现有的均在均衡方法为操作人员人工分析小区负荷量，并通过手动调整负荷均衡参数将高负荷小区的负荷均衡至周边的一些低负荷小区。这些高负荷小区的确定仅仅依据操作人员的经验，接收负荷的低负荷小区的确定，也仅依靠小区间的固定方位，并未对高负荷小区及周边的同覆盖小区的指标进行量化分析，因此，这种方案存在随意性和不准确性。此外，现有的负荷均衡方法为传统的人工分析，手动处理，这种方法造成负荷均衡的效率低，无法应对负荷变化。In the existing equalization method, the operator manually analyzes the load of the cell, and manually adjusts the load balancing parameters to balance the load of the high-load cell to some surrounding low-load cells. The determination of these high-load cells is only based on the experience of operators, and the determination of low-load cells that receive loads only depends on the fixed orientation between cells, and no quantitative analysis has been performed on the indicators of high-load cells and surrounding cells with the same coverage. , this scheme has randomness and inaccuracy. In addition, the existing load balancing method is traditional manual analysis and manual processing, which results in low efficiency of load balancing and cannot cope with load changes.

Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
图1示出了本发明第一实施例的一种负荷均衡方法的流程图，如图1所示，该方法包括以下步骤：Fig. 1 shows a flow chart of a load balancing method according to the first embodiment of the present invention. As shown in Fig. 1, the method includes the following steps:
步骤110：采集各小区的运行数据。Step 110: Collect the operation data of each cell.
小区的运行数据包括小区的性能数据、测量报告和网络配置参数。其中，网元的性能数据相当于网络指标，用于表征网络的运行状况，包含接入小区的负荷类参数，例如，无线利用率、接入用户数等。测量报告是小区的网络信号测量统计文件，用于测量无线网络的质量，测量报告是用户在进行业务时，不断上报至负荷均衡系统的。测量报告可以反映出小区的覆盖情况，以及小区与邻区间的相互关联情况。网络配置参数是小区的网络配置参数，用于控制切换、重选、负荷均衡等各种无线功能。The operating data of the cell includes the performance data of the cell, measurement reports and network configuration parameters. Among them, the performance data of the network element is equivalent to the network index, which is used to characterize the operation status of the network, including the load parameters of the access cell, such as wireless utilization rate, the number of access users, and so on. The measurement report is the network signal measurement statistical file of the cell, which is used to measure the quality of the wireless network. The measurement report is continuously reported to the load balancing system by the user when performing services. The measurement report can reflect the coverage of the cell and the correlation between the cell and its neighbors. The network configuration parameters are the network configuration parameters of the cell, and are used to control various wireless functions such as handover, reselection, and load balancing.
在本步骤中，参数采集的主体是智能均衡优化系统，用于自动实时采集小区运行数据。智能均衡优化系统与负荷端和数据段的无线通信标准相关，现有的无线通信标准主要为LTE网络，相应的智能均衡优化系统为LTE智能均衡优化系统，该系统主要针对LTE通信设备进行优化。下面以LTE智能均衡优化系统为例进行说明。In this step, the main body of parameter collection is the intelligent balance optimization system, which is used to automatically collect the operating data of the community in real time. The intelligent balance optimization system is related to the wireless communication standards of the load end and the data segment. The existing wireless communication standard is mainly the LTE network, and the corresponding intelligent balance optimization system is the LTE intelligent balance optimization system, which is mainly optimized for LTE communication equipment. The following uses an LTE intelligent equalization optimization system as an example for description.
步骤120：根据运行数据确定高负荷小区。Step 120: Determine the high-load cell according to the operation data.
