With the development of technology and the continuous improvement of living standard of people, the use of various electronic devices (such as mobile phones, computers, etc.) is becoming more and more popular.

Embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 2, the power adjustment method provided by the present application is applied to an electronic device, and the method includes:
s110: and acquiring target signal strength, wherein the target signal strength is the strength of a wireless signal received by the electronic equipment, and the wireless signal is sent by network access equipment.
In one manner, the electronic device may obtain the target signal strength through RSSI (Received Signal Strength Indication ). Alternatively, the electronic device may directly use the RSSI calculated from the wireless signal transmitted by the network access device as the target signal strength.
Alternatively, the wireless signal may be a Wi-Fi (Wireless Fidelity ) signal and the network access device may be an AP (e.g., router, etc.).
As one approach, the electronic device may obtain the target signal strength from a network module in the electronic device. Alternatively, the electronic device may periodically acquire the target signal strength.
In the embodiment of the application, the electronic equipment can acquire a plurality of target signal intensities generated by the network access equipment in a specified time period. For example, the designated period of time may be 1 minute, and the electronic device may acquire the target signal strength every 1 second, at this time, the electronic device may set a counter with a value of 60, decrease the value of the counter by 1 every 1 second, and store the target signal strength in an array, and when the value of the counter is 0, the target signal strength is not continuously acquired, so that the target signal strength within 1 minute is acquired as a plurality of target signal strengths.
Alternatively, the specified time period may be determined based on a complexity of a communication environment to which the electronic device corresponds. As one approach, the electronic device may determine the network complexity based on the number of network access devices that can be searched. If the number of network access devices in the space where the electronic device is located is larger than a preset value, determining that the communication environment corresponding to the electronic device is complex, and setting the designated time period as a first designated time period; if the number of network access devices in the space where the electronic device is located does not exceed the preset value, it can be determined that the communication environment corresponding to the electronic device is simple, and the specified time period is set to be the second specified time period, where the first specified time period is smaller than the second specified time period, so that when the communication environment is complex, the frequency of power adjustment can be increased, and the transmitting power of the electronic device can be adapted to the complex communication environment more quickly. For example, the first specified time period may be 1 minute, the second specified time period may be 5 minutes, and if it is determined that the communication environment corresponding to the electronic device is complex, the specified time period may be set to 1 minute, that is, the transmit power may be adjusted every 1 minute; if it is determined that the communication environment corresponding to the electronic device is simple, the specified period of time may be set to 5 minutes, that is, the transmission power may be adjusted every 5 minutes.
Optionally, in the embodiment of the present application, the complexity of the communication environment corresponding to the electronic device may also be determined based on the number of network access devices having the same signal frequency band as the network access device connected to the electronic device in the space where the electronic device is located. If the number of network access devices with the same signal frequency band is larger than a preset value in the space where the electronic device is located, the complexity of the communication environment corresponding to the electronic device can be determined. Otherwise, the communication environment corresponding to the electronic equipment is determined to be simple. The network access device with the same signal frequency band can be understood that the carrier frequency band corresponding to the wireless signal transmitted by the network access device connected with the electronic device is the same as the carrier frequency band corresponding to the wireless signal transmitted by the network access device.
Alternatively, a preset number of target signal strengths generated within a specified period of time may be obtained. When the electronic device periodically acquires the target signal intensities, if the time length corresponding to the specified time period exceeds a preset value, a preset number of target signal intensities may be acquired, where the preset number may be less than or equal to the total number of target signal intensities acquired by the electronic device in the specified time period. In this case, a predetermined number of target signal strengths may be acquired from all target signal strengths acquired within a specified period of time by means of random sampling or at a predetermined sampling frequency. The preset sampling frequency may be less than or equal to a log reporting frequency of the network access device.
In the embodiment of the application, the preset number of the target signal intensities generated in the specified time period are acquired, so that when the acquired target signal intensities in the specified time period are more, the acquired target signal intensities can be further screened, the data is simplified, and the subsequent calculation efficiency is improved.
