Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, device, storage medium, and computer program product for determining a measurement threshold. Background Technology

[0002] With the rapid development of wireless communication technology, mobility management has become a crucial aspect of ensuring user service quality. Existing technologies primarily achieve optimal cell handover for terminals in connected states from two dimensions: measurement mechanisms and parameter configuration. On one hand, a handover triggering framework based on A1 / A2 events is constructed through a neighbor cell measurement mechanism; on the other hand, optimization strategies adapted to different network environments are designed based on the dynamic adjustment of measurement threshold parameters. These solutions provide technical support for the handover performance and user experience of wireless communication networks.

[0003] To optimize neighbor cell measurement thresholds, existing technologies mainly employ two methods: First, parameters are aligned based on the equipment manufacturer's default configuration or operator specifications. This method is only applicable to some sites and cells, and cannot achieve personalized neighbor cell configurations or accurately measure the different handover threshold requirements of all sites and cells across the entire network. Second, some neighbor cell measurement thresholds are optimized and adjusted based on drive test data, user complaints, or key network performance indicators. This method requires manual optimization analysis and targets only a small number of cells, failing to comprehensively cover all cells across the entire network.

[0004] Therefore, there is an urgent need for a method that can calculate the handover measurement threshold of all cells in the network in batches. Summary of the Invention

[0012] A measurement threshold determination device, comprising: The processor; and a memory arranged to store computer-executable instructions, which, when executed, cause the processor to perform the following operations: rasterize the acquired level data of all cell coverage sampling points to obtain at least two grids, wherein each grid includes coverage level data of at least one cell's coverage sampling points; determine a first grid set currently occupied by a target cell, and determine a set of neighboring cells corresponding to the target cell based on the first grid set; determine a handover grid corresponding to the target cell based on the coverage level data of the target cell and each neighboring cell in the set of neighboring cells, and determine a handover center level corresponding to the handover grid based on the level data of the target cell and the neighboring cells in the handover grid; and determine a start measurement threshold and a stop measurement threshold based on the handover center level.

[0013] A computer-readable storage medium storing one or more programs, which, when executed by an electronic device including multiple application programs, cause the electronic device to perform the following operations: rasterizing acquired level data of full-network cell coverage sampling points to obtain at least two grids, wherein each grid includes coverage level data of at least one cell's coverage sampling points; determining a first grid set currently occupied by a target cell, and determining a set of neighboring cells corresponding to the target cell based on the first grid set; determining a handover grid corresponding to the target cell based on the coverage level data of the target cell and each neighboring cell in the set of neighboring cells, and determining a handover center level corresponding to the handover grid based on the level data of the target cell and the neighboring cells in the handover grid; and determining a start measurement threshold and a stop measurement threshold based on the handover center level.

[0014] A computer program product includes a computer program that, when executed by a processor, performs the following: rasterization processing on acquired level data of coverage sampling points across the entire network to obtain at least two grids, wherein each grid includes coverage level data of coverage sampling points of at least one cell; determining a first grid set currently occupied by a target cell, and determining a set of neighboring cells corresponding to the target cell based on the first grid set; determining a handover grid corresponding to the target cell based on the coverage level data of the target cell and each neighboring cell in the set of neighboring cells, and determining a handover center level corresponding to the handover grid based on the level data of the target cell and the neighboring cells in the handover grid; and determining a start measurement threshold and a stop measurement threshold based on the handover center level.

