[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0026] To facilitate a better understanding of the embodiments of this application by those skilled in the art, some technical terms or nouns involved in the embodiments of this application are explained as follows:

[0027] LTE (Long Term Evolution): is a transition between 3G and 4G technologies, and is a global standard for 3.9G. It is usually an abbreviation for 4G technology.

[0028] 5G NR (New Radio): is a new wireless access technology used in 5G (5th Generation Mobile Communication Technology) mobile communication networks, and is usually an abbreviation for 5G technology.

[0029] Band: In communications, it mainly refers to the frequency range of electromagnetic waves that carry information transmission. Band 1 usually refers to the L2100MHz frequency range, band 3 usually refers to the L1800MHz frequency range, and band 5 usually refers to the L800MHz frequency range.

[0030] N1 typically refers to the 5G NR 2100MHz frequency range, N5 typically refers to the 5G NR 800MHz frequency range, and N78 typically refers to the 5G NR 3300MHz-3600MHz frequency range.

[0031] The three traditional wireless network optimization techniques all suffer from the limitation of only being able to adjust first and then evaluate:

[0032] The first approach involves optimizing the radio frequency of existing base stations. Based on optimization experience, this involves manually climbing to the top of the tower to adjust the azimuth and downtilt angles of the base station antennas. This may result in multiple attempts to adjust the antennas without achieving the desired effect.

[0033] Secondly, it is impossible to determine whether adding sectors to existing base stations can effectively solve the problem of weak coverage areas.

[0034] Third, regarding newly built base stations, it is impossible to determine whether building a new base station at the current location can effectively solve the problem of weak coverage areas.

[0035] To address the aforementioned issues, this application provides a solution: a UAV-based base station signal coverage simulation device. This device has significant theoretical and engineering value for evaluating wireless network coverage capabilities and improving the effectiveness of base station RF optimization and new construction. The details are described below.

[0036] According to an embodiment of this application, an embodiment of a base station signal coverage simulation device is also provided, the structure of which is as follows: Figure 1 , Figure 2 As shown, the device includes: a drone body 1, a support frame 2, a fixing component 7, and a signal transmission simulator 4.

[0037] The drone body 1 is used to respond to the first control command and fly to the flight altitude indicated by the first control command, wherein the flight altitude is equivalent to the mounting height of the base station antenna;

[0038] The support frame 2 is fixed to the surface of the UAV body 1, and a fixing component 7 is provided on the side of the support frame 2. The fixing component 7 is used to fix the signal transmission simulator 4, and in response to the second control command, it is adjusted to the fixed angle indicated by the second control command to control the signal transmission direction of the signal transmission simulator 4.

[0039] The signal transmission simulator 4 is connected to the fixed component 7 and is used to send a signal conforming to the signal parameters indicated by the third control command to the test area in response to the third control command, so as to simulate the base station signal transmission.

[0040] In some embodiments of this application, the signal parameters that the signal transmission simulator 4 supports configuration include at least one of the following: signal frequency range, reference signal transmission power, subcarrier bandwidth, and number of resource blocks.

[0041] Specifically, the signal transmission simulator 4 can support full-band simulation, including LTE band1, band3, and band5, as well as 5G NR N1, N5, and N78; it can also remotely configure information such as reference signal transmission power, subcarrier bandwidth, and number of RBs (Resource Blocks) through the control terminal, thereby simulating base station signal transmission.

[0042] In this embodiment, the control module can remotely and dynamically send parameters such as azimuth angle, downtilt angle, and reference signal transmission power to the aforementioned base station signal coverage simulation device to simulate the process of manual on-site adjustment. Then, in conjunction with a ground test terminal, the signal strength under different parameter configurations is tested in the target coverage area (i.e., the test area) to determine whether adjusting existing network sectors, adding new sectors, or building new base stations can effectively solve the weak coverage problem. Finally, the optimal parameter configuration is verified for manual tower adjustment, thereby improving the accuracy of base station optimization and construction, avoiding repeated on-site adjustments and ineffective base station construction, achieving cost reduction and efficiency improvement, and thus solving the technical problem of repeated on-site adjustments and ineffective base station construction caused by the fact that related technologies can only optimize the wireless network of base stations by adjusting first and then evaluating.

