If the communication signal strength of a plurality of continuous sub-areas in the area to be planned is weak, the construction of a 5G base station is required to be considered in the area to be planned so as to enhance the communication signal strength. However, since the 4G communication signal information does not include the geographical location information of the user terminal, and the information related to the user terminal in the 4G communication signal information cannot be directly located at the geographical location of the user terminal, the 4G communication signal information needs to be matched with the geographical location of each sub-area of the area to be planned, and the 4G communication signal information is located at the corresponding sub-area, so as to obtain the 4G communication signal information of each sub-area.

Specifically, a numerical relationship between the 4G communication signal received power and the 5G communication signal received power is obtained through theoretical analysis, and the known 4G communication signal received power is converted into the 5G communication signal received power according to the numerical relationship. Further, the 4G communication signal reception power in the 4G communication signal information located in each sub-region in S206 is replaced by the 5G communication signal reception power, so as to obtain the 5G communication signal information of each sub-region.

The second geographical position of the base station to be planned is a place which simultaneously meets the requirements of high communication value and weak target communication signals, and the place is used as the priority of the target geographical position of the base station to be planned and is only second to the available 4G base station address. That is, in addition to the available site of the 4G base station, it is preferable to construct the 5G base station at a site satisfying both high communication value and weak target communication signal.

The preset coverage radius refers to the inter-station distance of the 5G base station. The inter-station distances of the 5G base stations established in different scenes are different, and the inter-station distances of the different scenes are determined according to current 5G technical research analysis and test data.

In one embodiment, the inter-site distance corresponding to dense urban areas may be 200-300 meters, the inter-site distance corresponding to general urban areas may be 300-400 meters, the inter-site distance corresponding to suburbs may be 400-500 meters, and the inter-site distance corresponding to rural areas may be 500-700 meters.

Specifically, when the 5G communication signal received power of a preset number of consecutive sub-regions is less than or equal to the preset communication signal received power threshold, it indicates that the 5G communication signal within the preset number of consecutive sub-regions is weak. Taking the geometric centers of the sub-regions with the continuous preset number as initial planning sites, and counting the number of the sub-regions of which the intra-circle communication reference information is larger than or equal to a first preset threshold and the target communication signal receiving power is smaller than or equal to a preset communication signal receiving power threshold, wherein the intra-circle communication reference information is determined by taking the initial planning sites as the circle center and the radius as a preset covering radius.

And taking the geographical position of the initial planning station as a candidate second geographical position of the base station to be planned. Further, whether the distance between the adjacent candidate second geographic positions meets the station distance requirement of the 5G base station is judged, and the candidate second geographic positions meeting the station distance requirement of the 5G base station are used as target geographic positions of the 5G base station.

In one embodiment, there is a clear requirement for the signal strength of coverage in the 5G networking requirements of mobile, telecommunication, and connectivity, the 5G communication signal received power is less than or equal to-110 dBm, which is a weak coverage point, and when the 5G communication signal received power is less than or equal to-110 dBm within a continuous 100 meter range, it is determined as a weak coverage area. Assuming a 10m by 10m grid as a sub-area, the preset coverage radius is 300 meters. When the received power of 5G communication signals of 10 continuous grids is less than or equal to-110 dBm, the 10 grids form a weak coverage area. Since the available 4G base station site plans the 5G base station to be the highest priority, the available 4G base station site is not considered for weak coverage areas within 300 meters. And if a weak coverage area exists in a range of 300 meters out of the range of 300 meters of the available 4G base station address, acquiring the longitude and latitude of a grid at the center position of the weak coverage area as a first planning station.

When the communication reference information of 25% of grids in the coverage range is greater than or equal to 70 minutes, and the 5G communication signal receiving power of 30% of grids is less than or equal to-110 dBm, the coverage area is a high communication value and weak signal area. At this time, the first planned station may be a candidate station for the 5G base station.

In the above embodiment, the geographical position of the first planning station that satisfies the weak signal and the high communication value is used as the candidate second geographical position of the base station to be planned, and the 5G base station is planned and constructed at the geographical position, so that the 5G communication signal can be enhanced, and the mass communication requirements of a large number of users can be satisfied.

The station spacing threshold refers to the maximum value of the station spacing of the 5G base station. The maximum value of the station spacing of the 5G base stations established in different scenes is different, and the maximum value of the station spacing of the different scenes is determined according to research, analysis and test data of the current 5G technology.

In one embodiment, the inter-site distance threshold for dense urban areas may be 300 meters, the inter-site distance threshold for general urban areas may be 400 meters, the inter-site distance threshold for suburban areas may be 500 meters, and the inter-site distance threshold for rural areas may be 700 meters.

