Beacon frame includes a SSID in the ssid list of region.
Based on WLAN networking shown in FIG. 1, the embodiment of the present application provides a kind of method of information sifting, and this method is held by AC
Row, as shown in Fig. 2, this method comprises:
S201, first kind service set SSID is obtained, and sends first kind SSID to the AP of access AC.
Wherein, first kind SSID is above-mentioned zone ssid list, the SSID of the WLAN including terminal connection, and terminal, which is in, to be referred to
Determine in region.
Wherein, first kind SSID is generated by big data mode by machine for third party data set provider, the first kind
Include the SSID of public WLAN in SSID, for example, market or supermarket WLAN SSID；It may also include not common WLAN
SSID, such as family WLAN SSID.
S202, the scanning information that AP is obtained within a preset period of time is received.
Scanning information includes the MAC Address of terminal SSID to be connected and terminal, and scanning information is that AP receives terminal hair
It is sent after the uni-cast probe request sent.
Wherein, after AC sends first kind SSID to AP, AP generates multiple beacon frames, and in its coverage area, can also
Referred to as in radio-frequency region, multiple beacon frames are continuously broadcasted, each beacon frame includes a SSID in first kind SSID.
After terminal receives beacon frame, from beacon frame, SSID is obtained.If the corresponding WLAN of the SSID be terminal once
The WLAN of access, then terminal sends uni-cast probe request to AP, which includes the attribute of the SSID and terminal
Information.After AP receives the uni-cast probe request, a scanning information is generated, which, which includes that terminal is to be connected, is somebody's turn to do

In the embodiment of the present application, the attribute information of terminal is specially MAC Address.
Wherein, uni-cast probe request is specifically as follows the probe requests thereby (Probe that destination address is unicast address
Request)。
In one embodiment, AP one scanning information of every generation within a preset period of time then sends one to AC and sweeps
Retouch information.
In another embodiment, AP is being sent in the preset time period after beacon frame, generates scanning information.?
After the duration of preset time period, the scanning information generated within a preset period of time is sent to AC.
Preset time period can be arranged according to the real time, for example, can be 1 week, or can be 10 days.
S203, according to the MAC Address of terminal SSID to be connected and terminal, the second class is obtained from first kind SSID
SSID。
Wherein, AC can receive the multi-strip scanning information that each AP is generated within a preset period of time.
Every scanning information includes the MAC Address of terminal SSID to be connected and terminal.Optionally, scanning information can be with
The number of the SSID is connected including the terminal request.
For example, the uni-cast probe request includes SSID1 and terminal A if AP receives the uni-cast probe request of terminal A transmission
MAC Address, then produce a scanning information 1, scanning information 1 include SSID1, the MAC Address of terminal A and number 1.
Within a preset period of time, AP receives the uni-cast probe request of terminal A transmission again, which includes
The MAC Address of SSID1 and terminal A, then produce a scanning information 2, and scanning information 2 includes the MAC Address of SSID1, terminal A
And number 2.
AC obtains the second class SSID from first kind SSID and specifically includes: according to terminal SSID to be connected and terminal
MAC Address determines the quantitative value of the MAC Address of the corresponding terminal of each SSID in first kind SSID.Then, terminal is utilized
The quantitative value size of MAC Address is ranked up each SSID in first kind SSID, from the first kind SSID after sequence
In, the SSID of preset quantity is obtained as the second class SSID.
As an example, the corresponding MAC Address situation of each SSID in first kind SSID is determined such as according to scanning information
Shown in table 1.
Table 1
According to table 1, the quantitative value of the corresponding MAC Address of SSID1 is 3, respectively MAC1, MAC2 and MAC3.
The quantitative value of the corresponding MAC Address of SSID2 is 2, respectively MAC1 and MAC2.
The quantitative value of the corresponding MAC Address of SSID3 is 2, respectively MAC1 and MAC4.
So being SSID1 > SSID2=SSID3 to the result that each SSID in first kind SSID is ranked up.
In the embodiment of the present application, if the quantitative value of the corresponding MAC Address of at least two SSID is identical in first kind SSID,
Then the number in scanning information is appeared according to each SSID to be ranked up at least two SSID.
Wherein, AC can determine that each SSID appears in the number in scanning information according to the scanning information received.If
Scanning information includes the number of terminal request connection SSID, then can count each SSID according to the number and appear in scanning information
Number；If scanning information does not include the number of terminal request connection SSID, AC can count each of first kind SSID respectively
SSID appears in the number in scanning information.As an example, the statistical result of AC is as shown in table 1.
