Detailed Description

In order to solve the problem that the existing mode for reducing the power consumption of WIFI transmission cannot meet the data transmission requirement, an embodiment of the present invention provides a power adjustment method, which includes: acquiring a Received Signal Strength Indication (RSSI) value of Bluetooth (BT) connection between a first terminal and a second terminal; and under the condition that the RSSI value is greater than a first preset threshold value, the WIFI transmitting power of the first terminal for the second terminal is reduced. Therefore, the power consumption is reduced by reducing the WIFI transmitting power between the two terminals, and compared with the reduction of the transmitting times in the prior art, the transmission of corresponding data can be ensured, so that the data transmission requirement is met.

Further, in the embodiment of the present invention, the RSSI value of the BT connection between the two terminals is used as a reference index for reducing the WIFI transmission power, but the reason why the WIFI RSSI value is not used as the reference index for reducing the WIFI transmission power is: when the WIFI RSSI value is used as a reference index, the premise is that the transmission power of the AP device is fixed at a fixed transmission rate, and the terminal accessing the AP device can accurately determine that the transmission power is reduced, and can also stably transmit and maintain the highest transmission rate. For example, the AP device wants to reduce power consumption to save power, and thus reduces the transmission power from 15dBm to 0 dBm; at this time, the WIFI RSSI value of the terminal accessing the AP device becomes low (for example, from-50 dBm to-65 dBm originally), so that the terminal cannot turn down power. By adopting the scheme in the embodiment of the invention, the problem can be improved.

The condition of reducing power in the WIFI is that the signal is stable, so that the transmission distance of the WIFI at the moment cannot be too far, and good signal quality is kept. For example, referring to fig. 1, taking WIFI 2.4G 11N MCS7 as an example, within 20dB of attenuation, the signal (signal) quality of WIFI transmission is the best (at this time, WIFI RSSI > -60dBm), and the transmission rate of 11N MCS7 is the highest. Therefore, the operation of reducing the WIFI transmission power can be performed within 15dB of the attenuation (the range of use is about 10 m), and the operation of reducing the transmission power can be performed while maintaining the maximum transmission rate of 11N MCS7, while the RSSI obtained by the terminal is within-60 dBm.

Because the operating frequency of BT is 2.4G, overlaps with WIFI 2.4G working range, and BT has a frequency hopping mechanism, is less prone to be interfered by the outside than WIFI, therefore has certain referential, and can ensure the characteristic that BT can be connected within the range of adjustable power reduction of WIFI.

In addition, BT and WIFI are on the same antenna on many devices, so the RSSI of BT is more referential in WIFI. BT has the advantage of power savings, and BT power is generally lower than WIFI, and therefore more power savings.

The feasibility of this scheme is described below by comparing WIFI 2.4G 11N MCS7 with BT.

Specifically, the comparison between WIFI 2.4G 11N MCS7 and BT may include the following:

1) the power of the WIFI 2.4G 11N MCS7 generally falls within 8-16 dBm, and the receiving sensitivity generally falls within-65 dBm or lower. The power of BT at the basic rate (basic rate) generally falls between 8 and 13dBm, the receiving sensitivity generally falls between-88 dBm or lower, and therefore the coverage range is larger than the reduced power range of WIFI 2.4G 11N MCS 7.

2) The BT under the enhanced data rate (enhanced data rate) has the transmission power (Tx power) of about 8-13 dBm, the receiving sensitivity generally falls above-80 dBm, and the BT can also cover the power reduction range of WIFI 2.4G 11N MCS 7.

3) The BT and Tx power under low power consumption (low power) is less than 10dBm, the receiving sensitivity generally falls above-90 dBm, and the reduced power range of WIFI 2.4G 11N MCS7 can be covered. And compared with BT basic data and BTenhance data rate, the power is saved.

4) For BT use range around 10m, since the stable use range of WIFI 2.4G 11N MCS7 is within 10m, BT can completely cover the range of WIFI 2.4G 11N MCS7 to reduce power.

