Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a communication system, method and terminal device. Background Art

[0002] With the development and progress of technology, the functions of terminal devices are gradually improved and enriched. More and more smartphones support two-way Beidou satellite messaging technology. In an environment without a ground network, messages can be sent and received through Beidou satellites, and two-way information communication can be carried out with other smartphones, providing users with communication guarantee in an environment without a ground network.

[0003] Since Beidou satellite messages are communicated via satellite links, there are still some problems to be solved compared to ground network communications. For example, when users use smartphones to send or receive satellite messages in the wild, they need to complete multiple steps such as capturing and tracking satellites, which has a great impact on the power consumption of smartphones and will reduce the battery life of the phone. Users will consider the battery life of their smartphones and will not send or receive satellite messages frequently, which will result in the inability to contact other users in a timely manner, affecting the user experience. Summary of the invention

[0004] The present application provides a communication system, method and terminal device, which form a group with other terminal devices and query the satellite messages to be received by all terminal devices in the group according to the group identifier, thereby simplifying the sending operation of satellite messages, reducing the power consumption of terminal devices, improving the real-time performance of receiving satellite reply messages, and more effectively ensuring the communication activities of users in outdoor activities.

[0005] The above-mentioned and other objects are achieved by the features of the independent claims, with further implementations being apparent from the dependent claims, the description and the drawings.

[0006] In a first aspect, a communication system is provided, the system comprising a target terminal device and a server, wherein the target terminal device is used to send a first request message to a satellite, the first request message comprising an identifier of the first group, wherein the target terminal device is in a state of no network connection, and the first group comprises a plurality of terminal devices; the server is used to receive the first request message from the target terminal device via a satellite, determine one or more terminal devices in the first group having a satellite message to be received according to the identifier of the first group in the first request message, and return a first response message to the target terminal device via the satellite, the first response message comprising indication information, and the indication information is used to indicate the one or more terminal devices; the target terminal device is used to receive the first response message via a satellite, and display user information corresponding to the one or more terminal devices according to the indication information in the first response message.

[0007] Specifically, the target terminal device and the first terminal device and the second terminal device can form a group in a network state. For example, a user can log in to the terminal device, create a group through an instant messaging application APP (such as Changlian APP), and invite friends to join the group. After the friends agree to join, they form the same group with the terminal devices logged in by the friends. Among them, the correspondence between the group identifier and the user identifier corresponding to each terminal device in the group is saved in the server (such as Changlian server), and the correspondence between the user identifier corresponding to each terminal device in the first group and the user nickname is saved in the target terminal device. In some embodiments, the user identifier corresponding to the terminal device may include but is not limited to: the user's mobile phone number, the unique ID assigned to the user by the server, etc.; the group identifier may include but is not limited to: the unique ID assigned to the group by the server, the group name, etc. Users can join different groups, so that they can easily form groups with different terminal devices and travel in different groups, which improves the flexibility of travel and enhances the user experience.

[0008] When all devices in the group are in a no-network state, the target terminal device can receive the satellite message to be received by the terminal devices in the group by actively querying. In some embodiments, by providing a control for receiving group satellite messages on the interface of the target terminal device, the user can actively click the control, so that the target terminal device can send a letter query request message to the satellite, and the query request message includes a group identifier; the server obtains the group identifier in the request message, and obtains one or more user identifiers under the group according to the correspondence between the group identifier and the user identifiers corresponding to each terminal device in the group; queries whether there is a message to be received sent to the terminal device identified by the user identifier based on the obtained one or more user identifiers; when it is queried that the terminal device identified by one or more user identifiers in the group has a satellite message to be received, the server returns a first response message to the target terminal device through the satellite, and the first response message includes a user identifier list, and the terminal device identified by any user identifier in the user identifier list has a satellite message to be received.

[0009] After receiving the first response message, the target terminal device obtains the user identification, obtains the user nickname list corresponding to the terminal devices in the first group that have to-be-received satellite messages through the corresponding relationship between the user identification and the user nickname corresponding to each terminal device in the first group stored in the target terminal device, and displays the user nickname list on the target terminal device. In this way, the user in the first group can obtain whether all devices in the group have to-be-received satellite messages through the target terminal device, and if so, display them on the target terminal, without the need for each device in the group to send a letter query request message to query whether there is a satellite message to be received.

[0010] Therefore, the system can expand the application scenarios of satellite messages and realize the reception of group satellite messages by target terminal devices in the group when multiple terminal devices form a group, thereby improving the communication guarantee of multiple terminal devices.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the first response message also includes the number of satellite messages to be received by the terminal device identified by any user identifier in the user identifier list, and the target device displays the number of satellite messages to be received based on the first response message.

[0012] Specifically, based on the query of the satellite messages to be received by the terminal devices identified by one or more user identifiers in the group, the server counts the satellite messages to be received by the terminal devices identified by each user identifier, obtains the number of satellite messages to be received by the terminal devices identified by the user identifier, and returns it to the target terminal device through the first response message; after receiving the first response message, the target terminal device obtains the number of satellite messages to be received in the first response message, and displays it on the screen with the corresponding user nickname. According to this implementation method, the user can intuitively see the number of satellite messages to be received on the target terminal device, further improving the user experience.

[0013] In combination with the first aspect, in some implementations of the first aspect, the user information includes a user nickname.

[0014] According to this implementation, the target terminal device can display the user nicknames corresponding to one or more terminal devices when displaying, which improves the friendliness of the interface and further improves the user experience.

[0015] In combination with the first aspect, in some implementations of the first aspect, the multiple terminal devices include the target terminal device.

[0016] Specifically, the target terminal device may also be a device of the first group, and does not need to be bound with terminal devices outside the group. According to this implementation, the user can form a group more flexibly.

[0017] In combination with the first aspect, in certain implementations of the first aspect, displaying the user information corresponding to the one or more terminal devices according to the indication information in the first response message includes: obtaining the user information according to the indication information, and displaying the obtained user information.

[0018] In this implementation, the target terminal device obtains corresponding user information, such as a user nickname, through knowledge information based on the indication information in the first response message, such as the user identifiers corresponding to one or more terminal devices, or the user number corresponding to the user identifier. According to this implementation, the target terminal device can display specific user information when displaying, which improves the friendliness of the interface and further improves the user experience.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the indication information includes a user identifier corresponding to the one or more terminal devices, or a user number corresponding to the user identifier, wherein the number of bytes occupied by the user number corresponding to any user identifier is less than the number of bytes occupied by the user identifier.

[0020] Specifically, the user identification is usually a long string of numbers automatically generated by the server, and the satellite message is subject to the limitations of satellite communication and has requirements on the length of the response message. In order to reduce the number of bytes occupied by the user identification, the user identification is converted into a user number that occupies fewer bytes, that is, the number of bytes occupied by the user number is less than the number of bytes occupied by the user identification. According to this implementation, it is helpful to add more content to the indication information for indicating one or more terminal devices. In combination with the first aspect, in some implementations of the first aspect, the indication information is also used to indicate the number of satellite messages to be received by the users to which the one or more terminal devices belong, and / or the number of satellite messages to be received by the one or more terminal devices.