[0015] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: Using the measurement threshold determination method provided in this application embodiment, when determining the measurement threshold, the level data of the obtained full network cell coverage sampling points can be rasterized to obtain at least two grids. By determining the first grid set currently occupied by the target cell, the set of adjacent cells corresponding to the target cell is determined based on the first grid set. Then, based on the coverage level data of the target cell and each adjacent cell in the set of adjacent cells, the handover grid corresponding to the target cell is determined. Based on the level data of the target cell and the adjacent cells in the handover grid, the handover center level corresponding to the handover grid is determined. Based on the handover center level, the start measurement threshold and stop measurement threshold are determined. The measurement threshold determination method provided in this application has two advantages. First, by rasterizing the level data of the entire network's cell coverage sampling points, discrete and massive measured coverage data can be transformed into structured geographic raster data. Each raster contains coverage level information of multiple cells, thus providing a unified quantitative basis for subsequent handover analysis. Furthermore, by determining the first raster set currently occupied by the target cell and its neighboring cell sets, the optimization of the handover threshold no longer relies on globally unified baseline parameters but is based on the actual neighboring cell relationships within the target cell's actual coverage area, achieving refined analysis from the cell level to the neighboring cell level. Second, by using the coverage level data of the target cell and its neighboring cells, the handover raster is determined and the handover center level is calculated. The handover raster accurately locates the area where a natural handover occurs between the target cell and its neighboring cells, and the handover center level quantitatively characterizes the relationship between the two cells within that area. The state of relatively high and consistent signal levels fully considers the actual coverage differences and signal overlap characteristics between different cell pairs, avoiding the limitations of traditional manual optimization which can only adjust a small number of cells. This ensures that the calculation results of the handover center level can truly reflect the optimal handover timing for each neighboring cell pair. Finally, the start and stop measurement thresholds are directly determined based on the handover center level. Compared with the configuration methods in existing technologies that rely on manual experience or manufacturer default parameters, this solution can automatically complete the measurement threshold optimization of all cells in the entire network in batches and automatically, significantly improving optimization efficiency and coverage. At the same time, the threshold configuration matches the actual coverage characteristics of each neighboring cell of the target cell, effectively avoiding problems such as frequent handovers, measurement interruptions, or handover failures caused by setting the threshold too early or too late, thereby improving user service perception and overall network performance.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] This application provides a measurement threshold determination method to solve the problem that existing handover measurement threshold configuration methods are only applicable to some site cells and cannot be personalized and accurately optimized based on the actual coverage differences of cells across the entire network.

[0019] The execution subject of the measurement threshold determination method provided in this application embodiment may be, but is not limited to, at least one of a measurement server, a switching server, and a communication optimization server; in addition, the execution subject of the method may also be the system or application (APP) itself running on these servers.

[0020] For ease of description, the following description uses a measurement threshold determination system as the execution subject of this method as an example to introduce its implementation. It should be understood that using a measurement threshold determination system as the execution subject is merely an illustrative example and should not be construed as a limitation of the method.

[0021] Based on the above measurement threshold determination system, the specific implementation flowchart of the measurement threshold determination method provided in this application is shown below. Figure 1 As shown, the main steps include the following: Step 11: Rasterize the obtained level data of the sampling points of the entire network cell coverage to obtain at least two grids; In this embodiment of the application, it is first necessary to collect the coverage sampling point level data of the entire network cells and neighboring cells.

[0022] In one implementation, the collected coverage sampling point level data may include, but is not limited to, the following: drive test data, frequency sweep data, measurement report (MR) data, and minimized drive test (MDT) data. In this embodiment, the measurement threshold determination system can collect, clean, and convert the level data of all cell coverage sampling points in the network through a specific data acquisition device or platform. This embodiment does not limit the specific data acquisition method, but only uses it as a basic data source.

[0023] After obtaining the level data of the sampling points of the entire network cell coverage, the measurement threshold determination system can perform rasterization processing. In this embodiment, the rasterization processing process may include: dividing the entire network area according to a grid of preset size to obtain multiple geographic grids; grouping the coverage sampling points located in the same geographic grid according to the cell, and taking the average value of the coverage level corresponding to each coverage sampling point in each cell group to obtain the coverage level data corresponding to each cell in each geographic grid.

