[0047] The following, in conjunction with the accompanying drawings, describes in detail the communication control method, apparatus, terminal device, and medium of the dual-mode satellite communication terminal device provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0048] Example 1

[0049] Figure 1 FIG. 1 is a flow chart of a communication control method for a dual-mode satellite communication terminal device provided in Example 1 of the present application. Figure 1 As shown, the specific steps include:

[0050] S101, obtaining connection monitoring information of a terminal device in a first satellite communication mode, wherein the connection monitoring information includes one or more of: satellite pairing duration and number information, satellite call channel allocation feedback information, satellite call connection status information, and satellite call quality information;

[0051] First, this application is applicable to scenarios where terminal devices are used for satellite communications. The terminal devices of this solution include, but are not limited to, smart terminals and satellite communication terminals. The terminal devices also have dual-mode satellite communication capabilities, meaning they can communicate with two different satellite systems. Based on the above usage scenarios, it is understandable that the execution entity of this application can be a terminal device.

[0052] Terminal equipment can be any device with satellite communication capabilities, such as satellite phones, satellite positioning devices, smart terminals, etc. It is the main body of the entire communication process and is used to achieve communication interaction with satellites.

[0053] The first satellite communication mode may be a specific satellite communication mode, such as the Tiantong satellite communication mode, which specifies technical parameters such as the communication protocol, frequency range, and signal modulation method between the terminal device and the satellite.

[0054] Connection monitoring information can be a series of information used to reflect the connection status and communication quality between the terminal device and the satellite. Specifically, it may include but is not limited to the following information:

[0055] Information on the duration and number of satellite alignments. The duration refers to the time it takes a terminal device to search for satellite signals and establish a connection with a satellite. For example, how long does it take for a terminal device to point in a certain direction of the sky to search for a satellite signal and establish a connection? This duration is considered the alignment duration and can be recorded by the terminal device's internal high-precision clock module. The number of alignments refers to the cumulative number of successful satellite connections established by the terminal device. This information helps understand the frequency and stability of communication between the terminal device and the satellite.

[0056] Satellite communication channel allocation feedback information is the information returned by the satellite after allocating a communication channel to a terminal device, including whether the channel was successfully allocated, the allocated channel number, the channel bandwidth, and the duration of availability. This information is crucial for the terminal device to understand its resource usage in the satellite communication network.

[0057] The satellite call connection status information may describe the current status of the satellite call connection, such as connection successful, connection failed, connection interrupted, and connection waiting, etc. By monitoring the connection status information, problems that occur during the call can be discovered in a timely manner.

[0058] Satellite call quality information measures satellite call quality, including signal-to-noise ratio, bit error rate, and packet loss rate. This information is obtained using advanced audio signal processing algorithms and signal analysis techniques, accurately reflecting call clarity and stability.

[0059] In this solution, the terminal device collects and parses relevant connection monitoring information from the satellite communication link through its built-in communication module in accordance with the protocol and signal processing mechanism of the first satellite communication mode.

[0060] S102, switching the satellite communication mode of the terminal device from the first satellite communication mode to the second satellite communication mode if the connection monitoring information meets a set condition;

[0061] The conditions can be pre-defined rules or thresholds based on different application scenarios and communication requirements. For example, a condition is met when the number of satellite call connection failures exceeds a certain number, such as five, or when the bit error rate in satellite call quality information exceeds a certain threshold, such as 1%. These conditions are dynamically adjustable and can be optimized based on actual conditions.

[0062] The second satellite communication mode may be another satellite communication mode different from the first satellite communication mode, for example, it may be a Beidou satellite communication mode, etc., having different communication protocols, signal characteristics and network architecture.

[0063] Based on the comparison of connection monitoring information with pre-set conditions, the terminal device can switch from the first satellite communication mode to the second satellite communication mode if the pre-set conditions are met, indicating that the connection in the first satellite communication mode is unstable or unavailable. During the switching process, intelligent algorithms can be used to optimize the switching process to minimize the switching time and impact on communications, and improve the switching speed. For example, important data can be cached in advance to ensure a fast switching process.

[0064] S103, sending a short message to a target satellite in a second satellite communication mode, wherein the short message includes status information and connection monitoring information of the terminal device;

[0065] The target satellite of the second satellite communication mode may be a specific satellite with which the terminal device communicates in the second satellite communication mode. The target satellite is selected based on communication requirements and satellite network scheduling.

[0066] Short message is a message with relatively small data volume and concise format, which is used to transmit key information in satellite communications.

