[0029] The satellite communication method and system of the present application will be further described in detail below in combination with specific embodiments and drawings.

[0030] The present application provides a satellite communication method, including the following steps S101-S103 or steps S201-S203, different application scenarios may have different requirements for the receiving and sending order of data, the following two embodiments can meet the diversified scene requirements; in some scenarios, it may be necessary to receive the data of the opposite end device first and then send the collected data of the mobile communication end; while in some other scenarios, the user may send a satellite communication request, and the opposite end device may return data.

[0031] Please refer to Figure 1 In a feasible embodiment, Step S101: creating a sub-thread for the corresponding mobile communication end by the vehicle machine end based on the current connected device, and establishing a thread connection by the mobile communication end based on the sub-thread.

[0032] Step S102: after the thread connection is successful, receiving satellite communication data sent by the opposite end device through the vehicle machine end, and sending the satellite communication data to the mobile communication end through the sub-thread.

[0033] Step S103: sending satellite communication data collected by the mobile communication end to the vehicle machine end through the sub-thread, and sending the satellite communication data to the opposite end device through the vehicle machine end, so as to realize satellite communication between the opposite end device and the mobile communication end.

[0034] In this embodiment, it is assumed to be an emergency rescue scene, the opposite end device is a rescue command center, the mobile communication end is a mobile phone end of a user in a vehicle to be rescued, and the vehicle machine end is a vehicle-mounted system of the vehicle to be rescued.

[0035] Specifically, after the vehicle to be rescued starts the satellite communication function, the mobile phone is connected to the vehicle terminal through, for example, WiFi, the vehicle terminal runs a program to create a sub-thread for the mobile phone, the mobile phone receives the relevant information of the sub-thread and calls the network connection module to establish a connection with the vehicle terminal, the vehicle terminal receives the rescue message or rescue call sent by the rescue command center through satellite communication, and then the vehicle terminal sends the data to the mobile phone through the sub-thread, the mobile phone can be used by the user to edit a message or make a call, so as to return the data of the mobile phone to the vehicle terminal through the sub-thread, and then the vehicle terminal sends the data to the rescue command center, thereby realizing the satellite communication between the rescue command center and the mobile phone.

[0036] See Figure 2 In another possible embodiment, Step S201: creating a sub-thread for a corresponding mobile communication terminal based on a currently connected device through a vehicle terminal, and establishing a thread connection based on the sub-thread through the mobile communication terminal.

[0037] Step S202: sending satellite communication data collected by the mobile communication terminal to the vehicle terminal through the sub-thread, and sending the satellite communication data to a peer device through the vehicle terminal after the thread connection is successful.

[0038] Step S203: receiving satellite communication data sent by the peer device through the vehicle terminal, and sending the satellite communication data to the mobile communication terminal through the sub-thread, so as to realize satellite communication between the peer device and the mobile communication terminal.

[0039] In this embodiment, it is assumed that it is a self-driving tour scene, the peer device is a tourist service center of a scenic spot, the mobile communication terminal is a smart phone carried by a tourist, and the vehicle terminal is a vehicle-mounted system of a vehicle driven by the tourist; the tourist needs to feed back information such as a vehicle position and a state of people in the vehicle to the tourist service center of the scenic spot in real time during the self-driving tour, and receives information such as road conditions and opening conditions of scenic spots provided by the service center of the scenic spot.

[0040] Specifically, when the tourist starts the vehicle, the vehicle terminal detects that the smart phone of the tourist is successfully connected through, for example, WiFi, the system program of the vehicle terminal creates a sub-thread for the smart phone, the smart phone receives the relevant information of the sub-thread sent by the vehicle terminal, calls the network connection management module, and establishes a thread connection with the vehicle terminal based on the sub-thread; after the thread connection is successful, the smart phone collects satellite positioning data of the vehicle by using the built-in GPS module, and the tourist can input information such as a health state of people in the vehicle and whether help is needed through an application program on the mobile phone, or make a call; the smart phone sends the collected satellite communication data to the vehicle terminal through the sub-thread, and the vehicle terminal receives the data and sends the data to the tourist service center of the scenic spot through the satellite communication module of the vehicle.