Further, since 11N MCS7 for WIFI 5G has a larger distance attenuation than 2.4G, BT can also cover the WIFI 5G attenuation range. Here, the WIFI 11N MCS7 is taken as an example, but power may be reduced for various data rates (data rates) of WIFI, for example, the power of 11N 54 mbps is about 14dBm, and the receiving sensitivity is about-74 dBm.

In addition, since WIFI can make power down for individual access terminals, on one hand, power saving can be ensured, and on the other hand, good downward compatibility can also be achieved.

Referring to fig. 2, fig. 2 is a flowchart of a power adjustment method according to an embodiment of the present invention, where the method is applied to a first terminal, and as shown in fig. 2, the method includes the following steps:

step 201: and acquiring the RSSI value of the BT connection between the first terminal and the second terminal.

Alternatively, the first terminal may be an AP device, and the second terminal is a terminal device connected to the AP device (i.e., the first terminal). Alternatively, the second terminal may be an AP device, and the first terminal is a terminal device connected to the AP device (i.e., the second terminal). Therefore, the AP equipment and the terminal equipment connected with the AP equipment can reduce the transmitting power of WIFI each other by using the RSSI value of BT connection as a basis so as to achieve the purpose of power saving.

Step 202: and under the condition that the RSSI value is greater than a first preset threshold value, the WIFI transmitting power of the first terminal for the second terminal is reduced.

Alternatively, the first preset threshold may be preset based on actual requirements, such as being preset to-60 dBm.

It can be understood that the RSSI value greater than the first predetermined threshold (e.g., -60dBm) indicates a better transmission quality between the first terminal and the second terminal. At this time, in order to reduce power consumption to save power, the first terminal may reduce its WIFI transmission power for the second terminal.

Optionally, if the RSSI value is greater than a first preset threshold, the first terminal may further send indication information to the second terminal; the indication information is used for indicating the second terminal to reduce the WIFI transmission power of the first terminal. Therefore, the second terminal can reduce the WIFI transmitting power of the second terminal under the condition that the transmission quality between the second terminal and the first terminal is good, so that the power consumption is reduced, and the power saving effect is achieved.

Optionally, after the RSSI value of the BT connection between the first terminal and the second terminal is obtained, the method further includes:

and keeping the WIFI transmission power of the first terminal for the second terminal unchanged under the condition that the RSSI value is less than or equal to a first preset threshold value. Thus, the transmission of the corresponding data can be ensured under the condition that the transmission quality between the first terminal and the second terminal is not good.

According to the power adjustment method provided by the embodiment of the invention, the RSSI value of the BT connection between the first terminal and the second terminal can be obtained, and the WIFI transmission power of the first terminal for the second terminal is reduced under the condition that the RSSI value is greater than the first preset threshold value. Therefore, the power consumption is reduced by reducing the WIFI transmitting power between the two terminals, and compared with the reduction of the transmitting times in the prior art, the transmission of corresponding data can be ensured, so that the data transmission requirement is met.

Optionally, when the obtained RSSI value is greater than a first preset threshold, the above process of reducing the WIFI transmission power of the first terminal for the second terminal may include:

acquiring a first packet error rate and a second packet error rate, wherein the first packet error rate is the packet error rate of WIFI transmission of a first terminal, and the second packet error rate is the packet error rate of WIFI transmission of a second terminal;

and under the condition that the first packet error rate is smaller than a second preset threshold value and the second packet error rate is smaller than a third preset threshold value, the WIFI transmitting power of the first terminal for the second terminal is reduced.

Therefore, the WIFI transmitting power of the first terminal for the second terminal can be reduced under the condition of further ensuring the WIFI transmission success rate, and accordingly transmission of corresponding data is ensured.

Optionally, the second preset threshold and the third preset threshold may be preset based on actual requirements, and may be the same or different. For example, the second preset threshold is 9%, and the third preset threshold is 10%; alternatively, the second preset threshold and the third preset threshold are both 10%.