[0021] Specifically, based on inquiring that the terminal devices identified by one or more user identifiers in the group have satellite messages to be received, the server counts the satellite messages to be received by the terminal devices identified by each user identifier, obtains the number of satellite messages to be received by the terminal devices identified by the user identifier, and returns it to the target terminal device through a first response message; after receiving the first response message, the target terminal device obtains the number of satellite messages to be received in the first response message, and displays it on the screen together with the corresponding user nickname.

[0022] In combination with the first aspect, in some implementations of the first aspect, the indication information includes the user information;

[0023] The displaying of the user information corresponding to the one or more terminal devices according to the indication information in the first response message includes: displaying the user information in the indication information.

[0024] Specifically, the indication information may include a user nickname, and the target terminal device displays the user nickname in the indication information. In one implementation, the server may obtain the user nickname of the user identifier corresponding to the terminal device with the to-be-received satellite message in the first group according to the user identifier and the corresponding relationship between the user identifier and the user nickname corresponding to each terminal device in the first group stored in the server, and return it to the target terminal device through the first response message; after receiving the first response message, the target terminal device obtains the user nickname in the first response message and displays it on the screen. After receiving the user nickname in the first response message, the target terminal device may not search for the corresponding relationship between the user identifier and the user nickname stored on the device according to the user identifier, but may directly obtain it from the response message. When the storage cannot be accessed, the user experience is not affected, which not only improves the processing speed, but also improves the communication guarantee of the user.

[0025] In combination with the first aspect, in some implementations of the first aspect, the indication information is sorted according to the latest reception time of the to-be-received satellite messages of the users to which the one or more terminal devices belong.

[0026] Specifically, the terminal device identified by the user identifier in the user identifier list may correspond to one or more satellite messages to be received. The server obtains the reply time of the most recent satellite message to be received corresponding to each user identifier, and sorts the user identifiers in the user identifier list according to the time, placing the user identifier with the most recently received satellite message in front, so that the target terminal device displays information in the order of the time of the most recent satellite message received.

[0027] In combination with the first aspect, in some implementations of the first aspect, the first response message also includes a first satellite message of a first terminal device among the one or more terminal devices.

[0028] Specifically, the server can also find at least one stored satellite message according to at least one user identifier in the list, and return the at least one found satellite message to the target terminal device through a first response message. The user can directly read the content of the satellite message to be received on the target terminal device, and the user does not need to read it again through the terminal device. While facilitating the user, it also solves the problem of being unable to obtain the satellite message to be received due to a terminal device failure or a terminal device out of power.

[0029] In combination with the first aspect, in some implementations of the first aspect, the target terminal device has the functions of autonomous satellite search and satellite communication.

[0030] Specifically, the target terminal device has a module with the function of autonomous satellite search and satellite communication, such as an antenna installed in the target terminal device and other hardware that can realize the operation of automatically searching for satellites, and can automatically receive reply messages from Beidou satellites without the user having to perform frequent operations, such as without the user having to actively click to receive messages in the Changlian APP installed on the mobile phone. In conjunction with the first aspect, in some implementations of the first aspect, the target terminal device is a smart car.

[0031] Specifically, the target terminal device is a smart car. Compared with a mobile phone, a smart car has a much larger battery capacity and is not sensitive to power-consuming operations such as autonomous satellite search, and can continuously perform operations such as automatic satellite search.

[0032] In combination with the first aspect, in certain implementations of the first aspect, after receiving the first response message, the smart car notifies by flashing lights and / or honking a horn.

[0033] Specifically, after the first response message, the smart car can notify the group members outside the car by flashing lights and / or honking the horn. This embodiment is suitable for parking scenarios in outdoor signal-free environments. Users in the first group can move within a certain range of the smart car and do not need to sit in the car waiting for messages. They can flexibly check unread messages 24 hours a day.

[0034] In combination with the first aspect, in some implementations of the first aspect, the smart car sends the first request message according to a first time interval.

[0035] Specifically, the user can also set a time interval on the smart car so that the smart car can regularly connect to the Beidou satellite to send a letter query request message for querying group reply messages according to the set time interval. The user can receive notifications of unread satellite messages in a timely manner.

[0036] In combination with the first aspect, in certain implementations of the first aspect, the smart car device sends the first request message according to the first time interval, and notifies by flashing lights and / or honking a horn after failing to receive the first response message for N consecutive times, where N is a preset positive integer.

[0037] Specifically, the user can set a continuous connection failure reminder on the smart car. When the smart car sends a letter query request message according to the set time interval, if it does not receive a letter query response message for N consecutive times (N is a preset number of times), the smart car will notify by flashing lights and honking the horn to prevent users in the group from thinking that the devices in the group have no messages to receive.

[0038] In combination with the first aspect, in some implementations of the first aspect, the first response message is a Beidou satellite message.

[0039] Specifically, the first response message is a Beidou satellite message, and the server sends the first response message to the target terminal device via the Beidou satellite.

The mobile communication module 150 can also amplify the signal modulated by the modulation and demodulation processor, and convert it into electromagnetic waves for radiation through the antenna 1. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the processor 110. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the same device as at least some of the modules of the processor 110.

[0097] The wireless communication module 160 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (WiFi) networks), bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., which are applied to the electronic device 100. The wireless communication module 160 can be one or more devices integrating at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, modulates the frequency of the electromagnetic wave signal and performs filtering, and sends the processed signal to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, modulate the frequency of it, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0098] The electronic device 100 implements the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which connects the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs that execute program instructions to generate or change display information.

[0099] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), Miniled, MicroLed, Micro-oLed, a quantum dot light-emitting diode (QLED), etc. In some embodiments, the electronic device 100 may include one or more display screens 194.

[0100] In some embodiments of the present application, when the display panel is made of materials such as OLED, AMOLED, FLED, etc., the above Figure 1The display screen 194 in the embodiment can be bent. Here, the display screen 194 can be bent, which means that the display screen can be bent to any angle at any position and can be kept at the angle. For example, the display screen 194 can be folded in half from the middle to the left or right. It can also be folded in half from the middle to the top or bottom.

[0101] The display screen 194 of the electronic device 100 can be a flexible screen. At present, the flexible screen has attracted much attention for its unique characteristics and huge potential. Compared with traditional screens, flexible screens have the characteristics of strong flexibility and bendability, which can provide users with a new interaction method based on bendable characteristics, and can meet users' more needs for electronic devices. For electronic devices equipped with a foldable display screen, the foldable display screen on the electronic device can be switched between a small screen in a folded form and a large screen in an unfolded form at any time. Therefore, users use the split-screen function on electronic devices equipped with a foldable display screen more and more frequently.

[0102] The electronic device 100 can realize the shooting function through the ISP, the camera 193, the video codec, the GPU, the display screen 194 and the application processor.