[0041] Further, after the scenic spot visitor service center receives the information sent by the visitor vehicle, according to the information and real-time conditions in the scenic spot, the relevant feedback information such as the congestion of the front road, the real-time passenger flow of a scenic spot, whether there is an emergency notice, and satellite communication data are generated, and these data are sent to the vehicle terminal through the satellite communication network. The vehicle terminal sends these data to the smart phone through the previously established sub-thread. After the smart phone receives the data, it is displayed on the screen in an intuitive way, such as marking the congested section on the map, and prompting the opening of the scenic spot in the text, so that the visitors can timely understand the relevant information, and realize the satellite communication between the scenic spot visitor service center and the smart phone.

[0042] The creation of the sub-thread includes: connecting the vehicle terminal and the mobile communication terminal based on wireless technology; creating a listening thread through the vehicle terminal, and binding the listening thread to the target server terminal, and creating a corresponding sub-thread in the listening thread for the mobile communication terminal successfully connected by wireless.

[0043] In some embodiments, the wireless technology is preferably WiFi technology; the vehicle terminal is started, and the satellite communication module and the WiFi module of the vehicle terminal are also started, and the mobile communication terminal is also started. The vehicle terminal calls the configuration and opening AP interface provided by the WiFiManager of the Android system; then the mobile communication terminal (such as a mobile phone or other mobile communication devices supporting wireless technology and communication functions) searches for the vehicle terminal AP (Access Point, wireless access point) by calling the WiFi function provided by the system, and connects with the vehicle terminal AP.

[0044] Further, the vehicle terminal creates a ServerSocket listening thread, which is an independent thread at this time to prevent blocking the main process; at the same time, the target server terminal is initialized to bind the corresponding IP and port to be in a continuous listening state; then the vehicle terminal starts a sub-thread for each mobile communication terminal Socket, and realizes the sending and receiving of messages through InputStream and OutputStream, avoiding the problem of single-thread blocking.

[0045] In the above technical solution, the communication device is usually equipped with wireless communication function, which can connect the vehicle terminal and the mobile communication terminal without increasing the hardware cost, improving the universality and compatibility of the application; by binding the server, the stable communication between the vehicle terminal and the server is ensured; and a sub-thread is created for each mobile communication terminal, which realizes multi-user concurrent processing, so that multiple mobile communication terminals can communicate with the vehicle terminal.

[0046] Further, the thread connection establishment includes: initiating a thread connection request through the target server end in the corresponding sub-thread through the mobile communication end, and returning a connection success signal to the mobile communication end through the target server end after the thread connection is successful.

[0047] In some embodiments, the mobile communication end initiates a connection request by specifying a server IP and a port through a Socket class in a sub-thread, and waits for a Socket server message after the connection is successful.

[0048] In the above technical solution, the response of the target server end to the connection request ensures the security of the connection and provides a basis for subsequent satellite communication.

[0049] Further, the satellite communication data at least includes first satellite communication data; and the sending of the satellite communication data to the mobile communication end through the sub-thread includes: receiving first satellite communication data sent by a peer device through the vehicle machine end, and encapsulating the first satellite communication data through a corresponding communication protocol; wherein the first satellite communication data at least includes first satellite short message data or first satellite call audio data.

[0050] When the first satellite communication data is first satellite short message data, the sub-thread is traversed to send the encapsulated first satellite short message data to the mobile communication end through the sub-thread.

[0051] In some embodiments, when the vehicle machine end receives satellite short messages (i.e., the first satellite short message data), the satellite short messages are encapsulated through the communication protocol in Table 1, and the satellite short messages are sent to each mobile communication end through the sub-thread in the Socket list by calling OutputStream, realizing one-to-many communication.

[0052] Table 1 is as follows:

[0053] When the first satellite communication data is first satellite call audio data, the encapsulated first satellite call audio data is sent to the corresponding mobile communication end through the corresponding sub-thread based on a preset protocol.

[0054] In some embodiments, when the user turns on the satellite phone, the satellite phone audio is given to the car machine end by the satellite communication module through PCM (Pulse Code Modulation), and the car machine end encodes the audio data (i.e. the first satellite call audio data) through Opus in a sub-thread, encapsulates the data through the RTP (Real-Time Transport Protocol) protocol, and sends the audio data to the mobile communication end using the UDP (User Datagram Protocol) + RTP network transmission protocol.