S120: and if the electronic equipment is in a communication stable state based on the target signal strength, acquiring the current negotiation rate of the electronic equipment and reducing the transmitting power of the electronic equipment, wherein the current negotiation rate characterizes the communication rate currently used by the electronic equipment and the network access equipment.
The communication stable state of the electronic device may be a state that a distance between the electronic device and the network access device is relatively stable, the magnitude of the target signal strength may be inversely related to the distance between the electronic device and the network access device, and a calculation formula between the target strength and the distance may be:
the RSSI may be a target signal strength, n may represent an attenuation factor, a may represent a signal strength when the transmitting end and the receiving end are separated by 1 meter, and n and a may be empirical values obtained through multiple experiments.
As one way, it may be determined whether a distance between the electronic device and the network access device is relatively stable based on a plurality of target signal strengths within a specified period of time, and thus it may be determined whether the electronic device is in a communication stable state.
Optionally, the electronic device may acquire a maximum target signal strength and a minimum target signal strength corresponding to the plurality of target signal strengths in the specified time period, and if the difference between the maximum target signal strength and the minimum target signal strength is smaller than the preset difference, determine that the electronic device is in a communication stable state. The preset difference value may be an empirical value obtained according to a plurality of tests. For example, the plurality of target signal strengths over the specified time period may include: x1, x2, x3...xn, the maximum target signal strength may be x3, the minimum target signal strength may be x1, the difference between the maximum target signal strength and the minimum target signal strength may be a (x 3-x 1), the preset difference may be B, and if a < B, it may be determined that the electronic device is in a communication steady state; if A is more than or equal to B, the electronic equipment can be determined to be in a communication unstable state.
Optionally, the electronic device may obtain variances corresponding to the multiple target signal intensities in the specified time period, and if the variances are smaller than a preset variance, determine that the electronic device is in a communication steady state. The preset variance may be an empirical value obtained from multiple tests. For example, the plurality of target signal strengths over the specified time period may include: x1, x2, x3...xn, the variance corresponding to the plurality of target signal strengths may be C, the preset variance may be D, and if C < D, it may be determined that the electronic device is in a communication steady state; if C is more than or equal to D, the electronic equipment can be determined to be in a communication unstable state.
In one manner, if it is determined that the electronic device is in a communication steady state based on the target signal strength, the electronic device may perform negotiation of a communication rate with the network access device, and take the negotiated communication rate as a current negotiation rate, and take the current negotiation rate as the current negotiation rate of the electronic device, and reduce the transmission power of the electronic device. The transmit Power of the electronic device may refer to a transmit Power of a Power Amplifier (PA) of the electronic device.
In the embodiment of the present application, if it is determined that the electronic device is in the unstable communication state based on the target signal strength, the electronic device may delete the currently acquired target signal strength and re-execute step S110 to acquire a new target signal strength.
S130: and acquiring a reference negotiation rate, wherein the reference negotiation rate is the negotiation rate between the electronic equipment and the network access equipment after the transmitting power of the electronic equipment is reduced.
As one way, the electronic device may perform negotiation of the communication rate with the network access device again after reducing the transmission power of the PA, and use the negotiated communication rate as the reference negotiation rate.
S140: and if the reference negotiation rate is the same as the current negotiation rate, controlling the transmitting power of the electronic equipment to be high as the current transmitting power.
The current transmission power may refer to the transmission power after the electronic device performs the operation of reducing the transmission power in step S120.
As a way, the reference negotiation rate obtained based on step S130 may be compared with the current negotiation rate obtained based on step S120, and if the reference negotiation rate is the same as the current negotiation rate, the transmission power of the electronic device is controlled to be high as the current transmission power.
