本发明涉及网络评估，特别是一种利用率基线值估计方法及装置。The invention relates to network evaluation, in particular to a method and device for estimating a baseline value of utilization.
背景技术Background technique
网络利用率是评估网络无线资源负荷的关键性指标，对网络建设和扩容提供了重要的参考价值。Network utilization is a key indicator for evaluating network wireless resource load, and provides important reference value for network construction and capacity expansion.
对于GSM系统，在其资源利用率的计算中引入利用率基线值(K值)，是为了表征一定业务信道总数的条件下系统能够提供的最大话务量的比例。GSM系统以爱尔兰-B模型为基础给出了利用率基线值，确定了系统稳定可用资源上限，并据此折算出GSM现网利用率。For the GSM system, the utilization baseline value (K value) is introduced in the calculation of resource utilization to represent the proportion of the maximum traffic that the system can provide under the condition of a certain total number of service channels. Based on the Irish-B model, the GSM system provides a baseline value of utilization rate, determines the upper limit of stable and available resources of the system, and converts the utilization rate of the existing GSM network accordingly.
而对于LTE(长期演进)系统，采用物理资源的占用情况来评估LTE系统的网络利用率。LTE系统的物理载频资源按照时间和频率两个维度被分割为多个资源块，其中控制信道最小资源分配单元为CCE(控制信道单元)，而业务信道最小资源分配单元为PRB(物理资源块)。因此LTE系统的无线资源利用率可以考虑统计时间内，小区忙时控制信道CCE占用率和业务信道PRB利用率来评估。For the LTE (Long Term Evolution) system, the occupation of physical resources is used to evaluate the network utilization of the LTE system. The physical carrier frequency resources of the LTE system are divided into multiple resource blocks according to the two dimensions of time and frequency. ). Therefore, the wireless resource utilization rate of the LTE system can be evaluated by considering the CCE occupancy rate of the control channel and the PRB utilization rate of the traffic channel when the cell is busy within the statistical time.
对于TD-LTE网络利用率的定义如下：The definition of TD-LTE network utilization is as follows:
TD-LTE网络利用率为忙时物理上行共享信道PRB利用率、忙时下行共享信道PDSCHPRB利用率以及忙时下行控制信道CCE利用率的最小值。而利用率都需要考虑利用率基线值(K值)。The TD-LTE network utilization rate is the minimum value of the PRB utilization rate of the physical uplink shared channel during busy time, the PDSCH PRB utilization rate of the downlink shared channel during busy time, and the CCE utilization rate of the downlink control channel during busy time. The utilization rate needs to consider the utilization rate baseline value (K value).
而现有技术中，一般根据经验确定K取值为0.5。In the prior art, the value of K is generally determined to be 0.5 based on experience.
然而，上述确定LTE系统的K取值为0.5主要时考虑建网初期一定系统干扰控制的要求，但这种取经验值的方式与K的合理取值有一定的差距，存在进一步优化的空间。However, the above determination of the K value of the LTE system to be 0.5 mainly considers the requirements of certain system interference control in the early stage of network construction, but this method of obtaining empirical values is far from the reasonable value of K, and there is room for further optimization.

具体实施方式Detailed ways
本发明实施例的利用率基线值估计方法及装置中，利用历史业务数据进行大数据分析，考虑业务量变化趋势或者业务性能变化趋势来估计利用率基线值，相对于现有技术的依据经验值估计，提高了估计精度。In the method and device for estimating the baseline value of the utilization rate in the embodiment of the present invention, the historical business data is used for big data analysis, and the trend of business volume or business performance is considered to estimate the baseline value of the utilization rate. Compared with the empirical value of the prior art estimate, which improves the estimation accuracy.
如图1所示，本发明第一实施例的利用率基线值估计方法包括：As shown in FIG. 1, the method for estimating the utilization baseline value in the first embodiment of the present invention includes:
步骤101，获取待评估区域的历史业务数据；Step 101, obtaining historical business data of the area to be evaluated;
步骤102，根据所述历史业务数据确定用于利用率基线值估计的估计指标；所述估计指标为业务量指标和/或业务性能指标；Step 102, determining an estimated index for estimating the utilization rate baseline value according to the historical business data; the estimated index is a traffic volume index and/or a business performance index;
步骤103，根据所述估计指标的变化趋势确定所述待评估区域的利用率基线估计值。Step 103: Determine the baseline estimated value of the utilization rate of the area to be evaluated according to the change trend of the estimated index.