[0024] In practical applications, the grid size can be defined according to network density or accuracy requirements (e.g., 10m × 10m or 50m × 50m). In this embodiment, the preset grid size can be set to 20m × 20m. For each grid, all sampling points falling within the geographical area of ​​that grid are determined and grouped according to cell identifiers (e.g., E-UTRAN Cell Global Identifier, ECGI). The arithmetic mean of the sampling point level values ​​within each cell group is calculated to obtain the average coverage level of that cell within that grid, in dBm. In this embodiment, after the above processing, a gridded data table as shown in Table 1 can be obtained. In Table 1, each grid stores the average coverage level of all measurable cells (including the serving cell and multiple neighboring cells) at that geographical location. Table 1. Coverage Level Data of Gridded Cells

[0025] Step 12: Determine the first set of grid cells currently occupied by the target cell, and determine the set of neighboring cells corresponding to the target cell based on the first set of grid cells; In this embodiment of the application, for the target cell to be optimized (e.g., cell A in Table 1), all the grids in which the target cell has coverage level data can be filtered out from all the grids obtained by performing step 11. These grids constitute the first grid set, which represents the actual geographical coverage of the target cell.

[0026] Then, each grid in the first grid set is traversed to determine the information of all other cells appearing in the first grid set besides the target cell. These cells are then deduplicated to form the neighboring cell set corresponding to the target cell. For example, if the target cell is cell A, cells B, C, D, etc., may appear in different grids of the first grid set; therefore, the neighboring cell set includes {B, C, D, ...}. In this way, without relying on a manually configured neighbor cell list, the measurement threshold determination system can directly extract the true neighbor cell relationships from the actual coverage data.

[0027] Step 13: Determine the handover grid corresponding to the target cell based on the coverage level data of each neighboring cell in the target cell and neighboring cell sets; In this embodiment of the application, the measurement threshold determination system can determine the handover grid in the following way: for a neighboring cell pair consisting of the target cell and any neighboring cell in the neighboring cell set, select from the first grid set the grids in which the difference between the coverage level of the target cell and the coverage level of the neighboring cell is less than a preset difference threshold, and use them as the handover grids corresponding to the target cell.

[0028] Specifically, for a target cell (let's say cell A) and one of its neighboring cells (let's say cell B), a neighboring cell pair (cell A - cell B) can be formed. Traverse all cells in the first grid set, obtaining the average coverage level of cell A and cell B within each cell. If a cell lacks data for either cell, it is skipped. Calculate the level difference between the two, i.e., |level A - level B|. When the level difference is less than a preset difference threshold, the cell is determined to be a handover zone cell for cell A - cell B.

[0029] It's important to note that in wireless communication systems, handover events are typically triggered based on the A3 event. The core logic is that the handover is triggered when the signal quality of a neighboring cell is higher than the signal quality of the current serving cell by a set offset. In the LTE network standard's handover event sequence, the A3 event is primarily used to evaluate whether there are better neighboring cells available as a handover target.

[0030] In this embodiment of the application, the triggering / cancellation conditions for the A3 event switching may include the following: A3 event triggering conditions: Mn + Ofn + Ocn - Hys>Ms + Ofs + Ocs + Off Conditions for canceling the A3 incident: Mn + Ofn + Ocn + Hys <Ms + Ofs + Ocs + Off The meanings of the parameters in the above formula are as follows: Mn: Measurement level of neighboring cells, in dB; Ofn: Specific frequency offset for neighboring cells, generally set to 0, a negative value indicates delayed handover; Ocn: Cell Individual Offset (CIO), typically set to 0; a negative value indicates delayed handover. Hys: Frequency switching hysteresis, generally set to 1; Ms: Serving cell measurement result level, in dB; Ofs: Serving cell specific frequency offset, generally set to 0; Ocs: Serving cell specific bias (CIO), typically set to 0; Off: Switch bias, usually set to 3, to prevent ping-pong switching.

[0031] It should be noted that, under normal circumstances, during natural handover, the A3 event will have a handover offset of approximately 3dB (Off) and a hysteresis of 1dB. A cumulative level difference greater than 4dB is required to trigger handover to avoid ping-pong handover. Therefore, in areas where handover is likely to occur, the level difference between the serving cell and neighboring cells is usually small. In this embodiment, the preset difference threshold can be set to 5dB, that is, grids with a level difference between the serving cell and neighboring cells within 5dB are selected as handover grids. This threshold can also be set to other values, such as 4dB or 6dB, depending on the actual network strategy.

