[0031] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the description of the present application, the meaning of "several" is at least one, such as one, two, etc., unless otherwise clearly and specifically defined.

[0033] With the rapid development of network construction technology and wireless communication technology, the ground network can currently provide good network coverage for most areas, so that most areas can enjoy network resources. However, for sparsely populated areas such as non-land areas, remote mountainous areas and polar areas, the ground network cannot provide good network coverage. Therefore, in this case, satellite communication can generally be used to provide good network coverage for the above-mentioned blind spots (i.e. sparsely populated areas such as non-land areas, remote mountainous areas and polar areas).

[0034] Satellite communication technology can include a communication method that transmits and receives information through artificial satellites. Satellite communication technology can use the high-altitude orbit of communication satellites as a medium to send information to the ground or other locations using high-frequency radio waves, and then the receiver receives and decodes the information, thereby achieving long-distance communication. In general, satellite communication technology can be applied to the fields of television broadcasting, telemedicine, aerospace, logistics and transportation, and scientific exploration.

[0035] In some embodiments, a satellite communication system may include a space segment, a ground segment, and a user segment, wherein the space segment may include a communication satellite; the ground segment may include a gateway, a ground transmission network, and a core network, etc.; the user segment may include various user terminals, such as routers, terminal devices, or computers, etc. Figure 1 The network topology of the terminal device satellite communication system of the embodiment of the present application is shown, and the terminal device satellite communication system may include: terminal device (device), base station (Base station), gateway, 5G core network (5G Core Network) and communication satellite. Among them, the terminal device proposed in the embodiment of the present application includes but is not limited to computers, intelligent voice interaction devices, smart home appliances, vehicle terminals, game consoles, e-book readers, multimedia playback devices, wearable devices and other electronic devices.

[0036] In some embodiments, the communication satellite is hundreds or tens of thousands of kilometers above the earth. Because of this, the extremely long distance between the communication satellite and the earth will cause a large attenuation of the communication signal transmitted from the communication satellite to the earth. In this case, only by aligning the maximum radiation direction of the terminal device with the satellite can the terminal device receive a stronger communication signal as much as possible, thereby improving the quality of satellite communication as much as possible. Therefore, based on the above content, it is particularly important in the field of satellite communication to align the maximum radiation direction of the terminal device with the communication satellite so that the terminal device can obtain a stronger communication signal.

[0037] In addition, the radiation pattern of the terminal device is usually not a completely regular spherical radiation pattern, and the radiation intensity in each radiation direction in the radiation pattern of the terminal device is different. Figure 2 is a schematic diagram of a radiation pattern of a terminal device according to an embodiment of the present application. The radiation pattern can be divided into multiple small areas. Figure 2 In the example shown, the radiation intensity of area 2 is stronger than that of area 1. Of course, it should be noted that for ease of description, Figure 2 Only the radiation intensity of area 1 and area 2 in the antenna radiation pattern is shown, and the radiation intensity of other areas in the antenna radiation pattern is not shown.

[0038] The radiation intensity of each radiation direction in the radiation pattern of the terminal device is different. Therefore, when the maximum radiation direction of the terminal device is aimed at the communication satellite, the signal strength of the signal transmitted by the terminal device when it reaches the satellite is relatively large.

[0039] Therefore, based on the above content, in order to obtain high-quality communication effects, it is usually necessary to align the maximum radiation direction of the terminal device with the satellite. Only then can the signal emitted by the terminal device have a greater signal strength when it reaches the satellite.

[0040] Generally, the antenna direction of the terminal device can be adjusted by pointing to the satellite (i.e., the process of adjusting the attitude, orientation, and direction of the terminal device), so as to align the maximum radiation direction of the terminal device with the satellite.

[0041] At present, there is a method for adjusting the antenna direction of the terminal device by using the satellite alignment method, so as to align the maximum radiation direction of the terminal device with the satellite, which may include the following steps:

[0042] Step 1: obtain the radiation pattern of the terminal device through Over-the-Air Technology (OTA) testing; and determine the maximum radiation direction of the terminal device through the radiation pattern of the terminal device.

[0043] Step 2: Determine the spatial position of the target communication satellite through the pre-downloaded ephemeris information of the communication satellite; wherein the ephemeris information of the communication satellite may include parameters used to describe the satellite orbit, and the embodiment of the present application can determine the spatial position of the communication satellite based on the parameters describing the satellite orbit.

[0044] Step 3: Use the built-in sensors of the terminal device (such as the Global Navigation Satellite System (GNSS), compass, gyroscope and acceleration sensor (acceleration transduce)) to determine the position, orientation, tilt angle and movement direction of the terminal device, which can be used to describe the spatial position of the terminal device.

