Background
With the continuous development of wireless local area networks, different service types have different requirements on bandwidth and time delay and different requirements on quality of service (Quality of Service, qoS) due to different service types in the network. An enhanced distributed channel access mechanism (Enhanced Distributed Channel Access, EDCA) is defined in the 802.11e protocol that facilitates the right and more bandwidth for prioritized transmission of high priority traffic data. Wireless communication devices typically support traffic of several traffic types, with traffic of different traffic types corresponding to different transmit queues. When the signal access process is actively initiated, the multiple transmit queues perform channel contention. The transmission queue with successful competition can acquire the channel use opportunity, so as to transmit the service data.
When multiple transmit queues compete for channels, each transmit queue is configured with a fixed priority parameter to enable multiple different services to have different priorities. However, when the network load is large, configuring the fixed priority parameter may cause the high-priority transmission queues to compete for most of the bandwidth, which has a problem that bandwidth allocation to the plurality of transmission queues is not flexible and accurate.

Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.
An embodiment of the application aims to provide a channel competition method, a device, communication equipment and a storage medium, which are used for solving the problem that bandwidth allocation of a plurality of transmission queues is not flexible and accurate in the prior art.
The technology can be realized by adopting corresponding software, hardware and a combination of the software and the hardware. Embodiments of the present application are described in detail below.
Referring to fig. 1, fig. 1 is a flowchart of a channel contention method according to an embodiment of the present application, where the data transmission method may include the following:
step 101: and acquiring the current bandwidth parameter of the queue to be transmitted.
Step 102: and when the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent meet the adjustment conditions, adjusting the time slot parameter of the queue to be sent.
Step 103: and determining the priority parameter of the queue to be sent according to the adjusted time slot parameter so that the queue to be sent performs channel competition according to the priority parameter.
In the embodiment of the application, a current bandwidth parameter of a queue to be sent is firstly obtained, wherein the current bandwidth parameter is the data volume sent by the queue to be sent in a preset time period. And then determining whether the queue to be sent meets the adjustment condition according to the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent. And when the queue to be transmitted meets the adjustment condition, adjusting the time slot parameter of the queue to be transmitted. After the adjusted time slot parameters are determined, the priority parameters of the queues to be sent are determined according to the adjusted time slot parameters, so that the priority parameters of the queues to be sent are adjusted. By the method, the priority parameters of the queue to be sent can be dynamically adjusted, and the queue to be sent can conduct channel competition according to the adjusted priority parameters, so that the capacity of the queue to be sent in the channel competition is changed, and the sending bandwidth of the queue to be sent is adjusted.
In addition, because the time slot parameter can be generated by a clock signal in the network equipment, the precision can reach microsecond or nanosecond level, thereby realizing the high-precision adjustment of the priority parameter of the queue to be sent, and further realizing the high-precision adjustment of the bandwidth of the sending queue.
The above steps are described in detail below.
Step 101: and acquiring the current bandwidth parameter of the queue to be transmitted.
In the embodiment of the application, the current bandwidth parameter of the queue to be sent is the data volume sent by the queue to be sent in a preset time period. And in a preset time period, recording the data quantity transmitted by the queue to be transmitted as the current bandwidth parameter of the queue to be transmitted.
The preset time period can be flexibly set according to the actual network environment. For example, the preset time period may be 1 minute, 10 minutes, 1 hour, or the like. If the load of the current network environment is large, in order to timely adjust the channel competitiveness of the queue to be sent, the preset time period may be set to be shorter, for example, 1 minute, 5 minutes, etc.; if the load of the current network environment is small, the channel competition capability of the queue to be sent does not need to be frequently adjusted, the power consumption of the system is reduced, and the preset time period can be set longer, for example, 1 hour, 2 hours, 1 day and the like.
Step 102: and when the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent meet the adjustment conditions, adjusting the time slot parameter of the queue to be sent.
In the embodiment of the application, after the current bandwidth parameter of the queue to be sent is obtained, whether the queue to be sent meets the adjustment condition is judged according to the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent. The target bandwidth parameter of the queue to be sent is a bandwidth parameter preset according to the priority of the queue to be sent. The target bandwidth parameter of the queue to be transmitted characterizes the amount of data expected to be transmitted by the queue to be transmitted in a preset time period.
The queue to be transmitted is a queue in the network environment in which data is to be transmitted. Different service types exist in the network, and different service types have differences in requirements on bandwidth and time delay, so that the target bandwidth parameters of different transmission queues have differences.
For example, in the EDCA mechanism of the 802.11e protocol, 4 different Access Categories (ACs) are defined according to different traffic data flows, and the priority is respectively as follows: ac_vo (Voice), ac_vi (Video), ac_be (Best Effort), and ac_bk (Background). One for each access class. The system expects that the transmission queue with high priority occupies more bandwidth and preferentially transmits service data. Thus, the higher the priority, the higher the target bandwidth parameter corresponding to the transmit queue.
The following describes the adjustment conditions.
