Description
Technical Field
The invention relates to the technical field of wireless communication, in particular to a method, a device, equipment and a storage medium for determining a building 5G coverage construction scheme.
Background
In the age of 5G revolution, the development of 5G networks enables the industry of Internet of things to emerge more innovative solutions. More services are made possible. The intelligent building market presents the blowout situation, and intelligent building becomes more high-efficient, the accurate, the low consumption environmental protection of management, demonstrates very big interactivity of serving because of the joining of 5G.
The existing building coverage construction scheme determination method is mainly used for evaluating the 5G signal coverage condition in a building through 5G simulation software, a building test traversal method or a 5G MR positioning mode. The 5G simulation software evaluates the coverage condition of 5G signals in the building, and the coverage condition in the building is finally calculated mainly by combining base station parameters (including information such as base station position, height and power parameters), link budget (signal loss and gain on a link), propagation models (loss of different frequency band space propagation), building penetration loss and other data. According to the building test traversal method, manual CQT test is carried out through a 5G test terminal and software, and the current 5G coverage condition can be evaluated most accurately. And the 5G MR positioning mode (such as MDT, a fingerprint database and the like) refers to the 4G MR positioning mode, acquires 5G MR positioning data, and counts sampling points and levels positioned in the building to represent the building coverage condition.
The existing building coverage construction scheme determination methods have the problems of high measurement cost and insufficient measurement precision. The coverage condition of the 5G signals in the building is evaluated through 5G simulation software, and due to the fact that needed work parameters are many and the work parameters cannot be completely and accurately consistent with the actual condition of the existing network, for example, longitude and latitude, height, link budget and penetration loss are set through human estimation and have great difference with the actual condition; the propagation model correction is generally a general model for each scene, and the propagation losses of all actual places are different, so the simulation is generally more suitable for the whole network macroscopic statistical analysis, and the accurate fixed-point evaluation is often different from the actual test. According to the building test traversal method, 5G outdoor stations around a lot of buildings are planned and constructed, the built effect is difficult to confirm, in addition, the manual test cost is high, and large-scale coverage analysis and evaluation cannot be carried out except individual scenes actually. Due to the fact that the number of 5G MRs is too small at present through a 5G MR positioning mode (such as MDT, a fingerprint database and the like), samples are not enough to support coverage statistics, and meanwhile, 5G base stations in many places are not planned or built. In addition, the 5GMR positioning mode is not as mature as that of 4G, and 4G MR positioning is not very accurate due to the problems of working parameter accuracy, reported data precision error and the like.

and 200, determining that the target building has indoor coverage of a 4G indoor sub-coverage system.
The floor 1-3 area in the building coverage area related to the design scheme is taken as an example for explanation, the floor 1-3 area is covered by two cells, the first cell is provided with a sampling points, the second cell is provided with b sampling points, and each sampling point is provided with a plurality of 4G outdoor receiving coverage levels corresponding to the measured outdoor neighboring cells and frequency bands corresponding to the frequency points of the neighboring cells. And counting the received coverage levels of the 4G outdoor adjacent cells reported by the measurement of the a sampling points of the first cell and the b sampling points of the second cell to obtain the first 4G coverage condition of the floor 1-3 area.
And 202, calculating the level of the target building after upgrading the 5G base station according to the first 4G coverage conditions of different areas.
Specifically, the level after the 5G base station is upgraded in the same address of the relevant cell can be calculated according to the 4G outdoor neighboring cell reception coverage levels measured and reported by the sampling points in different areas in step 201, and by combining the propagation model, the positions of the neighboring cells, the building loss, and the difference between the 4G link and the 5G link, each sampling point has a plurality of measured 4G outdoor reception coverage levels of the outdoor neighboring cells, and a plurality of 5G converted reception levels corresponding to each sampling point can be calculated correspondingly, so that the level after the target building is upgraded to the 5G base station is obtained.
And 203, determining the current 5G coverage rate and the predicted 5G coverage rate corresponding to the target building based on the level of the target building after upgrading the 5G base station.
Specifically, according to the multiple 5G converted receiving levels corresponding to each sampling point calculated in step 202, sampling points meeting preset conditions are selected, and according to the number of the sampling points meeting the preset conditions, the current 5G coverage rate and the predicted 5G coverage rate corresponding to the target building are determined. When the current 5G coverage rate is calculated, the sampling points meeting the preset conditions comprise the measured sampling points of the outdoor 4G station upgraded to the 5G station, and do not comprise the 5G subsequent construction station. And when the predicted 5G coverage rate is calculated, the sampling points meeting the preset conditions comprise the measured sampling points of the upgraded outdoor 4G station and the sampling points of the non-upgraded outdoor 4G station as the 5G stations.
