Fig. 1 is a schematic diagram of a network system provided in an embodiment of the present application.
As shown in fig. 1, the network system includes: the system comprises an operation maintenance subsystem, a control subsystem and an antenna subsystem, wherein the antenna subsystem comprises a plurality of antennas, and each antenna is provided with an image acquisition device such as a camera. Fig. 1 also shows the antenna and its surroundings in buildings such as office buildings, cells, residential and commercial centers, etc.
The antenna subsystem is used for acquiring a live-action image corresponding to the surrounding environment of the antenna. Optionally, the antenna subsystem includes an antenna controller, and the antenna controller is configured to control a camera on the antenna to acquire a real-scene image corresponding to the environment around the antenna. Optionally, the antenna subsystem is configured to use a camera on the antenna to capture a corresponding live-action image in an environment surrounding the antenna under direct control of the control subsystem. It should be noted that the real-scene image described in this application may be a panoramic image within 360 ° of the antenna, or may be an image in the surrounding environment of the antenna corresponding to the radiation direction of the antenna, and this application is not limited in any way.
The control subsystem is used for acquiring a live-action image. Optionally, the control subsystem receives the live-action image sent by the antenna subsystem. Optionally, the control subsystem is configured to receive indication information indicating to obtain the live-action image, and control a camera on the antenna to perform image acquisition according to the indication information and generate the live-action image.
The control subsystem is further used for determining a first three-dimensional signal coverage range of the antenna according to the physical parameter information of the antenna, and mapping the first three-dimensional signal coverage range of the antenna to the live-action image to obtain a signal coverage effect image of the antenna in the surrounding environment of the antenna. It can be understood that the control subsystem has a real-scene fitting function, and is configured to perform image processing based on a real-scene image in which a signal coverage range of the antenna corresponds to an environment around the antenna to obtain a signal coverage effect of the antenna in the real-scene image.
The control subsystem may also be used to automatically analyze and process live-action images to identify obstacles, buildings, traffic, people, unmanned aerial vehicles, and the like.
The operation maintenance subsystem is used for network maintenance, has an integration function of signal coverage areas of different antennas or cells, and achieves the effect of displaying the overall network signal coverage of one or more cells in an imaging mode.
As can be seen from fig. 1, there may be large buildings in the environment around the antenna, and these buildings may affect the signal coverage of the antenna, especially in a network system that uses electromagnetic waves with weak penetration ability, such as millimeter waves, for data transmission, including but not limited to a 5G mobile communication system, which is easy to cause signal blocking and affect the signal coverage.
By the method for acquiring the signal coverage effect, the sheltering object sheltered by the signal can be quickly positioned, and the coverage range of the network signal is adaptively adjusted, so that the problem of signal sheltering is effectively solved.
It should be noted that the network system shown in fig. 1 is only one network system used in the method of the present application, and the method of the embodiment of the present application is applicable to, but not limited to, the network system shown in fig. 1.
In order to facilitate understanding of the method for acquiring the signal coverage effect diagram provided in the embodiment of the present application, the following describes in detail the technical solution in the present application with reference to a specific embodiment.
Fig. 2 is a schematic diagram of an embodiment of a method for acquiring a signal coverage effect graph according to an embodiment of the present application.
201. The network equipment acquires a live-action image which is an image of the surrounding environment of the antenna.
As described above, the method for acquiring the live-action image by the network device is similar to the method for acquiring the control subsystem, and is not described herein again. As shown in fig. 3, a live-action image corresponding to the antenna is acquired by the camera.
202. And the network equipment determines the second three-dimensional signal coverage range of the antenna according to the height, the azimuth angle and the inclination angle of the antenna.
The azimuth angle of the antenna is substantially the azimuth of the antenna when mounted, and similarly, the inclination angle of the antenna is the orientation of the antenna when mounted, and it is conceivable that a three-dimensional antenna signal coverage area similar to a cone can be roughly determined according to the orientation and azimuth of the antenna, and the position of the cone center of the cone is determined according to the height of the antenna, so that a three-dimensional area can be roughly determined by the above-mentioned physical information, and it can be understood that an area that cannot be within the antenna coverage area can be roughly excluded according to the orientation and azimuth of the antenna. It should be noted that, the second three-dimensional range is determined according to the following factors including, but not limited to, the height, azimuth angle and inclination angle of the antenna, and may also include other installation information of the antenna, which is not limited in this application.
