[0044] Figure 2 It is a structural schematic diagram of a transmission opportunity adjustment device provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0045] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0046] In order to facilitate those skilled in the art to understand the embodiments of the present invention, some terms are explained:

[0047] (1)AC: It is divided into four parts and four types: Best Effort (BE), Background (BK), Video (VI), and Voice (VO).

[0048] (2) Reverse protocol: Reverse Direction, RD protocol.

[0049] (3) TXOPlimit: Transmission opportunity limit time, specifically refers to the maximum length of time allocated by the AP to the STA to allow the STA to transmit on a specified specific AC.

[0050] like Figure 1 As shown, an embodiment of the present invention provides a method for adjusting a transmission opportunity, comprising:

[0051] Step S1: Obtaining the initial ratio of the default transmission opportunity restriction time of each AC to the total constraint time;

[0052] Specifically, the AP obtains an initial ratio of the default transmission opportunity restriction time of each AC of each STA to the total constraint time;

[0053] Each STA corresponds to four ACs with different priorities, namely BE, BK, VI, and VO.

[0054] The total constraint duration is the total length of the transmission opportunity restriction time of the four ACs of each STA, and the total constraint duration is a fixed value.

[0055] Furthermore, before the STA performs actual data transmission, the AP determines a default TXOP Limit for each AC of the STA according to the IEEE 802.11 default parameters.

[0056] Step S2: based on the real-time traffic status, obtaining the actual proportion of the actual transmission opportunity restriction time of each AC to the total constraint time;

[0057] Specifically, the AP counts the duration of traffic uploaded by each STA to each of its ACs within a period (the period can be adjusted or preset according to actual conditions);

[0058] Among them, if the AP needs to count the rate and limit time of each data frame, the amount of calculation will be too large; therefore, in an 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 the limit time of the data of each AC, but does not count the specific amount of information of the data.

[0059] Furthermore, the AP records the actual proportion of the traffic duration of each AC to the total constraint duration.

[0060] In an embodiment of the present invention, TXOP Limit is adjusted based on AP statistics to optimize the total throughput of data transmission corresponding to different ACs, thereby optimizing the total throughput of the system. Specifically, the actual proportion of the actual transmission opportunity limit time to be adjusted for each AC to the total constraint time based on the real-time traffic status is obtained, including:

[0061] Obtain the traffic duration required for the STA to upload data to each of the ACs;

[0062] The actual ratio of the traffic duration to the total constraint duration is obtained.

[0063] Step S3: comparing the actual ratio with the initial ratio, if the actual ratio is not equal to the initial ratio, determining the actual transmission opportunity limit time as the actual transmission opportunity limit time to be adjusted;

[0064] Specifically, if the actual ratio of the AC is equal to the initial ratio, the actual transmission opportunity limit time of the AC is not adjusted.

[0065] Step S4: adjust the actual transmission opportunity limit time to be adjusted of each AC, obtain updated actual transmission opportunity limit time, and then store the updated actual transmission opportunity limit time in Beacon or a management frame containing a Beacon field for broadcast announcement.

[0066] In an optional embodiment of the present invention, the adjusting the actual transmission opportunity limit time to be adjusted of each AC includes:

[0067] constructing a table based on the initial ratio and the actual ratio of each AC of the STA;

[0068] According to the table, the size relationship between the initial ratio and the actual ratio of each AC of each STA is determined.

[0069] Further, the table is a diagonal table, the columns of the diagonal table are used to fill in the initial proportion of each of the ACs; the rows of the diagonal table are used to fill in the actual proportion of each of the ACs;

[0070] The cells located on the diagonal line of the diagonal table are used to fill in the size relationship between the actual proportion and the initial proportion of each AC.

[0071] Among them, the table can be constructed in the following manner (in actual application scenarios, the actual ratio and the initial ratio can also be processed based on other forms, for example, constructing other forms of tables, etc.), an embodiment of the present invention is shown in the following Table 1:

[0072] First, fill in the table according to the diagonal table in Table 1 below (fill in the cells with "?"):

[0073] Table 1

[0074] A B C D A’ ？ / / / B’ / ？ / / C’ / / ？ / D’ / / / ？

[0075] Among them, A, B, C, and D in Table 1 refer to each AC respectively. Specifically, A refers to BK, B refers to BE, C refers to VI, and D refers to VO. The priorities of AC are from low to high.

[0076] As shown in Table 2 below, A, B, C, and D are the initial proportions of the four ACs; A', B', C', and D' are the actual proportions of each AC counted within a period of time.

[0077] For example, Table 2 can be filled with:

[0078] Table 2

[0079] A B C D A’ ＝ / / / B’ / > / / C’ / / > / D’ / / / <

[0080] Based on Table 2, we can see that A'=A; B'>B; C'>C; D' <D。

[0081] 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; and the actual proportion of VO is less than the initial proportion.

[0082] The total increase length of the AC's TXOP Limit that satisfies each of the STAs is equal to the total decrease length of the AC's TXOP Limit.

[0083] In an embodiment of the present invention, a diagonal table is constructed based on the actual ratio and initial ratio of each AC of the STA, and each cell on the diagonal in the diagonal table represents the size relationship between the actual ratio and the initial ratio of each AC; therefore, the size relationship between the actual ratio and the initial ratio of each AC can be intuitively obtained according to the constructed diagonal table.

