It can also be applied to the AP or AC of other network environments, the present embodiment is simultaneously not limited.It should be understood that the present embodiment
In illustrated with a kind of networking model therein, but should not be with this as limitation.As shown in Figure 1, the message transmitting party
Method may comprise steps of：
For ease of description, below using the executive agent of step 101~102 as the networking of AC+Fit AP (hereinafter referred to as AP)
It is illustrated for AC in environment.
Step 101, the quality of eating dishes without rice or wine for determining AP.
In the embodiment of the present invention, in order to improve the reasonability of message transmitting spped rate selection, when AC is needed through AP to STA
When (website) sends message, AC can first determine the quality of eating dishes without rice or wine of AP, and so as to the quality of eating dishes without rice or wine according to AP, determine that AP is sent out to STA
Deliver newspaper text message transmitting spped rate.
In the present invention in one embodiment, the quality of eating dishes without rice or wine of above-mentioned determining AP can include：
Receive the mass parameter of eating dishes without rice or wine in the predetermined period that AP is reported；
Mass parameter of eating dishes without rice or wine according to receiving determines that the first quality and second of eating dishes without rice or wine is eated dishes without rice or wine quality respectively, wherein, institute
The first quality of eating dishes without rice or wine is stated to eat dishes without rice or wine more than second quality.
In this embodiment, AP periodically can report mass parameter of eating dishes without rice or wine to AC, wherein, which can
To include but not limited to one or more of following parameter：
Utilization rate (Util), conflict (Conf), packet loss (Per) and interference (Intf).
Wherein, the ratio for the message for needing itself processing that utilization rate is detected for AP in predetermined period；Conflict for AP
What is detected in predetermined period does not need to the ratio of the message of itself processing；Packet loss is sent out for AP in predetermined period to STA
Deliver newspaper text packet loss；Interfere the shadow for non-WLAN (Wireless Local Area Network, WLAN) signal
It rings, the determining associated description that may refer in existing related realization of concrete numerical value.
It in this embodiment, can be according to the matter of eating dishes without rice or wine received after AC receives the mass parameter of eating dishes without rice or wine that AP is reported
Amount parameter determines eat dishes without rice or wine quality of the AP in predetermined period.
For example, AC can determine eat dishes without rice or wine quality Qs of the AP in predetermined period by the following formula：
Q=100%- (Util+Conf/2)-Per/N-2*Intf；
Wherein, N be the client (client, i.e. STA) that the client actual influences that detect lose mark rate in networking etc.
Valence mumber amount.In general, increasing with the quantity of the client in networking, packet loss are not linearly to increase, but are increased
After to a certain extent, tend to gentle.For example, when client quantity is between 20-30, then can be considered as practical to packet loss
The quantity for the client having an impact is 5, and the client for generating packet loss can be equivalent to 5, i.e. equivalent number N at this time
=5；When client be more than 30, equivalent number N=8；When client is between 10-20, equivalent number N=4；When client is less than
10, equivalent number N=2.Specifically, the mapping relations between client and N, can carry out true according to practical test result
It is fixed, and then be pre-configured in AC.It can not also be discussed by theoretical calculation, specific computational methods the present embodiment.
Above-mentioned formula is only to determine a kind of embodiment for quality of eating dishes without rice or wine, certainly, in the mass parameter difference of eating dishes without rice or wine of consideration
When, the formula for the quality that determines to eat dishes without rice or wine can then generate variation accordingly, will not enumerate in the present embodiment.
In this embodiment, in order to improve the reference value for quality of eating dishes without rice or wine, AC can (can root in preset quantity according to AP
Quality of eating dishes without rice or wine in factually border scene settings, such as 3,5) predetermined period determines the quality of eating dishes without rice or wine of AP, and according to the matter of eating dishes without rice or wine
Amount determines that AP sends the transmission rate of message.
For example, can by AP the quality of eating dishes without rice or wine of the predetermined period of the preset quantity arithmetic number average value or weighted average
Value is determined as the quality of eating dishes without rice or wine of AP；Alternatively, AP can be determined in the small value of the quality of eating dishes without rice or wine of the predetermined period of the preset quantity
Quality of eating dishes without rice or wine for AP etc..