[0103] The ISP is used to process the data fed back by the camera 193. For example, when taking a photo, the shutter is opened, and the light is transmitted to the camera photosensitive element through the lens. The light signal is converted into an electrical signal, and the camera photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also perform algorithm optimization on the noise, brightness, and skin color of the image. The ISP can also optimize the exposure, color temperature and other parameters of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0104] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the optical signal into an electrical signal, and then passes the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include one or more cameras 193.

[0105] The digital signal processor is used to process digital signals, and can process not only digital image signals but also other digital signals. For example, when the electronic device 100 is selecting a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy.

[0106] Video codecs are used to compress or decompress digital videos. The electronic device 100 may support one or more video codecs. Thus, the electronic device 100 may play or record videos in a variety of coding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

[0107] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function, such as storing music, video and other files in the external memory card.

[0108] The internal memory 121 can be used to store one or more computer programs, which include instructions. The processor 110 can enable the electronic device 101 to perform the methods provided in some embodiments of the present application, as well as various applications and data processing, etc. by running the above instructions stored in the internal memory 121. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area can store an operating system; the program storage area can also store one or more applications (such as a gallery, contacts, etc.). The data storage area can store data (such as photos, contacts, etc.) created during the use of the electronic device 101. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more disk storage components, a flash memory component, a universal flash storage (UFS), etc. In some embodiments, the processor 110 can enable the electronic device 101 to perform the methods provided in the embodiments of the present application, as well as other applications and data processing by running instructions stored in the internal memory 121, and / or instructions stored in a memory provided in the processor 110. The electronic device 100 can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0109] 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, and the like.

[0110] Among them, the pressure sensor 180A is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, the pressure sensor 180A can be set on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. The capacitive pressure sensor can be a parallel plate including at least two conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the touch operation intensity according to the pressure sensor 180A. The electronic device 100 can also calculate the touch position according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities can correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, an instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, an instruction to create a new short message is executed.

[0111] The gyro sensor 180B can be used to determine the motion posture of the electronic device 100. In some embodiments, the angular velocity of the electronic device 100 around three axes (i.e., X, Y, and Z axes) can be determined by the gyro sensor 180B. The gyro sensor 180B can be used for anti-shake shooting. For example, when the shutter is pressed, the gyro sensor 180B detects the angle of the electronic device 100 shaking, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to offset the shaking of the electronic device 100 through reverse movement to achieve anti-shake. The gyro sensor 180B can also be used for navigation and somatosensory game scenes.

[0112] The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in all directions (generally three axes). When the electronic device 100 is stationary, the magnitude and direction of gravity can be detected. It can also be used to identify the posture of the electronic device and is applied to applications such as horizontal and vertical screen switching and pedometers.

[0113] The ambient light sensor 180L is used to sense the ambient light brightness. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the perceived ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor 180L can also cooperate with the proximity light sensor 180G to detect whether the electronic device 100 is in a pocket to prevent accidental touches.

[0114] The fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can use the collected fingerprint characteristics to implement fingerprint unlocking, access application locks, fingerprint photography, fingerprint call answering, etc.

[0115] The temperature sensor 180J is used to detect temperature. In some embodiments, the electronic device 100 uses the temperature detected by the temperature sensor 180J to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 reduces the performance of a processor located near the temperature sensor 180J to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 heats the battery 142 to avoid abnormal shutdown of the electronic device 100 due to low temperature. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 performs a boost on the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

[0116] The touch sensor 180K is also called a "touch panel". The touch sensor 180K can be set on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, also called a "touch screen". The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K can also be set on the surface of the electronic device 100, which is different from the position of the display screen 194.

[0117] Figure 2 1 is a software structure diagram of the electronic device 100 of the embodiment of the present application. The layered architecture divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer.

[0123] The view system includes visual controls, such as controls for displaying text, controls for displaying images, etc. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

[0124] The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including connecting, hanging up, etc.).

[0125] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0126] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0127] The system library may include multiple functional modules, such as surface manager, media libraries, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0128] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0129] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG and PNG, etc.

[0131] A 2D graphics engine is a drawing engine for 2D drawings.

[0132] 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.

[0133] In order to facilitate understanding of the communication method provided by this application, the following Figures 3 to 13 The content shown introduces the implementation process of the method provided by this application.

[0134] Before introducing the embodiments of the present application, the technical terms related to the embodiments of the present application are first introduced:

[0135] Letter query mechanism: Based on the mobility of Beidou satellites, the Beidou satellite communication system is a non-resident communication system, and the Beidou satellite to which the terminal device is generally connected switches as the Beidou satellite moves. Therefore, the downlink transmission of the Beidou network is generally implemented using a letter query mechanism. In this scenario, when the server receives a message sent to a terminal device that is not connected to the network, it can generally store the message first and wait for the terminal device's letter query request. It can be understood that the terminal device actively sends a letter query request message to the connected Beidou satellite. The letter query request message is used by the terminal device to request the download of the satellite message to be received; after receiving the letter query request message, the Beidou satellite can Figure 3 The Beidou satellite ground information processing center 303 and server 304 shown query whether there is a letter stored in the terminal device. If there is, the server 304 sends the letter to the Beidou satellite through the Beidou satellite ground information processing center 303; finally, the Beidou satellite sends the letter to the terminal device.

[0136] In the method provided in the embodiment of the present application, in a satellite communication scenario in which Beidou satellite messages are used for communication, based on a group composed of multiple terminal devices, the group identifier is used to actively query the satellite messages to be received by all terminal devices in the group, thereby expanding the application scenarios of satellite messages, providing better communication guarantees for users traveling together in the wild, and improving the user's communication experience. Figure 3 Several possible application scenarios involved in the embodiments of the present application are introduced.

[0137] Scenario A: Creating a Beidou satellite group based on ground network communication.

[0138] In the present application embodiment, Figure 3As shown in scenario B, before sending a Beidou satellite message, mobile phone 101 can invite other terminal devices (such as mobile phone 301B, mobile phone 301C, mobile phone 301D, target terminal device 301E, etc.) to create a group in the presence of a ground network.

[0139] refer to Figure 4 , which is a schematic diagram of an interface for the process of creating a Beidou satellite group provided in an embodiment of the present application.

[0140] (1) Create a group, refer to Figure 4 (1).

[0141] Mobile phone 301A is the mobile phone currently used by user Zhang San, and a group can be created through an instant messaging application APP (such as Changlian APP) installed on mobile phone 301A. The home page interface 410 of Changlian APP includes a "Beidou satellite group" card 411. In response to the user clicking the "Beidou satellite group" card 411, mobile phone 301A can jump to interface 420 to display the management page of the Beidou satellite group.

[0142] Interface 420 includes a "Beidou Satellite Group" card 421 and a "Create Group" control 422, where card 421 is used to display the information of the Beidou satellite group that has been created. If the user clicks on any group name, the system jumps to the detailed management page of the group; control 422 is used to create a new Beidou satellite group. In response to the user's click operation on card 421, it can jump to interface 430 to create a new Beidou satellite group.