According to the power adjustment method provided by the embodiment, after the target strength representing the strength of the wireless signal received by the electronic equipment and sent by the network access equipment is obtained, if the electronic equipment is in a communication stable state based on the target signal strength, the current negotiation rate representing the communication rate currently used by the electronic equipment and the network access equipment is obtained, the transmitting power of the electronic equipment is reduced, the reference negotiation rate representing the negotiation rate between the electronic equipment and the network access equipment after the transmitting power is reduced is obtained, and if the reference negotiation rate is the same as the current negotiation rate, the transmitting power of the electronic equipment is controlled to be high as the current transmitting power. Therefore, under the condition that the electronic equipment is in a stable communication state, the current negotiation rate can be obtained and the transmission power of the electronic equipment is tried to be reduced, and further under the condition that the communication rate with the network access equipment is still the current negotiation rate before the transmission power is reduced after the transmission power is tried to be reduced, the transmission power of the electronic equipment is controlled to be high to be the current transmission power, and further the transmission power of the electronic equipment is reduced under the condition that the communication rate is not reduced, so that the power consumption of the electronic equipment is reduced.
Referring to fig. 3, the power adjustment method provided by the present application is applied to an electronic device, and the method includes:
s210: and acquiring target signal strength, wherein the target signal strength is the strength of a wireless signal received by the electronic equipment, and the wireless signal is sent by network access equipment.
As one approach, the electronic device may acquire the target signal strength in real time.
S220: and entering a current transmitting power adjustment process, acquiring the current negotiation rate of the electronic equipment and reducing the transmitting power of the electronic equipment.
In the embodiment of the application, in order to reduce the power consumption of the electronic device as much as possible under the condition of keeping the negotiation rate unchanged, the transmission power of the electronic device can be tried to be reduced based on the power reduction amplitude for a plurality of times.
In the embodiment of the application, the reducing amplitude in reducing the transmitting power of the electronic equipment can be determined in various ways.
As one way, the reduction amplitude may be configured by a developer default.
Alternatively, the power reduction amplitude may be determined based on a distance between the electronic device and the network access device, and the transmit power of the electronic device may be reduced based on the power reduction amplitude. Wherein, the closer the distance between the electronic device and the network access device is, the larger the power reduction amplitude is.
Alternatively, the distance between the electronic device and the network access device may be divided into a plurality of distance ranges, each distance range corresponding to one power reduction amplitude. And, the distance length of each distance range may be different, and the distance length may be determined based on the sensitivity degree of the negotiation rate to the change of the transmission power in the current distance range, and the higher the sensitivity degree, the smaller the corresponding distance length. By way of example, the maximum distance covered by the network access device signal may be 10 meters, which may be divided into 6 distance ranges: 0 to 1 meter, 1 to 3 meters, 3 to 6 meters, 6 to 8 meters, 8 to 9 meters, 9 to 10 meters, the power reduction amplitude corresponding to the 6 distance ranges can be: 4dBm, 3dBm, 2dBm, 1.5dBm, 1dBm, 0.5dBm.
In the embodiment of the application, the intelligent degree of the power adjustment method provided by the application can be improved by determining the power reduction amplitude based on the distance between the electronic equipment and the network access equipment, so that the transmitting power can be reduced rapidly when the distance is relatively close; when the distance is far, the transmitting power can be finely adjusted, and the power is reduced as much as possible.
S230: and acquiring a reference negotiation rate, wherein the reference negotiation rate is the negotiation rate between the electronic equipment and the network access equipment after the transmitting power of the electronic equipment is reduced.
S240: if the reference negotiation rate is the same as the current negotiation rate of the current transmission power adjustment process, entering the next transmission power adjustment process.
As one way, if the reference negotiation rate is the same as the current negotiation rate of the current transmission power adjustment process, the reference negotiation rate may be used as the current rate of the next transmission power adjustment process, and the next transmission power adjustment process may be entered from step S220.
S250: and if the reference negotiation rate is smaller than the current negotiation rate, increasing the transmitting power of the electronic equipment.
As one way, if the reference negotiation rate is less than the current negotiation rate of the current transmit power adjustment procedure, the transmit power of the electronic device may be increased based on the power increase magnitude. Wherein the power increase amplitude is equal to the power decrease amplitude of step S220.
