[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0054] Figure 1 A flowchart illustrating the communication quality analysis method provided by this invention is shown below. Figure 1 As shown, the method includes:

[0055] Step 110: Obtain the wireless utilization rate, MR coverage rate, and 5G terminal dwell times of the target cell.

[0056] Specifically, the target cell is the cell that requires communication quality analysis. For example, the target cell could be a rural area, a town, or a cell where 5G sites have not yet been planned and where the same sector does not contain the D frequency band.

[0057] Wireless utilization rate refers to the utilization rate of a cell's wireless network resources, which can be determined by the average utilization rate of PRBs (Physical Resource Blocks). This indicator is the ratio of the number of PRBs actually used in the physical channels of an eNodeB (Evolved Node B, a base station in LTE) to the number of available PRBs in the cell's physical channels within a statistical period.

[0058] MR (Measurement Report) coverage is used to assess the quality of the wireless environment. It can be used to render uplink and downlink signal strength distribution, revealing weak or dead zones in network coverage and enabling the timely detection of network coverage problems. For example, cell MR coverage can be defined as the ratio of the number of MR sampling points with signal strength less than -110 dBm to the total number of MR sampling points.

[0059] The 5G terminal dwell count refers to the number of times a terminal supporting the 5G network standard attaches to a cell. It can be used to assess the 5G network requirements of a target cell.

[0060] Step 120: Based on wireless utilization, MR coverage, and 5G terminal dwell times, determine the evaluation results of the target cell in multiple communication quality analysis dimensions; among which, the communication quality analysis dimensions include capacity enhancement dimension, coverage enhancement dimension, and NR evolution dimension.

[0061] Specifically, multiple communication quality analysis dimensions can be set, such as capacity enhancement, coverage enhancement, and NR evolution. The communication quality of the target cell can be evaluated from multiple dimensions.

[0062] The evaluation results for the capacity enhancement dimension are used to measure whether the network capacity of the target cell meets the network requirements of the cell. The evaluation results for the coverage enhancement dimension are used to measure whether the network coverage of the target cell meets the network requirements of the cell. The evaluation results for the NR (New Radio) evolution dimension are used to measure whether the target cell has the 5G network service requirement.

[0063] Step 130: Analyze the communication quality of the target cell based on the evaluation results of the target cell in multiple communication quality analysis dimensions.

[0064] Specifically, the communication quality of a target cell can be analyzed based on the evaluation results of the target cell across multiple communication quality analysis dimensions. For example, based on the evaluation results of the target cell in the capacity enhancement dimension, it can be determined whether the network capacity of the target cell should be enhanced; based on the evaluation results of the target cell in the coverage enhancement dimension, it can be determined whether the network coverage of the target cell should be enhanced; and based on the evaluation results of the target cell in the NR evolution dimension, it can be determined whether 5G network should be deployed in the target cell.

[0065] The communication quality analysis method provided in this invention evaluates the communication quality of a target cell from the dimensions of capacity enhancement, coverage enhancement, and NR evolution by using the target cell's radio utilization, MR coverage, and 5G terminal dwell times. Furthermore, it analyzes the communication quality of the target cell based on the evaluation results. This eliminates the need for manual experience-based judgment and enables batch analysis of the communication quality of multiple cells, thereby improving the accuracy and efficiency of the communication quality analysis results.

[0066] Based on the above embodiments, step 120 includes:

[0067] Based on wireless utilization and the capacity enhancement evaluation function, the capacity enhancement dimension evaluation results of the target cell are determined.

[0068] Based on MR coverage rate and coverage enhancement evaluation function, the coverage enhancement dimension evaluation results of the target cell are determined;

[0069] Based on the number of times the 5G terminal stays and the NR evolution evaluation function, the NR evolution dimension evaluation results of the target cell are determined.

[0070] The capacity enhancement evaluation function is determined based on the radio utilization of multiple sample target cells and the capacity enhancement dimension evaluation results of each sample target cell.

[0071] The coverage enhancement evaluation function is determined based on the MR coverage of multiple sample target cells and the coverage enhancement dimension evaluation results of each sample target cell;

[0072] The NR evolution evaluation function is determined based on the number of 5G terminal visits in multiple sample target cells and the NR evolution dimension evaluation results of each sample target cell.

