Description

Technical Field

[0001] The present application relates to satellite alignment technology in satellite communications, and more particularly to a satellite communications method, device, electronic equipment and computer storage medium. Background Art

[0002] At present, satellite communication, used as a base station or relay station to achieve communication, is a communication technology that has suddenly become popular in recent years. Due to its good coverage of the earth's surface in sparsely populated areas such as non-land, remote mountainous areas, and polar regions, satellite communication will become one of the hot technologies for the next generation of mobile communications. Judging from the current development trend, more and more technology companies are joining the satellite communication industry chain. Figure 1 is the network topology of the satellite communication system in the related technology, such as Figure 1 As shown, it includes: a mobile phone, a satellite, a gateway, a base station 1, a base station 2 and a fifth generation mobile communication technology (5G) core network. In satellite communication, the mobile phone is aimed at the satellite, the satellite communicates with the base station 1 through the gateway, and the base station 1 communicates with the 5G core network. In wireless communication, the mobile phone communicates directly with the base station 2, and the base station 2 communicates with the 5G core network.

[0003] Since satellites used for satellite communications are hundreds to tens of thousands of kilometers above the earth, the long distance causes communication signals to attenuate greatly. At the same time, the radiation direction of the mobile phone antenna is usually not a completely regular spherical radiation pattern. At the same distance, the energy in the direction of the antenna's maximum radiation pattern is significantly larger than in other directions. In order to obtain high-quality communication effects, it is usually necessary to point the mobile phone's maximum radiation direction toward the satellite. In this way, the signal strength of the signal transmitted by the mobile phone is the greatest when it reaches the satellite. Signal strength is one of the most important parameters for communication quality. Figure 2 is the radiation waveform diagram of a certain antenna of a mobile phone in the related technology, such as Figure 2 As shown, -15 to -5 represents a signal change from weak to strong.

[0004] However, the related technology only considers the radiation pattern of free space, and uses this default radiation pattern of free space to extract the maximum radiation direction parameter as the basic data for satellite alignment operation during satellite communication. However, in actual use, because the user holds the mobile phone in his hand, it will affect the radiation pattern of the mobile phone, including causing the radiation direction and radiation power of the mobile phone to change; it can be seen that the maximum radiation direction when the human hand holds the mobile phone is different from the maximum radiation direction in free space. At the same time, because the human hand is a non-transparent medium, it will absorb part of the antenna radiation energy, resulting in the energy of the antenna in the maximum radiation direction is also lower than that of the free space. Therefore, there is a difference between the actual direction of the user holding the mobile phone for satellite alignment and the ideal direction (the ideal direction refers to the actual maximum direction corresponding to the user holding the mobile phone) and the power size, resulting in the communication between the mobile phone and the satellite not reaching the optimal state; it can be seen that the existing satellite alignment method of electronic equipment leads to the technical problem of poor communication quality when the electronic equipment performs satellite communication.

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] In related technologies, the satellite tracking method can be divided into three steps: first, the radiation field pattern of the mobile phone is obtained through Over The Air (OTA) testing, and then the maximum radiation direction of the mobile phone is obtained. Then, by pre-downloading the satellite's ephemeris information, the spatial position of the target satellite can be guided. The position, orientation, tilt angle, and movement direction of the mobile phone can be obtained through the mobile phone's built-in Global Navigation Satellite System (GNSS) compass / gyroscope / acceleration sensor and other sensors.

[0036] After obtaining the above information, the sensor transmits the perceived parameters to the central processing unit (CPU) in the electronic device, and the CPU transmits the relevant information to the application (APP) of the electronic device. The user interface (UI) on the APP guides the user to perform satellite alignment operations (for example, adjusting the posture / direction / orientation of the mobile phone, etc.), point the maximum radiation direction of the mobile phone to the satellite in the sky, complete the satellite alignment operation, and obtain the best communication quality.

[0037] Figure 3 is a block diagram of a radio frequency system of a satellite communication terminal in the related art, such as Figure 3 As shown, the RF system 300 may include: a transceiver 31, a power amplifier (PA) 32, a feedback receiving path (FBRX) low noise amplifier (LNA) 33, a receiving path (RX) low noise amplifier (LNA) 34, a transmit and receive switching switch 35, a directional coupler 36, a CPU 37 (for Trigger signal), a sensor module 38 and a satellite communication antenna 39.