[0084] Specifically, determining the relationship between the initial ratio and the actual ratio of each AC of each STA according to the table further includes:

[0085] 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 group of ACs;

[0086] Subtract N from the actual transmission opportunity limit time to be adjusted of each AC in the first group of ACs to obtain a first group of adjusted ACs; wherein the number of ACs included in the first group of ACs is a;

[0087] Wherein, a, N are integers greater than or equal to 0;

[0088] Add M to the actual transmission opportunity limit time to be adjusted for each AC in the second group of ACs to obtain the second group of adjusted ACs; where the number of ACs included in the second group of ACs is b;

[0089] where a * N = b * M.

[0090] b and M are integers greater than or equal to 0;

[0091] Further, (a, b) can be (1, 1), (1, 2), (1, 3) or (2, 2), etc. For example, based on Table 2, adjust the TXOPLimit length of ACs:

[0092] During the adjustment process, the principle to be followed is: Total increase in TXOP Limit = Total decrease in TXOP Limit; and since the field filled with TXOP Limit in the EEE 802.11 protocol is an integer and the unit is 32 μs; therefore, subsequent adjustments are made according to the increase and decrease of integers.

[0093] First, since A = A', the actual TXOP Limit corresponding to BK does not need to be adjusted;

[0094] Second, since B' > B, C' > C, D' < D, first subtract 1 from the actual TXOP Limit numbers corresponding to BE and VI (i.e., N = 1), and add 2 to the actual TXOP Limit number corresponding to VO (i.e., M = 2) (in order to satisfy that the total increase in TXOP Limit corresponding to the ACs with increased TXOP Limit = the total decrease in TXOP Limit corresponding to the ACs with decreased TXOP Limit).

[0095] It should be noted that both N and M are TXOP Limit indication coefficients, and TXOP Limit = indication coefficient * 32 μs.

[0096] In an optional embodiment of the present invention, the obtaining of the traffic duration required for the STA to upload data to each AC includes:

[0097] Count the number of times each AC shares the transmission opportunity using the reverse protocol.

[0098] Generally, when using the reverse protocol or TXOP sharing, it means that there is remaining time in the current TXOP for the current AC, that is: the TXOP Limit at that time is excessive for the data frames of the AC corresponding at that time; therefore, it is expected that during the next adjustment, the TXOP Limit lengths of these ACs with excessive TXOP Limit will be correspondingly reduced.

[0099] In the embodiment of the present invention, the actual proportion of ACs is adjusted secondary according to the counted lengths of reverse protocols and TXOP sharing used by each AC.

[0100] Specifically, counting the number of times each AC uses the reverse protocol to share the transmission opportunity includes:

[0101] Obtaining the number of times each of the ACs in the first group of adjusted ACs uses the reverse protocol to share the transmission opportunity;

[0102] Comparing the number of times each of the ACs in the first group of adjusted ACs uses the reverse protocol to share the transmission opportunity, and obtaining a comparison result;

[0103] Based on the comparison result, an actual transmission opportunity limit time of each of the ACs in the first group of adjusted ACs is adjusted.

[0104] Further, the adjusting the to-be-adjusted actual transmission opportunity limit time of each of the ACs in the first group of adjusted ACs based on the comparison result includes:

[0105] Subtract E from the actual transmission opportunity limit time to be adjusted of the AC that shares the reverse protocol with the transmission opportunity more times; wherein the number of the ACs that share the reverse protocol with the transmission opportunity more times is c;

[0106] Add F to the actual transmission opportunity limit time to be adjusted of each AC in the second group of adjusted ACs;

[0107] Among them, c*E=b*F.

[0108] c, E, and F are integers greater than or equal to 0.

[0109] For example, adjust the TXOP Limit length of the AC in Table 2 twice:

[0110] First, the number of times B' and C' use the reverse protocol and TXOP sharing (denoted as T) is compared, and for the AC with the larger number, 1 is subtracted.

[0111] Assume that the corresponding T(B) of B' is 3, the corresponding T(C) of C' is 1, and T(B)>T(C); then the actual TXOP Limit of the adjusted B' is reduced by 1.

[0112] In addition, the adjusted actual TXOP Limit corresponding to D' is increased by 1 (the total increase in TXOP Limit corresponding to the AC with increased TXOP Limit=the total decrease in TXOP Limit corresponding to the AC with decreased TXOP Limit).

[0113] The above embodiments of the present invention may be implemented based on the following implementations (in actual application scenarios, they may also be implemented based on other implementations, which are not specifically limited in the embodiments of the present invention):

[0114] Specifically, in an actual application scenario, for example, the initial TXOP Limit lengths of four ACs are:

[0115] BK's TXOP Limit = 2.528;

[0116] BE's TXOP Limit = 2.528;

[0117] VI's TXOP Limit = 4.096;

[0118] VO TXOP Limit = 2.080;

[0119] Since TXOP Limit is an integer multiple of 32μs, the default TXOP Limits of BK, BE, VI, and VO are all integers, namely 79, 79, 128, and 65 respectively.

[0120] If A=BK, B=BE, C=VI, and D=VO, the adjusted TXOP Limit numbers are 79, 77 (79-2), 127 (128-1), and 68 (65+3).

[0121] For the four ACs of a STA, the total constraint time to meet its TXOP Limit remains unchanged, but the proportion of each internal AC is adjusted.

[0122] In an optional embodiment of the present invention, if the reverse protocol of each AC in the first group of adjusted ACs is shared with the same number of transmission opportunities, no secondary adjustment is performed.

[0123] Therefore, the embodiments of the present invention can optimize the flow limits of different services in the network within the same time period to achieve better throughput and shorter access delay.

[0124] After the adjustment is completed, the AP announces the new EDCA parameter set and starts a new round of statistics.

[0125] like Figure 2 The embodiment of the present invention further provides a transmission opportunity adjustment device 200, comprising:
