Features and exemplary embodiments of various aspects of the present invention will be described in detail below, and in order to make objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The base station for opposite-paging refers to two base stations with mutually covered transmitted signals. Specifically, if the signals from the base station a and the base station B both cover the same area, the base station a and the base station B are called as a base transceiver station. It should be noted that, if a certain area is simultaneously covered by a plurality of base stations, any two base stations in the plurality of base stations are base stations that are paired with each other. For example, if a certain area is covered by signals of base station a, base station B, and base station C at the same time, base station a and base station B are base station pairs, base station a and base station C are base station pairs, and base station B and base station C are base station pairs.
Base station interference is an important measurement factor of communication quality. When the two base stations are in opposite-direction, signals transmitted by the two base stations are easy to generate communication interference in a common coverage area. For example, when two interfere with a signal transmitted by a base station, call quality, dropped calls, handovers, immediate assignments and assignments, etc. may be affected.
Therefore, it is necessary to determine the base stations in a certain area. At the present stage, how to determine whether the tower worker who needs to be qualified for base station printing enters the station and goes up the tower for field investigation is carried out, and whether the base stations are printed in a mutual mode is judged by naked eyes. The method for manually judging whether the base stations are paired or not has the advantages of low accuracy, long judging period, time and labor waste, high labor cost and danger, so that a matching method for the base stations which are paired and can improve the defects is needed.
For better understanding of the present invention, the method, apparatus, device and medium for determining a base station according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be noted that these embodiments are not intended to limit the scope of the present disclosure.

and S120, determining candidate base stations for opposite hitting according to the geographical position information of the base stations to be matched.
And the geographical distance difference between the candidate base station and the base station to be matched is smaller than a preset distance threshold.
In some embodiments of the invention, the distance threshold r is used as the center of the base station to be matched1Determining an area W for the radius2Will be the region W2And determining other base stations except the base station to be matched as candidate opposite-hitting base stations. For example, if the area W2In addition to the base station to be matched, there are two base stations, namely, base station B and base station C, and then base station B and base station C can be used as candidate base stations for opposite-hit.
In some embodiments, the distance threshold r1May be an average inter-station spacing.
As an example, all base stations in a certain area including the base station to be matched may be determined, and an average value of distances between any two base stations in the area may be used as an average inter-station distance.
Illustratively, if there are 3 base stations in the area, base station a, base station B, and base station C, respectively. The average inter-station distance can be calculated by dividing the sum of the distance between the base station a and the base station B, the distance between the base station a and the base station C, and the distance between the base station B and the base station C by 3.
As another example, the base station to be matched may be taken as a center, a surrounding space of the base station to be matched is divided into a plurality of angle spaces according to angles, and a different weight value is assigned to each angle space. And respectively determining a base station closest to the base station to be matched and the distance between the closest base station and the base station to be matched in each angle space. And multiplying a plurality of distances between a plurality of closest base stations determined in a plurality of angle spaces and a base station to be matched with the weighted values respectively and then adding the weighted values to obtain an average inter-station distance.
Illustratively, if the antenna azimuth angle of the base station a is taken as 0 °, the [0 °, 120 °) is divided into a first angle space, the [120 °, 240 °) is divided into a second angle space, and the [240 °, 360 °) degree is divided into a third angle space. And dividing the weight w for the first angular space1Dividing the weight w for the second angular space2Is a third angleSpatial partitioning weight w3. If the base station closest to the base station to be matched in the first angle space is the base station B, the distance between the base station B and the base station to be matched is rB(ii) a The base station closest to the base station to be matched in the second angle space is a base station C, and the distance between the base station C and the base station to be matched is rC(ii) a The base station closest to the base station to be matched in the third angular space is a base station D, and the distance between the base station D and the base station to be matched is rD. Then, the average inter-station distance r1Satisfies formula (1):
r1＝rB×w1+rC×w2+rD×w3(1)
it should be noted that the method for calculating the average inter-station distance in the embodiment of the present invention is not limited to the above method, and may be other methods for calculating the average inter-station distance.

