Translated fromChinese技术领域technical field
本发明涉及通信技术领域，特别涉及一种小区扩容方法及网络设备。The present invention relates to the field of communication technology, in particular to a cell expansion method and network equipment.
背景技术Background technique
无线通信网络包括多个地面基站，当终端设备位于一个基站的某一小区时，该终端设备可以访问该基站。随着访问该基站的终端设备的数量增加，该基站可能无法承载较多的终端设备同时进行通信，这种情况下就需要对网络进行扩容。The wireless communication network includes a plurality of terrestrial base stations, and when the terminal equipment is located in a certain cell of a base station, the terminal equipment can visit the base station. As the number of terminal devices accessing the base station increases, the base station may not be able to carry more terminal devices to communicate at the same time. In this case, the network needs to be expanded.
现有的一种网络扩容方式是增加基站频率，即增加基站发射/接收信号的频点，从而使得基站可以在同一时间与更多的终端设备进行通信，实现网络扩容的目的。目前增加基站频率的实现方式例如有独立天馈覆盖方式，即不同频段对应的无线射频单元(RadioUnit，RU)各自接不同的天线。独立天馈覆盖方式较难实现同覆盖区域，即较难实现覆盖同一个区域，且网络扩容是根据原始设置的网络工作参数(例如天线的方位角等)或者天资采集数据(例如终端设备初始采集的天线的方位角、下倾角等)作为参考依据，再通过查询与网络工作参数或天资采集数据匹配的异频段小区进行扩容。An existing network expansion method is to increase the frequency of the base station, that is, increase the frequency point of the base station to transmit/receive signals, so that the base station can communicate with more terminal devices at the same time to achieve the purpose of network expansion. At present, an implementation method of increasing the base station frequency includes, for example, an independent antenna feeder coverage method, that is, radio frequency units (RadioUnits, RUs) corresponding to different frequency bands are respectively connected to different antennas. The independent antenna feeder coverage method is difficult to achieve the same coverage area, that is, it is difficult to achieve coverage in the same area, and the network expansion is based on the original set network working parameters (such as the azimuth angle of the antenna, etc.) or talent collection data (such as the initial collection of terminal equipment Antenna azimuth, downtilt, etc.) as a reference basis, and then expand the capacity by querying different frequency band cells that match the network working parameters or talent collection data.
但是天线的方位角可能会被更改，那么在进行小区扩容时仍然采用网络工作参数或天资采集数据确定匹配的异频段小区的准确度就较低，扩容效果较差。However, the azimuth angle of the antenna may be changed, so the accuracy of determining the matching inter-frequency band cell by still using the network working parameters or talent collection data during cell expansion is low, and the expansion effect is poor.

具体实施方式Detailed ways
为使本发明的目的、技术方案和优点更加清楚明白，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
目前独立天馈覆盖方式较难实现同一个区域，且网络扩容是根据原始设置的网络工作参数(例如天线的方位角等)或者天资采集数据(例如终端设备初始采集的天线的方位角、下倾角等)作为参考依据，再通过查询与网络工作参数或天资采集数据匹配的异频段小区进行扩容。但是天线的方位角可能会被更改，那么在进行小区扩容时仍然采用网络工作参数或天资采集数据确定匹配的异频段小区的准确度就较低，扩容效果较差。At present, it is difficult to achieve the same area with the independent antenna feeder coverage method, and the network expansion is based on the original network working parameters (such as the azimuth angle of the antenna, etc.) etc.) as a reference, and then expand the capacity by querying different frequency band cells that match the network working parameters or talent collection data. However, the azimuth angle of the antenna may be changed, so the accuracy of determining the matching inter-frequency band cell by still using the network working parameters or talent collection data during cell expansion is low, and the expansion effect is poor.
鉴于此，本发明实施例提供了一种小区扩容方法，该方法根据待扩容小区的热点区域也就是业务量较大的区域，与待扩容小区的至少一个异频段邻小区之间的重叠覆盖度，即采样点在待扩容小区的占比，来进一步从至少一个异频段邻小区中选取待扩容小区的异频段目标扩容小区。相较于现有技术通过网络工作参数或天资采集数据来匹配异频段小区来说，本发明实施例由于是根据待扩容小区实际的热点区域与异频段邻小区的重复覆盖度来确定的，所以确定的异频段邻小区准确度较高，从而提高了扩容效果。In view of this, an embodiment of the present invention provides a cell expansion method, which is based on the overlapping coverage between the hotspot area of the cell to be expanded, that is, the area with a large traffic volume, and at least one neighboring cell of a different frequency band of the cell to be expanded , that is, the proportion of sampling points in the cell to be expanded, to further select a different frequency band target expansion cell of the cell to be expanded from at least one different frequency band neighboring cell. Compared with the prior art to match cells in different frequency bands by collecting data through network working parameters or talents, the embodiment of the present invention is determined according to the overlapping coverage between the actual hotspot area of the cell to be expanded and the adjacent cells in different frequency bands. The determined adjacent cells in different frequency bands have higher accuracy, thereby improving capacity expansion effect.