[0073] Specifically, based on data from multiple sample target cells, capacity enhancement evaluation functions, coverage enhancement evaluation functions, and NR evolution evaluation functions can be established. These functions are used to calculate the radio utilization rate, MR coverage rate, and 5G terminal dwell times collected from the target cells, yielding evaluation results for the capacity enhancement dimension, coverage enhancement dimension, and NR evolution dimension. The sample target cells here are those that have undergone communication quality analysis, and whose base station equipment has been upgraded based on the analysis results, resulting in improved communication quality.

[0074] First, we can obtain the radio utilization rate, MR coverage rate, and 5G terminal dwell times of multiple sample target cells. Specifically, the LTE radio utilization rate is obtained by aggregating hourly metrics from 15 minutes of performance data collected via the northbound interface, and the maximum value of the hourly metrics over 7 days is taken. The MR coverage rate is obtained by aggregating daily data from the MRO (Measure Report Original) server, and the average of the daily metrics over 7 days is taken. The 5G terminal dwell times are obtained by aggregating daily data from the SEQ (Service Experience Quality) server, and the average of the daily metrics over 15 days is taken. Explanations of each metric are shown in Table 1.

[0075] Table 1 Indicator Explanation

[0076]

[0077] Among them, CCE (Channel Control Element) is the resource unit for channel resource allocation.

[0078] After acquiring the data of the target sample cells, based on the future development trend of mobile networks, capacity enhancement and coverage enhancement assessments are prioritized for the target sample cells, followed by NR evolution assessments, to obtain the capacity enhancement dimension assessment results, coverage enhancement dimension assessment results, and NR evolution dimension assessment results for each target sample cell.

[0079] The specific evaluation rules are shown in Table 2.

[0080] Table 2 Evaluation Rules

[0081]

[0082] Based on the evaluation results of the target cells in the above samples, a scatter plot was constructed using the data, and after fitting, the capacity enhancement evaluation function, coverage enhancement evaluation function, and NR evolution evaluation function were obtained. In particular, when fitting the NR evolution evaluation function, a quadratic nonlinear scoring function can be constructed to avoid the concentration of linear function scores.

[0083] The following examples illustrate this. Figure 2 Fitting curves of the capacity enhancement evaluation function and coverage enhancement evaluation function provided by this invention are shown below. Figure 2 As shown, the capacity enhancement evaluation function f r (x) is:

[0084]

[0085] In the formula, x represents the LTE radio utilization rate during the cell's busy period.

[0086] Coverage enhancement evaluation function f g (y) is:

[0087]

[0088] In the formula, y represents the MR coverage rate of the cell.

[0089] Capacity enhancement scoring function f r (x) is positively correlated with the value of x, and the coverage enhancement scoring function f g (y) is negatively correlated with the y value. The slopes of the two functions are the same in the middle part, and the function values ​​correspond to each other after inputting the remaining values. This makes it convenient to evaluate the function values ​​from two dimensions to compare the communication quality assessment and analysis scheme.

[0090] Figure 3 The fitting curve of the NR evolution evaluation function provided by this invention is shown below. Figure 3 As shown, the NR evolution evaluation function f n (z) is:

[0091]

[0092] In the formula, z represents the number of times the 5G terminal stays in the cell.

[0093] NR evolution evaluation function f n (z) is logarithmically positively correlated with the z value; the more times the 5G terminal stays, the higher the necessity of NR evolution, which is in line with expectations. Based on the fitted capacity enhancement evaluation function, coverage enhancement evaluation function, and NR evolution evaluation function, the communication quality of the target cell can be evaluated.

[0094] The communication quality analysis method provided in this invention, compared with the existing manual assessment of target cells, analyzes and models relevant indicators to construct a communication quality assessment function, thereby achieving rapid and accurate assessment of the communication quality of target cells and providing support and basis for subsequently determining improvement schemes for the communication quality of target cells.

