[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] The signal transmission method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. The electronic device 102 responds to the triggering operation of the emergency communication mode and connects to the target frequency band; when the target frequency band is connected, the target power is determined; the target power is higher than the transmission power of the conventional communication mode; the communication signal is transmitted using the target power; the target base station 104 is determined within the coverage range of the communication signal, and the electronic device 102 communicates with the target base station 104. Among them, the electronic device 102 can be a terminal or a server; the terminal can be but not limited to various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, smart cars, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server can be implemented with an independent server or a server cluster composed of multiple servers. Among them, the target base station 104 is a public mobile communication base station, an interface device for mobile devices to access the Internet, and a form of radio station, which refers to a radio transceiver station that transmits information between mobile phone terminals through a mobile communication exchange center in a certain radio coverage area. The base station can include a macro base station, a micro base station, a radio frequency remote base station or an edge station, etc.

[0033] In one embodiment, Figure 2 As shown, a signal transmission method is provided, which is applied to Figure 1 The electronic device in the example is used to illustrate, and the following steps are included:

[0034] Step S202, in response to the triggering operation of the emergency communication mode, connecting to the target frequency band.

[0035] The emergency communication mode is a mode preset in the electronic device for communication in a signal emergency situation. It is understandable that the emergency communication mode is usually turned on when the electronic device is in a poor signal. In other optional embodiments, the electronic device can also turn on the emergency communication mode in response to the user's triggering operation on the emergency communication mode when the signal is good.

[0036] A frequency band refers to a frequency range of continuous electromagnetic waves. The target frequency band is the frequency band selected for connection in the emergency communication mode.

[0037] Optionally, the electronic device displays a developer mode page; the developer mode page displays configuration items of the emergency communication mode; in response to a trigger operation on the configuration items of the emergency communication mode, the electronic device enters the emergency communication mode, determines a target frequency band in the emergency communication mode, and connects to the target frequency band.

[0038] For example, the electronic device is in the mountains and the signal is poor. The user turns on the developer mode in the electronic device and displays the developer mode page, which includes the configuration items of the emergency communication mode. The user triggers the configuration items of the emergency communication mode and enters the emergency communication mode.

[0039] Step S204, in the case of connecting to the target frequency band, determining the target power; the target power is higher than the transmission power of the conventional communication mode.

[0040] The target power is the power used to transmit communication signals in the emergency communication mode. The normal communication mode is a mode preset in the electronic device for communication under normal circumstances.

[0041] It is understandable that when a user turns on the emergency communication mode, a higher transmission power is required to transmit the communication signal, so that the coverage of the communication signal is larger and the success rate of the electronic device connecting to the base station for communication is higher. Therefore, the target power of the emergency communication mode is higher than the transmission power of the regular communication mode, and the coverage of the communication signal transmitted in the emergency communication mode is greater than the coverage of the communication signal transmitted in the regular communication mode.

[0042] Optionally, when the electronic device is connected to the target frequency band, an increase value corresponding to the transmission power of the conventional communication mode is determined, and the transmission power of the conventional communication mode is added to the increase value to obtain the target power of the emergency communication mode. The increase value is greater than 0.

[0043] Optionally, when the electronic device is connected to the target frequency band, the maximum transmit power corresponding to the chip in the electronic device is used as the target power. It is understandable that when the electronic device uses the maximum transmit power corresponding to the chip as the target power, the electronic device transmits the communication signal at the maximum transmit power and connects to the base station with the maximum coverage of the communication signal, which can maximize the success rate of communication between the electronic device and the base station.

[0044] Step S206: transmitting a communication signal using the target power.

[0045] Optionally, the electronic device transmits a communication signal using the target power, connects to a base station within the coverage of the communication signal, and communicates with the base station.

[0046] Optionally, after connecting to the base station, the electronic device determines the location of the base station and the transmission power corresponding to the location of the base station covered by the transmitted communication signal, and transmits the communication signal with the transmission power corresponding to the location of the base station covered by the transmitted communication signal.

[0047] It can be understood that after connecting to a base station, the electronic device can determine the location of the base station, thereby determining the transmission power corresponding to the location of the base station covered by the communication signal transmitted by the electronic device. That is, the electronic device uses the transmission power corresponding to the location of the base station to transmit the communication signal, which can accurately cover the base station and avoid the waste of resources or communication problems caused by using too high or too low power to transmit communication signals.

[0048] In the above signal transmission method, the electronic device responds to the trigger operation of the emergency communication mode and connects to the target frequency band in the emergency communication mode; when connecting to the target frequency band, the target power is determined, and the target power is higher than the transmission power of the conventional communication mode. Then, the communication signal is transmitted with the higher target power, which can make the coverage of the communication signal wider, and improve the success rate of the communication connection between the electronic device and the base station in an emergency. In addition, the above signal transmission method provides users of electronic devices with an additional emergency communication means different from satellite communication, and provides an emergency communication mode that transmits communication signals with high power beyond the limitations of conventional communication modes, thereby increasing the success rate of communication connections in users' emergency situations.