[0067] The status information of terminal devices can reflect the working status of the terminal devices themselves, such as device power, storage capacity, and software version. By monitoring this information in real time, we can understand the operation of the device and provide a basis for device management and maintenance.

[0068] The terminal device encodes the short message containing status information and connection monitoring information and sends it to the target satellite through a wireless signal in accordance with the communication protocol and signal transmission mechanism of the second satellite communication mode.

[0069] In this solution, the connection monitoring information in the first satellite communication mode is also sent to the target satellite, so that the target satellite can understand the urgency of the current satellite connection and the previous data, which can facilitate the target satellite to determine the priority of the current satellite connection, thereby achieving rapid access and providing satellite communication services to users.

[0070] This solution sends short messages containing terminal device status information and connection monitoring information to the target satellite, allowing the satellite to grasp the status of the terminal device in real time, facilitating resource scheduling and management of the satellite network, and also providing important data reference for subsequent communication mode switching and optimization.

[0071] S104 , monitoring satellite status information of the first satellite communication mode in real time in the second satellite communication mode, and switching the satellite communication mode of the terminal device to the first satellite communication mode when the satellite status information meets a preset standard.

[0072] The second satellite communication mode may refer to the working state of the second satellite communication mode currently being adopted by the terminal device, including the execution of the communication protocol, reception and transmission of signals, etc.

[0073] The satellite status information of the first satellite communication mode may be information reflecting the operating status and communication capability of the satellite in the first satellite communication mode, such as the satellite's signal strength, channel availability, and load. This solution may obtain this information through signal monitoring technology and data analysis algorithms.

[0074] The preset criteria may be pre-set conditions and thresholds for determining whether to switch back to the first satellite communication mode. For example, when the satellite signal strength of the first satellite communication mode reaches a certain strength and the channel availability is good, the preset criteria are met.

[0075] The terminal device utilizes a built-in signal monitoring module to collect, in real time, signals transmitted by satellites in the first satellite communication mode, analyze and process the signals, and extract satellite status information. An intelligent monitoring algorithm dynamically adjusts monitoring parameters based on different communication environments and requirements, improving monitoring accuracy and timeliness. When the monitored satellite status information in the first satellite communication mode meets preset criteria, the terminal device switches the communication mode from the second satellite communication mode back to the first satellite communication mode through signaling interaction with the satellite and parameter adjustments. Intelligent algorithms are also used to optimize the handover process, ensuring stability and efficiency.

[0076] In the second satellite communication mode, the satellite status information of the first satellite communication mode is monitored in real time, and when the preset standards are met, it switches back to the first satellite communication mode, realizing dynamic switching between the two communication modes, enabling the terminal device to select the optimal communication mode according to the satellite status and communication needs, improving the flexibility of satellite communication and enhancing the user's communication experience.

[0077] In an embodiment of the present application, by controlling the communication of the dual-mode satellite communication terminal device, a reasonable choice can be made according to the real-time status of the two modes of satellite communication, thereby ensuring a stable connection of the satellite communication, ensuring the accurate sending and receiving of information in the required scenarios, and providing protection for the satellite communication of the terminal device. At the same time, it can also avoid the problem of rapid power consumption of the terminal device due to multiple connections for a long time or the inability to conduct effective satellite calls, or even the inability to communicate effectively until the power is out.

[0078] In one embodiment, optionally, the first satellite communication mode is a Tiantong satellite call mode;

[0079] The second satellite communication mode is the Beidou short message communication mode.

[0080] The Tiantong satellite communication mode is enabled by the Tiantong satellite system. The Tiantong satellite system is a vast satellite communications network consisting of multiple geosynchronous orbit satellites and several medium-orbit satellites, designed to provide high-quality voice communication services to users worldwide. The Tiantong satellite communication mode uses specific frequency bands for signal transmission and generally employs modulation and demodulation technologies such as Quadrature Phase Shift Keying (QPSK) and 16-Quadrature Amplitude Modulation (16QAM) to improve signal transmission efficiency and interference resistance. The Tiantong satellite communication mode ensures stable and reliable voice calls and supports a variety of communication functions, such as standard voice calls and emergency calls. Furthermore, to adapt to different application scenarios, the Tiantong satellite communication mode also incorporates encryption mechanisms to ensure the security of communication content.

