Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described below are only for the purpose of illustrating and explaining the present invention, and are not to be construed as limiting the present invention.

The first embodiment of the antenna feeder system detection method provided by the present invention is applied to a base station, where the base station includes at least one cell, preferably three cells, and each cell obtains a certain signal coverage area through configuration of a corresponding antenna feeder system.

Fig. 1 is a schematic flow chart of a first embodiment of a detection method for an antenna feeder system according to the present invention; as shown in fig. 1, the method includes:

step 101: acquiring at least one piece of first information of at least one terminal, wherein the first information is used for representing the geographical position information of the terminal, and the terminal is a terminal residing in a target cell;

the communication entity performing this step is a base station. The terminal selects one of the at least one cell as a primary serving cell, for example, selects cell 1 as the primary serving cell from cell 1, cell 2 and cell 3. Along with the movement of the terminal, the terminal can move from one cell to another cell and also move from one position to another position in the same cell, the terminal can report the current geographical position information of the terminal to the base station periodically, for example, reporting every 5min or 150s, and the base station receives the information reported by the terminal. The terminal can collect the geographic position information through a built-in Global Positioning System (GPS) module, an auxiliary global positioning system (A-GPS) module and/or a Geographic Information System (GIS) module and report the geographic position information after the collection is finished. Because the a-GPS module is faster and more accurate in positioning, the terminal preferably performs positioning of the geographical location through the a-GPS module, so that the subsequent base station can more accurately position the coverage center area of the target cell based on the geographical location.

In practical applications, since the terminal reports a Measurement Report (MR) to the base station periodically, the measurement report may include at least the following: the signal strength of a cell (main serving cell) where the terminal currently resides, the current transmit power of the terminal, and the signal strength of at least one neighboring cell (neighbor cell) of the main serving cell. According to the scheme, a content item is added in the MR, the geographic position information of the terminal is used as the content of the content item, and the content is reported regularly along with other content in the MR. It is worth noting that: as the terminal moves, the main serving cell of the terminal may change, and the target cell may specifically be the main serving cell of the terminal, or may also be a cell adjacent to the main serving cell, that is, a neighboring cell.

The number of cells under a base station is usually greater than or equal to 1, the location of a terminal is usually changed many times, an MR received by the base station is an MR in which the terminal resides under each cell of the base station, when the base station knows which primary serving cell a certain terminal currently resides in, the base station should select, from among the numerous MRs, an MR reported by the terminal while residing under the primary serving cell, and read each geographical location information in which the terminal resides when residing in the primary serving cell from the selected MR.

Step 102: determining a coverage center area of the target cell according to the at least one piece of first information;

the communication entity performing this step is a base station. The base station determines a signal coverage center area of a main service cell according to at least one piece of geographical position information reported by the terminal when the terminal resides in the main service cell.

Step 103: acquiring first data according to the coverage center area of the target cell, wherein the first data is used for representing the distance between the reference point of the target cell and the coverage center area and/or the angle required to be rotated when the reference direction of the target cell is rotated to the reference direction of the coverage center area;

the communication entity performing this step is a base station. And the base station acquires the distance between the reference point of the main service cell where the terminal resides and the coverage center area and/or the angle required to be rotated when the reference direction of the main service cell is rotated to the reference direction of the coverage center area. In the process of configuring the antenna feeder system of the target cell, the reference point and the reference direction are set. For example, the reference direction of the target cell is configured to be the southeast direction, the northwest direction, or the true east/south/west/north direction of the cell, or may be the southeast direction, the northwest direction, or the true east/south/west/north direction of the base station to which the cell belongs; the position of 300m, for example, along the base station direction of the target cell and within a certain range from the base station may be the reference point of the target cell, or the center position of the target cell may be the base station. In the scheme, the reference point and the reference position have a reference function, the reference point and the reference position are not specifically limited, and the position and the direction which can have the reference function can be both used as the reference point and the reference direction.

Step 104: judging whether the first data is in a first preset range or not, and generating a first judgment result;

the communication entity performing this step is a base station. The base station judges whether the first data is located in a first preset range.

Step 105: and determining whether the antenna feeder system of the target cell is abnormal or not according to the first judgment result.

The communication entity performing this step is a base station. And the base station determines whether the antenna feeder system of the target cell is abnormal or not according to the judgment result.

In a preferred embodiment of the present invention, step 105 further comprises:

when the first judgment result represents that the first data is not located in a first preset range, determining that an antenna feed system of the cell is abnormal; and when the first judgment result represents that the first data is located in a first preset range, determining that the antenna feeder system of the cell is not abnormal.

