Detailed ways

The following describes in detail the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, some terms are explained:

(1) AC: Divided into BestEffort (BE), Background (BK), Video (VI), Voice (VO) four parts, four types.

(2) Reverse protocol: Reverse Direction, RD protocol.

(3) TXOPlimit: transmission opportunity limit time, which specifically refers to the maximum length of time allocated by the AP to the STA to allow the STA to transmit the specified specific AC.

As shown in FIG. 1 , an embodiment of the present invention provides a method for adjusting a transmission opportunity, including:

Step S1: Obtain the initial ratio of the default transmission opportunity restriction time of each AC to the total restriction time;

Specifically, the AP obtains the initial ratio of the default transmission opportunity restriction time of each AC of each STA to the total restriction time;

Among them, each STA corresponds to four ACs with different priorities, namely BE, BK, VI, and VO.

The total constraint duration is the total duration of the transmission opportunity restriction time of the 4 ACs of each STA, and the total constraint duration is a fixed value.

Further, before the STA performs actual data transmission, the AP determines the default TXOP Limit of each AC of the STA according to IEEE 802.11 default parameters.

Step S2: obtaining the actual ratio of the actual transmission opportunity restriction time of each AC to the total restriction time duration based on real-time traffic conditions;

Specifically, the AP counts the duration of the traffic uploaded by each STA to each of its own ACs within a period of time (the period of time can be adjusted or preset according to the actual situation);

Among them, if the AP needs to count the rate and limit time of each data frame, the amount of calculation is too large; therefore, in the embodiment of the present invention, in order to reduce the burden on the AP, the AP is only responsible for limiting the TXOP Limit, that is, the AP only counts each data frame. The time limit of the AC data is not the specific information size of the statistical data.

Further, the AP records the actual proportion of the traffic duration of each AC to the total constraint duration.

In the embodiment of the present invention, the TXOP Limit is adjusted based on AP statistics, so as to optimize the total throughput of data transmission corresponding to different ACs, thereby optimizing the total system throughput. Specifically, obtaining the actual proportion of the actual transmission opportunity restriction time to be adjusted of each AC to the total restriction time duration based on the real-time traffic conditions includes:

Obtain the traffic duration required by the STA to upload data to each AC;

Obtain the actual proportion of the traffic duration to the total constraint duration.

Step S3: Compare the actual ratio with the initial ratio, and if the actual ratio is not equal to the actual ratio, determine the actual transmission opportunity restriction time as the actual transmission opportunity restriction time to be adjusted;

Specifically, if the actual ratio of the AC is equal to the initial ratio, the actual transmission opportunity restriction time of the AC is not adjusted.

Step S4: Adjust the actual transmission opportunity limit time to be adjusted of each AC, obtain and update the actual transmission opportunity limit time, and then store the updated actual transmission opportunity limit time in a Beacon or a management frame containing a Beacon field broadcast announcement.

In an optional embodiment of the present invention, the adjusting the actual transmission opportunity limit time to be adjusted of each AC includes:

constructing a table based on the initial scale and the actual scale of each of the ACs of the STA;

According to the table, the magnitude relationship between the initial ratio and the actual ratio of each of the ACs of each of the STAs is determined.

Further, the table is a diagonal table, and the columns of the diagonal table are used to fill in the initial ratio of each of the ACs; the rows of the diagonal table are used to fill in the initial ratio of each of the ACs. actual proportion;

Cells located on the diagonal of the diagonal table are used to fill in the magnitude relationship between the actual scale and the initial scale for each of the ACs.

Among them, the table can be constructed as follows (in the actual application scenario, the actual ratio and the initial ratio can also be processed based on other forms, such as: constructing other forms of tables, etc.), the embodiment of the present invention, as shown in Table 1 below :

First, fill out the table (fill the cells with "?" in the diagonal form of Table 1 below):

Table 1

A B C D A’ ? / / / B’ / ? / / C’ / / ? / D’ / / / ?

Among them, A, B, C, and D in Table 1 refer to each AC, specifically, A refers to BK, B refers to BE, C refers to VI, D refers to VO, and the priority of AC From low to high.

A, B, C, and D in Table 2 below are the initial proportions of the four ACs, respectively; A', B', C', and D' are the actual proportions of each AC counted within a period.

For example: Table 2 can be populated as:

Table 2

A B C D A’ = / / / B’ / > / / C' / / > / D’ / / / <

Based on Table 2, A'=A; B'>B; C'>C; D'<D.

Then, the actual proportion of BK is equal to the actual proportion; the actual proportion of BE is greater than the initial proportion; the actual proportion of VI is greater than the initial proportion; the actual proportion of VO is less than the initial proportion.

The total increase length to satisfy the AC's TXOP Limit for each of the STAs is equal to the AC's total decrease in TXOP Limit length.

In this embodiment of the present invention, a diagonal table is constructed based on the actual scale and initial scale of each AC of the STA, and each cell on the diagonal in the diagonal table represents the size of the actual scale and the initial scale of each AC relationship; therefore, the actual scale of each AC and the size relationship of the initial scale can be intuitively obtained according to the constructed diagonal table.

