[0042] The terms used in the following embodiments are only for the purpose of describing specific embodiments, and are not intended to be used as limitations on the present application. As used in the specification and the appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the following embodiments of the present application, "at least one", "one or more" refer to one, two or more. The term "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0043] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0044] To facilitate understanding, some concepts related to the embodiments of the present application are introduced below.

[0045] Antenna height: generally refers to the vertical distance of the antenna from the ground. Generally, the height of the antenna will affect its performance. For example, in radio communications, the height of the antenna can affect the quality of signal transmission and reception. The higher the antenna is from the ground, the wider its coverage area, but it will also be affected by strong winds and require a more secure installation.

[0046] Azimuth: The azimuth of an antenna refers to the angle between the direction the antenna is pointing and the north direction. For example, when the antenna is pointing to the north, its azimuth is 0 degrees; when the antenna is pointing to the east, its azimuth is 90 degrees.

[0047] Downtilt: The downtilt angle of an antenna is the angle at which the antenna is pointed toward the ground. This angle is usually set to best align the antenna with the desired coverage area. For example, in satellite communications, the downtilt angle is usually set to best position the antenna to receive satellite signals.

[0048] Roll angle: The roll angle of an antenna refers to the rotation angle of the antenna in the horizontal plane. This angle is usually used to adjust the direction of the antenna to better align it with the target.

[0049] The parameters of the antenna, such as the height, azimuth, downtilt, and roll angle, determine the quality and coverage of the antenna signal. In order to improve the quality of wireless signals and expand the coverage of wireless signals, the antenna is usually hung at a higher height. If the parameters of the antenna are obtained and maintained manually, there will be problems such as large workload, low efficiency, large human errors, long acquisition cycle, and inability to achieve real-time monitoring of the antenna status. In addition, after the current antennas are deployed, it is difficult to identify which antenna belongs to which operator, and it is also difficult to determine whether the working environment of the antenna is safe enough.

[0050] An embodiment of the present application provides a base station antenna system, which can obtain parameters such as the hanging height of the antenna in real time with high accuracy.

[0051] Figure 1 Schematic diagram of the structure of a base station antenna system provided in an embodiment of the present application. Figure 1 As shown, the base station antenna system 100 includes an antenna module 110 , a remote radio unit (RRU) 120 , a sensing module 130 and a monitoring terminal 140 .

[0052] The antenna module 110 may be, for example, a multi-frequency antenna system. The antenna module 110 may include multiple antennas, each of which may receive or send signals in different frequency bands. It may simultaneously support multiple radio signals, such as LTE, WiFi, etc.

[0053] The RRU 120 is a radio device that converts digital signals into radio frequency signals and sends them to the antenna for communication with the user equipment. The RRU 120 is usually installed near the antenna and connected to the antenna module 110 via a radio frequency coaxial line to reduce signal transmission loss and delay.

[0054] In some embodiments, the base station antenna system 100 may also include an indoor baseband processing unit (building baseband unit, BBU), which is usually installed in a machine room and is mainly used to complete channel encoding and decoding, baseband signal modulation and demodulation, protocol processing, etc. The BBU is usually connected to the RRU 120 through an optical fiber for transmitting baseband digital signals.

[0055] The sensing module 130 includes a first air pressure measurement module for measuring the atmospheric pressure at the location of the sensing module 130. By installing the sensing module 130 near the antenna module 110, the sensing module 130 can measure the first air pressure at the location of the antenna module 110. The monitoring terminal 140 includes a second air pressure measurement module for measuring the atmospheric pressure at the location of the monitoring terminal 140. By installing the monitoring terminal 140 near the ground, the sensing module 130 measures the second air pressure near the ground.

[0056] The first air pressure and the second air pressure are used to calculate the hanging height of the antenna module 110, that is, the absolute height difference between the antenna system and the ground. Specifically, the height difference between the antenna module 110 and the monitoring terminal 140, that is, the hanging height of the antenna module 110, can be estimated by the air pressure difference between the first air pressure and the second air pressure. For example, the hanging height of the antenna module 110 can be calculated according to the following empirical formula:

[0057] H=(RT / gM)×ln(P1 / P2)

[0058] Among them, H is the hanging height, R is the gas constant, T is the temperature, g is the acceleration due to gravity, M is the molar mass of air molecules, P1 is the first air pressure, and P2 is the second air pressure.

