Description
Technical Field

Background
With the development of wireless network technology, wireless routers are increasingly used. Many routers now have two rf bands, 2.4G and 5G, and when connecting WI-FI (WIreless-FIdelity) via a dual-band router, a user can conveniently select between the two bands 2.4G and 5G, but usually selects one of them manually for connection.
On day 16, 9.2019, the Wi-Fi alliance announced the initiation of a Wi-Fi 6 certification program aimed at meeting established standards for devices employing the next generation of 802.11ax Wi-Fi wireless communication technologies. Wi-Fi 6 mainly uses OFDMA, MU-MIMO (Multi-user multiple input multiple output), etc., which allows routers to communicate with multiple devices at the same time, rather than sequentially. MU-MIMO allows a router to communicate with four devices at a time, Wi-Fi 6 will allow communication with up to 8 devices. Wi-Fi 6 also utilizes other techniques, such as OFDMA (orthogonal frequency division multiple access) and transmit beamforming, the roles of which respectively improve efficiency and network capacity. The Wi-Fi 6 highest speed can reach 9.6 Gbps.

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 application.
Fig. 1 is a schematic structural diagram of a router provided in an embodiment of the present application, and is shown in fig. 1, where: wifi6 communication chip 100, power distribution module 200, 5G transceiver module 300, and 2.4G transceiver module 304, wherein 5G transceiver module 300 and 2.4G transceiver module 400 are both directly connected to corresponding pins of wifi6 communication chip 100, and 5G transceiver module 300 further includes: 5G transmitting antenna 301 and 5G receiving antenna 302, 2.4G transceiver module 400 further includes: a 2.4G transmit antenna 401 and a 2.4G receive antenna 502.
The 5G transceiver module 300 is provided with a first power acquisition module 201, and an input end of the first power acquisition module 201 is connected with the 5G transceiver module 300 and is used for acquiring real-time power of the 5G transceiver module 300 or acquiring according to a set acquisition time; similarly, the 2.4G transceiver module 400 is provided with a second power acquisition module 202, and an input end of the second power acquisition module 202 is connected to the 2.4G transceiver module 400, and is configured to acquire the real-time power of the 2.4G transceiver module 400, or acquire the real-time power according to a set acquisition time.
In addition, the output end of the first power collecting module 20, 1 and the output end of the second power collecting module 202 are respectively connected to the input end of the power distributing module 200, and the output end of the power distributing module 200 is connected to the power control end of the wifi6 communication chip, and is used for controlling the power of the 5G transceiver module 300 and the 2.4G transceiver module 400 during operation.
In the embodiment shown in fig. 1 of the present application, only two frequency band communication modules, namely, the 5G transceiver module 300 and the 2.4G transceiver module 400, are taken as an example for description, in other embodiments, the wifi6 chip may further be provided with more frequency band communication modules, and details are not described herein.
Fig. 2 is a wifi6 device control method provided in an embodiment of the present application, where fig. 2 is applied to the router device shown in fig. 1, and as shown in fig. 2, the method may include:
s101, a plurality of detection power values of each frequency band communication module at different acquisition moments are obtained.
Referring to fig. 1, the input end of the first power collecting module 201 is connected to the 5G transceiver module 300, and is configured to collect real-time power of the 5G transceiver module 300, so that in this step, the detection power value output by the first power collecting module 201 may be received. Similarly, the detected power value output by the second power collecting module 202 may be received.
S102, determining a power change curve of the power of each frequency band communication module according to the plurality of detection power values of each frequency band communication module.
After a plurality of detection power values are obtained through detection, a power change curve of the power of each frequency band communication module along with different acquisition moments can be drawn in a coordinate system according to the relation between the detection power values and the detection moments.
S103, determining the power change rate of each frequency band communication module according to the power change curve of each frequency band communication module.
In the embodiment of the present application, the power value is related to the number of terminals carried by the frequency band, and the data transmission frequency and the transmission amount. Taking the 5G frequency band as an example, when the number of terminals carried in the 5G frequency band increases, the power of the corresponding 5G frequency band will obviously increase, and in addition, when the transmission amount of the terminals carried in the 5G frequency band increases, for example; when watching high definition video, the power of the corresponding 5G band will obviously increase, and when the transmission frequency of the terminal carried by the 5G band increases, for example: high frequency data interaction is required and the power of the corresponding 5g band is obviously increased by an increasing amount.
However, the power at a certain collection time cannot reflect the overall variation trend, for example: when the mobile phone is newly accessed to the router, high-frequency data interaction occurs, but stable data interaction can be achieved after connection, and sudden change cannot occur. For this purpose, the step may adopt a manner that a slope value of two adjacent power value points in the power change curve is taken as a slope value point, and then a slope of the slope value point is calculated again as the power change rate.
