It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0013] As Figure 1 shown, in one embodiment, a method for satellite communication control for dynamically adjusting an antenna is proposed, which may specifically include the following steps: S101, monitoring and acquiring device status information of a mobile device; S102, determining a communication mode according to the device status information and the terrestrial network signal of the mobile device; S103, judging whether the communication mode is a satellite communication mode. If so, adjusting the parameters of all antennas to make them work in the satellite communication frequency band, and selecting a target antenna from all antennas to establish a communication link with a communication satellite; S104, calculating an ideal azimuth angle and an ideal elevation angle between the mobile device and the communication satellite according to the orbital data of the communication satellite and the current position of the mobile device; S105, selecting an antenna combination according to the ideal azimuth angle and the ideal elevation angle between the mobile device and the communication satellite to adjust the orientation of the main lobe of the antenna to make it approach the direction directly facing the communication satellite; S106, allocating power to each antenna in the selected antenna combination according to the ideal azimuth angle and the ideal elevation angle between the mobile device and the communication satellite.

[0014] In this embodiment, the device status information of the mobile device includes the sensing signals of the mobile device itself, such as a screen-off signal, a distance sensing signal, etc., and also includes the attitude measurement signals of the mobile device, such as a screen orientation signal, etc.

[0015] In this embodiment, the terrestrial network signal is a carrier network signal, including 2G, 3G, 4G, 5G, etc.

[0016] In this embodiment, adjusting the parameters of all antennas to make them work in the satellite communication frequency band, where the antennas refer to the antennas that form a communication link with the communication satellite. All the antennas mentioned in the present invention are the antennas that form a communication link with the communication satellite. The present invention does not involve the adjustment of the antennas required for the terrestrial network mode, so there is no need to mention it.

[0017] In this embodiment, the structural schematic diagram of all antennas is as Figure 2As shown, it is a phased array antenna. A phased array antenna is composed of multiple independent antennas (array elements). By adjusting the phase difference of the signals of each array element, electronic control of the beam direction is achieved. The target antenna is a part of the antennas selected from all the antennas.

[0018] In this embodiment, when establishing a communication link with a communication satellite, multiple target antennas can establish a communication link with the communication satellite, but there can only be one communication satellite.

[0019] In this embodiment, the azimuth angle refers to the angle between the projection line of the connection line aiming at the satellite by the main lobe axis of the antenna beam and the true north direction line when the true north is taken as zero degree and referenced in the clockwise direction; the elevation angle refers to the angle between the connection line of the main lobe beam axis of the antenna of the mobile device aiming at the satellite and its projection on the ground plane. In the ideal state, the actual azimuth angle is equal to the ideal azimuth angle, and the actual elevation angle is equal to the ideal elevation angle. Therefore, the ideal azimuth angle and the ideal elevation angle are calculated first.

[0020] In this embodiment, in S103, some antennas are selected, and in S105, some more antennas are selected to reduce the number of activated antennas while ensuring the connection between the mobile device and the communication satellite.

[0021] In this embodiment, in the communication system, the electric field pattern of the antenna is an important parameter, which describes the directivity of the electromagnetic wave radiated by the antenna. The main lobe is the most important part of the pattern, which represents the maximum radiation direction of the antenna. The size of the main lobe width will affect the coverage range and service quality of the communication system. During the communication with the communication satellite, the closer the central axis of the main lobe is to the connection line between the mobile device and the communication satellite (i.e., the direction directly facing the communication satellite), the better. S105 and S106 are the processes of implementing this step.

[0022] A method for satellite communication control of dynamically adjusting an antenna provided by an embodiment of the present invention monitors and obtains device status information of a mobile device; determines a communication mode according to the device status information and the ground network signal of the mobile device; determines whether the communication mode is a satellite communication mode, and if so, adjusts the parameters of all antennas to make them work in the satellite communication frequency band, selects a target antenna from all antennas to establish a communication link with a communication satellite; calculates an ideal azimuth angle and an ideal elevation angle between the mobile device and the communication satellite according to the orbital data of the communication satellite and the current position of the mobile device; selects an antenna combination according to the ideal azimuth angle and the ideal elevation angle between the mobile device and the communication satellite to adjust the orientation of the main lobe of the antenna to make it approach the direction directly facing the communication satellite; and allocates power to each antenna in the selected antenna combination according to the ideal azimuth angle and the ideal elevation angle between the mobile device and the communication satellite. By doing so, during the satellite communication process of the mobile device, some antennas are selected to be turned on according to the ideal azimuth angle and the ideal elevation angle between the mobile device and the communication satellite to adjust the orientation of the main lobe of the antenna to make it approach the direction directly facing the communication satellite while reducing the number of enabled antennas, and the power of each antenna is adjusted to adjust the orientation of the main lobe of the antenna to make it approach the direction directly facing the communication satellite while reducing the total power, thus solving the problems of high communication energy consumption and weak battery life of the mobile device during the satellite communication process.