The first preset range is a value range of a distance between a reference point of a target cell and a coverage center area when a preset antenna feeder system is normal and/or a value range of an angle required to be rotated when the reference direction of the target cell is turned to the reference direction of the coverage center area, the antenna feeder system of the target cell can be determined to be abnormal when the first data is judged not to be located in the normal value range, and the antenna feeder system of the target cell can be determined to be normal when the first data is judged to be located in the normal value range.

Therefore, in the scheme, the coverage center area of the target cell is determined according to the geographical position information of each terminal residing in the target cell, the first data is obtained according to the coverage center area, and whether the antenna feeder system of the target cell is abnormal or not is determined by judging whether the first data is located in the first preset range or not. Compared with the existing mode of determining whether the antenna feeder system is abnormal or not by adopting a manual checking mode, the scheme realizes the automatic detection of whether the antenna feeder system is abnormal or not, data based on the process of detecting whether the antenna feeder system is abnormal or not, such as data in the network operation process of each geographic position where the terminal is located, can realize the automatic detection of the antenna feeder system according to the data in the network operation process, can know whether the antenna feeder system is abnormal or not without the outdoor checking operation of operation and maintenance personnel, can greatly reduce manpower and material resources, can effectively improve the detection accuracy and avoid the problem of low accuracy caused by manually checking the abnormality of the antenna feeder system.

The second embodiment of the antenna feeder system detection method provided by the present invention is applied to a base station, where the base station includes at least one cell, preferably three cells, and each cell obtains a certain signal coverage area through configuration of a corresponding antenna feeder system.

Fig. 2 is a schematic flow chart illustrating the implementation of a second embodiment of the antenna feeder system detection method provided by the present invention; as shown in fig. 2, the method includes:

step 201: acquiring at least one piece of first information of at least one terminal, wherein the first information is used for representing the geographical position information of the terminal, and the terminal is a terminal residing in a target cell;

the communication entity performing this step is a base station. The terminal selects one of the at least one cell as a primary serving cell, for example, selects cell 1 as the primary serving cell from cell 1, cell 2 and cell 3. Along with the movement of the terminal, the terminal can move from one cell to another cell and also move from one position to another position in the same cell, and the terminal can report the current geographical position information of the terminal to the base station periodically, for example, once every 5min or 150 s. The terminal can collect the geographic position information through a built-in Global Positioning System (GPS) module, an auxiliary global positioning system (A-GPS) module and/or a Geographic Information System (GIS) module and report the geographic position information after the collection is finished. Because the a-GPS module is more accurate in positioning, the terminal preferably performs positioning of the geographical location through the a-GPS module, so that the subsequent base station can more accurately position the coverage center area of the target cell based on the geographical location.

Because the number of cells under a base station is usually greater than or equal to 1, the location of a terminal is usually changed many times, an MR received by the base station is an MR in which the terminal resides under each cell of the base station, and when the base station knows which primary serving cell a certain terminal currently resides in, the base station should select, from among the numerous MRs, an MR reported by the terminal when the terminal resides under the primary serving cell, and read, from the selected MR, each geographical location information in which the terminal resides in the primary serving cell.

Step 202: clustering/converging the at least one geographic position information to obtain first longitude and latitude information; determining an area corresponding to the first longitude and latitude information as the coverage center area;

the communication entity performing this step is a base station. The base station carries out clustering/convergence processing on at least one geographical position information reported when the terminal resides in the target cell to obtain longitude and latitude information (first longitude and latitude information), and determines that an area corresponding to the longitude and latitude information is a signal coverage center area of the target cell.

Wherein the clustering/aggregating the at least one geographical location information to obtain the first longitude and latitude information includes: calling a geographical grid table, wherein the geographical grid table comprises two or more grid areas, and mapping each geographical position information in the at least one geographical position information to one grid area in the geographical grid table; screening a target grid area, wherein the number of the geographic position information mapped in the grid area is greater than or equal to a first threshold value; acquiring all geographic position information mapped in a target grid area to obtain at least two pieces of target geographic position information; determining the first longitude and latitude information according to the at least two pieces of target geographic position information. Here, the geographical grid table includes at least two grid areas, each grid area corresponds to certain longitude and latitude information, the base station maps each geographical location (the geographical location is represented by longitude and latitude) reported by the terminal when residing in the target cell to the corresponding grid area, screens out the grid areas with the quantity of the mapped longitude and latitude information being greater than or equal to a first threshold value from the at least two grid areas and regards as the target grid area, and calculates the longitude and latitude (first longitude and latitude information) corresponding to the coverage center area of the target cell according to all the geographical location information (target geographical location information) mapped in the target grid area.