[0049] In one embodiment, in response to a trigger operation of an emergency communication mode, connecting a target frequency band includes: in response to a trigger operation of the emergency communication mode, acquiring each connected candidate frequency band; determining a target frequency band from each candidate frequency band, and connecting the target frequency band.

[0050] Optionally, in response to the triggering operation of the emergency communication mode, the electronic device obtains each candidate frequency band connected within a preset time; determines a target frequency band from each candidate frequency band, and connects to the target frequency band. The preset time can be set as needed. Exemplarily, the preset time can be 2 hours, 5 hours, 1 day, etc.

[0051] Optionally, the electronic device determines a candidate frequency band with the highest signal strength from various candidate frequency bands as the target frequency band.

[0052] Optionally, determining the target frequency band from each candidate frequency band includes: determining, among each candidate frequency band, a candidate frequency band whose connection time and current time are closest as the target frequency band.

[0053] It is understandable that the frequency band to which the electronic device has been most recently connected is usually the frequency band with the highest signal strength.

[0054] In this embodiment, the electronic device obtains each candidate frequency band that has been connected in response to the triggering operation of the emergency communication mode, so that a more suitable target frequency band can be determined from each candidate frequency band.

[0055] In one embodiment, the invention is applied to an electronic device, which includes a chip; when connected to a target frequency band, a target power is determined, including: when connected to the target frequency band, a maximum power corresponding to the chip in an emergency communication mode is determined; the transmission power in a conventional communication mode is increased to obtain a target power; the target power is lower than or equal to the maximum power.

[0056] Optionally, when the electronic device is connected to the target frequency band, it determines the maximum power of the chip in the emergency communication mode corresponding to the target frequency band connected to the chip; determines the power increase value for converting from the conventional communication mode to the emergency communication mode; and adds the transmission power of the conventional communication mode to the power increase value to obtain the target power.

[0057] The power increase value can be set as needed.

[0058] Exemplarily, when an electronic device is in an emergency communication situation, such as in a remote area at the edge of a cell with only one cell nearby, the emergency communication mode is activated. When the electronic device connects to the most recently connected target frequency band, it breaks through the preset transmission power and safety power limitations of the chip and increases the transmission power of the conventional communication mode by 3dB to obtain the target power, or increases the transmission power of the conventional communication mode to the maximum power of the chip corresponding to the emergency communication mode. This can double the coverage of the transmitted communication signal and try to establish emergency communication for the user.

[0059] Among them, in the factory settings of the electronic device, in the normal communication mode, the maximum safety and target power of the chip connected to the target frequency band Band41 is 24dBm. If the electronic device turns on the emergency communication mode, the Band41 connected by the chip will ignore security, stability and protocol compliance, and force the target power to break through to 27dBm. The coverage range of the communication signal emitted by the electronic device will be doubled, thereby establishing a connection with the nearest base station.

[0060] Among them, the target power is limited by four values: the safety value of the chip to stably transmit communication signals, the optimal balance value of various indicators during the communication process, the maximum power of the communication protocol, and the maximum power of the chip.

[0061] In normal communication mode, the transmission power of electronic devices is lower than the safe value of stable transmission of communication signals by the chip, the optimal balance value of various indicators during communication, and the maximum power of the communication protocol. In emergency communication mode, the target power of electronic devices is greater than the transmission power in normal communication mode and lower than or equal to the maximum power of the chip.

[0062] In this embodiment, when the electronic device is connected to the target frequency band, it determines the maximum power of the chip in the emergency communication mode, and then increases the transmission power of the conventional communication mode to obtain the target power, and the target power is lower than or equal to the maximum power, so the target power is accurately increased to avoid damage to the chip due to excessive target power, thereby improving safety.

[0063] In one embodiment, it is applied to an electronic device; after transmitting a communication signal with a target power, it also includes: determining a target base station within the coverage range of the communication signal and establishing a connection with the target base station; the target power is positively correlated with the coverage range of the communication signal; and communicating with the target base station within a preset time period.

[0064] The target base station is the base station to which the electronic device is connected in the emergency communication mode. It is understandable that the target power corresponding to the emergency communication mode is higher than the transmission power corresponding to the conventional communication mode. Therefore, the coverage range of the communication signal corresponding to the target power is greater than the coverage range of the communication signal corresponding to the transmission power. The preset duration can be set as needed.

[0065] Optionally, the electronic device determines each candidate base station within the coverage of the communication signal, determines a target base station from among the candidate base stations, and establishes a connection with the target base station.