In one embodiment, the process of obtaining the first packet error rate may be: the first terminal sends the packets to the second terminal by means of WIFI, and whether all the packets of the second terminal can be analyzed is confirmed; if there is a packet that can not be parsed, the second terminal may request the first terminal to retransmit the packet; based on the retransmitted packet, the first terminal can calculate the packet error rate of the WIFI transmission and inform the second terminal of the packet error rate.

In another embodiment, the process of obtaining the second packet error rate may be: the second terminal sends the packets to the first terminal by means of WIFI, and whether all the packets of the first terminal can be analyzed is confirmed; if there is a packet that can not be parsed, the first terminal may request the second terminal to retransmit the packet; based on the retransmitted packet, the second terminal can calculate the packet error rate of the WIFI transmission and inform the first terminal of the packet error rate.

Next, a power adjustment process according to an embodiment of the present invention will be described with reference to fig. 3.

As shown in fig. 3, the corresponding power adjustment procedure may include:

step 31: the WIFI AP of the handheld device is started (subsequently called AP equipment), and the BT function is started at the same time.

Step 32: the terminal device (such as a handset) is connected to the AP device. At this time, the AP device may send inquiry information to the terminal device, for inquiring whether the terminal device is to connect to the BT, so as to start the BT-based WIFI AP power saving mode.

Step 33: the terminal equipment confirms whether the BT is connected or not so as to start a WIFI AP power saving mode based on the BT.

Step 34: if the terminal device is not connected with the BT of the AP device, the AP device does not use a power down regulation mode based on the BT RSSI value (i.e., the RSSI value of the BT connection) for the terminal device, i.e., does not use the BT RSSI value to reduce the WIFI transmission power.

It can be understood that the reason why the terminal device is not connected with the BT may be that the terminal device does not have the BT function, or that the terminal device is too far away from the AP device to connect with the BT. At this time, the AP device may not reduce the WIFI transmit power (use the normal mode); and the terminal device may adjust the WIFI transmission power in a predefined manner (e.g., adjust the WIFI transmission power by using the WIFI RSSI value) or not adjust the WIFI transmission power.

Step 35: if the terminal device opens the BT function and connects the BT of the AP device, the AP device determines whether the BT RSSI value with the terminal device meets a determination criterion, such as whether the BT RSSI value with the terminal device is greater than-60 dBm.

Step 36: if the BT RSSI value is judged to be smaller than or equal to-60 dBm, the AP equipment does not adopt a power adjustment and reduction mode based on the BT RSSI value aiming at the terminal equipment, namely the BT RSSI value is not used for reducing the WIFI transmitting power.

At this time, the AP device may not reduce the WIFI transmit power (use the normal mode). And the terminal equipment does not adopt a power regulation and reduction mode based on the BT RSSI value aiming at the AP equipment, namely, the BT RSSI value is not used for reducing the WIFI transmission power.

Step 37: if the BT RSSI value is greater than-60 dBm, the AP device determines whether the WIFI packet error rate is sufficient, for example, determines whether a packet error rate 1 of WIFI transmission of the AP device is less than 10%, and determines whether a packet error rate 2 of WIFI transmission of the terminal device is less than 10%.

For example, the procedure for obtaining the packet error rate 1 may be: the AP equipment sends the packets to the terminal equipment by virtue of WIFI, and confirms whether all the packets of the terminal equipment can be analyzed; if there is a packet that can not be analyzed, the terminal device may request the AP device to retransmit the packet; based on the retransmitted packet, the AP device may calculate a packet error rate 1 of the WIFI transmission, and may notify the terminal device of the packet error rate 1.

For another example, the packet error rate 2 may be obtained by: the terminal equipment sends the packets to the AP equipment by virtue of WIFI, and confirms whether all the packets of the AP equipment can be analyzed; if there is a packet that can not be analyzed, the AP device may request the terminal device to retransmit the packet; based on the retransmitted packet, the terminal device can calculate the packet error rate 2 of the WIFI transmission and inform the AP device of the packet error rate.

