The technical solution of the embodiment of the present invention can be applied in wireless network traffic scene, need to share limited frequency spectrum resource between multiple wireless access point (AP).Wireless aps are the access points for making wireless terminal device enter cable network in wireless network.In following embodiments of the invention, it will be responsible for assisting the coordination of multiple AP and cooperating process, by the way that AP competitive channel can be helped with the STA of multiple AP communications that cooperate, after STA is robbed and is accounted for channel, the channel right to use is handed to cooperation AP simultaneously, the idle channel of a segment sync is triggered with this, cooperation AP can interact coordination information and be cooperated in this channel.STA for example can be the user equipmenies such as smart phone, laptop, the PAD accessed in a certain AP.

Fig. 1 is wireless access point synchronous collaboration method application scenarios schematic diagram provided in an embodiment of the present invention.As shown in Figure 1, at least two adjacent AP can form a collaboration set, and there are the STA that at least one can be communicated with the AP in collaboration set for the AP in the collaboration set overlapping covered.When the overlapping covered interior STA of collaboration set AP monitors that channel is idle, the node being then now in the communication range of the STA has very maximum probability to be in idle condition, then, AP in the collaboration set can obtain channel using the power of alienation simultaneously, and interact coordination information in this channel and cooperate.Such as STA1 can be communicated with AP1, AP2 and AP3, then AP1 and AP2 can form a collaboration set, and AP1 and AP3 can form a collaboration set, and AP2 and AP3 can form a collaboration set, AP1, AP2 and AP3 can also form a collaboration set, these collaboration sets can pass through STA1's It assists to complete coordination and cooperating process.

It is noted that the collaboration set that STA1, STA2, STA3 and STA4 can assist AP1 and AP2 to form carries out channel competition if STA1, STA2, STA3 and STA4 can be communicated with AP1 and AP2.Obviously, overlapping covered user (STA) number in collaboration set AP is more, and it is bigger using the chance of the power of alienation that AP obtains channel.

In following embodiments of the invention, it will be described in detail so that AP1 and AP2 forms a collaboration set as an example.Obviously, these embodiments and are not intended to limit the invention for illustrating.

The embodiment of the present invention is illustrated from the side STA and the side AP respectively, and is illustrated simultaneously to the cooperation embodiment of the two, but this does not imply that the two must cooperate implementation, only when the two cooperation, can obtain superior technique effect.

Fig. 2 is a kind of wireless access point synchronous collaboration method flow diagram provided in an embodiment of the present invention, as shown in Fig. 2, this method may include steps of:

S21, STA competitive channel；

S22, STA send first message, wherein first message is used to indicate at least two AP and is cooperated using the first channel, and the first channel is that STA competes the channel obtained for sending first message.

The executing subject of above step is STA.

In the present embodiment, it will be elaborated by application scenarios shown in FIG. 1.It please refers to shown in Fig. 1, adjacent AP1 and AP2 form a collaboration set, and overlapping covered STA1~STA4 in AP1 and AP2 can be the user of access AP1 or AP2, and certain STA1 can also be the user of access AP3.It is assumed that the propagated loss between AP and STA has symmetry, if that STA1~STA4 can listen to the signal from AP1 and AP2, if then the transmission power of AP and STA is equal, AP1 and AP2 can also signals with uppick from STA1~STA4；If the transmission power of AP and STA is unequal, STA can judge whether own transmission signal can be received by AP according to the difference power of AP and STA.

Illustratively, in application scenarios shown in Fig. 1, STA1~STA4 passes through the collaboration set competitive channel that judgement determines that it can be communicated with AP1 and AP2, then STA1~STA4 can assist AP1 and AP2 to form.STA1~STA4 equally uses CSMA/CA mechanism Anti-Sniffer channel busy-idle condition, it is assumed that STA1 keeps out of the way end after detecting channel idle first, then STA1 just obtains the channel right to use at that moment, and the node in STA1 communication range has very maximum probability to be in idle condition at this time.After STA1 takes the lead in keeping out of the way the end acquisition channel right to use, STA1 passes through channel (the first letter competed Road) channel is sent using Transfer Message (first message) to AP1 and AP2 simultaneously, the right to use of the first channel is handed into AP1 and AP2.It is assumed that AP1 and AP2 have had correctly received the channel from STA1 using Transfer Message, then AP1 and AP2 obtains the channel right to use simultaneously, then AP1 and AP2 can be cooperated by the first channel.

