Embodiment
Of background technology, in existing technical scheme, no matter whether have STA to be connected to AP; AP can send Beacon, based on such configuration rule, if having no STA to use this AP; Then can there be the situation of power wastage in this AP, and simultaneously, the Beacon that constantly sends also can cause certain interference to the signal transmission of other AP; And the transmission of the wireless signal that continues also can increase the radiation to human body.
In order to solve such problem, the present invention proposes the sending method of a kind of Beacon, only confirm that at AP self need be connected to online STA, and under AP and the situation that at least one online STA is connected, just can carry out the transmission of Beacon.
As shown in Figure 1, the schematic flow sheet of the sending method of a kind of Beacon that proposes for the present invention, this method specifically may further comprise the steps:
Step S101, after AP confirms that self need be connected to online STA, said AP begins to send Beacon.
In concrete application scenarios, the processing procedure of this step is divided into following two kinds of scenes according to the connected mode of AP and STA:
Scene one, AP directly and STA connect.
For this kind scene; If said AP current not with situation that any STA is connected under, receive the Probe Request that a STA sends, then represent at least one online STA of current existence; And this STA hopes to carry out the connection of AP; The mode of using broadcasting to send Probe Request is carried out active scan, detects the AP that can connect, and the current effective coverage that can be connected with this STA that is in of this AP.
In such cases, AP can attempt being connected with this STA, and need before connecting with said STA, begin to send Beacon.
Scene two, AP comprise a plurality of BSS, and each BSS connects with STA respectively.
For this kind scene; If said AP the BSS of self current not with situation that any STA is connected under; What receive that STA sends carries the Probe Request with the corresponding SSID of this BSS, then represent at least one online STA of current existence, and this STA hopes to be connected with this AP; The mode of using clean culture to send the Probe Request of the SSID that carries appointment is carried out active scan, detects the BSS that whether can be connected to this AP.
In such cases, this BSS of AP can attempt being connected with this STA, and said AP begins to send the Beacon that carries the corresponding SSID of this BSS to said STA before this BSS and said STA connect.
Need be pointed out that further that under a kind of more excellent enforcement scene, the transmission of embodiment of the invention suggestion Beacon can begin at AP before sending Association Response or Reassociation Response to said STA.
Step S102, when said AP confirm self current be not connected to any online STA after, said AP stops to send Beacon.
In concrete application scenarios, similar with aforesaid step S101, the processing procedure of this step can be divided into the two kind scenes similar with above-mentioned explanation according to the connected mode of AP and STA equally, specifies as follows:
Scene one, AP directly and STA connect.
Under this kind scene, can comprise following three kinds the opportunity that AP stops to send Beacon:
(1) when current of said AP is connected with a STA; If said AP receives the Deauthentication that said STA sends; Or said AP initiatively removes and being connected of said STA, and then said AP stops to send Beacon through after the preset delay time.
It mainly is in order normally to roll off the production line at the STA that AP connected that this kind stops to be provided with of opportunity, or when connecting proper solution and removing, can in time stop the transmission of Beacon.
Certainly; The then interruption that is connected of AP and one of them STA also is connected with a plurality of online STA if AP is current, even also can not stop the transmission of Beacon; It is the inapplicable above-mentioned situation that stops Beacon; Because other STA are still online, and be connected, need confirm the connection of AP through Beacon with AP.
Delay time setting mainly is for fear of because propagation delay time or other factors cause the delay of new transfer.
(2) roll off the production line as current last STA that connects of said AP, and said AP is not when receiving the Deauthentication that said STA sends, then said AP stops to send Beacon through after the preset delay time.
It mainly is in that the STA that AP connected is improper when rolling off the production line that this kind stops to be provided with of opportunity, can in time stop the transmission of Beacon.
Certainly; Then AP and the improper interruption of being connected of one of them STA also be connected with a plurality of online STA if AP is current, even also can not stop the transmission of Beacon; It is the inapplicable above-mentioned situation that stops Beacon; Because other STA are still online, and be connected, need confirm the connection of AP through Beacon with AP.