Here, the determining the first longitude and latitude information according to the at least two target geographical location information includes: determining longitude and latitude information corresponding to each target geographic position in the at least two target geographic positions to obtain at least two longitude and latitude information; and performing (arithmetic) average operation on the at least two longitude and latitude information, performing weighted average operation on the at least two longitude and latitude information, or performing root mean square average operation on the at least two longitude and latitude information to obtain the first longitude and latitude information. Here, the base station collects longitude and latitude information corresponding to all target geographic locations, and performs (arithmetic) average operation, or performs weighted average operation, or performs root mean square average operation on all the collected longitude and latitude information, so as to obtain longitude and latitude (first longitude and latitude information) corresponding to the coverage center area of the target cell.

Step 202 is determining a further description of the coverage center area of the target cell according to the at least one first information as in the present scheme.

Step 203: acquiring first data according to the coverage center area of the target cell, wherein the first data is used for representing the distance between the reference point of the target cell and the coverage center area and/or the angle required to be rotated when the reference direction of the target cell is rotated to the reference direction of the coverage center area;

the communication entity performing this step is a base station. And the base station acquires the distance between the reference point of the target cell and the coverage center area and/or the angle required to be rotated when the reference direction of the target cell is rotated to the reference direction of the coverage center area. In the process of configuring the antenna feeder system of the target cell, the reference point and the reference direction are set. For example, the reference direction of the target cell is configured to be the southeast direction, the northwest direction, or the true east/south/west/north direction of the cell, or may be the southeast direction, the northwest direction, or the true east/south/west/north direction of the base station to which the cell belongs; the position of 300m, for example, along the base station direction of the target cell and within a certain range from the base station may be the reference point of the target cell, or the center position of the target cell may be the base station. In the scheme, the reference point and the reference position have a reference function, the reference point and the reference position are not specifically limited, and the position and the direction which can have the reference function can be both used as the reference point and the reference direction.

Step 204: judging whether the first data is in a first preset range or not, and generating a first judgment result;

Step 205: and determining whether the antenna feeder system of the target cell is abnormal or not according to the first judgment result.

In a preferred embodiment of the present invention, step 205 further comprises:

Therefore, in the above scheme, all geographical location information where the base station terminal resides in the target cell is obtained, the geographical location information is clustered/aggregated to obtain a coverage center area of the target cell, first data is obtained according to the coverage center area, and whether the antenna feeder system of the target cell is abnormal or not is determined by judging whether the first data is located in a first preset range or not. Compared with the existing mode of determining whether the antenna feeder system is abnormal or not by adopting a manual checking mode, the scheme realizes the automatic detection of whether the antenna feeder system is abnormal or not, data based on the process of detecting whether the antenna feeder system is abnormal or not, such as data in the network operation process of each geographic position where the terminal is located, can realize the automatic detection of the antenna feeder system according to the data in the network operation process, can know whether the antenna feeder system is abnormal or not without the outdoor checking operation of operation and maintenance personnel, can greatly reduce manpower and material resources, can effectively improve the detection accuracy and avoid the problem of low accuracy caused by manually checking the abnormality of the antenna feeder system.

The present solution will be further described with reference to the application scenarios shown in fig. 3(a) and (b).

In fig. 3(a), (b), it is assumed that the base station has three cells: cell 1, cell 2, and cell 3 (considering space restriction cell 3 is not shown), taking the primary serving cell as cell 1 as an example. When each terminal enters a signal area covered by the base station, the terminal moves among the three cells and/or moves at different positions in the same cell, before each terminal moving in a signal range covered by the base station reports an MR to the base station regularly, the built-in GPS module, an A-GPS module and/or a GIS module collects the current geographic position of the terminal, and the collected geographic position is used as a content item in the MR to report the MR, so that the base station receives a plurality of MRs reported by different terminals and/or the same terminal in a period of time, for example, in one day, and selects the MR reported by the terminal (different terminals or the same terminal) residing in the cell 1 from the plurality of MRs according to the content item of the signal strength of the main service cell, namely the cell 1, in which the terminal currently resides, and reads out each geographical location information where the terminal resides in the target cell, i.e., cell 1, from the picked up MRs. Assuming that the number of geographic locations where the terminal read by the base station from the MR resides in the cell 1 is Q, if each geographic location is represented by a corresponding longitude and latitude, Q longitude and latitude can be obtained, where Q is a positive integer greater than or equal to 1. And then, the base station clusters/aggregates the Q longitude and latitude information to obtain the longitude and latitude P corresponding to the signal coverage central area of the target cell. Specifically, the clustering/aggregating process includes:

