Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a satellite communication control method, a satellite transceiver circuit and related products. Background Art

[0003] Satellite communications offer long range and wide coverage, unrestricted by external factors such as specific regions, weather, terrain, power supply, and other ground infrastructure. They guarantee communication quality in complex applications such as emergency communications, tourism and leisure, the Internet of Things, disaster prevention and relief, and environmental protection, offering advantages unmatched by cellular communications. With the advancement of communications technology, satellite communications have become increasingly essential for devices like smartphones, making them increasingly powerful and meeting people's growing needs.

[0004] Traditional satellite communication equipment uses high-performance antennas to provide excellent transceiver performance. However, when used in terminal devices such as smartphones, due to the limited space on the terminal devices, it is difficult to set up a dedicated antenna for satellite communication. Therefore, the same antenna is often reused for cellular mobile communication.

[0005] However, when two communication systems reuse the same antenna, the performance of one of the communication systems may be affected, which in turn affects the user experience, because the impedance matching state of the same state is difficult to be compatible with the working states of the two communication systems.

[0006] Summary of the Invention

[0007] The present application provides a satellite communication control method, a satellite transceiver circuit, a satellite processor, a radio frequency front-end module and an electronic device, which can improve the communication quality of satellite communication.

[0008] In a first aspect, a satellite communication control method is provided, which is applied to a satellite transceiver circuit, the satellite transceiver circuit including: a satellite processor, and the method including: the satellite processor receiving a satellite communication switching instruction, the satellite communication switching instruction being used to indicate switching to satellite communication; the satellite processor outputting a satellite control signal in response to the satellite communication switching instruction, the satellite control signal being used to control the tuning state of the antenna tuning module when switching to satellite communication.

[0009] The satellite communication control method outputs a satellite control signal to instruct the antenna tuning module to switch to a tuning state suitable for satellite communication when the terminal device switches to satellite communication mode. This ensures that, when the same antenna and antenna tuning module control interface are reused with other communication systems, the antenna performance of the other communication system is not affected while satellite communication can still operate when the antenna reaches a tuned state, thus ensuring antenna performance and communication quality during satellite communication. Furthermore, the reuse of the same antenna and control port for controlling the antenna tuning module by two communication systems can also save costs.

[0010] In one possible implementation, the satellite transceiver circuit also includes: an antenna controller, the satellite control signal includes a wake-up level, and the satellite processor outputs a satellite control signal in response to a satellite communication switching instruction, including: the antenna controller receives the wake-up level output by the satellite processor; the antenna controller switches from a sleep state to a wake-up state in response to the wake-up level, and outputs satellite antenna tuning parameters, and the satellite antenna tuning parameters are used to indicate the tuning state of the antenna tuning module when switching to satellite communication.

[0011] Optionally, the antenna controller can be external to the satellite transceiver circuit and used in conjunction with it; it can also be integrated within the satellite transceiver circuit, though this is not a limitation in the present embodiment. Integrating the antenna controller within the satellite transceiver circuit improves module integration. By activating the wake-up level, the antenna controller is kept awake to achieve satellite communication tuning, ensuring high-quality satellite communication.

[0012] In one possible implementation, the satellite antenna tuning parameters include satellite antenna reception tuning parameters, and the antenna controller switches from a sleep state to a wake-up state in response to a wake-up level and outputs the satellite antenna tuning parameters, including: the antenna controller switches from a sleep state to a wake-up state in response to the wake-up level, and outputs the satellite antenna reception tuning parameters, and the satellite antenna reception tuning parameters are used to indicate the tuning state of the antenna tuning module in the reception state when it switches to satellite communication.

[0013] When the antenna controller is awakened, it can directly default to the receiving state and output the satellite antenna receiving tuning parameters to achieve downlink synchronization of satellite communication, ensuring the receiving performance of satellite communication. There is no need to wait for instructions from other signals to enter the receiving state, and satellite communication switching can be more timely.

[0014] In one possible implementation, the satellite antenna tuning parameters also include satellite antenna transmission tuning parameters, and the method also includes: when the transmission time slot of satellite communication arrives, the satellite processor outputs a transmission high level, and the transmission high level is used to indicate that the satellite communication is switched to the transmission state; the antenna controller responds to the transmission high level and outputs the transmitting satellite antenna transmission tuning parameters, and the satellite antenna transmission tuning parameters are used to instruct the antenna tuning module to switch to the tuning state under the transmission state of satellite communication.

[0015] In the transmitting state, the satellite processor also outputs a transmitting high level to the antenna controller, so that the antenna controller can respond to the transmitting high level to control the antenna controller to output the satellite antenna transmitting tuning parameters to ensure the transmitting performance of satellite communication.