高负荷小区的衡量标准是通过连接高负荷小区的用户数决定的，为了与主要的LTE通信设备供应商提供的负荷均衡无线功能的触发条件保持一致，LTE智能均衡优化系统选择平均激活用户数及小区的无线利用率作为高负荷小区的筛选判断依据。其中，平均激活用户数及小区的无线利用率的选取与具体的设备生产厂家有关，例如，对于华为、中兴等生产厂家的设备，选择平均激活用户数作为高负荷判断指标，对于诺基亚生产的设备，选择小区的无线利用率作为高负荷判断指标。The measurement standard of a high-load cell is determined by the number of users connected to the high-load cell. In order to be consistent with the trigger conditions of the load-balancing wireless function provided by major LTE communication equipment suppliers, the LTE intelligent balance optimization system selects the average number of activated users and The wireless utilization rate of the cell is used as the basis for screening and judging the high-load cell. Among them, the selection of the average number of activated users and the wireless utilization rate of the cell is related to specific equipment manufacturers. , select the wireless utilization rate of the cell as the high load judgment index.
LTE智能均衡优化系统根据运行数据确定小区的平均激活用户数及小区的无线利用率。将平均激活用户数大于第一阈值，和/或，无线利用率大于第二阈值的小区确定为高负荷小区。其中，第一阈值为小区平均激活用户数的门限值，第二阈值为小区无线利用率的门限值。The LTE intelligent balance optimization system determines the average number of activated users of the cell and the wireless utilization rate of the cell according to the operating data. A cell whose average number of active users is greater than a first threshold and/or whose wireless utilization rate is greater than a second threshold is determined as a high-load cell. Wherein, the first threshold is the threshold value of the average number of activated users of the cell, and the second threshold is the threshold value of the wireless utilization rate of the cell.
考虑到小区负荷的变化性，在进行高负荷小区的判定时，各指标均以一定的时间进行统计。例如，以最近15分钟内的平均激活用户数和无线利用率作为小区的判断指标。Considering the variability of cell load, each indicator is counted for a certain period of time when judging a high-load cell. For example, the average number of activated users and wireless utilization rate in the last 15 minutes are used as the judgment indicators of the cell.
步骤130：确定高负荷小区的同覆盖小区。Step 130: Determine the same-coverage cell of the high-load cell.
在本步骤中，高负荷小区的同覆盖小区是指与高负荷小区具有相同覆盖区域的小区。由于测量报告可以反映出小区的覆盖情况，以及小区与邻区间的相互关联情况，因此，同覆盖小区的确定主要依据LLTE智能均衡优化系统采集到的高负荷小区的测量报告。In this step, the same-coverage cell of the high-load cell refers to a cell having the same coverage area as the high-load cell. Since the measurement report can reflect the coverage of the cell and the correlation between the cell and its neighbors, the determination of the cell with the same coverage is mainly based on the measurement report of the high-load cell collected by the LLTE intelligent balance optimization system.
高负荷小区的同覆盖小区包括同频同覆盖小区和异频同覆盖小区，在一些实施例中，考虑到高负荷小区和它的同覆盖小区的同覆盖性，通过在高负荷小区进行同频采样和异频采样实现同覆盖小区的确定。考虑到负荷的变化性，在进行采样时，针对预设时间窗口内高负荷小区进行采样，其中，预设时间窗口表示的是距离当前采样时间最近的一段时间，例如，针对最近15分钟的高负荷小区进行采样。The same-coverage cells of the high-load cell include the same-frequency same-coverage cell and the different-frequency same-coverage cell. In some embodiments, considering the same coverage of the high-load cell and its same-coverage cell, the same-frequency Sampling and inter-frequency sampling realize the determination of cells with the same coverage. Considering the variability of the load, when sampling, samples are taken for high-load cells within a preset time window, where the preset time window represents a period of time closest to the current sampling time, for example, for the most recent 15 minutes of high-load cells The load cells are sampled.