Correspondingly, in the present invention in one embodiment, quality that above-mentioned basis received eat dishes without rice or wine determines the respectively
One quality and second of eating dishes without rice or wine is eated dishes without rice or wine quality, can be included：
Determine that first eats dishes without rice or wine quality according to the average value of the quality of eating dishes without rice or wine of predetermined period, according to the quality of eating dishes without rice or wine of predetermined period
Minimum value determine that second eats dishes without rice or wine quality.
As an example it is assumed that nearest 3 periods that AC is determined according to the mass parameter of eating dishes without rice or wine in nearest 3 periods that AP is reported
Quality of eating dishes without rice or wine be respectively Q1, Q2 and Q3, then the first quality of eating dishes without rice or wine that AC is determined can be (Q1+Q2+Q3)/3；Second eats dishes without rice or wine matter
Amount can be MIN (Q1, Q2, Q3), and MIN is the function being minimized.
Step 102, control AP carry out message transmission with the corresponding transmission rate of the quality of eating dishes without rice or wine of AP.
In the embodiment of the present invention, after AC determines the quality of eating dishes without rice or wine of AP, can be determined according to the quality of eating dishes without rice or wine of AP AP into
The transmission rate that row message is sent, and the transmission rate is sent to AP, so that AP carries out message transmission according to the transmission rate.
As it can be seen that in method flow shown in Fig. 1, since according to the characteristics of WLAN, radio frequency is in eat dishes without rice or wine to use one section
Between within, maintain certain trend, and within subsequent certain time, still can maximum probability keep this trend, thus, adopt
Determine that the first quality of eating dishes without rice or wine can preferably predict the quality of eating dishes without rice or wine of follow-up a period of time with average value.According to matter of eating dishes without rice or wine
Amount determines that transmission rate can avoid the waste of interface-free resources while the message transmission probability of success is improved.
Further, in the present invention in one embodiment, above-mentioned control AP is with the corresponding transmission of quality of eating dishes without rice or wine of AP
Rate carries out message transmission, including：
Control AP eats dishes without rice or wine the progress message transmission of quality corresponding first transmission rate using first；
When AP using the first transmission rate send message failure when, control AP using second eat dishes without rice or wine quality it is corresponding second send out
Transmission rate carries out reduction of speed transmission to message.
In this embodiment, it eats dishes without rice or wine when AC defines first respectively according to the mass parameter of eating dishes without rice or wine that the AP received is reported
Quality and second is eated dishes without rice or wine after quality, and AC first can determine corresponding transmission rate (referred to herein as according to the first quality of eating dishes without rice or wine
First transmission rate), for example, AC can be according to mapping relations (the wherein mapping pass of preset eat dishes without rice or wine quality and transmission rate
System can be by counting or determining based on experience value), determine transmission rate corresponding with quality of eating dishes without rice or wine.
After AC determines the first transmission rate, AP can be controlled to carry out message transmission with the first transmission rate, if message
Transmission failure a, for example, message at least occur sends failure, alternatively, the probability of message transmission failure reaches in preset duration
To predetermined threshold value, AC then determines that the first transmission rate is excessively high, at this point, AC can eat dishes without rice or wine according to the second of AP, quality determines another
Less than the transmission rate (i.e. the second transmission rate) of the first transmission rate, and AP is controlled to carry out message hair with the second transmission rate
It send.
Wherein, in embodiments of the present invention, the mapping relations of quality of eating dishes without rice or wine and transmission rate can be quality section of eating dishes without rice or wine
With the mapping relations of transmission rate, a quality section of eating dishes without rice or wine corresponds to a transmission rate, when the lower limit that one eats dishes without rice or wine quality section
More than or equal to another quality section of eating dishes without rice or wine the upper limit when, the corresponding transmission speed in quality section of eating dishes without rice or wine is more than another matter of eating dishes without rice or wine

Correspondingly, in order to avoid the first quality of eating dishes without rice or wine eats dishes without rice or wine with second that (i.e. first sends speed to the corresponding transmission rate of quality
Rate and the second transmission rate) it is identical, when second eat dishes without rice or wine quality with first eat dishes without rice or wine quality belong to it is same eat dishes without rice or wine quality section when, need
It will eat dishes without rice or wine that quality section is adjacent with this and the corresponding transmission rate in the smaller quality section of eating dishes without rice or wine of numerical value is determined as the second transmission speed
Rate, to ensure that the second transmission rate is less than the first transmission rate.