[0016] In a possible implementation manner, the method further includes: the satellite processor receiving a satellite communication shutdown instruction, where the satellite communication shutdown instruction is used to instruct the satellite communication to be shut down.

[0017] The satellite processor may shut down satellite communications to conserve power in response to receiving the satellite communications shut down instruction.

[0018] In a possible implementation, the method further includes: the satellite processor outputting a shutdown low level to the antenna controller in response to the satellite communication shutdown instruction; and the antenna controller switching from the awake state to the sleep state in response to the shutdown low level.

[0019] The satellite processor can also stop satellite communications upon receiving a satellite communications shutdown command. Optionally, the satellite communications shutdown command can be generated by a user manually shutting down satellite communications, automatically generated when cellular mobile communications resume communication, or generated when the terminal device's screen is off or locked. For example, after a user completes a satellite call using a terminal device, they can pull down from the top of the terminal device's screen to open a pull-down bar and click the satellite communications switch in the pull-down bar to generate a satellite communications shutdown command, turning off the satellite communications function. Manually shutting down satellite communications by the user meets the user's wishes and offers flexibility. Alternatively, the terminal device can automatically generate a satellite communications shutdown command upon detecting that the cellular mobile communications signal strength has recovered and can be used normally, thereby shutting down satellite communications and then switching back to cellular mobile communications. Alternatively, the user can complete satellite communications and the terminal device automatically or at the user's request turns the screen off or locked. At this point, the terminal device deems that the user no longer needs to use the terminal device for satellite communications and can automatically generate a satellite communications shutdown command to save power. The terminal device automatically generates a satellite communication shutdown instruction, which can be shut down in time without manual operation by the user, which is more convenient and can save power.

[0020] In one possible implementation, the satellite control signal includes a wake-up level, a conversion module is set in the satellite processor, and the satellite processor responds to the satellite communication switching instruction and outputs the satellite control signal, including: the satellite processor generates a wake-up level in response to the satellite communication switching instruction, and the wake-up level is used to represent entering the satellite communication state; the satellite processor uses the conversion module to convert the wake-up level into a satellite antenna tuning parameter, and outputs it to the antenna tuning module.

[0021] By integrating a conversion module into the satellite processor, GPIO levels can be converted into MIPI signals, which can be used to transmit satellite antenna tuning parameters, thereby tuning the antenna tuning module. This satellite transceiver circuit can achieve impedance tuning of the antenna tuning module without the need for an antenna controller. While ensuring the performance of the satellite communication antenna, it also simplifies the circuit structure and circuit connection method, facilitating layout and wiring.

[0022] In one possible implementation, the satellite antenna tuning parameters include satellite antenna reception tuning parameters, which are used to instruct the antenna tuning module to switch to a tuning state under the reception state of satellite communication. The satellite processor uses a conversion module to convert the wake-up level into the satellite antenna tuning parameters and output them to the antenna tuning module, including: the satellite processor uses a conversion module to convert the wake-up level into the satellite antenna reception tuning parameters and output them to the antenna tuning module.

[0023] When switching to satellite communication, the satellite processor can directly default to the receiving state, and use the conversion module to convert the generated wake-up level into the satellite antenna receiving tuning parameters to achieve downlink synchronization of satellite communication, ensure the receiving performance of satellite communication, and no longer need to wait for instructions from other signals to enter the receiving state, which can also make the satellite communication switching more timely.

[0024] In one possible implementation, the satellite antenna tuning parameters also include satellite antenna transmission tuning parameters, which are used to indicate that the antenna tuning module switches to the tuning state of the satellite communication transmission state. The method also includes: when the transmission time slot of the satellite communication arrives, the satellite processor outputs a transmission high level, and the transmission high level is used to indicate that the satellite communication is switched to the transmission state; the satellite processor uses a conversion module to convert the transmission high level into a satellite antenna transmission tuning parameter, and outputs it to the antenna tuning module.

[0025] When receiving a satellite communication switching instruction, the satellite processor will still generate a wake-up level, and then input the wake-up level into the conversion module for conversion, generate the satellite antenna reception tuning parameters, and then use the MIPI format signal for transmission. Specifically, it can be output to the antenna tuning module through the connection between the satellite processor and the antenna tuning module, so that the satellite communication maintains downlink synchronization when just switching, with good reception performance. When the transmission time slot arrives, the satellite processor will also generate a transmission high level, and then input the transmission high level into the conversion module for conversion, generate the satellite antenna transmission tuning parameters, and then use the MIPI format signal for transmission. Specifically, it can be output to the antenna tuning module through the connection path between the satellite processor and the antenna tuning module, so that the satellite communication has good communication performance in the transmission state.

