[0021] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0022] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] In order to better understand the embodiments of the present application, the technical terms involved in the embodiments of the present application are explained as follows:

[0024] NR (New Radio) is a new radio access technology defined by 3GPP (3rd Generation Partnership Project) for 5G systems. Compared to previous wireless communication standards (such as 4G LTE), NR is designed to meet the diverse needs of 5G networks, including scenarios such as enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). Key features of NR technology include higher spectral efficiency, wider frequency bandwidth, lower latency, and support for various frequency bands (including millimeter waves), aiming to provide unprecedented connection speeds, capacity, and response times to support the widespread application of future 5G networks.

[0025] NTN: Non-Terrestrial Network, refers to non-terrestrial network, which is a network architecture designed to provide wireless communication services through non-terrestrial facilities (such as satellites, high-altitude platforms, drones, etc.). The purpose of NTN is to expand communication coverage, especially in areas where terrestrial network infrastructure is difficult to deploy, such as remote mountainous areas, oceans, deserts or disaster areas. NTN can provide global communication connections, make up for the lack of coverage of terrestrial networks, and ensure that communication links remain unobstructed even when the terrestrial network is damaged or does not exist. In the development of 5G and future communication technologies, NTN is regarded as an important supplementary network architecture that helps to achieve truly global seamless connectivity, especially in scenarios that require high availability and wide coverage, such as emergency communications, remote monitoring, wide-area Internet of Things and other application fields.

[0026] SAR: Specific Absorption Rate. In wireless communication devices, especially portable electronic devices such as mobile phones and tablets, the SAR value is used to measure the rate at which human tissue absorbs electromagnetic radiation, usually in watts per kilogram (W / kg). This indicator is crucial for evaluating and controlling the possible impact of using electronic devices on human health, especially when the device is used close to the human body, such as holding the phone close to the ear for a call or carrying it on the body. Countries and regions have corresponding regulations to limit the SAR value of the device to protect public health. In this application, the consideration of the SAR value is to ensure that high-power satellite terminals can still meet relevant health and safety standards while increasing the transmission power to improve the uplink.

[0027] Currently, for satellites that have already been launched and are in orbit, the uplink receiver capabilities are fixed due to the fixed payload conditions. Therefore, it is impossible to improve the uplink conditions on the satellite side after the satellite is launched. The NR stage FR1 (<7.125GHz) terminal power levels are:

[0028] PC1 (31dBm);

[0029] PC1.5 (29dBm);

[0030] PC2 (26dBm);

[0031] PC3 (23dBm)

[0032] The power levels for NB-IoT terminals are: PC3 (23dB); PC5 (20dBm); PC6 (14dBm)

[0033] Currently, all NR FR1 NTN terminal RF specifications are defined in TS38.101-5, which defines the requirements based on a 0dBi antenna gain for conducted test ports. However, in actual implementation, antenna gain is in the order of -5.5dBi, taking into account RF losses and implementation limitations.

[0034] Currently, only PC3 is defined for NR FR1-NTN terminal power levels, as shown in the following table:

[0035]

[0036] Currently, all RF specifications for IoT FR1 NTN terminals are defined within TS36.102, with different values defined based on the conducted test port. For example, based on the 0dBi antenna gain requirement, only PC3 (23dBm) and PC5 (20dBm) are defined. However, in practice, antenna gain is typically around -5.5dBi due to RF losses and implementation limitations.

[0037] That is, although standards such as TS36.102 define the RF specifications for IoT NTN terminals based on 0dBi antenna gain (ideally, the antenna has no gain or loss) and set the terminal's uplink power levels, such as PC3 and PC5, in real-world environments, the terminal antenna gain is often far below this ideal value, potentially as low as -5.5dBi. This means that even if the terminal transmits signals at the power level specified in the standard, the actual effective transmit power will be significantly reduced due to the loss of antenna gain. This is particularly disadvantageous for satellite communications, because satellites are farther from the ground, and the transmission of uplink signals must overcome greater attenuation, requiring the terminal to have higher effective transmit power.