[0143] Interface 430 includes a "group name" control 431 and a "profile" control 432, which are used to record basic information of the group. The user can fill in a suitable group name and profile. For example, if you need to invite friends to go on a jungle adventure, you can name the group "Jungle Adventure Tour". When friends receive the invitation message, they can see the corresponding group name and profile and better understand the purpose of the invitation.

[0144] The interface 430 also includes a "bind target device" control 435, a target terminal device name control 434, and a target terminal device description text 440. Among them, the control 435 is used for the user to select the target terminal device to be bound. The target terminal device can be a smart car with the function of autonomously searching for stars (autonomous tracking and capturing) Beidou satellites and satellite communication functions, or it can be the group creator's own mobile phone (such as mobile phone 301A or mobile phone 301B, etc.), or other terminal devices used by group members. This application does not limit the type of target terminal device; the description text 440 is used to inform the user of the purpose of binding the target terminal device. After binding, the target terminal device can receive the number of unread messages of all terminal devices in the group; the control 434 is used for the user to edit the name of the target terminal device. For example, if the user using mobile phone 301A is called Zhang San, when binding his smart car, he can name it "Zhang San's smart car". When a friend receives an invitation message, he can see the name of the bound target terminal device, so that he can more conveniently know which device is the target terminal device to receive the unread messages of all devices in the group.

[0145] The interface 430 also includes a "Friends List" control 437 and a "Search Friends" control 436. Among them, the "Friends List" control includes a card 438 that displays the friend's name and a "Send Group Invitation" control 439. The user can click on the control 439 to choose whether to add the friend to the group. If the control 439 is checked, the corresponding user will be sent a group invitation when the group is created. For example, the control 439 corresponding to the current friends Li Si and Wang Wu is checked, indicating that Li Si and Wang Wu will receive a request message to invite them to join the group. When there are too many friends and it is inconvenient to find them, you can use the search control 436 to search for friends, and you can set the control 439 corresponding to the friend to a checked state in the search results. In one case, the friends in the friend list are sorted by the first letter of their name, which is convenient for users to select friends.

[0146] When the user completes the preparations for creating a group on the mobile phone 301A as described above, and clicks the "Create Group" control 433, the mobile phone 301A responds to the user clicking the control 433 by sending a request message to create a group to the Changlian server, wherein the request message includes the group name and profile of the group, the device identifier for creating the group (such as the unique device identifier Unique Device Identifier, UDID), and the user identifier of the device logged in (also known as the user account), the user identifier can be a user account or a mobile phone number, wherein the user account can specifically be a user account of the communication system in this example, and this embodiment does not impose specific restrictions on the user identifier. After receiving the request message from the first terminal device, the Changlian server sends the device identifier of the first terminal device, the user identifier for logging in to the first terminal device, and the user nickname corresponding to the user identifier to the target terminal device for storage, i.e., binds the information of the first device to the target terminal device. After completing the binding of the target terminal device, an invitation message is sent to the friends who need to join the group for invitation confirmation. If the Changlian server fails to bind the target terminal device, for example, the target terminal device does not receive a response message from the target terminal device (such as a network anomaly), the Changlian server will send a response message to notify mobile phone 301A that the group creation failed and that it is necessary to re-initiate the group creation request or change the target terminal device to be bound. It should be noted that the user can create multiple groups, and the target terminal device can also be bound to multiple groups.

[0147] (2) Friends agree to join the group, refer to Figure 4 (2).

[0148] Mobile phone 301B is the mobile phone that friend Xiao Chen is using. The Changlian APP installed on mobile phone 301B receives an invitation to join the group sent by the Changlian server. The home page interface 460 of the Changlian APP includes a reminder mark 461, which can be used, for example, to remind in the form of a red dot or a number. This application does not limit the form of reminder. Remind the user of receiving new information. After seeing this mark, the user clicks the "Beidou Satellite Group" card. In response to the user's click operation on the "Beidou Satellite Group" card, mobile phone 301B can jump to interface 470 to display the management page for joining the group.

[0149] Interface 470 includes Beidou satellite group information control 471, bound target terminal device control 472, and group authorization description card 473. Control 471 is used to display basic information of the group, including group name and introduction; control 472 is used to display the bound target terminal devices in the group; card 473 displays the group authorization description text.

[0150] Interface 470 also includes an "Agree" control 474 and a "Reject" control 475. In response to the user's click operation on control 474, mobile phone 301B sends a response message of agreeing to join the group to the Changlian server, wherein the response message includes the device identification of mobile phone 301B, Xiao Chen's user identification and user nickname, and authorization information for authorizing the target terminal device to receive the Beidou satellite message replied to Xiao Chen. After receiving Xiao Chen's message of agreeing to join the group, the Changlian server stores the correspondence between the group identification and the user identification and device identification on the server, and sends the received device identification, Xiao Chen's user identification and user nickname and other information of mobile phone 301B together with the group identification to the target terminal device, and the target device associates and stores the information after receiving the information of mobile phone 301B. If the user clicks the "Reject" control 475, mobile phone 301B responds to the user's click operation on control 475 and sends a response message of refusing to join the group to the Changlian server. After receiving the rejection message, the Changlian server records the rejection operation, and the user will not join the group.

[0151] In some embodiments, the user can also enter a reason for rejection after clicking control 475, and the reason for rejection will be returned to the Changlian server through a response message so that the group creator knows the reason why the friend refuses to join the group.

[0152] It should be noted that a user can receive multiple invitations to join multiple groups, and the target terminal device can also be bound to multiple groups.

[0153] (3) Query group information, refer to Figure 4 (3).

[0154] After mobile phone 301A and mobile phone 301B join the same group, they can view group information through the Changlian APP installed on the mobile phone. Taking mobile phone 301A as an example, the user clicks on the Beidou satellite group "Outdoor Adventure Tour" card 491 on interface 490, and the mobile phone responds to the click operation on card 491 and jumps to interface 4100 to manage the "Outdoor Adventure Tour" group or manage the messages of the Beidou satellite group.

[0155] Interface 4100 includes a "Group Management" card 4101 and a "Message Management" card 4102. In response to the user clicking on card 4102, mobile phone 301A jumps to group management interface 4110. Group management interface 4110 includes basic group information and friend list information, and the user can view the basic information of the group through this interface. If the user who logs in to the Changlian APP is the creator of the group, controls 4111, 4112, and 4113 will be displayed on interface 4110, which are used to modify the group name, delete the group, and change the bound target terminal device respectively.

[0156] In response to the user clicking on card 4102, mobile phone 301A jumps to interface 4120 to receive Beidou satellite messages. Interface 4120 includes a "receive message" control 4121 for receiving Beidou satellite messages.

[0157] In some embodiments, the device receiving the group message may be a smart car that has the function of autonomously capturing and tracking Beidou satellites. Compared with mobile phones, smart cars have much larger battery capacity, so they are not sensitive to the power consumption of the device for capturing and tracking satellites, and the antenna and other hardware installed on the smart car can realize the operation of automatically capturing and tracking Beidou satellites, and the user does not need to perform frequent operations to automatically receive the reply message of the Beidou satellite, such as the user does not need to actively click to receive the message in the Changlian APP installed on the mobile phone.