[0026] In a possible implementation manner, the method further includes: the satellite processor stopping outputting the satellite antenna tuning parameters in response to a satellite communication shutdown instruction.

[0029] The satellite processor can also stop satellite communications upon receiving a satellite communications shutdown command. Optionally, the satellite communications shutdown command can be generated by a user manually shutting down satellite communications, automatically generated when cellular mobile communications resume communication, or generated when the terminal device's screen is off or locked. For example, after a user completes a satellite call using a terminal device, they can pull down from the top of the terminal device's screen to open a pull-down bar and click the satellite communications switch in the pull-down bar to generate a satellite communications shutdown command, turning off the satellite communications function.

Alternatively, the terminal device can automatically generate a satellite communications shutdown command upon detecting that the cellular mobile communications signal strength has recovered and can be used normally, thereby shutting down satellite communications and then switching back to cellular mobile communications. Alternatively, the user can complete satellite communications and the terminal device automatically or at the user's request turns the screen off or locked. At this point, the terminal device deems that the user no longer needs to use the terminal device for satellite communications and can automatically generate a satellite communications shutdown command to save power.

[0031] In the aforementioned satellite transceiver circuit, the satellite processor can, when switched to satellite communication mode, output a satellite control signal to instruct the antenna tuning module to switch to a tuning state suitable for satellite communication. This ensures that, when the same antenna and antenna tuning module control interface are reused with other communication systems, the antenna performance of the other communication system is not affected while satellite communication can still operate when the antenna reaches a tuned state, thus ensuring antenna performance and communication quality during satellite communication.

In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships can exist, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0085] In the following, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated.

[0087] For example, FIG1 is a schematic diagram of the structure of a terminal device 100 provided in an embodiment of the present application. The terminal device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a button 190, a motor 191, an indicator 192, a camera 193, a display 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, an air pressure sensor 180C, a magnetic sensor 180D, an acceleration sensor 180E, a distance sensor 180F, a proximity light sensor 180G, a fingerprint sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.

[0088] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the terminal device 100. In other embodiments of the present application, the terminal device 100 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently.

[0091] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly access the memory.

[0142] Figure 2 is a software structure diagram of the terminal device 100 according to an embodiment of the present application. The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, namely, the application layer, the application framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer, from top to bottom. The application layer may include a series of application packages.

[0145] As shown in FIG2 , the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

[0146] The window manager is used to manage window programs. The window manager can obtain the display size, determine whether there is a status bar, lock the screen, take screenshots, etc.

[0147] Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0148] The view system includes visual controls, such as those for displaying text and images. The view system is used to build applications. A display interface can consist of one or more views. For example, a display interface containing a text notification icon might include a view for displaying text and a view for displaying images.

[0149] The phone manager is used to provide communication functions of the terminal device 100, such as management of call status (including answering, hanging up, etc.).

[0150] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0151] The Notification Manager allows applications to display notifications in the status bar. These messages can be displayed briefly and then disappear automatically, without requiring user interaction. For example, the Notification Manager can be used to notify users of completed downloads and message reminders. The Notification Manager can also display notifications in the top status bar of the system as icons or scrolling text, such as notifications from background applications, or as dialog windows on the screen. Examples include displaying text messages in the status bar, emitting alert sounds, vibrating the device, or flashing indicator lights.

[0152] The Android runtime includes the core library and the virtual machine. The Android runtime is responsible for scheduling and management of the Android system.

[0153] The core library consists of two parts: one is the function that needs to be called by the Java language, and the other is the Android core library.

[0154] The application layer and application framework layer run in a virtual machine. The virtual machine executes Java files in the application layer and application framework layer as binary files. The virtual machine manages object lifecycles, stack management, thread management, security and exception management, and garbage collection.

[0155] The system library can include multiple functional modules, such as a surface manager, media libraries, a 3D graphics processing library (such as OpenGL ES), and a 2D graphics engine (such as SGL).

[0156] The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

[0159] A 2D graphics engine is a drawing engine for 2D drawings.

[0160] The kernel layer is the layer between hardware and software. The kernel layer includes at least display driver, camera driver, audio driver, and sensor driver.

[0161] As we all know, satellite communications offer long range and wide coverage, unrestricted by external factors such as specific regions, weather, terrain, power supply, and other ground infrastructure. They can guarantee communication quality in complex application scenarios such as emergency communications, tourism and leisure, the Internet of Things, disaster prevention and relief, and environmental protection, offering advantages that cannot be replaced by cellular communications. With the advancement of communications technology, satellite communications have gradually been applied to terminal devices, such as smartphones, as essential features, making these devices increasingly powerful and meeting people's growing needs.