[0032] like Figure 2 As shown in the figure, the coverage level distribution of the target cell (such as cell A) and a neighboring cell (cell B) is illustrated. Figure 2 The horizontal axis represents the geographical location, and the vertical axis represents the signal level (dBm). The left curve represents the level of the serving cell (cell A), and the right curve represents the level of the neighboring cell (cell B). The area near the intersection of the two curves (the range with a small level difference) is the approximate location of the handover grid.

[0033] After the above filtering, all handover grids between cell A and cell B are obtained, such as... Figure 3 As shown, Figure 3 The shaded areas represent grids marked as handover zones, which are concentrated in the geographical area where cell A and cell B have overlapping coverage and similar voltage levels.

[0034] Step 14: Determine the handover center level corresponding to the handover grid based on the level data of the target cell and neighboring cells in the handover grid; In this embodiment of the application, the measurement threshold determination system can determine the handover center level corresponding to the handover grid according to the following method: in the handover grid, determine the second grid position where the difference between the coverage level data of the target cell and the adjacent cell is the smallest and the coverage level data of both the target cell and the adjacent cell reach the highest value; determine the coverage level value corresponding to the second grid position as the handover center level corresponding to the handover grid.

[0035] In this embodiment of the application, the measurement threshold determination system can determine the threshold for all handover band grid sets G of neighboring cell pairs (cell A - cell B). AB Calculate the cell A level Rs within each grid i. Ai and cell B level Rs Bi Then, we search for the raster index k that satisfies the following conditions: Condition 1: |Rs Ak -Rs Bk | In set G AB The smallest value in the middle, meaning the closest voltage level; Condition 2: Rs Ak and Rs Bk Choose the largest possible value, typically selecting the grid that maximizes the sum of the two values ​​among multiple grids that satisfy condition 1, or the grid that maximizes the higher of the two values.

[0036] At the optimal grid k, the level values ​​of cell A and cell B, or their average, are determined as the handover center level. Since the levels of the two cells are close within the handover band, the average of the two levels can be directly taken as the handover center level according to the following formula [1]: [1] in, and This represents the total computing power and total memory capacity of the node. and It is time-varying, representing the remaining available resources at a given time, which is a key constraint on resource allocation. These are the geographic coordinates of the node, used to calculate the distance to the mobile terminal.

[0037] A L Used to describe the transmission capacity and latency characteristics of each physical link, for each physical link Connect two nodes Its attributes are defined as shown in the following formula [2]: [2] Alternatively, the switching center level can be defined as the larger or smaller of the two levels, which can be adjusted according to the network strategy. This embodiment preferably uses the average value to represent the signal level at the switching point in a balanced way.

[0038] Repeat the above process for each neighbor cell pair of the target cell to obtain the handover center level of all neighbor cell pairs in the entire network, as shown in Table 2: Table 2. Neighbor cell relationships and handover center level tables for all cells in the network.

[0039] Step 15: Determine the start measurement threshold and stop measurement threshold based on the switching center level obtained by performing step 14.

[0040] In this embodiment, the measurement threshold determination system can determine the start and stop measurement thresholds according to the following method: First, the target cell and any adjacent cell in the adjacent cell set are grouped according to frequency points to obtain frequency point groups; then, for each frequency point group, the maximum value of the handover center level of each adjacent cell pair in the frequency point group is determined as the natural handover level value of the target cell in the corresponding frequency point group; finally, the start and stop measurement thresholds are determined according to the natural handover level value and the network coverage occupancy policy corresponding to the frequency point group.

[0041] Specifically, assuming the target cell-cell C operates at frequency point 1, all its neighboring cells may be distributed at different frequency points, such as frequency point 1, frequency point 2, frequency point 3, frequency point 4, etc. All neighboring cell pairs are grouped according to the frequency points to which the neighboring cells belong. For each frequency point group, according to the following formula [2], the handover center level of all neighboring cell pairs in the group is taken, and the maximum value among them is taken as the natural handover level value of the target cell at that neighboring cell frequency point: [2] Where f represents a frequency point of a neighboring cell, and C is the target cell.

