Description

Technical Field

[0001] 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

[0002] Satellite communication has a long communication distance and wide coverage. It is not restricted by external factors such as specific regions, weather, terrain, power supply and other ground infrastructure. It can ensure communication quality in more complex application scenarios such as emergency communication, tourism and leisure, Internet of Things, disaster prevention and relief, and environmental protection. It has advantages that cannot be replaced by cellular communication. With the development of communication technology, satellite communication has gradually been applied to terminal devices represented by smartphones as a necessary function, making the functions of terminal devices more and more powerful to meet people's growing needs.

[0003] Traditional satellite communication equipment uses high-performance antennas to provide better transceiver performance. However, when applied to terminal devices such as smartphones, it is difficult to set up antennas specifically for satellite communications due to the limited space of the terminal devices. Therefore, the same antenna is often reused with cellular mobile communications.

[0004] However, when two communication systems reuse the same antenna, the performance of one of the communication systems may be affected, affecting 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. Summary of the invention

[0005] 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.

[0006] In a first aspect, a satellite communication control method is provided, which is applied to a satellite transceiver circuit, the satellite transceiver circuit comprising: a satellite processor, and the method comprising: 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 responds to the satellite communication switching instruction, outputs a satellite control signal, the satellite control signal being used to control the tuning state of an antenna tuning module when switching to satellite communication.

[0007] The above-mentioned satellite communication control method outputs a satellite control signal to instruct the antenna tuning module to switch to the tuning state matched by the satellite communication when the terminal device switches to the satellite communication state, thereby ensuring that when the same antenna and the control interface of the antenna tuning module are reused with other communication systems, the antenna performance of other communication systems is not affected, and the satellite communication can also work in the scenario where the antenna reaches the tuning state, thereby ensuring the antenna performance during satellite communication and the communication quality of 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.

[0008] 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.

[0009] Optionally, the antenna controller can be external to the satellite transceiver circuit and used in conjunction with the satellite transceiver circuit; it can also be integrated in the satellite transceiver circuit, which is not limited in the embodiments of the present application. When the antenna controller is integrated in the satellite transceiver circuit, the integration of the module can be improved. The antenna controller is in a wake-up state through the wake-up level to realize the tuning function of satellite communication and ensure the communication quality of satellite communication.

[0010] 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 then 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 switching to satellite communication.

[0011] 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.

[0012] In one possible implementation, the satellite antenna tuning parameters also include satellite antenna transmit tuning parameters, and the method also includes: when the transmit time slot of the satellite communication arrives, the satellite processor outputs a transmit high level, and the transmit high level is used to characterize that the satellite communication is switched to the transmit state; the antenna controller responds to the transmit high level and outputs the transmit tuning parameters of the transmitting satellite antenna, and the satellite antenna transmit tuning parameters are used to instruct the antenna tuning module to switch to the tuning state under the transmit state of the satellite communication.

[0013] When 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 communications.

[0014] 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 satellite communication to be shut down.

[0015] The satellite processor may shut down satellite communications to save power in response to receiving the satellite communications shut down instruction.

[0016] 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.

[0017] The satellite processor can also stop satellite communication when receiving a satellite communication shutdown instruction. Optionally, the satellite communication shutdown instruction can be an instruction generated by the user manually shutting down the satellite communication, or an instruction automatically generated when the cellular mobile communication resumes the communication state, or an instruction generated by the terminal device when the screen is off or locked. For example, when the user uses the terminal device to make a satellite call, a pull-down operation can be performed at the top of the screen of the terminal device, the pull-down bar can be opened, and the switch control of the satellite communication can be clicked in the pull-down bar to generate a satellite communication shutdown instruction to turn off the satellite communication function. The user manually shuts down the satellite communication in accordance with the user's wishes, and the operation method is flexible; it can also be that the terminal device detects that the signal strength of the cellular mobile communication is restored and can be used normally, and then automatically generates a satellite communication shutdown instruction to shut down the satellite communication, and then can switch to the communication state of the cellular mobile communication; it can also be that the user has finished using the satellite communication, and the terminal device automatically or under the user's operation becomes a screen-off or lock screen state. At this time, the terminal device believes that the user no longer needs to use the terminal device for satellite communication, and then it 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.

[0018] 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 to output 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 characterize 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.