分别计算预设时间窗口内，高负荷小区同频测量的采样点总数和异频测量的采样点总数，根据同频测量的采样点总数中，各邻区的采样点个数所占的比例，确定高负荷小区的同频同覆盖小区。即，当邻区的采样点个数占同频测量的采样点总数的比例大于第三阈值时，确定该邻区为高负荷小区的同频同覆盖小区。其中，第三阈值是本领域的技术人员在实施本发明实施例的过程中，人为设定的一个数值。根据异频测量的采样点总数中，各邻区的采样点个数所占的比例，确定高负荷小区的异频同覆盖小区。即，当邻区的采样点个数占异频测量的采样点总数的比例大于第四阈值时，确定该邻区为高负荷小区的异频同覆盖小区。其中，第四阈值是本领域的技术人员在实施本发明实施例的过程中，人为设定的一个数值，第四阈值与第三阈值可以设置为相同的值，也可以设置为不同的值。将同频同覆盖小区和异频同覆盖小区作为高负荷小区的同覆盖小区。In the preset time window, the total number of sampling points for co-frequency measurement and the total number of sampling points for inter-frequency measurement in high-load cells are calculated respectively. Determine the same-frequency and same-coverage cells of high-load cells. That is, when the ratio of the number of sampling points in the neighboring cell to the total number of sampling points measured at the same frequency is greater than the third threshold, it is determined that the neighboring cell is a cell with the same frequency and the same coverage as a high-load cell. Wherein, the third threshold is a value artificially set by those skilled in the art during the implementation of the embodiment of the present invention. According to the proportion of the number of sampling points in each neighboring cell in the total number of sampling points measured in different frequencies, the cell with different frequency and same coverage in the high-load cell is determined. That is, when the ratio of the number of sampling points in the neighboring cell to the total number of sampling points measured in different frequencies is greater than the fourth threshold, it is determined that the neighboring cell is a cell with different frequencies and the same coverage of a high-load cell. Wherein, the fourth threshold is a value artificially set by those skilled in the art during the implementation of the embodiments of the present invention, and the fourth threshold and the third threshold may be set to the same value or different values. The same-frequency and same-coverage cells and the different-frequency and same-coverage cells are used as the same-coverage cells of high-load cells.
步骤140：根据高负荷小区中待均衡负荷的负荷类型，生成相应的负荷均衡策略。Step 140: Generate a corresponding load balancing strategy according to the load type of the load to be balanced in the high-load cell.
高负荷小区中待均衡负荷的负荷类型包括空闲态负荷和激活态负荷，在进行负荷均衡时，针对空闲态负荷和激活态负荷采取的负荷均衡方式不同，因此，针对高负荷小区中待均衡的负荷类型，并结合同覆盖小区的均衡参数，生成相应的负荷均衡策略。The types of loads to be balanced in high-load cells include idle loads and active loads. When performing load balancing, the load balancing methods for idle loads and active loads are different. Therefore, for high-load cells to be balanced Load type, combined with the balance parameters of the same coverage cell, generate the corresponding load balance strategy.
步骤150：将负荷均衡策略发送至高负荷小区，以使高负荷小区与同覆盖小区进行负荷均衡。Step 150: Send the load balancing strategy to the high-load cell, so that the high-load cell performs load balancing with the cells with the same coverage.
LTE智能均衡优化系统将步骤140生成的负荷均衡策略发送到高负荷小区，高负荷小区根据负荷均衡策略调整相应的均衡参数，调整均衡参数之后，高负荷小区中的部分负荷从高负荷小区迁出，并连接到同覆盖小区。The LTE intelligent balancing optimization system sends the load balancing strategy generated in
本发明实施例根据采集的各小区的运行数据确定高负荷小区，并确定高负荷小区的同覆盖小区，从而为高负荷小区及高负荷小区的同覆盖小区的确定提供量化分析的指标；此外，在确定高负荷小区及高负荷小区的同覆盖小区时，设定了时间粒度，充分考虑到了小区负荷的变化，保证了小区分析的准确性。根据高负荷小区中待均衡负荷的负荷类型，生成相应的负荷均衡策略，并将该策略发送至高负荷小区，从而实现了高效率的负荷均衡。The embodiment of the present invention determines the high-load cell according to the collected operation data of each cell, and determines the same-coverage cell of the high-load cell, thereby providing quantitative analysis indicators for the determination of the high-load cell and the same-coverage cell of the high-load cell; in addition, When determining the high-load cell and the same-coverage cell of the high-load cell, the time granularity is set, and the change of the cell load is fully considered to ensure the accuracy of the cell analysis. According to the load type of the load to be balanced in the high-load cell, a corresponding load-balancing policy is generated, and the policy is sent to the high-load cell, thereby realizing high-efficiency load balancing.
图2示出了本发明第二实施例的一种负荷均衡方法的流程图，在本实施例中，同覆盖小区为同频同覆盖小区，高负荷小区中待均衡负荷的负荷类型为空闲态负荷，本实施例包括如图2所示的以下步骤：Fig. 2 has shown the flow chart of a kind of load balancing method of the second embodiment of the present invention, and in this embodiment, the sub-district with the same coverage is the same coverage sub-district with the same frequency, and the load type to be balanced load in the high-load sub-district is idle state load, the present embodiment includes the following steps as shown in Figure 2:
步骤210：采集各小区的运行数据。Step 210: Collect the operation data of each cell.
步骤220：根据运行数据确定高负荷小区。Step 220: Determine the high-load cell according to the operation data.
步骤230：计算预设时间窗口内，高负荷小区同频测量的采样点总数。Step 230: Calculate the total number of sampling points for co-frequency measurement of high-load cells within a preset time window.
步骤240：根据同频测量的采样点总数中，各邻区的采样点个数所占的比例，确定高负荷小区的同频同覆盖小区。Step 240: According to the proportion of the number of sampling points in each neighboring cell in the total number of sampling points measured at the same frequency, determine the same-frequency and same-coverage cell of the high-load cell.
步骤210至步骤240的具体说明请参阅实施例一种的步骤110至步骤230，在此不再赘述。For specific descriptions of
步骤250：对同覆盖小区中的所有小区，按照小区的采样点个数占同频测量的采样点总数的比例进行降序排列，得到同频邻区表。Step 250: Arrange all the cells in the same-coverage cell in descending order according to the ratio of the number of sampling points in the cell to the total number of sampling points measured at the same frequency, to obtain a list of adjacent cells at the same frequency.
小区的采样点个数占同频测量的采样点总数的比例越多，说明同覆盖的区域越大，在进行负荷均衡时，越容易将高负荷小区中的负荷均衡至该同覆盖小区。The larger the ratio of the number of sampling points in the cell to the total number of sampling points measured in the same frequency, the larger the area covered by the same coverage, and the easier it is to balance the load in the high-load cell to the same coverage cell when performing load balancing.
步骤260：按照同频邻区表的排列顺序，依次选取前N个平均激活用户数小于或等于第五阈值，和/或，无线利用率小于或等于第六阈值的小区，生成新的同频邻区表。Step 260: According to the arrangement order of the same-frequency neighbor cell table, sequentially select the first N cells whose average number of active users is less than or equal to the fifth threshold, and/or, the wireless utilization rate is less than or equal to the sixth threshold, and generate new same-frequency neighbor list.
在本步骤中，第五阈值和第六阈值用于表示邻区的负荷门限值，即，平均激活用户数小于或等于第五阈值，和/或，无线利用率小于或等于第六阈值的小区，认为没有达到小区的门限值，在保证小区通信质量的前提下，还可以接收更多的负荷。其中，N是一个大于0的自然数，N的选取与高负荷小区中待均衡的负荷数量有关系。例如，如果高负荷小区中待均衡的负荷很少，仅选择一个同频同覆盖小区便可以容纳这部分负荷，则将N的值设置为1。在具体实施方式中，N可以由本领域的技术人员根据高负荷小区的负荷状况人为设定，本发明并不对N的值进行限定。In this step, the fifth threshold and the sixth threshold are used to represent the load thresholds of neighboring cells, that is, the average number of active users is less than or equal to the fifth threshold, and/or the wireless utilization rate is less than or equal to the sixth threshold The cell is considered to have not reached the threshold value of the cell, and can receive more load under the premise of ensuring the communication quality of the cell. Wherein, N is a natural number greater than 0, and the selection of N is related to the load quantity to be balanced in the high-load cell. For example, if there is little load to be balanced in a high-load cell, and only one cell with the same frequency and coverage can accommodate this part of the load, then the value of N is set to 1. In a specific implementation manner, N may be artificially set by those skilled in the art according to the load status of a high-load cell, and the present invention does not limit the value of N.
新的同频邻区表中，仅包含可以容纳负荷的同频同覆盖小区。In the new co-frequency neighbor cell list, only co-frequency and co-coverage cells that can accommodate the load are included.