[0023] In one embodiment, the determining the communication mode according to the device status information and the ground network signal of the mobile device includes: Obtaining a screen-off signal, a screen orientation signal, and a proximity sensor signal of the mobile device from the device status information; Determining whether the screen-off signal is 1, and if so, setting the status of the mobile device to the unused state, and if not, obtaining the screen orientation signal in the motion posture; Determining whether the screen orientation signal is not downward, and if so, determining whether the signal strength of the proximity sensor signal is greater than a first preset value, and if so, setting the status of the mobile device to the used state; If the signal strength of the proximity sensor signal is less than or equal to the first preset value, setting the status of the mobile device to the unused state; If the screen orientation signal is not not downward, setting the status of the mobile device to the unused state; Determining whether the device is in the used state, and if so, detecting the ground network signal of the mobile device and determining the communication mode according to the ground network signal of the mobile device, and if not, continuing to use the original communication mode.

[0024] In this embodiment, a screen-off signal of 1 indicates that the mobile device is in the screen-off state, at this time the user does not operate the mobile device, so there is no need to set the communication mode of the mobile device.

[0025] In this embodiment, the screen orientation signal can be obtained by an attitude measurement sensor such as a gravity sensor. If the screen orientation signal is not downward, it means that the screen orientation can be upward, left, right, etc. If the screen orientation signal is not not downward, it means that the screen orientation is downward, and at this time the mobile device is most likely in an unused state.

[0026] In this embodiment, the distance sensing signal can be a human body sensing signal such as an infrared sensing signal, which is obtained by a human body sensing sensor such as an infrared sensor, and the purpose is to detect whether the mobile device is in the user's hand. Therefore, the first preset value can be set to a value slightly smaller than the signal strength of the distance sensing signal when the mobile device is in the user's hand. When the signal strength of the distance sensing signal is less than or equal to the first preset value, it indicates that the mobile device may be in a space such as a pocket or a wallet, and these spaces will shield part of the human body heat sensing signal.

[0027] In one embodiment, determining the communication mode according to the terrestrial network signal of the mobile device includes: Obtaining the signal strengths of at least two specifications of signals in the terrestrial network signal; Judging whether the signal strengths of the obtained specification signals are all less than or equal to a second preset value. If not, the communication mode is determined to be the terrestrial network mode. If so, then Obtaining the signal quality value of the terrestrial network; Judging whether the signal quality value of the terrestrial network is greater than a third preset value. If so, the communication mode is determined to be the terrestrial network mode. If not, the communication mode is determined to be the satellite communication mode; where n is the number of specification signals obtained, i is the serial number of the obtained specification signal, a i is the proportionality coefficient corresponding to the i-th specification signal, and B i is the signal strength of the i-th specification signal.

[0028] In this embodiment, the specification signals include 2G signals, 3G signals, 4G signals, 5G signals, etc. The present invention preferentially selects the signal strengths of 4G signals and 5G signals.

[0029] In this embodiment, the signal strength of the terrestrial network signal is generally between -30 dBM and -80 dBm, and when it is -35 dBM, it is regarded as a very good signal strength. Therefore, the second preset value can be set to -40 dBm. If the signal strengths of the obtained specification signals are not all less than or equal to the second preset value, that is, the signal strength of any one specification is greater than the second preset value, the communication mode is directly determined to be the terrestrial network mode.

[0030] In this embodiment, the third preset value can be set to -60 dBm.

[0031] In this embodiment, ai The sum is 1, and a i can be set to , for example, when n is 2, both a1 and a2 are set to 0.5.

[0032] In one embodiment, selecting a target antenna from all antennas to establish a communication link with a communication satellite includes: For each antenna, enable the antenna separately and determine the communication satellite X paired with the antenna; For each communication satellite X, determine whether the signal strength between the antenna and the communication satellite is greater than a fourth preset value. If so, increment the weight value of the communication satellite X by 1; For the communication satellite, by obtain the display ratio of the communication satellite; Determine the communication satellite with the largest display ratio as the target satellite; Determine the antenna paired with the target satellite as the target antenna; Establish a communication link between the target antenna and the target satellite; wherein, the initial value of the weight value of each communication satellite is 0, b is the weight value of the communication satellite, and N is the total number of communication satellites.

