Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

In order to solve the problem of poor communication performance of the terminal using the wireless network due to the reduction of the power consumption of the AP, an embodiment of the present invention provides a method for adjusting the power consumption of the AP, as shown in FIG. 1 , the method includes:

101. The home gateway periodically receives the WIFI negotiation rate and the actual connection rate sent by the terminal, and the WIFI negotiation rate is used to limit the actual connection rate.

Wherein, the terminal is a terminal that accesses the home gateway through the AP. The terminal can determine the WIFI negotiation rate according to the wireless protocol standard of the currently used wireless network and the received wireless signal strength. For example, the wireless protocol standard 802.11g stipulates that the WIFI negotiation rate can be 0Mbit/s, 12Mbit/s, 18Mbit/s, 24Mbit/s, 36Mbit/s, 48Mbit/s or 54Mbit/s, each value of WIFI negotiation rate corresponds to a range of wireless signal strength.

The actual connection rate of the terminal is limited by the WIFI negotiation rate. The WIFI negotiation rate is the theoretical maximum of the actual connection rate, but generally the actual connection rate will not reach the WIFI negotiation rate. The speed measurement software in the terminal can measure the actual connection rate, thereby making The terminal can send the actual connection rate to the home gateway.

102. The home gateway adjusts the power consumption of the AP according to the relationship between the WIFI negotiation rate and the actual connection rate.

It is worth noting that since the actual connection rate of the terminal is limited by the WIFI negotiation rate, it is necessary to adjust the power consumption of the AP according to the magnitude relationship between the WIFI negotiation rate and the actual connection rate corresponding to the same terminal. It will increase with the increase of the power consumption of the AP, and decrease with the decrease of the power consumption of the AP. After the wireless signal strength increases within a certain range, the WIFI negotiation rate will also become a larger value. For example, The current WIFI negotiation rate is 18Mbit/s. At this time, the power consumption of the AP increases, and the wireless signal strength also increases. After the wireless signal strength increases beyond the range corresponding to 18Mbit/s, the WIFI negotiation rate will increase. Change to 24Mbit/s. Similarly, after the wireless signal strength decreases within a certain range, the WIFI negotiation rate will become a smaller value.

In the AP power consumption adjustment method provided by the embodiment of the present invention, the home gateway periodically receives the WIFI negotiation rate and the actual connection rate of the terminal, and then adjusts the power consumption of the AP according to the relationship between the WIFI negotiation rate and the actual connection rate. Compared with reducing the power consumption of the AP in order to reduce the radiation in the prior art, resulting in poor communication performance of the terminal using the wireless network, the embodiment of the present invention can adjust the AP through the size relationship between the WIFI negotiation rate and the actual connection rate Since the actual connection rate can reflect the terminal's demand for speed, and the actual connection rate is limited by the WIFI negotiation rate, so adjusting the power consumption of the AP according to the terminal's demand for speed can control radiation while ensuring that the terminal The actual connection rate, thereby ensuring the communication performance of the terminal using the wireless network.

In combination with the method flow shown in FIG. 1, in order to ensure the communication performance of the terminal using the wireless network while controlling the radiation, in another implementation mode provided by the embodiment of the present invention, as shown in FIG. 2, the above step 102, the home gateway According to the size relationship between the WIFI negotiation rate and the actual connection rate, the power consumption of the AP is adjusted, which can be specifically implemented as the following steps 1021 to 1022 .

1021. When the home gateway determines that the actual connection rate is lower than the first threshold of the WIFI negotiation rate, reduce the power consumption of the AP.

Among them, the first threshold of the WIFI negotiation rate is generally 30% of the WIFI negotiation rate. When the actual connection rate of the terminal is lower than 30% of the WIFI negotiation rate, it means that the current demand of the terminal for the rate is relatively low, and the current WIFI negotiation rate If the value is too high, the current wireless signal strength is relatively high, which will generate greater radiation, so reducing the power consumption of the AP at this time will not affect the actual connection rate of the terminal, and can also reduce the radiation.

It is worth noting that reducing the power consumption of the AP will weaken the strength of the wireless signal, thereby reducing the WIFI negotiation rate and radiation.

1022. When the home gateway determines that the actual connection rate is higher than the second threshold of the WIFI negotiation rate, increase the power consumption of the AP, and the first threshold is smaller than the second threshold.