步骤270：生成高负荷小区与新的同频邻区表中的每一小区的重选偏置参数。Step 270: Generate reselection bias parameters between the high-load cell and each cell in the new intra-frequency neighbor cell list.
重选偏置参数用于表示两个小区之间进行负荷切换的难以程度。两个小区之间的重选偏置参数越大，越容易实现两个小区之间的负荷均衡。在本步骤中，重选偏置参数用于表示高负荷小区与同频同覆盖小区之间的重选偏置参数。The reselection bias parameter is used to indicate the difficulty of load switching between two cells. The larger the reselection bias parameter between the two cells is, the easier it is to achieve load balancing between the two cells. In this step, the reselection bias parameter is used to represent the reselection bias parameter between the high load cell and the same frequency and same coverage cell.
步骤280：将小于预设参数值的重选偏置参数调整至预设参数值。Step 280: Adjust the reselection bias parameter smaller than the preset parameter value to the preset parameter value.
预设参数值是高负荷小区与同频同覆盖小区之间的重选偏置参数的最大值，该值是一个大于0的自然数。当高负荷小区与某一同频同覆盖小区之间的重选偏置参数小于预设参数值时，则将高负荷小区与该同频同覆盖小区之间的重选偏置参数调整至预设参数值，以便于实现高负荷小区与该同频同覆盖小区之间的负荷均衡。在一种具体的实施方式中，预设参数值为4，则在进行重选偏置参数调整时，将所有与高负荷小区之间的重选偏置参数低于4的重选偏置参数调整为4。The preset parameter value is the maximum value of the reselection bias parameter between the high load cell and the same frequency and same coverage cell, and this value is a natural number greater than 0. When the reselection bias parameter between the high-load cell and a same-frequency and same-coverage cell is less than the preset parameter value, adjust the re-selection bias parameter between the high-load cell and the same-frequency and same-coverage cell to the preset value Parameter value, so as to realize the load balance between the high-load cell and the same-frequency and same-coverage cell. In a specific implementation manner, the preset parameter value is 4, then when adjusting the reselection bias parameter, all the reselection bias parameters between the high-load cell and the reselection bias parameter lower than 4 are set to Adjust to 4.
步骤290：将负荷均衡策略发送至高负荷小区，以使高负荷小区与同频同覆盖小区进行负荷均衡。Step 290: Send the load balancing strategy to the high-load cell, so that the high-load cell performs load balancing with the same-frequency and same-coverage cell.
将步骤250至步骤280确定的负荷均衡策略发送至高负荷小区，以使高负荷小区根据该负荷均衡策略调整相关的小区重选参数，实现空闲态负荷均衡至同频同覆盖小区。The load balancing strategy determined in
本发明实施例通过调整高负荷小区与同频同覆盖小区之间的重选偏置参数实现负荷均衡，从而实现了将高负荷小区的空闲态负荷均衡至同频同覆盖小区。In the embodiment of the present invention, load balance is realized by adjusting the reselection bias parameters between the high-load cell and the same-frequency and same-coverage cell, thereby realizing load balancing of the idle state load of the high-load cell to the same-frequency and same-coverage cell.
图3示出了本发明第三实施例的一种负荷均衡方法的流程图，在本实施例中，同覆盖小区为异频同覆盖小区，高负荷小区中待均衡负荷的负荷类型为空闲态负荷，本实施例包括如图3所示的以下步骤：Fig. 3 shows a flow chart of a load balancing method according to the third embodiment of the present invention. In this embodiment, the cells with the same coverage are cells with different frequencies and the same coverage, and the load type to be balanced in the high-load cells is idle state load, the present embodiment includes the following steps as shown in Figure 3:
步骤310：采集各小区的运行数据。Step 310: Collect the operation data of each cell.
步骤320：根据运行数据确定高负荷小区。Step 320: Determine the high-load cell according to the operation data.
步骤330：计算预设时间窗口内，高负荷小区异频测量的采样点总数。Step 330: Calculate the total number of sampling points for inter-frequency measurement of high-load cells within a preset time window.