[0038] However, in the related art, when electronic devices are aligned with satellites, they only consider the radiation pattern of free space, and use this default radiation pattern of free space to extract the maximum radiation direction parameter as the alignment parameter for satellite communication. However, in actual use, because the user holds the mobile phone in his hand, it will affect the radiation pattern of the mobile phone. The impact here includes changes in the radiation direction and radiation power of the mobile phone. There is a difference between the maximum radiation direction when the human hand holds the mobile phone and the maximum radiation direction in free space. At the same time, because the human hand is a non-transparent medium, it will absorb part of the antenna radiation energy, resulting in the energy of the antenna in the maximum radiation direction being lower than that in free space. Therefore, when the user holds the mobile phone in his hand for alignment, there is a difference between the actual direction and the ideal direction (the ideal direction refers to the actual maximum radiation direction corresponding to the user holding the mobile phone) and the power size, resulting in the communication between the mobile phone and the satellite not reaching the optimal state.

[0039] The present application embodiment provides a satellite communication method, which is applied in an electronic device. Figure 4 A schematic diagram of a flow chart of an optional satellite communication method provided in an embodiment of the present application, such as Figure 4 As shown, the satellite communication method may include:

[0040] S401: Determine a holding state of the electronic device;

[0041] When an electronic device needs to dock with a satellite through a satellite communication antenna to achieve satellite communication, in order to reduce the problem of poor communication quality caused by the mobile phone being held, the electronic device first determines the holding state of the electronic device. It should be noted that the holding state here usually refers to the holding state of a human hand, so the holding state here can include a left-hand holding state and a right-hand holding state.

[0042] Here, the electronic device may determine the holding state of the electronic device through a non-satellite communication antenna, wherein the non-satellite communication antenna may be a cellular antenna or a Wireless Fidelity (Wi-Fi) antenna, and the embodiments of the present application do not specifically limit this.

[0043] Among them, the above-mentioned non-satellite communication antenna can be one or more, and this embodiment of the present application does not make any specific limitation on this.

[0044] S402: Determine compensation parameters corresponding to the holding state;

[0045] After the electronic device determines the holding state of the electronic device, since the correspondence between the holding state and the compensation parameters is stored in the electronic device, the compensation parameters corresponding to the holding state of the electronic device can be determined based on the correspondence, wherein there are compensation parameters corresponding to the left-hand holding state and there are compensation parameters corresponding to the right-hand holding state. In this way, compensation can be achieved according to the compensation parameters corresponding to different holding states.

[0046] In this way, the holding state of the electronic device is matched one-to-one with the compensation parameters in advance, so that the compensation parameters are related to the holding state. Compensation is performed based on this, and the satellite parameters can be optimized, so that the satellite communication antenna of the electronic device can be docked with the satellite, and communicate with the satellite through the satellite communication antenna, thereby improving the communication quality of the electronic device performing satellite communication.

[0047] S403: using the compensation parameter corresponding to the holding state, compensating at least one parameter of the alignment parameters of the current radiation direction in the holding state to obtain the alignment parameter corresponding to the holding state;

[0048] The satellite alignment parameters corresponding to the holding state may include the following three parameters: effective isotropically radiated power (EIRP) (also denoted as r), azimuth angle θ and elevation angle .

[0049] That is to say, after obtaining the star alignment parameters corresponding to the holding state, since the electronic device can obtain the star alignment parameters of the current radiation direction in the holding state, the compensation parameters corresponding to the holding state can be used to compensate at least one of the star alignment parameters in the current radiation direction, thereby obtaining the star alignment parameters corresponding to the holding state.

[0050] Here, the compensation parameters corresponding to the holding state can be used to compensate r in the star alignment parameter of the current radiation direction, and the compensation parameters corresponding to the holding state can also be used to compensate θ in the star alignment parameter of the current radiation direction, and the compensation parameters corresponding to the holding state can also be used to compensate θ in the star alignment parameter of the current radiation direction. The compensation parameters corresponding to the holding state can be used to compensate for r and θ in the star alignment parameters of the current radiation direction. The compensation parameters corresponding to the holding state can be used to compensate for r and θ in the star alignment parameters of the current radiation direction. The compensation parameters corresponding to the holding state can also be used to compensate for the θ and The compensation parameters corresponding to the holding state can also be used to compensate for the r, θ and Compensation is performed, and this embodiment of the present application does not make any specific limitation on this.

