Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, in particular to a communication method, device, equipment, storage medium and program product. BACKGROUND

[0002] With the rapid development of science and technology, fusion perception provides a new way of thinking and method for solving complex real problems. Fusion perception refers to integrating, correlating and analyzing information obtained from multiple different types of sensors, data sources or perception means to form a more comprehensive, accurate and in-depth understanding of a specific object, environment or phenomenon. At present, in the data transmission mode for fusion perception, each micro-domain terminal (perception terminal) in the micro-domain can perform point-to-point direct communication, as shown in Figure 1 Each micro-domain terminal needs to be connected to the wide area network for information interaction under wide area network coverage. Since each micro-domain terminal needs to access the wide area network, the demand for air interface resources is huge, and the power consumption of the terminal is increased, which limits the ability of certain micro-domain services with extreme performance transmission requirements. In order to reduce the load of the wide area network, the prior art also provides another data transmission mode, as shown in Figure 2 A cluster head node or control node is newly introduced for each micro-domain, and all micro-domain terminals do not need to access the wide area network at the same time, but communicate with the wide area network through the cluster head node. Although it can reduce the load of the wide area network, the cluster head node cannot communicate with the wide area network in areas without network signal coverage, resulting in the inability to complete the perception service. SUMMARY

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] See Figure 3 , Figure 3This is a schematic diagram of a data transmission method for fused sensing provided in an embodiment of the present invention. The fused sensing communication system comprises a management platform, a core network, network devices, an NTN (Non-Terrestrial Network) gateway, satellites, terminal devices (including main terminal devices and sub-terminal devices), and tags. The dashed and solid boxes in the diagram represent the sensing processes of the terminal devices and tags, respectively. The main terminal device can directly interact with the tags, as shown in the dashed box; or, the sub-terminal devices can interact with the tags and then aggregate the information to the main terminal device, as shown in the solid box.

[0055] The management platform, acting as a remote service center, manages terminal devices through the core network. Its architecture includes a data layer, application layer, and interface layer, enabling functions such as terminal device registration and authentication, status monitoring, remote control, and configuration sensing. The management platform communicates with the core network using standard signaling protocols to transmit signaling messages for device registration, authentication, and configuration updates. For example, the Diameter protocol is used for authentication and authorization signaling interaction, ensuring secure communication between the terminal devices and the management platform.

[0056] The terminal equipment (including main terminal equipment and sub-terminal equipment) is a device with read and write capabilities, and can refer to drones, access terminals, user equipment (UE), user units, user stations, mobile stations, mobile stations, remote stations, remote terminals, mobile devices, user terminals, terminals, wireless communication equipment, user agents, or user devices. Access terminals can be cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, IoT devices, satellite handheld terminals, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, vehicle-mounted devices, wearable devices, terminal equipment in 5G networks, or terminal equipment in future evolved networks, etc.

[0057] The network equipment may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NG RAN) device, a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, vehicle-mounted equipment, wearable device, hub, switch, bridge, router, or network equipment in a future Public Land Mobile Network (PLMN), etc.

[0058] The satellite and the NTN gateway form the core of the non-terrestrial network NTN, realizing integrated air-space-ground communication. The satellite and the NTN gateway are connected via a power supply link, enabling the exchange of data and signals between the satellite and the terrestrial network. The satellite and the main terminal equipment establish a communication channel through a service link, allowing main terminal equipment within the target service area to transmit data and connect.

[0059] Based on the above communication system architecture, the communication method described in this embodiment of the invention involves two communication modes: wide area and micro area.

[0060] I. Wide Area Communication Methods

[0061] Wide-area communication uses a combination of cellular and NTN technologies. In scenarios with cellular coverage, such as... Figure 3 The main terminal devices C and D in the network use cellular communication to directly establish a connection with network device A. In scenarios without cellular coverage, such as in deserts or remote areas, for example... Figure 3 The main terminal devices A and B establish a connection with the satellite. After receiving and processing the signals from the main terminal devices A and B, the satellite transmits the signals to the ground NTN gateway connected to the core network, and finally aggregates them to the management platform.