步骤340：根据异频测量的采样点总数中，各邻区的采样点个数所占的比例，确定高负荷小区的异频同覆盖小区。Step 340: According to the proportion of the number of sampling points in each neighboring cell in the total number of sampling points measured in different frequencies, determine the different-frequency and same-coverage cell of the high-load cell.
步骤310至步骤340的具体说明请参阅实施例一种的步骤110至步骤230，在此不再赘述。For specific descriptions of
步骤350：确定异频同覆盖小区中，与高负荷小区距离最近的K个小区中，同一频率最多的小区。Step 350: Determine the cell with the most same frequency among the K cells closest to the high-load cell among the cells with different frequency and same coverage.
在本步骤中，K是一个大于0的自然数，确定异频同覆盖小区中，与高负荷小区距离最近的K个小区采用的是K近邻算法，该算法是一种机器学习算法，通过各异频同频小区与高负荷小区之间的距离，确定K个与高负荷小区距离最近的异频同覆盖小区。In this step, K is a natural number greater than 0. It is determined that among the cells with different frequencies and the same coverage, the K cells closest to the high-load cell use the K nearest neighbor algorithm. This algorithm is a machine learning algorithm. Determine the distance between the same-frequency cell and the high-load cell, and determine K cells with different frequencies and the same coverage that are closest to the high-load cell.
在K各异频同覆盖小区中，每一小区都有相应的频率，在进行负荷切换时，优先考虑同一频率最多的小区。In K cells with different frequencies and the same coverage, each cell has a corresponding frequency, and the cell with the most same frequency is given priority when switching loads.
步骤360：根据同一频率最多的小区对应的频率确定该小区的重选优先级。Step 360: Determine the reselection priority of the cell according to the frequency corresponding to the cell with the most same frequency.
小区的重选优先级与小区的频率有关，例如，在LTE中，F频段的小区的重选优先级为5，D频段的小区的重选优先级为7。小区的重选优先级越高，越不容易实现负荷均衡。The reselection priority of a cell is related to the frequency of the cell. For example, in LTE, the reselection priority of a cell in the F frequency band is 5, and the reselection priority of a cell in the D frequency band is 7. The higher the reselection priority of the cell, the harder it is to achieve load balancing.
步骤370：当高负荷小区的重选优先级高于该小区的重选优先级时，将高负荷小区的重选优先级调整为该小区的重选优先级。Step 370: When the reselection priority of the highly loaded cell is higher than the reselection priority of the cell, adjust the reselection priority of the high loaded cell to the reselection priority of the cell.
为了使高负荷小区的负荷均衡至异频同覆盖小区，将高负荷小区的重选优先级调整为待接收负荷的异频同覆盖小区的重选优先级。In order to balance the load of the high-load cell to the different-frequency and same-coverage cell, the reselection priority of the high-load cell is adjusted to the reselection priority of the different-frequency and same-coverage cell to receive the load.
步骤380：将负荷均衡策略发送至高负荷小区，以使高负荷小区与异频同覆盖小区进行负荷均衡。Step 380: Send the load balancing policy to the high-load cell, so that the high-load cell performs load balancing with the different-frequency and same-coverage cell.
本发明实施例通过调整高负荷小区与同频同覆盖小区之间的重选优先级实现负荷均衡，从而实现了将高负荷小区的空闲态负荷均衡至异频同覆盖小区。In the embodiments of the present invention, load balancing is realized by adjusting the reselection priorities between high-load cells and cells with the same frequency and same coverage, thereby realizing the load balance of the idle state of the high-load cells to the cells with different frequencies and the same coverage.
图4示出了本发明第四实施例的一种负荷均衡方法的流程图，在本发明实施例中，高负荷小区中待均衡负荷的负荷类型为激活态负荷，本发明实施例包括如图4所示的如下步骤：Fig. 4 shows a flow chart of a load balancing method according to the fourth embodiment of the present invention. In the embodiment of the present invention, the load type of the load to be balanced in the high-load cell is active load, and the embodiment of the present invention includes 4 shows the following steps:
步骤410：采集各小区的运行数据。Step 410: Collect the operation data of each cell.
