Specific implementation mode

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art The every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.

Fig. 1 is a kind of flow chart of connection method for building up provided in an embodiment of the present invention.As shown in Figure 1, the present embodiment Method includes：

Step 101, when AP be associated with the AP STA can not direct communication when, AP at least one trunking send in After probe request message, which is used to indicate trunking and sends probe message to the STA.

In the present embodiment, after STA associated APs, STA can not be primarily referred to as in associated AP with the case where AP direct communications Later, AP and STA does not hear mutually other side whithin a period of time.The present embodiment is listened mutually not whithin a period of time with AP and STA See for other side and illustrates.For example, if AP does not continuously receive this at multiple time points for presetting STA reported datas The data of STA, then AP think with the STA can not direct communication, but some trunkings are possible to still to hear in network The STA.Here the trunking in network can be the STA for having relay function, can also be one have website function and The equipment of relay function, can also be one have access point function, website function and relay function equipment.Wherein, AP is pre- First know which equipment has relay capabilities in network.For example, whether trunking can report it when being associated with AP to AP With relay capabilities, reporting based on trunking, AP can know which equipment has relay capabilities in network.

Optionally, AP is determining that AP can not be after direct communication with the STA for being associated with the AP, at least one relaying into network Equipment sends relaying probe request message, to indicate that these trunkings send probe message to the STA.

Optionally, AP includes to a kind of embodiment of at least one trunking transmission relaying probe request message：AP With broadcast mode relaying probe request message is sent at least one trunking.

Optionally, AP includes to the another embodiment of at least one trunking transmission relaying probe request message： AP sends relaying probe request message with multicast mode at least one trunking.

Optionally, AP includes to another embodiment of at least one trunking transmission relaying probe request message： AP sends relaying probe request message with mode of unicast at least one trunking.

Illustrate herein, if AP just knows which equipment has relay capabilities, but does not know the position of these trunkings Information, then AP the mode of broadcast may be used and send relaying probe request message to these trunkings.If AP is not just known that Which equipment has relay capabilities, and knows the location information of these trunkings, then AP can be with multicast or the side of unicast Formula sends relaying probe request message to these trunkings.For example, these link terminals are not only reported when being associated with AP Oneself has relay capabilities, while the location information of oneself is reported to AP.

Optionally, relaying probe request message indicates that trunking sends a kind of side of probe message to the STA of associated AP Formula is：Relaying probe request message includes that the identification information of the STA of associated AP and transmission indicate.Wherein, the identification information of the STA Need which STA to send probe message to for identifying, and sends instruction and be used to indicate identification information institute of the trunking to STA The STA of mark sends probe message.Optionally, relaying probe request message carry it is described send instruction mode include：Pass through The certain field in probe request message is relayed, the transmission instruction is carried with the field；Alternatively, relaying probe request message Itself mean that the transmission instruction.

Further, relaying probe request message can also include other than the identification information including STA is with transmission instruction At least one of sending time instruction, number instruction and the instruction of transmission interval.

For example, relaying probe request message indicates that trunking sends the another kind side of probe message to the STA of associated AP Formula is：Relaying probe request message includes the identification information of the STA, sends instruction and sending time instruction；Wherein, the mark of STA Know information and need which STA to send probe message to for mark, sends instruction and be used to indicate trunking to the mark of STA letter The identified STA of breath sends probe message, and sending time instruction is used to indicate trunking and is identified to the identification information of STA STA send probe message time point.For example, the sending time instruction can be AP be trunking arrangement for STA sends the period of probe message or at least one time point etc., and trunking can be in the period or these times Point sends probe message to the STA of associated AP.

In another example relaying probe request message indicates that trunking sends another of probe message to the STA of associated AP Mode is：Relaying probe request message includes：The identification information of STA sends instruction, number instruction and sends interval instruction；Its In, the identification information of STA needs which STA to send probe message to for identifying, send instruction be used to indicate trunking to The STA that the identification information of STA is identified sends probe message, and number instruction is used to indicate identification information of the trunking to STA The STA identified sends the number of probe message, and sends interval instruction and be used to indicate identification information institute of the trunking to STA The STA of mark sends the time interval of probe message.Based on this, trunking can according to send interval instruction it is indicated when Between the STA that are identified to the identification information of STA of gap periods send probe message, the total number until sending probe message Until reaching the indicated number of the number instruction.

