Background
In the existing wlan technology, in an environment where access point devices (APs) are deployed at a high density, there are more Overlapping Basic Service Sets (OBSSs), which means that more communication collisions occur. When Color (Color) values of two or more Basic Service Sets (BSSs) in the OBSS collide, each station device (STA) informs the AP of the collision by sending a BSS Color value collision report, and then the AP performs a Color value change again. However, the prior art has the following technical drawbacks: 1) the changed BSS Color values have high possibility of being repeated, and when the changed BSS Color values conflict, a conflict report needs to be sent again to enable all the APs with the changed BSS Color values to conflict to change; 2) when the change countdown of the two BSSs approaches, the first device AP1 sends a change completion command to the STA1 after completing the change, and the change completion command is also received by the STA2, and then the STA2 sends a change stop command to the second device AP2 matching the STA2, the AP2 has completed the BSS Color value change, the AP2 still causes a loss of sending a change declaration frame during the change, and the AP2 also generates an unnecessary change loss. Therefore, the efficiency of changing the BSS Color value is reduced, and the communication quality of the wireless network is affected.
In summary, the existing wireless network communication has the problems that the efficiency of changing the BSS Color value is low, and the wireless network communication quality is influenced.

It should be noted that an Access Point (AP) is a wireless access point, is a creator of a wireless network, and is a central node of the network. For example, a wireless router used in a home or office is an AP. Station equipment (STA) refers to each terminal connected to a wireless network, such as a laptop, PDA, and other user equipment that can be networked.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of the method for determining a BSS Color value according to the embodiment of the present application, where STA1, STA2, and STA3 are station devices, AP1, AP2, and AP3 are access points, and are respectively matched with the station devices, for example, STA1 is matched with AP1 correspondingly, STA2 is matched with AP2 correspondingly, and STA3 is matched with AP3 correspondingly. The STA1 is defined as a first station device, the AP1 is defined as a first access point, the STA2 and the STA3 are both second station devices, and the AP2 and the AP3 are both corresponding to second access points. Wherein, BSS1, BSS2, BSS3 correspond to a group of station devices and access points communicating with each other, and when BSS colors of BSS1, BSS2, BSS3 are all the same, STA1 will simultaneously detect the collision between BSS1 and BSS2, and will send a Color collision report to AP 1; STA2 may detect the collision of BSS1, BSS2 and BSS3 at the same time and send a collision report to AP2, STA3 may detect the collision of BSS1 and BSS3 and send a collision report to AP3, at this time, AP1, AP2 and AP3 may make BSS Color change at the same time.
Take the station device as a mobile phone as an example. Fig. 2 shows a flowchart of an implementation of the method for determining a BSS Color value provided in embodiment 1 of the present application, which is applied to a first station device, and is detailed as follows:
s101, receiving and analyzing a change management frame sent by access points with the same BSS Color value; the access point includes a first access point and at least one second access point matched with the first station device, the change management frame includes BSSColor change information, and the BSS Color change information includes a current BSS Color value, a changed BSS Color value, and a change countdown.
In application, the first access point is a wireless Access Point (AP), and may specifically be a wireless router, a mobile phone device with a hot spot function, a server with a WI-FI communication function, or the like, which is not limited herein. In the IEEE802.11AX protocol, in a high-density deployment environment of a wireless access point, multiple Overlapping Basic Service Sets (OBSSs) may exist, and to avoid more communication collisions, provide a better channel selection mechanism and increase spatial multiplexing, the BSS Color value mechanism defined in the 11Ah standard is adopted by IEEE802.11AX, so that a station device can identify a data frame from the OBSS. Whether BSS Color value is consistent with the BSS Color value that website equipment can receive is obtained through analyzing the data frame, if unanimous and quantity is only, website equipment then can judge that the data frame received comes from the access point that matches with oneself, if detect the data frame that has a plurality of same BSS Color values, and after analyzing a plurality of data frames, the BSS Color value after the change of acquireing is also the same, then website equipment sends the conflict report for the access point that corresponds, carry out the change of BBS Color value, thereby realize direct backoff, reduce the influence of channel interference to the signal, promote communication efficiency. Referring to fig. 3, the data frame includes a BSS Color field, a partial BSS Color field, and a BSS Color disabled field, where the BSS Color field is a BSS Color value, and when the BSS Color fields in the multiple data frames are analyzed to have the same value, the data frame sends a collision report to the corresponding access point.