[0162] Traditional satellite communication equipment uses high-performance antennas to provide excellent transmit and receive performance. However, when used in terminal devices such as smartphones, the limited space makes it difficult to install dedicated antennas for satellite communications. Therefore, the same antenna is often reused for cellular mobile communications. However, when two communication systems share the same antenna, impedance matching often makes it difficult to achieve compatibility between the two communication modes. This can affect the performance of one communication system and the user experience.

[0163] In the satellite communication control method provided in the embodiment of the present application, when the terminal device switches to the satellite communication state, a satellite control signal is output to instruct the antenna tuning module to switch to the tuning state matched by the satellite communication. This ensures that when the same antenna and antenna tuning module control interface are reused with other communication systems, the antenna performance of the other communication system is not affected, and the satellite communication can also operate in the antenna matching state, thereby ensuring the antenna performance during satellite communication and the communication quality of the satellite communication. At the same time, the two communication systems reuse the same antenna and the control port for controlling the antenna tuning module, which can also save costs.

[0164] For ease of understanding, the following embodiments of this application will take a terminal device having the structure shown in Figures 1 and 2 as an example, and combine the accompanying drawings and application scenarios to specifically explain the satellite communication control method and satellite transceiver circuit provided in the embodiments of this application.

[0165] FIG3 is a flow chart of a satellite communication control method provided by an embodiment of the present application. The method can be applied to the satellite transceiver circuit shown in FIG4 . The satellite transceiver circuit includes a satellite processor, which can be called a satellite communication central processor (CP). As shown in FIG3 , the satellite communication control method includes:

[0166] S301: A satellite processor receives a satellite communication switching instruction, where the satellite communication switching instruction is used to instruct switching to satellite communication.

[0167] It should be noted that the satellite communication switching instruction can be an instruction generated based on the user's operation to turn on satellite communication. For example, when a user uses a terminal device to make a call and finds that the cellular mobile communication signal is very weak and cannot be used normally, the user can perform a pull-down operation at the top of the terminal device screen to open the pull-down bar and click the satellite communication switch control in the pull-down bar to generate a satellite communication switching instruction and turn on the satellite communication function. Optionally, the satellite communication switching instruction can also be when the user is using the terminal device and the terminal device detects that the cellular mobile communication signal is very weak and cannot connect to the network normally, and automatically switches to satellite communication. When the terminal device switches to the satellite communication state, it is necessary to send a satellite communication switching instruction to the satellite processor to instruct the satellite processor to enter the working state to achieve satellite communication.

[0168] S302: The satellite processor outputs a satellite control signal in response to the satellite communication switching instruction. The satellite control signal is used to control the antenna tuning module to switch to a tuning state for satellite communication.

[0169] When the satellite processor receives a satellite communication switching instruction, it can respond by outputting a satellite control signal. This satellite control signal can indicate that the satellite communication state needs to be entered at this time. At this time, the antenna tuning module can be instructed by the satellite control signal to adjust to the tuning state that matches the satellite communication state, thereby placing the antenna in a resonant state during satellite communication, so that the antenna performance can ensure the communication quality of the satellite communication. The antenna performance referred to in the embodiments of the present application may include but is not limited to indicators such as antenna gain, antenna directivity, or isolation from other antennas.

[0170] Optionally, when the terminal device enters satellite communication, other communication systems may enter a dormant state.

[0171] In order to clearly illustrate the implementation principle of the embodiment of the present application, the antenna tuning module is introduced here. The antenna tuning module can be regarded as an impedance matching network with adjustable impedance. The form of the impedance matching network is not limited and can be L-type, T-type, π-type or a combination of these types. Figure 5 shows a schematic diagram of a T-shaped impedance matching network with adjustable impedance. Among them, the specific values ​​of the inductors L1 and L2, and the capacitor C1 can be adjusted under the action of the impedance tuning parameters. As the values ​​of the inductors and capacitors change, the impedance of the impedance matching network will change to adapt to different impedance requirements. The common way to use the antenna tuning module is: during the debugging process, the antenna of the terminal device can be debugged for different frequency bands or different communication standards to adapt the antenna to achieve a tuning state. Each form of impedance matching corresponds to a different set of antenna tuning parameters, and a correspondence is established between different groups of antenna tuning parameters and corresponding impedance matching forms and corresponding frequency bands or communication standards. When the terminal device operates in a certain communication standard or frequency band, the above correspondence can be queried to find the antenna tuning parameters that match the current frequency band or communication standard, and then the impedance of the antenna tuning module is adjusted based on this antenna tuning parameter to put the antenna in a tuned state to ensure communication quality.