And S104, predicting the power predicted value of the corresponding next acquisition moment according to the power change rate of each frequency band communication module.
For a terminal device of a stable access router, the usage of a user is regular in view of historical data, for example: after the user goes off duty every day, the user listens to songs through a mobile phone earphone when cooking, watches a television when eating, possibly browses short videos after eating, rarely interacts with the router after having a rest at night, browses the mobile phone after the user gets up, and then watches the television.
However, the historical situation does not represent the situation that happens today, so in the scheme, according to the previous use situation, the power change rule of each classmate frequency module of the current router is found, and then the power value is predicted according to the power change rule. In this embodiment of the present application, the next acquisition time may be the next adjacent acquisition time, or may be other times defined by the user.
And S105, dynamically distributing the working power of each frequency band communication module according to the power predicted value of each frequency band communication module at the next acquisition moment.
The power prediction value of each frequency band communication module at the next acquisition time, that is, the power condition at the next acquisition time, is obtained, and a basis can be provided for power distribution. In this step, the total power of the router is combined, so that the free allocation can be performed among the frequency band communication modules.
Compared with the existing router, the method provided by the embodiment of the application can be used for solidifying the working power of each frequency band communication module in the router, and the working power of each frequency band communication module can be adjusted. The specific mode is that the power of the next collection time can be predicted by using frequency detection values of a plurality of historical collection times to obtain a power prediction value. And temporarily allocating the working power of each frequency band communication module in the router according to the predicted power value. Therefore, the method can enable the power of each frequency band communication module to be matched with the actually required power as much as possible, and further enable the communication quality of each frequency band communication module to be free from the problem caused by the factor of fixed power.
In an embodiment of the present application, as shown in fig. 3, the foregoing step S101 may include the following steps:
and S10111, acquiring a preset acquisition interval.
The preset collection interval can be set when the router leaves a factory, and in addition, the preset collection interval can also be used as an attribute parameter of the router, and a user can modify the router in a management background of the router by himself. In the embodiment of the present application, in consideration of the timeliness of router communication, the preset collection interval may be on the order of hours, for example: 0.2 hour, 0.5 hour, etc. In other embodiments, for scenarios where data interaction is more frequent, for example: race, etc., the acquisition intervals may also be set in stages, such as: 3 minutes, 5 minutes, or 10 minutes.
S10112, collecting a plurality of detection power values of each frequency band communication module at different collection moments according to the preset collection interval.
And after the acquisition interval is acquired, timing according to a self-contained timer in the router, starting timing after the previous acquisition is finished, and performing the next acquisition when the timing time is equal to the preset acquisition interval.
In another embodiment of the present application, as shown in fig. 4, the foregoing step S101 may include the following steps:
s10121, controlling a power acquisition module arranged on each frequency band communication module to obtain at least two historical power detection values according to a preset acquisition interval;
in the embodiment of the present application, two adjacent historical detection power values refer to two historical detection power values closest to the current acquisition time.
S10122, calculating a next acquisition interval based on the at least two historical detection power values;
in consideration of the fact that in actual detection, if power data are relatively stable and do not change, the embodiment shown in fig. 3 can be directly adopted, but if a historical power detection value acquired recently indicates that power is relatively unstable, power change needs obviously not to be met according to an original acquisition interval, and therefore the acquisition interval needs to be shortened.
And S10123, controlling a power acquisition module arranged on each frequency band communication module to perform next power detection according to a next acquisition interval to obtain a next power detection value.
In the embodiment of the present application, step S0122 in fig. 4 may adopt the following manner:
and the Sp11 judges whether the historical detection power value of the current acquisition time is larger than the historical detection power value of the previous acquisition time according to the sequence of the acquisition times.
The impact on the communication quality only occurs when the power is increased, so when the acquisition interval is adjusted, the trigger condition is that the historical detection power value tends to increase.
Sp12, if the current historical detected power value is larger than the previous historical detected power value, determining the first interval reduction amount according to the preset interval reduction rule.
In an embodiment of the present application, the first interval reduction may be 10% of the acquisition interval.
Sp13, subtracting the first interval reduction amount from the preset acquisition interval to obtain the next acquisition interval.
In the embodiment of the present application, when the detection power value tends to increase, the acquisition interval may be reduced at a speed of 10% each time, but considering that the acquisition frequency is too high, the power consumption may be increased, so in the embodiment of the present application, the next acquisition interval may not be less than 30% of the preset acquisition interval.
In the embodiment of the present application, step S0122 in fig. 4 may adopt the following manner:
and Sp21, judging whether the increment of the power change rate at the current acquisition time is larger than that at the previous acquisition time according to the sequence of the acquisition times.
