Specific embodiment
Understandable for enabling the above objects, features and advantages of the present invention to become apparent from, below in conjunction with the accompanying drawings and specifically real
The present invention is further detailed explanation to apply mode.
One of core idea of the embodiment of the present invention is, proposes a kind of sending method of probing response frame and device, from
And effectively lift quality of wireless services during STA roaming and Consumer's Experience.Present invention could apply to STA is from same wireless
AP under network roams in the embodiment of another AP, specifically, moves from the signal cover of the AP being currently accessed in STA
When going out, STA will select the AP of a mesh according to the roaming decisions of itself, thus completing to roam by accessing this purpose AP.Additionally,
Present invention can also apply to STA reaches the standard grade and the scene such as STA reaches the standard grade first from certain AP is offline again, specifically, successfully connect in STA
During entering purpose AP, it is broadly divided into three phases, respectively：Sweep phase (SCAN), authentication phase
And association phase (Association) (Authentication).The present invention mainly passes through the response to STA in sweep phase
Time delay is interfered, and induction STA has access to quality of wireless services preferably AP, thus improving wireless clothes during STA roaming
Business quality and Consumer's Experience.
With reference to Fig. 1, show a kind of flow chart of steps of the sending method embodiment of probing response frame of the present invention, the party
Method is applied to AP, specifically may include steps of：
Step 101, receives the probe request from STA.
Specifically, the sweep phase during STA accesses purpose AP, STA actively sends to detect by broadcast mode and asks
Seek frame (Probe Request frame), responded with the AP waiting correlation to receive Probe Request frame.
Step 102, when needing to respond STA according to probe request determination, measures during probe request according to receiving
Signal strength signal intensity, and the corresponding relation of default signal strength range and waiting time, when determining the corresponding wait of signal strength signal intensity
Long.
Specifically, AP, after receiving probe request, can determine the need for responding STA in the following manner：
Judge in probe request, whether to carry specified services set identifier (Service Set Identifier,
SSID)；
If not it is determined that needing to respond STA；
If so, judge whether the SSID carrying in probe request is identical with the SSID of AP, and when being judged as YES, determine
Need to respond STA, when being judged as NO, determine and do not need to respond STA.
That is, STA is in active broadcast probe request, specified SSID can be carried it is also possible to not carry specified
SSID.It is meant that not all AP receiving probe request is responded in the case of carrying specified SSID,
But only SSID could be responded to probe request with specified SSID identical AP；In the situation not carrying specified SSID
Down it is meant that all AP receiving probe request are responded.
In this step, signal strength signal intensity may be considered the signal strength signal intensity of STA, and concrete measurement process is prior art,
This no longer describes in detail.
In the present invention, it has been previously stored the presets list in AP side, in this presets list, record has multiple default signals
Corresponding relation between strength range and waiting time, and, in signal strength range signal strength signal intensity mean value bigger, signal
Strength range corresponding waiting time is longer, and generally in each signal strength range, the number of signal strength signal intensity is identical.So, AP exists
After receiving probe request, which default signal strength range is fallen into according to the signal strength signal intensity that this corresponding relation searches STA
Interior, so that it is determined that going out this signal strength signal intensity corresponding waiting time.
Step 103, after the waiting time determined, sends probing response frame to STA.
Specifically, AP, after the waiting time determined, just sends probing response frame (Probe Response to STA
Frame), so, when STA selects the AP of last response to access in roaming, access the probability of the preferable AP of quality of wireless services
Larger.
In sum, the technical scheme in the embodiment of the present invention, by receiving the probe request from terminal STA；Root
According to receiving the signal strength signal intensity measuring during probe request, and the corresponding relation of default signal strength range and waiting time,
Determine signal strength signal intensity corresponding waiting time；After the waiting time determined, send probing response frame to STA, thus real
Now AP end is returned with the intervention of the time delay of probing response frame, improves STA and be linked into quality of wireless services preferably AP in roaming
Probability, and then improve quality of wireless services and Consumer's Experience.
In a preferred embodiment of the invention, AP can also be after process determines waiting time, continuation etc.