It is appreciated that there are AP1 or AP2 to be not properly received the possibility that the channel from STA1 uses Transfer Message, at this point, STA1 can be judged according to received channel using response message.The response message is, for example, the broadcast message that AP1 or AP2 are issued respectively, the STA of helpful AP1 and AP2 competitive channel and other adjacent websites (including AP and STA) for informing, oneself will use the first channel to cooperate.

In the present embodiment, the AP competitive channel in the collaboration set is helped by the STA that can be communicated with the AP in collaboration set, after STA competition to channel, the channel right to use is handed to the AP in collaboration set simultaneously, a segment sync time window is triggered on this idle channel with this, AP in collaboration set interaction coordination information and can cooperate synchronization time in this of window.After STA competition to channel, the node being now in the communication range of the STA has very maximum probability to be in idle condition, in this case, coordination interaction duration between AP in collaboration set can be estimated, coordination information is successfully sent or received probability greatly improves, thus it can effectively improve the feasibility to cooperate between AP, to promote the spectrum reuse gain under highly dense scene.

Fig. 3 is another wireless access point synchronous collaboration method flow diagram provided in an embodiment of the present invention, as shown in figure 3, this method may include steps of:

S31, first AP receives the first message that the first STA is sent, wherein, first message is used to indicate the first AP and is cooperated using the first channel and at least one the 2nd AP, at least one the 2nd AP is in the communication radius of the first STA, and the first channel is that the first STA competes the channel obtained for sending first message；

S32, the first AP are cooperated using the first channel and at least one the 2nd AP.

The executing subject of above step is the first AP.

In the present embodiment, it will be elaborated by application scenarios shown in FIG. 1.It please refers to shown in Fig. 1, adjacent AP1 and AP2 form a collaboration set, and overlapping covered STA1~STA4 in AP1 and AP2 can be communicated with AP1 and AP2.The channel that AP1 and AP2 takes the lead in receiving STA1 transmission uses Transfer Message (first message), then AP1 and AP2 is known that they can compete the channel (the first channel) obtained by STA1 and cooperate.

It is understood that, in order to avoid the first channel is seized by other websites (including AP and STA), AP1 and AP2 can be after receiving first message, broadcast transmission is directed to the response message of the first channel right to use, the response message is used to inform the institute STA of helpful AP1 and AP2 competitive channel and other adjacent websites (including AP and STA), oneself will be cooperated using the first channel.

In the present embodiment, AP is after receiving the channel that the STA that can be communicated with the AP in collaboration set is sent and using Transfer Message, AP in collaboration set can obtain the segment sync time window on the first channel simultaneously, and interaction coordination information and cooperate in this of window synchronization time.AP is after the channel for receiving STA transmission is using Transfer Message, the node being now in the communication range of the STA has very maximum probability to be in idle condition, in this case, coordination interaction duration between AP in collaboration set can be estimated, coordination information is successfully sent or received probability greatly improves, thus it can effectively improve the feasibility to cooperate between AP, to promote the spectrum reuse gain under highly dense scene.

Fig. 4 is that another wireless access point synchronous collaboration method flow diagram provided in an embodiment of the present invention will do exemplary illustration to technical solution of the present invention by the cooperation embodiment of AP and STA in the present embodiment.As shown in figure 4, this method may include steps of:

S41, STA competitive channel；

S42, STA send first message, wherein first message is used to indicate at least two AP and is cooperated using the first channel, and the first channel is that STA competes the channel obtained for sending first message；

S43, at least two AP receive first message；

S44, at least two AP are cooperated using the first channel.