In an application, the first access point is an access point device matched with a current station device, the second access point is an access point device respectively matched with other station devices, the second station device is another station device except the first station device, and the number of the second access points may be one or multiple. It is understood that the number of the second station devices may be one or more, which is not limited to this. For example, when the number of the second access points is one, the number of the second station devices may be one or more, and when the number of the second access points is more than one, the number of the second station devices may also be one or more, but each of the second station devices is respectively matched with one second access point. When station equipment detects that the BSS Color value before the change conflicts and/or the BSS Color value after the change conflicts, the corresponding access point sends out a change management frame, and the change management frame is used for indicating that the corresponding access point is in a state of changing the BSS Color value. For example, if the station device detects that the BSS Color value in the data frame sent by the first access point matched with the station device is the same as the BSS Color value of the data frame sent by another access point, the station device sends a collision report of the BSS Color value to the first access point, so that the first access point sends a change management frame to change the BSS Color value again.
In application, referring to fig. 4, the change management frame includes, but is not limited to, a Beacon frame (Beacon), a Probe Response frame (Probe Response), a Probe Association Response frame (Probe Association Response), and a re-Association Response frame (re Association Response), and is not limited thereto. The above change Countdown is a Color Switch count down field, which is used to indicate the Countdown value and is decreased in time sequence, and when the Countdown value is decreased to 0, it indicates that the BSS Color value that conflicts is changed to the changed BSS Color value, i.e., the New BSS Color information in fig. 4.
And S102, if the number of the second access points is less than 2 and the first access point meets a first preset rule, sending a change stop frame to the first access point, wherein the change stop frame is used for indicating the first access point to stop changing the BSSColor value.
In application, the first preset rule is a rule set by comparing the change countdown corresponding to the first access point with the change countdown corresponding to the second access point according to the change countdown, and if the first preset rule is set, the change countdown corresponding to the first access point is greater than the change countdown corresponding to the second access point. The change stop frame is used for indicating the first access point to stop changing the BSS Color value when the first access point meets a first preset rule, namely stopping countdown change countdown, so that the countdown change is not decreased to 0, the first station is enabled to stop the BSS Color value, the first station still keeps the BSS Color value before change, the BSS Color value does not need to be changed, and loss caused by the change of the BSS Color value by the first access point is reduced.
Specifically, when the number of the second access points is less than 2, that is, there is only one second access point, the change count-down times corresponding to the first access point and the second access point are compared, and if the change count-down time corresponding to the first access point is greater than the change count-down time corresponding to the second access point, the first access point is considered to satisfy the first preset rule, and the station device sends a change stop frame to the first access point.
S103, if the number of the second access points is more than or equal to 2 and the first access point meets a first preset rule, sending a conflict report to the first access point; the collision report is used to instruct the first access point to re-alter the BSSColor value.
In application, when the number of the second access points is greater than or equal to 2, the collision report is immediately sent to the first access point meeting the first preset rule. The first access point may be determined to satisfy the first preset rule, and the change countdown corresponding to the first access point is greater than the change countdown corresponding to the second access point. The conflict report is used for indicating the first access point to resend the change management frame, so that the first access point can resend the change management frame immediately, the first access point can renew the BSS Color value, the BSS Color value does not need to wait until the countdown counting down of the first change is completed, and after the BSS Color value is changed, the changed BSS Color value is found to conflict again, and the change efficiency of the BSS Color value is effectively improved.
In the implementation, by receiving and analyzing the change management frames sent by the first access point and the second access point with the same BSS Color value, when the number of the second access points is less than 2 and the first access point meets a first preset rule, a change stop frame is sent to the first access point, so as to avoid the situation that all the APs need to be changed when a plurality of BSS Color values conflict; and if the number of the second access points is more than or equal to 2 and the first access point meets a first preset rule, sending a conflict report to the first access point, so that only one AP is needed to change when the change countdown of the two BSSs is close to each other, and the change efficiency and the quality of the wireless communication network are improved.
Referring to fig. 5, in an embodiment, step S102 includes:
s201, judging whether a first change countdown corresponding to the first access point is larger than a second change countdown corresponding to the second access point;
s202, if the first change countdown corresponding to the first access point is greater than the second change countdown corresponding to the second access point, determining that the first access point meets a first preset rule.
In application, the first change countdown may or may not be equal to the second change countdown. In this embodiment, when the number of the second access points is less than 2, that is, the number of the second access points is 1, and when the first change count-down is greater than the second change count-down, it is determined that the first access point satisfies the first preset rule, and then the change stop frame is sent to the first access point.
In other applications, when the change countdown of the first AP1 is close to the change countdown of the second AP, for example, only the difference is 1, and the change countdown of the second AP2 is small, the change is completed first, then the time when the second AP2 completes the change and sends the change completion instruction to be received by the station apparatus STA1 is t1, and the time when the station apparatus STA1 sends the change stop frame to the first AP1 is t2, and the value of t1+ t2 may exceed the decay time of the change countdown corresponding to the first access point. That means, the first AP1 may also complete the color value change, which still causes the first AP1 to transmit the loss of the change declaration frame to the station STA1 during the change, and the AP1 also generates unnecessary change loss. The change declaration frame is used to indicate that the corresponding access point is in the process of changing the BSSColor value.
