Description
Technical Field
The invention relates to a checking technology, in particular to a method and a device for checking full-network station work parameters based on periodic measurement data.
Background
For checking station parameters in an LTE network, the prior art mainly includes the following schemes:
the existing scheme 1: the station worker parameter check is carried out through manual on-site station arrival, longitude and latitude and azimuth checking through a GPS and a level meter, and the like, so that whether the worker parameter of the station has errors can be directly found. The problems with this solution are: due to manual operation, the workload of the whole network inspection is large, only partial sites can be actually checked, the whole network employee parameter inspection cannot be performed in a normalized mode, and the daily optimization work of the LTE network optimization cannot be supported efficiently.
Existing scheme 2: and (3) carrying out site engineering parameter checking by adopting an Automatic neighbor cell optimization (ANR) technology. The ANR function is that a terminal measures a wireless signal and reports a cell with the best level to a network side as a neighbor cell reference cell. By comparing the neighbor cell reported by the ANR function with the neighbor cell calculated according to the GIS coordinate, if the matching degree is lower than a certain threshold, the station parameter of the LTE cell can be found to have an error. The problems with this solution are: ANR is a terminal selectable function, most terminals of the existing network do not support the ANR function, and reported ANR neighbor cells cannot reflect the problem of the whole network. In addition, the ANR function requires the terminal to measure all the time, which increases the power consumption of the terminal and reduces the standby time of the terminal.
Existing scheme 3: the azimuth angle is judged based on periodic measurement data such as signal transmission time delay (TA) reported by MRO and signal arrival angle (AOA), and if the AOA exceeds a certain range, the station working parameter of the LTE cell is found to be wrong. The problems with this solution are: on one hand, in a main urban area, buildings are dense, signal reflection and diffraction environments are rich, and TA + AOA cannot really reflect the position relation between UE and eNodeB. On the other hand, the AOA needs to start beamforming on the network side to perform measurement, but the LTE network only uses beamforming technology for TM7 and TM8, and for UEs in other TM modes, there is no AOA measurement amount, which may cause that part of UEs cannot participate in evaluation, and the evaluation accuracy is reduced.
Existing scheme 4: and calculating the association degree of the base station based on the switching times, and if the switching frequency sequence is not matched with the association degree of the GIS, judging that the cell parameter is wrong. The problems with this solution are: the switching frequency depends on the relationship of the configured adjacent cells, and the adjacent cell relationship has the problems of missing and mismatching, so that the judgment accuracy is reduced.

The embodiment of the invention is explained by taking a practical application scene as an example as follows:
in an application scenario applying the embodiment of the present invention, a site parameter checking scheme for calculating a base station association degree based on periodic measurement data is specifically provided. Here, the periodic measurement data includes MRO and MRS files. The site working parameter checking scheme of the application scene comprises the following steps: and determining neighboring cells with real strong correlation with the neighboring cells by analyzing MRO data of the LTE cell of the whole network, and deducing whether the neighboring cells with the real strong correlation can be correlated in theory according to the working parameters provided by the base station working parameter base. If the real strong association of a certain cell but the occupation ratio of the adjacent cell without the strong association theoretically exceeds the preset threshold, the situation that an error exists between the value of the station working parameter of the cell in the working parameter library and the actual working parameter can be judged, and therefore the station working parameter checking work of the whole network LTE station can be efficiently finished.
The application scene adopts the embodiment of the invention, and can solve the following problems:
1. the embodiment of the invention can realize the regular checking of the working parameters of the whole network and ensure that the checking of the working parameter accuracy of the whole network enters into normalization.
2. The MRO reporting is a necessary function of the terminal, does not need the special function support of the terminal, is irrelevant to the transmission mode of the base station, and can utilize the reported data of the terminal of the whole network to improve the positioning precision.
3. By adopting the embodiment of the invention, the relevance is calculated only based on the RSRP of the MRO, and the method and the device are suitable for all transmission modes and all coverage scenes.
4. And calculating according to the actually reported RSRP of the terminal, and being irrelevant to the configuration of the adjacent cell relation.
5. The accuracy of the working parameter is improved without making any prior assumption and depending on the current network parameter configuration.
