Description

Background

In the existing wlan technology, in an environment of deploying Access Points (APs) at high density, Basic Service Sets (BSSs) corresponding to the APs may overlap, that is, more Overlapping Basic Service Sets (OBSSs) may exist, which means that more communication collisions may occur. Therefore, in the wlan standard, a basic service set coloring mechanism (BSS coloring) is adopted, and different BSS colors (BSS colors) are marked for each BSS in the OBSS to avoid communication collisions between different BSSs, enhance channel reuse rate, and reduce interference of adjacent networks.

However, since the value of BSS Color is limited, there may be a case where BSS Color conflicts (i.e., BSS Color values are repeated) in the same OBSS. In the prior art, when there is a BSS Color conflict, each AP having the conflict performs a BSS Color value changing operation independently, but the changing method of the BSS Color value is inefficient.

At present, due to the limited value of BSS Color (usually an integer in the range of 1 to 63), there may be BSS Color collision (i.e. repeated BSS Color values) in the same OBSS. In the prior art, when there is a BSS Color conflict, each AP in conflict performs a BSS Color value change operation independently. However, there may be redundant changes in the BSS Color value, which results in inefficient methods for changing the BSS Color value.

In order to solve the technical problem, embodiments of the present application provide a basic service set management method, a communication device, and a storage medium, where when a first AP detects a BSS Color conflict, a BSSID of a basic service set identifier of each AP in an AP set of the detected BSS Color conflict is obtained first, and a sequence is performed according to the BSSID of each AP in the AP set, so as to determine a sequence position corresponding to the first AP. And when the sequencing position corresponding to the first AP is determined to meet the first preset condition, changing the BSS Color value of the first AP. The first AP can determine that the sequencing position of the first AP accords with a first preset condition according to the result obtained by sequencing each AP according to the BSSID in the AP set, and then changes the BSS Color value, so that the first AP can synthesize BSSID information in the AP set to realize coordination with other APs, redundant change or repeated change of the BSS Color is avoided, operation cost and communication cost are reduced, network throughput is improved, and change efficiency of the BSS Color value is improved.

The first embodiment is as follows:

fig. 1 shows a flowchart of a basic service set management method provided in an embodiment of the present application, where an execution subject in the embodiment of the present application is a first AP. In a wireless communication network, each BSS includes an AP and may further include a Station (STA), and the AP performs BSS Color collision monitoring and changing of the BSS; the first AP in the embodiment of the present application may be any AP in a wireless communication network. The basic service set management method as shown in fig. 1 is detailed as follows:

in S101, if BSS Color conflict is detected, BSSIDs of all APs in an AP set corresponding to the BSS Color conflict are obtained; wherein the set of APs includes the first AP.

In OBSS, data within each BSS is identified and distinguished by its respective BSS Color value. Specifically, a physical layer protocol data unit (PPDU) sent by an AP or an STA in each BSS carries a BSS Color value of the BSS, so that the APs or STAs in other BSSs can identify whether the PPDU is from a BSS where the PPDU is located according to the BSS Color value.

And if the first AP receives the PPDU from the OBSS STA on the main channel of the first AP and analyzes and determines that the BSS Color value carried by the PPDU is consistent with the BSS Color value of the first AP, judging that the current first AP detects BSS Color conflict.

And determining an AP set according to the BSS Color conflict, wherein the AP set comprises the first AP and other APs detected by the first AP and having the same BSS Color value as that of the first AP.

And acquiring the BSSID of the basic service set unique identifier of each AP in the AP set. In one embodiment, the BSSID of each AP may be resolved from the PPDU. The BSSID of the first AP itself may be acquired from its own storage unit. Through the foregoing method, BSSIDs of respective APs in the AP set can be obtained.

In S102, sorting is performed according to BSSIDs of the APs in the AP set, and a sorting position corresponding to the first AP is determined.

After the BSSID of each AP in the AP set is obtained, the APs are sequenced according to the sequence from large to small or from small to large according to the value of the BSSID of each AP, and therefore the sequencing position corresponding to the first AP is obtained.

In S103, if the sorting position corresponding to the first AP meets a first preset condition, the BSS Color value of the first AP is changed.

In this embodiment of the application, the first preset condition may be that the sorting position corresponding to the first AP is a non-designated bit position. The designated bit position may be a first position or a last position sorted according to the value of the BSSID, and correspondingly, the non-designated bit position is a non-first position or a non-last position. The designated bit position may be determined in advance by a preset rule.