[0158] In addition, users can join multiple groups in the Changlian APP to travel with different friend groups. The way for users to join other groups is the same as the above steps, which will not be repeated here.

[0159] Based on the content introduced in the above scenario A, Figure 5 A schematic diagram of a process of creating a group provided in an embodiment of the present application. The process of the method may include the following steps:

[0160] Step 501: The first terminal device sends a request to create a Beidou satellite group to a Beidou satellite service end (such as a Changlian server).

[0161] The first terminal device may be, for example, Figure 3 The mobile phone 301A shown in the figure, when there is a ground network, sends a request to create a Beidou satellite group to the Changlian server through the Changlian APP installed on the mobile phone. The request message sent includes: the group name and introduction of the group, the user ID and nickname of the group creator, the device ID used by the group creator, and the user ID of the invited friend. After the group creation information is filled in, the group creation request message will send the group creation information to the Beidou satellite server, where the Beidou satellite server is the Changlian server corresponding to the Changlian APP used by the supporting users.

[0162] After receiving the request to create a group, the Changlian server determines whether the target terminal device to be bound has been bound by other groups. The same target terminal device cannot be bound by multiple groups. If the target terminal device to be bound is bound by other groups, the Changlian server returns the creation failure information to the first terminal device and notifies the reason for the creation failure. If the target terminal device to be bound has not been bound by other groups, the Changlian server creates a group identifier, binds the group identifier to the user identifier corresponding to the first terminal device, and saves it. After the group is created, the Changlian server sends the group identifier, the first terminal device identifier, the corresponding user identifier of the first terminal device, and the user nickname to the target terminal device.

[0163] Step S502: the Changlian server sends a target terminal device binding request message to the target terminal device.

[0164] Specifically, after the group is created, the Changlian server sends a target terminal device binding request message to the target terminal device, wherein the target terminal device binding request message includes a group identifier, a first terminal device identifier, a corresponding user identifier of the first terminal device, and a user nickname.

[0165] After receiving the target terminal device binding request message sent by the Changlian server, the target terminal device checks whether there is binding information of the group identifier in the target terminal device according to the received group identifier. If the binding information of the group identifier already exists, it means that the target terminal device has been bound to the group identifier, and the target terminal device returns a binding failure message to the Changlian server; if the binding information of the group identifier does not exist, it means that the target terminal device is not bound to the group identifier, and the target terminal device will save the binding information of the group identifier, and save the group identifier, the first terminal device identifier, the corresponding user identifier and user nickname of the first terminal device in the local database, and return a binding success message to the Changlian server.

[0166] After receiving the successful binding message, the Changlian server will send a notification message to invite friends to join the group. If the Changlian server receives a binding failure or does not receive a response message from the target terminal device due to network anomalies, it will return the creation failure information to the first terminal device and notify the reason for the creation failure.

[0167] Step S503: the Changlian server sends a notification message to invite the second terminal device to join the group.

[0168] Specifically, after receiving the message that the target terminal device is successfully bound, the Changlian server sends a notification message to the second terminal device to invite the friend to join the group. The notification message includes the group name and introduction, and the name of the target terminal device, so that the friend can better understand the group information when joining the group using the second terminal device.

[0169] Step S504: The second terminal device returns a response message agreeing to join the group.

[0170] Specifically, the user agrees to join the group on the Changlian APP of the second terminal device, and the second terminal device sends a response message to the Changlian server to notify the Changlian server that the user agrees to join the group. Among them, the response message includes the following information: the device identifier of the second electronic device, the user identifier and user nickname for logging into the second electronic device, and the authorization information for authorizing the target terminal device to receive the Beidou satellite message replied to the second electronic device. After receiving the response message sent by the second terminal device agreeing to join the group, the Changlian server binds and saves the group identifier with the user identifier and device identifier corresponding to the second terminal device, and sends the second terminal device identifier, the user identifier corresponding to the second terminal device, the user nickname and device identifier to the target terminal device. It can be understood that when the Changlian server saves the group information, it is associated according to the rule that one group identifier can correspond to multiple user identifiers, and one user identifier can correspond to multiple terminal device identifiers. Under this rule, not only can multiple users join the group through different terminal devices, but the same user can also join the group by logging into different terminal devices. Furthermore, when the same user logs in to different terminal devices, the user does not need to confirm the consent on each logged-in terminal device, but only needs to confirm the consent on one of the logged-in terminal devices. After receiving the response message of consent to join the group, the server will also add the identifiers of the other terminal devices logged in by the user to the group information (the user has uploaded the logged-in terminal device identifier to the server when logging in to the terminal device), which simplifies the user's operation and avoids the user from operating on multiple terminal devices.

[0171] If the Changlian server receives a response message from the second terminal device agreeing to join the group, or does not receive a response message returned by the second terminal device due to network reasons or other reasons, it does not need to send the second terminal device and its corresponding user information to the target terminal device.

[0172] Step S505: the Changlian server sends group member information to the target terminal device.

[0173] Specifically, after receiving a response message from the second terminal device agreeing to join the group, the Changlian server sends a notification message to the target terminal device, wherein the notification message includes: a group identifier, a second terminal device identifier, and a user identifier and user nickname corresponding to the second terminal device.

[0174] After receiving the request, the target terminal device determines whether the received group identifier exists on the target terminal device. If so, it associates the second terminal device identifier, the corresponding user identifier and user nickname of the second terminal device with the corresponding group identifier, saves it in the local database, and returns a message of successful saving to the Changlian server.

[0175] Step S506: the Changlian server stores the group relationship.

[0176] After receiving the successful save message from the second terminal device, the Changlian server saves the binding relationship between the second terminal device and the group. At this time, the target terminal device, the first terminal device and the second terminal device form a first group, and the information in the first group includes the corresponding relationship between the identifier of the first group and the user identifier corresponding to each terminal device in the first group.

[0177] Scenario B: Sending satellite messages without ground network.

[0178] When all terminal devices in the group are in a scenario without ground network, they can connect to Beidou satellite based on the communication protocol to realize message sending without network connection.

