Description

Building 5G coverage construction scheme determining method, device, equipment and storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for determining a building 5G coverage construction scheme.

Background

In the 5G revolution, 5G network development has enabled the internet of things industry to emerge more innovative solutions. More services are made possible. The intelligent building market presents a blowout situation, and the intelligent building becomes more efficient in management, accurate in service, low in consumption and environment-friendly due to the addition of 5G, and presents great interactivity.

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 traversing method or a 5G MR positioning mode. The 5G simulation software evaluates the coverage condition of 5G signals in the building, and mainly combines the data of base station parameters (including information such as base station position, height, power parameters and the like), link budget (signal loss and gain on a link), propagation model (loss propagated in different frequency band spaces), building penetration loss and the like to finally calculate the coverage condition in the building. According to the building test traversing method, the manual CQT test is carried out through the 5G test terminal and software, and the coverage condition of the current 5G can be estimated most accurately. And 5G MR positioning modes (such as MDT, fingerprint library and the like) refer to a 4G MR positioning mode, 5G MR positioning data are collected, and sampling points and levels positioned in a building are counted to represent the building coverage condition.

In the existing building coverage construction scheme determining method, the problems of high measurement cost and insufficient measurement precision exist. The 5G simulation software is used for evaluating the coverage condition of 5G signals in a building, and as the required working parameters are quite large, the coverage condition of the 5G signals can not be completely and accurately consistent with the actual condition of the existing network, for example, the longitude and latitude, the altitude, the link budget and the penetration loss are artificially estimated and set, and the coverage condition is quite different from the actual condition; the propagation model correction is generally a scene-based universal model, and the propagation loss of each actual place is different, so that the simulation is generally more suitable for whole-network macroscopic statistical analysis, and the difference between accurate fixed-point evaluation and actual test is larger. The building test traversing method is used for planning and constructing a plurality of building peripheral 5G outdoor sites, the built effect is difficult to confirm, in addition, the manual test cost is high, and large-scale coverage analysis and evaluation can not be carried out except for individual scenes. With 5G MR positioning (e.g., MDT, fingerprint library, etc.), the current 5G MR is too few, the samples are insufficient to support coverage statistics, and many local 5G base stations have not yet been planned or built. In addition, the 5GMR positioning mode is not as mature as that of 4G, and the 4G MR positioning is not very accurate because of the problems of industrial parameter accuracy, reported data accuracy error and the like.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The building 5G coverage construction scheme determination method of the present invention is described below with reference to fig. 1 to 3.

Fig. 1 is one of flowcharts of a building 5G coverage construction scheme determining method according to an embodiment of the present invention, and in one embodiment, as shown in fig. 1, includes the following steps:

step 100, determining whether the target building has a 4G indoor coverage system indoor coverage.

Specifically, whether the target building has the 4G coverage scheme can be determined by the operator's building division industry to determine whether the building has the 4G coverage system, or whether the target building has the 4G coverage system by the design drawing of the target building, which is not limited herein.

Step 101, under the condition that a target building has indoor coverage of a 4G indoor coverage system, building coverage related to a design scheme is obtained, first 4G coverage conditions of different areas are counted based on the building coverage, and a 5G coverage construction scheme corresponding to the target building is determined according to the first 4G coverage conditions of the different areas.

Specifically, in step 100, when it is determined that the target building has indoor coverage of the 4G indoor coverage system, building coverage related to the design scheme of the target building is obtained, and based on the first 4G coverage condition of different areas of the building coverage statistics, the building coverage is generally different floors corresponding to different cells, and the building coverage can be divided into different areas, for example, floor 1-3 areas and floor 4-6 areas. And determining a 5G coverage construction scheme corresponding to the target building according to the first 4G coverage conditions of the different areas.