203. And the network equipment calculates to obtain a third three-dimensional signal coverage range of the antenna by utilizing the electromagnetic wave principle according to the antenna power parameter.
Optionally, based on the electromagnetic wave principle, parameters such as the wavelength, the frequency, and the transmission function of the antenna are calculated to obtain the coverage area of the second three-dimensional signal, and it is easy to think that the theoretical signal coverage area of the antenna, that is, the coverage area of the third three-dimensional signal, can be roughly estimated theoretically through the above antenna parameters. It should be noted that, in the theoretical calculation process of the signal coverage area of the antenna, the antenna parameters are not limited to the power parameter, the frequency parameter, and the wavelength parameter, and may also include other parameter information required by the theoretical calculation, which is not limited in this application.
204. The network device determines an overlapping portion of the second three-dimensional signal coverage and the third three-dimensional signal coverage as the first three-dimensional signal coverage of the antenna.
The overlapping part of the second three-dimensional signal coverage range and the third three-dimensional signal coverage range is used for determining the first three-dimensional signal coverage range, and various physical parameter information (including antenna height, azimuth angle, inclination angle, antenna power parameter, antenna wavelength parameter and antenna frequency parameter) of the antenna can be comprehensively considered, so that the first three-dimensional signal coverage range is more accurate.
It is understood that the above steps 202 to 203 are a specific implementation manner of determining the first three-dimensional signal coverage of the antenna according to the physical parameter information of the antenna described in the above fig. 1, where the physical parameter information of the antenna includes, but is not limited to, an antenna height, an azimuth angle, an inclination angle, an antenna power parameter, an antenna wavelength parameter, and an antenna frequency parameter, and the physical parameter information of the antenna may further include other parameter information related to the signal coverage of the antenna, which is not limited in this application.
205. And the network equipment maps the first three-dimensional signal coverage range to the live-action image to obtain a signal coverage effect diagram of the antenna in the surrounding environment of the antenna.
Optionally, the obtaining manner of the signal coverage effect map may specifically be: according to the position of the antenna, the first three-dimensional signal coverage range of the antenna and the live-action image corresponding to the surrounding environment of the antenna are subjected to fitting operation to obtain a signal coverage effect image, in other words, the first three-dimensional signal coverage range of the antenna is fitted to the live-action image to obtain the actual coverage effect of the antenna in the live-action. It should be noted that the fitting operation may use a corresponding three-dimensional rendering component to implement the fitting function, which is not described herein again. Optionally, the antenna position includes a longitude and a latitude. In the process of the fitting operation, the method may further include:
optionally, if a signal coverage area with a Key Performance Indicator (KPI) lower than a preset threshold exists in the signal coverage effect of the antenna, the network device marks the signal coverage area with the KPI lower than the preset threshold in a signal coverage effect map of the antenna.
Optionally, if there is a specific abnormal signal coverage area in the signal coverage effect of the antenna, the network device marks the specific abnormal signal coverage area in the signal coverage effect map of the antenna.
The marking method may specifically be rendering by using a specific color, so that a signal coverage area where the KPI is lower than a preset threshold or where a specific abnormality exists is visually displayed on a signal coverage effect diagram. The specific anomalies include, but are not limited to, signal coverage blocked by obstacles such as buildings and overlapping signal coverage between different antennas.