What deserves to be explained is in embodiments of the present invention, due to AP to different types of STA send message when, optionally
Transmission rate is also not exactly the same, and therefore, AC, can also be according to the type of STA when determining that AP sends the transmission rate of message
It determines, i.e. AC can determine that AP sends the transmission rate of message to different types of STA respectively.
Correspondingly, the mapping relations of above-mentioned eat dishes without rice or wine quality and transmission rate can respectively include STA pairs of variant type
The mapping relations of eat dishes without rice or wine quality and transmission rate answered；As AC it needs to be determined that AP sends report to certain STA (being properly termed as target STA)
During the transmission rate of text, it is corresponding can target STA types to be inquired according to the type of target STA and the quality of eating dishes without rice or wine of AP
The mapping relations of quality of eating dishes without rice or wine and transmission rate send the transmission rate of message to determine AP to target STA.
For example, it is assumed that the type of STA includes Class1, type 2 and type 3, then it can preset and preserve quality of eating dishes without rice or wine
With mapping relations 1 (abbreviation mapping relations 1, corresponding with STA Class1), the mapping relations 2 (being corresponded to STA types 2) of transmission rate
And mapping relations 3 (corresponding with STA types 3)；As AC it needs to be determined that AP sends the transmission rate of message to the STA of STA types 2
When, AC can send speed according to the quality inquiry mapping relations 2 of eating dishes without rice or wine of identified AP to determine that the quality of eating dishes without rice or wine is corresponding
Rate, and AP is controlled to send message to the STA of STA types 2 with the transmission rate.
Further, in another embodiment, above-mentioned control AP sends speed so that the quality of eating dishes without rice or wine of AP is corresponding
Rate carries out message transmission, including：
Control AP eats dishes without rice or wine the progress message transmission of quality corresponding first transmission rate using first；
When AP is successfully transmitted the quantity of message with the first transmission rate reaches predetermined threshold value, the first transmission rate is promoted,
And AP is controlled to carry out message transmission with the transmission rate after being promoted；
If AP sends message failure with the transmission rate after being promoted, when transmission rate is reduced to last send successfully
Transmission rate, and control AP with the transmission rate carry out message transmission.
In this embodiment, when AP with the first transmission rate be successfully transmitted message quantity reach predetermined threshold value (can root
Factually border scene settings) when, AC can promote the first transmission rate of AP, and AP is controlled to be reported with the transmission rate after being promoted
Text is sent；If AP is successfully transmitted the quantity of message with the transmission rate after being promoted when reaching above-mentioned predetermined threshold value, AC can be after
It is continuous to carry out speed-raising processing；If AP sends message failure with the transmission rate after being promoted, transmission rate can be reduced to by AC
Transmission rate when once sending successfully, and AP is controlled to carry out message transmission with the transmission rate.
Further, in the present invention in one embodiment, above-mentioned control AP is with the corresponding transmission of quality of eating dishes without rice or wine of AP
After rate carries out message transmission, it can also include：
Timing updates the quality of eating dishes without rice or wine of AP；
According to the updated quality update transmission rates of eating dishes without rice or wine of AP, and AP is controlled to carry out message with updated transmission rate
It sends.
In this embodiment, it is contemplated that the quality of eating dishes without rice or wine of AP not is changeless, and correspondingly, AP is most appropriate for reporting
The message transmitting spped rate that text is sent is also can be changed, and therefore, AC determines transmission rate, and control according to the quality of eating dishes without rice or wine of AP
After AP processed sends message with transmission rate, AC can also periodically update the quality of eating dishes without rice or wine of AP, and according to the updated skies of AP
Mouth quality update transmission rate, and AP is controlled to carry out message transmission with updated transmission rate.
