For the problems referred to above, the embodiment of the present application proposes a kind of wireless client cut-in method, and the method is applied in wireless access system, and this system comprises AC, an AP, the 2nd AP, the first client and the second client.Under normal circumstances, after the first client access the one AP, second client also should access an AP, if the second client misconnection enters the 2nd AP, AC, by issuing the corresponding relation list item of the second client and an AP to the 2nd AP, makes the 2nd AP reply to the second client with the identity of an AP, to make the second client access the one AP, thus reduce the number of times of the second client's side link the 2nd AP, improve the efficiency of its access the one AP.
See Fig. 2, be an embodiment flow chart of the application's wireless client cut-in method, the access procedure of this embodiment from AC side to wireless client is described.
In step 210, when the second client with the first client associate accesses the 2nd AP, obtain the first configuration file that described second client is corresponding, in described first configuration file, comprise an AP mark of an AP, wherein, described first client has accessed a described AP.
First client and the second client have incidence relation, and all by an AP access of radio network.For Fig. 1, all members (comprising academics and students) of class 1 are all by AP1 access of radio network, teacher uses the first client (STA1) to access AP1, and student uses the second client (STA11, STA12, STA13) to access AP1.
First, first client access the one AP, the access way of the first client is same as the prior art, the MAC Address of the first client is saved in one AP, can by the function of white name list of startup the one AP, if contain the MAC Address of the first client in white list list, then a first client i.e. accessible AP.
When the first client access the one AP, AC searches the corresponding relation of client identification and the configuration file preserved in advance.Wherein, this client identification can be the MAC Address of client; The set of a series of configurations that this configuration file can be preset according to application scenarios for equipment manager, by preset configuration file on AC, when client is successfully reached the standard grade, can limit the access behavior of client by the concrete configuration in configuration file.Such as, AC is respectively class 1 and class 2 and creates corresponding configuration file, profile name is respectively " class 1 configuration file ", " class 2 configuration file ", the collocation strategy of two configuration files is restriction client can only by the AP accesses network in corresponding configuration file.
AC can pre-set the corresponding relation of the first client identification and the first configuration file in this locality.As the first client access the one AP, an AP mark of an AP, according to above-mentioned corresponding relation, is added the first configuration file by AC.Wherein, an AP mark can be the BSSID (Basic Service Set Identifier, Basic Service Set Identification) of an AP.By adding an AP mark in the first configuration file, limiting follow-up second client of binding with the first configuration file and can only use an AP accesses network.
In the present embodiment, after the first client access the one AP, if the second client access the 2nd AP, and do not access an AP, then in the second client access procedure, AC can obtain the title of the first configuration file bound with the second client from certificate server, thus start the first configuration file, contain an AP mark of an AP in this first configuration file, an AP mark is that AC adds in the first configuration file when aforesaid first client access the one AP.After the first configuration file starts, the client of binding with the first configuration file can by the AP access network in this first configuration file.
In step 220, build the first response list item, wherein, comprise in described first response list item the mark of described second client and a described AP identify between corresponding relation.
When after the second client access the 2nd AP, AC inquires about the first configuration file corresponding to the second client, find that the AP in the first configuration file is designated an AP mark, instead of the second AP mark of the 2nd AP that accessing of client, therefore, build one to comprise the second client identification and an AP and identify first of corresponding relation and respond list item.
In step 230, issue described first response list item to described 2nd AP, control the described AP of described second client access to make described 2nd AP according to described first response list item.
AC issues the first response list item to the 2nd AP, informs that the second client of the current access of the 2nd AP should access an AP, and should not access the 2nd AP, control the second client again access an AP to make the 2nd AP.
After the second client correctly accesses an AP, for the first response list item preserved in the 2nd AP, can keep according to the Determines of the second client or delete.If AC to detect the second client online, then can keep the first response list item on the 2nd AP, so as the second client misconnection is fashionable again, the time that it accesses correct AP can be shortened; If AC detects the second client off-line, then can notify that the 2nd AP deletes the first response list item, to save the memory space of the 2nd AP.
After the second client correctly accesses an AP, namely the first client and the second client all correctly access an AP, when can carry out proper network access, if the first client changes access AP, such as, disconnect with an AP, access the 2nd AP, then AC can build the second response list item, this the second response list item represents the corresponding relation that the second client identification and the 2nd AP identify, and this second response list item is handed down to an AP, notify that current connected second client of an AP should access the 2nd AP, the second client access the 2nd AP is controlled to make an AP, thus the switching of AP is accessed according to the first client, complete the switching accessing AP with the second client of the first client associate.