It should be noted that, in a real-scene image, the signal coverage ranges of multiple antennas may be within, and in this case, the network device may fit the signal coverage ranges corresponding to the multiple antennas in a real-scene image to obtain the signal coverage effect of the signal coverage ranges of the multiple antennas in the real-scene image. The signal coverage of three antennas is fitted in a live view image as shown in fig. 4, wherein the ellipse-shaped mark portion in fig. 4 is substantially a three-dimensional solid space rather than a two-dimensional plane, and is simply marked as an ellipse as shown in fig. 4 for convenience of illustration. It is obvious from fig. 4 that there is a specific abnormal phenomenon that the building blocks the signal, that is, there is a large building in the radiation direction of one antenna in fig. 4 to block the signal, and the signal coverage of the blocked part can be specifically marked, which is not shown in fig. 4. It is also apparent from fig. 4 that there is a specific anomaly that signal coverage areas of different antennas overlap each other, and the signal coverage areas that overlap each other may also be labeled specifically, which is not shown in fig. 4.
It should be further noted that, by using the above technical solution, the signal coverage of a cell or a base station can be further obtained, which is not limited in this application. It is easily understood that multiple antennas are typically deployed in a cell, and that one base station covers multiple cells simultaneously.
In the embodiment of the application, the actual signal coverage effect diagram of the antenna in the live-action image is presented in an imaging mode, so that the signal coverage range is visualized, the sheltering object of the antenna in the actual signal coverage range can be quickly positioned, the sheltered signal coverage range is further properly adjusted, the signal coverage effect of the antenna is enhanced, in addition, the unreasonable coverage condition covered by two or more antennas can be determined according to the signal coverage effect diagram, the parameters, the positions and the like of the antenna are timely adjusted, and the signal coverage range of the antenna is reasonably distributed.
Furthermore, the network equipment can also dynamically adjust the antenna array based on the image change of the signal coverage effect diagram and the antenna parameter change, so that the network coverage effect is improved, and the network optimized real-scene effect can be seen in real time.
The following describes in detail a method for acquiring a signal effect diagram in the embodiment of the present application with reference to a specific application scenario.
Fig. 5 is a schematic diagram of a graphical network maintenance provided in an embodiment of the present application.
As shown in fig. 5, includes:
501. the operation and maintenance center receives user indication.
The user instruction received by the user at the Operation Maintenance Center (OMC) refers to a signal coverage effect diagram sent by the user for viewing a part or all of the signal coverage areas of the base station. For example, in a live-action mode, a user selects a target base station on an OMC client or an OMC browser to view a signal coverage effect diagram corresponding to the target base station, it is easy to understand that the OMC may be set to view the signal coverage effect diagram in a specified mode, for example, the user may view the signal coverage effect diagram in the live-action mode, and if the user cannot view the signal coverage effect diagram in the specified mode, but may view a signal coverage deployment diagram, for example, in a video mode, the user may view the signal coverage deployment diagram of the target base station, it is easy to understand that the signal coverage deployment diagram may be understood as a theoretical signal coverage which does not include a live-action corresponding to a coverage. It is to be understood that the user instruction in the present embodiment specifically refers to an instruction in the live view mode.
502. And the operation maintenance center acquires the cell configuration information.
The cell configuration information includes: the number of antennas in a cell, the correspondence between cells and antennas, and physical parameter information of all antennas in a cell.
In a specific embodiment, after the OMC client or the OMC browser obtains the target base station according to the instruction of the user, the OMC client or the OMC browser may prompt the user to select a cell corresponding to the target base station for browsing, and if the user does not select the cell, the signal coverage effect maps of all cells in the target base station are checked by default.
503. And the operation maintenance center sends the cell configuration information to the graphic association controller.
504. The graphics association controller sends a live-action image acquisition request to the antenna controller.
505. The antenna controller controls the image acquisition equipment on the antenna to acquire the live-action image.
506. And the antenna controller sends the live-action images corresponding to all the antennas in the cell to the graphic association controller.
507. And the pattern association controller fits the signal coverage range of the antenna to the live-action image according to the physical parameter information of the antenna to obtain a signal coverage effect pattern of the antenna.
508. And the pattern association controller sends the signal coverage effect patterns of all the antennas in the cell to an operation and maintenance center.
509. And the operation maintenance center performs correlation integration on the signal coverage effect maps of all the antennas in the cell to obtain the signal coverage effect map of the cell.