Treat preset duration, then send probing response frame to STA again.In an embodiment of the present invention, this preset duration can be from pre-
If any duration randomly selecting in time range.Specifically, introduce preset duration to be used for realizing the random hash of waiting time.
Illustrate：If AP1, AP2 differ very little with the distance of AP3 to STA, the STA's that AP1, AP2, AP3 get
Difference between signal strength values also very little, the signal strength signal intensity of the STA that AP1, AP2, AP3 measure is it is possible that fall into same
The situation of signal strength values scope, therefore, the waiting time corresponding to the signal strength signal intensity of the STA that AP1-AP3 determines will be same
One waiting time.In that case, STA will receive, in synchronization, the probing response frame that AP1, AP2, AP3 send.
So, in order to avoid the generation of this phenomenon, AP1, AP2, AP3 will determine signal strength signal intensity corresponding waiting time
Afterwards, more respectively choose a random duration (as preset duration) from preset duration scope, then through waiting time and each
Preset duration after, then send probing response frame to STA respectively, so that different AP corresponding waiting time disperses.This area
Those of ordinary skill is it should be clear that the selection of random duration need to be entered in certain limit (preset duration scope as referred to above)
Row selects, and the duration after the maximum in this scope was added with waiting time not can exceed that the access response cycle of STA.
In a preferred embodiment of the invention, in the locally stored the presets list of AP also record have multiple default
Corresponding relation between signal strength range and transmission power, and, in signal strength range signal strength signal intensity mean value bigger,
The corresponding transmission power of signal strength range is bigger.So, before sending probing response frame to STA, AP can be according to default
Corresponding relation between signal strength range and transmission power, finding out the signal strength signal intensity of STA, to fall into which default signal strong
In the range of degree, thus further determining that out the corresponding transmission power of this signal strength signal intensity, subsequently sent out using the transmission power determined
Send probing response frame, so that STA has access on quality of wireless services preferably AP.
In a preferred embodiment of the invention, AP can also be in the corresponding transmitting of the signal strength signal intensity determining STA
After power, this transmission power is added with default transmission power, calculates both sums.In an embodiment of the present invention,
Default transmission power is similar with above-mentioned preset duration, is equally to randomly select one from predetermined power scope with acc power
(as default transmission power), then this default transmission power is added with the transmission power determined, and through determining
After the waiting time going out, or after waiting time of determining and preset duration, with the transmission power that calculates to
STA sends probing response frame, thus realizing the random hash of transmission power.
In order to be better understood from technical scheme, it is described in detail with specific embodiment below.

Intensity falls in the signal strength range of 50-55dB, and this signal strength range corresponding waiting time is 150ns, transmitting
Power is 20dBm.Subsequently, AP2 will be randomly choosed a duration in the range of preset duration and will be added with waiting time, and, AP2
Also a power will be randomly choosed in the random scope of transmission power to be added with transmission power.In the present embodiment, AP2 selects
A length of 1ns when random, then the final waiting time of AP2 is 151ns, it is 0.1dBm that AP2 selects random transmission power, then AP2
Final transmission power is 20.1dBm.In the same manner, AP3 passes through to inquire about the presets list, determines that the signal strength signal intensity of STA falls into 56-60dB's
In signal strength range, this signal strength range corresponding waiting time is 200ns, and transmission power is 22dBm.AP3 selects
A length of 3ns when random, then the final waiting time of AP3 is 203ns.What AP3 selected is 0.2dBm with acc power, then AP3 is
Whole transmission power is 22.2dBm.
AP2 will send probing response frame with the transmission power of 20.1dBm to STA after 151ns.And AP3 will be in 203ns
Afterwards, probing response frame is sent to STA with the transmission power of 22.2dBm.
STA is sequentially received the probing response frame that AP2 and AP3 sends, and determines purpose AP by pre-defined rule.At this
In bright embodiment, pre-defined rule is：According to the order of the probing response frame receiving, determine last detection receiving
The corresponding AP of response frame is purpose AP.
Therefore, in an embodiment of the present invention, the corresponding AP of probing response frame that STA finally receives be AP3 it is determined that
AP3 is purpose AP.STA and AP3 sets up communication connection, and carries out follow-up data interaction, thus completing to roam.