[0055] Wherein, Opus is a lossy audio encoding format that can provide clear and smooth audio experience; RTP is a real-time transport protocol; UDP is a connectionless transport layer protocol; UDP + RTP means encapsulating RTP protocol in UDP data packet for transmission, which utilizes the low delay characteristics of UDP to meet the timeliness requirements of real-time data transmission.

[0056] Further, the first satellite communication data is received by the mobile communication end to analyze the first satellite communication data through the corresponding communication protocol, and to display the analyzed first satellite communication data.

[0057] Wherein, when the first satellite communication data is the first satellite short message data, the mobile communication end receives the satellite short message from the car machine end through the InputStream of Socket, analyzes the satellite short message from the car machine end according to the communication protocol in Table 1, and displays it to the user through the screen.

[0058] When the first satellite communication data is the first satellite call audio data, the mobile communication end receives Socket data in a sub-thread, decodes the data through Opus, and plays the decoded audio data, so that the user can hear the voice of the opposite end of the satellite phone on the mobile communication end.

[0059] In the above technical solution, using a communication protocol to encapsulate data can standardize the format and transmission method of data, improve the accuracy and stability of data transmission; different sending methods are used for different types of satellite communication data, which can better meet the characteristics and transmission requirements of data; the mobile communication end can analyze and display the received data, so that the user can intuitively obtain satellite communication information.

[0060] Further, the satellite communication data further includes at least second satellite communication data; the satellite communication data is sent to the opposite end device through the car machine end, including: encapsulating the second satellite communication data collected by the mobile communication end through the communication protocol; wherein the second satellite communication data includes at least second satellite short message data or second satellite call audio data.

[0061] When the second satellite communication data is second satellite SMS data, the encapsulated second satellite SMS data is sent to the vehicle terminal through a corresponding sub-thread.

[0062] In some embodiments, the mobile communication terminal receives a satellite SMS edited by a user (i.e., the second satellite SMS data), encapsulates the satellite SMS through the communication protocol in Table 1, and sends the encapsulated data to the vehicle terminal through the OutputStream of a Socket.

[0063] When the second satellite communication data is second satellite call audio data, the encapsulated second satellite call audio data is sent to the vehicle terminal based on a preset protocol through a corresponding sub-thread.

[0064] In some embodiments, when the user speaks, the mobile communication terminal collects microphone data of the mobile communication terminal in a sub-thread, encodes the collected audio data (i.e., the second satellite call audio data) through Opus, encapsulates the data through the RTP protocol, and sends the audio data to the vehicle terminal using the network transmission protocol of UDP+RTP.

[0065] Further, the second satellite communication data is received by the vehicle terminal to parse the second satellite communication data through a corresponding communication protocol, and the parsed second satellite communication data is sent to a peer device.

[0066] When the second satellite communication data is second satellite SMS data, the vehicle terminal receives data from the mobile communication terminal through the InputStream of a Socket, parses the satellite SMS from the mobile communication terminal through the communication protocol in Table 1, and sends the SMS content through a satellite communication module. When multiple mobile communication terminals send SMS, the vehicle terminal sends satellite SMS according to the order of receipt.

[0067] When the second satellite communication data is second satellite call audio data, the vehicle terminal receives Socket data in a sub-thread, decodes the data through Opus, and sends the decoded audio data to the peer through a satellite communication module. The user at the peer can hear the user's voice.

[0068] In the above technical solution, similar to the encapsulation when receiving data, the data collected by the mobile communication terminal is encapsulated to ensure the standardization and accuracy of the data in the transmission process, facilitating the processing of the vehicle terminal and the peer device; different sending methods are used according to the data type to ensure efficient transmission of different types of data; the vehicle terminal parses the received data before sending it to the peer device, ensuring the accuracy and consistency of the data.

[0069] It should be noted that the terms "first satellite communication data," "second satellite communication data," "first satellite SMS data," "second satellite SMS data," "first satellite call audio data," and "second satellite call audio data" are merely used to distinguish different data senders; "first" and "second" have no additional meaning.

[0070] Furthermore, the implementation of satellite communication between the peer device and the mobile communication terminal also includes: obtaining the satellite phone status in real time through the vehicle terminal, encapsulating the satellite phone status through the satellite phone status protocol, and traversing sub-threads to send the encapsulated satellite phone status to the corresponding mobile communication terminal through the sub-threads; receiving the satellite phone status through the mobile communication terminal, parsing the satellite phone status through the satellite phone status protocol, and displaying the parsed satellite phone status through the mobile communication interface.