[0172] In the embodiments of the present application, when the terminal device switches to satellite communication mode, a satellite control signal is output to instruct the antenna tuning module to switch to a tuning state that matches satellite communication. This ensures that, when the same antenna and antenna tuning module control interface are reused with other communication systems, the antenna performance of the other communication system is not affected, while satellite communication can also operate in scenarios where the antenna reaches a tuned state, thereby ensuring antenna performance during satellite communication and ensuring the communication quality of satellite communication. Furthermore, the reuse of the same antenna and control port for controlling the antenna tuning module by two communication systems can also save costs.

[0173] Optionally, in the embodiments shown in Figures 3 and 4 above, the satellite transceiver circuit includes a satellite processor, and the antenna tuning module can be external to the satellite transceiver circuit and used in conjunction with the satellite transceiver circuit; or it can be integrated into the satellite transceiver circuit, which is not limited in this embodiment of the present application. Optionally, the antenna controller can also be external to the satellite transceiver circuit and used in conjunction with the satellite transceiver circuit; or it can be integrated into the satellite transceiver circuit, which is not limited in this embodiment of the present application.

[0174] Figure 6 is a schematic diagram of a circuit structure in which an antenna controller is integrated into the satellite transceiver circuit, wherein the antenna controller is connected to the satellite processor. The satellite communication system in Figure 6 is a software system running on a system-on-a-chip (SOC) to support satellite communications. The satellite RF module is used to process the RF signals (also known as satellite transceiver signals) used during satellite communications. This satellite RF module is connected to and used in conjunction with the satellite processor to process the satellite transceiver signals. Figure 6 shows the antenna and antenna tuning module as a whole. Optionally, the antenna tuning module and antenna can be provided separately to facilitate flexible design and layout. As long as the antenna tuning module is relatively close to the antenna, antenna debugging is convenient. Typically, when the cellular mobile communication signal is poor and normal communication is impossible, the antenna controller often enters a dormant state. When satellite communication begins, the antenna controller can be awakened first. In some embodiments, the satellite control signal can output a high level, which can be called a wake-up level, to awaken the antenna controller. Optionally, the wake-up level can also be a low level, so that it remains at a high level when the antenna controller does not need to be woken up, and switches to a low level to wake up the antenna controller when it needs to be woken up; optionally, when the wake-up level is low, an external inverter can be used to convert the wake-up level to a high level. The embodiment of the present application does not limit the level of the wake-up level, as long as it can trigger the antenna controller to switch from the sleep state to the wake-up state. When the antenna receives the wake-up level output by the satellite processor, it can switch from the sleep state to the wake-up state; optionally, after the satellite processor is woken up, it can directly output the satellite antenna tuning parameters by default. It should be noted that the interface of the antenna tuning module can usually be in the form of a mobile industry processor interface (MIPI) and can receive MIPI signals. The satellite antenna tuning parameters are the antenna tuning parameters corresponding to satellite communication and can be transmitted to the antenna tuning module in the form of MIPI signals. Under the guidance of the satellite antenna tuning parameters, the antenna tuning module can adjust the impedance to the tuning state matched during satellite communication, so that the performance of the antenna meets the usage requirements during satellite communication.

[0175] Optionally, the satellite RF module can be externally placed on the satellite transceiver circuit and used in conjunction with the satellite transceiver circuit; it can also be integrated into the satellite transceiver circuit, which is not limited in the embodiments of the present application.

[0176] In some embodiments, satellite communication signals can be switched with other communication signals through a switch to implement a technical solution for multiplexing antennas. Other communication signals can be signals for cellular mobile communications, short-range wireless communications (such as Wifi, Bluetooth, etc.), etc. For details, please refer to Figure 7, which takes the example of switching different communication channels through a first switch, integrating a satellite radio frequency module in a satellite transceiver circuit, and the first switch being a single-pole double-throw switch. The antenna tuning parameters corresponding to the other communication systems in Figure 7 are called other antenna tuning parameters. The other tuning parameters can be used to instruct the antenna tuning module to tune the antenna to a matching state to ensure the communication quality of the other communication systems. As shown in Figure 7, the common end of the first switch (such as pin 3) can be connected to the antenna, one of the discrete ends of the first switch (such as the first discrete end, pin 1) can be connected to the satellite radio frequency module, and the other discrete end (such as the second discrete end, pin 2) can be connected to other communication channels. When pins 1-3 of the first switch are turned on, the first switch can select the satellite communication channel, and the antenna can be used to transmit and receive satellite communication signals, including satellite transmit signals and satellite receive signals. When pin 2 - 3 of the first switch is turned on, the first switch can select other communication channels, and the antenna can be used to transmit and receive signals of other communication systems.

