Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method and system for determining an antenna reverse connection.
Background
In the LTE (Long Term Evolution) network problem troubleshooting process, the problem of reverse connection of the cell antenna often exists. The antenna is reversely connected, no alarm is generated, and even no obvious index is reduced, so that the antenna is relatively hidden and is not easy to be found. However, the reverse connection of the cell antenna may cause an error in the cell coverage direction, thereby causing a disorder in relation with the neighboring cell, a delay in a handover point, frequency interference, and the like, and in a serious case, may cause a phenomenon such as a decrease in call quality, a call drop, and the like.
The existing technical scheme for judging the reverse connection of the antenna mainly comprises the following steps:
(1) and (4) observing whether the cell access and switching conditions are consistent with planning and working parameter information or not by testing the surrounding base station on site and combining related drive test software. However, the method can only perform a single-site detour test, and because the number of base stations in the whole network is very large, the station detour test for each site is unrealistic, which is not only inefficient, but also has little effect.
(2) And (6) index checking. Because the problems of low telephone traffic, frequency interference and the like can be caused by the reverse connection of the antenna, poor cells are found by screening relevant indexes, and the cells are checked station by station to check whether the problem of the reverse connection of the antenna exists. However, the method screens a large number of cells, and most of the problems are not caused by reverse antenna connection, and a problem that a large number of reverse antenna connection cells cannot be screened exists.
(3) Based on the statistical analysis of MR (Measurement Report) data, the problem of reverse antenna connection is discovered by comparing with the basic parameter information. Meanwhile, the coverage and quality problems of the cell are judged by combining information acquisition such as Reference Signal Receiving Power (RSRP). However, this approach is limited by the accuracy of the data and the MR function cannot be turned on for long periods of time, otherwise user perception is affected.
In summary, the conventional method for determining the reverse connection of the antenna is a passive search analysis, and generally has the problems of large workload, low efficiency and low accuracy.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 schematically illustrates a flowchart of a method for determining an antenna reverse connection according to an embodiment of the present invention, where the method includes:
step 101: and determining an azimuth angle vector of a connection line between the serving cell base station and each neighbor cell base station according to the position information of the serving cell base station and the neighbor cell base stations.
Step 102: and determining a main coverage azimuth vector of the serving cell according to the azimuth vector of the connection line of the serving cell base station and the neighboring cell base station.
Step 103: and if the included angle between the main coverage azimuth of the service cell and the azimuth vector of the service cell in the engineering parameter information is larger than a first threshold value, determining that the antenna of the service cell is reversely connected.
In the above step 101, first, according to the location information of the serving cell base station and the neighboring cell base stations, the distance between the serving cell base station and each neighboring cell base station is determined; and finally, weighting the angle vector between the connecting line of the serving cell base station and each neighboring cell base station and the positive north direction within a set time length, for example, according to the success frequency of switching all terminals in the serving cell to each neighboring cell within 24 hours, so as to obtain the azimuth angle vector between the connecting line of the serving cell base station and each neighboring cell base station.
Further, location information of the serving cell base station and the neighbor cell base stations may be obtained in a gateway database, for example, there are 100 serving cells under the whole network, if one of the serving cells corresponds to 6 neighbor cells, for the serving cell, longitude and latitude information of the serving cell base station and the 6 neighbor cell base stations may be obtained in the gateway database, and a distance between the serving cell base station and each neighbor cell base station in the 6 neighbor cells is calculated according to the longitude and latitude information of the serving cell base station and the 6 neighbor cell base stations; and converting the included angle between the connecting line of the serving cell base station and each neighboring cell base station in the 6 neighboring cells and the positive north direction into a unit vector, and using the unit vector as the included angle vector between the connecting line of the serving cell base station and each neighboring cell base station in the 6 neighboring cells and the positive north direction.
And acquiring the successful times of switching all terminals in the service cell to each adjacent cell in 6 adjacent cells within 24 hours in a network management database, and multiplying the vector of the included angle between the connecting line of the base station of the service cell and each adjacent cell base station in the 6 adjacent cells and the positive north direction by the successful times of switching all terminals in the service cell to the corresponding adjacent cells to obtain the azimuth angle vector of the connecting line of the base station of the service cell and each adjacent cell base station in the 6 adjacent cells.
In the embodiment of the present invention, for all serving cells in the entire network, the above method may be adopted to obtain the azimuth angle vector of the connection line between each serving cell base station and each corresponding neighboring cell base station, which is not described herein again.
In step 102, it is first necessary to determine an interfering cell in the neighboring cell, and then perform statistical summation on the azimuth vectors of the connection lines between the serving cell base station and all neighboring cell base stations except the interfering cell, as the main coverage azimuth vector of the serving cell.
