[0032] The present application will be further described below with reference to the accompanying drawings and embodiments, in which:

[0033] Figure 1 It is a flowchart of an embodiment of a method for improving communication performance provided by the present application;

[0034] Figure 2 It is a hardware circuit architecture diagram of a terminal applied to a method for improving communication performance provided in this application. DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The inventors of the present application have found in long-term research that the current methods for improving communication performance to cope with critical communication mainly include: the first method is to judge that the received signal strength is in a certain range, start to increase the transmission power, increase the transmission signal strength, and achieve improved communication distance; the second method is that the receiving end chooses whether to connect to a multi-stage low-noise amplifier according to the signal strength, and improves the receiving sensitivity to achieve improved communication distance. These two methods can only improve the communication distance of the receiving end or the transmitting end, and both increase the power consumption of the terminal, thereby affecting the standby time of the terminal battery. Therefore, the present application provides a method for improving communication performance, which can simultaneously increase the receiving communication distance and the transmitting communication distance of the terminal, improve the communication quality of critical communication, and maintain the terminal standby time, and improve the terminal user experience. Below, the method provided by the present application is described in detail through specific embodiments.

[0037] Reference Figure 1 In some embodiments of a method for improving communication performance provided in the present application, the method is applied to a terminal, and the method for improving communication performance includes the following steps:

[0038] S10: Obtaining the signal strength of the received signal;

[0039] S20: Determine whether the signal strength is not greater than a preset signal strength value;

[0040] S21: When the signal strength is not greater than a preset signal strength value, entering a high sensitivity mode, wherein the receiving link of the terminal in the high sensitivity mode is a multi-stage low noise amplifier mode;

[0041] S30: after entering the high sensitivity mode, determine whether the signal strength has not decreased; if the signal strength has not decreased, proceed to step S31;

[0042] S31: Entering a power enhancement mode, wherein the transmission power of the terminal in the power enhancement mode is greater than the transmission power in the normal communication mode, and the receiving link of the terminal in the normal communication mode is a single-stage low noise amplifier mode;

[0043] S40: Start transmitting the signal and update the standby time after the transmission is completed;

[0044] S50: When standby is required, enter the standby mode according to the updated standby time.

[0045] It should be noted that if the signal strength is not greater than the preset signal strength value, it means that the terminal is currently in a critical situation of receiving signals and needs to improve communication performance. It can be imagined that if the signal strength is greater than the preset signal strength value, it means that the terminal is currently in a good communication situation and can maintain a normal communication mode to reduce the power consumption of the terminal.

[0046] It should be noted that after adopting the method of improving communication performance, the power consumption of the terminal will increase, thereby reducing the standby time of the terminal. The updated standby time refers to the increased standby time of the terminal.

[0047] Implementing the method for improving communication performance provided in this embodiment has the following beneficial effects:

[0048] 1. By increasing the receiving communication distance and transmitting communication distance of the terminal in critical communication, the communication quality of critical communication is improved;

[0049] 2. By updating the standby time and entering the standby mode according to the updated standby time, the power consumption increased by increasing the receiving communication distance and the transmitting communication distance can be offset, the terminal standby time can be maintained, and the terminal usage experience can be improved.

[0050] It should be noted that the preset signal strength value may be set to -120dBm, and those skilled in the art may also set it according to the received signal strength when the call is interrupted in actual work of the terminal, which will not be elaborated here.

[0051] It should be noted that the method for improving communication performance provided in the present application can be manually initiated by the user when the call is found to be interrupted or the mobile terminal prompts that the received signal strength is low, or it can be automatically initiated by the terminal during normal communication. Technical personnel in this field can make settings according to actual needs, which will not be elaborated here.

[0052] Reference Figure 1 In some embodiments of the present application, in step S20, it is determined that the signal strength is greater than a preset signal strength value, or, in step S30, after entering the high sensitivity mode, it is determined that the signal strength is reduced, then step S60 is executed to enter the normal communication mode.

[0053] Specifically, if the signal strength is greater than a preset signal strength value, it means that the current communication status of the terminal is good, and the normal communication mode can be maintained to reduce the power consumption of the terminal.