[0177] In some embodiments, since the frequencies of the satellite communication transceiver signals are relatively close, the satellite communication transceiver signals are often transmitted in separate channels. For example, the satellite transmission signal takes the transmission path, and the satellite reception signal takes the reception path, and the reception path and the transmission path can be switched by a second switch. FIG8 is an example of switching the satellite communication transceiver channel by a second switch, integrating a satellite RF module and a second switch in the satellite transceiver circuit, and the second switch being a single-pole double-throw switch. As shown in FIG8 , one of the discrete ends of the second switch (such as the first discrete end, pin 1) is connected to the transmit output end of the satellite RF module, for receiving the satellite transmission signal output by the satellite RF module, and connecting the satellite transmission signal to the antenna through the common end of the second switch (such as pin 3) for transmission. The other discrete end of the second switch (such as the second discrete end, pin 2) receives the satellite reception signal transmitted by the common end of the second switch, and outputs it to the receive input end of the connected satellite RF module. When pins 1-3 of the second switch are turned on, the second switch can select the transmitting path of the satellite communication, so that the satellite processor and the satellite RF module work together to transmit the satellite transmit signal; when pins 2-3 of the second switch are turned on, the second switch can select the receiving path of the satellite communication, so that the satellite processor and the satellite RF module work together to process the satellite receive signal.

[0178] Optionally, the embodiment shown in FIG8 can also be combined with the embodiment shown in FIG7 , by selecting the signal channels of different communication systems through the first switch, and selecting the channels for transmitting and receiving signals during satellite communication through the second switch, as shown in FIG9 .

[0179] It should be noted that the first switch and / or the second switch in Figures 7-9 above can also adopt other multi-port switches, such as double-pole double-throw, double-pole triple-throw, single-pole triple-throw and single-pole four-throw switches, and can also share multi-port switches with other channels. For example, the first switch can also add other ports to be compatible with communication channels of other frequency bands of the cellular mobile communication system. As long as the channel switching state described in the above embodiment can be met, the embodiments of the present application are not limited to this. The second switch in Figures 7-9 above is shown as an example of being integrated into a satellite transceiver circuit. In fact, the second switch can also be independent of the satellite transceiver circuit as an external component and used in conjunction with the satellite transceiver circuit; the first switch can also be integrated into the satellite transceiver circuit, and the embodiments of the present application are not limited to this.

[0180] In some embodiments, using the satellite transceiver circuit shown in Figures 8 and 9 as an example, when the communication state is switched to satellite communication, the satellite communication reception state can be entered by default. In this case, the satellite antenna tuning parameters include satellite antenna reception tuning parameters. In response to the wake-up level, the antenna controller directly outputs the satellite antenna reception tuning parameters by default after switching from the sleep state to the awake state. The antenna tuning module, under the direction of the satellite antenna reception tuning parameters, switches to the tuning state for the satellite communication reception state, ensuring satellite communication reception performance.

[0181] When the satellite communication transmission time slot arrives, the satellite processor can output a high transmit level to indicate that the satellite communication has switched from a receive state to a transmit state. In response to the high transmit level, the antenna controller outputs the transmit tuning parameters for the transmitting satellite antenna. In response to the high transmit level, the antenna tuning module switches to the tuned state for the transmit state of the satellite communication, ensuring the transmission performance of the satellite communication. Optionally, the level indicating that the satellite communication has switched to the transmit state can also be a low level. Optionally, when the level indicating that the satellite communication has switched to the transmit state is low, an external inverter can be used to convert the level indicating that the satellite communication has switched to the transmit state to a high level. The embodiments of the present application do not limit the level indicating that the satellite communication has switched to the transmit state; as long as it is a level that can trigger the antenna controller to switch from the receive state to the transmit state, the embodiments of the present application are not limited to this. That is, as long as the levels for switching between the transmit state and the receive state are high and low, the transmit-receive switch can be achieved, and there is no restriction on which state is high or low. For example, when a satellite processor outputs a high level in the transmit state, when a receive time slot arrives and satellite communication needs to switch to the receive state, the satellite processor can switch from the transmit high level to the receive low level, switching the satellite communication to the receive state. Here, the transmit high level and the receive low level are collectively referred to as the switch level. That is, the satellite processor can switch between transmitting and receiving by switching the output high and low levels.

[0182] It should be noted that in the embodiments of the present application, the transmit timeslot of satellite transmission refers to the period during which the satellite processor processes satellite transmit signals, and the receive timeslot refers to the period during which the satellite processor processes satellite receive signals. These timeslots are not intended to distinguish between specific operating periods for satellite transmit and receive signals, nor are they intended to limit satellite communication to frequency division or time division communication. In this case, two pathways, a first pathway and a second pathway, can be provided between the satellite processor and the antenna controller: one for transmitting a wake-up signal and the other for outputting a switching level to the antenna controller, such as outputting a high level for transmit or a low level for receive. See FIG10 for details.

