All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a parameter setting method, a mobile terminal and a computer readable storage medium. The parameter setting method of the mobile terminal is applied to the mobile terminal side and can be executed by the mobile terminal, and the mobile terminal provided by the embodiment of the invention comprises but is not limited to intelligent terminals such as mobile phones, tablet computers, computers and wearable equipment.
Fig. 1 is a schematic flow chart of a parameter setting method of a mobile terminal according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
s102, setting the maximum signal transmission power value of the mobile terminal as a first power value;
and S104, gradually reducing the first power value, and re-determining the maximum signal transmission power value of the mobile terminal according to the comparison result between the signal-to-noise ratio of the received signal corresponding to the first power value before reduction and the signal-to-noise ratio of the received signal corresponding to the first power value after reduction and the preset lower limit value of the transmission power.
In the embodiment of the invention, the maximum signal transmitting power value of the mobile terminal is set as a first power value, then the first power value is reduced gradually, and the maximum signal transmitting power value of the mobile terminal is determined again according to the comparison result between the signal-to-noise ratio of the received signal corresponding to the first power value before reduction and the signal-to-noise ratio of the received signal corresponding to the first power value after reduction and the preset lower limit value of the transmitting power. By the embodiment of the invention, the maximum signal transmitting power can be reduced gradually, and the maximum signal transmitting power is determined again based on the signal-to-noise ratio of the received signal and the preset transmitting power lower limit value, so that the interference of the signal transmitting process of the mobile terminal on the signal receiving process of the mobile terminal is relieved.
In the above steps S102 to S104, first, the maximum signal transmission power value of the mobile terminal is set as the first power value, the mobile terminal successively decreases the first power value, the comparison result between the signal-to-noise ratio of the received signal corresponding to the first power value before each decrease and the signal-to-noise ratio of the received signal corresponding to the first power value after each decrease, and the preset transmission power lower limit value, and the maximum signal transmission power value of the mobile terminal is determined again in the first power values before and after each decrease.
In this embodiment, the maximum signal transmission power value may be set according to a range allowed by the communication standard specification, that is, the maximum signal transmission power value may be greater than or equal to a lower limit value of the range allowed by the communication standard specification and less than or equal to an upper limit value of the range allowed by the communication standard specification. The preset lower limit of the transmission power may also be set according to a lower limit of a range allowed by the communication standard, for example, the preset lower limit of the transmission power is greater than or equal to the lower limit of the range allowed by the communication standard. The maximum signal transmission power value and the preset transmission power lower limit value may also be set according to the requirements of the actual mobile communication, which is not limited herein.
In this embodiment, decreasing the first power value may decrease the first power value according to a preset power decrease value. The preset power reduction value may be an equal value, for example, the power reduction value is 0.5dBm, the maximum signal transmission power is reduced by 0.5dBm each time, and the specific value is not limited here, or the power reduction value may also be an unequal value according to the actual requirement, for example, the power reduction value is reduced according to a certain rule, and the specific value is not limited here.
In this embodiment, after the first power value is reduced, the signal-to-noise ratio of the received signal may be improved, so that the signal-to-noise ratio of the received signal corresponding to the first power value before reduction at each time may be smaller than the signal-to-noise ratio of the received signal corresponding to the first power value after reduction at this time, and the signal-to-noise ratio of the received signal corresponding to the first power value after reduction is improved by reducing the first power value, thereby alleviating interference of a signal transmission process of the mobile terminal on a signal receiving process of the mobile terminal.
Further, in the embodiment of the present invention, re-determining the maximum signal transmission power value of the mobile terminal according to a comparison result between the signal-to-noise ratio of the received signal corresponding to the first power value before being reduced each time and the signal-to-noise ratio of the received signal corresponding to the first power value after being reduced each time, and a preset lower limit value of transmission power includes:
(a1) determining the signal-to-noise ratio of the received signal corresponding to the first power value before reduction each time as a first signal-to-noise ratio, and determining the signal-to-noise ratio of the received signal corresponding to the first power value after reduction each time as a second signal-to-noise ratio;
(a2) and if the difference between the second signal-to-noise ratio and the first signal-to-noise ratio is greater than or equal to zero and smaller than a preset difference threshold value, and the reduced first power value is not smaller than a preset lower transmission power limit value, re-determining the reduced first power value as the maximum signal transmission power value of the mobile terminal.