本发明实施例的利用率基线值估计方法及装置中，利用历史业务数据进行大数据分析，考虑业务量变化趋势和/或业务性能变化趋势来估计利用率基线值，相对于现有技术的依据经验值估计，提高了估计精度。In the method and device for estimating the baseline value of utilization rate in the embodiment of the present invention, historical business data is used for big data analysis, and the trend of business volume change and/or business performance change trend is considered to estimate the baseline value of utilization rate. Compared with the basis of the prior art Empirical value estimation improves estimation accuracy.
本发明具体实施例中使得的历史业务数据可以是所有的历史业务数据，但为了逼近利用率基线值理论值，也可以是选择历史业务数据中高业务量的样本数据。The historical business data used in the specific embodiments of the present invention may be all historical business data, but in order to approach the theoretical value of the utilization rate baseline value, sample data with high traffic volume in the historical business data may also be selected.
这种方式下，本发明第二实施例的利用率基线值估计方法如图2所示，包括：In this manner, the method for estimating the utilization baseline value in the second embodiment of the present invention is shown in Figure 2, including:
步骤1011，获取待评估区域的所有原始历史业务数据；Step 1011, obtaining all original historical business data of the area to be evaluated;
步骤1012，从所述所有原始历史业务数据中按照业务量从大到小的顺序选择部分原始历史业务数据作为所述待评估区域的历史业务数据；Step 1012, selecting part of the original historical business data from all the original historical business data in descending order of business volume as the historical business data of the area to be evaluated;
步骤102，根据所述历史业务数据确定用于利用率基线值估计的估计指标；所述估计指标为业务量指标和/或业务性能指标；Step 102, determining an estimated index for estimating the utilization rate baseline value according to the historical business data; the estimated index is a traffic volume index and/or a business performance index;
步骤103，根据所述估计指标的变化趋势确定所述待评估区域的利用率基线估计值。Step 103: Determine the baseline estimated value of the utilization rate of the area to be evaluated according to the change trend of the estimated index.
本发明具体实施例中，通过从样本数据中删除那些低业务量的样本数据，保留高业务量样本数据，能够更有效的逼近利用率基线值理论值，提高估计精度。In the specific embodiment of the present invention, by deleting the sample data with low traffic volume from the sample data and retaining the sample data with high traffic volume, the theoretical value of the utilization rate baseline value can be approached more effectively, and the estimation accuracy can be improved.
本发明具体实施例中，当待评估区域较大时，可以将待评估区域作为一个整体进行估计，但也可以将待评估区域划分为多个子区域(如以小区为单位进行划分)，然后对各子区域进行利用率基线值，最后利用各子区域的利用率基线值得到对应于待评估区域的利用率基线估计值。In the specific embodiment of the present invention, when the area to be evaluated is relatively large, the area to be evaluated can be estimated as a whole, but the area to be evaluated can also be divided into multiple sub-areas (such as divided in units of cells), and then the Each sub-area carries out the baseline value of the utilization rate, and finally uses the baseline value of the utilization rate of each sub-area to obtain the estimated value of the baseline utilization rate corresponding to the area to be evaluated.
这种方式下，本发明第三实施例的利用率基线值估计方法如图3所示，包括：In this way, the method for estimating the baseline value of the utilization rate in the third embodiment of the present invention is shown in Figure 3, including:
步骤101，获取待评估区域的历史业务数据；Step 101, obtaining historical business data of the area to be evaluated;

步骤1032，根据所有历史业务数据集合各自对应的利用率基线子估计值确定所述待评估区域的利用率基线估计值。Step 1032: Determine the estimated utilization rate baseline value of the area to be evaluated according to the corresponding utilization rate baseline sub-estimation values of all historical service data sets.