Further, be based on above-mentioned various modes, AP can also be carried in relay probe request message transmission power indicate, Code modulation mode indicates and sending strategy indicates etc..Wherein, transmission power instruction is used to indicate mark of the trunking to STA The STA that information is identified sends the power that probe message uses, and code modulation mode instruction is used to indicate trunking to STA The STA that is identified of identification information send the code modulation mode that probe message uses, sending strategy instruction is used to indicate relaying Equipment sends probe message in the STA identified to the identification information of STA, but is the failure within a specified time receive STA's When the probe response message that the STA that identification information is identified is returned, to send the adjustment that probe message is made to the STA again, For instance it can be possible that adjustment transmission power, code modulation mode etc..

For trunking, after receiving relaying probe request message, according to the finger of relaying probe request message Show, the STA identified to the identification information of STA sends probe message, and the STA is waited for be directed to the detection that the probe message returns Response message.If trunking in specified receiving time, receives the probe response message of STA returns, then relaying is set It is standby to return to relaying detection success message to AP.The probe message is indicated including at least the identification information of the STA and detection, described Detection instruction, which is used to indicate, detects the STA.Wherein, after STA receives probe message, can specifically be disappeared according to the detection Detection instruction in breath returns to probe response message.The probe response message may include that the identification information of STA and relaying are set Standby identification information, trunking here refers to the trunking for sending probe message corresponding with the probe response message.

Optionally, if trunking is in specified receiving time, the probe response message of STA returns is not received, Then trunking can return to relaying detection failed message to AP.Alternatively, if trunking in specified receiving time, not The probe response message of STA returns is received, trunking can not send any message to AP.

Illustrate herein, since the quantity of trunking may be more, so the quantity of the probe message of channel May be more, in order to save channel resource, such as reduce the time of probe message busy channel, probe message can be smaller, Such as probe message can be no data packet（Null Data Packet, referred to as NDP）The data frame of type, but be not limited to This.

Probe message can also be the beacon frame of trunking broadcast（Beacon）, but not limited to this.

Probe response message can be existing probe request in standard（Probe Request Frame）, but it is unlimited In this.

Step 102, AP receive the relaying detection success message of the return of the first trunking at least one trunking, Relaying detection success message is the first trunking in the probe message return for receiving STA for the transmission of the first trunking Probe response message after send.

AP can receive the relaying that trunking returns after sending relaying probe request message in specified receiving time Detect success message.Since not all trunking can detect the STA, so AP may can only be received in part Success message is detected after the relaying that equipment returns.For ease of distinguishing, the present embodiment will return to relaying detection success message to AP Trunking is known as the first trunking.

Based on this, AP at least one trunking after sending relaying probe request message, during reception is at least one Success message is detected after the relaying that the first trunking in equipment is sent.

Optionally, AP can also receive other trunkings in addition to the first trunking at least one trunking The relaying of transmission detects failed message.

Optionally, the probe response message that STA is returned can be that relay request message or ACK determine message etc..

Illustrate herein, relaying detection success message can be existing probing response frame in standard（ProbeResponse Frame）, but not limited to this.

Step 103, AP are established by the first trunking and STA and are communicated to connect.

AP passes through the first trunking and STA after receiving the relaying detection success message of the first trunking transmission Establish communication connection.

In the present embodiment, the part or all of trunking of AP initiatives removes detection and the associated STA of AP, and according to this Whether a little trunkings return to relaying detection success message, are therefrom determined to provide the trunking of relay services for the STA, The trunking that AP in this way can be capable of providing relay services by these is communicated with STA, as AP and the STA for being associated with the AP Can not direct communication when, AP can re-establish communication connection as early as possible by determining trunking and the STA, rather than simply The STA is abandoned, the loss for causing significant data is avoided.