[0059] In some embodiments, the base station antenna system may further include a hanging height calculation module, which is used to calculate the hanging height of the antenna module 110 according to the first air pressure and the second air pressure. For example, the hanging height calculation module may communicate with the sensing module 130 and the monitoring terminal 140 to obtain the first air pressure and the second air pressure, and then calculate the hanging height of the antenna module 110 according to the air pressure difference between the first air pressure and the second air pressure.

[0060] It should be noted that to ensure the accuracy of the hanging height calculation, the distance between the monitoring terminal 140 and the antenna module 110 in the horizontal plane can be less than or equal to the first preset value, that is, the distance between the orthographic projection of the antenna module 110 on the ground and the monitoring terminal 140 is less than or equal to the first preset value.

[0061] It should be noted that installing the monitoring terminal 140 near the ground can be understood as the height between the monitoring terminal 140 and the ground is less than or equal to the second preset value.

[0062] It should be noted that the sensing module 130 is installed near the antenna module 110, which can be understood as the distance between the sensing module 130 and the antenna module 110 is less than or equal to a preset threshold.

[0063] It should be understood that the first preset value and the second preset value are default values ​​or values ​​determined based on experience. For example, the first preset value and the second preset value are 5 meters and 2 meters respectively. Measuring the antenna height within this range is more accurate, and the embodiment of the present application is not limited to this.

[0064] In the embodiment of the present application, in order to determine whether the hanging height data obtained in real time is accurate, before obtaining the hanging height data, it can be determined whether the distance between the monitoring terminal 140 and the antenna module 110 on the horizontal plane is less than or equal to the first preset value. For example, the sensing module 130 can obtain the position information of the antenna module 110 in real time, and the monitoring terminal 140 can obtain its own position information in real time. Combine the position information of the two to determine whether the distance between the monitoring terminal 140 and the antenna module 110 on the horizontal plane is less than or equal to the first preset value. If the distance between the two on the horizontal plane is less than or equal to the first preset value, the first air pressure and the second air pressure can be used to calculate the hanging height.

[0065] In one possible case, when deploying a base station antenna system, the hanging height of the antenna does not refer to the height from the antenna to the ground. For example, after consultation with the operator, it is determined that the hanging height of a certain antenna refers to the height from the antenna to a certain horizontal plane. To measure the hanging height, a sensing module can be set near the antenna, and a monitoring terminal can be set at the height of the horizontal plane. In other words, the embodiment of the present application can flexibly deploy the monitoring terminal to measure the actual hanging height of the antenna.

[0066] It should be understood that the monitoring terminal 140 can be a mobile terminal or a handheld terminal, and the embodiment of the present application does not limit the type of the monitoring terminal 140. For example, the monitoring terminal 140 can be a portable electronic device that also includes other functions such as a personal digital assistant and / or a music player, such as a mobile phone, a tablet computer, a wearable electronic device with wireless communication function (such as a smart watch), etc. Exemplary embodiments of portable electronic devices include but are not limited to devices equipped with Or a portable electronic device with other operating systems. The portable electronic device may also be other portable electronic devices, such as a laptop computer, etc. It should also be understood that in some other embodiments, the electronic device may not be a portable electronic device, but a desktop computer.

[0067] It should be understood that the monitoring terminal may be part of the base station antenna system. For example, the monitoring terminal may be located in a machine room near the base station antenna system, or may be located in a portion of the antenna tower where the antenna module 110 is located close to the ground. Alternatively, the monitoring terminal may not be part of the base station antenna system, and the base station antenna system may obtain the second air pressure at the location of the monitoring terminal. For example, by sending a request message to the monitoring terminal, the measurement data of the second air pressure is requested.