In the present embodiment, application scenarios shown in FIG. 1 will be continued through to elaborate, please continue to refer to Fig. 1.Adjacent AP1 and AP2 forms a collaboration set, and overlapping covered STA1~STA4 in AP1 and AP2 can be the user of access AP1 or AP2, and certain STA1 can also be the user of access AP3.Assuming that STA1~STA4 can be communicated with AP1 and AP2, then the collaboration set competitive channel that STA1~STA4 can assist AP1 and AP2 to form.STA1~STA4 equally uses CSMA/CA mechanism Anti-Sniffer channel busy-idle condition, it is assumed that STA1 keeps out of the way end after detecting channel idle first, then STA1 just obtains the channel right to use at that moment, and the node in STA1 communication range, which may be considered, at this time is in idle condition.After STA1 takes the lead in keeping out of the way the end acquisition channel right to use, while channel being sent to AP1 and AP2 and uses Transfer Message (first message), the channel competed (the first channel) right to use is handed into AP1 and AP2.AP1 and AP2 has had correctly received the channel from STA1 using Transfer Message, then AP1 and AP2 obtains the channel right to use simultaneously, then AP1 and AP2 can be cooperated by the channel (the first channel) that STA1 is competed.

It is understood that, in order to avoid the first channel is seized by other STA and others AP, AP1 and AP2 can be after receiving first message, broadcast transmission is directed to the response message of the first channel right to use, the response message is used to inform the institute STA of helpful AP1 and AP2 competitive channel and other adjacent websites (including AP and STA), oneself will be cooperated using the first channel.

Certainly, there are AP1 or AP2 to be not properly received the possibility that the channel from STA1 uses Transfer Message, at this point, STA1 can be judged according to received response message.If STA1 does not receive the response message that AP1 and AP2 is sent, or only receives the response message that one of AP is sent in AP1 and AP2, then STA1 continues competitive channel.

It can be understood that, on the one hand: after STA1 issues first message first message, a fixed time interval can be waited, if the response message that any AP is sent still is not received by after interval at a fixed time, then STA1 is not it is determined that AP1 and AP2 are properly received first message, and continue to execute channel competition and retransmit first message.On the other hand: STA1 possibly can not receive the response message that AP1 and AP2 is sent simultaneously, after the response message that STA1 receives that one of AP is sent in AP1 and AP2, a fixed time interval can be waited, if the response message of another AP transmission is still not received by after interval at a fixed time, then STA1 is not it is determined that another AP is properly received first message first message, and continues to execute channel competition and retransmit first message.

After AP1 and AP2 coordinate successfully, so that it may immediately begin to start to cooperate according to the collaborative work rule coordinated.It should be pointed out that so-called collaborative work can be downlink data transmission of the AP to STA here, it is also possible to transmitting uplink data of the STA to AP, specific cooperative working process is not within scope of the invention.If AP1 and AP2 hormany failure returns to miscoordination operating mode.

In the present embodiment, AP1 and AP2 cooperate and can be triggered by the side STA, can also be triggered by the side AP.

If AP1 and AP2, which cooperate, to be triggered by the side STA, the assistance AP1 and AP2 that one or more STA is spontaneous in namely STA1~STA4 carry out channel competition, it takes the lead in competing to the STA of channel and the channel right to use is handed into AP1 and AP2, it is desirable that AP1 and AP2 cooperate.

If it is to be triggered by the side AP, that is, one or more STA is assisted after the instruction information for receiving request first message in STA1~STA4 that AP1 and AP2, which cooperate, AP1 and AP2 carries out channel competition, and it is AP1 and AP2 competitive channel which, which is used to indicate STA,.Illustratively, since STA1~STA4 can be communicated with AP1 and AP2, therefore AP1 or AP2 the one or more STA into STA1~STA4 is can be and send instruction information；Or AP1 and AP2 the one or more STA into STA1~STA4 send instruction information；If STA1 can be communicated simultaneously with AP1~AP3, it is also possible to be AP3 to indicate STA1 to STA1 transmission instruction information to assist AP1 and AP2 competitive channel.

Further, the mark that may include AP1 and AP2 in the instruction information of first message is requested, the mark of AP1 and AP2 are, for example, basic service set identification (BSS Identification, abbreviation BSSID).After STA receives the instruction information of the BSSID comprising AP1 and AP2, so that it may uniquely determine out AP1 and AP2 according to the BSSID of AP1 and AP2.