[0045] Step 4: The sensor transmits the perceived parameters to the central processing unit (CPU), and the CPU transmits the relevant information (such as the maximum radiation direction of the terminal device, the spatial position of the target communication satellite, and the information describing the spatial position of the terminal device) to the application (APP) used to guide the user to perform the satellite pointing operation. After that, the user interface (UI) on the APP can guide the user to perform the satellite pointing operation (i.e., the process of adjusting the attitude, orientation and direction of the terminal setting line) based on the information transmitted by the CPU, and then point the maximum radiation direction of the terminal device to the target communication satellite to complete the satellite pointing operation and obtain high-quality communication effects.

[0046] In addition, in some embodiments, the radio frequency system of the satellite communication terminal in the implementation of the present application can adopt the following Figure 3 The system block diagram shown performs radio frequency (RF) operations. Figure 3 is a block diagram of a radio frequency system of a satellite communication terminal according to an embodiment of the present application, such as Figure 3 As shown, the radio frequency system of the satellite communication terminal may include a sensor module, a transceiver (Transceiver) 300, a power amplifier (PA, Power Amplifier) ​​301, a feedback receiver (FBRX, feedback receiver) low noise amplifier (LNA, Low Noise Amplifier) ​​302, a receiving path (RX, receiver) low noise amplifier 303, a transceiver switch 304, a directional coupler 305 and a central processing unit (CPU, Central Processing Unit) 306. Among them, the transceiver 300 can be used to output control signals and low-power transmission signals, and demodulate RX signals; the central processing unit 306 can be used to output trigger (Trigger) signals. In addition, the radio frequency system of the satellite communication terminal proposed in the embodiment of the present application may not include the FRBX low noise amplifier.

[0047] It should be noted that the above method of determining the maximum radiation direction of the terminal device (i.e., obtaining the radiation pattern of the terminal device through OTA testing, and then obtaining the maximum radiation direction of the terminal device through the radiation pattern of the terminal device) only considers the radiation pattern of the terminal device in the free space state; wherein, the free space state may include an ideal reference state. Normally, there is no gravitational field and electromagnetic field in the free space state.

[0048] However, if the maximum radiation direction of the terminal device is determined only based on the radiation pattern of the terminal device in the free space state, without considering the influence of the holding state of the terminal device on the radiation pattern, the determined maximum radiation direction of the terminal device will be different from the actual maximum radiation direction of the terminal device to a certain extent, which will lead to the communication effect between the terminal device and the communication satellite not reaching the optimal state. The reason for the above problem is generally that when the terminal device is in the holding state, after the satellite alignment operation is performed on the terminal device, the direction of the terminal device pointing to the target communication satellite is different from the actual maximum radiation direction of the terminal device, which is not the optimal direction.

[0049] Therefore, based on the above content, an embodiment of the present application proposes a method for determining the maximum radiation direction of a terminal device. This method can reduce the impact on the maximum radiation direction caused by the terminal device being in a holding state to a certain extent, facilitate the satellite operation of the terminal device, and thus improve the communication effect between the terminal device and the satellite.

[0050] Figure 4 The method for determining the maximum radiation direction of a terminal device according to an embodiment of the present application is a flow chart, including:

[0051] S410, detecting the maximum radiation direction of the terminal device, and determining the holding state of the terminal device;

[0052] S420: Adjust the maximum radiation direction of the terminal device according to the holding state of the terminal device.

[0053] The holding state of the terminal device includes a left-hand holding state or a right-hand holding state.

[0054] The embodiment of the present application adjusts the maximum radiation direction of the detected terminal device by determining the holding state of the terminal device, which can reduce to a certain extent the impact of the user's hand holding the mobile phone on the radiation field pattern during use, thereby improving the communication effect of the terminal device.

[0055] In some implementations, the angle difference between the maximum radiation direction of the terminal device in a holding state and the maximum radiation direction of the terminal device in a free space state may be predetermined and saved. The holding state includes a left-hand holding state or a right-hand holding state, and accordingly, the angle difference between the maximum radiation direction of the terminal device in a left-hand holding state and the maximum radiation direction of the terminal device in a free space state, and the angle difference between the maximum radiation direction of the terminal device in a right-hand holding state and the maximum radiation direction of the terminal device in a free space state may be predetermined and saved.

[0056] In this way, in the process of determining the maximum radiation direction of the terminal device, the maximum radiation direction of the terminal device is first detected and the holding state is determined, and then according to the holding state, the angle difference between the pre-saved maximum radiation direction of the terminal device in the holding state and the maximum radiation direction of the terminal device in the free space state is found, and the angle difference is used to adjust the maximum radiation direction of the terminal device.

