Detailed Description
The embodiment of the application provides a method for evaluating coverage effectiveness of a cell, which is suitable for communication networks of different standards, wherein the communication network comprises: global System for Mobile Communications (GSM) networks, Universal Mobile Telecommunications System (UMTS) networks, Long Term Evolution (LTE) networks, fifth generation (5th generation, 5G) networks, and others in the future.
Fig. 1 shows an architectural schematic of a communication network. Each base station can only cover a small area due to limitations in base station power and spectrum resources. Therefore, in order to ensure signal coverage, operators generally divide a communication network of a large-scale area into a plurality of cells. Each cell is an area covered by one base station or a part of a base station (sector antenna). Illustratively, the communication network shown in fig. 1 is formed by cells A, B, C.
In practical applications, when an operator deploys cells, the coverage area of each cell is planned, so that it is ensured that the cells do not interfere with each other, and the communication network completely covers a predetermined area. However, with the influence of construction, optimization adjustment, antenna aging, changes in the surrounding environment of the base station, or newly-built base stations, the actual coverage area of the cell may be different from the preset coverage area, so that the coverage effectiveness of the cell is poor, thereby affecting the normal use of the UE on the communication network.
The following respectively describes the influence of two scenarios, i.e., the actual coverage area of the cell is larger than the preset coverage area and the actual coverage area of the cell is smaller than the preset coverage area, on the UE.
As shown in fig. 2, the communication network includes a cell a and a cell B. It can be seen that there is no overlap between the preset coverage area of cell a and the preset coverage area of cell B. However, when the actual coverage area of cell a is larger than the preset coverage area, cell a and cell B cover a partial area at the same time. Therefore, the UE in these areas may receive the signal of the cell a and the signal of the cell B at the same time, and the signal of the cell a and the signal of the cell B are generally in the same frequency band, so that the signal of the cell a and the signal of the cell B may interfere with each other, and the normal use of the communication network by the UE is affected.
As shown in fig. 3, the communication network includes a cell a and a cell B. It can be seen that there is no overlap between the preset coverage area of cell a and the preset coverage area of cell B. However, when the actual coverage area of cell a is smaller than the preset coverage area, there is a partial area that is not covered by any cell. Thus, the UEs located in these areas cannot access the communication network.
Therefore, it is necessary for operators to make coverage validity evaluations for cells in a communication network.
In order to accurately evaluate the coverage effectiveness of a cell, the embodiment of the present application provides a method for evaluating the coverage effectiveness of a cell, which is applied in the communication network shown in fig. 1, and the execution subject of the method is a computer device (e.g., a personal computer, a server, or a network device, etc.). As shown in fig. 4, the method includes:
101. sample data is acquired for at least one sample point in a coverage area of a communication network.
Wherein the sampling data comprises: location information, RSRP of the corresponding primary serving cell, and RSRP of the neighboring cell.
Optionally, the position information is longitude and latitude information of the sampling point.
The main service cell corresponding to the sampling point is a cell for providing service for the terminal positioned at the sampling point. It can be understood that a cell can only serve a terminal located at a sampling point when the sampling point is located in the actual coverage area of the cell.
In an alternative implementation, the sampling data of at least one sampling point in the coverage area of the communication network is obtained from drive test (or Measurement Report (MR)) data. One line of the drive test data or the MR data is recorded, which is equivalent to the sampling data of one sampling point.
102. And respectively determining the ideal coverage cells corresponding to the sampling points according to the position information of the base station corresponding to each cell, the antenna azimuth angle and the position information of each sampling point.
And the ideal coverage cell corresponding to the sampling point is a cell which is planned to cover the sampling point in each cell in advance. That is, if a certain cell is an ideal coverage cell corresponding to a sampling point, the sampling point is located in a preset coverage area of the cell.
103. And determining the coverage completion rate, the coverage distortion rate and the main service efficiency of the cell to be evaluated.
The cell to be evaluated may be any cell in the communication network.
The coverage completion rate is the ratio of the number of the first sampling points to the number of the second sampling points. The first sampling point is a sampling point which takes a cell to be evaluated as a main service cell in the second sampling points, and the second sampling point is a sampling point which takes the cell to be evaluated as an ideal coverage cell. Illustratively, sample point A, B, C is all the ideal coverage cell of cell 1, and sample point a is the primary serving cell of cell 1. In this case, sample points A, B, C are all the second sample points of cell 1, and sample point a is the first sample point of cell 1.