In this embodiment, when only BSS Color values of two access points collide, immediately transmitting the change stop frame to the access point with the larger change countdown period can prevent the first access point AP1 from still transmitting the change declaration frame to the station apparatus STA1 during the change period and prevent the AP1 from generating unnecessary change loss, and the collision can be solved by only requiring another second access point to change the BSS Color value, thereby improving the change efficiency and effectively reducing the power loss of changing the BSSColor value.
Referring to fig. 5, in an embodiment, after step S201, the method further includes:
s301, if the time of a first change countdown corresponding to the first access point is the same as the time of a second change countdown corresponding to the second access point, judging whether the changed BSS Color value corresponding to the first access point is the same as the changed BSS Color value corresponding to the second access point.
In the application, when the first change countdown time is the same as the second change countdown time, and the changed BSS Color value corresponding to the first access point is the same as the changed BSS Color value corresponding to the second access point, it means that the first access point and the second access point change to the same BSS Color value at the same time, that is, the Color value of the first access point and the Color value of the second access point collide again.
S302, if the changed BSS Color value corresponding to the first access point is the same as the changed BSS Color value corresponding to the second access point, the conflict report is sent to the first access point.
In application, if the changed BSS Color value corresponding to the first access point is the same as the changed BSS Color value corresponding to the second access point, a conflict report is sent to the first access point. Specifically, the first station can simultaneously receive and analyze the change management frame sent by the first access point and the change management frame sent by the second access point, and when the information of the two change management frames is found to be the same, namely the changed BSS Color value is the same and the timing is the same, a conflict report is sent to the first access point, so that the first access point can immediately resend the change management frame without waiting until the first change countdown attenuation is completed, and after the BSS Color value is changed, the changed BSS Color value is found to conflict again, and the change efficiency is improved.
In other applications, if the changed BSS Color values of the first access point and the second access point are the same and the changed BSS Color values are the same when the timing is changed, the first station device STA1 may also choose not to send a collision report to the first access point, the first access point maintains the changed BSS Color value, and the second station device STA2 sends a change stop frame to the second access point, so that the BSS Color value changed by the first access point after the first change countdown is attenuated may also be different from the BSS Color value changed by the second access point; or the second station device STA2 chooses not to send the collision report to the second access point and the station device STA1 sends the change stop frame to the first access point, which reduces the power consumption of the access point and the station device for sending/receiving unnecessary related change management frames, but is not limited thereto.
Referring to fig. 6, in an embodiment, step S103 includes:
s401, acquiring second change countdown in change management frames correspondingly sent by all the second access points.
S402, determining a third change countdown according to a second preset rule when all the second change countdown is performed.
S403, determining whether the third change countdown is less than the first change countdown.
S404, if the third change countdown is smaller than the first change countdown, determining that the first access point meets a first preset rule.
In an application, the number of the second access points is greater than or equal to 2, that is, a plurality of second change countdown corresponding to a plurality of second access points is performed. The third change countdown may be the change countdown with the smallest time among all the second change countdown, that is, the second predetermined rule may be one or more second change countdown finding the smallest or earliest time among all the second change countdown as the third change countdown. If STA1 can acquire the change management frame transmitted by AP2 and parse out that the corresponding second change countdown is "6", and if STA1 further acquires the change management frame transmitted by AP3 and parse out that the corresponding second change countdown is "7", it determines that the second change countdown corresponding to AP2 is the minimum change countdown, that is, the third change countdown.
In application, if the third change countdown is less than the first change countdown, it is determined that the first access point satisfies the first preset rule, and a collision report may be sent to the first access point, so that the first access point changes again and sends a change management frame, where the change management frame also includes the change countdown and the changed BSS Color value, that is, the changed BSS Color value. If STA1 determines that the second change countdown corresponding to AP2 is "6" as the third change countdown and STA1 receives the data frame transmitted by AP1 and resolves that the corresponding first change countdown is "8", then it determines that the third change countdown is less than the first change countdown and transmits a collision report to the first access point to cause the first access point to change again and transmit a change management frame.
In other applications, if the third change countdown is greater than the first change countdown, it means that the first access point will first complete the BSS Color value change, the first access point changes the BSS Color value according to the change countdown, and the second station devices corresponding to all the other second access points immediately and respectively send collision reports to the respective matched second access points.
In a specific application, when the number of the second access points is equal to two, the sizes of the second change countdown times corresponding to the two second access points are compared, the second change countdown time with the minimum time is selected as a third change countdown time, and the third change countdown time is compared with the change countdown time corresponding to the first access point. When the third change countdown is less than the first change countdown, the first access point is considered to meet the first preset rule, and since the changed BSS Color value of the first access point is changed and used earlier than the changed BSS Color value of the second access point corresponding to the third change countdown, a conflict report needs to be sent to the first access point to indicate the first access point to send the change management frame again, so that the changed BSS Color value is different from the changed BSS Color value corresponding to the second access point. In addition, other second access points receive the collision report sent by the station device matched with the second access point, such as the AP3 receives the collision report sent by the STA3 in the above application.