[0051] The satellite alignment parameters corresponding to the holding state are used to connect the satellite communication antenna in the electronic device with the satellite, so that the electronic device can perform satellite communication through the satellite; that is, after obtaining the satellite alignment parameters corresponding to the holding state, the electronic device can adjust the transmission power based on r in the satellite alignment parameters corresponding to the holding state, and can adjust the transmission power based on θ and , so that the APP prompts the user to turn the phone until it is docked with the satellite to achieve satellite communication.

[0052] In order to determine the holding state of the electronic device, in an optional embodiment, the electronic device includes: a non-satellite communication antenna, and correspondingly, S401 may include:

[0053] determining a holding state of the electronic device based on performance parameters of the non-satellite communication antenna;

[0054] It can be understood that here, the non-satellite communication antenna is tested to obtain the performance parameters of the non-satellite communication antenna, so that the holding state of the electronic device is determined based on the performance parameters of the non-satellite communication antenna.

[0055] Among them, the performance parameters of the above-mentioned non-satellite antenna may include one or more of the following: standing wave ratio and S parameters. That is to say, the holding state of the electronic device can be determined based on the standing wave ratio of the non-satellite communication antenna, or based on the S parameters of the non-satellite communication antenna. Of course, the holding state of the electronic device can also be determined based on the standing wave ratio and S parameters of the non-satellite communication antenna. Here, the embodiment of the present application does not make specific limitations on this.

[0056] Among them, the holding state includes: left-hand holding state and right-hand holding state. That is to say, there are compensation parameters corresponding to the left-hand holding state and compensation parameters corresponding to the right-hand holding state. Then, for different holding states, different compensation parameters will be used to compensate one or more parameters in the satellite parameters in the current radiation direction, so as to use the compensated parameters to dock with the satellite, thereby realizing satellite communication and improving the quality of satellite communication.

[0057] Further, in order to determine the holding state of the electronic device, in an optional embodiment, the non-satellite communication antenna includes a first non-satellite communication antenna, and the first non-satellite communication antenna is located on a first side frame of the electronic device. Correspondingly, based on the performance parameters of the non-satellite communication antenna, determining the holding state of the electronic device may include:

[0058] When the standing wave ratio of the first non-satellite communication antenna falls within a preset first standing wave ratio range, determining that the holding state of the electronic device is a left-hand holding state;

[0059] When the standing wave ratio of the first non-satellite communication antenna falls within a preset second standing wave ratio range, it is determined that the holding state of the electronic device is a right-hand holding state.

[0060] It can be understood that when the non-satellite communication antenna includes a first non-satellite communication antenna located on the first side frame of the electronic device, the first side frame is a frame located on the left hand side of the user when the screen of the electronic device faces the user. When the electronic device is held in the left hand, the first side frame will be held by the palm of the left hand, so the standing wave ratio of the first non-satellite antenna will change at this time. Here, the standing wave ratio can be used to determine the holding state of the electronic device.

[0061] When the standing wave ratio of the first non-satellite communication antenna falls within a preset first standing wave ratio range, it is determined that the holding state of the electronic device is a left-hand holding state, wherein the preset first standing wave ratio range is a standing wave ratio range of the first non-satellite communication antenna when held by the left hand that is determined in advance.

[0062] When the standing wave ratio of the first non-satellite communication antenna falls within a preset second standing wave ratio range, it is determined that the holding state of the electronic device is a right-hand holding state, wherein the preset second standing wave ratio range is a standing wave ratio range of the first non-satellite communication antenna when held in the right hand that is determined in advance.

[0063] In this way, the holding state of the electronic device can be determined by the standing wave ratio range within which the standing wave ratio of the first non-satellite communication antenna falls, and then the compensation parameters corresponding to the holding state can be determined based on the above correspondence to compensate for the satellite parameters in the current radiation direction when the electronic device is in the holding state, thereby optimizing the docking between the satellite communication antenna and the satellite and improving the communication quality of the satellite communication.

[0064] In addition, in order to determine the holding state based on the S parameters of the first non-satellite communication antenna, in an optional embodiment, the non-satellite communication antenna includes a first non-satellite communication antenna, and the first non-satellite communication antenna is located on a first side frame of the electronic device. Correspondingly, based on the performance parameters of the non-satellite communication antenna, determining the holding state of the electronic device may include:

[0065] When the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset first frequency range, determining that the holding state of the electronic device is a left-hand holding state;

[0066] When the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset second frequency range, it is determined that the holding state of the electronic device is a right-hand holding state.