It will be appreciated that since the ideal coverage cell is the cell of the predetermined coverage sample, the second sample is actually the sample located within the predetermined coverage area of the cell to be evaluated. In addition, the sampling point takes the cell to be evaluated as the main serving cell, and the sampling point is shown in the actual coverage area of the cell. Therefore, the first sampling point is actually a sampling point located within the preset coverage area of the cell to be evaluated and located within the actual coverage area of the cell to be evaluated. For example, in fig. 5, sample point C, D is the second sample point of cell 1 and sample point D is the first sample point of cell 1. Therefore, the coverage completion rate can be used for evaluating the actual coverage condition of the cell to be evaluated in the preset coverage area. If the coverage completion rate of the cell to be evaluated is high, the cell to be evaluated completely covers the preset coverage area, so that the UE in the preset coverage area of the cell to be evaluated can normally use the communication network. On the contrary, if the coverage completion rate of the cell to be evaluated is low, it indicates that the cell to be evaluated does not well cover the preset coverage area, and thus the UE in the preset coverage area of the cell to be evaluated may not normally use the communication network.
The coverage distortion rate is the ratio of the number of the third sampling points to the number of the fourth sampling points. The third sampling point is a sampling point which takes the cell to be evaluated as the main service cell in the fourth sampling points, and the fourth sampling point is a sampling point which does not take the cell to be evaluated as an ideal coverage cell. Illustratively, neither sample point D, E, F covers cell 1 as ideal, and sample point D is the primary serving cell for cell 1. In this case, sample points D, E, F are all the fourth sample point for cell 1, and sample point D is the third sample point for cell 1.
It can be understood that, since the fourth sampling point is a sampling point that does not use the cell to be evaluated as an ideal coverage cell, the fourth sampling point is actually a sampling point located outside the preset coverage area of the cell to be evaluated. The third sampling point is actually a sampling point which is located outside the preset coverage area of the cell to be evaluated and is located in the actual coverage area of the cell to be evaluated. For example, in fig. 5, sample point A, B, E is the fourth sample point of cell 1, and sample point a is the third sample point of cell 1. Therefore, the coverage distortion rate can be used to evaluate the actual coverage of the cell to be evaluated outside the preset coverage area. If the coverage distortion rate is high, it indicates that the actual coverage area of the cell to be evaluated greatly exceeds the preset coverage area, so that co-channel interference exists between the cell to be evaluated and the neighboring cell thereof, and normal network use of the UE is affected.
The main service efficiency is the ratio of the number of the fifth sampling points to the number of the sixth sampling points. The fifth sampling point is a sampling point, the RSRP of the cell to be evaluated is greater than the RSRPs of other cells, and the sixth sampling point is a sampling point, the RSRP of the cell to be evaluated is greater than the first preset value, of the sampling points taking the cell to be evaluated as the main service cell.
Illustratively, the sampling point M, N, Q is a sampling point of a serving cell that is primary to the cell to be evaluated. The RSRP of a cell to be evaluated in the sampling data of the sampling point M is-65 dBm, and the maximum value of the RSRP of the adjacent cell is-75 dBm. The RSRP of a cell to be evaluated in the sampling data of the sampling point N is-76 dBm, and the maximum value of the RSRP of the adjacent cell is-102 dBm. The RSRP of the cell to be evaluated in the sampling data of the sampling point Q is-72 dBm, and the maximum value of the RSRP of the adjacent cell is-63 dBm. Assuming that the first preset value is-75 dBm, the sample point M, Q is the sixth sample point of the cell to be evaluated, and the sample point N is not the sixth sample point of the cell to be evaluated. In addition, since-65 dBm > -75dBm, sample M is the fifth sample of the cell to be evaluated. Since-72 dBm < -63dBm, sample Q is not the fifth sample for the cell being evaluated.