[0038] The following table shows the definitions of terminal uplink power levels and their tolerances in different frequency bands:

[0039]

[0040] The table above further illustrates that, in accordance with the TS36.102 standard, the uplink transmit power of IoT NTN terminals in these frequency bands is limited to 23dBm and 20dBm. Considering that actual devices may have transmit power lower than the standard due to RF loss and antenna gain limitations, this may affect communication quality with the satellite, especially in scenarios requiring long-distance coverage.

[0041] Specifically, since the actual power that the terminal can achieve may be limited by the antenna gain, this means that under the existing standard framework, even if the terminal transmits according to the Class 3 or Class 5 power level, it may not be able to meet the maximum communication requirements in the satellite scenario.

[0042] Therefore, the technical problem of this application is how to increase the uplink power of the terminal while taking into account the low actual gain of the antenna, so as to overcome the physical limitations of satellite communications, enhance the uplink coverage capability, and ensure the connection stability and communication performance between the terminal and the satellite network in different scenarios, especially in emergency situations. This application proposes a terminal power level adaptation adjustment process, including the user's spontaneous application for adjustment of the working mode and the network's unified control of the terminal power level in an emergency. It aims to break through the limitations of the existing power level and allow the terminal to transmit at a higher power within the scope permitted by regulations, thereby improving the uplink condition and improving the reliability of communications, especially under realistic conditions where the RF loss and antenna gain are lower than the standard definition.

[0043] In order to solve the above problems, relevant solutions are provided in the embodiments of the present application, which are described in detail below.

[0044] According to an embodiment of the present application, a method embodiment of a terminal device power adjustment method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0045] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Figure 1 The figure shows a hardware structure block diagram of a computer terminal (or mobile device) for implementing a method for adjusting the power of a terminal device. Figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more (illustrated as 102a, 102b, ..., 102n) processors 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA), a memory 104 for storing data, and a transmission device 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of the BUS bus), a network interface, a power supply and / or a camera. It will be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above electronic device. Figure 1More or fewer components than shown, or with Figure 1 Different configurations shown.

[0046] It should be noted that the one or more processors 102 and / or other data processing circuits described above may generally be referred to herein as "data processing circuitry". The data processing circuitry may be embodied in whole or in part as software, hardware, firmware, or any other combination thereof. In addition, the data processing circuitry may be a single independent processing module, or may be incorporated in whole or in part into any of the other components of the computer terminal 10 (or mobile device). As described in the embodiments of the present application, the data processing circuitry serves as a processor control (e.g., selection of a variable resistor terminal path connected to an interface).

[0047] The memory 104 can be used to store software programs and modules of application software, such as the program instructions / data storage device corresponding to the terminal device power adjustment method in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, that is, implementing the above-mentioned terminal device power adjustment method. The memory 104 may include a high-speed random access memory and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely located relative to the processor 102, and these remote memories may be connected to the computer terminal 10 via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0048] The transmission device 106 is configured to receive or transmit data via a network. A specific example of the aforementioned network may include a wireless network provided by the communications provider of the computer terminal 10. In one embodiment, the transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In another embodiment, the transmission device 106 may be a radio frequency (RF) module, which is configured to communicate with the Internet wirelessly.

[0049] The display may be, for example, a touch screen liquid crystal display (LCD) that enables a user to interact with a user interface of the computer terminal 10 (or mobile device).