本发明第三实施例的利用率基线值估计方法中，将待评估区域划分为多个子区域，然后对每个子区域进行利用率基线值估计，最后利用各子区域的利用率基线估计值得到最终的对应于待评估区域的利用率基线估计值。In the utilization rate baseline value estimation method of the third embodiment of the present invention, the area to be evaluated is divided into multiple sub-areas, and then the utilization rate baseline value is estimated for each sub-area, and finally the utilization rate baseline value of each sub-area is used to obtain the final of corresponds to the baseline estimate of utilization for the area being assessed.
而每一次对子区域进行利用率基线值估计时的数据处理量的峰值大大降低，降低对计算能力的要求。同时，分区域进行计算还能够利用并行的方式计算子区域的利用率基线估计值，能够提高处理速度。However, the peak value of the data processing amount when estimating the utilization baseline value of the sub-area is greatly reduced, reducing the requirement for computing power. At the same time, performing calculations in sub-regions can also calculate the utilization baseline estimation value of the sub-regions in a parallel manner, which can improve the processing speed.
而对于利用多个区域对应的利用率基线子估计值来确定最终的待评估区域的利用率基线估计值可以采用多种方式实现，其中一种方式如下所述：There are many ways to determine the final utilization baseline estimation value of the area to be evaluated by using the utilization baseline sub-estimation values corresponding to multiple areas, one of which is as follows:
根据所有历史业务数据集合各自对应的利用率基线子估计值计算累计分布函数曲线；Calculate the cumulative distribution function curve according to the utilization rate baseline sub-estimation values corresponding to all historical business data sets;
确定所述待评估区域的利用率基线估计值为：所述累计分布函数曲线的取值大于或等于预定门限所对应的利用率基线子估计值。The estimated value of the utilization rate baseline of the area to be evaluated is determined as follows: the value of the cumulative distribution function curve is greater than or equal to the utilization rate baseline sub-estimation value corresponding to the predetermined threshold.
利用率基线估计值的累积分布函数能够表征利用率基线估计值小于或者等于某个数值的概率。The cumulative distribution function of the utilization baseline estimate can characterize the probability that the utilization baseline estimate is less than or equal to a certain value.
在本发明具体实施例中，该预定门限可以设置为如80％，但该取值可以依据需要来设置，如用户对服务质量的容忍度较高时，该门限可以高一些，否则可以低一些。In a specific embodiment of the present invention, the predetermined threshold can be set to, for example, 80%, but the value can be set according to needs, such as when the user has a high tolerance for service quality, the threshold can be higher, otherwise it can be lower .
上述的具体实施例中，在得到估计指标之后，即可根据估计指标的变化趋势确定所述待评估区域的利用率基线估计值，一种可能的方式为：In the above-mentioned specific embodiment, after obtaining the estimated index, the estimated value of the baseline utilization rate of the area to be evaluated can be determined according to the change trend of the estimated index. One possible way is:
根据所述历史业务数据中记录的估计指标，得到所述估计指标随有效RRC连接用户数增长的拟合曲线；According to the estimated index recorded in the historical service data, a fitting curve of the estimated index increasing with the number of effective RRC connection users is obtained;
根据所述拟合曲线确定所述待评估区域的利用率基线估计值。Determining a baseline estimated value of the utilization rate of the area to be evaluated according to the fitted curve.
当所述估计指标为业务量指标时，所述根据所述拟合曲线确定所述待评估区域的利用率基线估计值具体为：When the estimation index is a business volume index, the determination of the estimated value of the baseline utilization rate of the area to be evaluated according to the fitting curve is specifically:
确定利用率基线估计值为所述拟合曲线的波峰对应的网络利用率；或Determining that the utilization rate baseline estimation value is the network utilization rate corresponding to the peak of the fitted curve; or
确定利用率基线估计值为所述拟合曲线上业务量增幅变化率减小的点对应的网络利用率。Determine the estimated value of the baseline utilization rate as the network utilization rate corresponding to the point on the fitting curve where the rate of change in the increase in traffic volume decreases.