And 204, determining a 5G coverage construction scheme corresponding to the target building according to the current 5G coverage and the predicted 5G coverage.

For example, if the current 5G coverage rate is greater than a preset 5G indoor coverage rate, it is determined that the target area does not need to be built for 5G indoor coverage; if the current 5G coverage rate is smaller than a preset 5G indoor coverage rate and the predicted 5G coverage rate is larger than the preset 5G indoor coverage rate, determining to upgrade an outdoor station which is not upgraded to a 5G station and corresponds to the target area; and if the predicted 5G coverage rate is smaller than the preset 5G indoor coverage rate, determining that the target area needs to be built for 5G indoor coverage. And determining a 5G coverage construction scheme corresponding to the target building based on the 5G coverage construction schemes corresponding to different areas.
According to the embodiment of the invention, the level of the 5G base station upgraded at the same site is estimated by combining the outdoor sampling statistics of the MR adjacent region of the existing 4G room with the difference of the 4G link and the 5G link, so that the coverage condition in a real building can be accurately positioned. Because the measured level actually occurs indoors, the geographic position is the most accurate, and in addition, because the 4G outdoor acquisition of the adjacent region is adopted, the coverage effect estimation after the co-site construction can be carried out on the points which are not constructed by 5G. The coverage conditions of different floors of the building are positioned by floor areas, so that the areas where the 5G rooms need to be planned and constructed actually are positioned more accurately, and the building 5G coverage construction scheme is determined.
Fig. 3 is a third flowchart of a method for determining a building 5G coverage construction plan according to an embodiment of the present invention, as shown in fig. 3, in an embodiment, the method includes the following steps:
and step 300, determining that the target building does not have indoor coverage of the 4G indoor sub-coverage system.
The MDT (Minimization of Drive-tests) is an automatic Drive test technology introduced by 3GPP in the LTE system for acquiring and reporting measurement data of a general user/commercial terminal through network configuration, and as long as the user terminal turns on the GPS and supports the MDT function, the terminal can automatically report MDT data including user location information to the base station. MDT and MR are similar, comprise RSRP, RSRQ and other fields, contain GPS longitude and latitude information and can be used for big data analysis.
Specifically, the second 4G coverage condition of the target building boundary can be obtained by MR grid positioning or MDT data calculation, the MDT data has sampling point longitude and latitude, sampling points and levels in the building are counted in combination with the building boundary, and the obtained second 4G coverage condition includes a plurality of outdoor level 4G outdoor macro-station MR sampling points and a plurality of levels corresponding to each sampling point.
And 302, calculating the level of the target building after upgrading the 5G base station according to the second 4G coverage condition.
Specifically, according to the 4G outdoor macro-station MR sampling points and levels of the outdoor levels in step 301, the levels of the sampling points after the 5G base station is upgraded at the same site can be calculated by combining the propagation model, the peripheral cell positions, the building loss and the 4G and 5G link differences, each 4G outdoor macro-station MR sampling point corresponds to a plurality of levels, a plurality of 5G reduced receiving levels of each sampling point can be correspondingly calculated, and the levels of the target building after the 5G base station is upgraded are obtained.
And step 303, determining the current 5G coverage rate and the predicted 5G coverage rate corresponding to the target building based on the level of the target building after upgrading the 5G base station.
Specifically, according to the multiple 5G converted receiving levels corresponding to each sampling point calculated in step 302, sampling points meeting preset conditions are selected, and according to the number of the sampling points meeting the preset conditions, the current 5G coverage rate and the predicted 5G coverage rate corresponding to the target building are determined. When the current 5G coverage rate is calculated, the sampling points meeting the preset conditions comprise the measured sampling points of the outdoor 4G station upgraded to the 5G station, and do not comprise the 5G subsequent construction station. And when the predicted 5G coverage rate is calculated, the sampling points meeting the preset conditions comprise the measured sampling points of the upgraded outdoor 4G station and the sampling points of the non-upgraded outdoor 4G station as the 5G stations.
And step 304, determining a 5G coverage construction scheme corresponding to the target building according to the current 5G coverage and the predicted 5G coverage.
