Embodiment

For making object, technical scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.

A kind of flow chart that connects method for building up that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, the method for the present embodiment comprises:

Step 101, in the time that the STA of AP and associated this AP cannot direct communication, AP sends relaying probe request message at least one trunking, this detection relay request message is used to indicate trunking and sends probe message to this STA.

In the present embodiment, after STA associated AP, cannot mainly refer to that STA is after associated AP with the situation of AP direct communication, AP and STA do not hear mutually the other side within a period of time.The present embodiment does not hear mutually that take AP and STA the other side describes as example within a period of time.For example, if AP does not receive the data of this STA continuously at the time point of the multiple STA of presetting reported datas, think cannot direct communication with this STA for AP, but in network, some trunkings likely still can be heard this STA.Here the trunking in network can be the STA that possesses relay function, can be also an equipment that possesses website function and relay function, can be also an equipment that possesses access point function, website function and relay function.Wherein, AP knows in network, which equipment has relay capabilities in advance.For example, trunking can, when associated with AP, report it whether to have relay capabilities to AP, and based on reporting of trunking, AP can know in network, which equipment has relay capabilities.

Optionally, AP is after the STA that determines AP and associated this AP cannot direct communication, at least one trunking transmission relaying probe request message in network, to indicate these trunkings to this STA transmission probe message.

Optionally, a kind of execution mode that AP sends relaying probe request message at least one trunking comprises: AP sends relaying probe request message with broadcast mode at least one trunking.

Optionally, the another kind of execution mode that AP sends relaying probe request message at least one trunking comprises: AP sends relaying probe request message with multicast mode at least one trunking.

Optionally, another execution mode that AP sends relaying probe request message at least one trunking comprises: AP sends relaying probe request message with mode of unicast at least one trunking.

In this explanation, there is relay capabilities if which equipment AP only knows, but do not know the positional information of these trunkings, AP can adopt the mode of broadcast to send relaying probe request message to these trunkings.If which equipment AP not only know and have relay capabilities, and know the positional information of these trunkings, AP can send relaying probe request message to these trunkings in the mode of multicast or clean culture.For example, these link terminals, when associated with AP, not only reported and oneself have been had relay capabilities, have reported the positional information of oneself to AP simultaneously.

Optionally, a kind of mode that relaying probe request message indication trunking sends probe message to the STA of associated AP is: relaying probe request message comprises identification information and the transmission indication of the STA of associated AP.Wherein, the identification information of this STA is used for mark need to send probe message to for which STA, is used to indicate and send indication the STA transmission probe message that trunking identifies to the identification information of STA.Optionally, the mode that relaying probe request message is carried described transmission indication comprises: by certain field in relaying probe request message, carry described transmission indicate by this field; Or relaying probe request message itself just represents described transmission indication.

Further, relaying probe request message, except comprising the identification information of STA and sending indication, can also comprise transmitting time indication, number indication and send at least one in the indication of interval.

For example, the another kind of mode that relaying probe request message indication trunking sends probe message to the STA of associated AP is: relaying probe request message comprises identification information, transmission indication and the transmitting time indication of this STA; Wherein, which STA the identification information of STA need to send probe message to for mark, send indication and be used to indicate the STA that trunking identifies to the identification information of STA and send probe message, and transmitting time indication is used to indicate STA that trunking identifies to the identification information of STA and sends the time point of probe message.For example, the indication of this transmitting time can be AP be trunking arrange for send time period or at least one time point etc. of probe message to STA, trunking can send probe message to the STA of associated AP in this time period or these time points.

Again for example, another mode that relaying probe request message indication trunking sends probe message to the STA of associated AP is: relaying probe request message comprises: interval indication is indicated and sent to the identification information of STA, transmission indication, number; Wherein, which STA the identification information of STA need to send probe message to for mark, send indication and be used to indicate the STA transmission probe message that trunking identifies to the identification information of STA, number indication is used to indicate the STA that trunking identifies to the identification information of STA and sends the number of probe message, and sends interval indication and be used to indicate STA that trunking identifies to the identification information of STA and send the time interval of probe message.Based on this, trunking can indicate the STA that the indicated time interval periodically identifies to the identification information of STA to send probe message according to sending interval, indicates indicated number until total number of transmission probe message reaches described number.

Further, based on above-mentioned variety of way, AP can also carry transmitted power indication, code modulation mode indication and sending strategy indication etc. in relaying probe request message.Wherein, transmitted power indication is used to indicate the STA that trunking identifies to the identification information of STA and sends the power that probe message is used, and code modulation mode indication is used to indicate the STA that trunking identifies to the identification information of STA and sends the code modulation mode that probe message is used, sending strategy indication is used to indicate trunking and sends probe message at the STA identifying to the identification information of STA, but when the probe response message that the STA that the identification information that receives STA in failing at the appointed time identifies returns, for again sending to this STA the adjustment that probe message is made, may be for example to adjust transmitted power, code modulation mode etc.

