The first preset value, the second preset value and the third preset value can be set according to actual conditions.
In this embodiment, the display processing module 16 includes a layer processing unit, and the layer processing unit is configured to connect the sampling point with the primary coverage and the neighboring coverage by a line, and locate a corresponding cell identifier of the primary coverage base station and a corresponding cell identifier of the neighboring coverage base station.

Referring to fig. 2, the present embodiment provides a method for optimizing coverage of radio frequency signals of an outdoor macro base station, including the following steps:
step S101: and acquiring information of signal coverage sampling points in the signal optimization area through the drive test equipment 10, wherein the information of the sampling points comprises one or more of position information of the sampling points, base station ID, SINR of the main coverage signal, PCI of the local area, PCI field intensity of the local area, PCI of the adjacent area and PCI field intensity of the adjacent area.
Step S103: and rasterizing the sampling points to enable the distance between two adjacent sampling points to accord with a preset interval range. The preset interval range is 1 meter, for example, two adjacent sampling points are at least 1 meter apart, and sampling points less than 1 meter need to be discarded.
Step S105: and searching the corresponding base station cell identification (CellID) through the local area PCI and the adjacent area PCI.
Step S107: and counting the information of the sampling points according to the field intensity difference, the main coverage SINR threshold and the weak coverage SINR threshold to obtain statistical information, wherein the statistical information comprises the times of the main coverage identity and the adjacent coverage identity in the signal optimization area.
Step S109: and aiming at the signal optimization area with the ratio of the number of times of the neighbor cell coverage identity to the number of times of the main coverage identity exceeding a first preset value, representing the main coverage and neighbor cell coverage information corresponding to the sampling point.
Step S111: the signal coverage of the signal optimization region is optimized according to the result shown in step S109.
Step S109 includes outputting the layer file, connecting the sampling point with the primary coverage and the neighboring coverage by lines, and locating the corresponding cell id of the primary coverage base station and the cell id of the neighboring coverage base station. The lines of the sampling points and the main coverage and the lines of the sampling points and the neighboring coverage can be distinguished by different colors, so that the optimized personnel can watch the lines conveniently.
In step S107, the statistical information further includes information of sampling points in the signal optimization region where the interference of the modulo three MO3 exists, information of sampling points in the signal optimization region where the signal switching speed is slower than the second preset value, a cell identifier of the primary coverage base station and a cell identifier of the neighboring coverage base station, where the coverage radius in the signal optimization region is greater than the third preset value.
In step S109, the method further includes representing a local PCI and an adjacent PCI corresponding to a sampling point where the modulo three (MO3) interference occurs, representing a switching parameter of a sampling point whose signal switching speed is slower than a second preset value, and representing a cell identifier of the primary coverage base station and a cell identifier of the adjacent coverage base station whose coverage radius is greater than a third preset value, as shown in fig. 3. Therefore, the signal coverage optimization personnel can visually find out where the modulo three (MO3) interference exists in the signal optimization area, where the adjacent area is stronger than the main coverage, where the excessive signal overlapping coverage exists, and where the excessive signal overlapping coverage phenomenon exists as the adjacent area, so that the signal coverage optimization personnel can optimize the signal coverage of the signal optimization area conveniently, and the workload of the signal coverage optimization personnel is reduced.
In step S101, the information of the sampling point includes a minimum level value of the PCI of the neighboring cell. In step S107, the information of the sampling points is counted, and the influence of the PCI of the neighboring cell whose minimum level value is smaller than the fourth preset value is ignored.
The first preset value, the second preset value, the third preset value and the fourth preset value can be set according to actual conditions.
Fig. 3, fig. 4, fig. 5 and fig. 6 are an example of the presentation results in step S109 of the present invention, in which the connection lines between the primary coverage cell, the general neighboring cell, the neighboring cell stronger than the primary coverage, and the neighboring cell mainly covered with modulo three (MO3) interference and the sampling point can be distinguished by different colors, so as to facilitate the viewing of the signal coverage optimizer.
In fig. 3, it can be seen that the main coverage is mainly covered by the mary buildings 1, 3 cells, for example, for the problem of optimizing the area for the signal of the intermediate drive test. The adjacent cells are four cells of Xiang Mi lake No. 1, Jing Tian West, Jing Tian Ding Meng Yuan and Futian cha Gong besides the two cells are adjacent cells. That is, the problem point location can receive 6 cell signals at the same time, and the field strength values of the cells are within 10dB of the main coverage cell.
From the overall coverage, 1 cell in the west of the scenic field, 3 cells in the dream garden of the scenic field, 3 cells in the tea palace of the Futian, and 1 cell under the scenic field are not mainly used in the signal optimization area, and the pitch angle can be reduced to reduce the negative influence on the SINR (signal to interference plus noise ratio) finger of the problem point.
In addition, the coverage lobe of the 3-cell of the fragrant mansion is too large, close to 180 degrees, and the problem of too wide coverage range of the fragrant mansion needs to be solved by replacing the antenna or adjusting the azimuth angle of the antenna.
For the over-coverage situation, for example, as shown in fig. 4, the SINR problem point in the signal optimization area in the oval circle is only about 100 meters away from the rainfield building, but due to a few obstructions, the signal is not strong enough, so that the field intensity of the field beyond 1.1 km is affected, and the field intensity of the field 1 cell at the problem point even exceeds the field intensity of the service area. As can be seen from fig. 4, the main coverage distance of the 1 st cell is close to the 74 th base station in the northern lotus flower cell, and the problem that the coverage of the area is needed to be solved when the area appears beyond 1.1 km many times with the identity of the adjacent cell.
The above-mentioned handover coverage problem, as shown in fig. 5, besides the scenic access base station handover coverage, there is also a problem that the lotus north cell 74 and 2 cell back wave lobes affect the main coverage of the rain field cell 2, and these two cells have the modulo three (MO3) interference. In combination with the situation that the signal optimization area has no main lotus north cell 74 or 2 cells, the coverage area of the cell needs to be adjusted.
For the statistics of the occupied cells of the signal optimization region, for example, as shown in fig. 6, it can be seen that the first village 63 of Futian Meilin-3 (primary coverage 6 times, neighbor identity 53 times) and the first village 13 of Meilin-1 (primary coverage 2 times, neighbor identity 22 times). In order to guarantee the signal quality of the current area, the power of the base station which has a lot of times of occurrence as the identity of the adjacent area can be reduced if necessary, even temporarily closed, and the base station is adjusted to be in a normal state after the guarantee is finished.
Through the representation result, the signal coverage optimization personnel can visually know the position of the problem point in the signal optimization area and the problem point, and can provide a reasonable and effective optimization scheme according to the representation result so as to optimize the signal coverage of the signal optimization area, thereby greatly reducing the workload of the signal coverage optimization personnel.
From the results shown in fig. 3, 4, and 6, the statistical tables of the signal optimization region cell occupancy in fig. 3, 4, and 6 are as follows:
the above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