Optionally, according to the first 4G coverage conditions of different areas, a 5G coverage construction scheme corresponding to the different areas may be determined, and finally the 5G coverage construction scheme corresponding to the target building is formed. And whether the building is covered by indoor construction or outdoor current 5G macro stations or 5G macro stations of subsequent construction can be determined according to outdoor opening requirements and indoor construction requirements corresponding to all areas of the whole building, combined investment, construction progress and the like.

Step 102, under the condition that a target building does not have indoor coverage of a 4G indoor coverage system, acquiring a second 4G coverage condition of the boundary of the target building, and determining a 5G coverage construction scheme corresponding to the target building according to the second 4G coverage condition.

Specifically, in step 100, under the condition that it is determined that the target building does not have indoor coverage of the 4G indoor coverage system, a second 4G coverage condition of the boundary of the target building is obtained, and according to the second 4G coverage condition, a 5G coverage construction scheme corresponding to the target building is determined.

The building 5G coverage construction scheme determining method provided by the embodiment of the invention can accurately position the real building coverage situation, and determine the 5G coverage construction scheme of the target building according to the 4G coverage situation, thereby reducing the scheme determining cost and improving the scheme determining accuracy.

Fig. 2 is a second flowchart of a building 5G coverage construction scheme determining method according to an embodiment of the present invention, as shown in fig. 2, in one embodiment, the method includes the following steps:

step 200, determining that the target building has indoor coverage of the 4G indoor coverage system.

Step 201, acquiring building coverage related to a design scheme, and counting first 4G coverage conditions of different areas according to MR data of 4G indoor sub-areas of different areas, wherein the first 4G coverage conditions comprise: and measuring the reported 4G outdoor neighbor cell receiving coverage level by a plurality of sampling points in different areas and each sampling point.

Taking a floor 1-3 area in a building coverage area related by a design scheme as an example for explanation, the floor 1-3 area is covered by two cells, a first cell is provided with a sampling point, a second cell is provided with b sampling points, and each sampling point is provided with a plurality of corresponding measured 4G outdoor receiving coverage levels of an outdoor neighboring cell and a frequency band of the neighboring cell. And counting a sampling point a of the first cell and a sampling point b of the second cell, measuring the reported 4G outdoor neighbor cell receiving coverage level, and obtaining a first 4G coverage condition of the floor 1-3 area.

Step 202, calculating the level of the target building after upgrading the 5G base station according to the first 4G coverage conditions of the different areas.

Specifically, according to the reported 4G outdoor neighboring cell receiving coverage levels measured by the sampling points in the different areas in step 201, the levels after the related cell is co-located and upgraded with the 5G base station can be calculated by combining the propagation model, the surrounding cell position, the building loss and the 4G and 5G link difference, each sampling point has a plurality of corresponding measured 4G outdoor receiving coverage levels of the outdoor neighboring cell, and a plurality of corresponding 5G converted receiving levels of each sampling point can be calculated, so as to obtain the levels after the target building is upgraded with the 5G base station.

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 the 5G base station is upgraded.

Specifically, according to the plurality of 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 sampling points meeting 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 which is updated to the 5G station, and the sampling points do not comprise the 5G subsequent station. When calculating the predicted 5G coverage rate, the sampling points meeting the preset condition comprise the measured sampling points of the outdoor 4G station which are upgraded and not upgraded to the 5G station.

And 204, determining a 5G coverage construction scheme corresponding to the target building according to the current 5G coverage and the predicted 5G coverage.

