[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the embodiments of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.
[0026] In the following description, reference is made to “some embodiments”, which describe a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.
[0027] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.
[0029] The present application embodiment provides a signal receiving and transmitting method, such as Figure 1A As shown, the method includes:
[0030] Step S110, obtaining a first trigger signal, where the first trigger signal is used to instruct setting a satellite communication mode;
[0031] Here, satellite communication uses satellites as relay stations to establish a connection between electronic devices and satellites. The relay station can transmit the received satellite text messages or voice call information to the satellite communication equipment in the hands of relevant rescue agencies or personnel. That is, in an emergency, electronic devices can send SOS distress messages to the outside world.
[0032] The process by which electronic devices send signals to satellite communications equipment in the hands of rescue agencies or personnel includes:
[0033] Electronic devices send signals to satellites in the sky through their built-in satellite communication modules and antennas. These satellite signals are usually within a specific frequency range to ensure that they can be effectively received by the satellite. Common frequency ranges include the L band, which includes 1.1 GHz to 1.7 GHz. After receiving the satellite signal sent by the electronic device, the satellite performs amplification and frequency conversion on the satellite to improve the transmission quality of the satellite signal and adapt to different communication needs. The processed satellite signal is resent back to the other end of the earth by the satellite, a process called signal relay.
[0034] The signal forwarded by the satellite is received by a ground station or another mobile phone with satellite communication function. The ground station is usually equipped with a large antenna and advanced signal receiving equipment to ensure stable reception of signals from the satellite. The received satellite signal will be demodulated and decoded to restore the original information content. This process can be completed by the signal processing equipment of the ground station. The demodulated signal will be further transmitted to the target device or further transmitted through the ground network. For example, in an emergency, the received satellite text message or voice call information will be transmitted to the satellite communication equipment in the hands of relevant rescue agencies or personnel.
[0035] During implementation, when it is determined that the person holding the electronic device is in an emergency and cannot use cellular network communication, the first trigger signal can be triggered to set the electronic device to satellite communication mode.
[0036] Here, cellular network communication is a technology that uses cellular wireless networking to connect terminals (electronic devices) and network devices through wireless channels, thereby enabling users to communicate with each other during activities. In cellular communication, voice and data are converted into signals suitable for wireless transmission through modulation technology. The base station is responsible for modulating these signals for uplink transmission to the network, and also modulating downlink signals to send to user devices. However, when cellular network communication is not covered by the base station or the base station fails, there is a problem that electronic devices are affected by the base station network and cannot communicate with the outside world. For example, when the user holds an electronic device in a blind spot of the base station network, it is impossible to use the cellular network to communicate with the outside world.
[0037] Step S120, in response to the first trigger signal, enabling the satellite communication mode;
[0038] Electronic devices have built-in satellite communication capabilities, which can enable emergency text messages or voice calls to be sent via satellite when there is no cellular network coverage.
[0039] During implementation, the satellite communication mode is enabled, that is, emergency text messages are sent or voice calls are made via satellite in this satellite communication mode.
[0040] Step S130, communicating with the satellite through a first signal link and communicating with the satellite through a second signal link based on the satellite communication mode;
[0041] At least one of the first signal link and the second signal link belongs to a cellular network signal link.
[0042] Here, the first signal link and the second signal link are signal links capable of independently transmitting and receiving signals, wherein at least one signal link can transmit and receive cellular network signals in cellular network communication.
[0043] During implementation, the signal link for sending and receiving cellular network signals can be set up so that it can send and receive satellite signals in the satellite communication mode, and together with the signal link capable of communicating with the satellite, realize communication with the satellite.
[0044] In some embodiments, the first signal link and the second signal link may both be configured to transmit and receive cellular network signals. In the satellite communication mode, the first signal link and the second signal link may be reconfigured to transmit and receive satellite signals.
[0045] Here, satellite communication can use frequency division multiple access (FDMA) or time division multiple access (TDMA), or other multiple access methods, such as code division multiple access (CDMA). The first signal link and the second signal link can be a signal link supporting frequency division multiple access, a signal link supporting time division multiple access, or a signal link supporting code division multiple access. Among them, time division multiple access technology realizes multiple access communication by dividing time periods. In satellite communication, time is divided into a series of time slots, and each ground station sends or receives signals within a specified time slot. The time division multiple access method has a high spectrum utilization rate. Due to the limitation of spectrum resources of satellite communication, most current electronic devices use time division multiple access for satellite communication.
