Description

Technical Field

[0001] The present invention belongs to the field of network technology, and in particular relates to a method, device, equipment and storage medium for scheduling transmission opportunities. Background Art

[0002] In the Hybrid Coordination Function (HCF) Controlled Channel Access (HCCA) scenario of the Medium Access Control (MAC) layer of the IEEE (Institute of Electrical and Electronics Engineers) 802.11 protocol, the Access Point (AP) polls to allocate HCCA Transmission Opportunities (TXOPs) to the Stations (STAs) within the current Basic Service Set (BSS) to provide them with opportunities to access the channel for data transmission; and if an STA feels that the TXOP allocated by the current AP to itself is not enough, it can apply to the AP for a period of TXOP. However, the AP may not necessarily allocate or may not allocate in full, mainly depending on the AP side.

[0003] However, the IEEE 802.11 protocol does not stipulate the algorithm for the AP to allocate HCCA TXOPs to the STAs that request TXOPs, and in the process of solving the above problems, the prior art only considers the traffic level and requirements on the terminal side, without considering the resource situation on the AP side (or the STA side); in many cases, the resources on the AP side are likely to be limited (at least limited within a certain period of time), which needs to be considered comprehensively; the prior art does not consider the data life cycle on the STA side, and this life cycle will affect the packet survival rate. Once the life cycle is exceeded, the corresponding packet is lost. In addition, the prior art only considers the average data volume and the data volume to be sent (the current situation) for scheduling, without considering the historical scheduling situation. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems in the related art to some extent. For this purpose, an object of the present invention is to provide a method, device, equipment and storage medium for scheduling transmission opportunities.

[0028] Send a request to the AP to obtain an HCCA TXOP;

[0029] Receive the HCCA TXOP allocated by the AP;

[0030] Monitor the valid time of the life cycle of the data to be sent;

[0031] When the valid time is less than the third preset threshold, send a QoS frame to the AP.

[0032] Optionally, the QoS frame carries information on a TXOP duration request.

[0033] Optionally, the step of monitoring the valid time of the life cycle of the data to be sent further includes:

[0034] Monitor the valid time of the life cycle of the data to be sent to obtain the valid time;

[0051] The embodiment of the present invention has the following technical effects:

[0052] The above technical solution of the present invention: 1) provides a scoring system for the HC in the AP. For the STA that has submitted an HCCATXOP application, this system can be used to provide an evaluation result, and then determine whether it is necessary to allocate HCCATXOP to the STA and how much HCCATXOP to allocate; moreover, the scoring system integrates multiple dimensions, making the evaluation result more reasonable; the dimensions involved mainly include two major aspects: the resources of the HC and the resources of the STA; among them, the resources of the HC in the AP include the remaining available HCCATXOP length and the HCCATXOP resources that have been actively polled / assigned to the STA; the resources of the STA include the life cycle of the data packets queued by itself, and this life cycle is closely related to the storage capacity of the STA itself and the packet inventory time; when the remaining life cycle of the data packet is relatively short, it can be considered that the AP should allocate resources to this STA as soon as possible to reduce the probability of data packet loss.

[0053] 2) The process of allocating HCCATXOP is a process of resource integration and allocation. Therefore, in this process, it is a very appropriate approach to consider the resource situations of both the HC in the AP and the STA; in traditional resource allocation strategies, usually only the AP side considers its own resource situation without the information reported by the STA. The embodiments of the present invention add a link for the STA to report information, which is more conducive to the AP side to measure the resource allocation strategy.

[0054] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0060] For the convenience of those skilled in the art to understand the embodiments, some terms are explained as follows:

[0061] (1) HC: hybrid coordinator, the central coordinator, specifically refers to the central coordinator that allocates HCCATXOP to the STA in HCCA. The function of the HC is usually completed by the AP. Therefore, it can be considered that the HC function is integrated in the AP; that is, the process of the AP mentioned in the embodiments of the present invention allocating HCCA TXOP to the STA is based on the execution of the HC.

[0062] (2) QoS: Quality of Service, quality of service.

[0063] (3) Info: status statistical information.

[0064] (4) Request: request.

[0065] (5) CAP: controlled access phase, controlled access phase.