Specifically, a preset 5G indoor coverage rate can be determined according to a 5G indoor coverage rate obtained by an operator based on user perception requirements, namely the proportion of sampling points in the building, which are larger than a certain minimum level threshold, and a 5G coverage construction scheme corresponding to the target building is determined according to the relation between the preset 5G indoor coverage rate and the current 5G coverage rate and the predicted 5G coverage rate. For example, if the current 5G coverage rate is greater than a preset 5G indoor coverage rate, it is determined that the target area does not need to be built for 5G indoor coverage; if the current 5G coverage rate is smaller than a preset 5G indoor coverage rate and the predicted 5G coverage rate is larger than the preset 5G indoor coverage rate, determining to upgrade an outdoor station which is not upgraded to a 5G station and corresponds to the target area; and if the predicted 5G coverage rate is smaller than the preset 5G indoor coverage rate, determining that the target area needs to be built for 5G indoor coverage. And determining a 5G coverage construction scheme corresponding to the target building based on the 5G coverage construction schemes corresponding to different areas.
According to the embodiment of the invention, the sampling points falling on the inner side of the building are counted by adopting a relatively mature 4GMR positioning mode for the building without 4G rooms, and then the coverage condition of the site opened or planned by 5G at the same address is calculated by link conversion. For some buildings with large building areas, the outdoor level of the building can be counted, and the coverage interval of the coverage level is roughly calculated by combining the wall partition condition of the design drawing. Compared with 5G MR positioning, the method has the advantages that on one hand, the MR data volume is larger and more objective, on the other hand, the positioning method is more mature at present, and the precision is higher relative to 5G.
In one embodiment, the level after the target building is upgraded to the 5G base station is calculated in step 202 or step 302 by the following method:
and calculating the level of the target building after upgrading the 5G base station by adopting a preset 4G and 5G coverage conversion relation, wherein the preset 4G and 5G coverage conversion relation is expressed by adopting the following formula:
the 5G converted receiving level =4G receiving level +4/5G site transmitting power difference +4/5G antenna gain difference +4/5G terminal receiving capacity difference +4/5G frequency coverage difference delta;
wherein the 4/5G frequency coverage difference Δ =20 × log (bin 1/bin 2).
The 4/5G frequency coverage difference Δ may be converted according to a free space propagation model L =32.5+20 log (frequency band) +20 log (distance), and when the distances are consistent, different frequency band values are substituted, so that the path loss difference between different frequency bands is Δ =20 log (frequency band 1/frequency band 2), and when 4G and 5G co-stations in the scheme, the distances are consistent, so that the 4/5G frequency coverage difference Δ =20 log (frequency band 1/frequency band 2).
According to the embodiment of the invention, the preset 4G and 5G coverage conversion relation is combined with the 4/5G site transmitting power difference, the 4/5G antenna gain difference, the 4/5G terminal receiving capacity difference and the 4/5G frequency coverage difference delta, so that the accuracy of the calculated level of the target building after upgrading the 5G base station is improved, and the accuracy of scheme determination is improved.
In one embodiment, the determining the current 5G coverage rate and the predicted 5G coverage rate corresponding to the target building based on the level of the target building after upgrading the 5G base station in step 202 or step 302 specifically includes the following steps:
step 400, if the number of the target area sampling points is the first number, determining the first sampling point of each sampling point, wherein the maximum value of the 5G converted receiving level is greater than the 5G access coverage level threshold.
Specifically, a plurality of sampling points exist in the target area, each sampling point corresponds to a plurality of 5G converted receiving levels, and if the maximum value of the plurality of 5G converted receiving levels corresponding to a single sampling point is greater than the 5G access coverage level threshold, the sampling point is a first sampling point, otherwise, if the maximum value of the plurality of 5G converted receiving levels corresponding to a single sampling point is less than or equal to the 5G access coverage level threshold, the sampling point is not a first sampling point, and thus, the first sampling point of the sampling points in the target area is determined.
And 401, counting the number of the second sampling points of the outdoor 4G station upgraded to the 5G station in the first sampling points.
Specifically, the outdoor 4G station measured by the first sampling point may have been upgraded to a 5G station or not upgraded to the 5G station, the sampling point of the outdoor 4G station measured by the first sampling point that has been upgraded to the 5G station is determined to be a second sampling point, and the number of the second sampling points is counted.
And 402, counting the number of the third sampling points of the outdoor 4G sites which are measured in the first sampling points and are not upgraded to the 5G sites.
Specifically, the outdoor 4G station measured by the first sampling point may have been upgraded to a 5G station or not upgraded to a 5G station, the sampling point of the first sampling point, where the outdoor 4G station measured by the first sampling point has not been upgraded to a 5G station, is determined to be a third sampling point, and the number of the third sampling points is counted.
And step 403, determining the current 5G coverage rate corresponding to the target area according to the second number of sampling points and the first number.
Specifically, the current 5G coverage rate corresponding to the target area can be determined according to the proportion of the second sampling point number in the first number.