[0046] In some embodiments, the first signal link may be a link set in the electronic device for transmitting and receiving satellite signals; the second signal link may be a link set in the electronic device for transmitting and receiving cellular network signals. In the satellite communication mode, the second signal link may be set to transmit and receive satellite signals.
[0047] In some embodiments, the electronic device is equipped with multiple signal links, and the enhancement of the satellite signal circuit is not limited to one satellite transmission signal. The power amplifiers in the multiple signal links arranged in the electronic device can be used to amplify the satellite transmission signal, so that multiple signal links can simultaneously amplify the satellite signals to be transmitted.
[0048] In the embodiment of the present application, in the satellite communication mode, at least one signal link belonging to the cellular network signal link can be used to communicate with the satellite. In this way, the signal link for sending and receiving satellite signals can be added to send and receive satellite signals, thereby achieving the purpose of enhancing the sending and receiving of satellite signals, thereby effectively improving the satellite communication performance of the electronic device.
[0049] In some embodiments, in the above step S130, "communicating with the satellite through the first signal link and communicating with the satellite through the second signal link based on the satellite communication mode" can be implemented by the following process:
[0050] A signal switch is switched based on the satellite communication mode so that the first signal link communicates with the satellite and the second signal link communicates with the satellite, wherein the signal switch is arranged between the first signal link and the second signal link.
[0051] Here, a signal switch can be set between the first signal link and the second signal link, and the signal switch can transfer the signal of one of the signal links to another signal link. For example, when the first signal link is a satellite communication link and the second signal link is a cellular network communication link, the signal switch can be used to switch the satellite signal sent by the first signal link to the second signal link. The parameters of the signal switch are set to have the insertion loss as small as possible within the satellite signal operating frequency band. For example, the insertion loss of the signal switch can be set to about 0.3 decibels (Decibel, dB), not exceeding 1dB. In this way, the amplification and transmission of one satellite signal are increased, which can effectively improve the transmission quality and efficiency of the satellite signal.
[0052] Figure 1B A schematic diagram of a signal transceiver circuit provided in an embodiment of the present application, such as Figure 1B As shown, the schematic diagram includes: a first signal link 11 for receiving satellite signals and a second signal link 12 for receiving cellular network signals, a signal switch 13 and a coupler 14, wherein:
[0053] The first signal link 11 includes: a satellite transceiver 111 , a satellite power amplifier 112 and a satellite antenna 113 . The second signal link 12 includes: a cellular network signal transceiver 121 , a cellular network power amplifier 122 and a cellular network antenna 123 .
[0054] The signal switch 13 is a single-pole double-throw switch, and its terminal 131 is connected to the input terminal of the cellular network amplifier 122, its terminal 132 is connected to the output terminal of the cellular network signal transceiver 121, and its terminal 133 is connected to the coupling terminal 143 of the coupler 14.
[0055] Coupler 14 is a three-terminal directional coupler, which is a passive device in microwave technology. It consists of a main line, a sub-line and a coupling structure. The main line is responsible for signal transmission, while the sub-line is used for signal extraction. When the microwave signal is transmitted in the main line, part of the signal energy can be transferred to the sub-line through the coupling structure. By adjusting the design of the coupling structure, the signal strength coupled to the sub-line can be controlled to meet the needs of different application scenarios. End 141 to end 142 of coupler 14 is the main line, which can transmit satellite signals to satellite antenna 113; end 141 to end 143 are coupling ends, which can couple the satellite signal input to end 141 to end 143.
[0056] During the implementation process, when the electronic device is switched to the satellite communication mode, the state of the signal switch 13 can be switched to connect the 133 end with the 131 end, so as to transmit the satellite signal coupled from the coupling end 143 of the coupler 14 to the cellular network power amplifier 122 of the second signal link 12, and then transmit the coupled satellite signal through the cellular network antenna 123.
[0057] In some embodiments, when the electronic device is set to the cellular network communication mode, the state of the signal switch 13 can be switched to connect the terminal 132 with the terminal 131, so that the second signal link 12 can transmit the cellular network signal generated by the cellular network signal transceiver 121 to the cellular network power amplifier 122 of the second signal link 12, and then transmit the cellular network signal through the cellular network antenna 123. Transmission of the cellular network signal using the second signal link 12 is achieved.