According to the power adjustment method provided by the embodiment, under the condition that the electronic equipment is in a communication stable state, the current negotiation rate can be obtained and the transmission power of the electronic equipment is tried to be reduced, and further under the condition that the communication rate with the network access equipment is still the current negotiation rate before the transmission power is reduced after the transmission power is tried to be reduced, the transmission power of the electronic equipment is controlled to be high to the current transmission power, and further the transmission power of the electronic equipment is reduced under the condition that the communication rate is not reduced, so that the power consumption of the electronic equipment is reduced. In addition, in the embodiment, the electronic device can acquire the target signal strength in real time, and dynamically adjust the transmitting power in real time under the condition that the electronic device is in a stable communication state, so that the transmitting power of the electronic device can be reduced as much as possible under the condition that the negotiation rate is unchanged, and the power consumption of the electronic device is reduced.
In order to better understand the schemes of all the embodiments of the present application, a business process of the power adjustment method of the present application is described below.
Referring to fig. 4, the electronic device may acquire a plurality of target signal strengths within a specified period, and if it is determined that the electronic device is in a communication unstable state based on the plurality of signal strengths, the acquired plurality of target signal strengths may be cleared and the plurality of target signal strengths within the specified period may be reacquired. If the electronic equipment is in a communication stable state based on the plurality of signal intensities, the current negotiation rate of the electronic equipment can be acquired, and the current negotiation rate is recorded as rate0; and reducing the transmitting power of the electronic equipment based on the power reduction amplitude, and acquiring the reference negotiation rate1 after the transmitting power is reduced.
After the rate1 and the rate0 are obtained, whether the rate1 is equal to the rate0 or not can be compared, if so, the negotiation rate can be kept unchanged after the transmission power is reduced, that is, the data transmission process between the electronic equipment and the network access equipment is not affected, that is, the transmission power of the electronic equipment possibly has a reduced space, and in order to reduce the power consumption of the electronic equipment as much as possible, the transmission power of the electronic equipment can be reduced again based on the power reduction amplitude; if not equal (rate 1< rate 0), it indicates that after the transmission power is reduced, the negotiation rate is reduced, and the reduced negotiation rate may cause a reduction in the data transmission rate between the electronic device and the network access device, or even may not perform data transmission, which indicates that the transmission power of the electronic device may have been reduced below the limit value at the current negotiation rate (rate 0), so that the transmission power of the electronic device may be increased based on the power increase amplitude, where the power increase amplitude is equal to the power decrease amplitude, so as to restore the transmission power of the electronic device to the limit value at the current negotiation rate (rate 0).
Optionally, each time the negotiation rate before and after the transmission power is reduced is compared, the negotiation rate after the transmission power is reduced at this time may be compared with the rate0, or may be compared with the rate1 in the previous comparison process.
For example, in the case that it is determined that the electronic device is in a communication steady state based on the plurality of signal strengths, the current negotiation rate (rate 0) of the electronic device may be 16Mbps, the minimum transmission power of the electronic device corresponding to the current negotiation rate may be 18dBm, the current transmission power corresponding to the current negotiation rate (rate 0) may be 20dBm, the power reduction amplitude and the power increase amplitude may be 1dBm, the transmission power may be reduced to 19dBm based on the power reduction amplitude, and the reference negotiation rate (rate 1) may be acquired to be 16Mbps; the transmit power can continue to be reduced to 18dBm and the reference negotiation rate (rate 1) at that time is obtained to be still 16Mbps; the transmit power can continue to be reduced to 18dBm and the reference negotiation rate (rate 1) at that time is obtained to be still 16Mbps; the transmit power may continue to be reduced to 17dBm and the reference negotiation rate (rate 1) obtained at that time may begin to be less than 16Mbps, indicating that the transmit power of the electronic device is reduced too much, and the transmit power may be increased back to 18dBm based on the power increase magnitude to maintain the negotiation rate of the electronic device at 16Mbps. As can be seen from fig. 5, when the emission power of the electronic device is above 19dBm, the current can be reduced by 15mA every time the emission power of 1dBm is reduced, and for a 2 x 2mimo (Multiple Input Multiple Output ) electronic device, the overall current of 30mA can be reduced by 1dBm, so as to reduce the power consumption and save the electric quantity.