本发明实施例中，MR数据是用户终端发起业务与基站通信过程中通过网络通信设备采集的用户通信的真实测量结果。MR数据涵盖了小区的网络覆盖情况、业务质量、小区或载波发射功能等指标。通过采集全网的MR数据，分析MR数据，可以发现当前用户的分布状况，也可以评估小区覆盖情况，发现网络存在的问题，如网络中覆盖不佳的情况、用户掉线等问题，从而优化网络，提升用户使用体验。In the embodiment of the present invention, the MR data is the real measurement result of the user communication collected by the network communication device during the communication process between the user terminal initiating a service and the base station. MR data covers indicators such as the network coverage of the cell, service quality, cell or carrier transmission function, etc. By collecting MR data of the entire network and analyzing the MR data, you can find out the distribution of current users, evaluate the coverage of the cell, and find problems in the network, such as poor coverage in the network and user dropouts, etc., so as to optimize network to improve user experience.
下面结合说明书附图介绍本发明实施例提供的技术方案。The following describes the technical solutions provided by the embodiments of the present invention in conjunction with the drawings in the description.
请参见图1，本发明实施例提供了一种小区扩容方法，该方法可以由网络设备例如基站执行，该方法的具体流程描述如下。Referring to FIG. 1 , an embodiment of the present invention provides a cell expansion method, which can be executed by a network device such as a base station, and the specific process of the method is described as follows.
S101、确定待扩容小区的覆盖范围以及覆盖的至少一个热点区域，每个热点区域的业务量大于第一预设阈值。S101. Determine the coverage of the cell to be expanded and at least one covered hotspot area, where the traffic volume of each hotspot area is greater than a first preset threshold.
要对某个小区进行扩容，首先需要判断该小区是否需要扩容，也就是该小区内访问基站的终端设备的数量是否较多，该基站是否无法承载较多的终端设备同时进行通信，如果该基站无法承载较多的终端设备同时进行通信，则需要对该小区进行扩容。To expand the capacity of a certain cell, it is first necessary to determine whether the cell needs to be expanded, that is, whether the number of terminal devices accessing the base station in the cell is large, and whether the base station cannot carry more terminal devices to communicate at the same time. If the base station If it is unable to carry more terminal devices to communicate at the same time, the cell needs to be expanded.
在具体对某个待扩容小区进行扩容时，也就是将待扩容小区内的较为集中的终端设备(热点区域)的业务分流到其他小区。首先需要判断确定待扩容小区的覆盖范围以及覆盖的至少一个热点区域。本发明实施例中的热点区域是指业务量大于第一预设阈值的区域，也就是业务量较大的区域。When specifically expanding the capacity of a cell to be expanded, that is, the services of relatively concentrated terminal devices (hot spots) in the cell to be expanded are distributed to other cells. Firstly, it is necessary to judge and determine the coverage of the cell to be expanded and at least one hotspot area to be covered. The hotspot area in the embodiment of the present invention refers to an area with a traffic volume greater than a first preset threshold, that is, an area with a large traffic volume.
本发明实施例可以基于MR数据来确定待扩容小区的覆盖范围以及覆盖的至少一个热点区域。MR数据可以反映小区覆盖情况，MR数据落在小区覆盖范围内。例如，覆盖范围可以是一个圆形区域，基站处于该圆形区域的中心。MR数据分析平台通过对MR数据进行分析，从而评估小区覆盖情况。In this embodiment of the present invention, the coverage of the cell to be expanded and at least one covered hotspot area may be determined based on the MR data. The MR data can reflect the coverage of the cell, and the MR data falls within the coverage of the cell. For example, the coverage area may be a circular area with the base station at the center of the circular area. The MR data analysis platform analyzes the MR data to evaluate the coverage of the cell.