而当所述估计指标为业务性能指标时，所述根据所述拟合曲线确定所述待评估区域的利用率基线估计值具体为：And when the estimated index is a service performance index, the determination of the estimated utilization rate baseline value of the area to be evaluated according to the fitting curve is specifically:
确定利用率基线估计值为所述拟合曲线上性能恶化速度增加的点对应的网络利用率。Determine the estimated value of the baseline utilization rate as the network utilization rate corresponding to the point on the fitting curve where the performance deterioration speed increases.
对此说明如下。This is explained below.
在本发明具体实施例中，该业务量指标可以是如下指标中的一个或多个：In a specific embodiment of the present invention, the traffic volume indicator may be one or more of the following indicators:
下行PDSCH PRB利用率、上行PUSCH PRB利用率、下行PDCCH CCE利用率、网络利用率、有效RRC连接最大用户数、有效RRC连接平均用户数、RRC连接最大用户数、RRC连接平均用户数、上行业务信道流量、下行业务信道流量等。Downlink PDSCH PRB utilization rate, uplink PUSCH PRB utilization rate, downlink PDCCH CCE utilization rate, network utilization rate, maximum number of effective RRC connection users, average number of effective RRC connection users, maximum number of RRC connection users, average RRC connection user number, uplink service Channel traffic, downlink service channel traffic, etc.
而业务性能指标可以是如下指标中的一个或多个：The business performance indicators can be one or more of the following indicators:
上行平均速率、上行峰值速率、下行平均速率、下行峰值速率、下行首包排队时长、E-RAB平均排队时延、RRC连接建立成功率以及无线接通率等。Uplink average rate, uplink peak rate, downlink average rate, downlink peak rate, downlink first packet queuing time, E-RAB average queuing delay, RRC connection establishment success rate, wireless connection rate, etc.
而上述的数据都与有效RRC连接用户数密切相关，因此，在本发明具体实施例中，都是得到估计指标随有效RRC连接用户数增长的拟合曲线，然后根据拟合曲线以及估计指标的特性来选择不同的点确定待评估区域的利用率基线估计值。And above-mentioned data are all closely related with effective RRC connection user number, therefore, in the specific embodiment of the present invention, all are to obtain the fitting curve that estimation index increases with effective RRC connection user number, then according to fitting curve and estimation index characteristics to select different points to determine a baseline estimate of utilization for the area to be assessed.
如对于流量而言，当用户数超过一定数值之后，上下行流量和不再提高，而是下降的，因此，当估计指标采用上下行流量和或其他具有类似性能的指标时，可以取所述拟合曲线的波峰对应的网络利用率作为待评估区域的利用率基线估计值。For example, in terms of traffic, when the number of users exceeds a certain value, the sum of uplink and downlink traffic no longer increases, but decreases. Therefore, when the estimated index uses uplink and downlink traffic and or other indicators with similar performance, the above can be taken. The network utilization corresponding to the peak of the fitting curve is used as the baseline estimation value of the utilization of the area to be evaluated.
又如对于流量而言，当用户数超过一定数值之后，下行流量的增加的速度显著降低，因此，当估计指标采用流量变化速度的指标时，可以取拟合曲线上业务量增幅变化率减小的点对应的网络利用率作为待评估区域的利用率基线估计值。Another example is for traffic, when the number of users exceeds a certain value, the increase rate of downlink traffic decreases significantly. Therefore, when the estimation index adopts the index of traffic change speed, the rate of change of business volume increase on the fitting curve can be reduced The network utilization corresponding to the point of is used as the baseline estimation value of the utilization of the area to be evaluated.
又如对于业务性能指标而言，当用户数超过一定数值之后，业务性能是降低的，因此，当估计指标采用业务性能变化速度的指标时，可以取拟合曲线上性能恶化速度增加的点对应的网络利用率作为待评估区域的利用率基线估计值。Another example is that for business performance indicators, when the number of users exceeds a certain value, the business performance will be reduced. Therefore, when the estimated indicator uses the indicator of the speed of business performance change, it can be taken to correspond to the point on the fitting curve where the speed of performance deterioration increases. The network utilization rate of the network is used as the baseline estimation value of the utilization rate of the area to be evaluated.