According to the example above, the quantitative value of the corresponding MAC Address of SSID2 and SSID3 is identical.But SSID2 is appeared in and is swept
Retouching the number in information is 1 time+5 times=6 times.It is 1 time+1 time=2 times that SSID3, which appears in the number in scanning information,.As it can be seen that
SSID2 appears in the number in scanning information and appears in number in scanning information greater than SSID3, so final ranking results
For SSID1 > SSID2 > SSID3.
It should be noted that including 3 SSID, the in the actual implementation process first kind in first kind SSID in above-mentioned example
The SSID quantity for including in SSID is without being limited thereto.
Wherein, the quantitative value of the corresponding MAC Address of SSID is more, illustrates that the terminal quantity of the request connection SSID is more.
It is more to appear in the number in scanning information by each SSID in first kind SSID, illustrates the corresponding WLAN of the SSID by terminal request
The number of connection is more.
It is to be understood that appearing in scanning letter by the quantitative value and each SSID of the corresponding MAC Address of each SSID
Number in breath, after being ranked up to each SSID in the first SSID, sort more forward SSID in first kind SSID, to AP
The reference value for getting the attribute information of terminal is higher, so obtaining the SSID for the forward preset quantity that sorts as second
Class SSID.
For example, preset quantity is 30, and if first kind SSID includes 200 SSID, first 30 after sequence can be obtained
SSID is as the second class SSID.
S204, the second class SSID is sent to AP, so that AP continuously broadcasts multiple beacon beacon according to the second class SSID
Frame.
Wherein, each beacon frame includes a SSID in the second class SSID.
Since available WLAN can be varied in specified region, such as the part WLAN of terminal history connection
It may permanently be substituted by other WLAN, correspondingly, the collected first kind SSID of third party data set provider can also change.
In order to enable the attribute information of AP efficiently detecting terminal, can at regular intervals, for example, one month or a season,
Primary above-mentioned S201 to above-mentioned S204 is re-executed, so that AP can broadcast beacon frame according to updated SSID.
Therefore, using the method for information sifting provided by the embodiments of the present application, AC can obtain first kind SSID, and to access
The AP of AC sends first kind SSID.Then, AC receives the scanning information that AP is obtained within a preset period of time.Since scanning information is
AP is sent after receiving the uni-cast probe request that terminal is sent, so the SSID that scanning information includes is to be conducive to help AP detection
The SSID of the attribute information of terminal, so that AC can determine which SSID is conducive to help in first kind SSID according to scanning information
The attribute information of AP acquisition terminal.To which AC obtains the second class SSID according to scanning information from first kind SSID, and sent out to AP
The second class SSID is sent, allows AP for the SSID broadcast beacon frame in the second class SSID.Avoid the wave of interface-free resources
Take.
It should be noted that AC can determine which SSID in first kind SSID is conducive to that AP is helped to obtain according to scanning information
The attribute information for taking terminal is because the title for the SSID that first kind SSID includes will not provide wireless access business with AP
SSID name is identical.If the SSID that the uni-cast probe request of what AP was received come self terminal includes belongs to first kind SSID, say
Bright terminal once accessed the corresponding WLAN of the SSID, and the terminal receives the beacon frame of AP broadcast, to trigger terminal
Send the process of uni-cast probe request.Therefore, which beacon frame that AP broadcast can be determined by scanning information obtains AP
Reference value to the attribute information of terminal is higher, that is, can determine which SSID in first kind SSID is conducive to that AP is helped to obtain
The attribute information of terminal.

Wherein, in addition to uni-cast probe request, AP can also receive other messages.Such as terminal can be with active transmission
Destination address is the broadcast probe request of broadcast address, may be corresponding to terminal replies after AP receives broadcast probe request
Detection reply.But above-mentioned broadcast probe request may not include the SSID in first kind SSID, so AP is generating scanning letter
It will not include that the message of SSID in first kind SSID is filtered when breath.
In order to realize the filtering of message, AP can recognize the message for carrying out self terminal, if recognizing uni-cast probe request, obtain
The MAC Address of the terminal that uni-cast probe request includes SSID to be connected and terminal, and judge that terminal SSID to be connected is
It is no to belong to first kind SSID, however, it is determined that terminal SSID to be connected belongs to first kind SSID, then generates scanning information.Scanning letter