The application scene one:
as shown in fig. 2, the process of determining whether there is an error between the value in the parameter library of a single cell and the actual parameter includes:
step 201, judging whether the current cell is an effective cell. If the number of MRO sampling points of the cell is less than 500, the integrity of the current MRO data of the current cell can be approximately considered to have a problem, and the current MRO data is not put into the calculation. If the number of MRO sampling points > is 500, the current MRO data acquisition of the cell can be considered to have integrity, and the accuracy of the working parameters of the cell can be judged based on the current MRO data.
Step 202: and determining the actual strong correlation adjacent cell of the target cell through the MRO data. And taking the target cell as a service cell and taking the peripheral cells as adjacent cells. And if the MRO sampling point number of the main RSRP-adjacent RSRP of one peripheral cell within the absolute value of 6db accounts for the total MRO sampling point number ratio of this time > is 10%, the peripheral cell is considered to be an actual strong-association adjacent cell of the target cell, and the step 203 is executed, otherwise, the peripheral cell is not the actual strong-association adjacent cell of the target cell and does not contribute to the rationality judgment.
Step 203: and forming a candidate cell set by the actual strong correlation adjacent cells of the target cell, and if the candidate cell set is an empty set, namely, the periphery of the target cell has no actual strong correlation adjacent cells, ending the correlation analysis of the target cell.
Step 204: for co-sited co-directional cells in the candidate cells, only one of the cells is reserved for subsequent calculation, so that the weight of each work parameter vector (longitude, latitude, station height, and downward inclination) of the candidate cell set is 1.
Here, the method for determining the co-sited co-directional coverage cell includes: if the two cells meet the following two conditions, the 2 cells are judged to be co-sited and co-directional coverage cells.
The first condition is as follows: distance judgment: the distance between two cells is less than 50 m
And a second condition: and (4) MRO data judgment: in MRO data, if the ratio of the absolute value of the primary serving cell RSRP to the neighboring cell RSRP of two cells in the same frequency band is less than 6db > is 80%, the ratio of the absolute value of the primary serving cell RSRP to the neighboring cell RSRP of two cells in different frequency bands is less than 10db > is 80%.
Step 205: to speed up the calculation, the candidate cell set may be sorted from high to low according to the sampling point ratio, then the top N (N > -6) cells are taken to participate in the subsequent calculation, and if the number of cells in the result of step4 is less than N, all cells are taken to participate in the subsequent calculation.
Step 206: and deducing whether the cell obtained by step4 has theoretical correlation according to the working parameters of the working parameter library, and marking the target cell as an error to the adjacent cell if the cell is actually correlated but not theoretically correlated.
Step 207, whether the error rate reaches a threshold or not, if not, the target cell parameter is accurate; otherwise, if the value exceeds the threshold, an error exists between the value of the station parameter of the target cell in the base station parameter database and the actual value of the station parameter.
Here, specifically: and calculating a cell error rate which is (the number of distance error cells + the number of angle error cells)/(the number of distance error cells + the number of angle correct cells), and if the cell error rate exceeds a preset threshold, judging that the working parameters of the cell in the working parameter library have errors.
Application scenario two: whether the cells with the results of the working parameter derivation step 204 according to the working parameter library have theoretically relevant relevance calculation process is realized, and the following steps are included:
firstly, distance judgment:
fig. 3 is a schematic diagram showing the theoretical relationship among the vertical lobe angle, the downtilt angle, the station height, and the coverage distance of a cell, where S, H, α, and β are the upper side lobe coverage distance, the station height, the downtilt angle, and the vertical lobe angle of a target cell, respectively, and if H, α, and β are known, H is obtained
S can be obtained according to the station height, the downward inclination angle and the azimuth angle of a target cell in the working parameter library, and the distance d between the target cell and each peripheral strong adjacent cell is obtained according to the longitude and latitude in the working parameter libraryiN, if a certain di>And S, marking the association relation from the target cell to the cell as distance error, otherwise, marking the association relation as distance correct, and entering the cell marked as distance correct into azimuth judgment.
II, azimuth angle judgment:
and judging the angle accuracy of the cell marked as accurate distance, if the cell marked as accurate distance is judged to be not associated, marking that the association relation from the target cell to the cell is an angle error, otherwise marking that the angle is correct. The specific algorithm for the angle determination is set forth below.
The horizontal coverage area of the directional antenna can be divided into 4 areas as shown in fig. 4, where area 1 is the main lobe coverage area of the base station, areas 2 and 4 are the side coverage areas of the base station, and area 3 is the back coverage area of the base station.