As another optional embodiment, requesting can also be comprising the mark (ID) of the AP1 and AP2 collaboration set formed in the instruction information of first message.It can be understood that, it can also include for managing the wireless controller of all AP (Access Controller in wlan network, abbreviation AC), the ID that AC can distribute a corresponding collaboration set ID, i.e., each collaboration set ID and AP in the collaboration set for the collaboration set of two or more AP composition has unique corresponding relationship.Illustratively, AC is AP1 and the collaboration set distribution collaboration set ID of AP2 composition is S1, and the STA for receiving the instruction information comprising S1 can uniquely determine out AP1 and AP2 according to the corresponding relationship of the ID for the AP for including in S1 and collaboration set ID and collaboration set.Optionally, in the case where no AC, AP1 and AP2 can also freely negotiate to share an identical collaboration set ID.

As another optional embodiment, request include collaboration set ID in the instruction information of first message.After STA receives the instruction information of the ID comprising collaboration set, STA can only be the corresponding collaboration set competitive channel of the ID according to instruction information, not need to determine in collaboration set on earth comprising which AP.At this point, the STA of successful contention to channel can will indicate that the collaboration set ID in information is added in first message, as the mark of first message, and broadcast transmission first message.The AP for receiving first message can judge whether oneself belongs in the collaboration set according to the mark of first message, receive the first message if belonging to, the first message is ignored if being not belonging to.It is appreciated that can determine which STA to send instruction information to from AP.

In the present embodiment, STA, which can be determined according to the signal strength of the AP listened to which AP, issues access request message, and AP can send access response message to corresponding STA.STA can also judge which AP is in oneself according to the transmission power of own transmission power and its AP that can be listened to Maximum positive radius of communication in.

Preferably, the AP set that the AP that STA can be accessed to it reports oneself that can communicate, i.e. all AP in the communication radius in STA.AP can gather according to the communication AP that STA is reported oneself can cooperate to determine with which AP.Obviously, which STA AP can also can request assist channel competition according to the STA of the communication AP set reported to it when determining that oneself and certain AP are cooperated.Optionally, AP, which can also gather according to the communication AP that STA is reported to STA, sends collaboration set logo collection.Obviously, AP can gather according to the communication AP that STA is reported determines whether some STA can effectively service some collaboration set, and AP can determine that sending the ID comprising collaboration set to the STA that can effectively service some collaboration set indicates information at this time.

Optionally, the communication AP of oneself can be gathered and is directly contained in access request message by STA, be reported to its AP accessed.Collaboration set logo collection can also be included in access response message and be sent to STA by AP.Being worth mentioning is, accessing even can also directly include the instruction information for being directed to the request first message of some collaboration set in response message.

Illustratively, STA1 can listen to the signal from AP1~AP3, and the received signal strength from AP1 is higher than the received signal strength from AP2 and AP3, and STA1 determines to issue access request to AP1.If STA1 knows that own signal can also be received by AP2 and AP3 by judgement, STA1 reports the information of AP2 and AP3 to AP1, such as the BSSID of AP2 and AP3.Obviously, STA1 can directly include the BSSID of AP2 and AP3 into the access request message that AP1 is sent.

Then AP1 is known that STA1 is in the overlapping covered of AP1, AP2 and AP3, and the signal of STA1 can be received simultaneously by AP1, AP2 and AP3.Correspondingly, the corresponding cooperation set identifier (such as S1, S2, S3, S4) of collaboration set for the collaboration set of collaboration set, AP1 and AP3 composition, the collaboration set of AP2 and AP3 composition and AP1, AP2 and AP3 composition that AP1 and AP2 is formed can be sent to STA1 by AP1.Obviously, these cooperation set identifiers, which can be directly contained in access response message, is sent to STA1.And AP1 can also carry the instruction information that request STA1 assists AP1 and AP2 to carry out channel competition in access response message.

It is appreciated that the position STA can constantly change since STA is usually mobile subscriber equipment.With the variation of the position STA, the AP set that STA can be communicated can also change.As a kind of preferable embodiment, STA can be in the AP set that the AP that any time after networking is actively accessed to it reports oneself that can communicate.Alternatively, AP can also report request to the communication AP set that STA initiates the STA in any time after STA networking, STA receive report request after to AP report it Communicate AP set.

As another optional embodiment, STA communicates AP set in addition to the AP that can be accessed to oneself is reported, and the communication AP of oneself can also be reported to gather by AP some or all of into communication AP set.Similarly, AP reports request in addition to that can send communication AP set to the STA for accessing oneself, STA transmission communication AP set can also report request some or all of into AP communication range.