[0050] In the above operating environment, the embodiment of the present application provides a method for adjusting power of a terminal device, such as Figure 2 As shown, the method includes the following steps:

[0051] Step S202: determining a power adjustment instruction, wherein the power adjustment instruction includes a first power adjustment instruction generated in response to a user operation behavior and a second power adjustment instruction directly issued by the satellite network;

[0052] In the technical solution provided in step S202, the user can initiate a demand application through the terminal control app or the system settings interface, thereby generating a first power adjustment instruction. The initiated applications may include but are not limited to application one, application two, and application three. Application one is to turn on the satellite network and access the satellite network. Application two is to turn on the satellite network, access the satellite network and turn on the satellite pointing mode. Application three is to turn on the satellite network, access the satellite network and enter the handheld working mode. The handheld working mode means that the terminal device cannot be close to the human head, that is, the distance between the terminal device and the human head should be longer than the preset distance.

[0053] Step S204: If the power adjustment instruction is a first power adjustment instruction, the terminal device determines a target operating state and a first power level according to the first power adjustment instruction, wherein the first power level is a maximum power level allowed by the satellite network and supported by the terminal device;

[0054] In the technical solution provided in step S204, the working states of the terminal device include an ear-hearing mode working state and a handheld mode working state, wherein the power limitation requirements corresponding to the ear-hearing mode working state include a head specific absorption rate limitation requirement and a body specific absorption rate limitation requirement, and the power limitation requirements corresponding to the handheld model working state include a body specific absorption rate limitation requirement.

[0055] As an optional implementation, after the terminal device determines the device working state and the first power level based on the first power adjustment instruction, the method also includes: the terminal device sends a power adjustment signaling to the satellite network, wherein the power adjustment signaling is used to indicate the target working state and the first power level of the terminal device; after the terminal device receives the power adjustment signaling feedback information replied by the satellite network and the power adjustment signaling range information is to allow adjustment, the terminal device sets the working state of the terminal device to the target working state, and sets the uplink power of the terminal device to the first power level.

[0056] In some embodiments of the present application, after the terminal device determines the device operating state and the first power level based on the first power adjustment instruction, the method also includes: the terminal device sends a notification message to the satellite network, wherein the notification message is used to indicate that the device state of the terminal device is set to the target operating state, and the uplink power of the terminal device is set to the first power level.

[0057] As an optional implementation, the process by which a terminal device determines the device's operating state and first power level based on the first power adjustment instruction does not stop at adjusting the terminal device's internal state. It also includes a crucial step: the terminal device sends notification information to the satellite network. This information transmission not only enhances interaction between the terminal and the network, but also greatly improves the overall efficiency and reliability of the system. Furthermore, the terminal device sending notification information to the satellite network allows the network to gain access to more relevant information, enabling event assessment, early warning reporting, and network adjustments based on this information. For example, this can determine whether the event is a single or a mass event, assist in the assessment of natural disasters that can be predicted, such as meteorological, hydrological, and geological disasters. It can also collect, assess, report, and make network adjustments to disaster information other than these predictable natural disasters.

[0058] First, sending notification information to the satellite network is a necessary means for the terminal device to report its status change to the network. The importance of this step lies in that when the terminal device adjusts to the target operating state according to the instruction and sets the uplink power to the first power level, the satellite network needs to understand this change in a timely and accurate manner to synchronously update the network-side management information of the terminal device. The transmission of this information enables the satellite network to grasp the latest status of the terminal device in real time, including but not limited to whether it is in handheld mode, whether the operating mode meets the SAR (Specific Absorption Rate) limit, and the current power level setting. This is crucial for network resource allocation, connection management, and emergency communication scheduling.

[0059] Secondly, sending notification information helps the network perform subsequent optimization configuration. Satellite networks, especially NTN (Non-Terrestrial Network) networks, have significant differences in resource allocation and connection management compared to terrestrial networks. Due to the long distance between satellites and ground terminals and the large signal propagation loss, the network needs to have a precise understanding and control of the terminal's uplink power to ensure that the signals of all terminal devices can effectively reach the satellite while avoiding interference and energy consumption problems caused by excessive power. When the terminal device sends a notification message to inform the network of its current operating status and power level, the satellite network can use this information to perform more refined frequency planning and power control, thereby optimizing overall communication quality and improving system throughput and spectrum efficiency.