[0095] Based on any of the above embodiments, step 130 includes:

[0096] If the assessment results for capacity enhancement, coverage enhancement, and NR evolution are all zero, then the target cell is determined to have no communication quality improvement requirement. If the capacity enhancement assessment result is zero and the coverage enhancement assessment result is not zero, or the coverage ratio is less than the first coverage ratio setting, then the target cell's communication quality improvement requirement is coverage enhancement. If the capacity enhancement assessment result is not zero and the coverage enhancement assessment result is zero, or the coverage ratio is greater than the second coverage ratio setting, then the target cell's communication quality improvement requirement is capacity enhancement. If the coverage ratio is greater than the first coverage ratio setting and less than the second coverage ratio setting, then the target cell's communication quality improvement requirement is simultaneous coverage and capacity enhancement. If the capacity enhancement and coverage enhancement assessment results are both zero, and the NR evolution assessment result is greater than the NR evolution setting, then the target cell's communication quality improvement requirement is NR evolution. The coverage ratio of the target cell is determined based on the capacity enhancement and coverage enhancement assessment results.

[0097] Specifically, when the capacity enhancement evaluation function f r (x) and the coverage enhancement evaluation function f g When (y) are all non-zero, the coverage ratio f can be defined. b (x,y) is:

[0098] f b (x,y)=f r (x) / f g (y)

[0099] Figure 4 The fitting curve of the coverage ratio provided by the present invention, such as Figure 4 As shown, when the cell's LTE radio utilization x and MR coverage y have the same value, the coverage ratio f b The global domain of the function (x, y) is: tending to This indicates that the score for the cell capacity dimension is much lower than the score for the coverage dimension. b (x,y) approaching 1 indicates that the cell capacity dimension score and the coverage dimension score are similar, f b The fact that (x,y) approaches infinity indicates that the cell capacity score is much higher than the coverage score. This function can be used to determine f. r (x) function and f g (y) represents the relative magnitude of the function value.

[0100] The communication quality improvement requirements of the target cell refer to the wireless network improvement requirements of the target cell, which may include capacity enhancement, coverage enhancement, simultaneous capacity and coverage enhancement, and NR evolution.

[0101] If the assessment results for capacity enhancement, coverage enhancement, and NR evolution are all zero, it is determined that the target cell has no need for communication quality improvement. In other words, the communication quality of the target cell can meet the network needs of users within the cell, and no further improvement is required.

[0102] If the capacity enhancement dimension assessment result is zero and the coverage enhancement dimension assessment result is not zero, or if the coverage ratio is less than the first coverage ratio setting value, then the communication quality improvement requirement for the target cell is determined to be coverage enhancement. This means that the network coverage of the target cell cannot meet the network needs of users within the cell, and network coverage enhancement is required. The first coverage ratio setting value can be set according to the actual situation.

[0103] If the capacity enhancement dimension assessment result is not zero and the coverage enhancement dimension assessment result is zero, or if the coverage ratio is greater than the second coverage ratio setting value, then the communication quality improvement requirement for the target cell is determined to be capacity enhancement. This means that the network capacity of the target cell cannot meet the network needs of users within the cell, and network capacity enhancement is required. The second coverage ratio setting value can be set according to the actual situation.

[0104] If the coverage ratio is greater than the first coverage ratio setting value and less than the second coverage ratio setting value, then the communication quality improvement requirement of the target cell is determined to be simultaneous enhancement of coverage and capacity. That is, the network capacity and network coverage of the target cell cannot meet the network needs of users in the cell, and simultaneous enhancement of both network capacity and network coverage is required.

[0105] If both the capacity enhancement dimension assessment result and the coverage enhancement dimension assessment result are zero, and the NR evolution dimension assessment result is greater than the NR evolution dimension setting value, then the communication quality improvement requirement of the target cell is determined to be NR evolution. That is, the network services of the target cell cannot meet the network needs of users in the cell, and 5G network services need to be activated.

[0106] The results of the above analysis can be represented in Table 3.

[0107] Table 3. Analysis of Communication Quality Improvement Needs

[0108]

[0109]

[0110] Based on any of the above embodiments, step 130 is followed by:

[0111] Based on the TA user distribution of the target cell, determine the type of the target cell;

[0112] Based on the type of the target cell and the communication quality improvement requirements of the target cell, the communication quality of the target cell is improved.