[0067] It can be understood that when the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset first frequency range, the holding state of the electronic device is determined to be a left-hand holding state, and the preset first frequency range is a range of the maximum value of the S parameter of the first non-satellite communication antenna determined in advance when the left hand is held.

[0068] When the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset second frequency range, it is determined that the holding state of the electronic device is a right-hand holding state, and the preset second frequency range is a range of the maximum value of the S parameter of the first non-satellite communication antenna determined in advance when held in the right hand.

[0069] In this way, the holding state of the electronic device can be determined by the frequency range within which the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls, and then the compensation parameters corresponding to the holding state can be determined based on the above correspondence to compensate for the satellite parameters in the current radiation direction when the electronic device is in the holding state, thereby optimizing the docking between the satellite communication antenna and the satellite and improving the communication quality of the satellite communication.

[0070] It should be noted that the holding state of the electronic device can also be determined based on the frequency corresponding to the maximum value of the standing wave ratio and the S parameter of the first non-satellite communication antenna. Here, the embodiment of the present application does not make specific limitations on this.

[0071] When the non-satellite communication antenna includes two antennas, in an optional embodiment, the non-satellite communication antenna includes a second non-satellite communication antenna, and the second non-satellite communication antenna is located on a second side frame of the electronic device. Accordingly, determining the holding state of the electronic device based on the performance parameters of the non-satellite communication antenna may include:

[0072] When the standing wave ratio of the first non-satellite communication antenna falls within a preset first standing wave ratio range, and the standing wave ratio of the second non-satellite communication antenna falls within a preset third standing wave ratio range, determining that the holding state of the electronic device is a left-hand holding state;

[0073] When the standing wave ratio of the first non-satellite communication antenna falls within a preset second standing wave ratio range, and the standing wave ratio of the second non-satellite communication antenna falls within a preset fourth standing wave ratio range, it is determined that the holding state of the electronic device is a right-hand holding state.

[0074] It can be understood that the non-satellite communication antenna includes, in addition to the above-mentioned first non-satellite communication antenna, a second non-satellite communication antenna, and the second non-satellite antenna is located on the second side frame, which is the frame located on the right hand side of the user when the screen of the electronic device faces the user. When the electronic device is held in the right hand, the second side frame will be held by the palm of the right hand. Therefore, under different holding states, the standing wave ratio of the first non-satellite communication antenna and the second non-satellite antenna will change, but the changes are different. Here, the standing wave ratio of the two antennas can be used to determine the holding state.

[0075] When the standing wave ratio of the first non-satellite communication antenna falls within a preset first standing wave ratio range, and the standing wave ratio of the second non-satellite communication antenna falls within a preset third standing wave ratio range, it is determined that the holding state of the electronic device is a left-hand holding state, and the preset third standing wave ratio range is a standing wave ratio range of the second non-satellite communication antenna when the left hand is held in advance.

[0076] When the standing wave ratio of the first non-satellite communication antenna falls within a preset second standing wave ratio range, and the standing wave ratio of the second non-satellite communication antenna falls within a preset fourth standing wave ratio range, it is determined that the holding state of the electronic device is a right-hand holding state, and the preset fourth standing wave ratio range is a standing wave ratio range of the second non-satellite communication antenna when held in the right hand in advance.

[0077] In this way, the holding state of the electronic device can be determined by the standing wave ratio range within which the standing wave ratios of the first non-satellite communication antenna and the second non-satellite communication antenna fall, and then the compensation parameters corresponding to the holding state can be determined to compensate for the satellite parameters in the current radiation direction when the electronic device is in the holding state, thereby optimizing the docking between the satellite communication antenna and the satellite and improving the communication quality of the satellite communication.

[0078] With respect to determining the holding state of the electronic device by using the frequency corresponding to the maximum value of the S parameters of the two antennas, in an optional embodiment, the non-satellite communication antenna includes a second non-satellite communication antenna, and the second non-satellite communication antenna is located on the second side frame of the electronic device. Correspondingly, determining the holding state of the electronic device based on the performance parameters of the non-satellite communication antenna may include:

[0079] When the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset first frequency range, and the frequency corresponding to the maximum value of the S parameter of the second non-satellite communication antenna falls within a preset third frequency range, determining that the holding state of the electronic device is a left-hand holding state;

[0080] When the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset second frequency range, and the frequency corresponding to the maximum value of the S parameter of the second non-satellite communication antenna falls within a preset fourth frequency range, it is determined that the holding state of the electronic device is a right-hand holding state.