In one embodiment, if the AP set includes N APs, when a BSS Color conflict occurs, the AP set only needs (N-1) APs to change the BSS Color value, so as to resolve the conflict; wherein N is a positive integer greater than or equal to 2. Therefore, in the rule preset in advance, a unique position can be designated as the designated bit position, one AP in the designated bit position does not need to change the BSS Color value, and the remaining (N-1) APs in the non-designated bit positions need to change the BSS Color value.

And when the sequencing position corresponding to the first AP is detected to be the designated bit position in the preset rule, maintaining the BSS Color value of the first AP unchanged. On the contrary, when it is detected that the sorting position corresponding to the first AP is the non-designated bit position, it is determined that the sorting position corresponding to the first AP meets the first preset condition, and the BSS Color value of the first AP is changed.

In the embodiment of the application, when a first AP detects a BSS Color conflict, a BSSID of a basic service set identifier of each AP in an AP set of the detected BSS Color conflict is obtained first, and sequencing is performed according to the BSSID of each AP in the AP set, so that a sequencing position corresponding to the first AP is determined. And when the sequencing position corresponding to the first AP is determined to meet the first preset condition, changing the BSS Color value of the first AP. The first AP can determine that the sequencing position of the first AP accords with a first preset condition according to the result obtained by sequencing each AP according to the BSSID in the AP set, and then changes the BSS Color value, so that the first AP can synthesize BSSID information in the AP set to realize coordination with other APs, redundant change or repeated change of the BSS Color is avoided, operation cost and communication cost are reduced, network throughput is improved, and change efficiency of the BSS Color value is improved.

Optionally, the first preset condition in step S103 is determined by current time information.

The unit of the time information in the embodiment of the present application may be day or time. For example, the time information may be indicative of the current day of the year or month, or may be indicative of the current hour of the day.

In the embodiment of the present application, the current first preset condition may be specifically determined according to the current time information. Specifically, the current designated position setting rule may be determined according to the current time information, and then the current first preset condition may be determined. In one embodiment, when the time information is odd, the designated bit position is set as a position corresponding to the maximum value of the BSSID, that is, the first bit position after descending sorting, or the last bit position after ascending sorting is set as the designated bit position; the first preset condition is that the first AP is a non-first position in descending order sorting or a non-last position after ascending order sorting, that is, the BSSID value of the first AP is a non-maximum value; and when the time information is even, the designated position is set as the position corresponding to the minimum value of the BSSID, and correspondingly, when the BSSID value of the first AP is not the minimum value, the corresponding sequencing position accords with a first preset condition. Or, conversely, when the time information is odd, the designated position is the position corresponding to the BSSID minimum value; when the time information is even, the designated position is a position corresponding to the maximum BSSID value.

In the embodiment of the application, the first preset condition can be determined by combining the current time information, so that the situation that an AP (for example, a first AP or a last AP) in a unique position does not change the BSS Color value for a long time and other APs need to frequently change the BSS Color value can be avoided, the fairness and the balance of basic service set management are improved, and the running stability of each AP is ensured.

and sequencing all the APs in the AP set according to the mapped BSSIDs corresponding to all the APs, and determining the sequencing position corresponding to the first AP.

In the embodiment of the application, in order to further balance the probability of each AP performing a BSS Color change operation, the BSSID is determined and mapped according to the current time information, and then the APs are sequenced.

Specifically, the mapped BSSID in the embodiment of the present application is a value obtained by adding a certain offset to a value of the BSSID based on the current time information. This mapped BSSID may be referred to as a TIME-based BSSID value (TB _ BSSID). In one embodiment, the BSSID is a value expressed by a length of 6 bytes, and the value of the mapped BSSID can be calculated by the following formula:

TB_BSSID＝BSSID+TIME×[ID_offset 0 0 0 0 0]

in the above equation, TB _ BSSID is mapped BSSID, ID _ offset is a value of one byte length, the value is an offset for dynamically adjusting the TB _ BSSID value, and the size of the value can be determined according to actual needs; each "0" value of the above equation is also one byte in length. TIME may take the last bit of the current TIME value, or the last two bits, etc., and may be set according to the value of ID _ offset. For example, if the value of ID _ offset is 30, the TIME takes the last bit of the current TIME value, that is, the TIME value range is 0 to 9; and if the value of the ID _ offset is 0-9, taking the last two bits of the current TIME value by TIME. Specifically, the ranges of ID _ offset and TIME are satisfied by TIME x [ ID _ offset 00000 ]]The value range of the later step is close to 0-2⁸1, i.e. exceeding the maximum offset amount close to 255, substantially covers the region from the minimum value to the maximum value, so that BSSID is increased by TIME x [ ID _ offset 00000 ]]The resulting TB _ BSSID may have a different size ordering than the original BSSID due to data bit overflow (e.g., the original AP with the maximum BSSID in the AP set, plus TIME x ID _ offset 00000]The resulting value becomes the minimum value in the AP set).