[0060] Furthermore, this notification mechanism effectively supports emergency communications strategies. In emergencies such as natural disasters, satellite networks must rapidly adjust communication parameters to ensure all devices can establish or maintain a connection to the network as quickly as possible. In these situations, the notification message sent by the device quickly informs the network that it has entered maximum power transmission. The network can immediately confirm and authorize this state without requiring additional power level confirmation or adjustment, significantly shortening the time it takes to initiate emergency communications. This is invaluable for ensuring instant communication capabilities in scenarios such as rescue communications and post-disaster recovery.

[0061] Finally, sending notifications to the satellite network is a critical step in maintaining system security and compliance. In some countries and regions, the transmit power of terminal devices is subject to strict regulations to protect human health and prevent electromagnetic interference. When a terminal device adjusts its power level, sending notifications ensures that the network monitors this change. Based on geographic location, time of day, and specific regulatory requirements, the network can determine whether the terminal device can safely enter the requested operating state and power level. This not only helps prevent terminal devices from violating local regulations but also ensures the secure and stable operation of the entire communication system.

[0062] In short, the seemingly simple interactive process of the terminal device sending notification information to the satellite network is actually a comprehensive reflection of many considerations such as connection management, resource optimization, emergency communications and system compliance. It not only helps the terminal device maximize its communication performance within the scope permitted by regulations, but also ensures the satellite network's real-time monitoring and flexible control of the terminal status, thereby providing users with more stable, efficient and secure communication services. Especially when facing the special needs of NTN satellite scenarios, this mechanism demonstrates its indispensable role. Through this mechanism, the present application implements a terminal power level adaptation adjustment process that not only meets regulatory requirements but also can flexibly respond to emergencies, thereby improving the reliability of satellite communications and providing technical guarantees for achieving wider communication coverage and more efficient emergency communications.

[0063] In some embodiments of the present application, for the first power adjustment instruction corresponding to application one, the terminal device can operate at the maximum power level allowed by the satellite network and supported by the terminal, but still needs to meet all relevant SAR requirements. For the first power adjustment instruction corresponding to application one, application two, or application three, the terminal device can operate at the maximum power level allowed by the satellite network and supported by the terminal, operate in handheld mode, and only need to meet the body SAR requirements. Or operate at the maximum power level allowed by the satellite network and supported by the terminal, notify the network with special uplink signaling, and enter the working state after obtaining network feedback permission. Or operate at the maximum power level allowed by the satellite network and supported by the terminal, operate in handheld mode, and only need to meet the body SAR requirements, and notify the network of this working state.

[0064] In some embodiments of the present application, the terminal device can not only dynamically adjust its working state according to the first power adjustment instruction, such as switching to handheld mode or earphone mode to optimize uplink communication performance, but is also configured with an intelligent user distance prompt and alarm mechanism to ensure that when the power level is increased, the terminal device maintains an appropriate safety distance from the human body to comply with SAR limits and protect user health.

[0065] First, when the terminal device receives the first power adjustment command from the network, instructing it to switch to handheld mode and transmit at the maximum power level, it immediately takes action, adjusting its internal circuitry and power amplifier settings to achieve the power level specified in the command. Simultaneously, the terminal device initiates a user interaction process to clearly and intuitively inform the user that the device is operating at a higher power level and that the device should be kept at an appropriate distance from specific body parts (such as the head and hands). This notification can take various forms, such as a pop-up warning message on the device's screen, clearly informing the user: "The terminal is operating in handheld mode. The power level has been increased to the maximum. Please keep the device at least 15 cm away from your head to ensure compliance with SAR requirements and protect your health." Furthermore, the terminal device may provide more immediate and intuitive reminders to the user through audible alarms or vibration feedback, ensuring that even if the user does not notice the on-screen prompt, they are aware of the need to maintain a safe distance.