[0043] The base station signal coverage simulation device according to the embodiments of this application will be further described below.

[0044] In this embodiment, the base station signal coverage simulation device may further include: a photographing device 3 and a cleaning component 5, as detailed below.

[0045] In some embodiments of this application, the support frame 2 includes: a first support frame and a second support frame, which are respectively fixed to both sides of the lower surface of the UAV body; the base station signal coverage simulation device also includes: a camera 3 and a cleaning component 5, wherein the camera 3 is fixed to the lower surface of the UAV body 1 and is used to collect images in the signal transmission direction during the flight of the UAV body 1; the cleaning component 5 is disposed on the side of the support frame 2 and can reciprocate between the first support frame and the second support frame, and is used to clean the camera surface of the camera 3.

[0046] The following section will provide a further introduction to the specific structure and working principle of cleaning component 5.

[0047] In some embodiments of this application, the cleaning component 5 includes: a first driving device 501, a rotating shaft 502, a threaded tube 503, a cleaning block 506, a telescopic connecting rod 508, and a push plate. The first driving device 501 is fixed on a first support frame and is used to drive the rotating shaft 502 to rotate. The rotating shaft 502 is connected to the output shaft of the first driving device 501. The surface of the rotating shaft 502 is provided with threads and is movably connected to the threaded tube 503 through the threads. The end of the threaded tube 503 is fixed with a push plate. The threaded tube 503 is used to drive the push plate to reciprocate between the first support frame and the second support frame as the rotating shaft 502 rotates, so as to drive the cleaning block 506 to move.

[0048] In addition, a connecting rod 508 is fixed to the side of the support frame 2. One end of the connecting rod 508 is fixed to the first support frame, and the other end is fixed to the push plate.

[0049] The lower surface of the drone body 1 is provided with a movable groove, a slide rod is fixed in the inner wall of the movable groove, a slide sleeve is sleeved on the slide rod, and a cleaning block 506 is fixed on the surface of the slide sleeve. The side of the cleaning block 506 can fit against the surface of the camera of the photography device 3.

[0050] In some embodiments of this application, an electromagnet 6 is also fixed on the second support frame (or the lower surface of the UAV body 1). The electromagnet 6 can attract the cleaning block 506. A first spring is also sleeved on the surface of the slide rod. One end of the first spring is fixed to the inner wall of one end of the movable groove, and the other end is fixed to the side of the slide sleeve. When the electromagnet 6 is energized, the cleaning block 506 is attracted to one end of the second support frame. When the electromagnet 6 is de-energized, the slide sleeve, under the action of the first spring, drives the cleaning block 506 to move towards the push plate.

[0051] The working principle of Cleanup Component 5 will be explained in detail below.

[0052] When staff need to clean the surface of the camera device 3, they only need to control the electromagnet 6 to stop operating via an external control terminal (e.g., a control terminal), thereby disengaging the cleaning block 506 from the electromagnet 6. With the cooperation of the first spring, the sliding sleeve and the cleaning block 506 fixed on the surface of the sliding sleeve can be moved towards the push plate. Subsequently, the first drive device 501 operates, driving the rotating shaft 502 to rotate. The rotating shaft 502 drives the threaded tube 503 to move, thereby driving the push plate fixed at one end of the threaded tube 503 to move synchronously, pushing the cleaning block 506 to reciprocate, thus cleaning the surface of the camera device 3. After cleaning is completed, the electromagnet 6 is controlled to operate again, and the cleaning block 506 is attracted to the side of the electromagnet 6.