[0081] The Beidou short message communication mode is a unique feature of the Beidou satellite navigation system. In addition to providing high-precision positioning and navigation services, the Beidou satellite navigation system also features short message communication, enabling the transmission of short messages between terminals or between terminals and ground control centers. This mode leverages the coverage of the Beidou satellite constellation to enable communication globally or within specific regions. Its communication frequency bands are specialized to meet communication needs in diverse environments. During communication, the terminal device encapsulates the information to be transmitted into a short message according to a specific format and forwards it via satellite to the target terminal or ground control center. Short messages are subject to certain restrictions on length and format, but can typically contain text, numbers, and simple commands. The Beidou short message communication mode has significant application value in remote areas, offshore areas, mountainous areas, and other areas with weak communication infrastructure, providing users with a reliable communication method.

[0082] The satellite communication channels mentioned above are the communication channels allocated by the satellite to terminal devices for voice calls in the Tiantong satellite communication mode. Each channel has a specific frequency range and bandwidth, and different terminal devices communicate through their assigned channels to avoid mutual interference. Satellite communication channel allocation is determined based on the terminal device's request and the satellite network's resource availability. The satellite allocates available channels to the appropriate terminal device based on specific algorithms and strategies to ensure communication quality and efficiency. The channel bandwidth affects the quality of voice calls. The larger the bandwidth, the more voice data can be transmitted, resulting in better call quality.

[0083] This technical solution, through the rational use of Tiantong satellite call mode and Beidou short message communication mode, as well as intelligent switching between modes, combined with the accurate acquisition, transmission, and monitoring of various types of information, enables terminal devices to flexibly select the optimal communication mode for different communication environments and needs. This not only improves communication stability and ensures the quality of voice calls and information transmission, but also fully utilizes the advantages of both satellite communication modes, expands communication coverage and application scenarios, and provides users with more efficient, convenient, and secure communication services.

[0084] In one embodiment, optionally, monitoring satellite status information of the first satellite communication mode in real time in the second satellite communication mode, and switching the satellite communication mode of the terminal device to the first satellite communication mode when the satellite status information meets a preset standard, includes:

[0085] In the second satellite communication mode, requesting the satellite signal strength and / or satellite channel usage status corresponding to the first satellite communication mode through the monitoring module;

[0086] When the satellite signal strength meets a first preset standard, switching the satellite communication mode of the terminal device to a first satellite communication mode;

[0087] and / or,

[0088] When the satellite channel usage status meets a second preset standard, the satellite communication mode of the terminal device is switched to the first satellite communication mode.

[0089] The monitoring module is a combination of hardware and software within the terminal device specifically designed to monitor satellite communication mode information in real time. The hardware may include a highly sensitive signal receiving antenna, signal amplifier, and filters to capture and process satellite signals. The software, including signal analysis algorithms and data processing programs, parses the received signals and extracts key information such as satellite signal strength and satellite channel usage status. The monitoring module must offer high accuracy, reliability, and low power consumption to ensure continuous and stable operation without impacting other terminal device functions.

[0090] Satellite signal strength refers to the power of the satellite's transmitted signal when it reaches the terminal device, typically measured in decibel milliwatts (dBm). Signal strength is a key indicator of the quality of the communication link between the satellite and the terminal device. Generally speaking, higher signal strength reduces interference and attenuation during signal transmission, resulting in better communication quality, such as higher data rates and clearer voice calls. However, when signal strength falls below a certain threshold, it may lead to unstable communication connections, data loss, or degraded call quality.

[0091] Satellite channel usage status primarily describes the occupancy and availability of satellite channels. It includes information such as the number of channels occupied by terminal devices, channel busyness, and the number and distribution of remaining available channels. Satellite channel usage status is crucial for terminal devices to decide whether to switch back to the primary satellite communication mode. If channel resources are limited, even with sufficient satellite signal strength, good communication quality may not be guaranteed. In this case, the terminal device may choose to continue in the current Beidou short message communication mode.

[0092] The first preset criterion is a pre-set threshold or condition for satellite signal strength, used to determine whether the requirements for switching the terminal device's satellite communication mode back to Tiantong satellite call mode are met. This criterion is determined based on factors such as actual communication needs, satellite system performance, and terminal device characteristics. For example, the first preset criterion may be met when the satellite signal strength reaches or exceeds -80dBm and persists for a certain period of time, such as 5 minutes. Proper setting of the first preset criterion ensures that mode switching occurs when signal quality is sufficiently good, resulting in a better communication experience.