[0071] In some embodiments, when the satellite phone status changes, such as from idle to incoming call, from incoming call to connected, or from connected to disconnected, the vehicle terminal encapsulates the satellite phone status according to the satellite phone status protocol in Table 2, and traverses the Socket list to send it to the mobile communication terminal via Socket. The mobile communication terminal parses the data according to the satellite phone status protocol in Table 2 and displays it to the user according to the satellite phone status.

[0072] Table 2 is shown below:

[0073] In the above technical solution, the satellite phone status is acquired in real time and synchronized to the mobile communication terminal, allowing users to understand the usage status of the satellite phone at any time, such as whether there are incoming calls or whether it is in a call; the use of the satellite phone status protocol ensures the accurate transmission of status information, and the traversal of sub-threads ensures that all connected mobile communication terminals can obtain status information in a timely manner; the mobile communication terminal can parse and display the satellite phone status, allowing users to intuitively understand the current status of the satellite phone and providing a basis for user operation.

[0074] Furthermore, the implementation of satellite communication between the peer device and the mobile communication terminal also includes: encapsulating the operation data of the mobile communication terminal through a satellite phone operation protocol, and sending the encapsulated operation data to the vehicle terminal through a corresponding sub-thread; wherein, the operation data includes at least hang-up data, answer data, or dial data; the vehicle terminal receives the operation data in the order of operation, parses the operation data through the satellite phone operation protocol, and feeds the operation data back to the peer device, while updating the satellite phone status in real time based on the operation data.

[0075] In some embodiments, when a satellite phone call comes, the mobile communication terminal notifies the incoming call interface, the user selects the hang up or answer satellite phone operation, the mobile communication terminal encapsulates the hang up or answer operation according to the satellite phone operation protocol in Table 3, and sends it to the vehicle terminal through Socket, the vehicle terminal parses the data according to the satellite phone operation protocol in Table 3, and performs corresponding operations on the satellite communication module according to the user hang up or answer operation. The vehicle terminal first responds to the mobile phone terminal command of the first operation, and updates the satellite phone state in time.

[0076] The user inputs the mobile phone number of the opposite terminal through the mobile communication terminal and dials, the mobile communication terminal encapsulates the dialing data according to the satellite phone operation protocol in Table 3, and sends it to the vehicle terminal through Socket, the vehicle terminal parses the data according to the satellite phone operation protocol in Table 3, and performs satellite phone dialing operation on the satellite communication module according to the user dialing operation. The vehicle terminal first responds to the command of the mobile communication terminal of the first operation, and updates the satellite phone state in time. The satellite phone call and incoming call state do not allow dialing of the satellite phone.

[0077] Table 3 is as follows:

[0078] In the above technical solution, the operation data of the mobile communication terminal is encapsulated, which ensures the integrity and accuracy of the operation data in the transmission process; the satellite phone operation protocol specifies the format of the operation data, which facilitates the analysis and processing of the vehicle terminal; the vehicle terminal receives and analyzes the operation data according to the operation sequence, which ensures the accuracy and timeliness of the operation; the satellite phone state is updated in real time, which ensures the real-time and accuracy of the state information.

[0079] Further, the satellite communication between the opposite terminal device and the mobile communication terminal is implemented, which further comprises: disconnecting the thread connection and the wireless connection through the vehicle terminal, and disconnecting the thread connection through the mobile communication terminal.

[0080] In some embodiments, the user disconnects the satellite communication function sharing through the vehicle terminal interface, the vehicle terminal disconnects the Socket connection, resets the related configuration, and closes the AP function. The mobile communication terminal disconnects the Socket connection and resets the related configuration.

[0081] In the above technical solution, when the satellite communication function is not needed, disconnecting the connection in time can save device resources and avoid unnecessary communication interference; the vehicle terminal and the mobile communication terminal disconnect the connection at the same time, which ensures the complete disconnection of the connection and improves the safety and stability of the system.

[0082] In summary, the satellite communication method makes the user carry the mobile communication terminal (such as a mobile phone) to leave the vehicle for a certain distance to realize satellite communication, and breaks the limitation that the satellite communication function must be used in the vehicle, thereby expanding the range of use of the satellite communication function by the user; meanwhile, the satellite communication function can be used by multiple users.