[0068] It should be understood that the air pressure sensor or air pressure measurement module in the embodiments of the present application can be, for example, a barometer, a differential pressure gauge, or other device that can measure atmospheric pressure, and the embodiments of the present application do not limit the type of the air pressure sensor.

[0069] In one possible case, the hanging height of the antenna module 110 may also refer to the altitude of the location where the antenna module 110 is located. However, the measurement error of the altitude is large, and the altitude obtained each time may be different. In this case, even if the altitude is measured multiple times and the average is taken, the accuracy and consistency of the hanging height cannot be guaranteed. Therefore, the altitude directly measured cannot be used as the hanging height of the antenna module 110. In the case where the hanging height of the antenna module 110 refers to the altitude of the location where the antenna module 110 is located, the embodiment of the present application provides a base station antenna system, which can more accurately and conveniently obtain the hanging height of the antenna of the base station antenna system, which is conducive to the maintenance and management of the base station antenna system.

[0070] In some embodiments, the sensing module 130 may also be provided with a global navigation satellite system (GNSS), such as a global positioning system (GPS) and other positioning systems, which may be used to measure the three-dimensional coordinates of the location of the antenna module 110, thereby obtaining the altitude of the location of the antenna module 110. Exemplarily, the global satellite navigation system may be, for example, a GPS signal receiver. The distance between the receiver and the satellite is calculated using the satellite signal received by the GPS signal receiver, and then the position of the satellite in space is determined based on the orbital parameters and clock error of the satellite, and then the receiver's clock error and atmospheric delay are corrected to solve the coordinates of the receiver in the spatial rectangular coordinate system, and finally converted into the longitude and latitude and altitude in the geographic coordinate system, i.e., the three-dimensional coordinates of the antenna module 110.

[0071] As is well known, there is a corresponding relationship between air pressure and altitude, that is, the higher the altitude, the lower the air pressure. Therefore, the embodiment of the present application can also use the air pressure at the location of the antenna module 110 to estimate the altitude of the antenna module 110. As described above, the sensing module 130 includes a first air pressure measurement module for measuring the atmospheric pressure at the location of the sensing module 130. By installing the sensing module 130 near the antenna module 110, the sensing module 130 can measure the first air pressure at the location of the antenna module 110. The altitude of the location of the antenna module 110 can also be obtained through the first air pressure.

[0072] It should be noted that the change in the air pressure data measured at the same location is usually small, that is, the error range of the altitude data obtained by air pressure conversion is usually small. However, the altitude obtained by air pressure conversion is easily affected by factors such as temperature, humidity, and weather, and cannot be used as the hanging height of the antenna module 110.

[0073] In an embodiment of the present application, the altitude data of the location of the antenna module 110 obtained by the global satellite navigation system is recorded as the first altitude data, and the altitude data of the location of the antenna module 110 obtained by the first air pressure conversion is recorded as the second altitude data. Among them, the error range of the first altitude data is larger, while the error range of the second altitude data is smaller. In an embodiment of the present application, the first altitude data can be corrected by the second altitude data, so as to obtain a more accurate and consistent hanging height of the antenna module 110. In other words, the embodiment of the present application can use the first air pressure to correct the altitude obtained by the global satellite navigation system, so as to obtain a more accurate and consistent hanging height of the antenna module 110.

[0074] For example, the lowest altitude of the first altitude data is 975 meters and the highest altitude is 1025 meters, while the lowest altitude of the second altitude data is 990 meters and the highest altitude is 1000 meters. Data less than 990 meters and greater than 1000 meters are removed from the first altitude data, and the average of the remaining data is taken as the hanging height of the antenna module 110.

[0075] In some embodiments, the sensing module 130 may also be provided with a temperature sensor for obtaining the ambient temperature near the sensing module 130. Since the air pressure is greatly affected by the temperature, the present application may also use the ambient temperature to correct the first air pressure, and then use the corrected first air pressure to correct the altitude measured by the global satellite navigation system, thereby obtaining a more accurate and consistent hanging height of the antenna module 110.