[0066] (6) Control field: control field.

[0067] (7) Duration Requested: duration requested.

[0068] (8) TBTT: target beacon transmission time interval.

[0069] (9) Beacon: beacon.

[0070] As Figure 1 shown, the embodiments of the present invention provide a method for scheduling transmission opportunities, which is applied to the AP and includes:

[0071] Step S11: Receive a request from the STA to obtain HCCA TXOP;

[0072] Specifically, the AP needs to set the TXOP Request bit in the QoS Info sent by itself to 1, indicating that the current AP can process the TXOP Request proposed by the STA.

[0073] Therefore, the AP mentioned in the embodiments of the present invention is an AP capable of processing TXOP Request for the STA.

[0074] Step S12: Generate a scoring parameter based on the request;

[0075] Specifically, the generating a scoring parameter based on the request includes:

[0076] Determine the number of times the STA has been actively polled within the current CAP, and generate a first parameter;

[0077] Wherein, assuming the number of times the STA has been actively polled within the current CAP is L, the first parameter is -L;

[0078] Determine the number of times the AP has allocated the HCCA TXOP to the STA after receiving the historical request from the STA to obtain the HCCA TXOP, and generate a second parameter and a third parameter;

[0079] Wherein, assuming the number of times the AP has allocated a sufficient amount of the HCCA TXOP to the STA is M, the second parameter is -2*M;

[0080] Assuming the number of times the AP has not allocated a sufficient amount of the HCCA TXOP to the STA is N, the third parameter is -N;

[0081] In an actual application scenario, after the AP receives the request from the STA to obtain the HCCA TXOP, it will allocate a certain length of HCCA TXOP to the STA. However, the length of the HCCA TXOP actually allocated by the AP to the STA is not necessarily equal to the length actually requested by the STA; therefore, when the number of times the length of the HCCA TXOP actually allocated by the AP to the STA is equal to the length actually requested by the STA increases by 1, the value of M is updated to M + 1; then the second parameter is updated to -2*(M + 1); when the number of times the length of the HCCA TXOP actually allocated by the AP to the STA is less than the length actually requested by the STA increases by 1, the value of N is updated to N + 1, and then the third parameter is updated to -(N + 1).

[0082] Determine the number of times the AP has not allocated the HCCA TXOP to the STA after receiving the historical request from the STA to obtain the HCCA TXOP, and generate a fourth parameter.

[0083] Wherein, assuming the number of times the AP has not allocated the HCCA TXOP to the STA is P, the fourth parameter is +P.

[0084] Specifically, the generating a scoring parameter based on the request further includes:

[0085] Determine the length of the allocable HCCA TXOP of the AP within the current CAP, and compare the length of the allocable HCCA TXOP with a second preset threshold; if the length of the allocable HCCA TXOP is greater than or equal to the second preset threshold, generate a fifth parameter;

[0086] Among them, the second preset threshold is the length of the HCCA TXOP requested by the STA.

[0087] Preset x, then the fifth parameter is +x; the value of x can be preset or adjusted according to the length of the allocable HCCA TXOP within the current CAP. If the length of the allocable HCCA TXOP is less than the second preset threshold, generate a sixth parameter.

[0088] Among them, preset y, then the sixth parameter is -y; the value of y can be preset or adjusted according to the length of the allocable HCCA TXOP.

[0089] Specifically, generating the scoring parameter based on the request further includes:

[0090] Based on the received QoS frame, determine whether the effective time of the life cycle of the data frame reported by the STA exceeds a third preset threshold;

[0091] If the STA reports that the effective time of the life cycle of the data frame is greater than or equal to the third preset threshold, generate a seventh parameter.

[0092] Among them, preset z, and the value of the seventh parameter is +z; the AP can preset or adjust the value of z.

[0093] The third preset threshold is the trigger condition for the STA to report that the data frame needs to be sent urgently. Specifically, the third preset threshold is the effective time of the life cycle of the data frame when the STA reports that the data frame needs to be sent urgently.

[0094] In an actual application scenario, the third preset threshold can be 1 / 2 or 1 / 3, etc. of the life cycle of the data frame.