而当估计指标包括多个时，应该考虑最差的情况下才能满足系统的性能需求，因此所述根据所述估计指标的变化趋势确定所述待评估区域的利用率基线估计值的步骤具体为：However, when there are multiple estimated indicators, the performance requirements of the system should be met only in the worst case. Therefore, the step of determining the baseline estimated value of the utilization rate of the area to be evaluated according to the variation trend of the estimated indicators is specifically as follows: :
确定每一个估计指标各自对应的利用率基线估计中间值；Determine the median utilization rate baseline estimate corresponding to each estimated indicator;
确定所述利用率基线估计值为所有估计指标对应的利用率基线估计中间值中的最小值。It is determined that the utilization rate baseline estimated value is a minimum value among utilization rate baseline estimated intermediate values corresponding to all estimated indicators.
以下对本发明实施例的方法进一步详细说明如下。The method of the embodiment of the present invention is further described in detail below.
当采用不划分区域的方式时，首先从历史业务数据中依据利用率或者上下行流量选取业务量较高的样本点数据(如业务量排名前10％的样本数据)，并画出选择的历史业务数据的用户数-业务量指标以及用户数-业务性能指标打点图。When using the method of not dividing regions, first select the sample point data with high traffic volume (such as the top 10% sample data) from the historical business data according to the utilization rate or upstream and downstream traffic, and draw the selected history The number of users-business volume indicators and the number of users-business performance indicators of business data are plotted.
由于预期的系统服务水平对利用率基线值取值有较大的影响，因此根据业务量指标确定利用率基线值估计值的方法主要分为两种：Since the expected system service level has a great influence on the value of the baseline value of the utilization rate, there are mainly two methods for determining the estimated value of the baseline value of the utilization rate based on the business volume index:
用适当的拟合曲线对打点图中的样本点进行拟合，取某个业务量指标拟合曲线的波峰能够达到的利用率值作为待评估区域利用率基线值的估计值。以及Use an appropriate fitting curve to fit the sample points in the dotted graph, and take the utilization rate value that can be achieved by the peak of the fitting curve of a certain business volume index as the estimated value of the baseline value of the utilization rate of the area to be evaluated. as well as
用适当的拟合曲线对打点图中的样本点进行拟合，取某个业务量指标拟合曲线的增幅变缓点处能够达到的利用率值作为待评估区域利用率基线值的估计值。Use an appropriate fitting curve to fit the sample points in the plot, and take the utilization rate value that can be achieved at the slowing point of the fitting curve of a certain business volume index as the estimated value of the baseline value of the utilization rate of the area to be evaluated.
而根据业务性能指标确定利用率基线估计值的方式则采用如下方式：The way to determine the estimated value of the utilization baseline based on the business performance indicators is as follows:
用适当的拟合曲线对打点图中的样本点进行拟合，取某个业务性能指标拟合曲线的明显恶化点处的利用率值作为待评估区域利用率基线估计值。Use an appropriate fitting curve to fit the sample points in the plot, and take the utilization rate value at the obvious deterioration point of the fitting curve of a certain business performance index as the estimated value of the baseline utilization rate of the area to be evaluated.
至此即可确定待评估区域的利用率基线估计值。At this point, a baseline estimate of utilization for the area to be assessed can be determined.
当采用划分区域的方式时，其差异仅在于需要综合各个子区域的利用率基线估计值来得到整个区域的利用率基线估计值，如：When the method of dividing regions is adopted, the only difference is that the utilization baseline estimates of each sub-region need to be integrated to obtain the utilization baseline estimates of the entire region, such as:
取各子区域的利用率基线估计值的均值作为待评估区域的利用率基线估计值；或Take the mean value of the utilization rate baseline estimates of each sub-area as the utilization rate baseline estimate of the area to be evaluated; or
将各子区域的利用率基线估计值从大到小排序，取子区域Y％(如60％等)处的利用率基线估计值作为待评估区域的利用率基线估计值。Sort the estimated utilization rate baselines of each sub-area from large to small, and take the estimated utilization rate baseline value at sub-area Y% (such as 60%) as the estimated utilization rate baseline value of the area to be evaluated.
