[0002] The current IoT-NTN network requires simultaneous connections between satellites and terminal devices, as well as between satellites and ground stations, to provide services. However, due to satellite mobility and limitations on ground station deployment in actual deployments, the link between satellites and ground stations cannot be guaranteed to always exist, which in turn limits the flexibility of IoT-NTN network deployment.

[0074] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination."

[0083] Please refer to Figure 1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0084] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0085] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and / or other components. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications may use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G and 6G, etc.

[0086] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0087] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0088] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0089] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive corresponding connected devices according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive and execute commands sent by the processor 110. And / or, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0112] First embodiment

[0113] 5 , which is a flow chart of a processing method according to a first embodiment, the processing method of the embodiment of the present application can be applied to a terminal device (such as a mobile phone), including the following steps:

[0114] S2: Determine an operating mode and / or a mode switching time of the network device based on the first information.

[0115] As a non-terrestrial communication network, the IoT-NTN network may include network devices, terminal devices, ground stations, and links connecting the three. Optionally, the network devices may be communication devices such as satellites or base stations. In the embodiments of this application, satellites are used as an example for illustration.

[0116] Optionally, the link between the satellite and the terminal device is a service link, and the link between the satellite and the ground station is a feeder link. The current IoT-NTN network requires both the service link and the feeder link to be connected simultaneously to provide services. Due to satellite mobility and the limitations of ground station deployment in actual deployment, it cannot be guaranteed that the link between the satellite and the ground station will always exist. Therefore, a store-and-forward mode (S&F, Store&Forward mode) is proposed. When a network device has no feeder link connection, it can be considered to be in store-and-forward mode.

[0117] Optionally, the operating mode includes a store-and-forward mode and / or a normal operating mode.

[0118] Optionally, when the network device is in store-and-forward mode, the network device can receive and store data from the terminal device until communication with the ground station is restored and / or established, and then the stored data will be forwarded to the ground network (i.e., the ground station). At this time, the network device is considered to be in normal working mode (also known as normal mode).

[0119] Optionally, the first information includes at least one of working mode information, mode conversion information and discontinuous coverage information.

[0120] Optionally, the first information may be a system message or other downlink message, or an identifier or index carried in the signaling, used to enable the terminal device to know the link connection status and / or working mode of the network device. The form of the first information is not specifically limited in the embodiment of the present application.

[0121] Optionally, the terminal device may determine which operating mode the network device is currently in based on the operating mode information.

[0127] Optionally, when the terminal device determines that the network device operates in store-and-forward mode, if the terminal device uplink data volume is less than or equal to the store-and-forward mode traffic volume threshold, the terminal device is allowed to initiate a connection establishment request and / or send data.

[0128] Optionally, when the terminal device determines that the network device is operating in store-and-forward mode, if the interval between the current time and the mode conversion time is less than or equal to the effective duration of the store-and-forward mode data storage, the terminal device is allowed to initiate a connection establishment request and / or send data.

[0129] Optionally, when the terminal device determines that the network device operates in the store-and-forward mode, if the current service type of the terminal device is a delay-insensitive service, the terminal device is allowed to initiate a connection establishment request and / or send data.

[0130] Optionally, when the network device is in store-and-forward mode, it receives and / or stores data sent by the terminal device.

[0131] Optionally, if the storage amount of the network device in the store-and-forward mode reaches a preset threshold, the network device may actively deactivate the corresponding cell.

[0132] Optionally, when the data stored in the network device exceeds the effective storage time of the data in the store-and-forward mode, the timed-out data may be discarded.

[0133] Optionally, when the network device switches from the store-and-forward mode to the normal operating mode (ie, the feeder link connection is restored), the stored data is forwarded to the ground network.

[0134] Optionally, when the network device forwards the stored data to the ground network, it can forward the data in the order of storage time.

[0135] Optionally, when forwarding stored data to the ground network, the network device may forward the data according to the importance and / or urgency and / or priority of the stored data.

[0136] Optionally, when the terminal device determines that the network device is in a normal working mode, it does not determine the size of the uplink data volume, the interval between the current time and the mode conversion time, and the current service type.

[0137] Optionally, if the time interval between the current time and the next time the network device enters store-and-forward mode is less than or equal to a specific threshold (e.g., the time required for the current service connection), then no connection establishment request is initiated and / or data is sent. Optionally, the specific threshold can be determined independently by the terminal device, that is, when the terminal device determines that the time interval between the current time and the next time the network device enters store-and-forward mode is insufficient to complete the service, then no connection establishment request is initiated and / or data is sent.

[0138] This embodiment, through the above-mentioned scheme, specifically by determining the working mode and / or mode conversion time of the network device based on the first information, provides a method for determining the working mode and / or mode conversion time of the network device, thereby improving the adaptability of the terminal service, and / or enabling the terminal device to operate in the storage and forwarding mode, which helps to reduce the deployment of ground stations and / or improve the flexibility of ground station deployment.