Specifically, according to the table, determining the size relationship between the initial ratio and the actual ratio of each AC of each STA further includes:

All the ACs whose actual ratio is greater than the initial ratio form a first group of ACs, and all the ACs whose actual ratio is less than the initial ratio form a second set of ACs;

Subtract N from the actual transmission opportunity limit time to be adjusted of each of the ACs in the first group of ACs to obtain a first group of adjusted ACs; wherein the number of the ACs included in the first group of ACs is a;

Among them, a, N are integers greater than or equal to 0;

Add M to the to-be-adjusted actual transmission opportunity limit time of each of the ACs in the second group of ACs to obtain a second group of adjusted ACs; wherein the number of the ACs included in the second group of ACs is b;

where a*N=b*M.

b, M is an integer greater than or equal to 0;

Further, (a, b) can be (1, 1), (1, 2), (1, 3) or (2, 2) and the like. For example, adjust the AC's TXOPLimit length based on Table 2:

In the process of adjustment, the principle to be followed is: the total increase of TXOP Limit = the total decrease of TXOP Limit; and since the EEE 802.11 protocol requires that the field filled in TXOP Limit is an integer, and the unit is 32 μs; therefore, subsequent adjustments are based on Integer increase or decrease to adjust.

First, since A=A', the actual TXOP Limit corresponding to BK does not need to be adjusted;

Secondly, since B'>B, C'>C, D'<D, first subtract 1 from the actual TXOP Limit corresponding to BE and VI (that is, N=1), and add 1 to the actual TXOP Limit corresponding to VO. 2 (that is, M=2) (to meet the total increase in TXOP Limit corresponding to ACs with increased TXOP Limit = total decrease in TXOP Limit corresponding to ACs with decreased TXOP Limit).

It should be noted that N and M are both TXOP Limit indication coefficients, and TXOP Limit=indication coefficient*32μs.

In an optional embodiment of the present invention, the obtaining the traffic duration required by the STA to upload data to each AC includes:

The number of times that each AC uses the reverse protocol to share the transmission opportunity is counted.

Generally, when the reverse protocol or TXOP sharing is used, it means that the current AC has remaining time in the current TXOP, that is, the TXOP Limit at that time is too much for the data frame of the corresponding AC at that time; therefore, it is expected that In the next adjustment, reduce the TXOP Limit length of these ACs with excessive TXOP Limit accordingly.

In the embodiment of the present invention, according to the counted length of each AC using the reverse protocol and the TXOP, the actual proportion of the AC is adjusted twice.

Specifically, the counting the times that each AC uses the reverse protocol to share the transmission opportunity, including:

obtaining the number of times that each AC of the first group of adjustment ACs uses the reverse protocol to share the transmission opportunity;

Comparing the number of times that each AC of the first group of adjustment ACs uses the reverse protocol to share the transmission opportunity, and obtains a comparison result;

Based on the comparison result, the actual transmission opportunity limit time of each of the ACs of the first set of adjustment ACs is adjusted.

Further, the adjusting, based on the comparison result, the actual transmission opportunity limit time to be adjusted of each of the ACs in the first group of adjustment ACs includes:

Decrease E from the actual transmission opportunity limit time to be adjusted of the AC that has shared the reverse protocol and transmission opportunities more times; wherein, the AC that has shared the reverse protocol and transmission opportunities more times The number is c;

adding F to the to-be-adjusted actual transmission opportunity limit time of each of the ACs of the second group of adjustment ACs;

where c*E=b*F.

c, E, and F are integers greater than or equal to 0.

For example: make a secondary adjustment to the TXOP Limit length of the AC in Table 2:

First, compare the times of B' and C' using the reverse protocol and TXOP sharing (denoted as T), and then subtract 1 for the AC with more times.

Assuming that the corresponding T(B) of B'=3, the corresponding T(C) of C'=1, and T(B)>T(C); then the actual TXOP Limit of the adjusted B' is decremented by 1.

In addition, add 1 to the adjusted actual TXOP Limit corresponding to D' (the total increase in TXOP Limit corresponding to the AC whose TXOP Limit is increased = the total decrease in TXOP Limit corresponding to the AC whose TXOP Limit is decreased).

The above-mentioned embodiments of the present invention can be implemented based on the following implementations (in practical application scenarios, they can also be implemented based on other implementations, which are not specifically limited in the embodiments of the present invention):

Specifically, in practical application scenarios, for example, the specific lengths of the initial TXOP Limits of the four ACs are:

BK's TXOP Limit=2.528;

BE's TXOP Limit=2.528;

VI's TXOP Limit=4.096;

VO's TXOP Limit=2.080;

Since the TXOP Limit is an integer multiple of 32μs, the default TXOP Limits of BK, BE, VI, and VO are all integers, which are 79, 79, 128, and 65, respectively.

If corresponding to A=BK, B=BE, C=VI, D=VO, the adjusted TXOP Limit numbers are 79, 77 (79-2), 127 (128-1), and 68 (65+3).

For the four ACs of the STA, the total constraint duration for satisfying the TXOP Limit is unchanged, but the proportion of internal ACs is adjusted.

In an optional embodiment of the present invention, if the number of times the reverse protocol and the transmission opportunity of each of the ACs in the first group of adjustment ACs are shared is the same, no secondary adjustment is performed.

Therefore, the embodiments of the present invention can optimize the traffic restrictions of different services in the network within the same time period, so as to achieve better throughput and shorter access delay.

After the adjustment, the AP announces the new EDCA parameter set, and then starts a new round of statistics.
