As shown in FIG. 5, the method for predicting a CPE installation location in the embodiment of the present application includes the following steps.

Step 501: Determine at least one grid occupied by an outer surface of the same building in a set area of the three-dimensional electronic map.

It should be noted that the setting area may be an area in which a CPE needs to be installed in a preset three-dimensional electronic map, and the size of the specific setting area may be set as needed, and is not limited herein. For example, if a building that needs to install CPE is located in the Xiaohongmen area of Chaoyang District, Beijing, the setting area can be either Chaoyang District or Xiaohongmen District.

Step 502: Determine, for the first grid, a mounting angle of the CPE when the CPE is installed in the first position, and determine a signal receiving condition of the CPE when the CPE is installed at the mounting angle at the first position, and receive the signal as the first The signal coverage indicator of the grid; wherein the first location is a preset position in the first grid coverage area, and the first grid is any one of the at least one grid.

Step 503: Determine a candidate installation location of the CPE as a location of the grid in the at least one grid where the signal coverage indicator meets the preset condition in the three-dimensional electronic map.

It should be noted that the preset condition in the embodiment of the present application may be that the signal coverage index is ranked in the top N position when the signal coverage indicators are arranged in the order of high to low. The preset condition in the embodiment of the present application may also be a signal coverage indicator. The value of the threshold is greater than a certain threshold, and the size of the threshold may be set as required. The preset condition in the embodiment of the present application may also be other conditions that need to be set according to actual conditions. .

In step 502, there may be one or more base stations in which the signal covers the first grid in the set area of the three-dimensional electronic map. Optionally, when the base station in the set area of the three-dimensional electronic map covers the base station of the first grid, the base station serving as the CPE of the CPE when the base station is installed in the first position as the CPE provides services for the CPE, and determines The installation angle of the CPE when the CPE is installed in the first position, and the signal reception condition of the CPE when the CPE is installed at the installation angle at the first position; when the signal in the set area of the three-dimensional electronic map covers the first grid When there are multiple base stations, each base station is used as a base station serving the CPE when the CPE is installed in the first location, and determines the installation angle of the CPE when the CPE is installed in the first location, and determines to install in the first location. The signal reception condition of the CPE when the CPE is installed, and then the best signal reception condition (such as the maximum signal reception strength, the highest signal reception quality, the maximum signal rate, etc.) from the determined signal reception conditions of multiple CPEs. As the signal coverage indicator of the first grid, and the installation angle corresponding to the best signal reception condition of the signal reception conditions of multiple CPEs as the CPE in the first grid The installation angle of the location, the base station corresponding to the best signal reception situation of multiple CPEs is used as the base station of the serving cell of the CPE to provide services for the CPE, and the signal in the set area of the three-dimensional electronic map is covered to the first grid. The base station other than the base station of the serving cell of the CPE among the base stations of the cell serves as the base station of the neighboring cell.

For example, the base station that sets the signal in the area to cover the first grid has the base station 1 and the base station 2, and determines, for the base station 1 and the base station 2, the installation angle of installing the CPE in the first position as the CPE, and determining the first position. The signal receiving condition of the CPE when the CPE is installed at the installation angle, for example, the installation angle of the CPE when the CPE is installed at the first position determined by the base station 1 is (α1, β1), and the determined position at the first position is (α1, 11) When the CPE is installed, the CPE signal reception condition is A1, and the installation angle of the CPE when the CPE is installed at the first position determined by the base station 2 is (α2, β2), and the determined first position is (α2, β2) The signal reception condition of the CPE when the CPE is installed is A2. If A2>A1, the installation angle of the CPE is (α2, β2) when the CPE is installed in the first position for the first grid, and the first grid. The signal coverage indicator of the grid is A2.

Taking the example base station 1 as an example, determining the installation angle of the CPE at the first position of the first grid is the installation angle of the CPE, and determining the signal reception of the CPE when the CPE is installed at the installation angle at the first position of the first grid. The manner of the situation is specifically described, specifically including mode 1, mode two and mode three, wherein the first grid may be any one of at least one grid occupied by the outer surface of the same building.

method one:

If the transmission path between the first location and the second location is a non-line-of-sight (NLOS) propagation path, where the second location is the location where the base station 1 is located, and the CPE is installed in the first location The CPE can receive N adjustment angles of the electromagnetic wave signals from the base station 1 during the adjustment process within the adjustable range, and determine the angle of arrival when the electromagnetic wave signals reach the first position respectively at the N adjustment angles; and then adjust according to the N adjustments The angle of arrival of the electromagnetic wave signal at the angle to the first position determines the installation angle of the CPE when the CPE is installed at the first position, and N is a positive integer.