Further, the interfering neighbor cell in the neighbor cell may be determined by part or all of the following ways: 1. taking a neighboring cell which belongs to the same base station coverage range as the service cell as an interference neighboring cell; 2. taking a neighboring cell in the indoor distribution cell as an interference neighboring cell; 3. taking the adjacent cell in the optical fiber repeater as an interference adjacent cell; 4. and determining the interference neighbor cell in the neighbor cell according to the azimuth angle vector of the connection line of the serving cell base station and each neighbor cell base station, the azimuth angle vector of the serving cell base station and the azimuth angle vector of each neighbor cell base station.
It should be noted that, for the interfering neighboring cells determined in the first three ways, since the interfering neighboring cells can be directly obtained according to the relationship between the serving cell and the neighboring cells, it is not necessary to calculate the azimuth vector of the connection line between the serving cell base station and the interfering neighboring cell base station determined in the three ways.
For the interfering neighbor cells determined in the fourth manner, a first included angle between the azimuth vector of the connection line between the serving cell base station and each neighbor cell base station and the azimuth vector of the serving cell base station can be determined according to the azimuth vector of the connection line between the serving cell base station and each neighbor cell base station and the azimuth vector of the serving cell base station; and determining a second included angle between the azimuth vector of the connecting line of the serving cell base station and each adjacent cell base station and the corresponding azimuth vector of each adjacent cell base station according to the azimuth vector of the connecting line of the serving cell base station and each adjacent cell base station and the corresponding azimuth vector of each adjacent cell base station. And if the first included angle is smaller than a second threshold value and the second included angle is smaller than a third threshold value, taking the corresponding adjacent cell as an interference adjacent cell. Specifically, the second threshold may be set to 90 °, and the third threshold may be set to 60 °.
In step 103, the azimuth vector of the serving cell may be obtained in the engineering parameter information, and then an included angle between the main coverage azimuth of the serving cell and the azimuth vector of the serving cell in the engineering parameter information is determined, and if the included angle is greater than the first threshold, it is determined that the antenna of the serving cell is connected in the reverse direction. The magnitude of the first threshold may be determined by experimental testing and engineering experience, for example the first threshold may be set to 125,
further, after determining that the antenna of a certain serving cell is reverse, the association information of the serving cell may be output, for example: the name of the serving cell, the location information of the serving cell base station, the main coverage azimuth vector of the serving cell, the number of times that all terminals in the serving cell switch to each neighboring cell, and the like.
The embodiment of the invention provides a method for determining reverse connection of an antenna, which comprises the steps of determining an azimuth angle vector of a connection line between a serving cell base station and each neighbor cell base station according to position information of the serving cell base station and the neighbor cell base stations; determining a main coverage azimuth vector of the serving cell according to the azimuth vector of the connection line of the serving cell base station and the neighboring cell base station; and if the included angle between the main coverage azimuth of the service cell and the azimuth vector of the service cell in the engineering parameter information is larger than a first threshold value, determining that the antenna of the service cell is reversely connected. The method for determining the reverse connection of the antenna provided by the embodiment of the invention can actively find the problem of the reverse connection of the cell antenna and improve the working efficiency and the accuracy of the system.
The following describes in detail the manner of determining the antenna reverse connection provided by the embodiment of the present invention by a specific calculation and analysis manner. First, a detailed description is given of a method for determining an azimuth vector of a connection line between a serving cell base station and a neighboring cell base station.
For example, the longitude and latitude of the serving cell base station is (S)j，Sw) The longitude and latitude of the adjacent base station is (N)j，Nw) The distance between two cell base stations with handover relation can be treated approximately as a two-dimensional plane. According to the triangle geometric relationship and the longitude and latitude information of the base stations of the two switching cells, the position relationship between the base station of the service cell and the base station of the adjacent cell is divided into four quadrants for classification processing, and the included angle alpha between the connecting line of the base station of the service cell and the base station of the ith adjacent cell and the due north direction is determinediAs shown in fig. 2, a schematic diagram of a position relationship between a serving cell base station and a neighboring cell base station according to an embodiment of the present invention is provided, where the serving cell base station is located at S, and the neighboring cell base stations are located at N1, N2, N3, and N4, respectively.
In the first case: sj<NjAnd S isw≤NwFor example, as shown in fig. 2, the neighboring cell node N1 is the angle vector between the connection line of the serving cell node and the neighboring cell node and the north direction
In the second case: sj≤NjAnd S isw>NwFor example, as shown in fig. 2, the neighboring cell node N2 is the angle vector between the connection line of the serving cell node and the neighboring cell node and the north direction
In the third case: sj>NjAnd S isw≥NwFor example, as shown in fig. 2, the neighboring cell node N3 is the angle vector between the connection line of the serving cell node and the neighboring cell node and the north direction
In a fourth case: sj≥NjAnd S isw<NwFor example, as shown in fig. 2, the neighboring cell node N4 is the angle vector between the connection line of the serving cell node and the neighboring cell node and the north direction
The dis1 is a distance between connection lines of the serving cell base station and the neighboring cell base station, and the dis2 is a projection of the serving cell base station and the neighboring cell base station in the due north direction. Specifically, dis1 is determined by the following equation (1), and dis2 is determined by equation (2).