It can be understood that, for a sampling point using a cell to be evaluated as a main serving cell, if the RSRP of the cell to be evaluated corresponding to the sampling point is greater than a first preset value, it indicates that the sampling point meets the basic coverage requirement. On the premise that the sampling point meets the basic coverage requirement, if the RSRP of the cell to be evaluated corresponding to the sampling point is greater than the RSRP of the adjacent cells, it is indicated that the signal quality of the cell to be evaluated at the sampling point is higher than the signal quality of other adjacent cells at the sampling point, in other words, the signal quality of the cell to be evaluated at the sampling point is better. Therefore, the fifth sampling point is the sampling point with better signal quality of the cell to be evaluated, and the sixth sampling point is the sampling point which meets the basic coverage requirement in the cell to be evaluated. Thus, the primary service efficiency can be used to assess the signal quality of the cell to be assessed in the actual coverage area. Specifically, the higher the main service efficiency is, it means that the number of sampling points with better signal quality is larger in the sampling points meeting the basic coverage requirement, so that the signal quality of the cell to be evaluated in the actual coverage area is better.
104. And evaluating the coverage effectiveness of the cell to be evaluated according to the coverage completion rate, the coverage distortion rate and the main service efficiency.
Since the coverage completion rate can be used to evaluate the actual coverage condition of the cell to be evaluated in the preset coverage area, when the coverage completion rate of the cell to be evaluated is less than or equal to the third preset value, it is indicated that the cell to be evaluated cannot effectively cover the preset coverage area.
Since the coverage distortion rate can be used to evaluate the actual coverage condition of the cell to be evaluated outside the preset coverage area, when the coverage completion rate of the cell to be evaluated is greater than the fourth preset value, it indicates that the actual coverage area of the cell to be evaluated exceeds the preset coverage area.
The main service efficiency can be used for evaluating the signal quality of the cell to be evaluated in the actual coverage area, so that when the main service efficiency of the cell to be evaluated is less than or equal to a fifth preset value, the signal quality of the cell to be evaluated in the actual coverage area is poor.
It should be noted that coverage effectiveness includes both signal quality and coverage area. Therefore, the coverage effectiveness of the cell to be evaluated can be evaluated by combining the coverage completion rate, the coverage distortion rate and the main service efficiency.
Optionally, when the coverage completion rate is less than or equal to a third preset value, the coverage distortion rate is greater than a fourth preset value, or the main service efficiency is less than or equal to a fifth preset value, it may be determined that the coverage validity of the cell to be evaluated is poor. It should be noted that the third preset value, the fourth preset value, and the fifth preset value may be set according to actual situations, and the embodiment of the present application does not limit this.
For the cell with poor coverage effectiveness, the operator can send maintenance personnel to modify the cell so as to improve the coverage effectiveness of the cell.
In addition, as shown in FIG. 6, the step 102 can be implemented as the step 201-.
201. And determining a connecting line direction angle between the base station corresponding to each cell and the sampling point according to the position information of the sampling point and the position information of the base station corresponding to each cell.
And the connecting direction angle is an angle which is passed by a plane in the due north direction from clockwise rotation to the connecting plane between the base station and the sampling point.
202. And determining an included angle between the antenna azimuth angle of the base station corresponding to the cell and the connecting line direction angle according to the following formula (1).
Wherein θ represents the included angle, σ represents the connection direction angle, and γ represents an antenna azimuth angle of the base station corresponding to the cell.
Illustratively, if the azimuth angle of the antenna of the base station corresponding to the cell is 58 °, the connection direction angle between the base station corresponding to the cell and the sampling point is 72 °, and thus the included angle is 14 °.
203. When the included angle between the antenna azimuth angle of the base station corresponding to the cell and the connection line direction angle is smaller than a second preset value, determining the cell as a coverage cell corresponding to the sampling point;
optionally, the second preset value may be set according to actual conditions, for example, the second preset value is set to 90 °.
For example, the included angle between the antenna azimuth of the base station where the cell 1 is located and the connection direction angle is 60 ° (less than 90 °), so the cell 1 is a coverage cell corresponding to the sampling point.
204. And determining the distance between the sampling point and the base station corresponding to each coverage cell.
205. And determining the coverage cell corresponding to the base station closest to the sampling point as the ideal coverage cell corresponding to the sampling point.
For example, the distances between the base station A, B, C, D and the sampling points are 100m, 150m, 350m, and 75m, respectively, so that the coverage cell corresponding to the base station D is the ideal coverage cell corresponding to the sampling point.
In the embodiment of the present application, the computer device may be divided into the functional modules or the functional units according to the above method examples, for example, each functional module or functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module may be implemented in a form of hardware, or may be implemented in a form of a software functional module or a functional unit.