Optionally, the N adjustment angles can also be used to receive all adjustment angles of the electromagnetic wave signals from the base station 1 during the adjustment of the CPE in the adjustable range, and the N adjustment angles can also be used during the adjustment of the CPE within the adjustable range. All the adjustment angles of the electromagnetic wave signals received from the base station 1 are selected according to the set rules. The specific setting rules can be set according to actual needs, which is not limited. For example, an optional setting rule is that the N adjustment angles include a first adjustment angle and a second adjustment angle within an adjustable range of the CPE, and the CPE receives the maximum energy of the electromagnetic wave signal from the base station 1 when the CPE is at the first adjustment angle. The difference between the energy of the electromagnetic wave signal received from the base station 1 and the energy of the electromagnetic wave signal received from the base station 1 at the first adjustment angle when the CPE is at the second adjustment angle is within a preset range.

It should be noted that, in the embodiment of the present application, when the CPE is at the first adjustment angle, the maximum energy of the electromagnetic wave signal received from the base station 1 may also be referred to as the CPE at the first adjustment angle, and the electromagnetic wave signal sent by the base station 1 reaches the first. The energy of the diameter of the position is the largest, and the diameter is called the maximum energy path.

Optionally, the preset range is a consideration threshold of the multipath energy in the embodiment of the present application, and may be about 15 dB.

For example, the angle of arrival and the energy of the electromagnetic wave signal when the electromagnetic wave signal reaches the first position at the N adjustment angles are respectively (α0, β0, e0), (α1, β1, e1), (α2, β2, e2), ... (αn, βn, en), where n is the total number of electromagnetic wave signals reaching the first position at N adjustment angles, where (αi, βi) is used to indicate the angle of arrival, and ei is used to identify the energy of the electromagnetic wave signal, which is a linear value If the value of i is 0 to n, and e0>e1>e2...>en, the installation angle (α, β) of the CPE when the CPE is installed in the first position can be determined according to the following expression:

α=α0+angleA1×(e1/(e0+e1+...en))+....+angleAn×(en/(e0+e1+...en)), where angleAk is αk relative to α0 Angle offset, k is 0~n; β=β0+angleD1×(e1/(e0+e1+...en))+....+angleDn×(en/(e0+e1+.. .en)), angleDj is the angular offset of βj with respect to β0, and j is 0 to n.

For another example, in the embodiment of the present application, the installation angle (α, β) of the CPE when the CPE is installed in the first position may also be determined based on the following expression:

α=α0+α1×(e1/(e0+e1+...en))+....+αn×(en/(e0+e1+...en));

β=β0+β1×(e1/(e0+e1+...en))+....+βn×(en/(e0+e1+...en)).

In addition, in the embodiment of the present application, the installation angle (α, β) of the CPE when the CPE is installed in the first position may be determined based on other methods, which is not limited herein.

When determining the installation angle of the CPE when the CPE is installed in the first position based on the mode 1, optionally, the signal receiving condition of the CPE when the CPE is installed at the installation angle at the first position may be determined based on the following manner:

Since the base station covering the first grid in the first embodiment includes the base station 1 and the base station 2, and the base station 1 is used as the serving cell of the CPE, the base station 2 is the neighboring cell of the serving cell of the CPE:

For the base station 1 : according to the maximum antenna gain of the CPE, the electromagnetic wave signal emitted by the base station 1 reaches the signal energy in the adjustable range of the first grid at the first position, and the CPE when the CPE is installed in the first position Determining the actual antenna gain of the CPE when the CPE is installed at the first location based on the signal energy of the electromagnetic wave signal received from the base station 1 based on its own received scanning capability range during the adjustment range;

For the base station 2, determining that the actual antenna gain of the CPE when the CPE is installed at the first location is the antenna gain in the direction of the LOS propagation path between the first location and the location of the base station 2;

Then, according to the actual antenna gain of the CPE when the CPE is installed at the first location determined for the base station 1, and the actual antenna gain of the CPE when the CPE is installed at the first location determined for the base station 2, The signal reception status of the CPE when the CPE is installed at a mounting angle at a position.

For example, for base station 1, the actual antenna gain of the CPE when the CPE is installed at the first location can be determined based on:

Wherein, the CPE _gain is the actual antenna gain of the CPE when the CPE is installed in the first position;

The total energy of the signal energy of the electromagnetic wave signal from the base station 1 received by the CPE based on its own receiving scanning capability range during the adjustment of the CPE in the first position, and the electromagnetic _range is the electromagnetic wave emitted by the base station 1 The signal reaches the signal energy in the first position within the adjustable range of the first grid; CPEgain _max is the maximum antenna gain of the CPE.

Example,

Where α is the determined azimuth of the mounting angle of the CPE when the CPE is installed in the first position, and ANGLE_OFFSET is the angle value that the CPE can scan.

For example, when the CPE is installed at the installation angle at the first position, the signal reception condition of the CPE is a signal level, and after obtaining the actual antenna gain of the CPE for the base station 1 and the actual antenna gain of the CEP for the base station 2, For the base station 1, the actual antenna gain of the CPE is the antenna gain of the CPE to the serving cell. For the base station 2, the actual antenna gain of the CPE is the antenna gain of the CPE to the neighboring cell, and the transmit signals of the serving cell and the neighboring cell can be separately calculated. The power received by the signal after the power is transmitted to the CPE. The received power of the serving cell is the useful signal level, and the received power of the neighboring cell is the interference signal, so that the signal receiving quality, such as signal to interference plus noise ratio (SINR), can be calculated, and then based on the obtained signal. SINR, the obtained signal rate can be calculated by demodulation performance.