[0019] By building a conversion module into the satellite processor, the GPIO level can be converted into a MIPI signal, which can be used to transmit satellite antenna tuning parameters, thereby tuning the antenna tuning module. The satellite transceiver circuit can achieve impedance tuning of the antenna tuning module without using an antenna controller. While ensuring the performance of the satellite communication antenna, it also simplifies the circuit structure and circuit connection method, making layout and wiring easier.

[0020] In one possible implementation, the satellite antenna tuning parameters include satellite antenna reception tuning parameters, and the satellite antenna reception tuning parameters are used to instruct the antenna tuning module to switch to a tuning state under a 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 outputs 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 outputs them to the antenna tuning module.

[0021] 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 switch more timely.

[0022] In one possible implementation, the satellite antenna tuning parameters also include satellite antenna transmit tuning parameters, and the satellite antenna transmit tuning parameters are used to indicate that the antenna tuning module switches to the tuning state under the transmit state of satellite communication. The method also includes: when the transmit time slot of satellite communication arrives, the satellite processor outputs a transmit high level, and the transmit high level is used to characterize that the satellite communication is switched to the transmit state; the satellite processor uses a conversion module to convert the transmit high level into a satellite antenna transmit tuning parameter, and outputs it to the antenna tuning module.

[0023] 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 satellite antenna reception tuning parameters, and then use MIPI signals 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 it is just switched, and has good reception performance. When the transmission time slot arrives, the satellite processor will also generate a high transmission level, and then input the high transmission level into the conversion module for conversion, generate satellite antenna transmission tuning parameters, and then use MIPI signals 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.

[0024] In a possible implementation manner, the method further includes: the satellite processor stops outputting the satellite antenna tuning parameters in response to the satellite communication shutdown instruction.

[0159] As we all know, satellite communication has a long communication distance and a wide coverage. It is not restricted by external factors such as specific regions, weather, terrain, power supply and other ground infrastructure. It can ensure the communication quality in more complex application scenarios such as emergency communication, tourism and leisure, Internet of Things, disaster prevention and relief, environmental protection, etc. Therefore, it has advantages that cannot be replaced by cellular communication. With the development of communication technology, satellite communication has gradually been applied to terminal devices represented by smartphones as a necessary function, making the functions of terminal devices more and more powerful to meet people's growing needs.

[0160] Traditional satellite communication equipment uses high-performance antennas to provide better transceiver performance. However, when used in terminal devices such as smartphones, it is difficult to set up antennas specifically for satellite communications due to the limited space of the terminal devices. Therefore, the same antenna is often reused with cellular mobile communications. However, when two communication systems reuse the same antenna, it is often difficult to be compatible with the two communication states due to the impedance matching in the same state, which will affect the performance of one of the communication systems and affect the user experience.

[0161] 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, thereby ensuring that when the same antenna and the control interface of the antenna tuning module are reused with other communication systems, the antenna performance of other communication systems is not affected, and the satellite communication can also work in the antenna matching state, thereby ensuring the antenna performance during satellite communication and the communication quality of 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.

[0162] For ease of understanding, the following embodiments of the present application will be described in detail with Figure 1 and Figure 2 Taking the terminal device of the shown structure as an example, the satellite communication control method and satellite transceiver circuit provided in the embodiments of the present application are specifically explained in combination with the accompanying drawings and application scenarios.

[0163] Figure 3 is a flow chart of a satellite communication control method provided in an embodiment of the present application. The method can be applied to Figure 4 The satellite transceiver circuit shown in FIG. 1 includes a satellite processor, which can be called a satellite communication central processor (CP). Figure 3 As shown, the satellite communication control method includes:

[0164] S301. A satellite processor receives a satellite communication switching instruction, where the satellite communication switching instruction is used to instruct switching to satellite communication.

[0165] It should be noted that the satellite communication switching instruction can be an instruction generated based on the user's operation of turning on satellite communication. For example, when a user uses a terminal device to make a call, it is found that the signal of the cellular mobile communication here is very weak and cannot be used normally. Then, a pull-down operation can be performed at the top of the screen of the terminal device to open the pull-down bar, and the switch control of the satellite communication in the pull-down bar is clicked to generate a satellite communication switching instruction to turn on the satellite communication function. Optionally, the satellite communication switching instruction can also be that when the user is using the terminal device, the terminal device detects that the signal of the cellular mobile communication is very weak and cannot be connected to the Internet normally, and automatically switches to satellite communication. When the terminal device switches to the satellite communication state, a satellite communication switching instruction needs to be sent to the satellite processor to instruct the satellite processor to enter the working state to realize satellite communication.