In the above action (a2), the preset difference threshold may be set to 2dB or 1dB, which is not limited herein.
In an embodiment, when the first power value after the first reduction is not less than the preset lower limit of the transmission power, and the difference between the corresponding second signal-to-noise ratio and the first signal-to-noise ratio after the first reduction of the first power value is equal to 1dB and less than the preset difference threshold 2dB, the step of reducing the first power value is stopped, and the reduced first power value is determined as the maximum signal transmission power value of the mobile terminal again.
Further, in the embodiment of the present invention, if the difference between the second snr and the first snr is greater than the preset difference threshold and the first power value after the reduction is not less than the preset lower limit of the transmission power, the step of reducing the first power value is repeatedly performed.
In this embodiment of the present invention, if the difference between the second snr and the first snr is greater than the preset difference threshold, and the first power value after the reduction is not less than the preset lower transmission power limit, the mobile terminal repeatedly performs the step of reducing the first power value until the difference between the second snr and the first snr is greater than or equal to zero and less than the preset difference threshold, and the first power value after the reduction is not less than the preset lower transmission power limit, and then determines the first power value after the reduction again as the maximum signal transmission power value of the mobile terminal.
In an embodiment, when the preset difference threshold is set to 2dB, the first power value after the mobile terminal is first reduced is greater than the preset lower limit of the transmission power, and at this time, the difference between the second signal-to-noise ratio and the first signal-to-noise ratio is 6dB, the first power value after the mobile terminal repeatedly performs the step of reducing the maximum signal transmission power in the mobile terminal for 6 times is greater than the preset lower limit of the transmission power, and the difference between the second signal-to-noise ratio and the first signal-to-noise ratio corresponding to the first power value being reduced for 6 times is 1dB, and the difference between the second signal-to-noise ratio and the first signal-to-noise ratio after the first power value is reduced is smaller than the preset difference threshold by 2dB, then the first power value after the 6 th reduction is determined as the maximum signal transmission. It can be seen that by repeatedly reducing the first power value in this embodiment, the signal-to-noise ratio can be maximally improved when the transmission power is not less than the preset lower limit value of the transmission power, so that the interference of the signal transmission process of the mobile terminal on the signal reception process of the mobile terminal can be alleviated.
Further, in the embodiment of the present invention, if the first power value after the reduction is smaller than the preset lower limit of the transmission power, the first power value before the reduction is determined as the maximum signal transmission power value of the mobile terminal again.
In an embodiment, when the power value obtained by first reducing the first power value is smaller than the preset lower limit of the transmission power and meets the condition that the reduced first power value is smaller than the preset lower limit of the transmission power, the first power value before the first reduction is selected as the maximum signal transmission power value of the mobile terminal.