Delay time setting mainly is for fear of because propagation delay time or other factors cause the delay of new transfer; And; Be provided with time of delay in such cases according to actual needs, and concrete size can be identical with the time of delay in (1), also can be different.
(3) if said AP is current not to be connected with any STA, and beginning to send Beacon and through after preset connection buffer time, said AP does not still connect with any STA, then said AP stops to send Beacon.
It mainly is in order to attempt being connected under the unsuccessful situation of STA at AP, can in time to stop the transmission of Beacon that this kind stops to be provided with of opportunity.
Same, if AP is the current online STA that also is connected with other, the then above-mentioned situation that stops Beacon will be no longer suitable, because other STA are still online, and be connected with AP, need confirm the connection of AP through Beacon.
Connect being provided with of buffer time and can connect the needed time of STA with reference to AP and be provided with, the variation of concrete numerical value does not influence protection scope of the present invention.
Scene two, AP comprise a plurality of BSS, and each BSS connects with STA respectively.
Under this kind scene, can comprise following three kinds the opportunity that AP stops to send Beacon:
(1) when current of the BSS of said AP is connected with a STA; If said AP receives the Deauthentication that said STA sends; Or said AP initiatively removes and being connected of said STA; Said AP stops to send the Beacon that carries the corresponding SSID of said BSS through after the preset delay time.
It mainly is that the STA that BSS connected at AP normally rolls off the production line that this kind stops to be provided with of opportunity, or when connecting proper solution and removing, can in time stop the transmission of Beacon.
Certainly; The then interruption that is connected of this BSS and one of them STA also is connected with a plurality of online STA if this BSS of AP is current, even also can not stop the transmission of Beacon; It is the inapplicable above-mentioned situation that stops Beacon; Because other STA are still online, and be connected, need confirm the connection of AP through Beacon with this BSS.
Delay time setting mainly is for fear of because propagation delay time or other factors cause the delay of new transfer.
(2) roll off the production line as current last STA that connects of the BSS of said AP; And when said AP does not receive the Deauthentication of said STA transmission; Said AP stops to send the Beacon that carries the corresponding SSID of said BSS through after the preset delay time.
It mainly is for when improper the rolling off the production line of the STA that BSS connected of AP that this kind stops to be provided with of opportunity, can in time stop the transmission of Beacon.
Certainly; Then this BSS and the improper interruption of being connected of one of them STA also be connected with a plurality of online STA if the BSS of AP is current, even also can not stop the transmission of Beacon; It is the inapplicable above-mentioned situation that stops Beacon; Because other STA are still online, and be connected, need confirm the connection of AP through Beacon with this BSS.
Delay time setting mainly is for fear of because propagation delay time or other factors cause the delay of new transfer; And; Be provided with time of delay in such cases according to actual needs, and concrete size can be identical with the time of delay in (1), also can be different.
(3) be not connected if the BSS of said AP is current with any STA; And beginning to send the Beacon that carries the corresponding SSID of said BSS; And through after preset connection buffer time; Said BSS does not still connect with any STA, and then said AP stops to send the Beacon that carries the corresponding SSID of said BSS.
It mainly is for the BSS at AP attempts being connected under the unsuccessful situation of STA that this kind stops to be provided with of opportunity, can in time stop the transmission of Beacon.
Same, if the BSS of AP is the current online STA that also is connected with other, the then above-mentioned situation that stops Beacon will be no longer suitable, because other STA are still online, and be connected with this BSS, need confirm the connection of AP through Beacon.
Connecting being provided with of buffer time can be provided with reference to the BSS connection needed time of STA of AP, and the variation of concrete numerical value does not influence protection scope of the present invention.
Through above-mentioned scheme, can confirm that AP carries out the start and end time that Beacon sends, still; In the prior art; During the transmission of Probe Response not optionally, as long as receive Probe Request, just can respond accordingly; The same so frequent transmission that can cause follow-up Beacon, the while also is not easy to the access control of AP.