[0166] S302: The satellite processor outputs a satellite control signal in response to the satellite communication switching instruction, where the satellite control signal is used to control the antenna tuning module to switch to a tuning state when satellite communication is performed.

[0167] When the satellite processor receives the satellite communication switching instruction, it can respond, that is, output a satellite control signal. The satellite control signal can indicate that it is necessary to enter the satellite communication state at this time. At this time, the antenna tuning module can be adjusted to the tuning state matched during satellite communication under the instruction of the satellite control signal, so that the antenna is in a resonant state during satellite communication, so that the antenna performance can ensure the communication quality of satellite communication. The antenna performance described in the embodiment of the present application may include but is not limited to indicators such as antenna gain, antenna directivity, or isolation between other antennas.

[0168] Optionally, when the terminal device enters satellite communication, other communication systems may enter a dormant state.

[0169] In order to clearly explain 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 A schematic diagram of a T-shaped impedance matching network with adjustable impedance is shown. Among them, the specific values ​​of inductors L1 and L2, and capacitors C1 can be adjusted under the action of impedance tuning parameters. As the values ​​of inductors and capacitors change, the impedance of the impedance matching network will change to adapt to different impedance requirements. The common use of antenna tuning modules is as follows: during the debugging process of the antenna of the terminal device, different impedance matching 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 set of different antenna tuning parameters, and different groups of antenna tuning parameters and corresponding impedance matching forms and corresponding frequency bands or communication standards are established. Correspondence. When the terminal device works 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, so that the antenna is in a tuning state to ensure communication quality.

[0170] 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, thereby ensuring that when the same antenna and the control interface of the antenna tuning module are reused with other communication systems, the antenna performance of other communication systems is not affected, and the satellite communication can also work in the scenario where the antenna reaches the tuning state, thereby ensuring the antenna performance during satellite communication and the communication quality of 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.

[0171] Optionally, the above Figure 3 and Figure 4 In the embodiment shown, 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; it can also be integrated in the satellite transceiver circuit, which is not limited in the 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; it can also be integrated in the satellite transceiver circuit, which is not limited in the embodiment of the present application.

[0172] Figure 6 The schematic diagram of the circuit structure is a satellite transceiver circuit that also integrates an antenna controller, wherein the antenna controller is connected to a satellite processor. Figure 6 The satellite communication system in the system is a software system running on a system-on-a-Chip (SOC) to support satellite communication. Among them, the satellite RF module is used to process the RF signal during satellite communication (also known as the satellite transceiver signal). The satellite RF module is connected and used in conjunction with the satellite processor to realize the processing of the satellite transceiver signal. Figure 6 In the figure, the antenna and the antenna tuning module are shown as a whole. Optionally, the antenna tuning module and the antenna can also be set separately to facilitate flexible design and layout, as long as the antenna tuning module is close to the antenna, it is convenient for antenna debugging. Usually, when the cellular mobile communication signal is poor and normal communication cannot be achieved, the antenna controller often enters a dormant state. When the satellite communication starts working, the antenna controller can be woken up first. In some embodiments, the satellite control signal can output a high level, which can be called a wake-up level (wake up), which is used to wake up the antenna controller. Optionally, the wake-up level can also be a low level, so when the antenna controller does not need to be woken up, it maintains a high level, and when it needs to be woken up, it switches to a low level to wake up the antenna controller; optionally, when the wake-up level is a low level, 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 be in the wake-up state from the dormant state. When the antenna receives the wake-up level output by the satellite processor, it can switch from the dormant state to the wake-up state; optionally, after the satellite processor is woken up, the satellite antenna tuning parameters can be directly output 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), which can receive MIPI signals. The satellite antenna tuning parameters are the antenna tuning parameters corresponding to satellite communication, which 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 use requirements during satellite communication.

[0173] 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 to the embodiments of the present application.