What deserves to be explained is in this embodiment, after the quality of eating dishes without rice or wine of AC updates AP, in addition to can be sent according to first
Except rate, the second transmission rate can also be updated, and when AP sends message failure with updated first transmission rate, control
AP processed carries out message transmission with updated second transmission rate.
In order to which those skilled in the art is made to more fully understand technical solution provided in an embodiment of the present invention, with reference to specific
Application scenarios illustrate technical solution provided in an embodiment of the present invention.
As shown in Fig. 2, for a kind of configuration diagram of concrete application scene provided in an embodiment of the present invention, as shown in Fig. 2,
In the application scenarios, AP1 (AP2) reports quality report of eating dishes without rice or wine using 2s as the period to AC, which includes AP1
(AP2) mass parameter of eating dishes without rice or wine in nearest 2s；AC determines AP1 according to the AP1 (AP2) received the mass parameters of eating dishes without rice or wine reported
(AP2) quality of eating dishes without rice or wine, and determine that AP1 (AP2) sends the message transmitting spped rate of message according to the quality of eating dishes without rice or wine of AP1 (AP2),
It is following (by taking the realization of AP1 as an example, i.e., by above-mentioned AP for for AP1) to implement flow：
1st, AP1 reports quality report of eating dishes without rice or wine every 2s to AC, which includes skies of the AP1 in nearest 2s
Mouth mass parameter；Wherein, the mass parameter of eating dishes without rice or wine is including the use of rate (Util), conflict (Conf), packet loss (Per) and interference
(Intf)；
2nd, AC determines eat dishes without rice or wine quality of the AP1 in signal period according to the mass parameter of eating dishes without rice or wine of AP1 using the following formula：
Q=100%- (Util+Conf/2)-Per/N-2*Intf；
3rd, AC according to (assuming that respectively T1, T2, T3) in AP1 nearest 3 periods quality of eating dishes without rice or wine (assuming that respectively Q1,
Q2, Q3) determine that the first of the AP1 quality Q a and second that eats dishes without rice or wine eats dishes without rice or wine quality Q b respectively：Wherein：
Qa=(Q1+Q2+Q3)/3
Qb=MIN (Q1, Q2, Q3)
Wherein, MIN (Q1, Q2, Q3) is the minimum value taken in Q1, Q2 and Q3；
4th, AC eats dishes without rice or wine quality (i.e. Qa) and the type of target STA according to the first of AP1, the type pair of inquiry target STA
The mapping relations of eat dishes without rice or wine quality and transmission rate answered are eated dishes without rice or wine corresponding first transmission rate of quality with determine AP1 first, and
AP1 is controlled to carry out message transmission with the first transmission rate；
Wherein, in this embodiment, the type of STA can include but is not limited to Leagcy types (i.e. traditional mode), 11n
Type, 11ac types；Wherein, 20M and 40M can be divided into again for the STA of 11n types；
In this embodiment, by taking the type of target STA is 11ac types as an example, corresponding quality and the transmission rate of eating dishes without rice or wine
Mapping relations can be as shown in Figure 3；Wherein (quality of eating dishes without rice or wine shown in figure is percentages, i.e., 20 are for 20%, 20-25
20%-25%)：
The available message transmitting spped rate that AP sends message to the STA of 11ac types includes：6Mbps、9Mbps、12Mbps、
18Mbps、24Mbps、36Mbps、48Mbps、54Mbps.According to practical experience, by AP to the transmission message of the STA of 11ac types
Available message transmitting spped rate distinguish 5 parts, respectively [6] [9,12,18] [24] [36] [48,54], correspond to respectively different
Quality of eating dishes without rice or wine section, for example, when quality of eating dishes without rice or wine is in 60-70,36 be best message transmitting spped rate；When eating dishes without rice or wine, quality is
During 50-60,48 be best message transmitting spped rate.