步骤420：根据运行数据确定小区的平均激活用户数及小区的无线利用率。Step 420: Determine the average number of active users of the cell and the wireless utilization rate of the cell according to the operating data.
步骤430：将平均激活用户数大于第一阈值，和/或，无线利用率大于第二阈值的小区确定为高负荷小区。Step 430: Determine a cell whose average number of active users is greater than a first threshold, and/or whose radio utilization rate is greater than a second threshold, as a high-load cell.
步骤440：确定高负荷小区的同覆盖小区。Step 440: Determine the co-coverage cell of the high load cell.
步骤410至步骤440的具体说明请参阅实施例一中的步骤110至步骤130，在此不再赘述。For specific descriptions of
步骤450：计算同覆盖小区中每一小区的平均激活用户数与第一阈值的第一差值，以及，同覆盖小区中每一小区的无线利用率与第二阈值的第二差值。Step 450: Calculate the first difference between the average number of active users of each cell in the same coverage cell and the first threshold, and the second difference between the wireless utilization rate of each cell in the same coverage cell and the second threshold.
步骤460：获取第一差值的最小值及第二差值的最小值。Step 460: Obtain the minimum value of the first difference and the minimum value of the second difference.
第一差值的最小值和第二差值的最小值作为高负荷小区进行负荷均衡的判决门限值。The minimum value of the first difference value and the minimum value of the second difference value are used as decision thresholds for performing load balancing in high-load cells.
步骤470：将第一阈值和第二阈值分别更新为第一差值的最小值和第二差值的最小值。Step 470: Update the first threshold and the second threshold to the minimum value of the first difference and the minimum value of the second difference, respectively.
将用于表示高负荷小区平均激活用户数门限值的第一阈值，和用于表示高负荷小区无线利用率门限值的第二阈值分别更新为第一差值的最小值和第二差值的最小值，以便于高负荷小区的负荷均衡。Update the first threshold value used to represent the threshold value of the average number of activated users of the high-load cell and the second threshold value used to represent the threshold value of the wireless utilization rate of the high-load cell to the minimum value of the first difference and the second difference The minimum value of the value is to facilitate load balancing of high-load cells.
步骤480：根据更新后的第一阈值以及高负荷小区的平均激活用户数确定高负荷小区的待均衡用户数。Step 480: Determine the number of users to be balanced in the high-load cell according to the updated first threshold and the average number of activated users in the high-load cell.
当负荷评价指标为无线利用率时，无法确定待均衡用户时，因此，在这种情况下，不需要设置待均衡用户数。当负荷评价指标为平均激活用户数时，高负荷小区的待均衡用户数＝h-k+L，其中，h表示高负荷小区的平均激活用户数，k表示更新后的第一阈值，L表示高负荷小区中容纳负荷的冗余，例如，在高负荷小区中，能够容纳的负荷数为10，将冗余设置为2，则当高负荷小区中的负荷数达到8时，即进行负荷均衡。When the load evaluation index is the wireless utilization rate, it is impossible to determine the users to be balanced. Therefore, in this case, it is not necessary to set the number of users to be balanced. When the load evaluation index is the average number of active users, the number of users to be balanced in the high-load cell = h-k+L, where h represents the average number of active users in the high-load cell, k represents the updated first threshold, and L represents Redundancy to accommodate loads in a high-load community, for example, in a high-load community, the number of loads that can be accommodated is 10, and the redundancy is set to 2, then when the number of loads in a high-load community reaches 8, load balancing will be performed .
步骤490：将负荷均衡策略发送至高负荷小区，以使高负荷小区与同覆盖小区进行负荷均衡。Step 490: Send the load balancing policy to the high-load cell, so that the high-load cell performs load balancing with the cells with the same coverage.
本发明实施例通过计算高负荷小区的切换参数，生成高负荷小区中激活态负荷的负荷均衡策略，从而实现了高负荷小区中激活态负荷的均衡。In the embodiment of the present invention, by calculating the switching parameters of the high-load cell, a load balancing strategy for the active load in the high-load cell is generated, thereby realizing the balance of the active load in the high-load cell.