[0174] In some embodiments, satellite communication signals can be switched with other communication signals through switches to implement a multiplexing antenna technology solution. Other communication signals can be cellular mobile communication signals, short-range wireless communication (such as Wifi, Bluetooth, etc.) signals, etc. For details, please refer to Figure 7 As shown, Figure 7 In the figure, different communication channels are switched by a first switch, a satellite radio frequency module is integrated in a satellite transceiver circuit, and the first switch is a single-pole double-throw switch. Figure 7 The antenna tuning parameters corresponding to other communication systems in are called other antenna tuning parameters, and 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 other communication systems. Figure 7 As shown, 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 RF 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 send and receive satellite communication signals, including satellite transmission signals and satellite reception signals. When pins 2-3 of the first switch are turned on, the first switch can select other communication channels, and the antenna can be used to send and receive signals from other communication systems.

[0175] In some embodiments, since the frequencies of satellite communication transceiver signals are relatively close, satellite communication transceiver signals are often transmitted in separate channels. For example, satellite transmission signals go through a transmission path, and satellite reception signals go through a reception path. The reception path and the transmission path can be switched by a second switch. Figure 8 In the example, the satellite communication transceiver channel is switched by the second switch, the satellite transceiver circuit integrates the satellite radio frequency module and the second switch, and the second switch is a single-pole double-throw switch. Figure 8As shown, 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, which is used to receive the satellite transmit signal output by the satellite RF module, and connect the satellite transmit signal to the antenna through the common end of the second switch (such as pin 3) for transmission. Another discrete end of the second switch (such as the second discrete end, pin 2) receives the satellite receive 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 transmit 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 receive path of the satellite communication, so that the satellite processor and the satellite RF module work together to process the satellite receive signal.

[0176] Optionally, Figure 8 The embodiment shown can also be used with Figure 7 In combination with the embodiment shown in the figure, the signal channels of different communication systems are selected by the first switch, and the channels for receiving and transmitting signals during satellite communication are selected by the second switch. For details, please refer to Fig. 9 shown.

[0177] It should be noted that the above Figure 7-Figure 9 The first switch and / or the second switch in the embodiment may also adopt other multi-port switches, such as double-pole double-throw, double-pole triple-throw, single-pole three-throw and single-pole four-throw switches, and may also share multi-port switches with other channels. For example, the first switch may 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 satisfied, and the embodiments of the present application do not limit this. Figure 7-Figure 9 The second switch is shown as being integrated in a satellite transceiver circuit. In fact, the second switch can also be independent of the satellite transceiver circuit and used as an external component in combination with the satellite transceiver circuit. The first switch can also be integrated in the satellite transceiver circuit, and this is not limited to the embodiments of the present application.

[0178] In some embodiments, Figure 8 and Fig. 9 Taking the satellite transceiver circuit shown as an example, when the communication state is switched to satellite communication, the satellite communication receiving state can be entered by default. At this time, the satellite antenna tuning parameters include the satellite antenna receiving tuning parameters, and the antenna controller directly outputs the satellite antenna receiving tuning parameters by default after switching from the sleep state to the awake state in response to the wake-up level. The antenna tuning module switches to the tuning state under the satellite communication receiving state under the instruction of the satellite antenna receiving tuning parameters to ensure the receiving performance of the satellite communication.

[0179] When the transmission time slot of satellite communication arrives, the satellite processor can output a high level of transmission to indicate that the satellite communication switches from the receiving state to the transmitting state. In response to the high level of transmission, the antenna controller outputs the transmission tuning parameters of the transmitting satellite antenna. Under the instruction of the satellite antenna transmission tuning parameters, the antenna tuning module switches to the tuning state under the transmitting state of the satellite communication to ensure the transmission performance of the satellite communication. Optionally, the level indicating that the satellite communication switches to the transmitting state can also be a low level; optionally, when the level indicating that the satellite communication switches to the transmitting state is a low level, an external inverter can be used to convert the level indicating that the satellite communication switches to the transmitting state to a high level. The embodiment of the present application does not limit the level indicating that the satellite communication switches to the transmitting state, as long as it can trigger the antenna controller to switch from the tuning state of the receiving state to the tuning state of the transmitting state, the embodiment of the present application does not limit this. That is, as long as the levels of switching the transmitting state and switching the receiving state are one high and one low, the transceiver switching can be realized, and it is not limited to which state is a high level or a low level. Take the example of the satellite processor outputting a high level of transmission in the transmitting state. When the receiving time slot arrives and the satellite communication needs to switch to the receiving state, the satellite processor can switch from the high level of transmission to the low level of reception, so that the satellite communication switches to the receiving state. Here, the high level of transmission and the low level of reception are collectively referred to as the switching level (switch), that is, the satellite processor can realize the transmission and reception switching by switching the high and low levels of the output.