[0183] Optionally, the above-mentioned antenna controller can not only be used to output corresponding antenna tuning parameters to other communication systems and satellite communication systems, but also output antenna tuning parameters required by other more communication systems and more antennas (such as antenna 1 and antenna 2), and other communication systems may also include various components set on the signal channel, such as switches, etc., as shown in the example in Figure 11. The satellite transceiver circuit in Figure 11 is exemplified by including a satellite processor, a satellite RF module and a second switch, and Figure 11 takes other communication systems including communication system 1, communication system 2 and communication system 3, and the satellite communication system and communication system 3 reuse antenna 3 as an example. Each communication system has a corresponding radio frequency integrated circuit (RFIC) 1, radio frequency chip 2 and radio frequency chip 3. The transceiver path in each communication system can also switch the transceiver status through the switches in their respective paths, which will not be repeated here.

[0184] Based on the above embodiment, the satellite processor can also stop satellite communication upon receiving a satellite communication shutdown instruction. Optionally, the satellite communication shutdown instruction can be a command generated by the user manually shutting down satellite communication, a command automatically generated when the cellular mobile communication resumes communication, or a command generated when the terminal device turns off the screen or locks the screen. For example, after a user completes a satellite call using the terminal device, they can pull down from the top of the terminal device screen to open the pull-down bar and click the satellite communication switch control in the pull-down bar to generate a satellite communication shutdown instruction and turn off the satellite communication function. Manually shutting down satellite communication by the user meets the user's wishes and is flexible. Alternatively, the terminal device can automatically generate a satellite communication shutdown instruction to shut down satellite communication upon detecting that the cellular mobile communication signal strength has recovered and can be used normally, thereby switching back to the cellular mobile communication communication state. Alternatively, the user can finish using satellite communication and the terminal device automatically or at the user's request turns off the screen or locks the screen. At this time, the terminal device determines that the user no longer needs to use the terminal device for satellite communication and can automatically generate a satellite communication shutdown instruction to save power. The terminal device automatically generates a satellite communication shutdown instruction, which can be shut down in time without manual operation by the user, which is more convenient and can save power.

[0185] In some embodiments, upon receiving a satellite communication shutdown instruction, the satellite processor may respond by outputting a low-level shutdown signal to the antenna controller. This low-level shutdown signal may instruct the antenna controller to switch from an awake state to a dormant state and no longer output satellite antenna tuning parameters, thereby saving power. Optionally, the antenna controller may then switch to a corresponding tuning state in response to antenna tuning parameters output by other communication systems.

[0186] In order to clearly describe the working sequence of satellite communication, Figure 12 uses a complete timing diagram to introduce the timing of satellite communication startup and shutdown in detail. Specifically, it may include:

[0187] S1201. The satellite communication system sends a satellite communication switching instruction to the satellite processor.

[0188] The satellite communication system can also be called the satellite protocol stack on the terminal device, which can generate satellite communication switching instructions based on system events. For example, based on the user's operation of turning on satellite communication, an instruction to power on the satellite processor (power up) is issued. This instruction can be called a satellite communication switching instruction.

[0189] S1202: The satellite processor raises the level of the output port of the wake-up level in response to the satellite communication switching instruction.

[0190] S1203: The satellite processor outputs a wake-up level to the antenna controller through the first path.

[0191] The wake-up level here takes a high level as an example, and the wake-up level is the level output by the GPIO port.

[0192] S1204: The antenna controller switches from the sleep state to the awake state in response to the awakening level, and outputs the satellite antenna reception tuning parameters by default.

[0193] At this time, the satellite processor outputs a default low level to the antenna controller through the second path.

[0194] S1205: When the transmission time slot arrives, the satellite processor pulls up the level of the output port of the switching level and outputs a transmission high level.

[0195] S1206: The satellite processor outputs a transmit high level to the antenna controller through the second path.

[0196] The transmit high level may be a level output by a GPIO port.

[0197] S1207 : In response to the high level transmission, the antenna controller switches from outputting the satellite antenna receiving tuning parameters to outputting the satellite antenna transmitting tuning parameters.

[0198] Afterwards, the antenna controller can perform transceiver switching under the control of the switching level (periodically changing transmission high level and reception low level) output by the satellite processor to adapt to the tuning state of the transceiver state of the satellite communication.

[0199] When satellite communication services are not being conducted, such as when no satellite calls are being made, the satellite communication reception state can be maintained, i.e., the downlink synchronization state can be maintained. Specifically, the switching level can be set to maintain a low-level reception output, and the antenna controller can maintain the state of outputting the satellite antenna reception tuning parameters to ensure satellite communication reception performance.