When the queue to be transmitted meets the adjustment condition, the fact that the data volume actually transmitted by the queue to be transmitted is larger than the data volume expected to be transmitted in a preset time period is shown; otherwise, when the queue to be sent does not meet the adjustment condition, the data quantity actually sent by the queue to be sent is smaller than the data quantity expected to be sent in a preset time period.
As an optional implementation manner, if the difference value between the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent is not in the preset threshold range, it is determined that the queue to be sent meets the adjustment condition.
In the embodiment of the application, a preset threshold range is set, if the difference value between the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent is not in the preset threshold range, the fact that the actual data volume sent by the queue to be sent and the expected data volume have larger difference value within a preset time period is represented, the adjustment condition is met, and the time slot parameter of the queue to be sent needs to be adjusted.
For example, the preset threshold may range from-10 kb to 10kb, with a preset time period of 1 second. If the data volume sent by the queue to be sent in 1 second is 100kb, the target bandwidth parameter corresponding to the queue to be sent is 120kb, the difference value between the target bandwidth parameter and the target bandwidth parameter is-20 kb, and the difference value is not in the preset threshold value range, the fact that the actual data volume sent by the queue to be sent and the expected data volume have larger difference in the preset time period is indicated, the adjustment condition is met, and the time slot parameter of the queue to be sent needs to be adjusted. If the data volume sent by the queue to be sent in 1 second is 125kb, the target bandwidth parameter corresponding to the queue to be sent is 120kb, and the difference value between the two is 5kb, in the preset threshold range, the fact that the actual data volume sent by the queue to be sent and the expected data volume have smaller difference in the preset time period is indicated, the adjustment condition is not met, and the time slot parameter of the queue to be sent is not required to be adjusted.
As another alternative embodiment, if the ratio of the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent is not in the preset threshold range, it is determined that the queue to be sent meets the adjustment condition.
In the embodiment of the application, a preset threshold range is set, if the ratio of the current bandwidth parameter of the queue to be sent to the target bandwidth parameter of the queue to be sent is not in the preset threshold range, the fact that the actual data volume sent by the queue to be sent and the expected data volume have larger difference in a preset time period is represented, the adjustment condition is met, and the time slot parameter of the queue to be sent needs to be adjusted.
For example, the preset threshold may range from 0.5 to 1.5, with a preset time period of 1 second. If the data volume sent by the queue to be sent in 1 second is 200kb, the target bandwidth parameter corresponding to the queue to be sent is 100kb, the ratio of the two is 2kb, and the data volume is not in the preset threshold range, the fact that the actual data volume sent by the queue to be sent and the expected data volume have large difference in the preset time period is indicated, the adjustment condition is met, and the time slot parameter of the queue to be sent needs to be adjusted. If the data volume sent by the queue to be sent in 1 second is 80kb, the target bandwidth parameter corresponding to the queue to be sent is 100kb, the ratio of the two is 0.8, and in the preset threshold range, the fact that the actual data volume sent by the queue to be sent and the expected data volume have smaller phase difference in the preset time period is indicated, the adjustment condition is not met, and the time slot parameter of the queue to be sent is not required to be adjusted.
It should be noted that, the adjusting conditions in the embodiment of the present application are not limited in particular, and the conditions that can determine whether the data amount actually transmitted by the queue to be transmitted and the data amount expected to be transmitted differ greatly can be both used as the adjusting conditions.
To facilitate understanding of the scheme, the manner of channel contention and slot parameters are described below.
In order to meet the QoS requirements of the transmission queues with different priorities, each transmission queue corresponds to one priority parameter, and the transmission queues perform transmission channel competition according to the priority parameter corresponding to the transmission queues. The priority parameters may include: the interframe space (Arbitration Inter Frame Space, AIFS) and the BACKOFF parameter (BACKOFF) are arbitrated.
The AIFS of a transmit queue determines the arbitration contention slot period of the transmit queue. The arbitration inter-frame space AIFS can be expressed as: aifs=sifs+aifsn [ AC ]. Slat. Wherein SIFS is Short Inter-Frame Space (Short Inter-Frame Space), and SLOT is a SLOT parameter.
The backoff parameter of a transmit queue determines the backoff slot period of the transmit queue. The BACKOFF parameter BACKOFF may be expressed as: back off=cw_sel. Wherein SLOT is a SLOT parameter.
When a certain transmission queue has data transmission requirement, the transmission queue detects the channel, and when the channel is in an idle state in a period of time corresponding to the transmission queue AIFS [ AC ], a back-off flow is started. In the back-off process, if the channel is still in an idle state, the BACKOFF corresponding to the transmission queue is continuously reduced, and when the BACKOFF is reduced to 0, the transmission queue obtains the channel use right, and the system transmits the service data corresponding to the transmission queue on the channel.
In the embodiment of the application, the time SLOT parameter is SLOT in the arbitration inter-frame space AIFS and the BACKOFF parameter BACKFF.