[0180] It should be noted that in the embodiment of the present application, the transmission time slot of the satellite transmission refers to the time period when the satellite processor processes the satellite transmission signal, and the reception time slot refers to the time period when the satellite processor processes the satellite reception signal. It is not used to distinguish the specific working time periods of the satellite transmission signal and the satellite reception signal, nor is it used to limit the satellite communication to a frequency division or time division communication mode. At this time, there can be two paths, the first path and the second path, between the satellite processor and the antenna controller, one for transmitting the wake-up signal, and the other for outputting the switching level to the antenna controller, such as outputting a high level for transmission or a low level for reception. For details, please refer to Fig.10 shown.

[0181] Optionally, the antenna controller can be used not only to output corresponding antenna tuning parameters to other communication systems and satellite communication systems, but also to output antenna tuning parameters required by other communication systems and more antennas (such as antenna 1 and antenna 2), and other communication systems can also include various components set on the signal channel, such as switches, etc., which can be seen in Fig.11 Examples in . Fig.11 The satellite transceiver circuit in the embodiment includes a satellite processor, a satellite radio frequency module and a second switch, and Fig.11In the figure, other communication systems include 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 paths in each communication system can also switch the transceiver state through the switches in their respective paths, which will not be repeated here.

[0182] On the basis of the above embodiment, the satellite processor can also stop satellite communication when receiving the satellite communication shutdown instruction. Optionally, the satellite communication shutdown instruction can be an instruction generated by the user manually shutting down the satellite communication, or an instruction automatically generated when the cellular mobile communication resumes the communication state, or an instruction generated by the terminal device when the screen is off or locked. For example, when the user uses the terminal device to make a satellite call, a pull-down operation can be performed at the top of the screen of the terminal device, the pull-down bar can be opened, and the switch control of the satellite communication can be clicked in the pull-down bar to generate a satellite communication shutdown instruction to turn off the satellite communication function. The user manually shuts down the satellite communication in accordance with the user's wishes, and the operation method is flexible; it can also be that the terminal device detects that the signal strength of the cellular mobile communication is restored and can be used normally, and then automatically generates a satellite communication shutdown instruction to shut down the satellite communication, and then can switch to the communication state of the cellular mobile communication; it can also be that the user has finished using the satellite communication, and the terminal device automatically or under the user's operation becomes a screen-off or lock screen state. At this time, the terminal device believes that the user no longer needs to use the terminal device for satellite communication, and then it 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.

[0183] In some embodiments, after receiving the satellite communication shutdown instruction, the satellite processor responds by outputting a shutdown low level to the antenna controller, which can instruct the antenna controller to switch from the awake state to the sleep state and no longer output the satellite antenna tuning parameters, thereby saving power consumption. Optionally, the antenna controller can then switch to the corresponding tuning state under the instruction of the antenna tuning parameters output by other communication systems.

[0184] In order to clearly describe the working sequence of satellite communication, Fig.12 A complete timing diagram is used to describe in detail the timing of satellite communication startup and shutdown. Specifically, it may include:

[0185] S1201. The satellite communication system sends a satellite communication switching instruction to the satellite processor.

[0186] 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 (power up) instructing the satellite processor to power on is issued. This instruction can be called a satellite communication switching instruction.

[0187] S1202: The satellite processor raises the level of the output port of the wake-up level in response to the satellite communication switching instruction.

[0188] S1203: The satellite processor outputs a wake-up level to the antenna controller through the first path.

[0189] 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.

[0190] S1204: The antenna controller switches from the sleep state to the wake-up state in response to the wake-up level, and outputs the satellite antenna reception tuning parameters by default.

[0191] At this time, the satellite processor outputs a default low level to the antenna controller through the second path.

[0192] 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.