[0200] S1208. The satellite communication system sends a satellite communication shutdown instruction to the satellite processor.

[0201] The satellite communication system, also known as the satellite protocol stack on a terminal device, can generate a satellite communication shutdown instruction based on system events. For example, when satellite communication is no longer needed, the satellite communication system issues a satellite communication shutdown instruction to the satellite processor. This satellite communication shutdown instruction can be issued based on system events such as a user shutting down satellite communication, the cellular mobile communication system resuming communication, or a screen extinguishing or locking, instructing the satellite processor to power off.

[0202] S1209 : In response to the satellite communication shutdown instruction, the satellite processor pulls down the level of the output port of the wake-up level and outputs a shutdown low level.

[0203] S1210: In response to the shutdown low level, the antenna controller switches from the awake state to the sleep state, and stops outputting the satellite antenna reception tuning parameters and the satellite antenna transmission tuning parameters.

[0204] The implementation principle and technical effects of the embodiment of Figure 12 can be found in the description of the previous embodiments and will not be repeated here.

[0205] Optionally, in the above embodiment, the satellite transceiver circuit may no longer use an antenna controller, that is, the satellite transceiver circuit does not include an antenna controller, or the satellite transceiver circuit is no longer used in conjunction with an antenna controller. Typically, the antenna tuning module can perform impedance tuning under the control of a MIPI signal, but cannot perform tuning in response to the high and low levels output by the GPIO port. Then, the GPIO level output by the satellite processor usually cannot instruct the antenna tuning module to switch the tuning state, resulting in poor antenna performance during satellite communication. In one possible implementation, a conversion module can be set in the satellite processor. The conversion module can convert the GPIO level into a MIPI signal, and directly output the MIPI signal to instruct the antenna tuning module to perform impedance tuning.

[0206] The circuit structure of the conversion module set in the satellite processor can be seen in Figure 13. When receiving a satellite communication switching instruction, the satellite processor will still generate a wake-up level, which is then input into the conversion module for conversion to generate satellite antenna tuning parameters. This is then transmitted using MIPI signals. Specifically, it can be output to the antenna tuning module through the path connecting the satellite processor and the antenna tuning module, ensuring good satellite communication performance.

[0207] In the above embodiment, by integrating a conversion module into the satellite processor, the GPIO level of the antenna tuning module can be converted into a MIPI signal format, which can be used to transmit the satellite antenna tuning parameters, thereby achieving tuning of the antenna tuning module. This satellite transceiver circuit can achieve impedance tuning of the antenna tuning module without the need for an antenna controller. While ensuring the performance of the satellite communication antenna, it also simplifies the circuit structure and circuit connection method, facilitating layout and wiring.

[0208] Optionally, FIG13 illustrates an example in which the satellite transceiver circuit includes a satellite processor, wherein the satellite RF module and the first switch are both externally located in the satellite transceiver circuit. Optionally, the satellite RF module and the first switch may also be integrated into the satellite transceiver circuit together with the satellite processor or separately.

[0209] Alternatively, based on the embodiment shown in FIG13 , the satellite communication transceiver signals may be transmitted in separate channels. The circuit structure for transmitting the satellite communication transceiver signals in separate channels can be found in the examples shown in FIG8 and FIG9 , and will not be described in detail here.

[0210] Based on the above embodiments, the use of an antenna controller during satellite communication can be avoided by setting a conversion module in the satellite processor. The specific implementation principles and technical effects are not described in detail here.

[0211] In one possible implementation, in conjunction with the embodiments of Figures 9 and 13 , a circuit for a built-in conversion module in a satellite processor can also be seen in Figure 14 . Figure 14 illustrates a satellite transceiver circuit including a processor, a satellite RF module, and a second switch. Specifically, satellite transmit signals travel along a transmit path, while satellite receive signals travel along a receive path. The receive and transmit paths can be switched via the second switch. Upon receiving a satellite communication switch command, the satellite processor generates a wake-up level, which is then input into the conversion module for conversion, generating satellite antenna receive tuning parameters. These parameters are then transmitted using a MIPI signal. Specifically, these parameters are output to the antenna tuning module via the connection between the satellite processor and the antenna tuning module, ensuring that satellite communication maintains downlink synchronization upon switching and maintains good reception performance. When a transmit timeslot arrives, the satellite processor generates a transmit high level, which is then input into the conversion module for conversion, generating satellite antenna transmit tuning parameters. These parameters are then transmitted using a MIPI signal. Specifically, these parameters are output to the antenna tuning module via the connection between the satellite processor and the antenna tuning module, ensuring good satellite communication performance during transmission.