[0058] In the embodiment of the present application, based on the switching of the signal switch in the satellite communication mode, the signal switch can be used to couple the satellite signal to the link for transmitting the cellular network signal for transmission. In this way, in the satellite mode, the amplifier and antenna of the cellular network signal link are reused to realize the communication between the first signal link and the satellite and the communication between the second signal link and the satellite, which effectively improves the strength and efficiency of transmitting the satellite signal in the satellite mode.
[0059] In some embodiments, in the above step S130, “communicating with the satellite through the first signal link and communicating with the satellite through the second signal link based on the satellite communication mode”, for example Figure 2 As shown, it can also be achieved by the following steps:
[0060] Step S210: using a coupler to couple the satellite signal modulated by the satellite signal modulator to the second signal link, so as to transmit the satellite signal through the second signal link, wherein the satellite signal modulator is arranged in the first signal link, and is used to provide the first signal link with the satellite signal to be transmitted;
[0061] Here, the satellite signal modulator, also known as the modulation part in the satellite modem, can be used to modulate the input data signal and convert it into a satellite signal suitable for transmission in the satellite communication channel. The modulation process involves a variety of technologies, including frequency modulation (FM), phase modulation (PM) and frequency modulation (FSK).
[0062] In the case where the first signal link is used for satellite communication, a satellite signal modulator may be arranged in the first signal link, such as Figure 1B As shown, the satellite signal debugger can be set in the satellite transceiver 111 of the first signal link 11, and the generated satellite signal is input to the satellite power amplifier 112 and then transmitted through the satellite antenna 113.
[0063] During implementation, the satellite signal modulator can generate a transmittable satellite signal by modulating the data signal. The satellite signal is then transmitted through key components such as a power amplifier and a satellite antenna.
[0064] In satellite communication mode, the satellite signal modulator can generate a satellite signal that can be transmitted by modulating the data signal. The signal coupler can be used to couple part of the signal energy to the link originally used to transmit the cellular network signal, so that the satellite signal can be amplified by the amplifier on the cellular network signal link and then transmitted through the cellular network antenna.
[0065] For example, if Figure 1B As shown, when the satellite signal passes through the coupler 14, part of the signal energy can be coupled to the signal switch 13, and by setting the signal switch 13, the coupled satellite signal is transmitted through the cellular network amplifier 122 and the cellular network antenna 123 set on the second signal link 12.
[0066] Here, the cellular amplifier can be designed to match the satellite transmission frequency band, which can integrate frequency band selection, power requirements, linearity, efficiency, anti-interference ability, etc. Through reasonable design and optimization, it can be ensured that the cellular amplifier has stable performance and good communication quality when amplifying cellular network signals and satellite signals.
[0067] When designing a cellular antenna, you can consider frequency band selection, antenna type and size, performance optimization, environmental factors and interference. Through reasonable design and optimization, you can ensure that the cellular antenna has stable performance and good signal transmission capabilities when transmitting cellular signals and satellite signals.
[0068] Step S220: Receive the satellite signal to a satellite signal demodulator using the second signal link, wherein the satellite demodulator is arranged in the first signal link and is used to demodulate the received satellite signal.
[0069] Here, the satellite signal demodulator, also known as the demodulation part in the satellite modem, is a device used to convert the analog signal transmitted by the satellite back into a digital signal. In a satellite communication link, the demodulator receives the analog signal transmitted via the satellite link and uses demodulation technology to restore it to the original digital data for processing and use at the receiving end.
[0070] In the implementation process, a connection circuit can be set between the satellite demodulator and the cellular network antenna so that the satellite demodulator can receive satellite signals through the cellular network antenna. In some embodiments, a bandpass filter adapted to the satellite signal can also be set on the connection circuit to filter out other stray signals except the satellite signal, thereby improving the working efficiency of the satellite demodulator.
[0071] In an embodiment of the present application, a second signal link can be used to receive satellite signals to a satellite signal demodulator, so as to realize multiplexing of the cellular antenna of the second signal link to receive satellite signals in a satellite communication mode, thereby effectively improving the strength of the received satellite signal, that is, improving the ability of the electronic device to receive satellite signals.