[0076] It should be understood that at this time, the base station antenna system may not include the monitoring terminal 140. Figure 2Schematic diagram of an application scenario of a base station antenna system provided in an embodiment of the present application. Figure 2 As shown, the base station antenna system 100 may further include an antenna tower 150, and the antenna module 110 may be installed on the antenna tower 150. Usually, the antenna tower 150 may be fixed on the top of a building to obtain a higher hanging height, thereby improving the quality of wireless signals and expanding the coverage of wireless signals.

[0077] By setting the monitoring terminal 140 near the ground, the second air pressure near the ground can be obtained; combined with the first air pressure obtained by the sensing module 130 set near the antenna module 110, the hanging height of the antenna module 110 can be accurately calculated.

[0078] It should be understood that the hanging height of the antenna module 110 at this time is the vertical distance between the antenna module 110 and the ground (not the top of the building).

[0079] It should be understood that the building is fixed on the ground, and the top of the building has a certain height from the ground.

[0080] It should be understood that the building may be, for example, a man-made building such as a man-made building, and the embodiments of the present application are not limited to this.

[0081] Figure 3 FIG. 1 is a schematic diagram of another application scenario of a base station antenna system provided in an embodiment of the present application. Figure 3 As shown, the antenna module 110 can be installed on the upper part of the antenna tower 160. Figure 2 The difference between the illustrated embodiment and the antenna tower 160 is that the antenna tower 160 itself has a relatively high height, and the antenna tower 160 is not fixed on the top of a building, but is fixed on the ground.

[0082] In this case, the monitoring terminal 140 is arranged near the ground to obtain the second air pressure near the ground, and the first air pressure obtained by the sensing module 130 arranged near the antenna module 110 can be combined to accurately calculate the hanging height of the antenna module 110 .

[0083] Usually, a machine room 170 may be provided near the antenna tower 160. The machine room 170 is used to house equipment such as a base station control unit, a power supply, an air conditioner, and a BBU.

[0084] In some embodiments, the monitoring terminal 140 may be disposed inside the computer room 170 .

[0085] In some embodiments, the monitoring terminal 140 may also be fixed to a portion of the antenna tower 160 close to the ground.

[0086] Figure 4 Schematic diagram of the structure of a perception module provided in an embodiment of the present application. Figure 4As shown, the sensing module may include a first air pressure measurement module, a light emitting module, an orientation detection module, an environment detection module, a first wireless backhaul module, and the like.

[0087] The first air pressure measurement module may include at least one air pressure sensor for measuring air pressure. By arranging the sensing module 130 at the height where the antenna module 110 is located, the sensing module 130 may measure the air pressure at the location where the antenna module 110 is located.

[0088] It should be understood that the air pressure sensor may be, for example, a barometer, a differential pressure gauge, or other device that can measure atmospheric pressure, and the embodiments of the present application are not limited to this.

[0089] The light-emitting module can emit visible light, which is used to identify the operator to which the antenna module 110 belongs. For example, the light-emitting module may include at least one light source, and by setting the number, color, or flashing mode of the at least one light source, the operator to which the antenna module 110 belongs can be distinguished. For example, if the antenna module 110 belongs to operator A, the light-emitting module includes one light source; if the antenna module 110 belongs to operator B, the light-emitting module includes two light sources; or, if the antenna module 110 belongs to operator A, the light-emitting module may include a red light source to emit red light; if the antenna module 110 belongs to operator B, the light-emitting module may include a yellow light source to emit yellow light; or, if the antenna module 110 belongs to operator A, the light-emitting module may flash using a first flashing mode; if the antenna module 110 belongs to operator B, the light-emitting module may flash using a second flashing mode.

[0090] It should be understood that the light source may be, for example, a light emitting diode (LED), a neon lamp, a xenon lamp, a cold light source or other light emitting device, and the embodiment of the present application does not limit the type of the light source.

[0091] In some embodiments, the light emitting module may receive an instruction message from the monitoring terminal 140 , and the instruction message may instruct the light emitting module to emit visible light to identify the operator to which the antenna module 110 belongs.