[0054] It should be noted that the current methods used to improve the receiving communication distance of the terminal often weaken the terminal's anti-interference ability. If the signal strength decreases after entering the high-sensitivity mode, it means that there is interference in the communication, and the high-sensitivity mode cannot improve the receiving communication distance of the terminal. At this time, you can enter the normal communication mode to reduce the power consumption of the terminal; if the signal strength increases after entering the high-sensitivity mode, it means that there is no interference in the communication, and the high-sensitivity mode can effectively improve the receiving communication distance of the terminal.

[0055] It is conceivable that after the terminal executes step S60 and enters the normal communication mode, after the communication ends, it will execute step S70 and enter the standby mode.

[0056] Reference Figure 2 In some embodiments of the present application, step S21 includes:

[0057] By controlling the switch 110 in the receiving chain 100 of the terminal, the receiving chain 100 of the terminal is switched from the single-stage low noise amplifier mode to the multi-stage low noise amplifier mode, so as to enter the high sensitivity mode from the normal communication mode.

[0058] It can be imagined that, in normal communication mode, the switch 110 in the receiving link 100 is switched to a direct-through state, that is, a single-stage low-noise amplifier mode, so as to reduce the power consumption of the terminal and improve the anti-interference ability of the terminal; when it is necessary to enter a high-sensitivity mode, the switch 110 in the receiving link 100 switches the receiving link 100 of the terminal from a single-stage low-noise amplifier mode to a multi-stage low-noise amplifier mode, thereby improving the sensitivity of the receiving link 100 to achieve the effect of increasing the communication distance, thereby improving the communication quality of critical communication.

[0059] It should be noted that Figure 2The multi-stage low noise amplifier mode in the receiving link 100 is a two-stage low noise amplifier mode, but the multi-stage low noise amplifier mode in this application includes but is not limited to two stages. Those skilled in the art can set it according to actual conditions, which will not be elaborated here.

[0060] Reference Figure 2 In some embodiments of the present application, step S31 includes:

[0061] The bias voltage of the automatic power control circuit 210 in the transmission chain 200 of the terminal is increased to enter the power boost mode.

[0062] It is conceivable that by increasing the bias voltage of the automatic power control circuit 210 during transmission and increasing the transmission power, the transmission communication distance of the terminal can be increased to improve the communication quality of critical communication.

[0063] It should be noted that the boost value of the bias voltage of the automatic power control circuit 210 during transmission ranges from 0% to 50% of the original bias voltage. Those skilled in the art can set the bias voltage within this range according to actual conditions, which will not be elaborated herein.

[0064] It should be noted that the increase value of the bias voltage in this embodiment is 20% of the original bias voltage. By increasing the bias voltage by 20%, a better balance can be achieved between the increased power consumption of the transmission link 200 and the increased transmission communication distance of the terminal, so that the power enhancement mode can effectively increase the transmission communication distance of the terminal while minimizing the increased power consumption.

[0065] In some embodiments of the present application, step S40 includes:

[0066] Obtain the standby time value consumed by the terminal in high sensitivity mode and power boost mode;

[0067] The standby time is updated according to the depleted standby time value.

[0068] It is conceivable that after adopting the communication performance improvement method, the terminal enters the high sensitivity mode and the power enhancement mode, and these two modes will increase the power consumption of the terminal, thereby reducing the standby time of the terminal. The reduced terminal standby time can be determined by obtaining the standby time value lost by the terminal in the high sensitivity mode and the power enhancement mode; the increased terminal standby time can be determined by updating the standby time according to the lost standby time value, thereby compensating for the standby time value lost by the terminal in the high sensitivity mode and the power enhancement mode.

[0069] In some embodiments of the present application, obtaining the standby time value consumed by the terminal in the high sensitivity mode and the power boost mode includes:

[0070] Get the current value in high sensitivity mode and power boost mode;

[0071] Calculate the current value increased in the high sensitivity mode and the power boost mode relative to the normal communication mode according to the current value;

[0072] The loss standby time value is calculated based on the increased current value.

[0073] It should be noted that the current value in high sensitivity mode and power boost mode refers to the current value output by the terminal in high sensitivity mode and power boost mode, and accordingly, the current value increased in high sensitivity mode and power boost mode relative to the normal communication mode refers to the current value increased by the current value output by the terminal in high sensitivity mode and power boost mode relative to the current value output by the terminal in normal communication mode.