[0179] refer to Figure 6, which is a schematic diagram of an interface for sending Beidou satellite messages. Taking sending Beidou satellite messages through the Changlian APP on the mobile phone 301B as an example, the user can click on the "Beidou satellite message" card in the homepage interface 610 of the Changlian APP, and the mobile phone 301B responds to the operation and displays the interface 620. In the interface 620, the "use guide" card of the Beidou satellite message can be included, and the "new message" control and the "learn more" control can also be included. The mobile phone 301B can respond to the user's click operation on the "new message" control and display the interface 630 for creating a new Beidou satellite message. In the interface 630, the "Beidou satellite message tips" card can be included, and the display area for selecting a contact in the address book or entering a contact number as the recipient of the Beidou satellite message, the control for carrying location information, the text box for entering the specific text content of the Beidou satellite message, and the common phrases of the Beidou satellite message can also be included; the mobile phone can respond to the click operation of selecting the contact in the address book control and display the interface 640. In interface 640, a list of contacts stored in mobile phone 301B may be included. Mobile phone 301B may update interface 630 to interface 650 in response to the user's operation of selecting contact Li Si and contact Wang Wu, and returning to the interface of creating a new Beidou satellite message. In interface 650, contact Li Si and contact Wang Wu selected by the user may be included. In response to the user's editing operation of inputting text content and the click operation of the "Send" control, the mobile phone displays interface 660. In interface 660, it is used to indicate that the device attitude of mobile phone 301B is aligned with the satellite, so that mobile phone 301B can send a message to the satellite in the form of Beidou satellite message based on the communication protocol without network connection; for example, interface 660 is used to display the sending interface of Beidou satellite message. In response to receiving the satellite receipt, mobile phone 301B can display interface 670; wherein interface 670 is used to indicate that the Beidou satellite message has been sent and the satellite receipt has been received. Finally, mobile phone 301B may display interface 680 ; wherein interface 680 may be an update of interface 620 after the Beidou satellite message is sent. Compared with interface 620 , interface 680 may also include a preview card for displaying the sent Beidou satellite message.

[0180] Scenario C, reply based on instant messaging APP.

[0181] refer to Figure 7, which is a schematic diagram of a Beidou satellite message reply interface provided by an embodiment of the present application. The homepage interface 710 of the Changlian APP included in the mobile phone 305A held by the contact Li Si may include a "Beidou Satellite Message" card; wherein, the "Beidou Satellite Message" card may display a reminder of a new message, for example, in the form of a number or a red dot, etc., and the present application does not limit the reminder method. In response to the touch operation of the "Beidou Satellite Message" card, the mobile phone 305A may display an interface 720. In the interface 720, a preview card 701 may be used to display the Beidou satellite message sent by Zhang San received by the contact Li Si. In the preview card 701, not only the sender information, message content and location information carried by the message obtained based on the Beidou satellite message sent by Zhang San, but also a "Reply" control 7011 may be included; wherein, the "Reply" control 7011 may be used to enable the recipient to reply to the Beidou satellite message from Zhang San on the mobile phone 305A through instant messaging technology. It should be noted that although the received Beidou satellite message is displayed in the form of a message card in interface 720, the display form is not limited in the embodiment of the present application, and it can also be implemented in the form of text content, etc.; and, although the reply to the Beidou satellite message is implemented by including a "reply" control in the message card in interface 720, the display form of the "reply" control is not limited in the embodiment of the present application, and it can also be implemented in the form of a separate control in interface 721 as introduced in subsequent embodiments, or by detecting a reference display when a long press operation on card 701 is detected.

[0182] In another exemplary embodiment, in interface 720, mobile phone 305A may also receive a touch operation on preview card 701, and display interface 721, which is used to display detailed information of Beidou satellite message. Interface 721 may also include a "reply" control 703, which has a similar function to the "reply" control 7011 included in interface 720. It can be understood that in actual implementation, mobile phone 305A may detect and respond to the user's touch operation on "reply" control 7011 in interface 720, and may also detect and respond to the user's touch operation on "reply" control 703 in interface 721, and display interface 730; interface 730 is used for the recipient to reply to the Beidou satellite message from Zhang San.

[0183] In interface 730, mobile phone 305A can be used to detect and respond to the user's editing operation to obtain the reply content input by the user. In addition, in interface 730, mobile phone 305A can also provide a display area 704 for displaying multiple commonly used reply words, so that the user can conveniently select commonly used reply words and edit the reply content. In interface 730, mobile phone 305A can also respond to the user's touch operation on the send control to display interface 740. In other embodiments, mobile phone 305A can also detect and respond to the operation of any commonly used reply words in display area 704, directly triggering the sending of the message, which can save the user's operation.

[0184] In interface 740, preview cards 705 and 707 of reply messages to Zhang San's Beidou satellite message may be included. In some possible embodiments, based on the association relationship between the Beidou satellite message and the reply message, the preview cards 705 and 707 may realize the association display of the reply message based on the received Beidou satellite message, for example, may be displayed in the form of an overlay display as shown in interface 740. In this way, the user can intuitively determine the association relationship between the messages from the display interface.

[0185] As shown above, contact Li Si uses mobile phone 305A to reply to Zhang San's Beidou message. Similarly, contact Wang Wu can use the same operation to reply to Zhang San's Beidou message using mobile phone 305B. For example, after Wang Wu received Zhang San's Beidou message, he replied 3 messages to Zhang San. At this time, 5 unread Beidou messages to Zhang San will be saved in the Changlian server. Similarly, other users in the group also send and receive Beidou messages through scenes B and C, and different users in the group can receive Beidou reply messages from the corresponding contacts.

[0186] Scenario D: Receiving group reply messages without network connection.

[0187] Figure 8A schematic diagram of an interface for receiving unread messages of all members in a group provided in an embodiment of the present application. The receiving device is a smart car. The antenna function of the smart car is more powerful than that of a smart phone. When connecting to a Beidou satellite, there is no need to manually adjust the device posture to align with the satellite. Its sensing device will automatically align with the satellite. Therefore, it has the ability to autonomously capture and track Beidou satellites, and can realize the sending and receiving functions of Beidou satellite messages without the help of user operations. The figure shows the number of unread messages of all members displayed on the central control screen of the smart cockpit of the smart car. In addition, in view of the fact that the smart car can automatically align with the satellite, the user can also set a time interval on the smart car, so that the smart car can regularly connect to the Beidou satellite according to the set time interval (such as 5 minutes) to send a letter query request message for querying the group reply message, and can promptly receive notifications of unread satellite messages, wherein the group reply message includes a user ID, a user nickname, and the number of unread messages corresponding to the user ID. Furthermore, users can also set continuous connection failure reminders on smart cars. When the smart car sends a letter query request message according to the set time interval, and fails to receive a letter query response message for N consecutive times (N is the preset number of times), a reminder can be given on the smart car's central control screen, or a notification can be made by flashing lights or honking horns. Alternatively, if the smart car regularly connects to the Beidou satellite to send a letter query request message, and still fails to receive a letter query response message after the time set by the user, a notification can also be made by using a central control screen prompt, flashing lights, honking horns, etc.

[0188] After receiving the group reply message, the smart car can associate the user information (such as user ID, user nickname, etc.) stored in the smart car according to the user ID in the group reply message, and display prompt information on the central control screen, such as prompting the user how many unread messages there are. After seeing the prompt message, the user can use a smart phone to query and send a letter query request to check the specific message content.

[0189] See also Fig. 9 This is a schematic diagram of an interface for receiving unread messages from all members of a group provided in an embodiment of the present application. The receiving device is a smart phone. Considering that connecting to Beidou satellite consumes a lot of power on the device, affecting the battery life of the device, the smart phone cannot connect to Beidou satellite regularly like a smart car to receive reply messages. Fig. 9 , the user can select "Beidou Satellite Group" in interface 900 to enter the group message operation interface. After clicking "Beidou Satellite Group", the first group message interface is entered, and interface 910 can be displayed at this time. Interface 910 can also include a "Receive Group Message" control 911. The "Receive Group Message" control 911 can be used by the smart phone to actively request the connected Beidou satellite to query whether there are unread messages for each member in the group using a letter query mechanism.