In the embodiment of the present application, the individual detected power value is increased, which may be caused by a sudden situation, and the overall power change situation cannot be reflected well. Once the increase amount shows an increasing trend, it indicates that the current power demand is rapidly increasing.
Sp21, if the increase of the power change rate at the previous acquisition time is larger than the increase of the power change rate at the previous acquisition time, determining a second interval reduction amount according to a preset interval reduction rule.
Sp23, subtracting said second interval decrement from said preset acquisition interval to obtain said next acquisition interval.
The second interval reduction amount is different from or the same as the first interval reduction amount, and the description of the first interval reduction amount may be specifically referred to.
In an embodiment within the present application, the aforementioned S103 may include the following steps:
and S1031, marking the power detection value point corresponding to each acquisition time in a first coordinate system of the time and power detection values.
Referring to fig. 5, the diagram includes t1-t12, and the total number of the power detection value points is 12, and the corresponding power detection value points are p1-p12, where the abscissa of each power detection value point p is the acquisition time and the ordinate is the power value w.
And S1032, performing curve smooth connection on all the power detection value points according to a curve connection mode, and drawing a power change curve of each frequency band communication module.
Referring to fig. 5, the power variation curve of each power detection value can be obtained by smoothly connecting all the power detection value points in a curve manner. Fig. 5 is a power variation curve corresponding to a certain frequency band communication module.
In one embodiment, the foregoing step S104 may include the following steps:
s1041, calculating a first slope value of a connecting line between power detection value points at two adjacent acquisition moments in a power change curve;
referring to fig. 5, the first slope value of the straight line where p3 and p4 are located is k 4; the first slope value of the straight line on which p4 and p5 are located is k 5; the first slope value of the straight line on which p5 and p6 are located is k 6; the first slope value of the straight line on which p6 and p7 lie is k 7.
S1042, marking a slope value point corresponding to the slope value of each acquisition time and the previous acquisition time in a second coordinate system of time and the first slope value;
referring to fig. 6, in the second coordinate system, a slope value point k is marked, the abscissa of the slope value point is the acquisition time, and the ordinate is the slope value. It can be seen from fig. 6 that the slope values have positive values and also negative values.
S1043, performing curve smooth connection on all slope value points according to a curve connection mode to obtain a slope value change curve of each frequency band communication module;
and connecting the slope value points according to a curve smooth transition mode to obtain a power value change curve shown in fig. 6.
And S1044, calculating a second slope of a connecting line between slope value points of two adjacent acquisition moments in a slope value change curve of each frequency band communication module as a power change rate.
As can be seen from the graph, the second slope value of the straight line in which the slope value points k4 and k5 are located is g 5; the second slope value of the straight line where k5 and k6 are located is g 6; the second slope value of the straight line containing p6 and p7 is k 7.
From the change of the second slope value, the power value is at an increase when the second slope value is positive, and the power increase is larger the positive value of the second slope value is. Therefore, the speed of detecting the change of the power value can be seen to be the highest speed or the slower speed through the second slope value, and a basis is provided for power prediction.
In an embodiment of the present application, the foregoing step S104 may include the following steps:
and S1041, according to the trend of the slope value change curve of each frequency band communication module, prolonging the slope value change curve of each frequency band communication module, and marking a predicted slope value corresponding to the next acquisition time after the latest acquisition time on the prolonged slope value change curve.
Referring to fig. 6, in the graph, according to the slope value point k12, the previous slope value change curve may be extended, and after the extension, the predicted slope value corresponding to the next acquisition time t13 may be reached.
And S1042, calculating a power predicted value of each frequency band communication module in the power change curve of each frequency band communication module according to the predicted slope value.
In fig. 5, according to the preset slope value, a power value point P13 can be calculated, and then a power predicted value is obtained through the ordinate of P13.
In an embodiment of the present application, the foregoing step S106 may include the following steps:
s1051, according to the predicted value of the power of each frequency band communication module, determining the power distribution proportion of the communication modules in different frequency bands.
The power distribution proportion is equal to the proportion of the predicted power value of each frequency band communication module, for example: the predicted power value of the 2.4G communication module is 2.4 w, and the predicted power value of the 5G communication module is 4.8 w, so that the power distribution ratio of the 2.4G communication module and the 5G communication module is 2.4/4.8 which is 1: 2.
And S1052, sending the power distribution proportion to a power distribution module of the router, so that the power distribution module adjusts the working power of the communication modules in different frequency bands according to the power distribution proportion.
For the router, if the total power of the router is 10 watts, the initial power of the 2.4G communication module is 2 watts, and the initial power of the 5G communication module is 8 watts, then the regulated power of the 2.4G communication module is 3.3 watts and the regulated power of the 5G communication module is 6.7 watts according to the ratio of 1: 2. And then can satisfy two communication module's respective requirements for communication signal is stable.