[0074] Specifically, a low noise amplifier is added to the receiving link 100, and the output current value of the terminal is increased by a predetermined value. Therefore, the current value increased by the terminal in the high sensitivity mode can be determined according to the number of low noise amplifiers added. The current value increased by the terminal in the power enhancement mode can be obtained by converting the increased power value into the corresponding current increase value. The loss standby time value can be calculated according to the increase in the current value output by the terminal, that is, the reduced terminal standby time is determined.

[0075] In some embodiments of the present application, step S50 includes:

[0076] Adjust the time ratio between the terminal's standby state and sleep state;

[0077] The updated standby time is obtained according to the time ratio. If the updated standby time is less than the lost standby time value, the time ratio of the waiting state and the sleep state of the terminal is adjusted continuously until the updated standby time is not less than the lost standby time value.

[0078] It should be noted that the standby state is the state in which the receiving link and baseband control chip of the terminal are working. At this time, the terminal can detect the strength of the received signal. The sleep state is the state in which the receiving link and baseband control chip of the terminal stop working. At this time, the terminal maintains the operation of the minimum system and waits for the next wake-up before the receiving link and baseband control chip enter the working state. The terminal maintains the lowest power consumption in the sleep state.

[0079] It can be imagined that when the updated standby time (i.e., the increased terminal standby time) is greater than or equal to the lost standby time value (i.e., the reduced terminal standby time), the reduced terminal standby time caused by the increased power consumption in the high-sensitivity mode and the power enhancement mode can be compensated by modifying the time ratio of the terminal's standby state and the sleep state, so as to maintain the original terminal standby time. If the updated standby time is less than the lost standby time value, then modifying the time ratio of the standby state and the sleep state of the wireless terminal is not enough to compensate for the reduced terminal standby time caused by the increased power consumption in the high-sensitivity mode and the power enhancement mode, and it is necessary to continue to adjust the time ratio of the standby state and the sleep state of the terminal until the updated standby time is not less than the lost standby time value.

[0080] It should be noted that, assuming that the initial value of the time ratio of the standby state and the sleep state is 1:2, the modified time ratio is 1:Y; at this time, the larger the Y value is, the better. The larger the Y value is, the longer the sleep time is, and the more words may be lost. Therefore, modifying the time ratio is to ensure that the updated standby time is greater than or equal to the loss standby time value, which is the preferred solution. In addition, the updated standby time obtained according to the time ratio in this embodiment is obtained using an algorithm commonly used in the art, which will not be described in detail here.

[0081] In some embodiments of the present application, the method for improving communication performance further includes:

[0082] If standby is not required, continue to obtain the signal strength of the received signal.

[0083] It is conceivable that when standby is not needed, the process returns to step S10 and continues to obtain the signal strength of the received signal to determine in real time whether the terminal is in a critical communication state, thereby quickly entering a high sensitivity mode and a power enhancement mode to improve the user experience of the terminal.

[0084] It should be noted that when the terminal is a walkie-talkie or a car-mounted station, there is a high probability that the next communication will be carried out within a period of time after each critical communication or normal communication. If the standby mode is entered immediately after each communication, it may cause word loss due to sleep, thereby reducing the user experience; waiting for a period of time after the communication ends, and determining whether to enter the standby mode based on whether there is a communication request during this period of time, can reduce the situation of word loss due to sleep in the next communication after the communication ends, thereby improving the user experience.

[0085] It should be noted that the waiting time after the communication ends can be 5 seconds, and those skilled in the art can also set the specific time of the first time period according to actual conditions, which will not be elaborated here.

[0086] Furthermore, the present application also provides a terminal, including a receiving link, a transmitting link, a processor and a memory storing a computer program, the receiving link including a multi-stage low noise amplifier mode and a single-stage low noise amplifier mode, and the processor implements a method for improving communication performance of any of the above items when executing the computer program.

[0087] The processor of the present application is used to provide computing and control capabilities to support the operation of the entire wireless terminal. It should be understood that in the embodiment of the present application, the processor can be a central processing unit (CPU), and the processor can also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. Among them, the general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc.

[0088] It should be noted that the terminal provided in this application can be a walkie-talkie or a communication device such as a vehicle-mounted station.