MR数据分析平台对MR数据分析时，可以将MR数据划分为M个栅格，M为正整数。一个栅格可以包括至少一条MR数据，也可以不包括MR数据。在划分完毕后，针对每个栅格的采样点的数量来确定待扩容小区的覆盖范围。MR数据分析平台可以根据地理区域将MR数据划分为多个栅格，如图2所示，图2以商洛商南湘河的地理区域为例。可能的实施方式中，栅格的大小可以是50m*50m，以尽量包含较多的采样点。When analyzing MR data, the MR data analysis platform can divide the MR data into M grids, where M is a positive integer. A grid may include at least one piece of MR data, or may not include MR data. After the division is completed, the coverage of the cell to be expanded is determined according to the number of sampling points of each grid. The MR data analysis platform can divide the MR data into multiple grids according to the geographical area, as shown in Figure 2. Figure 2 takes the geographical area of Shangluo Shangnanxiang River as an example. In a possible implementation manner, the size of the grid may be 50m*50m to include as many sampling points as possible.
本发明实施例划分了多个栅格之后，可以根据多个栅格确定待扩容小区的至少一个热点区域。具体地，本发明实施例从多个栅格中选取采样点大于第二预设阈值的至少一个栅格，也就是从多个栅格中选取业务量较大的至少一个栅格。例如，可以以每个栅格内平均采样点数量上浮30％为标准进行至少一个栅格的筛选。筛选至少一个栅格之后，本发明实施例可以对至少一个栅格进行聚类，获得至少一个热点区域。例如，本发明实施例对至少一个栅格进行距离矩阵组合(例如200米之内)，匹配每个栅格内经纬度进行地理化呈现，进而基于选定的至少一个栅格通过聚类算法，最终确定至少一个热点区域，如图3所示。图3中以获得3个热点区域即A区域、B区域、C区域为例。After the multiple grids are divided in the embodiment of the present invention, at least one hotspot area of the cell to be expanded may be determined according to the multiple grids. Specifically, in this embodiment of the present invention, at least one grid whose sampling point is greater than the second preset threshold is selected from the multiple grids, that is, at least one grid with a relatively large traffic volume is selected from the multiple grids. For example, at least one grid may be screened on the basis that the average number of sampling points in each grid increases by 30%. After screening the at least one grid, the embodiment of the present invention may perform clustering on the at least one grid to obtain at least one hotspot area. For example, the embodiment of the present invention performs distance matrix combination (for example, within 200 meters) on at least one grid, matches the latitude and longitude in each grid for geographic presentation, and then uses a clustering algorithm based on the selected at least one grid, and finally Identify at least one hotspot area, as shown in Figure 3. In FIG. 3 , it is taken as an example to obtain three hotspot areas, that is, area A, area B, and area C.
S102、确定待扩容小区的至少一个异频段邻小区，其中，异频段邻小区对应的频段与待扩容小区对应的频段不同。S102. Determine at least one neighboring cell with different frequency bands of the cell to be expanded, where the frequency band corresponding to the neighboring cell with different frequency bands is different from the frequency band corresponding to the cell to be expanded.
本发明实施例是将待扩容小区覆盖的热点区域内的业务量分流给其他小区，以实现扩容的目的。所以，本发明实施例可以确定待扩容小区的至少一个异频段邻小区，以作为待扩容小区的首选异频段目标扩容小区。In the embodiment of the present invention, the traffic in the hotspot area covered by the cell to be expanded is distributed to other cells, so as to realize the purpose of capacity expansion. Therefore, in the embodiment of the present invention, at least one adjacent cell in a different frequency band of the cell to be expanded may be determined as a preferred target expansion cell in a different frequency band of the cell to be expanded.
本发明实施例可以从待扩容小区的多个异频段邻小区中选取至少一个异频段邻小区。具体地，针对待扩容小区的每个异频段邻小区，本发明实施例可以基于操作维护中心(Operation and Maintenance Center，OMC)的切换性能指标数据，确定每个异频段邻小区与待扩容小区之间的异频切换次数，也就是待扩容小区切换至每个异频段邻小区的次数，以及每个异频段邻小区切换至待扩容小区的次数之和，从而根据异频切换次数从待扩容小区的多个异频段邻小区中确定至少一个异频段邻小区。In the embodiment of the present invention, at least one neighboring cell with different frequency bands may be selected from a plurality of neighboring cells with different frequency bands of the cell to be expanded. Specifically, for each adjacent cell in different frequency bands of the cell to be expanded, the embodiment of the present invention may determine the difference between each adjacent cell in different frequency bands and the cell to be expanded based on the handover performance index data of the Operation and Maintenance Center (OMC). The number of inter-frequency handovers between the cells to be expanded, that is, the number of times the cell to be expanded is handed over to each adjacent cell in different frequency bands, and the sum of the number of times each adjacent cell in different frequency bands is handed over to the cell to be expanded, so that the number of handovers from the cell to be expanded to Determine at least one neighboring cell of different frequency bands among the multiple neighboring cells of different frequency bands.