As an alternative embodiment, the slot parameters are used to determine arbitration inter-frame spacing and backoff parameters.
In an embodiment of the present application, the arbitration inter-frame space AIFS may be expressed as: aifs=sifs+aifsn [ AC ]. SLOT, the BACKOFF parameter BACKOFF may be expressed as: back off=cw_sel. Wherein SLOT is a SLOT parameter.
As another alternative embodiment, the slot parameters of the queue to be transmitted include a first slot parameter and a second slot parameter. The first slot parameter is used to determine the arbitration inter-frame space and the second slot parameter is used to determine the backoff parameter.
In an embodiment of the present application, the arbitration inter-frame space AIFS may be expressed as: aifs=sifs+aifsn [ AC ]. SLOT1, SLOT1 being the first SLOT parameter. The BACKOFF parameter BACKOFF may be expressed as: back off=cw_sel×slot2, SLOT2 being the second SLOT parameter.
When the time slot parameter is adjusted, only the first time slot parameter, only the second time slot parameter or both the first time slot parameter and the second time slot parameter can be selected according to actual conditions.
And adjusting the priority parameter of the queue to be transmitted by adjusting the time slot parameter, and performing channel competition by the queue to be transmitted according to the adjusted priority parameter. When the current bandwidth parameter of the queue to be sent is smaller, the time slot parameter of the queue to be sent is reduced, and when the queue to be sent performs channel competition, the channel can be more quickly contended, so that data transmission is realized, and the current bandwidth parameter of the queue to be sent is improved; when the current bandwidth parameter of the queue to be sent is larger, the time slot parameter of the queue to be sent is improved, and when the queue to be sent performs channel competition, the channel use right cannot be obtained rapidly, so that the current bandwidth parameter of the queue to be sent is reduced.
The following describes a way to adjust the slot parameters of the queues to be transmitted.
In the embodiment of the application, when the queue to be sent meets the adjustment condition, the time slot parameters of the queue to be sent are adjusted according to the following principle:
when the current bandwidth parameter of the queue to be sent is larger than the target bandwidth parameter of the queue to be sent, the larger the current bandwidth parameter of the queue to be sent is, the larger the adjusted time slot parameter is;
when the current bandwidth parameter of the queue to be sent is smaller than the target bandwidth parameter of the queue to be sent, the smaller the current bandwidth parameter of the queue to be sent is, the smaller the adjusted time slot parameter is.
According to the channel contention mode, if the current bandwidth parameter of the queue to be sent is greater than the target bandwidth parameter of the queue to be sent, it is indicated that the queue to be sent occupies more channel resources. The time slot parameters of the queue to be sent are increased, so that the data volume sent by the queue to be sent can be effectively reduced.
If the current bandwidth parameter of the queue to be sent is smaller than the target bandwidth parameter of the queue to be sent, the queue to be sent is indicated to occupy less channel resources. The time slot parameters of the queue to be sent are reduced, so that the data volume sent by the queue to be sent can be effectively improved.
As an alternative embodiment, adjusting the timeslot parameters of the queue to be sent includes: determining an adjustment amplitude according to the numerical relation between the current bandwidth parameter of the queue to be transmitted and the target bandwidth parameter of the queue to be transmitted; and adjusting the time slot parameters of the queue to be transmitted according to the adjustment amplitude.
In the embodiment of the application, after the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent are obtained, the adjustment amplitude of the time slot parameter is determined by comparing the numerical relation of the current bandwidth parameter and the target bandwidth parameter of the queue to be sent, and then the time slot parameter of the queue to be sent is adjusted according to the adjustment amplitude.
Specifically, the adjustment amplitude is a, and the time SLOT parameter of the queue to be sent is SLOT. After the adjustment amplitude a is determined, the SLOT parameter of the queue to be sent is adjusted to a SLOT.
In some embodiments, determining the adjustment amplitude according to a numerical relationship between a current bandwidth parameter of the queue to be transmitted and a target bandwidth parameter of the queue to be transmitted includes:
the adjustment amplitude is determined according to the following formula:
wherein y is the adjustment amplitude, x is the ratio of the first parameter to the target bandwidth parameter of the queue to be sent, and the first parameter is the difference between the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent.
For example, the current bandwidth parameter of the queue to be sent is 80kb, the target bandwidth parameter of the queue to be sent is 100kb, the difference between the current bandwidth parameter of the queue to be sent and the target bandwidth parameter of the queue to be sent is 20kb, the first parameter is 20kb/100 kb=0.2, and x=0.2. As can be seen from the above formula, the adjustment amplitude y is 0.83.
In other embodiments, determining the adjustment amplitude according to a numerical relationship between a current bandwidth parameter of the queue to be transmitted and a target bandwidth parameter of the queue to be transmitted includes: and determining the adjustment amplitude according to the numerical relation and a preset adjustment strategy.
In the embodiment of the application, an adjustment strategy is pre-configured, and the adjustment strategy is used for representing the corresponding relation between the numerical relation and the adjustment amplitude.