calling a geographic grid table, as shown in fig. 4, the geographic grid table can be represented by M rows by N columns of cells, M, N are positive integers greater than or equal to 1, each cell is a grid area, each grid area represents a latitude and longitude within a certain range, and every two adjacent cells in the latitude and longitude can have a certain degree difference. For example, the longitude and latitude represented by the 1 st grid area (row 1, column 1) in the geographic grid table are from (31 ° E, 31 ° N) to (35 ° E, 35 ° N), and the longitude and latitude represented by the 2 nd grid area (row 1, column 2) are from (36 ° E, 36 ° N) to (40 ° E, 40 ° N), i.e., every two adjacent grids differ by 5 ° in longitude and latitude. For the selected Q pieces of longitude and latitude information, starting from the 1 st piece of longitude and latitude information, the base station judges one by one in which grid area each longitude and latitude can fall, that is, mapped, for example, the 1 st longitude and latitude in the Q pieces of longitude and latitude information is (37 ° E, 36 ° N), then the 1 st longitude and latitude can fall, that is, mapped, in the 2 nd grid area, the last 1 longitude and latitude in the Q pieces of longitude and latitude information is (32 ° E, 32 ° N), then the last 1 longitude and latitude can fall, that is, mapped, in the 1 st grid area in the geographic grid table, and so on, all mappings to the Q pieces of longitude and latitude information are completed, that is, the Q pieces of longitude and latitude information find the corresponding grid areas, and correspondingly, at least part of the grid in the geographic grid table is mapped with certain longitude and latitude. The base station screens out grid areas mapped with the longitude and latitude from the M-to-N grids, and screens out grid areas with the longitude and latitude, wherein the number of the longitude and latitude mapped in the grid areas is larger than or equal to a first threshold value, and the grid areas are determined to determine that the screened grid areas are target grid areas, the number of the target grid areas is L, and L is a positive integer larger than or equal to 1; the first threshold is preset and can be flexibly set according to actual use conditions, for example, the value is 50 or 80 or any other reasonable value that can be thought of. In the L target grid areas, reading all longitude and latitude information mapped in each target grid area to obtain R longitude and latitude information, where R is a positive integer greater than or equal to 2 and less than or equal to Q, performing (arithmetic) average operation, or performing weighted average operation, or performing root-mean-square average operation on the R longitude and latitude, to obtain longitude and latitude (first longitude and latitude information) corresponding to the coverage center area of the target cell, and then obtaining the coverage center area of the target cell, i.e., cell 1.

After calculating the coverage center area of the cell 1, the base station calculates an angle to be rotated when the base station is rotated to the reference direction of the coverage center area from the reference direction of the cell 1 by taking the reference direction of the cell 1 as the east-ward direction of the base station and taking the direction of a connecting line between the base station and the coverage center area as the reference direction of the coverage center area as an example, and judges whether the rotated angle is located in a first preset range, whether the rotated angle is located in 1/2 target cell lobe angle or not, and if the rotated angle is located in the first preset range, the base station judges that an antenna feed system of the target cell has no abnormality; if not, judging that the antenna feed system of the target cell is abnormal.

After the base station calculates the coverage center area of the cell 1, taking the position which is 200m away from the base station along the reference direction of the cell 1 as the reference point of the cell 1 as an example, calculating the linear distance between the base station and the coverage center area of the calculated target cell, and judging whether the distance is within the first preset range or not, and if so, determining that the antenna feeder system of the cell 1 has no abnormality; if not, judging that the antenna feed system of the cell 1 has abnormity.

In the above solution, the first preset range, the reference direction of the target cell, the reference point position, and the reference direction of the coverage center area may all be flexibly set according to actual situations, and are not limited to the above.

In fig. 3(a) and (b), the position marked by "sun" is the coverage center area of the cell 1 calculated by the above scheme, and in fig. 3(a), the coverage center area is located in the signal coverage area of the cell 1 and close to the reference direction of the cell 1, in which case the antenna feed system of the cell 1 has no abnormality. The coverage centre area calculated in fig. 3(b) is outside the signal coverage of cell 1, i.e. within the signal coverage of cell 2, in which case the antenna feed system of cell 1 is abnormal.

It should be understood by those skilled in the art that the existence of an abnormality in the antenna feeder system of the cell 1 may include at least the following two cases: one is that the radiation direction of the antenna in the antenna feed system deviates from a desired angle. The other is that the connection error of the antenna feeder system between the cell 1 and its neighboring cell, such as the cell 2, such as the antenna feeder connection, is reverse, and the antenna feeder connection has a characteristic that the coverage areas of the 2 cells are reversed, that is, the coverage center range of the cell 1 calculated by the geographical location information reported when the terminal resides in the cell 1 falls within the signal coverage area of the cell 2.