[0042] Next, the final handover measurement threshold is determined according to the network coverage occupancy policy. In this embodiment, the measurement threshold determination system can determine the final handover measurement threshold in the following way: determining the frequency offset value corresponding to the frequency point group according to the network coverage occupancy policy; determining the actual handover level according to the natural handover level value and the frequency offset value; and setting the start measurement threshold and the stop measurement threshold according to the preset offset based on the actual handover level.

[0043] In this application embodiment, the network coverage occupancy strategy includes the same frequency strategy, the different frequency strategy, and the frequency offset setting strategy.

[0044] The frequency offset value is used to adjust the relative speed of handover: a positive frequency offset causes the handover to occur earlier, while a negative frequency offset causes the handover to occur later. Typically, the frequency offset for neighboring cells on the same frequency is set to 0dB; for neighboring cells on different frequencies, a positive or negative frequency offset value can be set according to the operator's needs, for example, a frequency offset of +6dB is used for early handover, and a frequency offset of -6dB is used for delayed handover.

[0045] After obtaining the actual switching level, the measurement start threshold and measurement stop threshold can be determined. According to the general configuration of the communication system, the measurement start threshold is usually set 3dB higher than the actual switching level, and the measurement stop threshold is 3dB higher than the measurement start threshold.

[0046] It should be noted that the 3dB offset mentioned above is only an example. In actual systems, it can be adaptively adjusted according to switching parameters (such as hysteresis Hys, offset Off, etc.). For example, in the embodiments of this application, the threshold can be calculated according to the offset shown in Table 3: Table 3 Calculation table for switching measurement thresholds at each frequency point

[0047] For example, for neighboring cell C at frequency point 3, the maximum handover center level is -96dBm. Using an early handover strategy with a frequency offset δ = +6dB, the actual handover level is -96 + 6 = -90dBm. Therefore, the detection threshold is -90 + 3 = -87dBm, and the shutdown threshold is -87 + 3 = -84dBm (or -90 + 6 = -84dBm). As another example, for neighboring cell C at frequency point 4, under a delayed handover strategy with δ = -6dB, the actual handover level is -99 - 6 = -105dBm, the detection threshold is -105 + 3 = -102dBm, and the shutdown threshold is -102 + 3 = -99dBm.

[0048] By following the steps above, precise measurement start and stop thresholds can be determined for target cell C at different neighboring cell frequencies. These threshold values ​​can be directly configured in network equipment to control when user equipment (UE) starts measuring inter-frequency / inter-system neighboring cells and when it stops measuring, thereby minimizing service interruptions caused by measurements while ensuring handover success rate and improving user experience.

[0049] Using the measurement threshold determination method provided in this application embodiment, when determining the measurement threshold, the level data of the obtained full network cell coverage sampling points can be rasterized to obtain at least two grids. By determining the first grid set currently occupied by the target cell, the set of adjacent cells corresponding to the target cell is determined based on the first grid set. Then, based on the coverage level data of the target cell and each adjacent cell in the set of adjacent cells, the handover grid corresponding to the target cell is determined. Based on the level data of the target cell and the adjacent cells in the handover grid, the handover center level corresponding to the handover grid is determined. Based on the handover center level, the start measurement threshold and stop measurement threshold are determined. The measurement threshold determination method provided in this application has two advantages. First, by rasterizing the level data of the entire network's cell coverage sampling points, discrete and massive measured coverage data can be transformed into structured geographic raster data.

The handover raster accurately locates the area where a natural handover occurs between the target cell and its neighboring cells, and the handover center level quantitatively characterizes the relationship between the two cells within that area. The state of relatively high and consistent signal levels fully considers the actual coverage differences and signal overlap characteristics between different cell pairs, avoiding the limitations of traditional manual optimization which can only adjust a small number of cells. This ensures that the calculation results of the handover center level can truly reflect the optimal handover timing for each neighboring cell pair. Finally, the start and stop measurement thresholds are directly determined based on the handover center level. Compared with the configuration methods in existing technologies that rely on manual experience or manufacturer default parameters, this solution can automatically complete the measurement threshold optimization of all cells in the entire network in batches and automatically, significantly improving optimization efficiency and coverage. At the same time, the threshold configuration matches the actual coverage characteristics of each neighboring cell of the target cell, effectively avoiding problems such as frequent handovers, measurement interruptions, or handover failures caused by setting the threshold too early or too late, thereby improving user service perception and overall network performance.