[0092] The environment detection module may include but is not limited to infrared sensors, temperature sensors, humidity sensors, acceleration sensors, gyroscopes and other devices, and is used to detect the working environment and working status of the antenna module 110.

[0093] Since base stations are usually built outdoors or on the rooftops of tall buildings, they are easily affected by the weather. For example, severe weather conditions such as storms and lightning can damage base station antennas. Wind and gravity can cause antenna displacement. The temperature range in the wild varies greatly, which may cause the antenna to withstand excessive heat or cold, causing equipment components to fail. Animals may also approach base station antennas and damage them.

[0094] By building an infrared sensor into the sensing module, it can identify whether a creature is approaching the antenna. If a creature is approaching the antenna, an early warning message can be sent back to inform the user that a creature is abnormally close to the antenna, which may cause damage to the antenna; or a sound can be emitted to scare the creature away.

[0095] By building in temperature sensors and humidity sensors into the sensing module, it is possible to identify whether the antenna's operating temperature and humidity are normal. If the temperature or humidity exceeds or falls below a certain set threshold, an early warning message will be sent back to inform the user that the temperature or humidity is abnormal.

[0096] By building a gyroscope and acceleration sensor into the sensing module, it is possible to identify whether the antenna is abnormally displaced. If the antenna is abnormally displaced, an early warning message can be sent back to inform the user of the abnormal antenna displacement.

[0097] By building infrared sensors, temperature sensors, humidity sensors, acceleration sensors, gyroscopes and other devices into the sensing module, the working environment and working status of the antenna can be monitored in real time. When a network failure occurs, the fault point can be found more quickly, thereby improving network security and reliability.

[0098] The orientation detection module may include but is not limited to a global navigation satellite system (GNSS), an accelerometer, and a gyroscope. The GNSS may be used to determine the geographic location of the base station antenna system, or to obtain the three-dimensional coordinates of the antenna module 110 or the altitude of the location of the antenna module 110; the accelerometer and the gyroscope may be used to determine the downtilt angle and the roll angle of the antenna module 110.

[0099] It should be noted that the acceleration sensor, gyroscope and other devices in the orientation detection module can reuse the acceleration sensor, gyroscope and other devices in the environment detection module.

[0100] An accelerometer is a sensor that can measure the acceleration of an object. It can detect the change in acceleration of an object when it is in motion and convert it into an electrical signal for output. Common accelerometers include piezoelectric, capacitive, and micro-electromechanical systems (MEMS). When the antenna is not tilted or rotated, the three-axis accelerometer will only detect the acceleration of gravity. When the antenna is tilted or rotated, the acceleration of gravity will produce different projections on the three axes. By measuring the acceleration components on the three axes, the downtilt angle and roll angle of the antenna can be reversed.

[0101] A gyroscope is a device that senses and maintains direction based on the theory of conservation of angular momentum. A gyroscope is mainly composed of a rotatable rotor located at the axis. Due to the angular momentum of the rotor, once the gyroscope starts to rotate, it tends to resist changes in direction. A gyroscope has two basic characteristics: fixed axis and precession. The principle of a gyroscope to measure the downtilt and roll angle of an antenna is to use the fixed axis of the gyroscope to measure the rotation angle of the antenna relative to the inertial space, and then calculate the tilt angle and rotation angle of the antenna relative to the horizontal plane.

[0102] In some embodiments, the GNSS can also be used to measure the azimuth of the antenna module 110. Specifically, the azimuth of the antenna module 110 is calculated by the double difference of the phase of the radio frequency signals received by two GNSS at different positions. For example, the GNSS built into the sensing module 130 is recorded as the first GNSS, and the GNSS placed at another position is recorded as the second GNSS. The first GNSS and the second GNSS can receive signals from satellites and record the timestamps of when they receive the signals. Based on the difference between the propagation speeds of these signals and the timestamps, the distance from the satellite to the first GNSS and the second GNSS can be calculated. If the distance between the first GNSS and the second GNSS is known (which can be measured or known in advance), the geometric relationship of the triangle can be used to calculate the position of the antenna module 110. The azimuth of the antenna module 110 is calculated using the position of the antenna module 110 and the positions of the GPS satellites at other positions.