Specifically, according to the 5G indoor coverage rate obtained by an operator based on user perception requirements, namely the proportion of sampling points in the building which is larger than a certain minimum level threshold, a preset 5G indoor coverage rate can be determined, and according to the relation between the preset 5G indoor coverage rate and the current 5G coverage rate and the predicted 5G coverage rate, a 5G coverage construction scheme corresponding to the target building is determined. For example, if the current 5G coverage rate is greater than a preset 5G indoor coverage rate, determining that the target area does not need to be covered in a 5G indoor mode; 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 site which is not upgraded to a 5G site 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 constructed with the 5G indoor coverage rate. And determining the 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 coverage condition in a real building can be accurately positioned by combining the outdoor sampling statistics of the MR adjacent cells of the existing 4G room division with the level after the 5G base station is upgraded by the same address through the 4G and 5G link difference estimation. The method is characterized in that the level actually generated indoors is measured, the geographic position is the most accurate, and in addition, 4G outdoor collection of the neighboring cells is adopted, so that coverage effect estimation after co-location construction can be performed on points where 5G is not yet constructed. The coverage conditions of different layers of the building are positioned according to the floor areas, so that the areas of the 5G room which are actually required to be planned and constructed are positioned more accurately, and the coverage construction scheme of the building 5G is determined.

Fig. 3 is a third flowchart of a building 5G coverage construction scheme determining method according to an embodiment of the present invention, as shown in fig. 3, in one embodiment, the method includes the following steps:

step 300, determining that the target building has no indoor coverage of the 4G indoor coverage system.

Step 301, calculating a second 4G coverage condition of the boundary of the target building according to the MR grid positioning or the MDT data, wherein the second 4G coverage condition includes an MR sampling point and an MR level of a 4G outdoor macro station of an outdoor level.

The MDT (Minimization of Drive-tests, minimization of drive tests) is an automatic drive test technology introduced by 3GPP in the LTE system, wherein the automatic drive test technology performs measurement data acquisition and reporting on a common user/commercial terminal through network configuration, and the terminal can automatically report MDT data containing user position information to a base station as long as the user terminal starts the GPS and supports the MDT function. MDT is similar to MR, contains fields such as RSRP, RSRQ and the like, contains GPS longitude and latitude information, and can be used for big data analysis.

Specifically, the second 4G coverage condition of the target building boundary may be obtained by MR grid positioning or MDT data calculation, where the MDT data includes longitude and latitude of sampling points, and by combining with the building boundary, statistics is performed on sampling points and levels in the building, where the obtained second 4G coverage condition includes multiple outdoor level 4G outdoor macro station MR sampling points and multiple 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 MR sampling points and the levels of the outdoor level in step 301, the levels of the 5G base station after the 5G base station is upgraded in the same address of each sampling point can be calculated by combining the propagation model, the surrounding cell positions, the building loss and the 4G and 5G link differences, each 4G outdoor macro MR sampling point corresponds to a plurality of levels, and a plurality of 5G converted receiving levels of each sampling point can be calculated correspondingly, so as to obtain the levels of the 5G base station after the target building is upgraded.

And 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 the 5G base station is upgraded.

Specifically, according to the plurality of 5G converted receiving levels corresponding to each sampling point calculated in step 302, sampling points meeting a preset condition are selected, and according to the number of sampling points meeting the preset condition, 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 which is updated to the 5G station, and the sampling points do not comprise the 5G subsequent station. When calculating the predicted 5G coverage rate, the sampling points meeting the preset condition comprise the measured sampling points of the outdoor 4G station which are upgraded and not upgraded to the 5G station.

And 304, determining a 5G coverage construction scheme corresponding to the target building according to the current 5G coverage and the predicted 5G coverage.

According to the embodiment of the invention, the coverage condition of the site with the same site 5G opened or planned is calculated through link conversion by adopting a relatively mature 4GMR positioning mode for the building without the 4G room division to count the sampling points at the inner side of the building. For some buildings with larger building areas, the outdoor level of the building can be counted, and the coverage area of the coverage level is calculated approximately by combining the partition condition of the wall body 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 mature, and the accuracy is higher than that of 5G.

In one embodiment, the level of the target building after upgrading the 5G base station is calculated in step 202 or step 302, specifically 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:

wherein the 4/5G frequency coverage difference Δ=20×log (band 1/band 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), where under the condition of consistent distance, different frequency band values are substituted, so that the path loss difference value of different frequency bands is Δ=20×log (frequency band 1/frequency band 2), and under the condition of 4G and 5G co-station in the present embodiment, the distances are considered 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 capability difference and the 4/5G frequency coverage difference delta, so that the accuracy of the calculated level of the target building after the 5G base station is upgraded is improved, and the accuracy of scheme determination is improved.