In an optional embodiment, the process that AP establishes communication connection by the first trunking with STA includes：If First trunking is multiple, and AP selects one as object relay equipment, to object relay from multiple first trunkings Equipment sends relaying instruction message, to indicate that the object relay equipment provides relay services for AP and STA, then by target It establishes and communicates to connect after equipment and the STA.Wherein, object relay equipment refers to providing the relayings of relay services for AP and STA to set It is standby.

If there are one the first trunkings, AP can directly determine that first trunking sets for object relay It is standby, relaying instruction message is sent to the object relay equipment, communication link is then established by the object relay equipment and the STA It connects.

In this embodiment, by AP from the first trunking selection target trunking, and by object relay Equipment sends relaying instruction message and the trunking is made to know that oneself is object relay equipment, is responsible between AP and STA Communication is relayed.

Based on above-mentioned, a kind of AP modes of selection target trunking from multiple first trunkings include：AP according to Signal strength, signal power and/or the letter for multiple relayings detection success message that multiple first trunkings received are sent Make an uproar than etc.（I.e. signal strength, signal power and signal-to-noise ratio etc. at least one of）, therefrom selection signal is best in quality（Such as Signal strength is most strong, signal power is maximum and/or signal-to-noise ratio is most high）First trunking set as object relay It is standby.Alternatively, AP can also randomly choose one from multiple first trunkings is used as object relay equipment.The embodiment has Body is by AP selection target trunkings.

AP another ways of selection target trunking from multiple first trunkings include：AP is more from what is received In multiple relayings detection success message that a first trunking is sent, acquisition includes the first relaying detection of relay request mark Success message, relay request mark are to send the first trunking of the first relaying detection success message to meet preset the It is encapsulated into when one condition in the first relaying detection success message；Then, AP is from the first relaying detection success message corresponding the Selected in one trunking one as object relay equipment.Optionally, if the first relaying detection success message is one, AP can directly determine the first trunking for sending the first relaying detection success message as object relay equipment；If the One relaying detection success message is multiple, then AP can therefrom randomly choose one first relaying detection success message, will send First trunking of selected first relaying detection success message is as object relay equipment.Alternatively, AP can be according to more Signal strength, signal power and/or the signal-to-noise ratio etc. of a first relaying detection success message, therefrom selection signal is top-quality First relaying detection success message will send the first trunking of selected first relaying detection success message as target Trunking, etc..

Above-mentioned first condition may include following either condition or combinations thereof：

The number for the STA that first trunking is serviced as object relay equipment is less than predetermined number thresholding；

Link-quality between first trunking and the AP is better than preset link-quality.The link-quality is It is preset, can be the various parameter values for being used for weighing link-quality, in the present embodiment, preset link-quality is main As the standard for weighing the link-quality between the first trunking and AP.

The process of the above embodiment is specially：Receive the of the probe response message that STA is returned for probe message One trunking judges whether to meet preset first condition, if it is judged that being yes, that is, meets preset first condition, Then the first trunking encapsulation relay request mark in relaying detects success message, for identifying first trunking request As object relay equipment；Include relaying from sending after AP receives the relaying detection success message of the first trunking transmission The relaying of request mark detects success message（I.e. first relaying detection success message）The first trunking in selection target After equipment, is then established and communicated to connect by object relay equipment and the STA.The embodiment is also finally by AP selection targets Trunking.

Optionally, if it is judged that being no, that is, be unsatisfactory for preset first condition, then the first trunking directly will in It is sent to AP after detection success message, does not include in this case, in relaying detection success message that relay request identifies.