[0190] In response to the user's touch operation on the "receive group message" control 911, the smart phone displays an interface 920. In the interface 920, a prompt for indicating the adjustment of the device posture may be included, such as turning the phone to the right as shown in the interface 920; it may also include a scanned image of a Beidou satellite, a graphic for indicating the device posture, and a reference graphic for indicating that the device is aligned with the satellite, etc. For example, the black ball shown in the interface 920 can be used to indicate the posture of the phone, the fan-shaped area can be used to indicate the target transmission direction of the Beidou satellite message of the phone, and the center circle of the ring can be used to indicate the adjustment of the pitch angle of the phone. After the mobile phone 101 detects that the device posture is aligned with the Beidou satellite, the interface 930 may be displayed; for example, in the interface 930, the scanned image of the Beidou satellite is in the fan-shaped area, and the black ball is in the center circle area of ​​the ring, so it can be used to indicate that the phone posture has been aligned with the Beidou satellite. In the interface 930, it can be used to indicate that the reply message is received successfully. After a preset time, the mobile phone 101 can automatically change to display interface 940. In the interface 940, a preview card for displaying the received reply message may be included. For example, preview card 941 displays information about unread Beidou messages by users in the group.

[0191] It should be noted that Fig. 9 In the introduction, instant messaging APP is used as an example. In actual implementation, a "Receive Group Message" control as shown in interface 900 can also be provided in the interactive window of the Beidou satellite message included in the information APP and other entrances, so that the smartphone can use the letter query mechanism to actively request the connected Beidou satellite to query whether there is a reply message to be received.

[0192] In some embodiments, Fig.10 As shown, after receiving an unread message from the group, the smart car can notify the members in the first group outside the car that the unread message has been received by flashing lights, honking the horn, etc. This embodiment is suitable for parking scenarios in outdoor environments with no signal. Users in the first group can move within a certain range of the smart car and do not need to sit in the car waiting for messages. They can flexibly check unread messages 24 hours a day.

[0193] Scenario E: Distributing Beidou messages without network connection.

[0194] After receiving the group reply message, the target terminal device can obtain the correspondence between the user ID in the group reply message and the number of unread messages, and then obtain the correspondence between the device ID and the number of unread messages based on the saved correspondence between the user ID and the device ID. After obtaining the correspondence between the device ID and the number of unread messages, the number of unread messages can be sent to the corresponding electronic device based on the device ID through the near-field distributed soft bus or Bluetooth communication. The user can be guided to check the content of the Beidou satellite message reply on the logged-in electronic device, and does not need to be always next to the target terminal device, but can move within a certain range of the target terminal device.

[0195] like Fig.11 As shown, Zhang San's smart car 301E receives the member IDs and the number of unread Beidou messages of all members in the group, and displays the nicknames and the number of unread Beidou messages by reading the relationship between the member IDs and the member nicknames stored in the local database of the smart car. In one implementation, because the Changlian server stores the user nicknames, the Beidou message sent to the smart car includes the member nicknames. After receiving the Beidou message carrying the nickname, the smart car 301E does not need to associate the relationship between the member ID and the member nickname, and can display it directly.

[0196] In this example, Zhang San has 5 unread Beidou messages, Xiao Chen has 3 unread Beidou messages, and Xiao Zhao has 2 unread Beidou messages. The smart car saves the device IDs of the group members, and sends the message corresponding to the member ID to the mobile device corresponding to the device ID through the relationship between the member ID and the device ID in the local database and the distributed soft bus. For example, control 1101 represents the unread message content displayed on the mobile phone 301A used by Zhang San, and control 1102 represents the unread message content displayed on the mobile phone 301B used by Xiao Chen.

[0197] Based on the above scenarios D and E, Fig.12 A schematic diagram of a process for receiving a group Beidou satellite message provided in an embodiment of the present application. The process of the method may include the following steps:

[0198] Step S1201: The third terminal device or the fourth terminal device obtains the message content of the user's reply message to the Beidou satellite message.

[0199] The third terminal device can be, for example, Figure 3 The mobile phone 305A shown in the figure can use the Changlian APP to reply to the Beidou satellite message as described in scenario C; for example, the mobile phone B105 can use the Changlian APP to reply to the Beidou satellite message based on the scenario C; Figure 7 The interface process introduced can obtain the message content of the user's reply message to the Beidou satellite. The specific acquisition process can refer to the content introduced in scenario C, which will not be repeated here.

[0200] Step S1202: The third terminal device or the fourth terminal device sends a reply message to the server.

[0201] Exemplarily, mobile phone 305A can send a reply message to a server through a communication network. In this case, the server can be a server corresponding to an instant messaging service, such as a Changlian server corresponding to the Changlian APP. In addition, it can be understood that the server can be a single server or a cluster of multiple servers, which is not limited in this application. It can be understood that the reply message can include a user identifier, such as a user identifier corresponding to mobile phone 301A. The user identifier can include, for example, but is not limited to, a user number, a device number, etc.; wherein, the device number can also be used to implement encryption and decryption of messages, etc.

[0202] Step S1203: the server stores the reply message.

[0203] Among them, the server may include multiple microservices for implementing different functions, and different microservices can be deployed in the same server or in different servers in a server cluster.

[0204] Step S1204: the target terminal device sends a letter query request message to the satellite.

[0205] Specifically, the target terminal device sends a letter query request message to the satellite. It can be understood that the letter query request message carries a group identifier corresponding to the first group.

[0206] Step S1205, the satellite forwards the letter query request message sent by the target terminal device to the server based on the letter query request message sent by the target terminal device. Similarly, the letter query request message sent to the server carries the group identifier corresponding to the first group. It should be noted that the satellite can send a Beidou satellite query group request message to the server through the Beidou satellite ground information processing center.

[0207] Step S1206: The server returns a BeiDou satellite message to the group.

[0208] The server receives a letter query request message from a target device via a satellite, and obtains the group identifier of the first group in the letter query request message. A user identifier list is obtained based on the correspondence between the group identifier stored on the server and the user identifier corresponding to each terminal device in the group. The server traverses the user identifier list, confirms that each user identifier in the user identifier list has at least one satellite message to be received in the server, that is, confirms whether the message mailbox of the group member has a satellite message to be received. If a certain user identifier does not have a corresponding satellite message to be received in the server, the user identifier is deleted from the user identifier list. After traversing the user identifier list, the server returns the user identifier list to the target terminal device, that is, returns the first satellite message to the target terminal device via a satellite, and the first satellite message includes the user identifier list, that is, returns the users in the first group who have satellite messages to be received to the target terminal device.