In one embodiment, the determining, in step 202 or step 302, 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 includes the following steps:

step 400, if the number of sampling points in the target area is the first number, determining a first sampling point in each sampling point, where 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, if the maximum value of the plurality of 5G converted receiving levels corresponding to a single sampling point is greater than a 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 the single sampling point is less than or equal to the 5G access coverage level threshold, the sampling point is not the first sampling point, and therefore the first sampling point in the sampling points of the target area is determined.

Step 401, counting the number of second sampling points of the outdoor 4G station which is measured in the first sampling points and is updated to the 5G station.

Specifically, the outdoor 4G station measured at the first sampling point may have been upgraded to a 5G station or not to a 5G station, the sampling points measured at the first sampling point at which the outdoor 4G station has been upgraded to a 5G station are determined to be second sampling points, and the number of second sampling points is counted.

And step 402, counting the number of third sampling points, which are measured in the first sampling points and are not updated to 5G sites, of the outdoor 4G sites.

Specifically, the outdoor 4G station measured at the first sampling point may have been upgraded to the 5G station or not, the sampling point measured at the first sampling point at which the outdoor 4G station has not been upgraded to the 5G station is determined to be the third sampling point, and the number of the third sampling points is counted.

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, according to the proportion of the second sampling point number in the first number, the current 5G coverage rate corresponding to the target area can be determined.

For example, cell 1 has a number of sampling points, where the number of sampling points in each sampling point, where the maximum value of the measured 4G reception level after being converted into the 5G level is greater than the 5G access coverage level threshold is Na, na1 is the number of sampling points where the measured outdoor 4G station has been upgraded to the 5G site cell, na2 is the number of sampling points where the measured outdoor 4G station has not been upgraded to the 5G site cell, and na=na1+na2.

The cell 2 has b sampling points, the number of sampling points in each sampling point, where the maximum value of the measured 4G receiving level after being converted into the 5G level is greater than the 5G access coverage level threshold is Nb, nb1 is the number of sampling points of the measured cell in which the outdoor 4G station has been upgraded to the 5G station, nb2 is the number of sampling points of the measured 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 outdoor macro station coverage can be selectively constructed by splitting the outdoor macro station coverage according to the number of outdoor stations, for example, two stations can be split into Na2 and Na3, and thus the construction effect of outdoor construction 2 or 3 or both 2 and 3 can be respectively judged.

Floor 1-3 area current 5G coverage= (Na 1+ Nb 1)/(a + b).

And step 404, determining the predicted 5G coverage rate corresponding to the target area according to the second sampling point number, the third sampling point number and the first number.

Specifically, according to the proportion of the sum of the second sampling point number and the third sampling point number in the first number, the predicted 5G coverage rate corresponding to the target area can be determined.

Floor 1-3 area 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 second sampling point number, the third sampling point number and the first sampling point number, so that the accuracy of the current 5G coverage rate and the predicted 5G coverage rate corresponding to the determined target building is improved, the 5G coverage construction scheme corresponding to the target building is further determined according to the current 5G coverage rate and the predicted 5G coverage rate, the scheme determination cost is reduced, and the scheme determination accuracy is improved.

In one embodiment, in step 202 or step 302, according to the current 5G coverage rate and the predicted 5G coverage rate, a 5G coverage construction scheme corresponding to the target building is determined, which specifically includes the following steps:

and 500, if the current 5G coverage rate is greater than a first preset threshold value, determining that the target area does not need to be covered in a 5G room.

Specifically, the current 5G coverage rate is greater than a first preset threshold, which indicates that the current 5G coverage rate in the target area has satisfied the requirement, so that the target area does not need to construct 5G indoor coverage.