In some embodiments, the work parameter information table of the base station records work parameter information of all base stations in a certain area or work parameter information of all base stations belonging to a communication operator. The work parameter information includes geographical location information of each base station.
When the work parameter information of a certain base station needs to be utilized, the work parameter information of the base station can be directly read from the work parameter information table of the base station according to the serial number of the base station.
In some embodiments, the geographical location information of the base station may be stored within a Geographic Information System (GIS).
In some embodiments of the present invention, when the obtained geographic location information of the base station to be matched and the geographic location information of the candidate base station are GCJ-02 coordinates or offset coordinates of each platform, in order to obtain accurate geographic location information of the base station to be matched and accurate geographic location information of the candidate base station, so as to further improve the accuracy of the method for determining the serving base station, the method 100 for determining the serving base station further includes:
and converting the acquired geographical position information of the base station to be matched and the geographical position information of the candidate base station into Global Positioning System (GPS) coordinates through a coordinate deviation rectifying algorithm.
Note that the offset coordinates of each stage refer to: the map-like products provided by the different platforms have respective offset coordinate systems.
In some embodiments of the present invention, the base station to be matched may be selected according to the needs of a communication operator, or according to complaints or feedback of users on communication interference of the base station.
For example, when a communication operator needs to determine a base station or a base station in a certain area for various reasons, or determines the base station or the base station in a certain area for a certain base station according to complaints or feedback needs of users.
In an exemplary scenario, when a communication carrier receives a complaint from a user, and the complaint is that communication interference often occurs at a certain location, the communication carrier may determine the location as a location to be matched, determine a plurality of base stations based on geographical location information of the location to be matched, and further determine an opposite base station among the plurality of base stations.
In the embodiment of the present invention, when determining the base station to be matched, it is possible to directly determine a certain base station as the base station to be matched. For example, when the base station a needs to be determined as a base station to be matched, the base station a may be determined as the base station to be matched.
It is also possible to determine a location to be matched first, and then determine a base station to be matched according to the geographical location information of the location to be matched.

In some embodiments, the matching request to the base station may be sent by a communications operator or a user. For example, when a communication operator needs to determine a base station, or a user complaint or feedback about communication interference of the base station, a matching request for the base station may be sent.
As an example, when it is required to determine a base station for counterpointing signals covering a position a to be matched, the position a to be matched may be selected as a center and the distance r may be used2Are base stations within a certain range of the radius. For example, if the distances between the base station A, the base station B, the base station C and the base station D and the position a to be matched are not more than r2. Then, the base station a, the base station B, the base station C, and the base station D may be sequentially used as base stations to be matched to respectively search for the base stations of the base station a, the base station B, the base station C, and the base station D. Wherein, the distance r2May be a predetermined value, such as the distance r2Can be preset as the coverage radius of the base station.

In some embodiments, the subtended angle threshold may be a preset empirical value.
In some embodiments, the subtended angle threshold may be preset according to the horizontal lobe angle to the base station.
As one example, the subtended angle threshold may be the product of the horizontal lobe angle of the subtended base station and the attenuation coefficient. It should be noted that, in practical applications, the horizontal lobe angles of common base stations are 60 °, 65 °, and 90 °. When the horizontal lobe angles of the base stations are different, the subtending angle threshold is also changed accordingly. And if the horizontal lobe angles of the first base station and the second base station in the base station are different, taking the smaller horizontal lobe angle as the horizontal lobe angle of the base station. For example, if the horizontal lobe angle of the first base station is 65 ° and the horizontal lobe angle of the second base station is 90 °, the horizontal lobe angle of the first base station may be 65 ° with respect to the horizontal lobe angle of the base station.
Illustratively, if the horizontal lobe angle to the beat base station is 65 °, the beat angle threshold may be empirically taken to be 60 °. It should be noted that the antennas of the base station are divided into a directional antenna and an omnidirectional antenna in which a transmitted signal is uniformly radiated by 360 ° in the horizontal direction. The antennas of the base station in the above embodiments of the present invention are mainly directed to antennas. When the antenna of the first base station is an omni-directional antenna, the azimuth of the antenna of the first base station can be considered to be equal to the azimuth of the connection line. Accordingly, the first absolute difference value is zero. When the antenna of the second base station is an omni-directional antenna, the azimuth angle of the antenna of the second base station can be considered to be equal to the reverse angle of the azimuth angle of the connection line. Accordingly, the second absolute difference is zero.

Then, a traversal mode can be adopted, the plurality of base stations are respectively used as base stations to be matched, and the base stations to be matched are respectively determined.
Illustratively, if base station A, base station B and base station C are distantThe distances of the positions to be matched are all smaller than the distance r2Then, the base station a may be taken as the base station to be matched, then the S150 and S160 may be performed on the base station B to determine whether the base station B is the base station for the base station a, and then the S150 and S160 may be performed on the base station C to determine whether the base station C is the base station for the base station a.