可能的实施方式中，本发明实施例可以将多个异频段邻小区中异频切换次数最大的前N个异频段邻小区确定为至少一个异频段邻小区，N为正整数。例如N为3，也就是本发明实施例可以筛选出3个异频段邻小区作为异频段目标扩容小区，如图4所示，图4以N＝3为例。图4中邻小区即是异频段邻小区，本地小区就是待扩容小区。异频切换次数越大，说明某个热点区域与某个异频段邻小区的关联性越强，从而将某个热点区域的业务分流至某个异频段邻小区的效果也越好。In a possible implementation manner, in the embodiment of the present invention, among multiple adjacent cells of different frequency bands, the first N neighboring cells of different frequency bands with the largest number of inter-frequency handovers may be determined as at least one neighboring cell of different frequency bands, where N is a positive integer. For example, N is 3, that is, the embodiment of the present invention can select 3 neighboring cells of different frequency bands as target expansion cells of different frequency bands, as shown in FIG. 4 , which takes N=3 as an example. In Fig. 4, the adjacent cells are adjacent cells in different frequency bands, and the local cell is the cell to be expanded. The greater the number of inter-frequency handovers, the stronger the correlation between a hotspot area and a neighboring cell in a different frequency band, and the better the effect of offloading services in a hotspot area to a neighboring cell in a different frequency band.
S103、根据至少一个热点区域与每个异频段邻小区的重叠覆盖度，从至少一个异频段邻小区中确定待扩容小区的异频段目标扩容小区；其中，重叠覆盖度用于指示采样点在待扩容小区的占比。S103. According to the overlapping coverage of at least one hotspot area and each different-frequency adjacent cell, determine the different-frequency target expansion cell of the cell to be expanded from at least one different-frequency adjacent cell; The proportion of the expansion area.
本发明实施例确定了待扩容小区的至少一个异频段邻小区之后，进一步地可以从至少一个异频段邻小区中确定最终的异频段目标扩容小区。In the embodiment of the present invention, after determining at least one neighboring cell of a different frequency band of the cell to be expanded, a final target expansion cell of a different frequency band may be further determined from the at least one neighboring cell of a different frequency band.
具体地，本发明实施例可以确定至少一个热点区域与每个异频段邻小区的重叠覆盖区域。可能的实施方式中，针对任一采样点，本发明实施例可以分别获取任一采样点在每个热点区域的第一参考信号接收功率(Reference Signal Receiving Power,RSRP)，以及任一采样点在每个异频段邻小区的第二RSRP，若第一RSRP与第二RSRP之间的差值位于第一预设范围内，则确定任一采样点所在区域为重叠覆盖区域，如图5所示，图5中示意了任意两个小区(A小区和B小区)的重叠覆盖区域。例如，某一采样点，在待扩容小区的RSRP为-95dBm，且在某个相邻小区的RSRP与在待扩容小区的RSRP相差在6dB以内的所有异频段邻小区为重复覆盖区域。Specifically, this embodiment of the present invention may determine the overlapping coverage area of at least one hotspot area and each adjacent cell in a different frequency band. In a possible implementation manner, for any sampling point, the embodiment of the present invention can obtain the first reference signal receiving power (Reference Signal Receiving Power, RSRP) of any sampling point in each hotspot area, and any sampling point at For the second RSRP of each adjacent cell in different frequency bands, if the difference between the first RSRP and the second RSRP is within the first preset range, it is determined that the area where any sampling point is located is an overlapping coverage area, as shown in Figure 5 , Fig. 5 shows the overlapping coverage area of any two cells (cell A and cell B). For example, at a certain sampling point, the RSRP of the cell to be expanded is -95dBm, and all adjacent cells in different frequency bands whose RSRP in a neighboring cell is within 6dB of the RSRP of the cell to be expanded are overlapping coverage areas.