[0050] In one embodiment, this application also provides a measurement threshold determination device to address the problem that existing handover measurement threshold configuration methods are only applicable to some site cells and cannot perform personalized and precise optimization based on the actual coverage differences of all cells in the network. A schematic diagram of the specific structure of the measurement threshold determination device is shown below. Figure 4As shown, it includes: a gridding unit 41, a neighboring cell determination unit 42, a handover level determination unit 43, and a measurement threshold determination unit 44.

[0051] The rasterization unit 41 is used to rasterize the acquired level data of the full network cell coverage sampling points to obtain at least two grids, wherein each grid includes the coverage level data of at least one cell coverage sampling point. The neighboring cell determination unit 42 is used to determine the first grid set currently occupied by the target cell, and to determine the neighboring cell set corresponding to the target cell based on the first grid set; The handover level determination unit 43 is used to determine the handover grid corresponding to the target cell based on the coverage level data of the target cell and each neighboring cell in the neighboring cell set, and to determine the handover center level corresponding to the handover grid based on the level data of the target cell and the neighboring cells in the handover grid. The measurement threshold determination unit 44 is used to determine the start measurement threshold and stop measurement threshold based on the switching center level.

[0052] In one embodiment, the rasterization unit 41 is specifically used to divide the entire network area according to a grid of preset size to obtain multiple geographic grids; group the coverage sampling points located in the same geographic grid according to cells, and take the average value of the coverage power corresponding to each coverage sampling point in each cell group to obtain the coverage level data corresponding to each cell in each geographic grid.

[0053] In one embodiment, the handover level determination unit 43 is specifically used to select, from the first grid set, grids in which the difference between the coverage level of the target cell and the coverage level of the neighboring cell is less than a preset difference threshold for a neighboring cell pair formed by the target cell and any neighboring cell in the neighboring cell set, and use them as the handover grids corresponding to the target cell.

[0054] In one embodiment, the handover level determination unit 43 is specifically used to determine, within the handover grid, a second grid position where the difference in coverage level data between the target cell and the adjacent cell is the smallest, and the coverage level data of both the target cell and the adjacent cell reaches the highest value; and to determine the coverage level value corresponding to the second grid position as the handover center level corresponding to the handover grid.

[0056] In one embodiment, the measurement threshold determination unit 44 is specifically used for: determining the frequency offset value corresponding to the frequency point group according to the network coverage occupancy strategy; determining the actual switching level according to the natural switching level value and the frequency offset value; and setting the start measurement threshold and the stop measurement threshold according to the actual switching level as a reference and a preset offset, respectively.

[0057] Using the measurement threshold determination device provided in this application embodiment, when determining the measurement threshold, the acquired level data of the full network cell coverage sampling points can be rasterized to obtain at least two grids. By determining the first grid set currently occupied by the target cell, the set of adjacent cells corresponding to the target cell is determined based on the first grid set. Then, based on the coverage level data of the target cell and each adjacent cell in the set of adjacent cells, the handover grid corresponding to the target cell is determined.

Finally, the start and stop measurement thresholds are directly determined based on the handover center level. Compared with the configuration methods in existing technologies that rely on manual experience or manufacturer default parameters, this solution can automatically complete the measurement threshold optimization of all cells in the entire network in batches and automatically, significantly improving optimization efficiency and coverage. At the same time, the threshold configuration matches the actual coverage characteristics of each neighboring cell of the target cell, effectively avoiding problems such as frequent handovers, measurement interruptions, or handover failures caused by setting the threshold too early or too late, thereby improving user service perception and overall network performance.