[0062] The signaling connection between the main terminal device and the wide area access network (WAN) supports the following functions: ① The WAN coordinates resources and manages interference for multiple micro-domain networks. For example, the main terminal device measures inter-domain interference and reports the relevant information to the WAN. The WAN then performs centralized resource scheduling or resource pool allocation based on the reported measurement information. Alternatively, the WAN configures relevant parameters, and the micro-domain networks perform distributed resource selection or reselection based on the configuration information. ② The WAN manages and allocates micro-domain network resources. For example, the main terminal device sends a micro-domain network resource request to the WAN. The WAN allocates resources to the micro-domain networks within the selected resource pool. Micro-domain networks that are closer together can be allocated orthogonal resources to avoid interference, while micro-domain networks that are farther apart can reuse resources to improve spectrum efficiency.

[0063] The signaling connection between the main terminal device and the wide area core network supports the following functions: ① Registration with the wide area core network. The registration request message includes UAV information, micro-domain network type, and other relevant parameters. The core network performs authentication and information registration operations on the micro-domain network. ② Policy and configuration parameter distribution and updates. Based on the micro-domain type and other relevant information, the wide area core network configures and distributes policies and parameters related to micro-domain services to better support local micro-domain service transmission. These policies and parameters have higher priority than the corresponding pre-configured information within the micro-domain network.

[0064] II. Communication Methods in Micro-domains

[0065] In this system architecture, the main terminal device is equivalent to a micro-domain control node. Taking a drone as an example, the main communication methods between the main terminal device and the sensing end carrying passive tags are as follows:

[0066] Method 1: The main terminal device carries a tag reader / writer, see [link / reference] Figure 4 , Figure 4 This is the first communication method of the main terminal device in the micro-domain provided by the embodiment of the present invention. UAV A, as the main terminal device, flies according to a pre-set route. During the flight, UAV A first excites and sends instructions to the sensing end of the passive tag through downlink signal. The passive tag realizes the information reply of the sensing end through backscattering. Finally, UAV A obtains the data of the sensing end and the sensing data (such as video and pictures) collected by itself, thereby completing the information collection work of the corresponding area.

[0067] Method 2: The sub-terminal device carries a tag reader / writer, see [link / reference] Figure 5 , Figure 5This is the second communication method of the main terminal device in the micro-domain provided by the embodiments of the present invention. In this case, UAV B is the main terminal device, and UAVs b1 to bn are the sub-terminal devices. UAVs b1 to bn fly according to the pre-set route, obtain the data of the sensing terminal and the sensing data collected by themselves, and then send them to UAV B in a unified manner through short-range communication methods (such as star flash, Bluetooth, WIFI), so that UAV B can complete the communication with the wide area.

[0068] See Figure 6 , Figure 6 This is a flowchart of a first communication method provided in an embodiment of the present invention. The first communication method is applied to a network device, and the method includes:

[0069] S11. Broadcast the perception configuration information sent by the management platform to the main terminal device. The perception configuration information is used to instruct the main terminal device to report perception data.

[0070] S12. The sensing data sent by the main terminal device is sent to the management platform.

[0071] For example, with Figure 3 For example, when the main terminal device is within the signal coverage area of ​​the network device, the sensing configuration information and the sensing data are forwarded by the network device. For example, if main terminal devices C and D are within the cellular network coverage area of ​​network device A, network device A can directly interact with main terminal devices C and D. When the main terminal device is not within the signal coverage area of ​​the network device, the sensing configuration information and the sensing data are forwarded by the network device through a non-terrestrial network (NTN). For example, if main terminal devices A and B are not within the cellular network coverage area of ​​network device B, network device B interacts with main terminal devices A and B through the NTN network.

[0072] In this embodiment of the invention, by aggregating and reporting sensing data through the main terminal device, the load on the wide area network and the power consumption of the terminal can be reduced. Furthermore, the introduction of a non-terrestrial network (NTN) allows the transmission of sensing configuration information and sensing data even when the main terminal device is outside the network's conventional signal coverage range. This significantly expands the network's coverage and ensures communication connectivity in remote areas, at sea, in the air, and other special environments, meeting the business needs of different scenarios. In addition, the network device automatically selects the appropriate transmission method (conventional network forwarding or NTN forwarding) based on whether the main terminal device is within the signal coverage range, achieving seamless switching between the two methods. This ensures communication continuity, preventing service interruptions for users due to device movement outside the conventional coverage area and improving user experience.