[0193] S1206. The satellite processor outputs a transmit high level to the antenna controller through the second path.

[0194] The transmission high level may be a level output by a GPIO port.

[0195] S1207: In response to the high level transmission, the antenna controller switches from outputting satellite antenna reception tuning parameters to outputting satellite antenna transmission tuning parameters.

[0196] Afterwards, the antenna controller can perform transmission and reception switching under the control of the switching level (periodically changing transmission high level and reception low level) output by the satellite processor to adapt the tuning state of the transmission and reception state of the satellite communication.

[0197] When no satellite communication service is being carried out, for example, no satellite call is being carried out, the receiving state of satellite communication can also be maintained, that is, the downlink synchronization state can be maintained. Specifically, the switching level can be made to maintain the receiving low level output, so that the antenna controller can maintain the state of outputting the satellite antenna receiving tuning parameters to ensure the receiving performance of satellite communication.

[0198] S1208. The satellite communication system sends a satellite communication shutdown instruction to the satellite processor.

[0199] The satellite communication system can also be referred to as a satellite protocol stack on a terminal device, and can generate a satellite communication shutdown instruction based on a system event. For example, when satellite communication is not needed, the satellite communication system sends a satellite communication shutdown instruction to the satellite processor. The satellite communication shutdown instruction can be based on a user's operation of shutting down satellite communication, a cellular mobile communication system resuming communication, or a system event such as screen extinguishing or screen locking, and sends a command (power off) to instruct the satellite processor to power off.

[0200] 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.

[0201] 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.

[0202] Fig.12 The implementation principle and technical effects of the embodiments can be found in the description of the aforementioned embodiments and will not be repeated here.

[0203] 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, usually the GPIO level output by the satellite processor 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 may be provided in the satellite processor. The conversion module is capable of converting the GPIO level into a MIPI signal, and directly outputting a MIPI signal to instruct the antenna tuning module to perform impedance tuning.

[0204] The circuit structure of setting the conversion module in the satellite processor can be seen in Fig.13 When receiving the 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 satellite antenna tuning parameters, and then transmit them using MIPI signals. Specifically, it can be output to the antenna tuning module through the path connected between the satellite processor and the antenna tuning module, so that the satellite communication has good communication performance.

[0205] In the above embodiment, by building a conversion module into the satellite processor, the GPIO level of the antenna tuning module can be converted into the form of a MIPI signal, which can be used to transmit the satellite antenna tuning parameters, thereby realizing the tuning of the antenna tuning module. The satellite transceiver circuit can realize the impedance tuning of the antenna tuning module without using an antenna controller, and simplifies the circuit structure and circuit connection method while ensuring the performance of the satellite communication antenna, which is convenient for layout and wiring.

[0206] Optionally, Fig.13 In the example, the satellite transceiver circuit includes a satellite processor, and the satellite radio frequency module and the first switch are both externally placed in the satellite transceiver circuit. Optionally, the satellite radio frequency module and the first switch can also be integrated with the satellite processor or separately in the satellite transceiver circuit.

[0207] Optionally, in the above Fig.13 Based on the embodiment shown, the satellite communication receiving and transmitting signals can also be transmitted through separate channels. For the circuit structure of the satellite communication receiving and transmitting signals through separate channels, please refer to the aforementioned Figure 8 and Fig. 9 The examples are not repeated here.

[0208] Based on the above embodiments, a conversion module can be provided in a satellite processor to avoid using an antenna controller during satellite communication. The specific implementation principles and technical effects will not be described in detail here.

[0209] In one possible implementation, combining Fig. 9 and Fig.13 In the embodiment, the circuit of the built-in conversion module in the satellite processor can also refer to Fig.14 shown. Fig.14 Take the example of a satellite transceiver circuit including a processor, a satellite RF module and a second switch. Specifically, the satellite transmit signal goes through the transmit path, and the satellite receive signal goes through the receive path. The receive path and the transmit path can be switched by the second switch. When receiving the 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 receive tuning parameters, and then use the MIPI form of 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, and has good receiving performance. When the transmission time slot arrives, the satellite processor will also generate a high level of transmission, and then input the high level of transmission into the conversion module for conversion, generate the satellite antenna transmission tuning parameters, and then use the MIPI form of 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.
