Detailed Description

In order to solve the problem that the existing manner of reducing the power consumption of WIFI transmission cannot meet the data transmission requirement, the embodiment of the invention provides a power adjustment method, which includes: acquiring a received signal strength indication (Received Signal Strength Indication, RSSI) value of a Bluetooth (BT) connection between a first terminal and a second terminal; and under the condition that the RSSI value is larger than a first preset threshold value, reducing the WIFI transmitting power of the first terminal to the second terminal. 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 reason why the RSSI value of the BT connection between two terminals is used as the reference index for reducing the WIFI transmit power, instead of using the WIFI RSSI value as the reference index for reducing the WIFI transmit power is: when the WIFI RSSI value is used as a reference index, the premise is that the transmitting power of the AP equipment is fixed at a fixed transmission rate, and the terminal accessed to the AP equipment can accurately judge that the transmission can be stabilized and maintain the highest transmission rate under the condition of reducing the transmitting power. For example, an AP device wants to reduce power consumption to save power, thus reducing transmit power from the original 15dBm to 0dBm; at this time, the WIFI RSSI value of the terminal accessing the AP device becomes low (e.g., from-50 dBm to-65 dBm), which results in the terminal failing to reduce the power. By adopting the scheme of the embodiment of the invention, the problem can be improved.

The condition of WIFI power reduction is that signals are stable, so that the WIFI transmission distance cannot be too far at the moment, and good signal quality is kept. For example, as shown in fig. 1, taking WIFI 2.4g 11n MCS7 as an example, within 20dB of attenuation, the signal (signal) quality of WIFI transmission is best (WIFI RSSI > -60dBm at this time), and the transmission rate of 11n MCS7 is highest. Therefore, the operation of reducing the WIFI transmission power can be performed within 15dB of the attenuation (the use range is about 10 m), the RSSI obtained by the terminal is within-60 dBm, and the operation of reducing the transmission power can be performed, and the highest transmission rate of 11N MC S7 can be maintained.

The working frequency of the BT is 2.4G, the BT overlaps with the working range of the WIFI 2.4G, and the BT is provided with a frequency hopping mechanism and is less susceptible to external interference than the WIFI, so that the BT has certain referential property, and the BT can be connected with the WIFI in the range of adjustable power reduction.

In addition, on many devices, BT and WIFI are on the same antenna, so WIFI has a better reference according to the RSSI of BT. BT has the advantage of saving power, and BT power is typically lower than WIFI, thus saving more power.

Next, the feasibility of the scheme is described by comparing WIFI 2.4g11n MCS7 with BT.

Specifically, the comparison of WIFI 2.4g11n MCS7 and BT may include the following:

1) The power of WIFI 2.4g11n MCS7 typically falls between 8 and 16dBm, and the receive sensitivity typically falls at-65 dBm or lower. Whereas BT power at the basic rate typically falls between 8 and 13dBm, and receive sensitivity typically falls at-88 dBm or lower, thus covering a range greater than the reduced power range of WIFI 2.4g 11n MCS7.

2) BT at enhanced data rate (enhance data rate), transmit power (Tx power) is approximately 8-13 dBm, receive sensitivity typically falls above-80 dBm, and may cover the reduced power range of WIFI 2.4g 11n MCS7.

3) BT with low power consumption (Tx power is smaller than 10 dBm), and the receiving sensitivity is generally above-90 dBm, and the reduced power range of WIFI 2.4G 11N MC S7 can be covered. And is more power efficient than BT basic data and BT enhance data rate.

4) For the BT use range of about 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 power reduction.

In addition, for the 11n MCS7 of WIFI 5G, the BT can also cover the WIFI 5G attenuation range because the distance attenuation is greater than 2.4G. Although WIFI 11n MCS7 is taken as an example, the power may be adjusted for various data rates (data rates) of WIFI, for example, 11n 54mpbs power is about 14dBm, and the receiving sensitivity is about-74 dBm.