In the embodiment of the present application, optionally, determining at least one grid occupied by the outer surface of the same building may be in accordance with the flow diagram shown in FIG. 7 , specifically including the following steps.

In step 701, a grid block for representing a building in the set area is identified from the three-dimensional electronic map.

The grid block can be a solid figure as shown in FIG. 8. The specific size can be set according to the actual situation. For example, the grid block can be set to 2 meters x 2 meters x 2 meters, wherein the grid Each surface of the block is a grid, and the surface of each surface of the grid that corresponds to the outer surface of the building is the grid occupied by the outer surface of the building.

Since the 3D electronic map supports two data formats, one is a Vector format and the other is a Raster format, where the Vector format is a vector format. In this case, the Vector format needs to be converted into a raster format, and the Raster format is Raster format, after the data in the 3D electronic map is in the grid format, combined with the feature type information indicating the grid and the height information of the object in the Clutter layer, the grid block of the set area is filtered. A grid block used to represent a building. Where the feature type information of the building in the grid block is used to represent the building, and the height information of the object is greater than the threshold Height _Threshold , it is determined that the grid block is used to represent the grid block of the building.

For example, according to the connectivity of the grid block, the upper left corner of the set area starts to traverse the grid block used to represent the building, and for each grid block, it is determined whether the grid block has four directions in the east, west, north, and north directions. A grid block adjacent to the grid block for representing a building, if present, other grid blocks adjacent to the grid block representing the building are grouped into a group, Then proceed to the adjacent grid block of the grid block to make the same judgment, until the neighboring grid blocks around the determined grid block have the same judgment, then the grid blocks are occupied by the same building. Grid blocks, and mark the same building identifiers for these raster blocks.

Then, one of the grid blocks not marked with the building identifier in the set area is selected to repeat the above operation until all the grid blocks for representing the building in the set area are traversed.

Step 703: Determine at least one grid corresponding to an outer surface of the same building from each of the at least one grid block group.

Repeat the above operation until the move back to the starting point, the process ends. All of the marked grid blocks are at least one grid block corresponding to the outer surface of the same building, and then the grids in all of the marked grid blocks that represent the outer surface of the building are determined.

The grid block where the outer surface occupies the grid.

As shown in FIG. 10, when a user of a certain cell applies for the network service of the target package, the operator sends a request for opening the network service to the operator, and the operator applies for the opening of the network service request after receiving the application of the user. The network service is configured to determine the network that needs to meet the user's requirements, such as the signal rate. The installer can then install and debug the CPE based on the candidate installation location of the CPE determined in the embodiment of the present application to meet the user's network service. The demand has greatly improved the installation efficiency of installing CPE.

Specifically, if the user request in FIG. 10 is the signal rate in the network, when the CPE installation position is predicted by using the embodiment of the present application, the CPE signal receiving condition is CPE when the CPE is installed at the installation angle at the first position. Signal reception rate situation, etc., if the area where the cell where the user is located is the area 1 shown in FIG. 11, when the installation position of the CPE is predicted, the setting area is set to area 1, and then the CPE is installed. When the first position of the grid occupied by the outer surface of the building where the user is located (such as the longitude indicated by the dimension and the position indicated by the dimension), the downward peak rate of the CPE, wherein the descending peak rate is from high to low The position of the top 10% of the grid is shown in position 1 in Figure 10. The installer can perform the installation test from position 1 and then install the CPE, which improves the efficiency of CPE installation. It should be noted that the shade of the color occupied by the outer surface of the building where the user is located in FIG. 10 represents the downward peak rate of the CPE when the CPE is installed in the first position, and the darker the color in the area indicates that the CPE is installed. At this position, the downstream peak rate is greater.

This was verified in order to ensure the accuracy of the CPE mounting position and the installation angle of the CPE predicted by the embodiment of the present application.

The 3.5 GHz outdoor CPE installation test of a certain area is verified. The correct probability that the predicted CPE installation position satisfies the signal receiving condition is greater than or equal to 80%, and the predicted CPE installation angle deviation is about 50 degrees.

Where the verification of the correct probability of the installed location of the predicted CPE is as shown in FIG. 12, it is assumed that the area 1 is a building in a certain cell, wherein each triangle is defined as a household, and the triangle is measured by manual measurement. The vertices of the present invention are selected from the three vertices, and the vertices with the best signal reception condition are selected, and then the vertices with the best signal reception in the three vertices of the triangle are determined in the manner of the embodiment of the present application. The installation position of the predicted CPE is correct. Otherwise, the installation result of the CPE predicted by the embodiment of the present application is incorrect. In order to ensure the reliability of the verification, the signal reception is taken as an example.