Step 38: if the packet error rate 1 and the packet error rate 2 are not both less than 10%, for example, the packet error rate 1 and/or the packet error rate 2 is greater than 10%, the AP device does not adopt a power down regulation mode based on the BT RSSI value for the terminal device, that is, does not use the BTRSSI value to reduce the WIFI transmission power.

At this time, the AP device may not reduce the WIFI transmit power (use the normal mode). The terminal device does not adopt a power adjustment and reduction mode based on the BT RSSI value for the AP device, but may adjust and reduce the WIFI transmission power in a predefined mode (for example, adjust and reduce the WIFI transmission power by the WIFI RSSI value) or not adjust and reduce the WIFI transmission power.

Step 39: if the packet error rate 1 and the packet error rate 2 are both smaller than 10%, the AP device starts a corresponding power down regulation mode, that is, a BT RSSI value-based power down regulation mode is adopted for the terminal device, and the BT RSSI value is used to reduce the WIFI transmission power.

Optionally, in the process of step 39, the AP device may transmit indication information to the terminal device via the WIFI, so as to indicate that a BT RSSI value-based power down regulation mode may be adopted. And after the terminal equipment receives the indication information, the terminal equipment can perform one of the following operations:

if the terminal equipment supports a power adjustment and reduction mode based on the BT RSSI value, the BT RSSI value is used for reducing the WIFI transmission power aiming at the AP equipment;

if the terminal device does not support the BT RSSI value based power reduction adjustment mode, the predefined mode is used to reduce the WIFI transmission power (for example, the WIFI transmission power is reduced by the WIFI RSSI value) or the WIFI transmission power is not reduced.

It should be noted that, no matter whether a BT RSSI value based power down regulation mode can be adopted, the AP device may continuously monitor the BT RSSI value and determine whether the power down regulation standard is satisfied, thereby determining whether to continuously reduce the WIFI transmission power. The BT RSSI value-based power reduction regulation mode can be applied to high data rate (high data rate) situations of WIFI protocols such as 2.4G 11B/G/N or 5G A/N/AC.

Next, the power adjustment in the specific example is described with reference to scenarios one to three.

Scene one

As shown in fig. 4, the handheld device is used as a WIFI AP, and has adjustable power and an operating frequency of 2.4G. At this time, if the WIFI AP and the terminal device 1 (which may be abbreviated as user1) both have the BT function, after the terminal device 1 connects to the WIFI AP, BT connection may be started simultaneously by using software. At this time, the WIFI AP and the terminal device 1 may determine whether power can be reduced by receiving BT RSSI values from each other.

For example, if the BT RSSI value of the terminal device 1 received by the WIFI AP is greater than-60 dBm, and the WIFI AP and the WIFI PER (Packet Error Rate) of the terminal device 1 both meet the condition, the WIFI power adjustment and reduction mechanism is started, if the WIFI AP uses the BT RSSI value to reduce the WIFI transmission power for the terminal device 1, and the terminal device 1 uses the BT RSSI value to reduce the WIFI transmission power for the WIFI AP at the same time; for example, from 15dBm originally, to 0 dBm.

Meanwhile, the WIFI AP is WIFI-connected to another device (e.g. terminal device 2, which may be abbreviated as user2), and BT connection is started. At this time, if the BT RSSI value of the terminal device 2 received by the WIFI AP is less than-60 dBm, the power down-regulation mode based on the BTRSSI value is not adopted. For example, the WIFI AP may maintain the WIFI power of the terminal device 2 at 15dBm, and the terminal device 2 may adjust the WIFI transmit power or not adjust the WIFI transmit power in a predefined manner (e.g., the WIFI transmit power is maintained at 15 dBm).