It should be noted that in embodiments of the present invention, AC is also needed in the message transmitting spped rate for selecting AP with reference to AP
Signal strength (can be according to RSSI (Receive Signal Strength Indicator, received signal strength indicator device)
Determine), for example, when AP determines to send message with the rate of 48Mbps, need to ensure that signal strength is not less than 15；When AP is determined
When sending message with the rate of 54Mbps, need to ensure that signal strength is not less than 17.
Correspondingly, when AC determines corresponding transmission rate according to the quality of eating dishes without rice or wine of AP, it is also necessary to determine current AP's
Whether signal strength meets the Minimum requirements of transmission rate；If not satisfied, then reduction of speed is needed to handle.
For example, when the first of AP1 eat dishes without rice or wine quality for 85% when, AC is that the first transmission rate that AP1 is determined is 54Mbps, if
The signal strength of AP1 is 16 at this time, i.e., less than 17 namely AP1 can not send message with the rate of 54Mbps to target STA, this
When, AC needs to carry out reduction of speed processing, and the first transmission rate of AP1 is determined as 48Mbps, and determine AP1 signal strength whether
It meets the requirements, since 16 more than 15, the first transmission rate for the AP1 that AC is finally determined is 48Mbps.
In addition, in embodiments of the present invention, first eats dishes without rice or wine, and (or second eat dishes without rice or wine quality pair corresponding first transmission rate of quality
The second transmission rate answered) two values (maximum value and a minimum value) can be included, for example, to eat dishes without rice or wine shown in Fig. 3
For the mapping relations of quality and transmission rate, when first eat dishes without rice or wine quality be in 25-30 when, corresponding first transmission rate is most
Big value is 12, minimum value 9；When first eat dishes without rice or wine quality be in 30-50 when, the maximum value of corresponding first transmission rate is 18,
Minimum value is 9.Correspondingly, when AC includes maximum value and minimum according to the first of AP1 the first transmission rate that quality determines of eating dishes without rice or wine
During value, AC can first control AP1 to carry out message transmission with the maximum value, if message sends failure, then control AP1 with the minimum value
Carry out message transmission；If still failing, the second transmission rate is further determined according to the second quality of eating dishes without rice or wine, and control AP1 with
Second transmission rate carries out message transmission；Wherein, if the second transmission rate is there is also maximum value and minimum value, AC is first controlled
AP1 carries out message transmission with the maximum value of the second transmission rate；If failure, then AP1 is controlled with the minimum value of the second transmission rate
Carry out message transmission.
If the 5, AP1 with the first transmission rate send message failure, AC can be eated dishes without rice or wine according to the second of AP1 quality (Qb) with
And the type of target STA, the mapping relations of type corresponding eat dishes without rice or wine quality and the transmission rate of inquiry target STA, to determine AP1
Second eat dishes without rice or wine corresponding second transmission rate of quality, and AP1 is controlled to carry out message transmission with the second transmission rate；
It should be noted that in embodiments of the present invention, when AP1 sends message with the second transmission rate still to fail,
AC can continue reduction of speed processing, and specific implementation does not repeat herein.
6th, AC can be with every 2 seconds the first skies according to 3 parts of AP1 transmissions the be most recently received quality report update AP1 that eat dishes without rice or wine
Mouthful quality and second is eated dishes without rice or wine quality, and then updates the first transmission rate and the second transmission rate of AP；
7th, when AP1 continuously successfully transmits N (N is the positive integer more than or equal to 2) a message using the first transmission rate,
AC1 can carry out raising speed processing, if after raising speed, AP1 sends message success, then can be continuous with the transmission rate after raising speed in AP1
When successfully transmitting N number of message, raising speed is carried out again；If after raising speed, AP1 sends message failure, then can be by the transmission rate of AP1
Control transmission rate when being sent successfully for the last time.
By above description as can be seen that in technical solution provided in an embodiment of the present invention, by determining eating dishes without rice or wine for AP
Quality, and AP is controlled to carry out message transmission with the corresponding transmission rate of the quality of eating dishes without rice or wine of AP, improve message transmitting spped rate selection