[0095] Step S13: Evaluate the HCCA TXOP permission of the STA based on the scoring parameter to obtain an evaluation result;

[0096] Among them, the initial value or default value of the scoring result is 0, and each time the CAP restarts, the scoring result needs to be statistically recalculated.

[0097] In an actual application scenario, the scoring result can be obtained based on Table 1 below:

[0098] Table 1

[0099]

[0100]

[0101] That is, the scoring result = -L - 2*M - N + P + x - y + z.

[0102] Step S14: Compare the evaluation result with a first preset threshold;

[0103] Step S15: If the evaluation result is greater than or equal to the first preset threshold, allocate the HCCA TXOP to the STA.

[0104] Among them, the first preset threshold is a preset evaluation result, and the value of the first preset threshold can be preset or adjusted according to actual needs.

[0105] Specifically, the step of allocating the HCCA TXOP to the STA if the evaluation result is greater than or equal to the first preset threshold further includes:

[0106] If the evaluation result is greater than or equal to the first preset threshold, obtain the remaining time of the current CAP;

[0107] Compare the remaining time with a fourth preset threshold to obtain a comparison result;

[0108] Based on the comparison result, determine the target length of the HCCA TXOP allocated to the STA.

[0109] Specifically, since the CAP cannot span two TBTT intervals, the maximum remaining time of the CAP refers to the time before the next TBTT arrives; therefore, when the next Beacon is sent, the current CAP is about to end. Of course, the AP can also end the CAP earlier by itself, but this will result in a shorter remaining time of the CAP.

[0110] Among them, the fourth preset threshold is the remaining time of the CAP when the next Beacon is sent.

[0111] By default: If the AP still needs to allocate HCCA TXOP to the STAs within the BSS, then the CAP will try to use the longest time (that is, before the next TBTT).

[0112] In actual application scenarios, determine the value of the fourth preset threshold according to actual needs;

[0113] When the remaining time is greater than or equal to the fourth preset threshold, the AP allocates a full length of the HCCA TXOP to the STA; when the remaining time is less than the fourth preset threshold, the AP allocates a certain length of the HCCA TXOP to the STA according to the remaining time of the current CAP.

[0114] If the evaluation result is less than the first preset threshold, the AP does not allocate the HCCA TXOP to the STA.

[0115] An embodiment of the present invention provides a scoring system for the HC in the AP. For the STA that has submitted an application for the HCCA TXOP, this system can be used to provide an evaluation result, and then decide whether to allocate the HCCA TXOP to the STA and how much HCCA TXOP to allocate; and the scoring system integrates multiple dimensions, making the evaluation result more reasonable; the involved dimensions mainly include two major aspects: the resources of the HC in the AP and the resources of the STA; among them, the resources of the HC in the AP include the remaining available length of the HCCA TXOP and the HCCA TXOP resources that have been actively polled / allocated to the STA; the resources of the STA include the life cycle of the data packets queued by itself, and this life cycle is closely related to the storage capacity of the STA itself and the packet inventory time; when the remaining life cycle of the data packet is short, it can be considered that the AP should allocate resources to this STA as soon as possible to reduce the probability of data packet loss.

[0116] As Figure 2 shown, an embodiment of the present invention also provides a method for scheduling transmission opportunities, which is applied to the STA and includes:

[0117] Step S21: Send a request to the AP to obtain the HCCA TXOP.

[0118] Step S22: Receive the HCCA TXOP allocated by the AP.

[0119] Step S23: Monitor the effective time of the life cycle of the data to be sent.

[0120] Specifically, the monitoring of the effective time of the life cycle of the data to be sent further includes:

[0121] Monitor the effective time of the life cycle of the data to be sent and obtain the effective time.

[0122] Compare the effective time with the third preset threshold.

[0123] If the effective time is greater than or equal to the third preset threshold, adjust the data of the QoS frame to obtain an adjusted QoS frame.

[0124] Send the adjusted QoS frame to the AP.

[0125] Step S24: When the effective time is less than the third preset threshold, send a QoS frame to the AP.

[0126] Specifically, the QoS frame carries information on the TXOP duration request.

[0127] The third preset threshold can be 1 / 2 or 1 / 3, etc.