In this embodiment, when the BSS Color values changed by the N access points collide, all STAs with Color value collision do not need to correspondingly send collision reports to the access point, but the STA corresponding to the minimum change countdown does not need to send collision reports to the corresponding access point, and the access point corresponding to the minimum change countdown is maintained to continue changing. And the rest N-1 STAs send the conflict reports again to the corresponding access points to change the BSS Color value, so that the change efficiency is improved, and the change loss is reduced.
Referring to fig. 6, in an embodiment, after step S403, the method further includes:
s501, if the third change countdown is equal to the first change countdown, acquiring a second access point corresponding to the third change countdown;
and S502, if the changed BSS Color value corresponding to the first access point is the same as the changed BSS Color value corresponding to the second access point, sending the conflict report to the first access point.
In an application, there may be one or more minimum second change countdown (i.e., third change countdown) because there may be a plurality of second change countdown corresponding to the plurality of second access points, and the second change countdown may be the same for the second access points. Illustratively, if the number of the second change counts is two, and only one minimum second change count (i.e., the third change count) is provided, when it is determined that the changed BSS Color value of the second access point corresponding to the third change count is the same as the changed BSS Color value of the first access point, the collision report is immediately sent to the first access point, so that the first access point can quickly send the change management frame again, and the change efficiency is improved. At this time, whether the value of the BSS Color changed by the second access point is equal to the value of the BSS Color changed by the first access point or not may be maintained according to the second change countdown.
In an embodiment, step S403 is followed by:
and if the third change countdown is greater than the first change countdown and equal, receiving the changed BSS Color value maintained by the first access point according to the first change countdown.
In application, if the third change countdown is greater than the first change countdown, it means that the first access point will complete the BSS Color value change before the other access points in all the access points having the same BSS Color value, so that the first access point can maintain the change. Specifically, among the plurality of second change countdown timers, there are at least two minimum change countdown timers with the same countdown, for example, in the change management frames transmitted by the plurality of second access points (AP2 and AP3) acquired by STA1, if the change countdown corresponding to AP2 is "6" and the change countdown corresponding to AP3 is "7", it is determined that the change countdown corresponding to AP2 is the third change countdown, and if the corresponding change countdown is "5" in the change management frame transmitted by AP1 received by STA1, it represents that the access point transmitted by AP1 completes the BSS value change before AP2 and AP3, AP1 may maintain the BSS Color value change, and the other second station devices (STA2 and STA3) transmit a collision report to the corresponding second access points. Furthermore, when BSSColor values changed by N access points conflict, all STAs with Color value conflicts do not need to correspondingly send conflict reports to the access points, and if the STA corresponding to the minimum change countdown does not need to send the conflict reports to the corresponding access points, the rest N-1 STAs send the conflict reports to the corresponding access points again to change the BSSColor values, so that the change efficiency is improved, and the change loss is reduced.
In an embodiment, step S403 is followed by:
if the third change countdown is smaller than the first change countdown, acquiring a changed BSS Color value of an access point corresponding to the third change countdown, and writing the changed BSS Color value into a used Color value domain;
sending the collision report to the first access point, the collision report carrying the used color value range.
In application, the Color value field includes a plurality of different BSS Color values, and the BSS Color value may be considered as an identification number of a BSS, and a plurality of different BSSs may be formed when the wireless access point and the station device transmit a data frame, and in order to avoid communication interference between different BSSs, the same BSS Color value needs to be changed.
In application, when only one third change countdown is performed, the corresponding second access point will firstly complete the BSS Color value change, and place the changed BSS Color value into the used Color value field. The used Color value domain comprises BSS Color values used when all access points and corresponding site equipment transmit data frames at the current moment, when the first access point retransmits the change management frame, the changed BSS Color value contained in the first access point can select a Color value not in the used Color value domain, so that the changed BSS Color value is ensured to be different from the BSS Color value which is changed first, and the BSS Color values changed by the rest access points are prevented from conflicting with the BSS Color value changed by the second access point again.
In this embodiment, by receiving and analyzing change management frames sent by a first access point and a second access point having the same BSS Color value, when the number of the second access points is less than 2 and the first access point satisfies a first preset rule, a change stop frame is sent to the first access point, so as to avoid a situation that all the APs need to be changed when a plurality of BSS Color values conflict; and if the number of the second access points is more than or equal to 2 and the first access point meets a first preset rule, sending a conflict report to the first access point, so that only one AP is needed to change when the change countdown of the two BSSs is close to each other, and the change efficiency and the quality of the wireless communication network are improved.