[0209] In some embodiments, the server may also return the number of unread messages associated with one or more user identifiers in the user identifier list to the target terminal device, that is, the first satellite message contains the corresponding relationship between the user identifier and the number of unread messages, which is used for the target terminal device to display the number of messages to be received corresponding to the to-be-received user. The contents returned to the target terminal device are listed as follows:

[0210] User ID Unread satellite messages Zhang San's User ID 5 Xiaochen's User ID 3 Xiao Zhao's User ID 2

[0211] Furthermore, considering the limitation of satellite message length, in order to store more information in satellite messages, the server can convert the user ID into a user number, where the number of bytes occupied by the user number is smaller than the number of bytes occupied by the user ID. For example, a group can add 32 users, and the user numbers in the group can be arranged from 0 to 31. When a user is added to the group, the server will assign an unused number to the user; when the user exits the group, the user number associated with the user will be set to an idle state, which is convenient for the next user added to the group to use.

[0212] In some embodiments, the server may also return the user nicknames associated with one or more user identifiers in the user identifier list to the target terminal device, that is, the first satellite message includes the correspondence between the user identifier and the user nickname, and the content returned to the target terminal device is listed as follows:

[0213] User ID Unread satellite messages User Nickname Zhang San's User ID 5 Zhang San Xiaochen's User ID 3 Xiao Chen Xiao Zhao's User ID 2 Xiao Zhao

[0214] After receiving the above message format, the target terminal device can directly display the user nickname without querying the local database, which also avoids the problem of not being able to display the user nickname when the local database is abnormally inaccessible.

[0215] Further, the user identifiers in the user identifier list are sorted according to the user identifier that has received the latest satellite message reply. Specifically, the terminal device identified by the user identifier in the user identifier list may have one or more satellites to be received, that is, the user identifier in the user identifier list may correspond to one or more satellites to be received. The server obtains the reply time of the latest satellite message to be received corresponding to each user identifier, and sorts the user identifiers in the user identifier list according to the time, and puts the user identifier that has received the satellite message most recently in front, so that the target terminal device displays the information in the order of the latest satellite message received. For example, the time of the 5 satellite messages to be received received by Zhang San is 12:00, 12:05, 12:10, 12:15, and 12:20 on the same day; the time of the 3 satellite messages to be received received by Xiao Chen is 11:00 and 11:05 respectively; the time of the 3 satellite messages to be received received by Xiao Zhao is 12:30, 12:35, and 12:40 respectively. The server obtains the latest time of the satellite to be received corresponding to each user, that is, the time corresponding to Zhang San is 12:20, the time corresponding to Xiao Chen is 11:05, and the time corresponding to Xiao Zhao is 12:40. After sorting by the latest time, the user IDs in the user ID list will be sorted in the order of Xiao Zhao, Zhang San, and Xiao Chen.

[0216] It is understandable that due to the message length limit of Beidou satellite messages, if the length of the first Beidou message returned exceeds the Beidou satellite message length limit, the server will intercept the content to ensure that the length of the first Beidou message returned does not exceed the message length limit. When the first satellite message returned contains the corresponding relationship between the user ID and the number of unread messages, the server intercepts it according to the "user ID-unread message number" sequence; when the first satellite message returned contains the corresponding relationship between the user ID and the user nickname, the server intercepts it according to the "user ID-user nickname-unread message number" sequence.

[0217] After the server has counted a reply message, it will add a read label according to the group ID, indicating that the reply message has been read in the group and notified the user. Even if the server receives a letter query request message with the same group ID, the tagged reply message will be ignored and not included in the statistics to avoid duplicate statistics and waste of resources. The target terminal device will cache the group Beidou message content and will not affect the user's receipt.

[0218] In some embodiments, when there are fewer group members or the terminal device sending the message in the group cannot view the reply message due to other reasons such as exhausted battery, the server can find at least one user identifier stored in the group based on the received group identifier and the correspondence between the group identifier and the user identifier corresponding to each terminal device in the group, and when the stored reply message is found based on the at least one user identifier, the server returns the specific content of the reply message to the satellite.

[0219] Step S1207: The target terminal device receives the Beidou satellite message returned by the satellite group.

[0220] Specifically, after receiving the group Beidou satellite message returned by the Changlian server, the satellite sends the message to the target terminal device.

[0221] Optionally, the target terminal device may be a smart car or a mobile phone, and the type of the target terminal device is not limited in this application.

[0222] Step 1208: The target terminal device displays that the group Beidou satellite information has been received.

[0223] Specifically, after the target terminal device receives the group Beidou satellite message, it associates the user nickname in the local database of the device according to the user identifier, and displays the user to receive the satellite message on the device. The display content is as follows:

[0224] Users waiting to receive satellite messages: Zhang San, Xiao Chen, Xiao Zhao.

[0225] In some embodiments, the server returns the number of unread messages associated with one or more user identifiers in the user identifier list to the target terminal device. After the target terminal device receives the group Beidou satellite message, it is associated with the user nickname in the local database of the target terminal device according to the user identifier. At this time, the content of the satellite message to be received is displayed on the target terminal device as follows:

[0226] Zhang San: Received 5 unread Beidou messages.

[0227] Xiao Chen: Received 3 unread Beidou messages.

[0228] Xiao Zhao: Received 2 unread Beidou messages.

[0229] In some embodiments, the server also returns the user nicknames associated with one or more user identifiers in the user identifier list to the target terminal device. At this time, the target terminal device does not need to search the local database, and the displayed content is not repeated.

[0230] In one embodiment, if the target terminal device is a smart car, the above information is displayed on the central control screen of the smart cockpit. In addition to displaying information, the smart car can also remind by flashing lights or honking in parking scenarios. For example, if group members are active in a certain range outdoors, they can be quickly notified by flashing lights or honking.

[0231] It should be noted that the above-mentioned scenes A to E are only several possible scenes introduced in the embodiments of the present application. For example, the various scenes can also be combined, and the present application does not limit the specific scenes. For example, although the smart car and smart phone are used as the first electronic device to receive the Beidou message of the group in the above-mentioned scenes, in actual implementation, the first electronic device can also be other smart electronic devices. In addition, the touch operations involved in the above-mentioned scenes can be implemented by but not limited to the following methods: click operation, or double-click operation, or long press operation, or voice command, etc., which can be implemented according to the form of terminal device configuration during specific implementation. In addition, the network connection status involved in the above-mentioned scenes can include cellular networks, Wi-Fi networks, etc.; it can be understood that when there is no network connection state, the terminal device can use the Beidou satellite network for communication.

[0232] Based on the above description of the interface processing effect that can be achieved by the method provided in the embodiment of the present application, the following describes the implementation process of the communication method provided in the present application to illustrate how to use the method provided in the present application to achieve the above-mentioned effect. Figures 4 to 11 The interface processing effect shown, and how to use the method provided by this application to achieve the effects shown in the aforementioned scenes A to E. Thus, the reply to the group Beidou satellite message and the reception of the reply message can be realized, which can meet more satellite communication application scenarios and provide users with better communication guarantee.

[0233] In combination with the above embodiments and related drawings, the present application embodiment provides a communication method.