Among them, the second threshold of the WIFI negotiation rate is generally 70% of the WIFI negotiation rate. When the actual connection rate of the terminal is higher than 70% of the WIFI negotiation rate, it means that the terminal currently has a relatively high demand for rate, and the current WIFI negotiation rate If it is too low, there is no room for improvement in the actual connection rate of the terminal. The current actual connection rate can no longer meet the terminal's demand for speed. Therefore, in order to ensure the communication performance of the mobile terminal, it is necessary to increase the power consumption of the wireless AP appropriately so that the wireless signal As the intensity increases, the WIFI negotiation rate increases. After the WIFI negotiation rate increases, the actual connection rate of the terminal also has room to increase.

It is worth noting that the WIFI negotiation rate is the theoretical maximum of the actual connection rate, but in fact, the actual connection rate can only be about 80% of the WIFI negotiation rate, so when the actual connection rate has reached 70% of the WIFI negotiation rate , it is very likely that the terminal needs a larger actual connection rate at this time, but it cannot continue to increase due to the limitation of the WIFI negotiation rate. At this time, in order to ensure the communication performance of the terminal, it is necessary to increase the power consumption of the AP. WIFI negotiation rate.

For example, the current WIFI negotiation rate of a notebook computer is 54Mbit/s. At this time, the user may only use the notebook computer to browse the web, so the actual connection rate is only 3Mbit/s, which is far lower than the WIFI negotiation rate. At this time, the notebook computer has the ability to increase The actual connection rate is large, but it has not increased, which means that the current notebook computer has a low demand for speed. In order to reduce radiation, the power consumption of the AP can be reduced, thereby reducing the WIFI negotiation rate.

Or the WIFI negotiation rate of a mobile phone is 36Mbit/s. At this time, the user may be using the mobile phone to watch high-definition video. The actual connection rate of the mobile phone has reached 27Mbit/s. Under the limitation of the WIFI negotiation rate at this time, the actual connection rate The maximum can only reach about 28Mbit/s. At this time, the mobile phone may need a larger actual connection rate, but limited by the WIFI negotiation rate, there is no ability to increase the actual connection rate. Therefore, in order to ensure the communication performance of the mobile phone using the wireless network, it is necessary to Increase the power consumption of the AP, thereby increasing the WIFI negotiation rate.

In addition, it should be noted that multiple terminals can access the home gateway through the same AP. When the home gateway determines that the actual connection rate of one terminal is lower than the first threshold of the WIFI negotiation rate, while the actual connection rate of the other terminal is higher than When the second threshold of the WIFI negotiation rate is reached, the home gateway increases the power consumption of the AP to ensure that there is room for improvement in the actual connection rate of terminals with higher rate requirements, thereby ensuring the communication performance of terminals with higher rate requirements.

In the AP power consumption adjustment method provided by the embodiment of the present invention, the home gateway periodically receives the WIFI negotiation rate and the actual connection rate of the terminal, and when the home gateway determines that the actual connection rate is lower than the first threshold of the WIFI negotiation rate, the power of the AP is reduced. When the home gateway determines that the actual connection rate is higher than the second threshold of the WIFI negotiation rate, the power consumption of the AP is increased. Compared with reducing the power consumption of the AP in order to reduce radiation in the prior art, resulting in poor communication performance of the terminal using the wireless network, in the embodiment of the present invention, when the home gateway determines that the actual connection rate is lower than the first WIFI negotiation rate When a threshold is set, it means that the current demand of the terminal for the actual connection rate is small, so the power consumption of the AP is reduced to make the radiation lower. When the home gateway determines that the actual connection rate is higher than the second threshold of the WIFI negotiation rate, it means that the terminal's current The WIFI negotiation rate can no longer meet the terminal's demand for the actual connection rate, so the power consumption of the AP is increased to ensure the communication performance of the terminal using the wireless network. In summary, the method for adjusting the power consumption of the AP provided by the embodiment of the present invention can On the premise of ensuring the communication performance of the terminal using the wireless network, the radiation should be reduced as much as possible.

In combination with the above description, in order to ensure the communication performance of the terminal using the wireless network while controlling the radiation, in another implementation mode provided by the embodiment of the present invention, as shown in FIG. 3 , the above step 101, the home gateway periodically receives the terminal's The WIFI negotiation rate and the actual connection rate can be specifically implemented as the following step 1011, which is used to limit the period of the WIFI negotiation rate and the actual connection rate of the home gateway receiving terminal.

