Interrupt level.Such as in typical case, video and audio content is to very sensitive to postponing, it means that they cannot allow to prolong
Late, thus, grouping and frame delay transmission unacceptable service quality (quality of can be generated to communication service
Service, QoS) grade, when network load aggravates, this problem is especially serious.

Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, those skilled in the art's every other implementation obtained without making creative work
Example, shall fall in the protection scope of this application.
The embodiment of the present application can be applied to WLAN (wireless local area networks, WLAN),
WLAN accepted standard is IEEE802.11 series at present.WLAN may include multiple basic service sets (basic service
Set, BSS), in BSS, all STA are associated on an AP, which controls and dominate the biography of the total data in entire BSS
STA in defeated process, that is, all wireless networks is obtained to communication and is passed through AP.It is exactly as shown in Figure 1 a BSS, including
One AP and three STA (STA1, STA2 and STA3).
AP is the access point of a wireless network, is commonly called as " hot spot ".Mainly there is route switching access integrated equipment and pure connects
Enter point device, integrated equipment executes access and routing work, and pure access device is only responsible for the access of wireless client, and pure access is set
Standby extend usually as wireless network uses, and connect with other AP or main AP, to expand wireless coverage, and integrated equipment
The usually core of wireless network.
STA indicates that the equipment being connected in wireless network, these equipment, can be with internal other equipment or nothings by AP
Gauze network PERCOM peripheral communication, STA are generally client in a wlan, can be the computer equipped with wireless network card, be also possible to have
The smart phone of WiFi module, STA can be mobile, are also possible to fixed, are the basic component units of WLAN.
Fig. 2A is please referred to, is a kind of embodiment schematic diagram of possible wireless communications method provided by the embodiments of the present application,
This method can include:
201, AP confirms that target STA has time justice sexuality；
In practical application, 2.4G frequency range WiFi used in us, what is abided by is 802.11n standard, it allows STA simultaneously
Using mutiple antennas while receiving and transmitting signal, to achieve the purpose that bandwidth is double.But, although 802.11n can highest support arrive
800Mbps bandwidth, but same time AP can only be communicated with a STA, i.e., and when multiple STA access the same AP, they are needed
It is successively lined up and is serviced.However, due in actual conditions, the wireless connection bandwidth between AP and STA will receive STA hardware,
Various influences such as signal strength, interference level will generate not when there is STA at a slow speed in entire WLAN
Fairness.For example, STA1 and STA2 accesses an AP simultaneously, the connection speed of STA1 is 1Mbps, and the connection speed of STA2 is
5Mbps, when STA1 needs to transmit 1OM data, STA2 must not be not to wait for starting within 10 seconds to transmit, and cause high-performance and set
The unfairness of standby STA2, also causes the transmission performance of entire WLAN to reduce.
In view of this, in the application, for ease of description, the WLAN is added in the WLAN that AP is set up
All STA be known as STA groups, any STA in the STA crowds is known as target STA.AP judges whether target STA has time public affairs
Levelling ability, it is to be understood that in practical application, AP confirmation target STA has there are many modes of time justice sexuality,
For example, when AP is connect with target STA first message can be sent to target STA, which is used to indicate target STA
It reports and whether supports time justice sexuality, after receiving the first message, target STA sends first message response to AP, therefore
By the first message response confirmation, whether it has time justice sexuality to AP.Alternatively, in AP and target STA connection procedure
In, AP receives the frame that target STA is sent, and in the frame includes whether the instruction target STA has time justice sexuality
Information, wherein the frame can be allow send (clear to send, CTS) frame or request send (request to send,
RTS) frame, therefore whether AP can have time justice sexuality by the frame acknowledgment target STA that target STA is sent.In addition,
When the time that AP confirmation target STA has time justice sexuality can establish connection for AP and target STA, or AP
When transmitting data packet with target STA, target STA can also be actively triggered by AP and sends instruction information or by target STA active
It reports, therefore AP confirmation target STA has the mode of time justice sexuality specifically herein without limitation.