See Fig. 3, be another embodiment flow chart of the application's wireless client cut-in method, the access procedure of this embodiment from AP side to wireless client is described.
In step 310, when the second client access the 2nd AP, obtain the first response list item, described second client and the first client associate accessing an AP, wherein, the corresponding relation between the AP of mark and a described AP comprising described second client in described first response list item identifies.
As previously mentioned before the second client access the 2nd AP, the first client has accessed an AP, and detailed process repeats no more.When the second client accesses the 2nd AP first, AC issues the first response list item corresponding to this second client to the 2nd AP, inform the correct AP that this second client of the 2nd AP should access, after 2nd AP receives this first response list item, control the second client to roll off the production line, again access to make the second client.
In the present embodiment, after control second client rolls off the production line, for the first response list item of correspondence is provided with ageing time.If in the ageing time of regulation, the second client not receiving AC transmission has accessed the message of an AP, then delete the first response list item.Avoid in AP, preserving a large amount of response list items, and cause the wasting of resources.
When the second client accesses the 2nd AP again, the 2nd AP, by inquiring about local response list item, obtains the first response list item that the second client is corresponding.
In step 320, according to described first response list item, control the described AP of described second client access.
After the first response list item that acquisition second client is corresponding, from this first response list item, obtain an AP mark, an AP is designated the mark of the AP that the second client should access.After acquisition the one AP identifies, send to the access request of the 2nd AP to reply with the identity of an AP to the second client, identify access the one AP to make the second client according to the AP in response.
Now still for the application scenarios of wireless network shown in Fig. 1, the signalling interactive process of composition graphs 4 introduces the processing procedure of wireless client access.
Step 401, STA1 sends the message of access AP1.
Step 402, AP1 forwards the message of the access AP1 that STA1 sends to AC.
Step 403, the BSSID of AP1 is write class 1 configuration file by AC.
Suppose, the AP1 of class 1 binds two wireless services, namely two different SSID (Service Set Identifier are set, service set), such as, be set to respectively " Teacher_class1 " and " Student ", Teacher_class1 is the service identifiers of class 1 teacher access, and Student is the service identifiers of all students access.In like manner, the AP2 of class 2 binds two wireless services, is respectively " Teacher_class2 " and " Student ", Teacher_class2 is the service identifiers of class 2 teacher access, and Student is the service identifiers of all students access.
Suppose, the teacher of class 1 uses client STA 1 to access AP1, then AC can according to the MAC Address of STA1, the MAC Address of client that the teacher that inquiry is preserved in advance uses and the corresponding relation of class's configuration file, the mark (BSSID that such as, AP1 is corresponding) of the AP1 accessed by STA1 adds the configuration file (hereinafter referred to as class 1 configuration file) of class 1 correspondence.
Step 404, STA11 sends the message of access AP2.
When certain student of class 1 uses client STA 11 to access the AP1 of this class, may be larger due to the AP2 signal strength signal intensity of class 2, or due to the misoperation of this student, cause STA11 to access AP2.
Step 405, AP2 inquiry local response list item, the response list item not finding STA11 corresponding.
Step 406, AP2 forwards the message of the access AP2 that STA11 sends to AC.
Step 407, AC finds the BSSID of AP1 from class 1 configuration file, generates the response list item of the MAC Address of STA11 and the BSSID of AP1.
AC, in STA11 access procedure, obtains profile name corresponding to STA11 from certificate server, i.e. class 1 configuration file, and AC starts class 1 configuration file.AC inquires the student of class 1 from this class 1 configuration file should by AP1 access network, and the AP that current STA11 accesses is AP2, therefore, builds the response list item comprising the MAC Address of STA11 and the BSSID corresponding relation of AP1.
Step 408, the response list item of the BSSID corresponding relation of the MAC Address and AP1 that comprise STA11 is handed down to the AP2 of the current access of STA11 by AC.
Step 409, after AP2 receives above-mentioned response list item, control STA11 rolls off the production line.
Step 410, STA11 sends probe request Probe Request.
After STA11 rolls off the production line, can reconnect.AP is added by sending probe request Probe Request request.
Step 411, AP2 finds the response list item of the BSSID corresponding relation of MAC Address and the AP1 comprising STA11.
If STA11 still accesses AP2, then AP2 searches local response list item, finds the response list item of the BSSID corresponding relation comprising STA11MAC address and AP1.
Step 412, AP2 sends probing response frame Probe Response to STA11 with the BSSID of AP1.
Step 413, STA11 accesses AP1.
STA11, after receiving the response frame that AP2 sends with the identity of AP1, thinks the response that AP1 sends, and therefore, continues to access AP1 alternately with AP1.