[0073] Specifically, the sensing data is obtained by the main terminal device itself, or the sensing data is obtained by at least one sub-terminal device connected to the main terminal device.

[0074] For example, depending on different application scenarios and needs, perception can be achieved either by relying on the main terminal device or by utilizing the sub-terminal device. Figure 4 As shown, UAV A serves as the main terminal device and is equipped with a tag reader / writer, which can directly interact with tags within the sensing range. At this time, the sensing data can be directly sent by UAV A to the next-level network device or satellite. Figure 5 As shown, UAV B serves as the main terminal device, and UAVs b1 to bn serve as sub-terminal devices. UAVs b1 to bn are equipped with tag readers, which can directly interact with tags within the sensing range. At this time, UAVs b1 to bn report the sensing data to UAV B, and UAV B summarizes the data and then sends it to the next-level network device or satellite.

[0075] In this embodiment of the invention, the main terminal device and the sub-terminal devices can rationally allocate sensing tasks based on their own characteristics and advantages to avoid resource waste. The main terminal device may have stronger computing and communication capabilities and is responsible for processing and transmitting comprehensive data, while the sub-terminal devices focus on specific types of simple sensing tasks, such as sensor nodes being responsible for collecting single environmental data. This division of labor can improve resource utilization efficiency, extend the service life of the devices, and reduce system costs. In addition, the connection method between the main terminal device and the sub-terminal devices facilitates deployment and expansion in scenarios of different scales. In large-scale IoT applications, such as smart city construction, the main terminal device can act as a regional central node, connecting numerous sub-terminal devices to achieve sensing coverage of every corner of the city. As demand increases, more sub-terminal devices can be easily added to expand the system's sensing capabilities and coverage without requiring large-scale modifications to the main terminal device.

[0076] Specifically, the method further includes: sending a connection establishment request to the core network in response to a power-on or restart operation; and reporting location information to the network management system of the core network after receiving a connection establishment response from the core network.

[0077] For example, after a network device powers on or restarts, it needs to establish a specific connection with the core network. This process is similar to the device "handshaking" with the system's central hub after startup, informing the core network of its status and capabilities. When establishing the initial context with the core network, for Long Term Evolution (LTE) networks, the network device connects to the core network via the S1 interface; while for New Radio (NR) networks, the network device connects via the NG interface. The network device sends an NG SETUP REQUEST message to the core network's AMF (Access and Mobility Management Function). This message acts like a "letter of introduction," carrying key information about the base station, including the Global RAN Node ID (a unique code that identifies the network device globally), the RAN Node Name (the name of the network device), and the Supported TA List (the coverage area of ​​the network device, informing the core network which areas the base station can serve). This information is then stored in the core network's database. Network operators typically use NMS (Network Management System) to manage and monitor the entire communication network. The Global RAN Node ID and latitude and longitude information of network devices are also centrally stored in the NMS database for network planning, optimization, and troubleshooting.

[0078] See Figure 7 , Figure 7 This is another flowchart of the first communication method provided in the embodiment of the present invention. The perception configuration information is obtained by the core network after receiving the area information sent by the management platform, querying the network devices in the area corresponding to the area information, and forwarding it to the network devices.

[0079] For example, depending on different application requirements, the acquisition of sensing information needs to be dynamically adjusted, thus requiring modification of the acquisition parameters at the sensing end. If a point-to-point configuration method is used, the configuration time will be relatively long, especially with NTN communication, where the cell coverage area is generally between several hundred and several thousand kilometers. There are many mobile terminals within this coverage area, placing high demands on the power consumption of UAV communication. It also consumes a significant amount of air interface resources. Therefore, in this embodiment of the invention, the network device uses a broadcast method within the area to distribute configuration information. On the management platform of the remote service center, after the main terminal device establishes a connection with the data service center and sets the operating trajectories of the main terminal device and / or sub-terminal devices, the management platform will perform regional management according to latitude and longitude. By setting the operating trajectories of the main terminal device and / or sub-terminal devices, the management platform further determines the geographical area that the main terminal device and / or sub-terminal devices can cover, and represents this area in the form of coordinates. These coordinates can be common geographical coordinate systems such as latitude and longitude, used to accurately identify the location of the area on Earth. The purpose of this is to clarify the working range of the main terminal device and / or sub-terminal devices, facilitating subsequent management and task allocation. If the area corresponding to the operating trajectory of the main terminal device and / or sub-terminal device is area 11, when the data service center needs to modify the sensing configuration parameters of the sensing terminals in area 11, it first sends the area information (such as coordinate information) + sensing configuration information to the core network. The core network first uses the area information to find the network devices registered in the network management system (NMS) within area 11, establishes connections with these network devices, and forwards the sensing configuration information to the main terminal device within area 11 through the network devices.