[0081] It can be understood that in addition to the above-mentioned first non-satellite communication antenna, the non-satellite communication antenna also includes a second non-satellite communication antenna, and the second non-satellite antenna is located on the second side frame, which is the frame located on the right hand side of the user when the screen of the electronic device faces the user. When the electronic device is held in the right hand, the second side frame will be held by the right palm. Therefore, in different holding states, the frequencies corresponding to the maximum values ​​of the S parameters of the first non-satellite communication antenna and the second non-satellite antenna will change, but the changes are different. Here, the frequencies corresponding to the maximum values ​​of the S parameters of the two antennas can be used to determine the holding state of the electronic device.

[0082] When the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset first frequency range, and the frequency corresponding to the maximum value of the S parameter of the second non-satellite communication antenna falls within a preset third frequency range, it is determined that the holding state of the electronic device is a left-hand holding state, and the preset third frequency range is a frequency range corresponding to the maximum value of the S parameter of the second non-satellite communication antenna when the left hand is held.

[0083] When the frequency corresponding to the maximum value of the S parameter of the first non-satellite communication antenna falls within a preset second frequency range, and the frequency corresponding to the maximum value of the S parameter of the second non-satellite communication antenna falls within a preset fourth frequency range, it is determined that the holding state of the electronic device is a right-hand holding state, and the preset fourth frequency range is a frequency range corresponding to the maximum value of the S parameter of the second non-satellite communication antenna when held in the right hand in advance.

[0084] In this way, the holding state of the electronic device can be determined by the frequency range within which the frequency corresponding to the maximum value of the S parameters of the first non-satellite communication antenna and the second non-satellite communication antenna falls, and then the compensation parameters corresponding to the holding state can be determined to compensate for the satellite parameters in the current radiation direction when the electronic device is in the holding state, thereby optimizing the docking between the satellite communication antenna and the satellite and improving the communication quality of the satellite communication.

[0085] Here, it should be noted that the compensation parameters corresponding to the holding state can be pre-stored in the electronic device, and the electronic device can directly obtain them when compensation is needed. Therefore, in order to obtain the compensation parameters corresponding to the holding state in advance, in an optional embodiment, the method further includes:

[0086] Obtaining the alignment parameters of the maximum radiation direction of the satellite communication antenna in free space, the alignment parameters of the maximum radiation direction of the satellite communication antenna when the satellite communication antenna is held in the left hand, and the alignment parameters of the maximum radiation direction of the satellite communication antenna when the satellite communication antenna is held in the right hand;

[0087] By obtaining the alignment parameters of the maximum radiation direction of the satellite communication antenna in free space and the alignment parameters of the maximum radiation direction of the satellite communication antenna in the left-hand holding state, the compensation parameters corresponding to the left-hand holding state are determined;

[0088] Compensation parameters corresponding to the right-hand holding state are determined by using the satellite communication antenna's alignment parameters of the maximum radiation direction in free space and the satellite communication antenna's alignment parameters of the maximum radiation direction in the right-hand holding state.

[0089] It can be understood that the electronic device first obtains the satellite alignment parameters of the maximum radiation direction of the satellite communication antenna in three states, wherein the three states are free space, left-hand holding state and right-hand holding state, that is, the satellite alignment parameters of the maximum radiation direction of the satellite communication antenna in free space are recorded as (r1, θ1, ), the satellite communication antenna's maximum radiation direction when held in the left hand is recorded as (r2, θ2, ) and the satellite communication antenna's maximum radiation direction in the right hand holding state is recorded as (r3, θ3, ).

[0090] Here, after obtaining the above three sets of data, the difference between the satellite communication antenna's maximum radiation direction in free space and the satellite communication antenna's maximum radiation direction in the left hand holding state can be obtained by subtracting the difference between (r1-r2, θ1-θ2, ), which is the compensation parameter corresponding to the left hand holding state.

[0091] The difference between the satellite communication antenna's maximum radiation direction in free space and the satellite communication antenna's maximum radiation direction in the right hand holding state can be obtained by subtracting the difference between (r1-r3, θ1-θ3, ), which is the compensation parameter corresponding to the right hand holding state.