[0033] In this embodiment, when the signal strength of the communication satellite is between -40 dBm and -60 dBm, it is a good connection state. Therefore, the fourth preset value can be set to -60 dBm.

[0034] In this embodiment, the target antenna is the result of the first screening.

[0035] In one embodiment, calculating the ideal azimuth angle and ideal elevation angle between the mobile device and the communication satellite according to the orbital data of the communication satellite and the current position of the mobile device includes: Receive the navigation message of the communication satellite and obtain the orbital data of the communication satellite from the navigation message; Obtain the longitude and latitude of the communication satellite according to the orbital data of the communication satellite; Obtain the longitude and latitude of the current position of the mobile device; From obtain the ideal azimuth angle between the mobile device and the communication satellite; From obtain the ideal elevation angle between the mobile device and the communication satellite; wherein, is the longitude of the communication satellite, is the longitude of the current position of the mobile device, is the latitude of the communication satellite.

[0036] In this embodiment, the communication satellite broadcasts navigation messages containing its own position information, such as orbital data like satellite orbit ephemeris. The navigation messages are broadcast, and can be obtained without the need for the communication satellite to communicate with the mobile device.

[0037] In this embodiment, obtaining the longitude and latitude of the communication satellite based on the orbital data of the communication satellite is a common technology and will not be elaborated here.

[0038] In this embodiment, the longitude and latitude of the current position of the mobile device are usually obtained by means of GPS positioning.

[0039] In one embodiment, the selection of the antenna combination according to the ideal azimuth angle and ideal elevation angle between the mobile device and the communication satellite to adjust the orientation of the antenna main lobe to make it approach the direction directly facing the communication satellite includes: Determine the target antenna for establishing a communication link with the communication satellite; Determine all antenna combinations according to the target antenna; For each antenna combination, turn off the antennas outside the antenna combination; From Obtain the combined field strength of the antenna combination; Determine the beam direction of the antenna main lobe of the antenna combination according to the combined field strength of the antenna combination; Determine the actual direction angle and actual elevation angle of the antenna main lobe of the antenna combination according to the beam direction of the antenna main lobe of the antenna combination; From Obtain the first deviation value of the antenna combination; Select the antenna combination with the smallest first deviation value; Update the target antenna according to the antennas in the selected antenna combination to adjust the orientation of the antenna main lobe to make it approach the direction directly facing the communication satellite; where m is the number of antennas in the antenna combination, k is the serial number of the antenna in the antenna combination, E k is the electric field amplitude of the k-th antenna, is the phase offset of the k-th antenna, j is the imaginary part, is the phase rotation factor of the k-th antenna, u k is the unit vector of the polarization direction of the k-th antenna, K1 is the first direction angle coefficient, K2 is the first elevation angle coefficient, A z0 is the ideal azimuth angle between the mobile device and the communication satellite, A z1 is the actual direction angle of the antenna main lobe of the antenna combination, EL0 is the ideal elevation angle between the mobile device and the communication satellite, and EL1 is the actual elevation angle of the antenna main lobe of the antenna combination.

[0040] In this embodiment, determining all antenna combinations based on the target antenna means obtaining all antenna combinations by using a combinatorial mathematical method. Here, the total number of combinatorial mathematical methods is any number from 1 to the number of target antennas, and all numbers from 1 to the number of target antennas need to be traversed. Traversal is a computer term, which means that all numerical values are walked through once. For example, if the number of target antennas is 3, then all cases with a total number of 1, 2, and 3 need to be traversed through the combinatorial mathematical method to obtain all antenna combinations.

[0041] In this embodiment, as Figure 3 shown, in a communication system, the electric field pattern of an antenna is an important parameter, which describes the directivity of the electromagnetic wave radiated by the antenna, and there are main lobes and side lobes. The combined electric field strength is the manifestation form after the superposition of the electric field patterns of multiple antennas, and it is also an electric field pattern. Therefore, there are also main lobes. As Figure 3 shown, the main lobe is the area with the strongest coverage of the antenna. Therefore, determining the beam pointing of the antenna main lobe of the antenna combination based on the combined electric field strength of the antenna combination is to find the central axis of the area with the best signal strength in the combined electric field strength.