[0053] In this embodiment, the cleaning component 5 can clean the surface of the camera of the camera device 3, preventing dust or debris from adhering to the surface of the camera device 3 during the flight of the drone body 1. This would cause the camera device 3 to make incorrect judgments about whether there are obstructions in the coverage direction of the base station antenna, resulting in errors in the signal simulation effect. It would also have a certain impact on the camera device 3 when checking whether the antenna port feeder connection is loose or damaged.

[0054] The specific structure of the aforementioned fixed components will be further described below.

[0055] In some embodiments of this application, the fixing components include: a second driving device 701, a first fixing frame 703, a second fixing frame 705, a rotating shaft 704, a second spring 702, a telescopic rod 706, and a fixing plate. The first fixing frame 703 and the second fixing frame 705 are respectively fixed to the first support frame and the second support frame via the rotating shaft 704. The rotating shaft 704 can be fixed to the side of the support frame 2 via a bearing.

[0056] The second drive device 701 is connected to the rotating shaft 704 and is used to adjust the angle of the rotating shaft 704 in response to the second control command. The sides of the first fixed frame 703 and the second fixed frame 705 are fixed with a telescopic rod 706. The surface of the telescopic rod 706 is sleeved with a second spring 702. The end of the telescopic rod 706 is connected to a fixed plate. The fixed plate can fit against the signal transmission simulator 4. The telescopic rod 706 is used to drive the fixed plate to fit against the signal transmission simulator 4 under the action of the second spring 702, so as to clamp the signal transmission simulator 4 through the fixed plate on the first fixed frame 703 and the fixed plate on the second fixed frame 705.

[0057] It should be noted that in this embodiment, multiple telescopic rods 706, second springs 702, and fixing plates can be provided and symmetrically arranged on the sides of the first fixing frame 703 and the second fixing frame 705. In this embodiment, the fixing component 7 can fix the signal transmission simulator 4, preventing it from shifting or shaking during the flight of the UAV body 1, which could cause it to fall off the surface of the UAV body 1 and damage the equipment. Simultaneously, it ensures that the signal transmission simulator 4 remains stable when adjusting the pitch or tilt angle, thereby enabling it to accurately transmit simulated signals according to the specified azimuth and tilt angles, improving measurement accuracy.

[0058] In addition, in the base station signal coverage simulation device, a sensing module 8 is also fixed on the surface of the signal transmission simulator 4. The sensing module 8 is connected to the signal transmission simulator 4 and is used to determine the pose information corresponding to the signal transmission simulator 4 when it transmits a signal. The pose information includes at least one of the following: altitude, azimuth angle, and pitch angle, and is transmitted to the control end.

[0059] The following describes the process of using the aforementioned base station signal coverage simulation device to simulate and test base station signal coverage.

[0060] First, the signal transmission simulator 4 is fixed to the bottom of the drone body 1 by the fixing component 7. The first control command is sent through the external control terminal to control the drone body 1 to fly to a height equivalent to the height of the base station antenna. The camera device 3 is used to check whether there are any obstructions in the surrounding area. Before the camera device 3 checks whether there are any obstructions in the surrounding area, the surface of the camera device 3 can be cleaned by the cleaning component 5.

[0061] Then, staff can send second and third control commands to the base station signal coverage simulation device through the control terminal, and remotely and dynamically send azimuth angle, downtilt angle and other angle parameters, as well as reference signal transmission power and other signal parameters to the second drive device 701 and signal transmission simulator 4 to simulate the process of manual on-site adjustment.

[0062] Afterwards, ground testing terminals can be used to test signal strength under different parameter configurations in the target coverage area (i.e., the test area) to determine whether adjusting existing network sectors, adding new sectors, or building new base stations can effectively solve the weak coverage problem, thereby determining the final target parameter configuration. Finally, the optimal target parameter configuration is verified by manual tower adjustment to improve the accuracy of base station optimization and construction.

[0063] According to an embodiment of this application, a method embodiment for simulating base station signal coverage is also provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