However, in practical applications, according to the power distribution ratio, the distributed power cannot meet the requirements of all power modules, for example: when the total power is 10 watts, the predicted power values of the 2.4G communication module and the 5G communication module are both 5.5w, that is, the power is distributed according to the ratio of 1:1, so that the power of the 2.4G communication module is 5 watts, and the distributed power of the 5G communication module is 5 watts, which makes both communication modules unable to meet the requirements.
For this reason, in other embodiments of the present application, step S105 of the method may further include the following steps:
s1053, according to the total power of the router and the power distribution proportion, calculating the quasi-distribution power value of each frequency band communication module;
s1053, comparing the power value to be distributed of each frequency band communication module with the respective corresponding power predicted value;
and if the power values to be allocated of each frequency band communication module meet the respective corresponding power predicted values, executing the step of direct allocation of S1052.
If the power value to be allocated of any frequency band communication module does not meet the corresponding power predicted value, other judgment conditions can be added.
In an embodiment of a specific location, if a power value to be allocated of any frequency band communication module does not satisfy a power predicted value corresponding to each power value, step S105 of the method may further include:
and S1054, judging whether the communication priority of the frequency band communication module of which the power value to be allocated does not meet the corresponding power predicted value is larger than a preset value.
The communication priority is the priority of communication modules in different frequency bands preset in the router by the user, for example: in a router having 2.4G and 5G communication modules, the priority of the 5G communication module may be set higher than that of 2.4G, and for the sake of easy fine management, the priority of the 2.4G communication module may be set to 3, and the priority of the 5G communication module may be set to 8.
If the communication priority of the frequency band communication module for which the power value to be allocated does not satisfy the corresponding power prediction value is not greater than the preset priority value, the step of directly allocating is executed in S1052.
In the embodiment of the application, for the frequency band communication module with a lower priority, direct distribution can be performed without considering whether the power value to be distributed meets the corresponding power predicted value or not due to the lower priority.
In another embodiment, if the power values to be allocated of two or more frequency band communication modules do not satisfy the respective corresponding power prediction values, S105 in the method may further include the following steps:
and acquiring the communication priorities of all the frequency band communication modules, distributing the frequency band communication modules with the communication priorities smaller than or lower than the preset priority value according to the corresponding reserved power values, and distributing the residual power in the frequency band communication modules with the communication priorities larger than the preset priority value.
Scene one:
taking the router total power as 10 watts, the initial power of the 2.4G communication module as 2 watts, and the initial power of the 5G communication module as 8 watts as an example, if the power prediction value of the 2.4G communication module is 4 watts and the power prediction value of the 5G communication module is 8 watts, then the power distribution ratio of the 2.4G communication module and the 5G communication module is 4/8-1: 2.
Then, in a 2:3 ratio, the regulated power of the 2.4G communication module should be 3.33 watts and the regulated power of the 5G communication module should be 6.67 watts.
But in the priority case: the priority of the 2.4G communication module can be set to be 3, the priority of the 5G communication module can be set to be 8, and the pre-priority value is 5. By applying the method, it can be seen that, for the 2.4G communication module, the initial power value can be continuously reserved for 2 watts (namely, the reserved power value) due to the lower priority, while for the 5G communication module, the residual power except for 2 watts can be satisfied for the 5G communication module due to the higher priority, and since the predicted power value of the 5G communication module is 8 watts, the residual power can be completely allocated to the 5G communication module, namely, 8 watts except for the reserved 2 watts, so that the condition of higher priority can be satisfied as much as possible.
Scene two:
taking the total power of the router as 10 watts, the initial power of the 2.4G communication module as 2 watts, the initial power of the 5G communication module as 6 watts, and the standby power as 2 watts as an example, if the power prediction value of the 2.4G communication module is 2 watts and the power prediction value of the 5G communication module is 8 watts, then the power distribution ratio of the 2.4G communication module and the 5G communication module is 2/8 as 1: 4.
Then the regulated power of the 2.4G communication module is 2 watts and the regulated power of the 5G communication module is 8 watts, in a 1:4 ratio. But in the priority case: the priority of the 2.4G communication module can be set to be 3, the priority of the 5G communication module can be set to be 8, and the pre-priority value is 5. By applying the method, it can be seen that, for the 2.4G communication module, the initial power value can be continuously reserved for 2 watts (power value is also reserved) due to the lower priority, while for the 5G communication module, the residual power except for 2 watts can be satisfied with the 5G communication module due to the higher priority, and since the predicted power value of the 5G communication module is 8 watts, the residual power can be completely allocated to the 5G communication module except for the reserved 2 watts from 10 watts, that is, 8 watts, so that the condition of higher priority can be satisfied as much as possible.