[0092] In this way, after obtaining the compensation parameters corresponding to the left-hand holding state and the compensation parameters corresponding to the right-hand holding state, the satellite alignment parameters corresponding to the holding state can be obtained by compensating the satellite alignment parameters in the current radiation direction to better achieve satellite communication.

[0093] In order to achieve docking with a satellite using more appropriate satellite alignment parameters, in an optional embodiment, the method further includes:

[0094] When the equivalent isotropic radiated power in the satellite alignment parameters corresponding to the holding state is greater than the current maximum transmit power of the satellite communication antenna, the current maximum transmit power of the satellite communication antenna is determined as the equivalent isotropic radiated power in the satellite alignment parameters corresponding to the holding state.

[0095] It can be understood that the maximum transmission power of the satellite communication antenna decreases as the antenna attenuates. Therefore, here, after determining the satellite alignment parameters corresponding to the holding state, the relationship between r in the satellite alignment parameters corresponding to the holding state and the current maximum transmission power of the satellite communication antenna is compared. If it is greater than, it means that the electronic device cannot use the r transmission power in the satellite alignment parameters corresponding to the holding state at this time. Therefore, here, the current maximum transmission power of the satellite communication antenna is determined as the equivalent isotropic radiated power in the satellite alignment parameters corresponding to the holding state, that is, the current maximum transmission power is used for transmission.

[0096] The satellite communication method in one or more of the above embodiments is described below with examples.

[0097] In the related technology, the holding state has a certain impact on satellite communication, and the current design of satellite communication terminals has a certain redundancy in output power (i.e., a certain margin can be adjusted), and the distance between the user's location and the satellite is not exactly the same. The different distances between the satellite and the terminal lead to different signal transmission losses. By adjusting the power, the ability of the PA can be fully utilized to achieve a balance between power consumption and communication quality.

[0098] In this example, a method is used to sense whether the current user is holding the satellite with the left hand or the right hand, and the influence of the holding hand is added to the angle of the satellite parameters (θ and / or ) or power (r) adjustment, the radiation direction deviation caused by hand holding and the automatic compensation of power can be achieved.

[0099] In the scenario of satellite communication, the mobile phone is not within the coverage of the cellular communication network. At this time, the cellular communication module of the mobile phone cannot search for external cellular network signals and is in an idle state. In addition, the antenna form of current mobile phones is basically a metal middle-frame antenna. Holding the mobile phone in hand will cause a significant decline in antenna performance. Figure 5 A schematic diagram of an optional human hand holding state provided in an embodiment of the present application, such as Figure 5 As shown, the user's left hand is holding the mobile phone, and the circle filled with cross lines is the position of the cellular antenna. It can be seen that when the left hand is holding the mobile phone, the circle is held; using Figure 3 The FBRX function in the device can sense the change in the antenna's standing wave ratio (VSWR), and thus know that one of the terminal's antennas is being held.

[0100] Based on the above Figure 5 , Figure 6 A schematic diagram of three radiation patterns of an optional cellular antenna provided in an embodiment of the present application, such as Figure 6 As shown above Figure 5 The three radiation patterns of the cellular antenna in the figure include: the maximum radiation direction in free space, the maximum radiation direction when held in the left hand, and the maximum radiation direction when held in the right hand. The origin of the coordinate system is the center of gravity of the mobile phone. It can be seen that there are different radiation patterns in the three states, which are different from each other.

[0101] Figure 7 An optional radio frequency system block diagram provided in an embodiment of the present application, such as Figure 7 As shown, the RF system 700 includes a RF link 71 of the left antenna, a RF path 72 of the right antenna and a satellite communication function module 73. The RF link 71 of the left antenna and the RF path 72 of the right antenna share a transceiver 74, and the transceiver 74 is connected to the CPU 75; wherein the RF link 71 of the left antenna may include: a power amplifier (PA) 711, a feedback receiving path (FBRX) low noise amplifier (LNA) 712, a receiving path (RX) low noise amplifier (LNA) 713, a transceiver switching switch 714, a directional coupler 715, and a left antenna 716; the RF link 72 of the right antenna may include: a power amplifier (PA) 721, a feedback receiving path (FBRX) low noise amplifier (LNA) 722, a receiving path (RX) low noise amplifier (LNA) 723, a transceiver switching switch 724, a directional coupler 725 and a right antenna 726; the left antenna is located at Figure 5 The right antenna is located on the left frame of the phone. Figure 5 The right frame of the mobile phone is a cellular antenna; based on the above Figure 7 , the satellite communication method may include:

[0102] Step A: First, hold the left and right antennas of the mobile phone in free space respectively. Through the bidirectional coupler of the RF front end (which can detect the reflected standing waves of the antenna and the transmitting power of the PA), the VSWR of the two antennas when they are held can be obtained respectively. Assuming that when they are not held, the standing wave ratio of the left antenna is A1, and the standing wave ratio of the right antenna is A2. When held with the left hand, the standing wave ratio of the left antenna is B1, and the standing wave ratio of the right antenna is B2. When held with the right hand, the standing wave ratio of the right antenna is C1, and the standing wave ratio of the right antenna is C2. In this way, it is possible to determine whether it is held in the left hand or the right hand based on the standing wave ratio range within which the standing wave ratios of the left and right antennas fall.

[0103] Step B: First, test the radiation pattern of the satellite communication antenna in three states: in free space, holding it with the left hand, and holding it with the right hand. Figure 8 A schematic diagram of a radiation pattern of an optional satellite communication antenna provided in an embodiment of the present application, such as Figure 8 As shown, there are three radiation field patterns of the above-mentioned satellite communication antenna, which may include: the maximum radiation direction in free space, the maximum radiation direction when held in the left hand, and the maximum radiation direction when held in the right hand, wherein the coordinate origin is the center of gravity of the terminal.

[0104] Step C: Define a 3D spherical coordinate system using EIRP (r), azimuth (θ) and elevation Fig. 9 A three-dimensional spherical coordinate system provided in the embodiment of the present application is as follows Fig. 9 As shown, M(r, θ, ) to describe any point on the sphere, the test results in step B will get the maximum power point coordinates M(r, θ, ).

[0105] Step D: Assume that the maximum power points obtained from the tests in free space, left hand holding, and right hand holding are (r1, θ1, ), (r2, θ2, ), (r3, θ3, ), Fig.10 A schematic diagram of an optional maximum power point provided in an embodiment of the present application, such as Fig.10 As shown, including θ1 and , the left hand holds the maximum radiation direction θ2 and .

[0106] Step E: Take the direction of the maximum radiated power point in free space (r1, θ1, ) as the reference, the power and angle differences between the maximum radiation direction of left-hand holding and right-hand holding and the maximum radiation direction of free space can be calculated respectively. Assuming that the left-hand holding coordinate angle difference (rL, θL, ), right hand holding coordinate angle difference (rR, θR, );

[0107] Here, rL=r1-r2, θL=θ1-θ2, ;rR=r1-r3, θR=θ1-θ3, .

[0108] Step F: Substitute (rL, θL, ), and (rR, θR, ) is stored in memory.

[0109] Step G: When the user actually uses the mobile phone to align the satellite, if the mobile phone detects that the user is holding the satellite in the left hand, the APP will automatically calculate the coordinate deviation (rL, θL, ) for the current radiation direction (r4, θ4, ) to compensate, then the star APP will guide the user to the direction (r4+rL, θ4+θL, ) to the star, so that the maximum direction when the user holds the phone in his left hand is the current maximum radiation direction of the phone (r4+rL, θ4+θL, ), rather than the default free space maximum radiation direction.

[0110] Step H: At the same time as step G, the transmitter will adjust the transmit power and increase the transmit power by rL, and implement closed-loop detection of the transmit power through the FBRX path to ensure that the current transmit power increment is equal to rL;

[0111] Step I: Similarly, when the phone detects that the user is holding the phone with the right hand, the alignment APP will automatically adjust the coordinate deviation (rR, θR, φR) to the current radiation direction (r4, θ4, ) to compensate, the Star APP will guide the user to (r4+rR, θ4+θR, ) alignment, so the real direction guided by the mobile phone alignment APP will be (r4+rR, θ4+θR, ), is the actual radiation direction of the right hand.

[0112] Step J: At the same time as step I, the transmitter will adjust the transmit power and increase the transmit power by rR, and implement closed-loop detection of the transmit power through the FBRX path to ensure that the current transmit power increment is equal to rR;

[0113] Step K: Since different users holding mobile phones may have different degrees of signal attenuation, if the target increased power rL / rR exceeds the maximum transmit power capability of the mobile phone, the transmitter transmits at the maximum power.