In addition, STA can be the dress appropriate for being connected to distributed network by Radio Link in the embodiment of the present application
It sets.For example, STA can be mobile computer, personal digital assistant, Internet of Things (internet to things, IoT) equipment
(such as smartwatch, Intelligent bracelet), portable device (such as cellular GPRS phones), ultra wide band (ultra wide band,
UWB) device or wireless device etc., specifically herein without limitation.
It should be noted that AP may also include, be implemented or referred to as radio network controller (RNC), B node,
Evolved B node, base station controller, base station transceiver machine, base station, transceiver function, Radio Router, wireless set
Or some other term, specifically herein without limitation.
Optionally, the embodiment of the present application is also not necessarily limited to GPRS and wlan network, can also be station and central controller (i.e.
The base station in AP and GPRS in WLAN) with the network of different physical transmission rate communication, specifically herein without limitation.
202, AP confirms the transmittability of each STA in STA crowds；
In the WLAN that AP is set up, the transmittability of each STA is different in STA groups, therefore in order to solve time justice
Property problem, AP need to confirm the transmittability of each STA in STA crowds.In practical application, AP confirms that the mode of each STA transmittability has
It is a variety of, such as: AP determines the transmission range of each STA to AP, it is to be understood that the distance of signal transmission is longer, is subject to
Noise jamming and decaying are also bigger, therefore its signal strength can also successively decrease, thus the transmittability of STA is also weaker.Therefore AP can lead to
It crosses each STA and is sent to it the signal strength of networking request message to judge the distance of each STA to AP, for example, transmitted by STA3
The signal strength of networking request message is less than the signal strength for the networking request message that STA4 is sent, therefore AP can consider STA3
It is greater than the distance of STA4 to AP to the distance of AP, the transmittability of corresponding STA3 is less than the transmittability of STA4.In addition,
There are many modes of physics spacing between AP determination and each STA, other than being judged according to the signal strength of networking request message,
It can also be according to the frequency of signal.Since the frequency of signal is bigger, transmission range is shorter, therefore AP can pass through different frequency
Signal sends message to each STA, for example, can receive the response of STA5 when AP sends message with a certain frequency, not receive but
The response of STA6, it may be considered that the distance of STA5 distance AP is less than the distance of STA6 distance AP, the transmission of corresponding STA5
Ability is greater than the transmittability of STA6, therefore AP can determine the distance of each STA by the difference of signal frequency, and then confirm
The transmittability of a STA.
Optionally, AP can also determine the transmission rate of each STA in STA crowds, and determine each STA's according to the transmission rate
Transmittability, it is to be understood that the transmission rate of STA is bigger, and the transmittability of corresponding STA is also stronger.For example, actually answering
In, AP can send identical request to each STA simultaneously, and indicate that each STA replys response, it is believed that AP was received
Response is faster, also closer to the distance for the STA that should respond to, therefore the transmittability of STA is also stronger.To sum up, AP confirms STA groups
In each STA transmittability the specific the application of mode without limitation.
It should be noted that AP confirms that target STA has time justice performance by step 201 in the embodiment of the present application
Power confirms the transmittability of each STA in STA crowds by step 202, and between the two processes and the successive suitable of step is not present
Sequence can first carry out step 201, can also first carry out step 202, or be performed simultaneously, specifically herein without limitation.
Optionally, if AP first carries out step 201, then step 202 is executed, there may be target STA not to have in practical application
The scene of having time justice sexuality, thus can be set do not have the STA of time justice sexuality transmittability be less than have
The transmittability of the STA of time justice sexuality, specifically herein without limitation.
203, AP determines the transmission opportunity priority of each STA according to the transmittability of STA each in STA crowds；
In AP confirmation STA groups after the transmittability of each STA, determine each STA's according to the transmittability of STA each in STA crowds
Transmission opportunity priority, it is to be understood that the higher STA of transmittability, corresponding transmission opportunity priority is higher, that is, exists
It, can be by the higher STA prioritised transmission data packet of transmission opportunity priority when transmitting some data packet.For example, it is assumed that STA groups
In include { STA1, STA2, STA3 }, AP confirms that each STA in STA crowds is provided with time justice sexuality, and transmittability is
STA1 > STA3 > STA2, therefore it can be STA1 > STA3 > STA2 that AP determining transmission opportunity priority is corresponding.