Whether therefore, the embodiment of the invention further proposes the connection mechanism of permitting the entrance of AP, can before carrying out aforesaid step S101, allow AP and the checking that corresponding STA connects to handle, thereby realize the access control of AP.
Concrete; Receive the Probe Request of a STA transmission as said AP after, according to source MAC (Media Access Control, the medium access control) address of said Probe Request; Allow to inquire about in the tabulation at preset MAC Address; Wherein, MAC Address allows tabulation to be the MAC Address tabulation that the access control needs institute according to AP is provided with in advance, comprises to allow and all mac address informations that AP connects.
If inquire the address that the source MAC with said Probe Request is complementary, said AP returns Probe Response to said STA, and confirms self need be connected to said STA, thus further execution in step S101.
If do not inquire the address that the source MAC with said Probe Request is complementary; Said AP abandons responding; And confirm self need not be connected to said STA; Thereby,, can not carry out the feedback of subsequent P robe Response and the transmission of Beacon even receive Probe Request yet.
Through above-mentioned processing, realized the screening of the STA that AP inserted, accomplished access control to AP, for the situation that needs filter out, can not carry out the feedback of Probe Response and the transmission of Beacon, thereby save corresponding resource.
Compared with prior art, the present invention has the following advantages:
Through using technical scheme of the present invention, AP only after confirming self need to be connected to online STA, just can begin to send Beacon; And confirm self current be not connected to any online STA after, stop to send Beacon, thereby; Only under specific situation, just can carry out the transmission of Beacon; Avoid AP to send Beacon always, especially when not being connected to online STA, still need constantly send the situation of Beacon, reduce the electric power resource waste that causes thus; Reduce and to send the interference of Beacon always for other AP, and to the radiation and the environmental pollution of human body.
In order further to set forth technological thought of the present invention, combine concrete application scenarios at present, technical scheme of the present invention is described.
AP just sent Beacon when the key point of technical scheme proposed by the invention was only to have STA online, and on the contrary, the AP free time is not then sent Beacon (when promptly having no STA online, AP does not send Beacon).
Corresponding aforesaid description, the embodiment of the invention is described concrete technical scheme based on two kinds of scenes equally.
Scene one
In concrete processing scene, STA at first needs active scan to find AP, and promptly STA at first sends Probe Request; After AP receives Probe Request; Send Probe Response, after STA receives Probe Response, get access to the parameters such as SSID of AP; And respond ACK (Acknowledge Character, acknowledge character) and give AP.
In this process, AP begin to send Beacon opportunity can for:
If AP is last current any STA that is not connected to; So; To any opportunity this AP and first STA success related (being that this STA can use wireless network transmitting and receiving service message), AP all can begin the transmission of Beacon to receive first Probe Request (promptly beginning has first STA to attempt connecting with AP) from this AP.
For example: be not connected on the AP under the situation of any STA, AP receives the Probe Request that the STA of first access sends, and begins to send Beacon then; Perhaps, after AP received the Probe Request that the STA of first access sends, AP sent Probe Response, after receiving the ACK that STA responds, began to send Beacon, or the like.In aforesaid time range, the time that AP specifically begins to send Beacon can't influence protection scope of the present invention.
Set through above-mentioned rule, guaranteed as long as have STA online on the AP, then AP just can begin to continue to send Beacon.
It is pointed out that in concrete application scenarios preferred, embodiment of the invention suggestion AP begins to send Beacon at transmission (Re) association Response message and stage before.
After the transmission of beginning Beacon, can comprise following three kinds of situation the opportunity that AP stops to send Beacon:
1, gone up a STA only related as AP, and AP receives that AP stopped to send Beacon when Deauthentication message that this STA initiatively rolls off the production line or AP initiatively removed STA therewith related after waiting for certain hour.