For example, cell 1 has a sampling points, the number of sampling points in each sampling point, whose maximum value after the 4G reception level is converted into the 5G level is greater than the 5G access coverage level threshold after measurement, is Na, na1 is the number of sampling points measured that the outdoor 4G station has been upgraded to the cell of the 5G station, na2 is the number of sampling points measured that the outdoor 4G station has not been upgraded to the cell of the 5G station, and Na = Na1+ Na2.
The cell 2 has b sampling points, the number of the sampling points in each sampling point, which is measured that the maximum value after the 4G receiving level is converted into the 5G level is greater than the threshold of the 5G access coverage level, is Nb, nb1 is the number of the measured sampling points of the cell in which the outdoor 4G station has been upgraded to the 5G station, nb2 is the number of the measured sampling points of the cell in which the outdoor 4G station has not been upgraded to the 5G station, and Nb = Nb1+ Nb2.
In addition, for Na2 and Nb2, the stations can be split according to the number of outdoor stations, for example, two stations can be split into Na2 and Na3, so that the effect of outdoor construction 2 or 3 or both 2 and 3 can be judged respectively, and outdoor macro-station coverage can be selectively constructed.
Floor 1-3 zone currently 5G coverage = (Na 1+ Nb 1)/(a + b).
And 404, determining the predicted 5G coverage rate corresponding to the target area according to the number of the second sampling points, the number of the third sampling points and the first number.
Specifically, the predicted 5G coverage corresponding to the target area can be determined according to the proportion of the sum of the second number of sample points and the third number of sample points in the first number.
For example, cell 1 has a sampling points, the number of sampling points in each sampling point, whose maximum value after the 4G reception level is converted into the 5G level is greater than the 5G access coverage level threshold after measurement, is Na, na1 is the number of sampling points measured that the outdoor 4G station has been upgraded to the cell of the 5G station, na2 is the number of sampling points measured that the outdoor 4G station has not been upgraded to the cell of the 5G station, and Na = Na1+ Na2.
The cell 2 has b sampling points, the number of the sampling points in each sampling point, which is greater than the threshold of 5G access coverage level after the 4G receiving level is converted into 5G level, is measured, nb1 is the number of the sampling points of the cell where the outdoor 4G station has been upgraded to the 5G station, nb2 is the number of the sampling points of the cell where the outdoor 4G station has not been upgraded to the 5G station, and Nb = Nb1+ Nb2.
Floor 1-3 zone prediction 5G coverage = (Na 1+ Na2+ Nb1+ Nb 2)/(a + b).
According to the embodiment of the invention, the current 5G coverage rate and the predicted 5G coverage rate are calculated according to the number of the second sampling points, the number of the third sampling points and the first number, so that the accuracy of the determined current 5G coverage rate and the predicted 5G coverage rate corresponding to the target building is improved, and then the 5G coverage construction scheme corresponding to the target building is determined according to the current 5G coverage rate and the predicted 5G coverage rate, so that the scheme determination cost is reduced, and the accuracy of scheme determination is improved.
In one embodiment, the step 202 or the step 302 of determining the 5G coverage construction scheme corresponding to the target building according to the current 5G coverage and the predicted 5G coverage specifically includes the following steps:
step 500, if the current 5G coverage rate is greater than a first preset threshold, determining that the target area does not need to be covered by a 5G indoor area.
Specifically, the current 5G coverage is greater than the first preset threshold, which indicates that the current 5G coverage in the target area meets the requirement, and therefore, the target area does not need to be covered by 5G indoor.
Step 501, if the current 5G coverage is smaller than a first preset threshold and the predicted 5G coverage is larger than the first preset threshold, determining to upgrade the outdoor station which is not upgraded to the 5G station and corresponds to the target area.
Specifically, the current 5G coverage is smaller than a first preset threshold, which indicates that the current 5G coverage in the target area cannot meet the requirement, and the 5G site needs to be upgraded or 5G indoor coverage needs to be built, and because the predicted 5G coverage is larger than the first preset threshold, and when the predicted 5G coverage is calculated, the sampling points meeting the preset condition include the measured sampling points of the outdoor 4G site that is upgraded and the sampling points of the outdoor 4G site that is not upgraded, it is determined that the outdoor site corresponding to the target area that is not upgraded to the 5G site is upgraded.
Step 502, if the predicted 5G coverage rate is smaller than a first preset threshold, determining that a target area needs to be covered by 5G indoor coverage.
Specifically, because the current 5G coverage is equal to or less than the predicted 5G coverage, if the predicted 5G coverage is less than the first preset threshold, the current 5G coverage is less than the first preset threshold, which indicates that the current 5G coverage in the target area cannot meet the requirement, the 5G site needs to be upgraded or the 5G indoor coverage needs to be built, and because the predicted 5G coverage is less than the first preset threshold, that is, the upgraded 5G coverage still cannot meet the requirement, the target area needs to be built with the 5G indoor coverage.