204, AP configuration instruction information in scrambler sequence；
It should be noted that in digital communication, if often there is 0 or 1 long sequence, it will influence the foundation of bit synchronization
And holding, in transmitters use scrambling code, can to avoid this data to the adverse effect of receiver timing, meanwhile, in order to limit
Different degrees of nonlinear characteristic crosstalk caused by other circuit communications present in circuit processed, it is desirable that the minimum of digital signal
Period long enough can meet the requirements digital signal conversion at the Serial No. for being similar to white noise statistical property, this
It is usually realized with scrambling, so-called scrambling, is exactly increased without redundancy and jammer signal, change digital signal statistical property, makes
It has a kind of technology of approximate white noise statistical property, therefore in the wireless network of 802.11 standards, AP is sent to STA
Arbitrary frame in all include scrambler sequence, the total 7bit of the scrambler sequence.
After AP has determined the transmission opportunity priority of each STA according to the transmittability of STA each in STA crowds, in scrambler sequence
Middle configuration instruction information, the instruction information are used to indicate the transmission opportunity priority of target STA in the wireless network, wherein such as
It is a kind of schematic diagram of possible scrambler sequence provided by the embodiments of the present application shown in Fig. 2 C, includes 7 in the scrambler sequence
Bits, bit1~bit7, AP can carry instruction information by bit1 and bit2, in practical application, can choose this 7
The bits of arbitrary continuation position carries the instruction information in bits, specifically herein without limitation.For example, the bit1 of the scrambler sequence
Target STA is used to indicate with bit2 and needs opening time fairness, and bit3~bit5 is for informing target STA in wireless local area
Transmission opportunity priority in net, it is to be understood that meaning represented by the combined value of different bits or multiple bits
It may include in preset table, and the preset table is AP and STA groups shared in advance.
It should be noted that the first instruction of configuration information will not influence the original upset of scrambler sequence in scrambler sequence
Effect.
205, AP sends the frame comprising scrambler sequence to target STA；
After AP configures the instruction information in scrambler sequence, the frame comprising the scrambler sequence is sent to target STA.Wherein,
The frame can be CTS frame, RTS frame, control frame or data frame etc., specifically herein without limitation.
Optionally, AP meeting fixed time broadcast sends beacon frame, is mainly used to notify the presence of network AP, each in STA groups
STA can be obtained by scanning Beacon, furthermore further include a bitmap file in beacon frame to learn the presence of AP
(bitmap), STA can know whether itself received data in need from bitmap, and as shown in Figure 2 B, which is
Totally 9 positions, different STA have unique corresponding position therewith to the matrix structure of one three row three column, and there are 0 and 1 two kind in each position
It indicates, 1 indicates data buffer storage, and 0 indicates that no data caches, it can thus be seen that STA1 and STA2 is in need, itself is received
Data, STA3 do not need itself received data.
It should be noted that the bitmap in beacon frame can only inform that target STA there are data to need its reception, and transmit
Chance priority STA can only be known by the instruction information that AP is configured in scrambler sequence, and in the present embodiment, AP can believe instruction
Cease the scrambler sequence being added in beacon frame.
206, target STA is carried out wireless communication according to frame and AP.
After target STA receives the frame comprising scrambler sequence, operation is decoded to obtain in the scrambler sequence to the frame
Instruction information, and obtain the transmission opportunity priority that indicates in instruction information, carried out wireless communication with AP, including control plane
Signaling and/or the data packet in user face.
It should be noted that in the embodiment of the present application, AP configuration instruction in scrambler sequence in step 204 to step 206
Information simultaneously sends the frame comprising the scrambler sequence to target STA, is illustrated by taking a STA as an example, AP in the present embodiment
Step 204 is executed with each of STA crowds STA to step 206, so that AP is each of WLAN
STA configures the scrambler sequence comprising instruction information.
In the embodiment of the present application, AP is by the configuration instruction information in scrambler sequence, to inform mesh in active wireless network
The transmission opportunity priority of STA is marked, therefore AP can work as in wireless network by defining the transmission opportunity priority of each STA