2, roll off the production line as last STA related, and AP is not when receiving the Deautiontication message that this STA sends that AP stops to send Beacon after waiting for certain hour with AP.
3, in a period of time after AP begins to send Beacon, still have no STA to insert, then AP stops to send Beacon.
Above-mentioned three kinds of situation have satisfied the demand of different application scenes respectively, brightly specifically no longer repeat at this referring to aforesaid description, and through such rule setting, when having guaranteed only on AP, to have no STA to connect, AP just possibly stop to send Beacon.
Scene two,
In concrete processing scene; STA finds AP through active scan, still, is to send the mode of carrying the Probe Request that specifies SSID through clean culture to detect; After AP receives Probe Request; Confirm that according to its entrained SSID this STA is connected with the corresponding BSS of self in trial, so, reply Probe Response and give this STA.
In this process, AP begin to send Beacon opportunity can for:
If certain BSS of AP goes up current any STA that is not connected to; So; Receive that from this AP first has the Probe Request of the clean culture of the pairing SSID of this BSS (promptly beginning to have first STA to attempt being connected to this BSS) to this BSS and first STA successful any opportunity related (being that this STA can use wireless network transmitting and receiving service message), AP all can begin to carry the transmission of the Beacon of this SSID.
For example: on certain BSS of AP, be not connected under the situation of any STA, AP receive that STA sends first have the Probe Request of this SSID, AP begins to send the Beacon that carries this SSID then; Perhaps, first that receive that STA sends at AP has the Probe Request of this SSID, and after AP sent Probe Response, AP sent the Beacon that carries this SSID, or the like.In aforesaid time range, the time that AP specifically begins to send the Beacon that carries this SSID can't influence protection scope of the present invention.
Set through above-mentioned rule, guaranteed that as long as have STA online on certain BSS of AP, AP just continues to send the Beacon that carries this SSID.
It is pointed out that in concrete application scenarios preferred, embodiment of the invention suggestion AP begins to send the Beacon that carries this SSID at transmission (Re) association Response message and stage before.
After the transmission of beginning Beacon, can comprise following three kinds of situation the opportunity that AP stops to send Beacon:
1, gone up a STA only related as certain BSS of AP, and AP receives the Deauthentication message that this STA initiatively rolls off the production line, or AP has been when initiatively having removed STA therewith related, AP stops to send the Beacon that carries this SSID after waiting for certain hour.
2, on certain BSS of AP, last STA related with this AP rolls off the production line, and AP is not when receiving the Deautiontication message that this STA sends, and AP stops to send the Beacon that carries this SSID after waiting for certain hour.
3, in a period of time after AP begins to send the Beacon that carries the pairing SSID of certain BSS, this BSS still has no STA to insert, and then AP stops to send the Beacon that carries this SSID.
Above-mentioned three kinds of situation have satisfied the demand of different application scenes respectively; Bright specifically referring to aforesaid description; No longer repeat at this; Through such rule setting, when having guaranteed only on certain BSS of AP, to have no STA to connect, AP just possibly stop to send the Beacon that carries the pairing SSID of this BSS.
Further; The MAC Address of the STA of AP permission can be set in the technical scheme that the embodiment of the invention proposed; After AP receives the Probe Request that STA sends; The MAC Address that search AP allows, in the time of the MAC Address coupling that is provided with among the source MAC of Probe Request and the AP, AP response Probe Response.Carry out aforesaid Beacon then and send and stop the flow process of handling process.
Compared with prior art, the present invention has the following advantages:
Through using technical scheme of the present invention, AP only after confirming self need to be connected to online STA, just can begin to send Beacon; And confirm self current be not connected to any online STA after, stop to send Beacon, thereby; Only under specific situation, just can carry out the transmission of Beacon; Avoid AP to send Beacon always, especially when not being connected to online STA, still need constantly send the situation of Beacon, reduce the electric power resource waste that causes thus; Reduce and to send the interference of Beacon always for other AP, and to the radiation and the environmental pollution of human body.