[0080] In this embodiment of the invention, the core network, based on the regional information sent by the management platform, can accurately forward sensing configuration information to network devices within a specific region. This ensures that only devices located in the target region receive the corresponding configuration instructions, avoiding unnecessary information transmission and interference. For example, in environmental monitoring scenarios in different urban areas, the requirements for monitoring parameters, frequencies, etc., may vary. This method allows for precise sensing configuration tailored to the actual needs of each region, improving the accuracy and effectiveness of monitoring. Furthermore, it avoids broadcasting sensing configuration information to the entire network, reducing unnecessary data transmission and lowering network load. The core network only forwards information to network devices in specific regions, enabling more rational allocation and utilization of network bandwidth and other resources, thus improving network operating efficiency. This mechanism allows the system to flexibly adjust sensing configurations according to the characteristics and changes of different regions. When the service requirements of a region change, the management platform only needs to send the corresponding regional information and new sensing configuration information, and the core network can accurately forward it to the network devices in that region, achieving rapid configuration updates and adaptation.

[0081] For example, the perception configuration information includes at least one of the following:

[0082] 1) Status indicators of the sensing switch;

[0083] For example, the status indicator is used to indicate whether the sensing function is on or off. If it is "on", it means that the sensing terminal device is allowed to perform sensing operations such as data collection according to the set requirements; if it is "off", the relevant sensing activities are stopped. The management platform can flexibly control whether the sensing task is executed. For example, during periods or in areas where data collection is not required, the sensing switch can be set to "off" to save energy and reduce data transmission; when needed, it can be set to "on" to start the sensing function.

[0084] 2) Service area;

[0085] For example, service areas are used to classify and differentiate sensing tasks and devices in different spatial ranges. For instance, different areas have different environmental monitoring needs, and different sensing parameters can be set for different areas.

[0086] 3) Perceive task categories;

[0087] For example, sensing tasks can be categorized in various ways depending on the application scenario, such as environmental monitoring (monitoring temperature, humidity, air quality, etc.), security monitoring (monitoring personnel activities and abnormal events), and geographic surveying (measuring terrain and creating maps). The management platform clarifies the nature and direction of the sensing tasks, enabling devices to collect and process data according to corresponding rules and algorithms. For instance, environmental monitoring sensing devices focus on collecting environmental indicator data, while security monitoring devices pay attention to abnormal behaviors in images and videos.

[0088] 4) Perceive data types and their configuration information.

[0089] For example, the type of data to be sensed refers to the type of data collected during the sensing process. This type of data includes at least one of the following: sensor data, video data, and image data. For instance, in environmental monitoring, the type of data to be sensed could be temperature data, humidity data, PM2.5 concentration data, etc.; in security monitoring, it could be image data or video data; and in geographic mapping, it could be elevation data, coordinate data, etc. The configuration information for the sensed data can be set for different types of sensed data. For example, the sampling period for sensor data can be configured, the video resolution, bit rate, and frame rate for video data can be configured, and the image resolution and color depth for image data can be configured.

[0090] Specifically, the perception configuration information can be broadcast in two ways: the first is to send it using existing system information, and the second is to send it using newly added system information.

[0091] In a first embodiment, the perception configuration information is carried by first information, which is obtained by updating the extended fields in existing system information to the perception configuration information.