[0103] The first wireless backhaul module may generally include components such as a SIM card and an antenna, and may be connected to a wireless network and perform wireless data transmission with the antenna module 110 , thereby receiving control information or wireless backhaul measurement data and warning messages.

[0104] It should be noted that the control information may be, for example, a control message instructing the perception module 130 to perform measurement, or relevant control information for adjusting settings of the perception module.

[0105] In some embodiments, the sensing module 130 may not include the first wireless backhaul module, but may receive control information or wirelessly backhaul measurement data and warning messages through a cable.

[0106] It should be understood that the above-mentioned light emitting module, position detection module, environment detection module and wireless backhaul module are all optional modules.

Figure 5As shown, the antenna module 110 may include multiple antenna interfaces, and correspondingly, the RRU 120 may include multiple radio frequency (RF) interfaces. The antenna module 110 and the RRU 120 may communicate via the multiple antenna interfaces and the multiple RF interfaces.

[0110] By connecting AISG interface 1 and AISG interface 4, antenna module 110 can supply power to sensing module 130. Specifically, the signal transmitted by AISG interface may include RF signal and DC signal, and the bias circuit provided in sensing module 130 can separate the RF signal and DC signal, thereby obtaining the DC signal.

[0111] In the embodiment of the present application, after the sensing module 130 obtains the measurement data, the first wireless backhaul module can be used to wirelessly send the measurement data to the antenna module 110. The antenna module 110 can transmit the measurement data to the RRU 120 by wire through the AISG interface 2 and the AISG interface 3, and the RRU 120 then transmits the measurement data back to the server through the optical fiber.

[0112] In some embodiments, after the sensing module 130 obtains the measurement data, it can also transmit the measurement data to the antenna module 110 by wire through the AISG interface 4 and the AISG interface 1, for example, the measurement data can be carried by an on-off keying (OOK) signal. The antenna module 110 can transmit the measurement data to the RRU 120 by wire through the AISG interface 2 and the AISG interface 3, and the RRU 120 then transmits the measurement data back to the server through the optical fiber.

[0113] It should be noted that the server may be a server of the operator to which the antenna module 110 belongs.

[0114] It should be noted that if a solution of wired transmission of measurement data is selected, the sensing module 130 may be provided with a first wireless backhaul module or may not be provided with a first wireless backhaul module, which is not limited in the embodiment of the present application.

[0115] It should be understood that the above measurement data at least includes the first air pressure at the location where the antenna module 110 is located.

[0116] It should be understood that the embodiment of the present application utilizes the AISG interface existing in the existing base station antenna system to power each module in the perception module 130 and to realize data transmission, which can maximize compatibility with the original base station antenna system, thereby reducing the deployment cost of the perception module.

The air pressure sensor may be, for example, a barometer, a differential pressure gauge, or other device capable of measuring the atmospheric pressure, which is not limited in the present embodiment.

[0121] The second wireless backhaul module may include, for example, a SIM card, an antenna, and other components, and may be connected to a wireless network. Wireless data transmission may be performed between the second wireless backhaul module and the antenna module 110, thereby receiving control information or wireless backhaul measurement data. The measurement data may include, for example, a second air pressure at the location of the monitoring terminal 140.

[0122] It should be noted that the measurement data may be transmitted through the antenna module 110 to a server of an operator to which the antenna module 110 belongs.

[0123] It should be noted that the control information may be, for example, control information for instructing the monitoring terminal 140 to perform measurement, or relevant control information for adjusting settings of the monitoring terminal 140 .

[0124] In some embodiments, the monitoring terminal 140 may not include the second wireless backhaul module, but transmits the measurement data and receives the control information via wired transmission. For example, the monitoring terminal 140 may be connected to a device such as a BBU to transmit the measurement data back to the server of the operator to which the antenna module 110 belongs.

[0125] It should be noted that the monitoring terminal 140 may also include components necessary for maintaining operation, such as a power supply, a battery, etc., and may also include components such as a display screen to facilitate user operation.