After the mapped BSSID of each AP in the AP set is determined based on the time information, the APs are sequenced according to the mapped BSSID corresponding to the APs, and therefore the sequencing position corresponding to the first AP is determined.

In the embodiment of the application, because the mapped BSSIDs of the APs at the current time can be re-determined based on the time information and the BSSIDs of the APs, the APs are sequenced according to the mapped BSSIDs, and the sequencing positions of the APs at different times are different, the probability of the APs executing the BSS Color change operation can be further balanced, the fairness and the balance of basic service set management are improved, and the running stability of the APs is ensured.

Optionally, the changing the BSS Color value of the first AP includes:

In the embodiment of the application, after sequencing all the APs in the AP set according to the BSS BSSID values of all the APs, specifically, after sequencing the APs needing to change the BSS Color value in the AP set, the BSS Color value is sequentially changed according to the sequencing positions of the APs in the AP set. For the first AP, if the first AP meets the first preset condition and is the first AP in the sequence, the operation of changing the BSS Color value of the first AP is directly performed. If the first preset condition is met, but other APs exist before the first AP in the sequence, the first AP performs the operation of changing the BSS Color value of the first AP when detecting that the second AP has completed the change of the BSS Color value. And the second AP is an AP of which the sequencing position is positioned before the sequencing position of the first AP after the AP set is sequenced. In one embodiment, when a PPDU with a BSSID of the second AP being the BSSID value is received and it is detected that a BSS Color carried in the PPDU has changed, it is determined that the second AP has completed the change of the BSS Color.

In one embodiment, after detecting that the second AP has completed the BSS Color change, the first AP obtains the latest BSS Color values changed by the APs located before the first AP sorting position, and identifies the latest BSS Color values as the non-selectable BSS Color values. And then, selecting a BSS Color value from the BSS Color values which are not identified as non-selectable as a new BSS Color value to be changed by the current first AP, and executing corresponding change operation.

In the embodiment of the application, when the first AP determines that the first AP needs to change the BSS Color, the first AP further executes the BSS Color change of the first AP after waiting for the second AP located in front of the first AP to finish the BSS Color change on the basis of the sequencing of the BSSID values, so that the BSS Color change can be finished in sequence, and BSS Color conflict is avoided after the BSS Color is changed.

Optionally, the changing the BSS Color value of the first AP further includes:

In general, a first AP needs to wait until a second AP which is sequenced before the first AP and meets a first preset condition completes a BSS Color value change and then performs a BSS Color change operation, so as to avoid repeated changes of the BSS Color value. However, when the second AP does not complete the BSS Color change in time, if the AP fails, the first AP does not detect that the second AP completes the BSS Color value change within the preset waiting time, and then directly executes the BSS Color value change operation of the first AP, thereby ensuring that the BSS Color value of the first AP can be changed in time under abnormal conditions.

Optionally, the method further comprises:

In the embodiment of the present application, in the OBSS, there may be some cases where BSS Color conflicts cannot be detected by the first AP. The STA that establishes a communication connection with the first AP may obtain, according to the BSSID value and the BSS Color value of the received PPDU, a BSS Color collision that cannot be detected by the first AP. If the BSS Color conflict exists and the first AP meets the first preset condition, the STA sends change indication information to the first AP. And the first AP executes the BSS Color changing operation after receiving the changing instruction information.

In the embodiment of the present application, the first AP can perform BSS Color change operation in time by receiving change instruction information sent by the STA, by using the associated STA, in addition to the determination of the first AP, when there is BSS Color conflict but the first AP cannot detect the BSS Color conflict.

Optionally, the changing the BSS Color value of the first AP includes:

In the embodiment of the application, after determining that the sequencing position corresponding to the first AP accords with the first preset condition, the first AP determines a new BSS Color value which needs to be changed. Specifically, the first AP selects one BSS Color value from the selectable BSS Color values as the BSS Color value of the first AP. The optional BSS Color value is the remaining BSS Color value except for the selected BSS Color values of other APs ordered before the first AP.