[0066] To further enhance user awareness of safe distances, terminal devices also incorporate a built-in sensor-based real-time distance monitoring system. This system may include near-field sensors, accelerometers, and gyroscopes, which continuously monitor changes in the distance between the device and the body's contact area. For example, accelerometers and gyroscopes can detect the movement and tilt of the terminal device, helping to determine whether the device is being held against the ear or held firmly in the hand. Near-field sensors, on the other hand, directly measure the distance between the device and the human body.

[0067] Once it detects that the user has inadvertently placed the terminal device too close to the head or hand, resulting in a potential risk of non-compliance with SAR limits, the terminal device will immediately activate a secondary alarm mechanism. This mechanism includes displaying a more prominent warning icon or text on the screen, while the device will emit a rapid warning sound, or even provide strong tactile feedback through the device's built-in speaker or vibrator to attract the user's attention. Warning messages may include: "Warning! The device is too close to the head. Please adjust your holding posture immediately to ensure safety!" or "Attention! The power level of the terminal device has been increased. Please maintain a safe distance of at least 15 cm and avoid prolonged contact to protect the health of you and your family." These alarm messages not only remind users of the current risk status, but also provide specific advice and guidance to help users quickly take corrective actions to avoid health risks.

[0068] Optionally, if the user fails to adjust the distance between the device and the human body in a timely manner after receiving the initial alarm, the terminal device will activate a third-level alarm, which may include automatically reducing the power level to a safe range, or in extreme cases, temporarily disabling the uplink to ensure user safety. This automatic intervention mechanism is the last protective measure taken by the terminal device when the user fails to actively respond to the alarm. Its purpose is to not allow the device to get too close to the human body under any circumstances, thereby avoiding possible health risks. At the same time, the terminal device will also record this event, including detailed information such as the time the event occurred, the duration, and the distance between the device and the human body. These data can be used for subsequent device usage analysis and user education to help users better understand and comply with device usage rules under SAR limits.

[0069] In summary, in the embodiments of this application, the terminal device, through intelligent user distance prompts and alarm mechanisms, not only optimizes communication performance when the power level is increased, but also ensures the health and safety of the user during device use. Through this series of interactive designs and automatic protection measures, the technical solution of this application can provide an efficient and secure satellite communication experience, ensuring that in any scenario, the terminal device can achieve the best communication effect while protecting the user's health.

[0070] Step S206: When the power adjustment instruction is a second power adjustment instruction, the terminal device determines a second power level according to the second power adjustment instruction, wherein the second power level is a maximum power level supported by the terminal device.

[0071] In the technical solution provided in step S206, the terminal device determines the second power level based on the second power adjustment instruction, including: determining the effective time period information in the second power adjustment instruction; the terminal device adjusts the uplink power to the second power level in the time period indicated by the effective time period information, and adjusts the uplink power from the second power level back to the preset power level after exceeding the time period, wherein the power corresponding to the preset power level is lower than the power corresponding to the second power level.

[0072] As an optional implementation, after the terminal device determines the second power level based on the second power adjustment instruction, the method also includes: receiving a third power adjustment instruction issued by the satellite network; adjusting the uplink power of the terminal device from the second power level back to the preset power level based on the third power adjustment instruction, wherein the power corresponding to the preset power level is lower than the power corresponding to the second power level.

[0073] In some embodiments of the present application, the satellite network may use a unified notification message to inform the terminal device of the end of the emergency state, and the terminal device may then resume the normal preset power level. Alternatively, the second power adjustment instruction may directly or implicitly specify an effective period, and if no new notification configuration is received after the expiration of the period, the terminal device may resume the normal preset power level.

[0074] In some embodiments of the present application, the second power adjustment instruction includes a single-byte power adjustment instruction and a multi-byte power adjustment instruction, wherein the single-byte power adjustment instruction is used to prompt an emergency; the multi-byte power adjustment instruction is used to indicate the location and type of the emergency.