In addition, because WIFI can be aimed at individual access terminals and power is reduced, on the one hand, power saving can be ensured, and on the other hand, good downward compatibility can be achieved conveniently.

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, as shown in fig. 2, and the method includes the following steps:

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

Alternatively, the first terminal may be an AP device, and the second terminal may be 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 transmission power of WIFI by using the RSSI value of BT connection as the basis, so as to achieve the purpose of saving electricity.

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

Alternatively, the first preset threshold may be preset based on actual requirements, for example, may be preset to-60 dBm.

It is understood that when the RSSI value is greater than a first preset threshold (e.g., -60 dBm), it may indicate that the transmission quality between the first terminal and the second terminal is better. In order to reduce power consumption to save power at this time, the first terminal may reduce its WIFI transmit 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 transmitting power to the first terminal. Therefore, the WIFI transmitting power of the second terminal can be reduced 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 effect of saving electricity is achieved.

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

and under the condition that the RSSI value is smaller than or equal to a first preset threshold value, keeping the WIFI transmitting power of the first terminal aiming at the second terminal unchanged. In this way, 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 BT connection between the first terminal and the second terminal can be obtained, and the WIFI transmitting power of the first terminal for the second terminal is reduced under the condition that the RSSI value is larger 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, in the case that the acquired RSSI value is greater than the first preset threshold, the process of reducing the WIFI transmit 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 when 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, reducing the WIFI transmitting power of the first terminal to the second terminal.

Therefore, the WIFI transmitting power of the first terminal to the second terminal can be reduced under the condition of further ensuring the WIFI transmitting success rate, and accordingly the 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 an embodiment, the process of obtaining the first packet error rate may be: the first terminal sends a packet to the second terminal by means of WIFI, and confirms whether all packets of the second terminal can be analyzed; if there is a packet and there is no way to parse, the second terminal can request the first terminal to retransmit the packet; based on the retransmitted packet, the first terminal may calculate a packet error rate of its WIFI transmission, and may 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 packet to the first terminal by means of WIFI, and confirms whether all the packets of the first terminal can be analyzed; if there is a packet and there is no way to parse, the first terminal can request the second terminal to retransmit the packet; based on the retransmitted packet, the second terminal may calculate a packet error rate of its WIFI transmission, and may inform the first terminal of the packet error rate.

Next, a power adjustment process according to a specific example 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 handheld device WIFI AP is turned on (hereinafter referred to as AP device) while the BT function is started.

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

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

Step 34: if the terminal device does not connect with the BT of the AP device, the AP device does not adopt a power-down 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 transmit power.

It can be appreciated that, for reasons that the terminal device is not connected to BT, the terminal device may have no BT function, or the terminal device may be too far away from the AP device, resulting in BT connection failure. At this time, the AP device may not reduce WIFI transmit power (using normal mode); the terminal device may use a predefined manner to reduce the WIFI transmit power (e.g., reduce the WIFI transmit power by the WIFI RSSI value) or not reduce the WIFI transmit power.

Step 35: if the terminal device turns on the BT function and connects with 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 determining whether the BT RSSI value with the terminal device is greater than-60 dBm.

Step 36: if the BT RSSI value is less than or equal to-60 dBm, the AP equipment does not adopt a power-down mode based on the BT RSSI value for the terminal equipment, namely does not use the BT RSSI value to reduce the WIFI transmitting power.

At this time, the AP device may not reduce WIFI transmit power (using normal mode). The terminal equipment does not adopt a BT RSSI value-based power-down mode aiming at the AP equipment, namely does not use the BT RSSI value to reduce the WIFI transmitting 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 the packet error rate 1 of the WIFI transmission of the AP device is less than 10%, and determines whether the packet error rate 2 of the WIFI transmission of the terminal device is less than 10%.