[0072] In some embodiments, in the above step S130, “communicating with the satellite through the first signal link and communicating with the satellite through the second signal link based on the satellite communication mode”, for example Figure 3 As shown, this can be achieved by following the steps below:
[0073] Step S310: communicating with the satellite through the first signal link;
[0074] Here, the first signal link is a signal link with satellite communication capability. In the satellite communication mode, communication with the satellite can be performed through the first signal link.
[0075] Step S320: Switch the working mode of the second signal link based on the satellite communication mode to enable the second signal link to communicate with the satellite.
[0076] Here, the second signal link can transmit and receive cellular network signals in a cellular network communication mode when in a non-satellite communication mode.
[0077] In the satellite communication mode, the working mode of the second signal link can be switched so that the devices on the second signal link can process satellite signals and realize communication between the second signal link and the satellite.
[0078] In an embodiment of the present application, communication with the satellite is carried out through a first signal link; by switching the working mode of the second signal link based on the satellite communication mode, it is possible to increase the number of channels capable of satellite communication by only setting the second signal link to adapt to satellite communication, thereby effectively improving the efficiency and quality of satellite communication.
[0079] In some embodiments, the above step S320 "switching the working mode of the second signal link based on the satellite communication mode to enable the second signal link to communicate with the satellite" can be implemented by the following steps:
[0080] Step 321: adjusting the operating frequency band of the signal amplifier and the modem arranged on the second signal link to the satellite signal frequency band based on the satellite communication mode;
[0081] Here, the signal amplifier on the second link can be configured to amplify not only the signal in the cellular network frequency band but also the signal in the satellite frequency band.
[0082] The working principle of a modem can be divided into two functions: modulation and demodulation. Modulation is the conversion of digital data (such as binary numbers generated by a computer) into a form suitable for sending on an analog signal transmission medium. The modem can select a modulation method to convert the digital signal into an analog signal. After selecting the modulation method, the modem converts the digital signal into a corresponding analog signal. This analog signal can be sent via radio waves. In the implementation process, the frequency band of the analog signal can be set to match the frequency band of the satellite signal.
[0083] Demodulation is the reverse process of the modem, which converts the received analog signal back to the original digital signal. Based on the pre-selected modulation method, the demodulator selects the corresponding demodulation technology. For example, if the modulation is phase modulation, the demodulator can use the corresponding demodulation algorithm to restore the analog signal. The analog signal is converted into a stable digital signal as output. In the implementation process, the demodulator can be set to use a preset demodulation algorithm to restore the signal of the satellite band to a digital signal.
[0084] During implementation, when the electronic device is in satellite communication mode, the operating frequency band of the signal amplifier and modem set on the second signal link (cellular network signal link) can be adjusted to the satellite signal frequency band to enable communication with the satellite using the second signal link.
[0085] Step 322: Communicate with the satellite via the second signal link.
[0086] In the embodiment of the present application, the operating frequency band of the signal amplifier and modem set on the second signal link is adjusted to the satellite signal frequency band based on the satellite communication mode. In this way, by setting the operating mode of the signal amplifier and modem of the cellular network signal link, the second signal link can communicate with the satellite, effectively improving the quality and efficiency of the communication between the electronic device and the satellite.
[0087] In some embodiments, the above step S110 “obtaining the first trigger signal” can be implemented by one of the following steps:
[0088] Step 111: When it is determined that the received cellular network signal is less than a first signal threshold, trigger the satellite communication mode to generate the first trigger signal;
[0089] or,
[0090] During implementation, the first signal threshold can be set according to the actual usage needs of the user. When the electronic device determines that the received cellular signal is less than the first signal threshold, the satellite communication mode can be automatically triggered and a first trigger signal can be generated. For example, when the user is in an environment with a poor cellular network signal and cannot use the electronic device normally, or when the cellular network signal cannot continuously provide communication for the user, the electronic device can automatically trigger the satellite communication mode to enable the user to automatically trigger the satellite communication mode of the electronic device when the user needs help, and send out the distress signal pre-set by the user.
[0091] Step 112: Obtain the first trigger signal.
[0092] In some embodiments, a trigger button may be provided on the electronic device to obtain a first trigger signal in response to a user's operation of triggering the button. The trigger button may be a virtual button provided on the electronic device, or a mechanical button provided on the electronic device. There is no restriction on the form of button setting, and the button is provided to the user in a prominent display manner so that the button can be quickly triggered when the user is in a rescue environment.