[0093] The second preset criterion is a specific condition or threshold set for the satellite channel usage status, used to determine whether it is appropriate to switch the terminal device's satellite communication mode back to the first satellite communication mode. This may involve limiting channel busyness. For example, the second preset criterion is considered met when the number of occupied channels is less than a certain percentage of the total number of channels, such as 70%, or when the number of remaining available channels meets a certain number, such as at least 5. The establishment of this second preset criterion helps to perform mode switching when satellite channel resources are sufficient, ensuring stable communication services after the switch.

[0094] In this solution, in the second satellite communication mode, the terminal device's monitoring module continuously receives and analyzes signals transmitted by satellites corresponding to the first satellite communication mode. The monitoring process includes real-time signal acquisition and filtering, amplification, and demodulation of the acquired signals using signal processing algorithms to extract key information such as satellite signal strength and satellite channel usage status. The satellite signals corresponding to the first satellite communication mode are analyzed and processed to determine information such as satellite signal strength and satellite channel usage status. Specifically, the monitoring module performs spectrum analysis and power detection on the received satellite signals to extract relevant information. For example, satellite signal strength is determined by analyzing the signal power, and satellite channel usage status is determined by monitoring signaling data in the signals. When the satellite signal strength meets a first preset standard or the satellite channel usage status meets a second preset standard, the terminal device initiates a transition from the second satellite communication mode to the first satellite communication mode. For example, the terminal device, in accordance with the Beidou short message communication mode protocol, terminates the current short message communication task and releases Beidou satellite-related communication resources, such as channel connections and buffer space. The terminal device then activates the Tiantong satellite communication module and performs initial configuration, including searching for Tiantong satellite signals, synchronizing with the satellite, and performing identity authentication. After verifying the terminal device's identity, the Tiantong satellite allocates appropriate communication resources, such as a satellite call channel. Finally, the terminal device adjusts its communication parameters, such as transmit power and modulation, to accommodate the Tiantong satellite call mode, completing the mode switch. To ensure communication continuity during the switch, the terminal device may employ data caching and recovery techniques to ensure that important data and communication status are not lost during the mode switch.

[0095] This solution monitors satellite status information in real time during the first satellite communication mode while in the second satellite communication mode, switching modes based on preset criteria. This allows terminal devices to intelligently select the optimal communication mode based on actual conditions such as satellite signal strength and channel usage. This effectively improves the flexibility and adaptability of the communication system, avoiding communication interruptions or degradation caused by blindly switching modes when inappropriate conditions. It also fully leverages the advantages of different satellite communication modes, ensuring stable and efficient communication and providing users with more reliable communication services.

[0096] In one embodiment, optionally, the first preset standard is that the signal strength is greater than a set signal strength threshold for a continuous preset time period;

[0097] The second preset standard is that the satellite channel usage status is in an allocable channel status.

[0098] The signal strength threshold can be a specific signal strength value determined based on actual communication needs and satellite system performance, usually in decibel milliwatts (dBm). It can be used as one of the criteria for determining whether the satellite signal strength meets the switching conditions. For example, the signal strength threshold may be set to -90dBm. Only when the satellite signal strength remains greater than -90dBm for a preset period of time does it meet the signal strength requirement for switching back to the first satellite communication mode. The setting of this threshold directly affects the timing of mode switching and communication quality. A threshold that is too high or too low may lead to unreasonable mode switching, affecting the user's communication experience.

[0099] An allocatable channel, which can be in the first satellite communication mode, refers to a satellite communication channel in the current satellite system that is unoccupied or can be reallocated to a terminal device for use. The satellite system manages and allocates channel resources. When a terminal device requests communication, it selects a suitable channel from the allocatable channels and allocates it to the device. The status of an allocatable channel includes information such as the channel's idle state, the channel's available bandwidth, and the channel's signal quality. For example, when there are multiple unused channels in the satellite system, and indicators such as the bandwidth and signal quality of these channels meet certain requirements, these channels are considered to be in an allocatable channel state. At this time, if the satellite channel usage status meets a second preset standard, the terminal device can switch back to the first satellite communication mode and obtain the corresponding channel resources.

[0100] This solution clarifies the duration and specific thresholds that the signal strength must meet in the first preset standard, as well as the allocable channel status of the satellite channel usage status in the second preset standard, so that the terminal device has a clearer and more specific basis when judging whether to switch from the second satellite communication mode back to the first satellite communication mode. This precise standard setting can effectively avoid unreasonable mode switching caused by vague standards and improve the accuracy of mode switching. By intelligently switching according to the stability of satellite signal strength and the availability of channel resources, it can ensure that the terminal device switches to the Tiantong satellite call mode at the appropriate time, fully utilizing its voice call advantages while ensuring the stability and quality of communication and enhancing the user's communication experience. In addition, reasonable standard setting can also help optimize the resource allocation of the satellite system and improve the operating efficiency of the entire communication system.