For example, the packet error rate 1 may be obtained by: the AP equipment sends the packet to the terminal equipment by means of WIFI, and confirms whether all the packets of the terminal equipment can be analyzed; if the packet is not analyzed, the terminal equipment can request the AP equipment to retransmit the packet; based on the retransmitted packet, the AP device may calculate a packet error rate 1 of its WIFI transmission, and may inform 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 packet to the AP equipment by means of WIFI, and confirms whether all the packets of the AP equipment can be analyzed; if the packet is not analyzed, the AP equipment can request the terminal equipment to retransmit the packet; based on the retransmitted packet, the terminal device may calculate a packet error rate 2 of its WIFI transmission, and may 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 less than 10%, for example, the packet error rate 1 and/or the packet error rate 2 are greater than 10%, the AP device does not adopt a BT RSSI value-based power down mode for the terminal device, that is, does not use the BT RSSI value to reduce the WIFI transmit power.

At this time, the AP device may not reduce WIFI transmit power (using normal mode). The terminal device does not adopt a BT RSSI value-based power-down mode for the AP device, but may use a predefined mode to reduce the WIFI transmit power (for example, reduce the WIFI transmit power by the WIFI RSSI value) or not reduce the WIFI transmit power.

Step 39: if the packet error rate 1 and the packet error rate 2 are less than 10%, the AP equipment starts a corresponding power-down mode, namely, a BT RSSI value is used for reducing WIFI transmitting power by adopting a BT RSSI value-based power-down mode aiming at the terminal equipment.

Optionally, in the process of step 39, the AP device may transmit indication information to the terminal device by WIFI to indicate that the power-down mode based on the BT RSSI value may be adopted. And after the terminal device receives the indication information, one of the following operations may be performed:

if the terminal equipment supports a power-down mode based on the BT RSSI value, the BT RSSI value is used for reducing the WIFI transmitting power aiming at the AP equipment;

if the terminal device does not support the power-down mode based on the BT RSSI value, a predefined mode is used to decrease the WIFI transmit power (e.g., decrease the WIFI transmit power by the WIFI RSSI value) or not decrease the WIFI transmit power.

It should be noted that, whether or not the BT RSSI value-based power down mode may be adopted, the AP device may continuously monitor the BT RSSI value and confirm whether or not the power down power standard is satisfied, so as to determine whether or not to continuously decrease the WIFI transmission power. The BT RSSI value-based power down mode defined herein may be applied to high data rate (high data rate) situations of various WIFI protocols such as 2.4G 11b/G/N or 5G A/N/AC.

The power adjustment in the specific example will be described below with reference to scenario one to scenario three.

Scene one

As shown in fig. 4, the handheld device is used as a WIFI AP, the power is adjustable, and the operating frequency is 2.4G. At this time, if both the WIFI AP and the terminal device 1 (which may be abbreviated as user 1) have BT functions, after the terminal device 1 is connected 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 the power can be reduced by receiving the 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 both the WIFI AP and the WIFI PER (Packet Error Rate ) of the terminal device 1 meet the conditions, a WIFI power adjustment mechanism is started, if the WIFI AP uses the BT RSSI value for the terminal device 1 to reduce the WIFI transmit power, and meanwhile, the terminal device 1 uses the BT RSSI value for the WIFI AP to reduce the WIFI transmit power; for example, from both sides of the original 15dBm, the voltage is reduced to 0dBm.

Meanwhile, the WIFI AP is connected with another device (such as terminal device 2, which may be abbreviated as user 2) by WIFI, and initiates BT connection. 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 mode based on the BT RSSI value is not adopted. For example, the WIFI AP maintains the WIFI power of the terminal device 2 at 15dBm, and the terminal device 2 may use a predefined manner to reduce the WIFI transmit power or not reduce the WIFI transmit power (e.g. the WIFI transmit power is maintained at 15 dBm).