Step 503, determining a 5G coverage construction scheme corresponding to the target building based on the 5G coverage construction schemes corresponding to different areas.
Specifically, the 5G coverage construction scheme corresponding to the target building is finally determined according to outdoor opening requirements and indoor construction requirements corresponding to each region of the whole building, combined investment, construction progress and the like. The 5G coverage construction scheme corresponding to the target building comprises coverage by indoor partition construction, coverage by outdoor current 5G macro-station or subsequent coverage by constructed 5G macro-station.
According to the embodiment of the invention, the 5G construction scheme of each area is determined based on the current 5G coverage rate and the size relation between the predicted 5G coverage rate and the first preset threshold value, and the 5G coverage construction scheme corresponding to the target building is determined based on the 5G coverage construction schemes corresponding to different areas, so that the scheme determination cost is reduced, and the scheme determination accuracy is improved.
In one embodiment, if the sample of the sampling point of the 4G outdoor macro station MR located at the target building is not enough to judge the 5G coverage condition of the target building, the following steps are executed:
step 600, calculating a third 4G coverage condition of the adjacent area outside the boundary of the target building according to the MR grid positioning or MDT data, wherein the third 4G coverage condition comprises 4G MR sampling points and levels of outdoor levels of the adjacent area outside the boundary of the target building.
Specifically, for some large buildings, when samples of sampling points of 4G outdoor macro-station MR positioning falling in the buildings are found to be too few to judge the building coverage condition after positioning, the 4G MR sampling points and the level condition of outdoor levels of adjacent areas outside the building boundary are calculated according to MR grid positioning or MDT data. And counting the sampling points and levels of the first-layer grids outside the building by combining the longitude and the latitude of the MDT data with the sampling points and the building boundary.
Step 601, according to the third 4G coverage condition, calculating the level of the target building after upgrading the 5G base station.
Specifically, the level of the relevant cell after the 5G base station is upgraded at the same address is calculated through the coverage conversion relation between the 5G base station and the 4G base station. The 5G and 4G coverage conversion relationship has been described in the above embodiments, and is not described herein again to avoid repetition.
And step 602, determining the predicted indoor minimum 5G receiving level of the building corresponding to the target building based on the level of the target building after upgrading the 5G base station.
Specifically, a 5G reception level in a first wall of the building is calculated according to an electronic map, wherein the 5G reception level = an outdoor reception level-a penetration loss level. Indoor maximum 5G receiving levels obtained after different outdoor grid cells are converted are arranged in different regions of the large building in the south, the west and the north, and meanwhile if a building internal structure drawing exists, the 5G levels in a building depth region are further converted according to space propagation loss corresponding to space distance and penetrating loss corresponding to a wall body, so that the indoor minimum 5G receiving levels predicted by the building are obtained. The method is similar to the current indoor building simulation, and finally the buildings with too few positioning sampling points can be obtained.
And 603, determining a 5G coverage construction scheme corresponding to the target building according to the predicted indoor minimum 5G receiving level of the building.
Specifically, the 5G level of the building depth area is further converted according to the space propagation loss corresponding to the space distance and the penetration loss corresponding to the wall body, so that the indoor minimum 5G receiving level predicted by the building is obtained, and the 5G coverage construction scheme corresponding to the target building is determined according to the indoor minimum 5G receiving level predicted by the building.
According to the embodiment of the invention, when the sampling point samples of the target building are not enough to judge the 5G coverage condition of the target building, the 5G coverage construction scheme corresponding to the target building is determined according to the indoor minimum 5G receiving level predicted by the building corresponding to the target building, so that the deviation of scheme determination caused by insufficient sampling points is avoided, and the accuracy of scheme determination is improved.

According to the building 5G coverage construction scheme determining device provided by the embodiment of the invention, the level of the 5G base station upgraded at the same address is estimated by combining the outdoor sampling statistics of the MR adjacent region of the existing 4G indoor division with the difference of the 4G link and the 5G link, so that the coverage condition in a real building can be accurately positioned. Because the measured level actually occurs indoors, the geographic position is the most accurate, and in addition, because the 4G outdoor acquisition of the adjacent region is adopted, the coverage effect estimation after the co-site construction can be carried out on the points which are not constructed by 5G.

For some buildings with large building areas, the outdoor level of the building can be counted, and the coverage interval of the coverage level is roughly calculated by combining the wall partition condition of the design drawing.