It is also understood that, instruction information of the AP in addition to request first message can be sent to the STA for accessing oneself, this instruction information can also be included in some control/management frame (such as Beacon frame), or media access control (the Medium Access Control of some new definition, abbreviation MAC) layer control/management frame, broadcast to the STA in AP communication range.

Further, it may include the corresponding collaboration set ID of collaboration set of ID or multiple AP composition of multiple AP of instruction cooperation in the instruction information of the request first message of AP broadcast transmission.

It can only be that corresponding STA receives the instruction information and directly executes channel competition typically, for the instruction information for including the request first message accessed in response message.It is usually broadcast message for including the instruction information in control/management frame, all STA in control/management frame range of receiving can receive the instruction information.Receive the STA of broadcast instruction information, it is first determined AP to be cooperated executes channel competition then after determining that oneself can be communicated with each AP in AP to be cooperated.

It optionally, can also include the mark for being desire to participate in the STA of channel competition in the instruction information of the request first message of AP broadcast transmission.Receive the STA of broadcast instruction information, it is first determined whether oneself is the specified STA for being desire to participate in channel competition of AP.If it is, further determining that AP to be cooperated, then after determining that oneself can be communicated with each AP in AP to be cooperated, channel competition is executed.

Alternatively possible is to be achieved in that, AP can gather according to the communication AP that STA is reported determines that some STA can effectively service certain collaboration sets, the directly specified STA for being desire to participate in channel competition of AP.It may include the mark for being desire to participate in the STA of channel competition in the instruction information of the request first message of broadcast transmission, at this time, only corresponding STA can receive broadcast instruction information, and directly execute channel competition, the STA of successful contention to channel can will indicate that the collaboration set ID in information is added in first message, as the mark of first message, and broadcast transmission first message.Certainly, AP can also directly send the instruction information of request first message to the STA for being desire to participate in channel competition.

It is appreciated that multiple AP are before being cooperated, it is also necessary to interaction coordination information, i.e., the specific rule that cooperates.In the present embodiment, following optional embodiment is specifically provided to interact Coordination information:

As the first optional embodiment, the rule that cooperates may be embodied in the instruction information of request first message, STA judges that oneself can participate in channel competition according to the instruction information, then after successful contention to the first channel, the rule that will cooperate carries in first message, while being sent to the AP in collaboration set.Or STA can also temporarily store collaborative work rule, the AP in collaboration set is waited to send the response message of the first channel right to use, after the response message that STA receives the first channel right to use of the transmission of all AP in collaboration set, will cooperate the regular AP being sent in collaboration set immediately.The AP that can thus save in collaboration set coordinate by the first channel the expense of interaction.

It should be noted that if in collaboration set multiple AP to STA have sent request first message instruction information, and in the instruction information include cooperate rule, at this time AP can also by the priority information of oneself carry instruction information in.Collaborative work rule in the instruction information of AP transmission with highest priority can be sent to the AP of other low priorities according to the priority for the AP for sending the instruction information by STA.

As second of optional embodiment, the AP wait cooperate can interact collaborative work rule by the first channel after obtaining the right to use of the first channel of STA competition.In order to avoid multiple AP in AP to be cooperated initiate interaction request simultaneously, can be coordinated using following optional method:

A) different priority can be set to the AP for participating in cooperation, high priority AP has coordinated initiative, other AP into collaboration set send the rule that cooperates by the first channel from the AP of highest priority in collaboration set.

If the STA for b) sending first message is currently accessed in a certain AP in collaboration set, the coordinated initiative of AP tool that the STA of first message is accessed then is sent, other AP into collaboration set send the rule that cooperates to the AP accessed from the STA of transmission first message by the first channel.

C) first message that STA can also be sent by it informs the AP in collaboration set, it is the instruction information for having received which AP that it, which participates in this channel competition, such as STA1 takes the lead in competing to after channel, can be informed by first message AP1 and AP2 its to participate in this channel competition be the instruction information for having received the request first message of AP1, then AP1 just has coordinated initiative.

It is understood that in the present embodiment, suitable coordination approach can be selected according to different situations.