[0101] In one embodiment, optionally, after sending the short message to the target satellite in the second satellite communication mode, the method further includes:

[0102] Performing message identification on the sent short message to determine the satellite communication scenario of the terminal device;

[0103] If it is a daily communication scenario, switching identification is performed based on preset standards;

[0104] If it is an emergency communication scenario, the switching identification is performed according to the preset emergency communication recovery standard;

[0105] Accordingly, when the satellite status information meets a preset standard, switching the satellite communication mode of the terminal device to the first satellite communication mode includes:

[0106] In an emergency communication scenario, when the satellite status information meets a preset emergency communication recovery standard, the satellite communication mode of the terminal device is switched to the first satellite communication mode.

[0107] Message recognition can be the process of analyzing, understanding, and classifying the content of sent short messages. Using technologies like natural language processing and keyword matching, the text, numbers, and other information within short messages are analyzed to determine the communication scenario they represent. For example, if a message contains keywords like "daily report" or "normal communication," it may be identified as a daily communication scenario; if it contains words like "help" or "emergency," it may be identified as an emergency communication scenario.

[0108] Satellite communication scenarios can be used to describe the specific situations and requirements faced by terminal devices during satellite communications. Common scenarios include daily communication and emergency communication. Daily communication scenarios cover general communication activities such as regular voice calls, text messages, and data transmission. Emergency communication scenarios address communication needs during emergencies such as natural disasters and accident rescue operations, where timely communication is extremely important.

[0109] Preset emergency communication restoration criteria can be special handover criteria specifically developed for emergency communication scenarios. Compared to the preset criteria, these criteria are more stringent to ensure rapid and reliable communication restoration in an emergency. For example, they can require that the satellite signal strength is greater than -80dBm for two consecutive minutes and that there are at least five allocable channels. Furthermore, they can have higher requirements for signal stability and communication latency.

[0110] Emergency communications scenarios, specifically satellite communications in the face of emergencies or emergencies, such as earthquakes, fires, and distress at sea, are crucial for ensuring the timeliness and reliability of communications and the effectiveness of rescue operations. In these scenarios, ensuring smooth communication and quickly restoring effective connections are paramount.

[0111] In an emergency communication scenario, the preset standard can be lowered to complete the switching to the first satellite communication mode whenever possible, so as to provide the most efficient communication method and ensure the timeliness of emergency communication.

[0112] This technical solution can adopt different switching standards based on different communication scenarios, significantly improving the flexibility and adaptability of satellite communication systems. In daily communication scenarios, switching identification based on preset standards can rationally optimize the allocation of satellite resources while ensuring communication quality, avoid unnecessary mode switching, and reduce system energy consumption. In emergency communication scenarios, the setting of preset emergency communication recovery standards ensures that communication can be quickly restored at critical moments, greatly improving the ability to rescue and respond to emergencies, and enhancing the practicality of the entire satellite communication system.

[0113] Example 2

[0114] Figure 2 It is a flow chart of the communication control method of the dual-mode satellite communication terminal device provided in the second embodiment of the present application. This solution makes a better improvement to the above embodiment, and the specific improvement is: after the satellite communication mode of the terminal device is switched from the first satellite communication mode to the second satellite communication mode, the method further includes: identifying the movement information of the terminal device; analyzing the movement information using a time series analysis algorithm to obtain a movement prediction result; accordingly, when the satellite status information meets the preset standard, the satellite communication mode of the terminal device is switched to the first satellite communication mode, including: when the satellite status information meets the preset standard, and when the movement prediction result meets the movement restriction condition of the first satellite communication mode, the satellite communication mode of the terminal device is switched to the first satellite communication mode. As Figure 2 As shown, the specific steps include:

[0115] S201, obtaining connection monitoring information of a terminal device in a first satellite communication mode, wherein the connection monitoring information includes one or more of: satellite pairing duration and number information, satellite call channel allocation feedback information, satellite call connection status information, and satellite call quality information;

[0116] S202, switching the satellite communication mode of the terminal device from the first satellite communication mode to the second satellite communication mode if the connection monitoring information meets a set condition;

[0117] S203, sending a short message to a target satellite in a second satellite communication mode, wherein the short message includes status information and connection monitoring information of the terminal device;

[0118] S204, identifying the mobile information of the terminal device;

[0119] Motion information refers to data related to the movement of a terminal device in space. It encompasses multiple dimensions, such as the device's real-time location, including latitude, longitude, and altitude, which can be obtained through the terminal's built-in satellite positioning module. This solution calculates the change in position over time to derive movement speed information. It can also determine the terminal device's heading based on the changing position trend and determine the direction of movement. Furthermore, it can include acceleration information, which, when combined, comprehensively describes the device's movement status.