Step 501, if the current 5G coverage rate is smaller than a first preset threshold, and the predicted 5G coverage rate is greater 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 rate is smaller than a first preset threshold, which indicates that the current 5G coverage rate in the target area cannot meet the requirement, and 5G station upgrading or 5G indoor coverage construction is required, and because the predicted 5G coverage rate is larger than the first preset threshold and the calculated predicted 5G coverage rate, sampling points meeting the preset conditions include the measured sampling points of the outdoor 4G station which is upgraded and not upgraded to the 5G station, the outdoor station which is not upgraded to the 5G station and corresponds to the target area is determined to be upgraded.

Step 502, if the predicted 5G coverage rate is smaller than a first preset threshold, determining that the target area needs to be covered in a 5G room.

Specifically, because the current 5G coverage rate is less than or equal to the predicted 5G coverage rate, if the predicted 5G coverage rate is less than the first preset threshold value, the current 5G coverage rate is less than the first preset threshold value, which indicates that the current 5G coverage rate in the target area cannot meet the requirement, and the 5G station is required to be upgraded or the 5G indoor coverage is required to be constructed, and because the predicted 5G coverage rate is less than the first preset threshold value, that is, the upgraded 5G coverage rate still cannot meet the requirement, the target area is determined to be required to be constructed.

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, finally, determining a 5G coverage construction scheme corresponding to the target building according to outdoor opening requirements and indoor construction requirements corresponding to each region of the whole building, investment, construction progress and the like. The 5G coverage construction scheme corresponding to the target building comprises coverage through indoor division construction, coverage through an outdoor current 5G macro station or subsequent coverage through a 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 insufficient to determine the 5G coverage condition of the target building, the following steps are performed:

and 600, calculating a third 4G coverage condition of the adjacent area outside the boundary of the target building according to 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 the sampling point samples of the 4G outdoor macro station MR positioned in the building are found to be too small enough to judge the coverage condition of the building after positioning, the 4G MR sampling point and the level condition of the outdoor level of the adjacent area outside the boundary of the building are calculated according to MR grid positioning or MDT data. MDT data is provided with sampling points and longitudes, and the sampling points and the levels of a first layer grid outside a building are counted by combining building boundaries.

And 601, calculating the level of the target building after upgrading the 5G base station according to the third 4G coverage condition.

Specifically, the level after the 5G base station is upgraded in the same address of the relevant cell is calculated through the 5G and 4G coverage conversion relation. The 5G and 4G coverage conversion relationships have been described in the above embodiments, and are not repeated here.

Step 602, determining the indoor minimum 5G receiving level of the building prediction 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 the first wall of the building, 5G reception level=outdoor reception level-penetration loss level, is calculated from the electronic map. And meanwhile, if a building internal structure drawing is provided, the 5G level of the building depth area is further converted according to the space propagation loss corresponding to the space distance and the wall body corresponding penetration loss, so that the indoor minimum 5G receiving level predicted by the building is obtained. The method is similar to the current indoor building simulation, and finally the building 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 wall penetration loss corresponding to the wall, so that the 5G receiving level with the smallest indoor space predicted by the building is obtained, and the 5G coverage construction scheme corresponding to the target building is determined according to the 5G receiving level with the smallest indoor space predicted by the building.

According to the embodiment of the invention, when the sampling point sample of the target building is insufficient to judge the 5G coverage condition of the target building, the 5G coverage construction scheme corresponding to the target building is determined through 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.

The method is characterized in that the level actually generated indoors is measured, the geographic position is the most accurate, and in addition, 4G outdoor collection of the neighboring cells is adopted, so that coverage effect estimation after co-location construction can be performed on points where 5G is not yet constructed.

For some buildings with larger building areas, the outdoor level of the building can be counted, and the coverage area of the coverage level is calculated approximately by combining the partition condition of the wall body of the design drawing.