Wherein D is the earth mean diameter. According to the spherical geometry algorithm, after the arc length of a unit angle on the standard earth sphere is obtained through the circumferential ratio, the distance between the connection lines of the service cell base station and the adjacent cell base station and the projection of the service cell base station and the adjacent cell base station in the positive north direction are calculated.
An included angle alpha between a connecting line of a service cell base station and the ith neighbor cell base station and the due north directioniConversion into unit vectors, i.e. alphaiNormalized to unit vector (sin α)i，cosαi) Obtaining the included angle vector (sin alpha) between the connecting line of the service cell base station and the ith adjacent cell base station and the due north directioni，cosαi)。
Obtaining the successful times of all terminals in the service cell to switch to each neighbor cell within 24 hours in a gateway database, and enabling the connection line of the base station of the service cell and the base station of the ith neighbor cell to form an included angle vector (sin alpha) in the positive north directioni，cosαi) Multiplying by the successful times M of all terminals in the service cell switching to the ith neighbor celli. Specifically, the azimuth angle of the connection line between the serving cell base station and each neighboring cell base station is determined by formula (2)Quantity betai。
βi＝(Mi×sinαi,Mi×cosαi) (3)
The following describes the determination of the primary coverage azimuth vector of the serving cell in detail.
Specifically, an interfering cell j in a neighboring cell needs to be determined, then, statistical summation is performed on azimuth vectors of connection lines between a serving cell base station and all neighboring cell base stations except the interfering neighboring cell, and the sum is used as a main coverage azimuth vector of the serving cell, and specifically, the main coverage azimuth vector of the serving cell is determined through a formula (4).
Wherein, the main coverage azimuth angle vector of the gamma service cell is k which is all the adjacent cells that the service cell can switch, and j which is the interference adjacent cell.
And finally, acquiring the azimuth angle vector of the serving cell according to the basic engineering parameter information number, calculating an included angle between the main coverage azimuth angle vector gamma of the serving cell and the azimuth angle vector of the serving cell, and if the included angle is larger than a set first threshold value of 125 degrees, judging that the antenna of the serving cell is reversely connected.
As shown in fig. 3a, a schematic diagram of a main coverage azimuth of a serving cell according to an embodiment of the present invention is shown, where the serving cell S has three switchable neighboring cells, N1, N2, and N3, and a shaded portion is a coverage area of the serving cell S. As can be seen from fig. 3a, the angle between the azimuth of the serving cell S and the calculated main coverage azimuth of the serving cell S is 25 °, which is within 125 ° of the first threshold, and therefore it is determined that the antenna direction of the serving cell S is not reversed.
As shown in fig. 3b, another schematic diagram of a main coverage azimuth of a serving cell according to an embodiment of the present invention is provided, where the serving cell S has four switchable neighbors, N1, N2, N3, and N4, and a shaded portion is a coverage area of the serving cell S and the neighboring cell N4. As shown in fig. 3b, the angle between the azimuth of the serving cell S and the calculated main coverage azimuth of the serving cell S is 175 °, which is greater than the first threshold value 125 °, so that it is determined that the antenna direction of the serving cell S is reversed. Just because the antenna direction of the serving cell S is connected in the reverse direction, the ratio of the successful times of switching of the neighboring cell N4 is relatively large, that is, the main coverage azimuth vector of the serving cell S is biased to the neighboring cell N4, so that the included angle between the main coverage azimuth vector of the serving cell S and the azimuth vector of the serving cell S is not within the first threshold range.
As shown in fig. 3c, a schematic diagram of a main coverage azimuth of another serving cell according to an embodiment of the present invention is provided, where the serving cell S has a switchable neighboring cell N, and a shaded portion is a coverage area of the serving cell S and the neighboring cell N. Although the included angle between the serving cell S main coverage azimuth vector and the serving cell S azimuth vector is 180 °, which is not within the first threshold range, since the serving cell S is within the coverage of the neighboring cell N, this situation belongs to normal handover, and therefore it is necessary to determine the interfering cell in the neighboring cell before calculating the serving cell main coverage azimuth.
The following describes in detail the determination method of the interference cell calculation.
Specifically, the determination of the interference neighboring cell is divided into four cases.
In the first case: and taking the adjacent cell which belongs to the same base station coverage range as the service cell as the interference adjacent cell.
In the second case: and taking the adjacent cell in the indoor distribution cell as an interference adjacent cell.
In the third case: and taking the adjacent cell in the optical fiber repeater as an interference adjacent cell.
It should be noted that, for the interfering neighboring cell j determined in the first three ways, since the relationship between the serving cell and the neighboring cell is directly obtained in the gateway database, it is not necessary to calculate the azimuth angle vector of the connection line between the serving cell base station and the interfering neighboring cell base station determined in the three ways. After the interference neighbor j is determined, the azimuth vectors of the connection lines of the serving cell base station and all neighbor base stations except the interference neighbor j need to be counted and summed according to the main coverage azimuth vector calculation formula (4) of the serving cell.