[0092] For example, the first information is SIB25, which is a specific type of system information block in SIB (System Information Block). Wide-area configuration information is added to SIB25. The original structure of SIB25 is as follows:

[0093]

[0094] The SIB25 structure originally consists of a sequence (SEQUENCE) structure. The "coverageAreaInfoList-r18" field represents a list of coverage area information, the "lateNonCriticalExtension" field is a delay-free extension that the terminal can ignore or consider as a default value, and "OCTET STRING" represents an eight-bit string, a common data type in communications. By changing "lateNonCriticalExtension" to "PerceptualInfo," the complete SIB25 information is as follows:

[0095]

[0096]

[0097] Specifically, "lateNonCriticalExtension" is changed to "PerceptualInfo" to form a new SIB25 structure. This new structure remains a SEQUENCE, containing elements such as "coverageAreaInfoList-r18" and "PerceptualInfo". This modification signifies the introduction of perception-related information transmission capabilities into SIB25. "PerceptualInfo" is a SEQUENCE structure that consistently contains two fields: switch and precision-Type. switch indicates whether a function is enabled or disabled, with values ​​of enabled or disabled. Precision-Type identifies the data type, with values ​​of sensor data, videos data, or images data.

[0098] For the three types of sensor data—sensor data, video data, and image data—the following three precision-Type settings can be configured:

[0099] 1) When precision-Type is sensor data, the PerceptualInfo information is as follows:

[0100]

[0101]

[0102] When the sensing data type is sensor data, in addition to the common switch and precision-Type fields, sampling-Period and precision fields are added. Sampling-Period is an integer (INTEGER), ranging from 0 to 4294967295; precision is the time unit used to represent accuracy, with values ​​including millisecond, second, minute, hour, day, and week. These parameters are used to configure the sensor data acquisition parameters in a more detailed manner.

[0103] 2) When precision-Type is video data, the PerceptualInfo information is as follows:

[0104]

[0105] When precision-Type is set to video data, in addition to the common switch and precision-Type fields, new fields for video resolution, bitrate, and frame rate are added. Video resolution values ​​include SD, HD, FHD, and UHD; bitrate values ​​include bps, Kbps, and Mbps; and frame rate values ​​include 15fps, 30fps, and 60fps. These parameters are used to configure the relevant attributes of the video data.

[0106] 3) When precision-Type is images data, the PerceptualInfo information is as follows:

[0107]

[0108]

[0109] When precision-Type is set to image data, in addition to the common switch and precision-Type fields, image resolution and image color fields are added. Image resolution can take values ​​of SD, HD, FHD, and UHD; image color can take values ​​of 8-bit, 16-bit, and 24-bit. These parameters are used to configure the relevant attributes of the image data.

[0110] In the second embodiment, the perception configuration information is carried by second information, which is newly added system information.

[0111] For example, the second piece of information is a newly added SIB26, and the structure of the newly added SIB26 is as follows:

[0112]

[0113] SIB26 is defined as a SEQUENCE data structure, meaning it contains a series of ordered elements, facilitating the organization and parsing of different types of information. The information in perceptualInfo is described in SIB25 above and will not be repeated here.

[0114] In this embodiment of the invention, sensing configuration information is sent by broadcasting first or second information. This allows the main terminal device to listen only to a specific broadcast channel, significantly reducing its energy consumption and extending the battery life of both the main and sub-terminal devices by eliminating the need for a wide area network connection. Regarding air interface data transmission efficiency, multiple main terminal devices can simultaneously receive the broadcast sensing configuration information, thereby improving data transmission efficiency. Furthermore, this method conserves valuable air interface resources, reducing congestion and interference problems that may result from multiple connections competing for air interface resources.

[0115] Furthermore, combined Figure 7 The system architecture shown illustrates the embodiments of the present invention in detail. It consists of three main processes: fusion perception configuration process, data collection process, and data reporting process. The detailed process is as follows:

[0116] A. Configuration process for fused perception

[0117] 1.1 The management platform performs path planning for the main terminal devices;

[0118] 1.2 When the management platform starts the sensing function, it sends the regional information and sensing configuration information to the core network;

[0119] 1.3 The core network first identifies the area information. For example, if it identifies area 11, it finds the network devices registered in area 11, establishes connections with these network devices, and sends the perception configuration information to the network devices.

[0120] 1.4 If it is a cellular network device, it can directly broadcast the sensing configuration information via SIB; if it is an on-board network device, it continuously monitors its own location and status during operation, and only sends the sensing configuration information via SIB when it detects that it has entered area 11.