[0057] For example, if it is determined that the holding state of the terminal device is left-hand holding, the angle difference between the maximum radiation direction of the terminal device in the left-hand holding state and the maximum radiation direction of the terminal device in the free space state is found, and the detected maximum radiation direction of the terminal device is adjusted using the angle difference. If it is determined that the holding state of the terminal device is right-hand holding, the angle difference between the maximum radiation direction of the terminal device in the right-hand holding state and the maximum radiation direction of the terminal device in the free space state that is pre-saved is found, and the detected maximum radiation direction of the terminal device is adjusted using the angle difference.

[0058] In some embodiments, a method of detecting an angle difference may include:

[0059] Detecting a first radiation pattern of the terminal device in a free space state and a second radiation pattern of the terminal device in a held state;

[0060] The first radiation pattern and the second radiation pattern are used to determine the angular difference between the maximum radiation direction of the terminal device in a held state and the maximum radiation direction of the terminal device in a free space state.

[0061] The second radiation pattern may include the radiation pattern of the terminal device in the left hand holding state, or the radiation pattern of the terminal device in the right hand holding state. Accordingly, two angle differences are detected and saved, namely, the angle difference between the maximum radiation direction of the terminal device in the left hand holding state and the maximum radiation direction of the terminal device in the free space state, and the angle difference between the maximum radiation direction of the terminal device in the right hand holding state and the maximum radiation direction of the terminal device in the free space state.

[0062] The following first introduces a specific method for detecting the angular difference between the maximum radiation direction of the terminal device in a holding state and the maximum radiation direction of the terminal device in a free space state.

[0063] The radiation pattern of the terminal device is different in the free space state, left-hand holding state and right-hand holding state. Figure 5A The radiation field patterns in free space state, left hand holding state, and right hand holding state are shown.

[0064] The process of determining the angle difference may include the following steps:

[0065] Step 1: Detect the radiation field patterns in free space, left hand holding state, and right hand holding state respectively. Figure 5A shown.

[0066] Step 2: Define a three-dimensional spherical coordinate system, such as Figure 5B As shown, the three-dimensional spherical coordinate system may include an x-axis, a y-axis, and a z-axis. In the embodiment of the present application, the three-dimensional spherical coordinate system (Spherical coordinate system) may be represents the position of any point in the three-dimensional spherical coordinate system, where r can be used to represent the effective isotropic radiated power (EIRP) of any point in the three-dimensional spherical coordinate system, and θ can be used to represent the elevation angle of any point in the three-dimensional spherical coordinate system; It can be used to represent the azimuth of any point in the three-dimensional spherical coordinate system. According to the detection result in step 1, the maximum power point in each state can be obtained.

[0067] Step 3: Use the maximum power point in each state to determine the angle difference. Figure 5C As shown, the maximum power point in free space is recorded as

[0068] The maximum power point in the left hand holding state is recorded as

[0069] The maximum power point in the right hand holding state is recorded as

[0070] Using the maximum power points in the above states, the angle difference between the maximum radiation direction of the terminal device in the left hand holding state and the maximum radiation direction in the free space state can be calculated, which is recorded as Among them, θ L =θ 2 -θ 1 ,

[0071] Similarly, the angular difference between the maximum radiation direction of the terminal device in the right-hand holding state and the maximum radiation direction in the free space state can be calculated and recorded as Among them, θ R =θ 3 -θ 1 ,

[0072] Since the present application is used to adjust the direction of the terminal device during the satellite alignment process, there is no need to worry about the impact of holding on the radiation power. Therefore, for simplicity, the above calculation of the angle difference does not consider the difference in maximum radiation power under different states, but is simply recorded as 0.

[0073] After the angle difference is determined, the angle difference can be stored, for example and The angle difference is saved in the memory so that the actual maximum radiation direction of the terminal device can be determined by using the angle difference in the subsequent satellite alignment process.

[0074] For example, after determining and saving the angle difference, the above step S410 is performed to detect the maximum radiation direction of the terminal device and determine the holding state of the terminal device. For example, the detected maximum radiation direction is recorded as The specific detection method will not be described in detail here.

[0075] There are at least two ways to determine the grip state:

[0076] Method 1: Grip Sensor detection method.

[0077] In some implementations, determining the holding state of the terminal device includes: sensing the holding state of the terminal device using a holding sensor.

[0078] For example, Figure 6 is a schematic diagram of the location of the Grip Sensor on a terminal device according to an embodiment of the present application, such as Figure 6 As shown, the embodiment of the present application can determine the holding state of the terminal device through the Grip Sensor on the terminal device. Specifically, the embodiment of the present application can place the Grip Sensor in the lower left direction of the terminal device. When the user holds the terminal device with his left hand, the detection of the terminal device being held in the left hand can be realized, that is, it can be detected that the user is holding the terminal device with his left hand at this time. Similarly, if the Grip Sensor is placed in the lower right direction of the terminal device, the detection of the terminal device being held in the right hand can be realized, that is, when the user holds the terminal device with his right hand, the Grip Sensor can detect that the user is holding the terminal device with his right hand at this time.