After determining the new BSS Color value, a change notification message carrying the new BSS Color value may be generated according to the new BSS Color value. And then, the change notification message is sent to the STAs associated with the first AP, so that the STAs can timely know the BSS Color value change condition of the first AP, and subsequently can judge which PPDUs are from the data sent in the associated BSS according to the changed BSS Color value.

In one embodiment, the Change notification message is a frame carrying a Change notification element (BSS Color Change notification element), and may be, for example, a Beacon frame (Beacon), a Probe Response frame (Probe Response), an Association Response frame (Association Response), a ReAssociation Response frame (ReAssociation Response), or the like, which carries the Change notification element.

The format of the change notification element described above is as follows:

the change notification element, in turn, includes 6 fields, each of a length of one byte. The Element ID field is used for storing an identification number of the current change notification Element, and the Length field is used for storing a valid data bit of the change notification Element, specifically, the total Length of a field located after the Length field; the Element ID Extension field is identification number Extension information used for storing change notification elements; a Color Switch count down field for storing a Countdown time for BSS Color change completion, i.e., for indicating how many Target Beacon Transmission Times (TBTTs) the new BSS Color value will take effect since the frame carrying the change notification element is sent; a New BSS Color information field is used to store a New BSS Color value to be used.

In the change notification element, the color switch countdown field is 1 byte long, the transmission interval Beacon interval of each Beacon is two bytes long, and the transmission interval of the general Beacon is 100 in 1024 microseconds, then the color switch countdown field is set to the maximum value 255, which can indicate the maximum value of time: 255 x 100 x 1024 is about 26112000 microseconds, which is about 26 seconds, so the time unit of the current time information should not adopt minutes, but can adopt a value which is greatly different from 26 seconds such as days or time, and the like, and thus, the case that the change time of the BSS Color spans two time units is not basically involved, namely, the probability of rule change during the change of the BSS Color is low.

Example two:

fig. 2 shows a schematic flow chart of a basic service set management method provided in an embodiment of the present application, where an execution subject in the embodiment of the present application is an STA, and the basic service set management method shown in fig. 2 is detailed as follows:

in S201, if a BSS Color collision is detected, BSSIDs of APs in an AP set in which the BSS Color collision occurs are acquired.

In the embodiment of the application, the STA acquires a PPDU sent in the OBSS, and if the PPDU corresponding to different BSSID values carries the same BSS Color value in the PPDU sent in the OBSS, it is determined that a BSS Color conflict currently exists, and an AP corresponding to the part of BSSID values where the conflict exists is determined as an AP set.

For each AP in the AP set, the STA may determine the BSSID corresponding to each AP according to address information carried in a PPDU sent in the OBSS.

In S202, the APs are ranked according to BSSIDs of the APs in the AP set, and ranking positions of the APs are determined.

After the BSSID of each AP in the AP set is obtained, the APs are sequenced according to the sequence from large to small or from small to large according to the value of the BSSID of each AP, and therefore the sequencing position corresponding to each AP in the AP set is obtained.

In S203, change instruction information is sent to the AP whose ranking position meets a first preset condition and is associated with the STA.

The first preset condition in the embodiment of the present application is the same as the first preset condition in the previous embodiment. The STAs are capable of data communication with their associated APs. And after determining the sequencing position corresponding to each AP, sending change indication information to the APs which accord with the first preset condition (namely are located at the non-designated bit positions) and are associated with the STA, and indicating the APs to change the BSS Color in time.

Optionally, the method further comprises:

and receiving a change notification message sent by the AP.

The definition of the change notification message is consistent with that of the previous embodiment. After the change notification message sent by the AP is obtained, the data subsequently sent by the AP can be accurately identified according to the new BSS Color value carried in the change notification message, so as to implement accurate data communication with the AP.

In the embodiment of the application, because the STA is used as a device for communicating with the AP, BSS Color conflict detection can be performed, and when a conflict is detected, the STA performs sequencing according to BSSIDs of the APs in the AP set, determines the sequencing position of each AP, and sends change instruction information to the AP which meets the first preset condition and is associated with the STA, so that the AP is notified of the change of the BSS Color value in time, the relationship among the APs can be coordinated, the repeated change of the BSS Color is avoided, and the change efficiency of the BSS Color value is improved.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