In the scheme, a base station estimates a coverage center area of a target cell according to a plurality of geographical position information reported when a terminal resides in the target cell, and obtains first data based on information such as a distance between a reference point of the target cell and the coverage center area and/or an angle required to be rotated when the reference direction of the target cell is rotated to the reference direction of the coverage center area, and further determines whether an antenna feed system of the target cell is abnormal or not according to a judgment result of whether the first data is located in a first preset range. Compared with the existing mode of determining whether the antenna feeder system is abnormal or not by adopting a manual checking mode, the automatic detection method realizes the automatic detection of whether the antenna feeder system is abnormal or not, can greatly reduce manpower and material resources, can effectively improve the detection accuracy, and avoids the problem of low accuracy caused by manually checking the abnormality of the antenna feeder system.

In a first embodiment of the antenna feeder system detection apparatus provided by the present invention, the apparatus is located in a base station, the base station includes at least one cell, preferably three cells, and each cell obtains a certain signal coverage area through configuration of a corresponding antenna feeder system.

Fig. 5 is a schematic structural diagram of a first embodiment of a detection device of an antenna feed system according to the present invention; as shown in fig. 5, the apparatus includes: a first acquisition unit 51, a first determination unit 52, a second acquisition unit 53, a first judgment unit 54, and a second determination unit 55; wherein,

a first obtaining unit 51, configured to obtain at least one piece of first information of at least one terminal, where the first information is used to represent geographical location information of the terminal, and the terminal is a terminal that resides in a target cell;

the terminal selects one of the at least one cell as a primary serving cell, for example, selects cell 1 as the primary serving cell from cell 1, cell 2 and cell 3. Along with the movement of the terminal, the terminal may move from one cell to another cell, and also move from one location to another location in the same cell, the terminal may report the current geographical location information to the base station periodically, for example, once every 5min or 150s, and the apparatus, specifically, the first obtaining unit 51 receives the information reported by the terminal. The terminal can collect the geographic position information through a built-in Global Positioning System (GPS) module, an auxiliary global positioning system (A-GPS) module and/or a Geographic Information System (GIS) module and report the geographic position information after the collection is finished. Because the a-GPS module is more accurate in positioning, the terminal preferably performs positioning of the geographical location through the a-GPS module, so that the subsequent base station can more accurately position the coverage center area of the target cell based on the geographical location.

In practical applications, since the terminal reports a Measurement Report (MR) to the base station periodically, the measurement report may include at least the following: the signal strength of a cell (main serving cell) where the terminal currently resides, the current transmit power of the terminal, and the signal strength of at least one neighboring cell (neighbor cell) of the main serving cell. According to the scheme, a content item is added in the MR, the geographic position information of the terminal is used as the content of the content item, and the content is reported regularly along with other content in the MR.

Since the number of cells under the base station is usually greater than or equal to 1, the location of the terminal is usually changed many times, and the apparatus, specifically, the MR received by the first obtaining unit 51 is an MR where the terminal resides under each cell of the base station, if the target cell is selected, the first obtaining unit 51 should select, from the multiple MRs, an MR reported by the terminal while residing under the target cell, and read, from the selected MR, each geographical location information where the terminal resides when it resides in the target cell. It is worth noting that: as the terminal moves, the main serving cell of the terminal may change, and the target cell may specifically be the main serving cell of the terminal, or may also be a cell adjacent to the main serving cell, that is, a neighboring cell.

the apparatus, specifically the second obtaining unit 53 obtains a distance between the reference point of the target cell and the coverage center area and/or an angle that needs to be rotated when turning from the reference direction of the target cell to the reference direction of the coverage center area.

For example, the reference direction of the target cell is configured to be the southeast direction, the northwest direction, or the true east/south/west/north direction of the cell, or may be the southeast direction, the northwest direction, or the true east/south/west/north direction of the base station to which the cell belongs; the position of 300m, for example, along the base station direction of the target cell and within a certain range from the base station may be the reference point of the target cell, or the center position of the target cell may be the base station. In the scheme, the reference point and the reference position have a reference function, the reference point and the reference position are not specifically limited, and the position and the direction which can have the reference function can be both used as the reference point and the reference direction.

The terminal can collect the geographic position information through a built-in Global Positioning System (GPS) module, an auxiliary global positioning system (A-GPS) module and/or a Geographic Information System (GIS) module and report the geographic position information after the collection is finished. Because the a-GPS module is more accurate in positioning, the terminal preferably performs positioning of the geographical location through the a-GPS module, so that the subsequent base station can more accurately position the coverage center area of the target cell based on the geographical location.