AP another mode of selection target trunking from multiple first trunkings includes：AP is from multiple first Include the second relaying detection success message for relaying instruction after in multiple relayings detection success message that equipment is sent, obtaining；Institute It is to send the first trunking that second relays detection success message to obtain and encapsulate from probe response message to state relaying instruction Into the second relaying detection success message, the relaying instruction detects successfully for identifying STA selections the second relaying of transmission First trunking of message is as object relay equipment；Then, AP determines that the second relaying detects success message corresponding first Trunking is object relay equipment.Wherein, the second corresponding first trunking of relaying detection success message be send this First trunking of two relaying detection success messages.

The process of aforesaid way is specially：STA receives the spy of the transmission of the first trunking at least one trunking After surveying message, according to the relevant information of probe message, such as the received signal strength of probe message or reception power etc., one is selected A probe message, and determine and send the first trunking of selected probe message as object relay equipment, to this It is encapsulated in the probe response message that one trunking returns（It can be regarded as carrying）Relaying instruction, with instruction selection first relaying Equipment is as object relay equipment；After first trunking receives probe response message, in probe response message It is encapsulated in relaying detection success message after instruction, is then sent to AP；For other the first trunkings, STA can be returned The probe response message of relaying instruction is not carried, other trunkings can also return to the relaying for not carrying and relaying and indicating to AP and visit Survey success message.Based on this, AP from receive relaying detection success message in, selection include relaying instruction relaying detect at Work(message（I.e. second relaying detection success message）, and using send second relaying detection success message the first trunking as Object relay equipment.In this embodiment, object relay equipment is specifically to be determined by STA.

Illustrate herein, in the mode of above-mentioned each determining object relay equipment, the probe response message that STA is sent can be with Including with some relevant information of STA, such as battery capacity, location information etc. that STA is current.Optionally, the first trunking Information related with STA in probe response message can be detected success message by relaying and be reported to AP.

Illustrate herein, the process of above-mentioned determining object relay equipment, is all that STA is detected according to the instruction of AP in trunking During carry out, but it is not limited to this.For example, determining that the process of object relay equipment can complete the detection to STA It carries out later, that is, the process for detecting STA can be mutual indepedent with the process for determining object relay equipment.For being independently determined target The process of trunking（Referred to as object relay device assignment process）, it is exemplified below：

Optionally, after completing to the detection of STA, i.e. AP receive relaying detection that each first trunking is sent at After work(message, STA can determine object relay equipment from the first trunking for sending probe message, then to as mesh The first trunking for marking trunking sends relaying notice message, on the one hand informs first trunking as object relay On the other hand equipment makes first trunking send relaying notice message to AP, AP is made to know that first trunking is mesh Mark trunking；Based on this, the first trunking that object relay equipment is selected as by STA sends relaying notice message to AP； After AP receives relaying notice message, determine the first trunking for sending relaying notice message as object relay equipment.

Optionally, after completing to the detection of STA, i.e. AP receive relaying detection that each first trunking is sent at After work(message, AP can determine object relay equipment from sending to relay in the first trunking for detecting success message, then Relaying notice message can be sent to each first trunking, which may include as object relay equipment The identification information of first trunking, which the first trunking on the one hand notices object relay equipment is, is on the other hand made The object relay equipment sends relaying notice message to STA, and STA is made to know that first trunking is object relay equipment, or Person, the first trunking that AP can also only be selected as object relay equipment to this send relaying notice message, notice its quilt As object relay equipment；Based on this, the first trunking that object relay equipment is selected as by AP sends relaying notice to STA Message；After STA receives relaying notice message, determine that the first trunking for sending relaying notice message is set as object relay It is standby.

From the foregoing, it can be seen that during above-mentioned object relay device assignment, STA and AP can be used as which arbitrator determines A first trunking is as object relay equipment.In addition to aforesaid way, there can also be other modes, details are not described herein.

Based on the mode of above-mentioned various determining object relay equipment, AP establishes communication link by object relay equipment and STA Can also include after connecing：

AP receives the second encryption message that object relay equipment is sent, and the second encryption message is that the object relay is set Acquisition is encrypted in standby the second key pair first encryption message using between the AP and the object relay equipment, described First encryption message is that acquisition is encrypted to cipher key acquisition request using the first key between STA and AP in STA.