[0066] Among them, the electronic device can determine the base station closest to the electronic device from various candidate base stations as the target base station, or determine the candidate base station with the strongest signal from various candidate base stations as the target base station, or select the selected candidate base station as the target base station in response to a selection operation, but is not limited to this.

[0067] Optionally, if the electronic device fails to connect to the target base station, it reconnects to the target base station; if the number of failed connections between the electronic device and the target base station reaches a preset number, it re-determines the target base station and establishes a connection with the new target base station. The preset number can be set as needed, such as 3 times.

[0068] Optionally, the above method also includes: if the connection time between the electronic device and the target base station exceeds a preset time, exiting the emergency communication mode.

[0069] The electronic device includes a power amplifier (PA); under high power conditions, the power amplifier usually does not burn out instantly, but will burn out after a certain period of time. Therefore, the electronic device sets the preset time to be less than the safe time corresponding to the power amplifier burning out; the safe time is the time the power amplifier works in the emergency communication mode to avoid burning out under high power conditions. The safe time corresponding to the power amplifier burning out can be directly obtained from the manufacturer.

[0070] It is understandable that when the electronic device turns on the emergency communication mode, in order to take into account a certain degree of safety, the electronic device communicates with the target base station within a preset time. If the connection time between the electronic device and the target base station exceeds the preset time, in order to avoid burning the power amplifier, the emergency communication mode is exited.

[0071] In this embodiment, the electronic device determines the target base station within the coverage of the communication signal, the target power is positively correlated with the coverage of the communication signal, and can successfully establish a connection with the target base station, and communicate with the target base station within a preset time. Furthermore, if the connection time between the electronic device and the target base station exceeds the preset time, the emergency communication mode is exited, avoiding the problem of the electronic device continuously working under high power conditions and burning the components in the electronic device, thereby improving safety and reliability.

[0072] In one embodiment, applied to an electronic device, in response to a triggering operation of an emergency communication mode, connecting to a target frequency band, includes: in response to a triggering operation of the emergency communication mode, displaying a disclaimer page corresponding to the emergency communication mode; in response to a signing operation on the disclaimer page, entering the emergency communication mode, and in the emergency communication mode, connecting to the target frequency band.

[0073] The disclaimer page includes disclaimer content, which indicates that the manufacturer of the electronic device is exempted from the responsibility caused by the electronic device entering the emergency communication mode. The disclaimer content may include that the electronic device that has turned on the emergency communication mode is no longer entitled to after-sales warranty and is considered man-made damage.

[0074] The signing operation may be a pattern of a user's name generated by sliding on the disclaimer page, or a triggering operation of a confirmation button on the disclaimer page, or other operations, which are not limited here.

[0075] It is understandable that after the electronic device enters the emergency communication mode, the electronic device transmits communication signals at a higher target power. At a higher target power, the components in the electronic device are easily damaged. Therefore, the electronic device responds to the user's triggering operation of the emergency communication mode and displays the disclaimer page corresponding to the emergency communication mode; in response to the signing operation of the disclaimer page, it indicates that the user agrees to the disclaimer sound content in the disclaimer page, and then enters the emergency communication mode.

[0076] In this embodiment, the electronic device responds to the triggering operation of the emergency communication mode and displays the disclaimer page corresponding to the emergency communication mode. In response to the signing operation of the disclaimer page, it enters the emergency communication mode. This allows the electronic device to transmit communication signals at high power for communication while also protecting the rights and interests of the manufacturer of the electronic device.

[0077] In one embodiment, a signal transmission method is provided, which is applied to an electronic device, wherein the electronic device includes a chip; the signal transmission method includes the following steps:

[0078] Step A1, in response to the triggering operation of the emergency communication mode, display the disclaimer page corresponding to the emergency communication mode.

[0079] Step A2, in response to the signing operation on the disclaimer page, enter the emergency communication mode, and in the emergency communication mode, obtain each connected candidate frequency band.

[0080] Step A3: determine the candidate frequency band whose connection time is closest to the current time among the candidate frequency bands as the target frequency band, and connect the target frequency band.

[0081] Step A4, when connected to the target frequency band, determining the maximum power of the chip in the emergency communication mode.

[0082] Step A5, increasing the transmission power of the conventional communication mode to obtain a target power; the target power is lower than or equal to the maximum power, and the target power is higher than the transmission power of the conventional communication mode.

[0083] Step A6, transmitting a communication signal with a target power.

[0084] Step A7, determining a target base station within the coverage of the communication signal, and establishing a connection with the target base station; the target power is positively correlated with the coverage of the communication signal.

[0085] Step A8: communicate with the target base station within a preset time period.

[0086] Step A9: if the connection time between the electronic device and the target base station exceeds a preset time, the emergency communication mode is exited.

[0087] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders.