Specifically, when the distance between two adjacent candidate second geographic positions of the 5G base station is greater than the distance threshold between the two adjacent candidate second geographic positions of the 5G base station, it is indicated that the two adjacent candidate second geographic positions are unreasonable. Therefore, the candidate second geographic location is to be planned continuously. And taking the geometric center of the distance between the two adjacent candidate second geographic positions as a new initial planning station, and counting the number of sub-areas of which the circular in-coverage communication reference information is greater than or equal to a first preset threshold and the target communication signal receiving power is less than or equal to a preset communication signal receiving power threshold, wherein the new initial planning station is taken as the center of a circle and the radius is determined as a preset coverage radius. When the number of the sub-areas of which the communication reference information is greater than or equal to the first preset threshold is greater than or equal to the second preset threshold, and the number of the sub-areas of which the target communication signal received power is less than or equal to the preset communication signal received power threshold is greater than or equal to the third preset threshold, it indicates that the communication value of the area around the new initial planning station is high and the communication signal is weak. And taking the geographical position of the new initial planning station as a candidate second geographical position of the base station to be planned.

In the foregoing embodiment, when the distance between two adjacent candidate second geographic positions of the 5G base station is greater than the inter-station distance threshold, if the 5G base station is built in the two adjacent candidate second geographic positions, the 5G communication signal in a partial area between the two adjacent candidate second geographic positions is weak. Therefore, when the distance between two adjacent candidate second geographic positions of the 5G base station is greater than the distance threshold between the stations, the new candidate second geographic position of the 5G base station is determined according to the distance between the two adjacent candidate second geographic positions. In this way, planning continues between unreasonable sites to ensure that the 5G communication signal strength in the area to be planned is large and uniform.

In one embodiment, the method further comprises:

and S606, when the distance between two adjacent candidate second geographic positions of the base station to be planned is less than or equal to the distance threshold between the stations, taking the candidate second geographic positions as the second geographic positions of the base station to be planned.

Specifically, when the distances between all the adjacent candidate second geographic positions are less than or equal to the distance threshold, all the adjacent candidate second geographic positions are indicated to be reasonable. Therefore, all the neighboring candidate second geographical locations are taken as the sites of the 5G base stations. The planning priority of the site is next to the available 4G base station site.

In one embodiment, as shown in fig. 7, the method further comprises:

s702, all sub-areas within the preset coverage radius of the target geographic position are obtained.

Specifically, a coverage area may be determined according to a preset coverage radius with the target geographic location as a center, where the coverage area includes a plurality of sub-areas. For example, assume a grid of 10m by 10m in size for each sub-region. And with the target geographic position of the 5G base station as a center of a circle and 300 meters as a preset coverage radius, determining a circle according to the center of the circle and the radius, wherein the circle comprises about 2826 grids.

The antenna panel installation angle of each serving cell needs to be preferentially directed to a high-value area so as to meet the communication requirements of users in the high-value area. The high-value region refers to a region having a value rank of 2 or more, that is, a region in which the communication reference information is 70 points or more. Therefore, the number of sub-regions with a value rank greater than or equal to 2 within 120 degrees is counted every 1 degree from true north 0 degrees. And counting 120 times for each service cell, and selecting the central point of the angle range with the maximum number of the sub-areas with the value grade greater than or equal to 2 in the 120 times as the antenna panel installation angle of the service cell corresponding to the 5G base station. And after the antenna panel installation angle of the first service cell is determined, determining the antenna panel installation angle of the second service cell by using the antenna panel installation angle of the first service cell as a starting point according to the same method. And after the antenna panel installation angle of the second service cell is determined, determining the antenna panel installation angle of a third service cell by using the antenna panel installation angle of the second service cell as a starting point according to the same method.

For example, assuming a grid with 10m x 10m size for each sub-region, 300 meters is the preset coverage radius. Counting the number of grids with the value grade being more than or equal to 2 within the range of 0-120 degrees for the first time from 0 degree due to the north, counting the number of grids with the value grade being more than or equal to 2 within the range of 1-121 degrees for the second time, and so on, and counting 120 times. Assuming that the number of grids having a value level greater than or equal to 2 is the largest in the range of 30 to 150 degrees, the central point of the range of 30 to 150 degrees, i.e., 90 degrees, is used as the antenna panel installation angle of the first serving cell. Then, counting the number of grids with the value grade being greater than or equal to 2 within the range of 90-210 degrees for the first time, counting the number of grids with the value grade being greater than or equal to 2 within the range of 91-211 degrees for the second time, and so on, counting 120 times, and determining the antenna panel installation angle of the second service cell according to the data of the 120 times. The antenna panel installation angle of the third serving cell is determined in the same manner.

In the above embodiment, the number of the sub-areas in which the communication reference information is greater than or equal to the fourth preset threshold within the preset angle range is counted every unit angle by acquiring all the sub-areas within the preset coverage radius of the target geographic position, and the antenna panel installation angle of the serving cell of the target base station corresponding to the target geographic position is determined according to the counting result. The antenna panel installation angle of the serving cell of the target base station can be pointed to the high-value area so as to meet the communication requirement of users in the high-value area.