[0121] 1.5 The main terminal device receives and parses the SIB content, and forwards the parsed data to the corresponding sub-terminal device through short-range communication methods (such as star flash, Bluetooth, WIFI); if the main terminal device interacts directly with the tag at this time, the main terminal device processes the sensing configuration information and does not need to send this sensing configuration information to the sub-terminal device.

[0122] 1.6 The sub-terminal device (or main terminal device) processes the sensing configuration information, for example, by using the following processing methods:

[0123] a. Adjusting sensing parameters: If the configuration information includes parameters related to the type of sensing data (such as temperature, humidity, image, etc.) and sensing accuracy, the sub-terminal device will adjust the working mode of its own sensor based on this information. For example, if the type of sensing data is image data and a high resolution requirement is specified, the sub-terminal device will set the camera to high-resolution shooting mode; if the sensing type is environmental monitoring and a temperature monitoring accuracy of ±0.1℃ is required, the sub-terminal device will adjust the sampling frequency and accuracy settings of the temperature sensor.

[0124] b. Activating or deactivating relevant functional modules: The sensor switch and sensor type information will determine whether the sub-terminal device activates certain specific functional modules. For example, if the sensor type is security monitoring and the sensor switch is "on," the sub-terminal device will activate the image recognition and analysis module to perform real-time analysis of the collected image or video data to detect whether there are abnormal behaviors or targets.

[0125] c. Configure data storage and transmission methods. Based on the perceived data type and configuration requirements, the sub-terminal device will configure appropriate data storage formats and transmission methods. For large amounts of image or video data, compressed storage may be selected to save storage space, and appropriate transmission rates and protocols will be selected based on network conditions to transmit the data to the designated receiving end (such as a remote service center or other data processing equipment).

[0126] d. Calibration and Synchronization: Sub-terminal devices may perform sensor calibration based on configuration information to ensure the accuracy of collected data. Simultaneously, they will synchronize with other sub-terminal devices to ensure data acquisition and processing are performed on the same time base, improving data consistency and reliability.

[0127] e. Task priority processing: If multiple sensing configuration information is received at the same time or multiple tasks exist, the sub-terminal device will sort and prioritize the tasks according to the priority settings in the configuration information, and execute the high-priority tasks first to ensure the timely completion of critical tasks.

[0128] B. Data Collection Process

[0129] 2.1 The sub-terminal device spends most of its time in sleep or charging mode, only activating the sensing and data collection function when the sensing switch is turned on or the configuration cycle time has elapsed. For example, if it needs to sense sensor data (temperature, humidity, air pressure), it can transmit excitation carrier waves and signaling to the sensing terminal carrying the tag; at the same time, it can use the camera carried by the sub-terminal device to collect images or videos according to the specified line and preset frame rate.

[0130] 2.2 After receiving the excitation carrier, the tag backscatters the corresponding end-sensing signal to the sub-terminal device;

[0131] 2.3 The sub-terminal device completes the collection of all sensing information and reports it to the main terminal device;

[0132] 2.4 After the main terminal device performs data cleaning and processing, it caches the data locally, waiting for the next access time.

[0133] C. Data Reporting Process

[0134] 3.1 The main terminal device establishes a connection with the network device and sends the locally cached sensing data to the network device through the same air interface;

[0135] 3.2 Network devices forward the sensed data to the core network;

[0136] 3.3 The core network sends the sensing data to the management platform of the remote service center;

[0137] 3.4 The management platform completes the final data processing. Based on the results of the data processing, the collection of sensing information can be dynamically adjusted according to application requirements.

[0138] Compared to existing technologies, the communication method disclosed in this invention reduces the load on wide area networks and lowers terminal power consumption by summarizing and reporting sensing data through the main terminal device. By introducing a non-terrestrial network (NTN), sensing configuration information and sensing data can still be transmitted via NTN even when the main terminal device is outside the network's normal signal coverage area. This significantly expands network coverage and ensures communication connectivity in remote areas, at sea, in the air, and other special environments, meeting business needs in different scenarios. Furthermore, the network device automatically selects the appropriate transmission method (conventional network forwarding or NTN forwarding) based on whether the main terminal device is within signal coverage, achieving seamless switching between the two methods. This ensures communication continuity, preventing service interruptions for users due to device movement outside normal coverage areas and improving user experience.
