[0097] 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.

[0098] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0099] 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 more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can 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) and 5G, etc.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0105] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. 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 the corresponding connection device 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 commands sent by the processor 110 and execute them. In addition, 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.

[0106] Optionally, the touch panel 1071 may overlay the display panel 1061. 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.

[0108] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0109] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0110] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby managing functions such as charging, discharging, and power consumption through the power management system.

[0126] CHO, Conditional Handover, conditional switching;

[0127] Feeder Link, feeder link;

[0128] Service Link, service link;

[0129] MAC CE, Media Access Control Control Element, media access control control element;

[0130] NTN, Non Terrestrial Network, non-terrestrial network;

[0133] TN, Terrestrial Network, ground network.

[0134] Referring to FIG. 5 , FIG. 5 is a schematic diagram of feeder link switching in a moving satellite (Earth Moving) scenario.

[0135] In some implementations, the terminal device's movement speed is relatively static relative to the mobile satellite. Due to feeder link switching and / or service link switching, the terminal device frequently switches between two ground base stations, deletes the conditional switching configuration, and implements reconfiguration (reconfiguration of conditional switching), resulting in network signaling overhead.

[0136] And / or, when a terminal device that is performing a service link condition switching evaluation receives a switching command (Feeder link switching), there is no switching conflict resolution method according to the prior art, which may cause the terminal to repeatedly switch and / or cause signaling overhead.

[0137] As shown in FIG5 , the terminal device performs a Service link CHO measurement and evaluation, during which the Feeder link triggers a handover, resulting in a handover conflict.

[0138] At time T0, the terminal device's service satellite is Sat.A, where Sat.A is connected to the ground station (GW1, Gateway1) or base station gNB1.

[0139] At time point T1, Sat.A performs handover with the new ground station GW2 or gNB2 due to movement. The terminal device switches to the new base station based on conditional handover and deletes the conditional handover parameters configured on the source base station.

[0140] Optionally, after the terminal device switches to a new base station, the new base station configures corresponding conditional switching parameters to the terminal device, and the terminal device then performs conditional switching evaluation.

[0141] Optionally, because Sat.A continues to move forward and Sat.B moves in the direction of Sat.A's movement, the terminal device again performs conditional switching to the source base station (gNB1). For example, the terminal device again evaluates the service link switching and switches to Sat.B, where Sat.B is connected to the ground station GW1.

[0142] Optionally, Sat.A implements the feeder link switching by sending a feeder link switching command to the terminal device and / or the terminal device performs the switching according to preconfigured switching parameters.

[0143] Optionally, before implementing the Feeder link switching, the terminal device implements a service link switching evaluation and implements neighboring cell measurements through the (Location-base) CHO measurement conditions. At this time, the Feeder link switching command is received. After the terminal device implements the switching, it receives new conditional switching configuration information, and then implements the conditional switching evaluation and switches to the neighboring cell based on the newly configured conditional configuration, resulting in repeated switching and / or signaling overhead.

[0144] From the above scenarios, it can be seen that there is currently no suitable switching method to reduce signaling overhead for feeder link switching. For example, through traditional switching methods, network equipment needs to send switching commands to all terminal devices; or, through traditional conditional switching, the terminal device cannot know when to implement the conditional switching, thus causing signaling overhead and / or inability to switch.

[0145] The technical solution of the present application is to send switching indication information and / or pre-configured switching parameters through the network device, and the terminal device performs preset processing based on the switching indication information and / or pre-configured switching parameters, which can reduce the network device from sending reconfiguration signaling and / or reduce terminal signaling processing, thereby achieving the effect of reducing signaling overhead and / or reducing switching delay, and / or resolving switching conflict problems.