[0128] In an actual application scenario, if the STA still has data to be sent when the HCCA TXOP allocated by the current AP is about to end, then it will not be able to send this data within a certain period in the future, unless the AP re - allocates a new HCCA TXOP for it; however, since the AP has a very high requirement for the access priority of the channel when allocating HCCA TXOP, when the AP is still allocating HCCA TXOP within the current CAP, the STA cannot compete for the channel, thus causing the data to be sent to be delayed.

[0129] Therefore, in the embodiment of the present invention, when the STA still has data to be sent when the HCCA TXOP allocated by the current AP is about to end, the STA needs to send a QoS frame carrying TXOP Duration Requested to the AP, and the QoS frame carries the TXOP duration information it requests.

[0130] In addition, if any of the data to be sent in the current data to be sent has been waiting in the queue for more than 1 / 2 or 2 / 3, etc. of the life cycle of the data to be sent, then the STA needs to set Bit7 in the QoS Control field of the QoS frame carrying TXOP Duration Requested to 1 and send an adjusted QoS frame to the AP to report to the AP that the data to be sent is in urgent need of being sent.

[0131] In the embodiment of the present invention, the allocation process of HCCA TXOP is a process of resource integration and allocation. Therefore, in this process, considering the resource situations of both the HC in the AP and the STA is a very appropriate approach; in traditional resource allocation strategies, usually only the AP side considers its own resource situation without the information reported by the STA. The embodiment of the present invention adds a link for the STA to report information, which is more conducive to the AP side to measure the resource allocation strategy.

[0132] As Figure 3 shown, the embodiment of the present invention further provides a device 300 for scheduling transmission opportunities, which is applied to the AP and includes:

[0140] Determining the number M of times the AP has allocated the HCCA TXOP to the STA after receiving a historical request for obtaining the HCCA TXOP sent by the STA, and generating a second parameter;

[0141] Determining the number N of times the AP has not allocated the HCCA TXOP to the STA after receiving a historical request for obtaining the HCCA TXOP sent by the STA, and generating a third parameter.

[0142] Optionally, the generating the scoring parameter based on the request further includes:

[0143] Determining the length of the allocable HCCA TXOP within the current CAP, and comparing the length of the allocable HCCA TXOP with a second preset threshold;

[0144] If the length of the allocable HCCA TXOP is greater than or equal to the second preset threshold, generating a fourth parameter;

[0145] If the length of the allocable HCCA TXOP is less than the second preset threshold, generating a fifth parameter.

[0146] Optionally, the generating the scoring parameter based on the request further includes:

[0147] Based on the received QOS frame, determining whether the effective time of the reported data frame life cycle of the STA exceeds a third preset threshold;

[0148] If the STA reports that the valid time of the life cycle of the data frame is greater than or equal to the third preset threshold, a sixth parameter is generated.

[0149] Optionally, the step of allocating the HCCA TXOP to the STA if the evaluation result is greater than or equal to the first preset threshold further includes:

[0150] If the evaluation result is greater than or equal to the first preset threshold, obtain the remaining time of the current CAP;

[0151] Compare the remaining time with a fourth preset threshold to obtain a comparison result;

[0152] Based on the comparison result, determine the target length of the HCCA TXOP allocated to the STA.

[0153] As Figure 4 shown, an embodiment of the present invention further provides a device 400 for scheduling transmission opportunities, which is applied to the STA and includes:

[0154] A request module 401, configured to send a request for obtaining an HCCA TXOP to the AP;

[0155] An obtaining module 402, configured to receive the HCCA TXOP allocated by the AP;

[0156] A monitoring module 403, configured to monitor the valid time of the life cycle of the data to be sent;

[0157] A sending module 404, configured to send a QoS frame to the AP when the valid time is less than the third preset threshold.

[0158] Optionally, the QoS frame carries information about the TXOP duration request.

[0159] Optionally, the step of monitoring the valid time of the life cycle of the data to be sent further includes:

[0160] Monitor the valid time of the life cycle of the data to be sent, and obtain the valid time;

[0161] Compare the valid time with the third preset threshold;

[0162] If the valid time is greater than or equal to the third preset threshold, adjust the data of the QoS frame to obtain an adjusted QoS frame;

[0163] Send the adjusted QoS frame to the AP.