[0113] The target cell types include near-end user cells and far-end user cells.

[0114] Specifically, by sampling the Time Advanced (TA) in the target cell, the TA user distribution of the target cell can be obtained. The TA user distribution is used to represent the distance between the user terminal and the base station.

[0115] For a target cell, if the proportion of TA sampling points less than 500 meters away from the base station in the MR of the target cell is greater than 50% of all TA sampling points, the target cell can be determined as a near-end user cell. If the proportion of TA sampling points greater than 1000 meters away from the base station in the MR of the target cell is greater than 50% of all TA sampling points, the target cell can be determined as a far-end user cell.

[0116] Based on any of the above embodiments, and based on the type of the target cell and the communication quality improvement requirements of the target cell, the communication quality of the target cell is improved, including:

[0117] If the target cell's communication quality improvement requirement is capacity enhancement, then the existing frequency band of the target cell will be expanded; if the target cell is a remote user cell and the communication quality improvement requirement is coverage enhancement, then an 8T16R antenna will be used for the target cell; if the target cell is a near-end user cell and the communication quality improvement requirement is simultaneous coverage and capacity enhancement, then a six-sector inter-frequency soft split will be used for the target cell; if the target cell is a remote user cell and the communication quality improvement requirement is simultaneous coverage and capacity enhancement, then the existing frequency band of the target cell will be expanded and an 8T16R antenna will be used; if the target cell's communication quality improvement requirement is NR evolution, then 5G network coverage will be enabled in the existing frequency band of the target cell.

[0118] Specifically, for the target cell, there are four communication quality improvement schemes, each with different applicable scopes, as shown in Table 4. Existing technologies, when using these schemes, cannot quickly identify and accurately match them in batches, resulting in low efficiency in communication quality improvement.

[0119] The method provided in this invention can quickly determine a communication quality improvement scheme based on the type of the target cell and the communication quality improvement requirements of the target cell, and improve the communication quality of the target cell.

[0120] Table 4 Scope of Application for Communication Quality Improvement Schemes

[0121]

[0122] If the target cell's communication quality improvement requirement is capacity enhancement, then the existing frequency band of the target cell will be expanded. If the target cell is a remote user cell and the communication quality improvement requirement is coverage enhancement, then an 8T (Transmit) 16R (Receive) antenna will be used for the target cell. If the target cell is a near-end user cell and the communication quality improvement requirement is simultaneous coverage and capacity enhancement, then a six-sector inter-frequency soft split will be used for the target cell. If the target cell is a remote user cell and the communication quality improvement requirement is simultaneous coverage and capacity enhancement, then the existing frequency band of the target cell will be expanded and an 8T 16R antenna will be used. If the target cell's communication quality improvement requirement is NR evolution, then 5G network coverage will be enabled in the existing frequency band of the target cell. The above methods can be represented by Table 5.

[0123] Table 5. Methods for Determining Communication Quality Improvement Schemes

[0124]

[0125]

[0126] Based on any of the above embodiments, step 110 includes:

[0127] Based on the set collection period, the wireless utilization rate, MR coverage rate, and 5G terminal dwell times of the target cell are obtained.

[0128] Specifically, different collection cycles can be set for the wireless utilization rate, MR coverage rate, and 5G terminal dwell times of the target cell, depending on the actual situation.

[0129] For example, the collection period can be set to 7 days for wireless utilization; 7 days for MR coverage; and 15 days for 5G terminal dwell times.

[0130] Based on any of the above embodiments Figure 5 This is a flowchart illustrating the implementation of the D-band equipment reuse scheme according to an embodiment of the present invention. Figure 5 As shown, a periodic evaluation method can be used to assess the communication quality of the target cell, thereby improving communication quality using existing equipment. The evaluation period can be monthly or weekly.

[0131] To enable the rapid and large-scale implementation of D-band equipment reuse, the rules for reusing and inventorying D-band equipment should be normalized to maximize the utilization of existing network resources.

[0132] First, determine the communication quality improvement plan and conduct an inventory of reusable equipment. Implement the plan based on the inventory results, as shown in Table 6.