[0042] In this embodiment, based on the beam pointing of the antenna main lobe of the antenna combination, determining the actual direction angle and actual elevation angle of the antenna main lobe of the antenna combination. After determining the central axis of the area with the best signal strength in the combined electric field strength, the actual direction angle and actual elevation angle of the antenna main lobe of the antenna combination can be determined according to the central axis. At this time, the beam pointing of the antenna main lobe of the antenna combination is clear, and a three-dimensional space coordinate system can be established to reflect the beam pointing of the antenna main lobe of the antenna combination in the three-dimensional space coordinate system. At the same time, reflecting the true north direction line and the ground plane in the three-dimensional space coordinate system, so that the actual direction angle and actual elevation angle of the antenna main lobe of the antenna combination can be obtained.

[0043] In this embodiment, selecting the antenna combination with the smallest first deviation value is the second screening of the target antenna. After updating the target antenna according to the antennas in the selected antenna combination, any target antenna that is not in the antenna combination with the smallest first deviation value is no longer a target antenna.

[0044] In one embodiment, allocating power to each antenna in the selected antenna combination according to the ideal azimuth angle and ideal elevation angle between the mobile device and the communication satellite includes: Sorting the antennas in the selected antenna combination to obtain all sorting combinations; For each antenna in the sorted combination of antennas, allocate power to the antennas within the sorted combination; Calculate the combined electric field strength of the sorted combination after power allocation; Determine the beam pointing of the antenna main lobe of the sorted combination according to the combined electric field strength of the sorted combination; Determine the actual direction angle and actual elevation angle of the main lobe of the antenna for this sorting combination based on the beam pointing of the main lobe of the antenna for this sorting combination; From Obtain the second deviation value for this sorting combination; Select the power adjustment result corresponding to the sorting combination with the smallest second deviation value and allocate power to each antenna in the selected antenna combination; Where P is the total power of the mobile device for the satellite communication mode, M is the number of antennas in this sorting combination, x is the serial number of the antenna in this sorting combination, c is the decreasing ratio, K3 is the second direction angle coefficient, K4 is the second elevation angle coefficient, A z0 is the ideal azimuth angle between the mobile device and the communication satellite, A z2 is the actual direction angle of the main lobe of the antenna for this sorting combination, EL0 is the ideal elevation angle between the mobile device and the communication satellite, and EL2 is the actual elevation angle of the main lobe of the antenna for this sorting combination.

[0045] In this embodiment, What is obtained is the average power that the total power of the mobile device for the satellite communication mode can be allocated to the antennas in the permutation combination, and c can be set to 5% or 10%.

[0046] In this embodiment, the steps of calculating the combined field strength of this sorting combination after power allocation and from The steps of obtaining the combined field strength of the antenna combination are the same.

[0047] In this embodiment, determining the beam pointing of the main lobe of the antenna for this sorting combination based on the combined field strength of this sorting combination, and determining the actual direction angle and actual elevation angle of the main lobe of the antenna for this sorting combination based on the beam pointing of the main lobe of the antenna for this sorting combination are the same as those of the antenna combination method, and will not be elaborated here.

[0048] In this embodiment, the power density is proportional to the square of the electric field strength, that is , where S is the power density, E is the electric field strength, and Z0 is the free space wave impedance. Therefore, the shape of the power pattern is similar to that of the electric field pattern, but the widths of the main lobe and side lobes are narrower (because the square operation will compress the low-intensity region). Therefore, if the power of the antennas near the main lobe direction in the original antenna combination is increased and the power of the antennas near the side lobe direction is decreased, it can have a certain impact on the combined field strength and make the beam pointing of the main lobe of the antenna for this sorting combination approach the direction directly facing the communication satellite.

[0049] In one embodiment, the method for dynamically adjusting the satellite communication control of the antenna further includes: Monitor the signal strength of the mobile device for the communication satellite; Determine whether the signal strength of the mobile device with respect to the communication satellite is less than the fifth preset value. If so, select a new target antenna from all the antennas to establish a communication link with the new communication satellite and execute S104 - S106; If the signal strength of the mobile device with respect to the communication satellite is greater than or equal to the fifth preset value, determine whether the real - time change rate of the signal strength of the mobile device with respect to the communication satellite is less than the sixth preset value. If so, select a new target antenna from all the antennas to establish a communication link with the new communication satellite and execute S104 - S106. If not, do nothing.

[0050] In this embodiment, the fifth preset value can be set to - 60 dBm.

[0051] In this embodiment, normally, the signal strength of the mobile device with respect to the communication satellite does not change much. Once a rapid decline occurs, it is necessary to re - determine the antenna combination. At this time, it is not required that the signal strength of the mobile device with respect to the communication satellite is less than the fifth preset value, because the reason for the decline may be that the connected communication satellite has moved too far from the position calculated last time or the mobile device has moved to another location and needs to change the connected communication satellite or the target antenna. The sixth preset value can be set to - 10 dBm / s.