[0079] Alternatively, the embodiment of the present application may further place two Grip sensors in the lower left direction and the lower right direction of the terminal device, respectively, to achieve the purpose of detecting that the user is holding the terminal device with his left hand and / or the user is holding the terminal device with his right hand, that is, it can be detected that the user is holding the terminal device with his left hand at this time and / or detect that the user is holding the terminal device with his right hand at this time.

[0080] Method 2: Determine the holding state of the terminal device based on the probability of terminal screen coverage.

[0081] Generally, the screen of an existing terminal device may include a capacitive touch screen. Therefore, if a user operates the capacitive touch screen of the terminal device by holding the device with his left hand, the user's finger may cover the lower left part of the terminal device screen; or, if a user operates the capacitive touch screen of the terminal device by holding the device with his right hand, the user's finger may cover the lower right part of the terminal device screen. In other words, when a user operates the terminal device by holding the device, at least one area of ​​the terminal device screen (such as the lower left part of the terminal device screen and / or the lower right part of the terminal device screen) is usually covered.

[0082] Therefore, based on the above content, the embodiment of the present application can predict the holding state of the terminal device by the probability that the lower left part or the lower right part of the terminal device screen is covered by the user's finger.

[0083] Specifically, determining the holding state of the terminal device includes:

[0084] In a first time period, counting the probability that at least one area of ​​the terminal device screen is covered, and determining the user's holding habit according to the probability;

[0085] According to the holding habit, the holding state of the terminal device is determined.

[0086] For example, the embodiment of the present application may use any application program to respectively count the probability that at least one area of ​​the terminal device screen is covered when the user uses the terminal device in the [tL, t] time period. For example, the probability that the lower left part of the terminal device screen and / or the lower right part of the terminal device screen is covered when the user uses the terminal device in the [tL, t] time period may be respectively counted. Afterwards, the embodiment of the present application may determine the holding habits of the user when using the terminal device based on the probability that at least one area of ​​the terminal device screen is covered in the [tL, t] time period, such as whether the user is more inclined to hold the terminal device with the left hand or the user is more inclined to hold the terminal device with the right hand, and determine the holding state of the terminal device based on the holding habits.

[0087] For example, the embodiment of the present application can use any application program to respectively count the probability of the lower left part of the terminal device screen being covered and the probability of the lower right part of the terminal device screen being covered in the [tL, t] time period. If in the [tL, t] time period, the probability of the lower left part of the terminal device screen being covered is 20%, and the probability of the lower right part of the terminal device screen being covered is 80%, then the user's holding habit of using the terminal device is right-handed, that is, the user is more inclined to the right-handed holding state, and then the holding state of the terminal device can be determined as the right-handed holding state. That is to say, in this embodiment, statistical data can be used to estimate the holding state of the terminal device when performing a satellite alignment operation; if it is determined according to the statistical data that the user's holding habit is left-handed holding, then the holding state of the terminal device when performing a satellite alignment operation is also left-handed holding by default; conversely, if it is determined according to the statistical data that the user's holding habit is right-handed holding, then the holding state of the terminal device when performing a satellite alignment operation is also right-handed holding by default.

[0088] After detecting the maximum radiation direction of the terminal device (denoted as The maximum radiation direction can be considered as the maximum radiation direction in the free space state), and after determining the holding state of the terminal device, the detected maximum radiation direction can be adjusted by using the pre-stored angle difference between the maximum radiation direction in different holding states and the free space state.

[0089] For example, if the terminal device is held in the left hand, the angle difference between the maximum radiation direction of the terminal device in the left hand holding state and the maximum radiation direction in the free space state (i.e., the angle difference between the maximum radiation direction of the terminal device in the left hand holding state and the free space state) can be used. ), adjust or compensate the detected maximum radiation state, and obtain the maximum radiation direction after adjustment or compensation:

[0090] If the terminal device is held in the right hand, the angle difference between the maximum radiation direction of the terminal device in the right hand holding state and the maximum radiation direction in the free space state (i.e., the angle difference between the maximum radiation direction of the terminal device in the right hand holding state and the free space state) can be used. ), adjust or compensate the detected maximum radiation state, and obtain the maximum radiation direction after adjustment or compensation:

[0091] The embodiment of the present application pre-detects and saves the angular difference between the maximum radiation direction of the terminal device in a holding state and the maximum radiation direction of the terminal device in a free space state. When satellite alignment operation is required, the angle difference can be used to adjust or compensate for the maximum radiation direction of the terminal device, thereby compensating for the influence of human hand holding on the satellite communication antenna and achieving accurate satellite alignment operation.