其中，待扩容小区与某个异频段邻小区可能具有重复覆盖区域，也可能不具有重复覆盖区域，且待扩容小区与多个异频段邻小区的重复覆盖区域有的较大，有的较小，而如果直接将待扩容小区分流至异频段邻小区，那么就有可能将业务分流至与待扩容小区不具有重复覆盖区域，或者重复覆盖区域较小的异频段邻小区，分流效果较差。Among them, the cell to be expanded and a neighboring cell in different frequency bands may or may not have overlapping coverage areas, and the overlapping coverage areas of the cell to be expanded and multiple neighboring cells in different frequency bands may be larger or smaller. , and if the cell to be expanded is directly distributed to adjacent cells in different frequency bands, then the service may be distributed to adjacent cells in different frequency bands that do not have overlapping coverage areas with the cell to be expanded, or have smaller overlapping coverage areas, and the distribution effect is poor.
因此，本发明实施例进一步地可以根据至少一个热点区域与每个异频段邻小区的重叠覆盖度，从至少一个异频段邻小区中确定待扩容小区的异频段目标扩容小区。本发明实施例中，重叠覆盖度指的采样点在待扩容小区的占比。Therefore, the embodiment of the present invention can further determine the different-frequency-band target expansion cell of the cell to be expanded from at least one different-frequency-band neighboring cell according to the overlapping coverage of at least one hotspot area and each different-frequency-band neighboring cell. In the embodiment of the present invention, the overlapping coverage refers to the proportion of sampling points in the cell to be expanded.
具体地，本发明实施例可以根据重叠覆盖区域内的采样点在待扩容小区的占比，获得至少一个热点区域与每个异频段邻小区的重叠覆盖度，从而从至少一个异频段邻小区中选取重叠覆盖度最大的前M个异频段邻小区，作为异频段目标扩容小区，如图6所示。其中，M为正整数，例如M可以是3或者其他可能的值。图6中以热点小区为A区域为例，所确定的异频段目标扩容小区为高重叠共热点覆盖异频段邻小区，而另一个异频段邻小区(即商洛商南湘河小区)则不作为异频段目标扩容小区。Specifically, according to the embodiment of the present invention, according to the proportion of sampling points in the overlapping coverage area in the cell to be expanded, the overlapping coverage of at least one hotspot area and each adjacent cell of different frequency bands can be obtained, so as to obtain the overlapping coverage of at least one adjacent cell of different frequency bands. Select the top M adjacent cells in different frequency bands with the largest overlapping coverage as target expansion cells in different frequency bands, as shown in Figure 6. Wherein, M is a positive integer, for example, M may be 3 or other possible values. In Figure 6, the hotspot cell is the A region as an example. The determined inter-frequency band target expansion cell is a high-overlap co-hot spot coverage inter-frequency adjacent cell, while another inter-frequency adjacent cell (that is, Shangluo Shangnan Xianghe Community) is not used as an example. Different frequency band target expansion cell.
将本发明实施例提供的小区扩容小区应用于商洛地市高负荷小区扩容，通过分析统计数据发现，本发明实施例的待扩容小区扩容解决率约为88.89％，相比现有扩容方式提升60.51％，见表1。Apply the cell expansion area provided by the embodiment of the present invention to the expansion of the high-load residential area in Shangluo City. Through the analysis of statistical data, it is found that the expansion solution rate of the area to be expanded in the embodiment of the present invention is about 88.89%, which is 60.51% higher than the existing expansion method. %, see Table 1.
表1-商洛地市高负荷小区异频段扩容指标Table 1 - Expansion indicators of different frequency bands for high-load communities in Shangluo City
综上，本发明实施例中，根据待扩容小区的热点区域也就是业务量较大的区域，与待扩容小区的至少一个异频段邻小区之间的重叠覆盖度，即采样点在待扩容小区的占比，来进一步从至少一个异频段邻小区中选取待扩容小区的异频段目标扩容小区。相较于现有技术通过网络工作参数或天资采集数据来匹配异频段小区来说，本发明实施例由于是根据待扩容小区实际的热点区域与异频段邻小区的重复覆盖度来确定的，所以确定的异频段邻小区准确度较高，从而提高了扩容效果。To sum up, in the embodiment of the present invention, according to the overlapping coverage between the hotspot area of the cell to be expanded, that is, the area with a large traffic volume, and at least one adjacent cell of a different frequency band of the cell to be expanded, that is, the sampling point is in the cell to be expanded to further select a different frequency band target expansion cell of the cell to be expanded from at least one different frequency band neighboring cell. Compared with the prior art to match cells in different frequency bands by collecting data through network working parameters or talents, the embodiment of the present invention is determined according to the overlapping coverage between the actual hotspot area of the cell to be expanded and the adjacent cells in different frequency bands. The determined adjacent cells in different frequency bands have higher accuracy, thereby improving capacity expansion effect.