Therefore, when the handheld device is used as the WIFI AP, the WIFI transmitting power can be adjusted according to different users (namely different terminal equipment) and different distances between the handheld device and 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, the power is adjustable, and the operating frequency is 2.4G. At this time, if both the WIFI AP and the terminal device 3 (which may be abbreviated as user 3) have BT functions, after the terminal device 3 is connected to the WIFI AP, the BT connection may be started simultaneously by using software. However, if the terminal device 3 does not have the function of reducing the WIFI power, if 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 conditions, only the WIFI AP may reduce the WIFI transmit power by using the BT RSSI value for the terminal device 3, for example, from 15dBm to 0dBm. While the terminal device 3 maintains the WIFI transmit power (e.g. 15 dBm) unchanged.

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

Scene three

As shown in fig. 6, the handheld device is used as a WIFI AP, the power is adjustable, and the operating frequency is 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 (may be abbreviated as user 5), or the BT connection cannot be performed 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 use the BT RSSI value-based power-down mode for the terminal device 5, and for example, maintains the WIFI transmit power (e.g., 15 dBm) unchanged. The terminal device 5 may use a predefined manner to reduce the WIFI transmit power (e.g. from 15dBm to 0 dBm) or not, so as to maintain good downward compatibility.

From the above, it can be seen that: when the BT RSSI value is utilized to judge whether the WIFI transmitting power of the WIFI AP and the WIFI transmitting power of the terminal equipment can be reduced, the terminal equipment can also achieve the power saving mode at the same time except for the WIFI AP which can reduce the WIFI transmitting power under the condition of maintaining stable high transmission rate, and the mode of reducing the power 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 are transmitting data, transmission is mainly performed based on a WIFI connection or a BT connection. If the WIFI (for example, 11ac MCS9, with a bandwidth of 80 MHz) is the main transmission path, the BT RSSI value is used as a basis to adjust the WIFI transmitting power at this time, so that the power of the mutual transmission can be reduced, and the power saving effect is achieved when the transmission rate is maintained at the highest state.

The touch detection device detects the touch azimuth of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends the touch point coordinates to the processor 810, and receives and executes commands sent from the processor 810. In addition, the touch panel 8071 may be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 8071, the user input unit 807 can include other input devices 8072. In particular, other input devices 8072 may include, but are not limited to, physical keyboards, function keys (e.g., volume control keys, switch keys, etc.), trackballs, mice, joysticks, and so forth, which are not described in detail herein.

Further, the touch panel 8071 may be overlaid on the display panel 8061, and when the touch panel 8071 detects a touch operation thereon or thereabout, the touch operation is transmitted to the processor 810 to determine a type of touch event, and then the processor 810 provides a corresponding visual output on the display panel 8061 according to the type of touch event. Although in fig. 8, the touch panel 8071 and the display panel 8061 are two independent components to implement the input and output functions of the terminal, in some embodiments, the touch panel 8071 and the display panel 8061 may be integrated to implement the input and output functions of the terminal, which is not limited herein.

The interface unit 808 is an interface to which an external device is connected to the terminal 800. For example, the external devices may include a wired or wireless headset port, an external power (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device having an identification module, an audio input/output (I/O) port, a video I/O port, an earphone port, and the like. The interface unit 808 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the terminal 800 or may be used to transmit data between the terminal 800 and an external device.

The memory 809 can be used to store software programs as well as various data. The memory 809 may mainly include a storage program area that may store an operating system, application programs required for at least one function (such as a sound playing function, an image playing function, etc.), and a storage data area; the storage data area may store data (such as audio data, phonebook, etc.) created according to the use of the handset, etc. In addition, the memory 809 may include high speed random access memory, and may 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 running or executing software programs and/or modules stored in the memory 809 and calling data stored in the memory 809, thereby performing overall monitoring of the terminal. The processor 810 may include one or more processing units; preferably, the processor 810 may integrate an application processor that primarily handles operating systems, user interfaces, applications, etc., with a modem processor that primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 810.

Terminal 800 may also include a power supply 811 (e.g., a battery) for powering the various components, and preferably, power supply 811 may be logically coupled to processor 810 through a power management system that provides for managing charge, discharge, and power consumption.

In addition, the terminal 800 may further include some functional modules, which are not shown, and will not be described herein.