[0093] In the embodiment of the present application, when it is determined that the received cellular network signal is less than the first signal threshold, the satellite communication mode is triggered to generate a first trigger signal. In this way, the electronic device can automatically trigger the satellite communication mode. The first trigger signal can also be obtained directly. In this way, the user can trigger the first trigger signal by operating the electronic device, providing the user with flexible and diverse methods for triggering the satellite communication mode.
[0094] In some embodiments, the above signal transceiving method further includes the following steps:
[0095] Step S140: Determine whether the received satellite signal is greater than a second signal threshold;
[0096] Here, the second signal threshold can be set according to the actual usage requirements of the user. The received satellite signal is compared with the second signal threshold to determine whether the received satellite signal is greater than the second signal threshold. When it is determined that the satellite signal is greater than the second signal threshold, it can be determined that the satellite signal sent by the electronic device has been successfully transferred by the satellite, that is, the sent satellite signal is sufficient to support effective communication between the electronic device and the satellite.
[0097] Step S150, triggering a second trigger signal;
[0098] Here, the second trigger signal can be used to close a signal link to reduce the power consumption of the electronic device and extend the use time of the electronic device.
[0099] In some embodiments, when it is determined that the satellite signal is greater than the second signal threshold, the generation of the second trigger signal may be automatically triggered.
[0100] In some embodiments, when it is determined that the satellite signal is greater than the second signal threshold, a prompt message can be output to prompt the user to set a second trigger signal to reduce the signal transceiver link and save energy consumption of the electronic device.
[0101] Step S160: In response to the second trigger signal, communicate with the satellite through the first signal link or the second signal link.
[0102] During the implementation process, since the signal sent by the electronic device can be received and relayed by the satellite, and the electronic device also receives the satellite signal, it can be determined that the electronic device has completed the closed-loop distress signal sending and receiving, so the signal link with the satellite communication can be closed to effectively reduce the power consumption of the electronic device. Maintaining the effective power of the electronic device in the wild environment is also very important for the communication of the electronic device.
[0103] For example, when a user is unable to use cellular network signals in the wild and triggers the satellite communication mode, the user can set the satellite mode and use multiple signal links of the electronic device, including the signal link of cellular network communication, for satellite communication. When it is determined that the distress signal of the electronic device has been received, the channel for satellite communication can be closed sequentially to achieve the effect of energy saving and power saving.
[0104] In the embodiment of the present application, it is determined that the received satellite signal is greater than the second signal threshold; the second trigger signal is triggered; in response to the second trigger signal, communication is performed with the satellite via the first signal link or the second signal link. In this way, it can be determined that the electronic device has completed the closed-loop distress signal transmission and reception, and the signal link for communication with the satellite is closed, thereby effectively reducing the power consumption of the electronic device, so that the electronic device can effectively extend the use time. Maintaining the effective power of the electronic device in the field environment is also very important for the communication of the electronic device.
[0105] Figure 4 A schematic diagram of a circuit for sending and receiving signals provided in an embodiment of the present application, such as Figure 4 As shown, the circuit diagram includes: a satellite signal transceiver link 41 and two cellular network signal transmission links 42, wherein:
[0106] The satellite signal transceiver link 41 includes a satellite transceiver 411, a satellite power amplifier 412, a satellite transceiver switch 413 and a satellite antenna 414. By switching the satellite transceiver switch, the satellite signal transceiver link can realize satellite communication function by using a satellite antenna 414 in the time division multiple access mode.
[0107] Each cellular network signal transmission link 42 includes a cellular network transceiver 421 , a cellular network power amplifier 422 , a satellite or cellular network signal divider 423 and a cellular network antenna 424 .
[0108] When the satellite communication mode is set, the process of transmitting the satellite signal is as follows: the satellite transmission signal of the satellite signal transceiver link 41 can couple the satellite signal to the input port of the N-port power divider 46 through the coupler 44, and then send it to the input port of the signal switching switch 43 through the output port of the N-port power divider 46. The signal switch 43 is set to the satellite communication mode so that the coupled satellite signal can be input into the input ends of the two cellular network signal amplifiers 422 respectively, and then sent to the cellular network antenna through the two satellite or cellular network signal dividers 423 to realize the sending of the satellite signal.
[0109] Here, since there is no cellular network signal in the general use of SOS scenario, the cellular network antenna and cellular network power amplifier and other modules are in an idle state.