[0114] It should be noted that this example uses the FBRX circuit to test VSWR to detect the hand holding posture (the attenuation of the signal by the hand can be directly tested under the previous OTA / left hand holding / right hand holding conditions. Here, there is no need to process the signal size, only compensate a fixed value). The user's holding state can also be sensed by measuring the frequency shift caused by the hand holding to the antenna, because the human hand is a conductor. When it touches the antenna radiator, the resonant frequency of the antenna will shift. The cheapness of this resonant frequency can correspond to the position of the hand holding.

[0115] In order to know whether the mobile phone is held in the left hand or the right hand, based on the above Figure 7 , which can be achieved as follows:

[0116] Step 1: The FBRX link can perform frequency sweep operation, and its operating range can cover, for example, 600 MHz to 6 GHz. The FBRX link measures S11 in the entire range of 600 MHz to 6 GHz by scanning.

[0117] Step 2: In the initialization state, the FBRX link scans the free space state respectively, and two S11 vs frequency (Freq) curves can be obtained respectively. That is:

[0118] a) Left antenna S11a in free space

[0119] b) Right antenna S11b in free space

[0120] And record the frequency corresponding to the maximum S11_Max value (absolute value) of S11a and S11b. In this way, the corresponding resonant frequency points of the two antennas can be obtained, namely Freq(R) and Freq(L).

[0121] Fig.11 An optional S11 parameter and frequency curve diagram provided in an embodiment of the present application, wherein the solid line is the S11 parameter curve in free space, and the dotted line is the S11 parameter curve in a hand-held state. It can be seen that the holding state causes an offset in the frequency corresponding to the maximum value of the S11 parameter.

[0122] Step 3: During actual user use, when the alignment APP starts, the FBRX link starts to scan the S11 of the left and right antennas and records the frequency corresponding to the corresponding S11_Max. If the frequency of the left or right side deviates (exceeds the set threshold), it is determined that the user's left antenna or right antenna is currently held, and then the compensation mechanism of the relevant alignment angle parameters is started to complete the alignment operation.

[0123] Among them, the advantage of doing this is that FBRX has full-band scanning, so even if different people hold the antenna with different hands, the frequency deviation caused by it is inconsistent, the mobile phone can still recognize it.

[0124] In this example, the existing cellular communication circuit (including radio frequency circuit and antenna) on the mobile phone is used to detect the user's holding method of the mobile phone (to identify whether the user is holding the mobile phone with the left hand or the right hand). The satellite alignment APP directly calls different parameters to compensate for the differences in the maximum radiation direction and radiation energy of the satellite communication antenna caused by the human hand holding, thereby compensating for the influence of the human hand on the antenna radiation waveform, ensuring that the user can achieve accurate satellite alignment operation (so that the maximum radiation direction of the mobile phone points to the satellite) without feeling anything, and get a better experience.

[0125] It can be seen that the mobile phone automatically compensates for the influence of human hands on the satellite communication antenna without the user noticing, and realizes accurate satellite operation and power adjustment. In addition, the existing antenna and RF circuit of the mobile phone are used without adding additional hardware costs.

[0126] An embodiment of the present application provides a satellite communication method, which is applied to an electronic device, including: determining a holding state of the electronic device, determining a compensation parameter corresponding to the holding state, and using the compensation parameter corresponding to the holding state to compensate for the satellite alignment parameter of the current radiation direction in the holding state to obtain the satellite alignment parameter corresponding to the holding state, wherein the satellite alignment parameter corresponding to the holding state is used for the satellite communication antenna in the electronic device to dock with the satellite, so that the electronic device performs satellite communication through the satellite; that is, in the embodiment of the present application, the holding state of the electronic device is first determined, and then the satellite alignment parameter corresponding to the holding state is determined, and finally the compensation parameter corresponding to the holding state is used to compensate for the satellite alignment parameter of the current radiation direction in the holding state to obtain the satellite alignment parameter corresponding to the holding state, so that the holding state of the electronic device and the compensation parameter are matched one by one, so that when the electronic device is held, the compensation parameter of the holding state can be used to compensate for the satellite alignment parameter corresponding to the holding state, thereby optimizing the satellite alignment parameter of the current radiation direction, and based on the compensated satellite alignment parameter, that is, the satellite alignment parameter corresponding to the holding state, the satellite communication antenna of the electronic device is docked with the satellite, and satellite communication is performed through the satellite communication antenna, thereby improving the communication quality of the electronic device performing satellite communication.