1011. The home gateway receives the WIFI negotiation rate and the actual connection rate of the terminal every 300 seconds.

It is worth noting that the home gateway can receive the WIFI negotiation rate and the actual connection rate of the terminal every 300 seconds. When a new terminal accesses the home gateway through the AP, it needs to report the current WIFI negotiation rate and actual connection rate to the home gateway. After that, the home gateway can also receive the WIFI negotiation rate and actual connection rate of the new terminal every 300 seconds rate.

Among them, if the period for the terminal to report the WIFI negotiation rate and actual connection rate to the home gateway is too short, resources will be wasted, and if the period is too long, the home gateway will not be able to obtain the latest WIFI negotiation rate and actual connection rate of the terminal in time, resulting in the adjustment of the AP's The power consumption is not accurate, so generally the reporting period of the terminal is set to 300 seconds, which can ensure the accuracy of adjusting the power consumption of the AP without wasting too many resources.

In the AP power consumption adjustment method provided by the embodiment of the present invention, the home gateway receives the WIFI negotiation rate and the actual connection rate of the terminal every 300 seconds, and then when the home gateway determines that the actual connection rate is lower than the first threshold of the WIFI negotiation rate, Reduce the power consumption of the AP, and increase the power consumption of the AP when the home gateway determines that the actual connection rate is higher than the second threshold of the WIFI negotiation rate. Compared with reducing the power consumption of the AP in order to reduce radiation in the prior art, resulting in poor communication performance of the terminal using the wireless network, in the embodiment of the present invention, the home gateway can judge the actual connection rate of the terminal every 300 seconds The relationship with the WIFI negotiation rate. When the home gateway determines that the actual connection rate is lower than the first threshold of the WIFI negotiation rate, it means that the current demand for the actual connection rate of the terminal is small, so the power consumption of the AP is reduced to make the radiation lower. When When the home gateway determines that the actual connection rate is higher than the second threshold of the WIFI negotiation rate, it means that the terminal's current WIFI negotiation rate can no longer meet the terminal's demand for the actual connection rate, so the power consumption of the AP is increased to ensure that the terminal uses the wireless network. Communication performance. In summary, the AP power consumption adjustment method provided by the embodiment of the present invention can reduce radiation as much as possible on the premise of ensuring the communication performance of the terminal using the wireless network.

The receiving unit 401 is configured to periodically receive the WIFI negotiation rate and the actual connection rate sent by the terminal, and the WIFI negotiation rate is used to limit the actual connection rate;

The adjustment unit 402 is configured to adjust the power consumption of the AP according to the magnitude relationship between the WIFI negotiation rate and the actual connection rate.

In another embodiment of the present invention, the adjustment unit 402 is further configured to reduce the power consumption of the AP when it is determined that the actual connection rate is lower than the first threshold of the WIFI negotiation rate; When the second threshold is reached, the power consumption of the AP is increased, and the first threshold is smaller than the second threshold.

Wherein, the first threshold of the WIFI negotiation rate is 30% of the WIFI negotiation rate; the second threshold of the WIFI negotiation rate is 70% of the WIFI negotiation rate.

In another embodiment of the present invention, the receiving unit 401 is further configured to receive the WIFI negotiation rate and the actual connection rate sent by the terminal every 300 seconds.

In the AP power consumption adjustment device provided by the embodiment of the present invention, the receiving unit periodically receives the WIFI negotiation rate and the actual connection rate of the terminal, and then the adjustment unit adjusts the power consumption of the AP according to the relationship between the WIFI negotiation rate and the actual connection rate. Compared with reducing the power consumption of the AP in order to reduce the radiation in the prior art, resulting in poor communication performance of the terminal using the wireless network, the embodiment of the present invention can adjust the AP through the size relationship between the WIFI negotiation rate and the actual connection rate Since the actual connection rate can reflect the terminal's demand for speed, and the actual connection rate is limited by the WIFI negotiation rate, so adjusting the power consumption of the AP according to the terminal's demand for speed can control radiation while ensuring that the terminal The actual connection rate, thereby ensuring the communication performance of the terminal using the wireless network.