In one embodiment, the communication standard specifies that the lower limit of the allowed maximum signal transmitting power is 20dBm, the first power value is set to be 25dBm, and the preset difference threshold between the second signal-to-noise ratio and the first signal-to-noise ratio is 0. When detecting that the signal transmitting power of the mobile terminal is 25dBm of the maximum signal transmitting power of the mobile terminal, acquiring that the first signal-to-noise ratio of a receiving signal corresponding to 25dBm of the maximum signal transmitting power before being reduced is 30dB, firstly reducing the maximum signal transmitting power according to a power reduction value of 0.5dBm, acquiring that the second signal-to-noise ratio of the receiving signal corresponding to the maximum signal transmitting power value after being reduced for the first time is 40dB, comparing the 40dB with the 30dB to obtain a comparison result which is larger than a difference threshold value, and the transmitting power value after the maximum signal transmitting power value is reduced for the first time by 25dBm is 24.5dBm which is larger than a lower limit value of the maximum signal transmitting power allowed by a communication standard by 20dBm, repeatedly reducing the maximum signal transmitting power value after being reduced for the previous time according to the power reduction value of 0.5dBm until the maximum signal transmitting power value obtained after the maximum signal transmitting power is reduced for the 6, the correspondingly reduced second signal-to-noise ratio is 50dB, the maximum power value obtained after the maximum signal transmitting power is reduced for 5 th time according to the power reduction value of 0.5dBm is 22.5dBm, the corresponding 5 th signal-to-noise ratio is 50dB, namely the corresponding second signal-to-noise ratio before the power is reduced for 6 th time is 50dB, the difference value between the second signal-to-noise ratio before and after the power is reduced for 6 th time and the first signal-to-noise ratio is equal to 0, and the corresponding maximum power value 22dBm after the power is reduced for 6 th time is larger than the maximum signal transmitting power lower limit value 20dBm allowed by the communication standard, the reduction of the maximum signal transmitting power is stopped, and the maximum signal transmitting power 22dBm after the power is reduced for 6 th time is selected as the maximum signal.
Fig. 2 is a schematic flow chart of a parameter setting method of a mobile terminal according to another embodiment of the present invention, as shown in fig. 2, the method includes the following steps:

if yes, executing S212, otherwise, executing S204;
s210, the first power value before reduction is determined as the maximum signal transmission power value of the mobile terminal again;
s212, re-determining the reduced first power value as the maximum signal transmission power value of the mobile terminal.
Furthermore, in the embodiment of the present invention, the maximum signal transmission power value after each reduction corresponds to a set of maximum signal transmission power parameters, and each set of maximum signal transmission power parameters is stored in the mobile terminal in advance. In the process of successively reducing the first power value, the maximum signal transmission power parameters of each group are collectively called power level parameters. And after the maximum signal transmission power value is determined again, the mobile terminal transmits signals according to the maximum signal transmission power parameter corresponding to the determined maximum signal transmission power value.
In this embodiment, during the process of successively reducing the first power value, the mobile terminal may respectively correspond to each set of maximum signal transmission power parameters through a certain corresponding relationship, where the corresponding relationship may be determined according to a certain functional relationship, and the maximum signal transmission power value after each reduction respectively corresponds to one set of maximum signal transmission power parameters, for example, the corresponding relationship between the maximum signal transmission power value Y and the maximum signal transmission power parameters a and b is Y ═ (a, b), and the mobile terminal stores each set of maximum signal transmission power parameters in the mobile terminal in advance.
In one embodiment, the mobile terminal may preset a parameter adjustment period, set a maximum signal transmission power value of the mobile terminal as a first power value in a current period, successively decrease the first power value by the mobile terminal, and reselect the maximum signal transmission power value in the current period of the mobile terminal from the first power values after each decrease according to a comparison result between a signal-to-noise ratio of a received signal corresponding to the first power value before each decrease and a signal-to-noise ratio of a received signal corresponding to the first power value after each decrease, and a preset lower limit value of transmission power.
In this embodiment, the preset parameter adjustment period may be set to 7 days, or may be 30 days, which is not limited herein. The mobile terminal realizes the processes of resetting the maximum signal transmitting power, reducing the maximum signal transmitting power and re-determining the maximum signal transmitting power in each period according to the set parameter adjusting period, can achieve the effect of timely relieving the interference of the signal transmitting process of the mobile terminal to the signal receiving process of the mobile terminal according to the interference change condition, and avoids the problems that the maximum signal transmitting power is still reduced after the interference is weakened and the maximum signal transmitting power is not further reduced after the interference is enhanced.
In the embodiment of the invention, the maximum signal transmitting power value of the mobile terminal is set as a first power value, then the first power value is reduced gradually, and the maximum signal transmitting power value of the mobile terminal is determined again according to the comparison result between the signal-to-noise ratio of the received signal corresponding to the first power value before reduction and the signal-to-noise ratio of the received signal corresponding to the first power value after reduction and the preset lower limit value of the transmitting power.
