmission time (the effective transmission time is the transmission user information). The time taken by the bit, including the initial transmission and retransmission time); and Service is defined as the amount of data that is correctly transmitted per unit or sector per unit time.
对于 Fullbuffer业务而言， 由于业务源数据充足， 因而在***参数配置相同的情况下， OTA参数和 Service参数这两个性能指标的值是相同的， 而在***参数配置不相同的情况 下， 还需要根据比例因子折算 OTA参数和等效的 Service参数的值。 本发明实施例中， 在 步骤 310中获得的动静接口为不同 UE数下的通用接口， 因此， 在动态预仿真和静态仿真 分别使用不同 UE数的情况下， 仿真评估装置均可以通过拟合的方式获得各 UE的 OTA参 数和 Service参数。  For the Fullbuffer service, since the service source data is sufficient, the values of the two performance indicators of the OTA parameter and the Service parameter are the same when the system parameter configuration is the same, and in the case where the system parameter configuration is different, The value of the OTA parameter and the equivalent Service parameter need to be converted according to the scale factor. In the embodiment of the present invention, the dynamic and static interfaces obtained in step 310 are common interfaces under different UE numbers. Therefore, in the case where dynamic pre-simulation and static simulation respectively use different UE numbers, the simulation evaluation device can all be fitted. The method obtains OTA parameters and Service parameters of each UE.
具体为： 在执行步骤 320时， 仿真评估装置首先要判断静态仿真时釆用的***配置参 数和动态预仿真时釆用的***配置参数是否一致， 即判断静态仿真时针对的应用场景和动 态预仿真时针对的应用场景是否一致， 如， 判断接入的 UE数是否一致； Specifically, when performing step 320, the simulation evaluation device first determines the system configuration parameters used in the static simulation. Whether the number of the system configuration parameters used in the dynamic pre-simulation is the same, that is, whether the application scenario for the static simulation is consistent with the application scenario for the dynamic pre-simulation, for example, determining whether the number of accessed UEs is consistent;
若是， 则仿真评估装置基于在步骤 310中获得的各 UE的 TBS信息和调度频率 β , 分 别确定每一个 UE 的 ΟΤΑ 和 Service 数据， 如， 针对某一个 UE , OTA = Service = TBSueid * uclA , 单位 kbit/s。 If so, the simulation evaluation device determines the ΟΤΑ and Service data of each UE based on the TBS information and the scheduling frequency β of each UE obtained in step 310, for example, for a certain UE, OTA = Service = TBS ueid * uclA , Unit kbit/s.
否则， 则仿真评估装置先基于在步骤 310中获得的各 UE的 TBS信息和调度频率 β以 及比例因子， 分别确定每一个 UE的 ΟΤΑ, 其中， 所谓的比例因子为动态预仿真时每小区 接入最大 UE数与静态仿真时每小区接入最大 UE数的比值； 然后， 仿真评估装置再基于 各 UE的 ΟΤΑ、 静态预仿真时每小区接入最大 UE数、 静态仿真时釆用的***带宽和动态 预仿真时调度每 UE最大分配的 PRB数目， 分别确定每一个 UE的 Service数据。  Otherwise, the simulation evaluation apparatus first determines the ΟΤΑ of each UE based on the TBS information and the scheduling frequency β of each UE and the scale factor obtained in step 310, where the so-called scale factor is the per-cell access during dynamic pre-simulation. The ratio of the maximum number of UEs to the maximum number of UEs accessed per cell during static simulation; then, the simulation evaluation device is based on the UEs, the maximum number of UEs per cell access during static pre-simulation, and the system bandwidth used during static simulation. The maximum number of PRBs allocated per UE is scheduled during dynamic pre-simulation, and the service data of each UE is determined separately.
如， 本实施例中， 假设动态预仿真时釆用的***带宽为 N_RB , 表示为***带宽包含 的 PRB数目， 每小区接入最大 UE数为 UE_NUM_INTERFACE, 本次静态仿真时釆用的 ***带宽为 N_RB ,表示为***带宽包含的 PRB数目，调度每 UE最大分配的 PRB数目为 N RB UE , 每小区接入最大 UE数为 UE_NUM_CURRENT , 当前 UE拟合后的 OTA表示 为 OTAJJEn , 当前 UE 拟合后的 Service 表示为 ServiceJJEn , 比例因子表示为 FACTOR UE； 则针对某一个 UE , OTA UEn = TBS^id * Aeid * FACTOR UE； FACTOR UE = (UE NUM INTERFACE I UE NUM CURRENT) ； 当 满 足 UE NUM CURRENT < (N_RB / N_RB_UE)条件时， UE速率将受限于调度每 UE最大分 配的 PRB 数目 N_RB_UE , 此时， Service_UEn = OTA UEn* UE NUM CURRENT * N RB UE I N RB; ***包含的 RRB数目和每个 UE能够分配的最大 RRB数目决定了一个 子帧内能够调度的最大 UE数， 而 UE_NUM_CURRENT > (N RB I N_RB_UE)这种情况下 已经是负荷较重的情况， 而在实际的静态仿真中， 通常不会超过此种情况进行仿真。 For example, in this embodiment, it is assumed that the system bandwidth used in the dynamic pre-simulation is N_RB, which is expressed as the number of PRBs included in the system bandwidth, and the maximum number of UEs per cell access is UE_NUM_INTERFACE, and the system bandwidth used in this static simulation is N_RB is expressed as the number of PRBs included in the system bandwidth. The maximum number of PRBs allocated per UE is N RB UEs. The maximum number of UEs per cell access is UE_NUM_CURRENT. The current UE's fitted OTA is represented as OTAJJEn. After the current UE is fitted, The Service is represented as ServiceJJEn and the scale factor is represented as FACTOR UE; then for a UE, OTA UEn = TBS ^id * Aeid * FACTOR UE; FACTOR UE = (UE NUM INTERFACE I UE NUM CURRENT) ; when UE NUM CURRENT is satisfied < (N_RB / N_RB_UE) condition, the UE rate will be limited by the number of scheduled maximum number of PRBs per UE N_RB_UE, at this time, Service_UEn = OTA UEn* UE NUM CURRENT * N RB UE IN RB; the number of RRBs included in the system and each The maximum number of RRBs that the UE can allocate determines the maximum number of UEs that can be scheduled in one subframe, and UE_NUM_CURRENT > (N RB I N_RB_UE) is already a heavy load situation. In static simulations, simulations are usually not exceeded.