Therefore, when the handheld device is used as a WIFI AP, the size of WIFI transmitting power can be adjusted according to different users (namely different terminal equipment) and different distances from the users, so that power is properly saved, and stable transmission rate is ensured.

Scene two

As shown in fig. 5, the handheld device is used as a WIFI AP, and has adjustable power and an operating frequency of 2.4G. At this time, if the WIFI AP and the terminal device 3 (which may be abbreviated as user3) both have the BT function, after the terminal device 3 connects to the WIFI AP, BT connection may be started simultaneously by using software. However, if the terminal device 3 does not have the function of adjusting and reducing the WIFI power, when the BT RSSI value of the terminal device 3 received by the WIFI AP is greater than-60 dBm and both the WIFI AP and the WIFI PER of the terminal device 3 meet the condition, only the WIFI AP may use the BT RSSI value to reduce the WIFI transmit power for the terminal device 3, for example, reduce the WIFI transmit power from 15dBm to 0 dBm. While the terminal device 3 maintains the WIFI transmit power (e.g., 15dBm) unchanged.

Meanwhile, the WIFI AP is WIFI-connected to another device (e.g. terminal device 4, which may be abbreviated as user 4). However, if the terminal device 4 does not have the BT function or is too far away from the WIFI AP to BT connect, the BTRSSI value cannot be used to reduce the WIFI transmission power. For example, the WIFI AP may maintain the WIFI transmit power (e.g., 15dBm) for the terminal device 4; the terminal device 5 may use a predefined manner to adjust or not decrease the WIFI transmit power (e.g., maintain the WIFI transmit power at 15dBm), and maintain good downward compatibility.

Scene three

As shown in fig. 6, the handheld device is used as a WIFI AP, and has adjustable power and an operating frequency of 2.4G. At this time, if the WIFI AP does not support the BT RSSI value based power down mode for the connected terminal device 5 (which may be abbreviated as user5), or cannot connect with the BT because the terminal device 5 does not turn on the BT function, even if the BT RSSI value of the terminal device 5 received by the WIFI AP is greater than-60 dBm, the WIFI AP does not adopt the BT RSSI value based power down mode for the terminal device 5, and for example, the WIFI transmission power (for example, 15dBm) is maintained. The terminal device 5 may use a predefined manner to adjust the WIFI transmission power (e.g., from originally 15dBm to 0dBm) or not to adjust the WIFI transmission power, so as to maintain good downward compatibility.

The above results show that: when the BT RSSI value is used for judging whether the WIFI transmitting power of the WIFI AP and the terminal equipment can be adjusted and reduced, under the condition of maintaining stable and high transmission rate, the terminal equipment can also achieve a power saving mode in addition to the WIFI transmitting power which can be adjusted and reduced by the WIFI AP, and the power adjusting and reducing mode based on the BT RSSI value can be downward compatible without influencing the use experience.

In addition, for applications such as existing mutual transmission software, when two user terminals transmit data, the data are mainly transmitted based on a WIFI connection or transmitted based on a BT connection. If WIFI (for example, 11AC MCS9, bandwidth 80MHz) is the main transmission path, the BT RSSI value is used as the basis to adjust the WIFI transmission power, so as to reduce the power transmitted between them, thereby achieving the effect of saving power while maintaining the transmission rate at the highest state.

Further, the memory 809 can include high speed random access memory, and can also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The processor 810 is a control center of the terminal, connects various parts of the entire terminal using various interfaces and lines, and performs various functions of the terminal and processes data by operating or executing software programs and/or modules stored in the memory 809 and calling data stored in the memory 809, thereby integrally monitoring the terminal. Processor 810 may include one or more processing units; preferably, the processor 810 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 810.

The terminal 800 may also include a power supply 811 (e.g., a battery) for powering the various components, and preferably, the power supply 811 may be logically coupled to the processor 810 via a power management system to provide management of charging, discharging, and power consumption via the power management system.

In addition, the terminal 800 may further include some functional modules that are not shown, and are not described herein again.