[0120] S205, analyzing the movement information using a time series analysis algorithm to obtain a movement prediction result;

[0121] Time series analysis algorithms are mathematical algorithms used to process chronologically ordered data sequences and can be used to analyze the movement information of terminal devices. Common time series analysis algorithms include autoregressive models, moving average models, autoregressive moving average models, and more complex methods such as seasonal decomposition and trend analysis. These algorithms can be used to uncover underlying patterns in movement information and predict future movement trends of terminal devices.

[0122] Motion prediction results can be estimates of the terminal device's future movement state, derived by analyzing movement information using a time series analysis algorithm. Specifically, the predictions can include information such as the predicted future location, speed trends, and changes in movement direction. For example, a terminal device is predicted to move northeast within the next 30 minutes.

[0123] S206, monitoring satellite status information of the first satellite communication mode in real time in the second satellite communication mode;

[0124] S207: When the satellite status information meets a preset standard and when the movement prediction result meets the movement restriction condition of the first satellite communication mode, the satellite communication mode of the terminal device is switched to the first satellite communication mode.

[0125] The mobility restriction conditions for the first satellite communication mode can be constraints set for the first satellite communication mode regarding the mobility of the terminal device. These conditions are formulated based on the characteristics and performance requirements of the Tiantong satellite communication mode. For example, the terminal device's movement speed may not exceed a certain value, such as 100 kilometers per hour, because excessive movement speed may cause rapid changes in satellite signals and affect call quality. Alternatively, the terminal device's movement range may be limited to a specific area, such as the edge of the satellite's effective coverage area, to ensure a stable communication connection.

[0126] This solution identifies the terminal device's mobility information and performs time series analysis to generate a motion prediction result. This then combines satellite status information with the mobility restrictions of the first satellite communication mode to determine whether to switch communication modes, enabling the satellite communication system to more intelligently adapt to the terminal device's mobility. While the satellite status satisfies the switching conditions, the system considers whether the motion prediction result meets the requirements of the first satellite communication mode. This avoids poor communication quality after switching due to rapid movement of the terminal device or exceeding the appropriate range. This configuration of the solution can effectively improve communication stability, optimize satellite resource utilization, enhance the user's communication experience in different mobile scenarios, and avoid invalid switching caused by unusable switching after switching, which affects the normal communication of the terminal device.

[0127] Based on the above embodiments, optionally, the movement prediction result satisfies the movement restriction condition of the first satellite communication mode, including:

[0128] If the moving speed is less than the set threshold, and the predicted moving path satisfies the requirement that there is no satellite signal blocking obstacle, it is determined that the moving prediction result satisfies the moving restriction condition of the first satellite communication mode.

[0129] The set threshold can be a pre-set numerical standard for measuring movement speed. This threshold is determined based on the characteristics and performance requirements of the first satellite communication mode. The movement restriction condition of the first satellite communication mode is met only when the movement speed of the terminal device is less than the set threshold. For example, if the threshold is set to 50 km / h, then if the movement speed of the terminal device is less than 50 km / h, the movement restriction condition is met.

[0130] Satellite signal obstructions may refer to objects that can block or weaken satellite signal transmission. In satellite communications, common satellite signal obstructions include tall buildings, mountains, dense forests, or large structures. When these obstacles are located along the predicted movement path of a terminal device, the satellite signal may be blocked, weakened, or interrupted, thereby affecting the communication quality of the first satellite communication mode.

[0131] This solution makes the decision to switch satellite communication modes more rational by specifying specific criteria for the predicted movement results to meet the movement restrictions of the first satellite communication mode: namely, the movement speed must be less than a set threshold and there must be no satellite signal obstructions along the predicted movement path. By considering the impact of movement speed and movement path on satellite signals, it effectively avoids issues such as decreased communication quality and connection interruptions after switching to the first satellite communication mode due to excessive terminal device movement or signal obstructions along the movement path. This ensures communication stability in the Tiantong satellite call mode.