For trunking, receiving after relaying probe request message, according to the indication of relaying probe request message, the STA identifying to the identification information of STA sends probe message, and waits for the probe response message that this STA returns for this probe message.If trunking, in the time of reception of specifying, receives the probe response message that STA returns, trunking returns to relaying to AP and surveys success message.Described probe message at least comprises identification information and the detection indication of this STA, and described detection indication is used to indicate to be surveyed this STA.Wherein, STA receives after probe message, specifically can return to probe response message according to the detection indication in this probe message.Described probe response message can comprise the identification information of STA and the identification information of trunking, and the trunking here refers to the trunking that sends the probe message corresponding with this probe response message.

Optionally, if trunking is in the time of reception of specifying, do not receive the probe response message that STA returns, trunking can return to relaying to AP and survey failed message.Or, if trunking is in the time of reception of specifying, not receiving the probe response message that STA returns, trunking can not send any message to AP.

In this explanation, because 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, for example reduce the time of probe message busy channel, probe message can be less, and for example probe message can be without packet (Null Data Packet, referred to as NDP) Frame of type, but be not limited to this.

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

Probe response message can be existing probe request in standard (Probe Request Frame), but is not limited to this.

Step 102, AP receive the relaying that the first trunking at least one trunking returns and survey success message, the transmission after receiving the probe response message that probe message that STA sends for the first trunking returns that is the first trunking that this relaying is surveyed success message.

AP is sending after relaying probe request message, can in the time of reception of specifying, receive the relaying detection success message that trunking returns.Because not all trunking can detect this STA, so AP may can only receive the relaying detection success message that part trunking returns.For ease of distinguishing, the trunking that returns to relaying detection success message to AP is called the first trunking by the present embodiment.

Based on this, AP, after at least one trunking sends relaying probe request message, receives the relaying detection success message that the first trunking at least one trunking sends.

Optionally, AP can also receive the relaying that at least one trunking, other trunkings except the first trunking send and survey failed message.

Optionally, the probe response message that STA returns can be relay request message, or ACK determines message etc.

In this explanation, it can be existing probing response frame in standard (ProbeResponse Frame) that relaying is surveyed success message, but is not limited to this.

Step 103, AP establish a communications link by the first trunking and STA.

AP surveys after success message at the relaying that receives the first trunking transmission, establishes a communications link by the first trunking and STA.

In the present embodiment, AP initiatively requires part or all of trunking to remove to survey the STA associated with AP, and whether return to relaying according to these trunkings and survey success message, therefrom determine the trunking that relay services can be provided for this STA, AP can provide the trunking of relay services and STA to communicate by these like this, in the time that the STA of AP and associated this AP cannot direct communication, AP can re-establish communication connection as early as possible by definite trunking and this STA, rather than simply abandon this STA, avoid causing the loss of significant data.

In an optional execution mode, the process that AP establishes a communications link by the first trunking and STA comprises: if the first trunking is multiple, AP selects one as target trunking from multiple the first trunkings, send relaying Indication message to target trunking, to indicate this target trunking as AP and STA provide relay services, then establish a communications link by target trunking and this STA.Wherein, target trunking refers to the trunking that relay services is provided for AP and STA.

If the first trunking only has one, AP can directly determine that this first trunking is target trunking, sends relaying Indication message to this target trunking, then establishes a communications link by this target trunking and this STA.

In this embodiment, by AP select target trunking from the first trunking, and make this trunking know that oneself is target trunking, is responsible for communicating by letter between AP and STA and carries out relaying by send relaying Indication message to target trunking.

Based on above-mentioned, a kind of mode of AP select target trunking from multiple the first trunkings comprises: the multiple relayings that AP sends according to multiple the first trunkings that receive are surveyed signal strength signal intensity, signal power and/or the signal to noise ratio etc. (being at least one among signal strength signal intensity, signal power and signal to noise ratio etc.) of success messages, therefrom selects first trunking of signal quality best (as the strongest in signal strength signal intensity, signal power is maximum and/or signal to noise ratio is the most high) as target trunking.Or AP also can select one as target trunking at random from multiple the first trunkings.This execution mode is specifically by AP select target trunking.

The another kind of mode of AP select target trunking from multiple the first trunkings comprises: multiple relayings that AP sends from multiple the first trunkings that receive are surveyed success message, obtain the first relaying detection success message that comprises that relay request identifies, this relay request mark is that the first trunking that sends the first relaying detection success message is encapsulated in the first relaying detection success message in the time meeting default first condition; Then, AP surveys the first trunking that success message is corresponding and selects one as target trunking from the first relaying.Optionally, be one if the first relaying is surveyed success message, AP can directly determine that the first trunking that sends this first relaying detection success message is as target trunking; Be multiple if the first relaying is surveyed success message, AP can therefrom select first relaying to survey success message at random, using the first trunking that sends selected the first relaying detection success message as target trunking.Or, AP can survey according to multiple the first relayings signal strength signal intensity, signal power and/or the signal to noise ratio etc. of success message, therefrom select the first best relaying of signal quality to survey success message, using the first trunking that sends selected the first relaying detection success message as target trunking, etc.

Above-mentioned first condition can comprise following its combination of arbitrary conditioned disjunction:

The number of the STA that described the first trunking is served as target trunking is less than default number thresholding;

Link-quality between described the first trunking and described AP is better than default link-quality.This link-quality is predefined, can be the various parameter values that are used for weighing link-quality, and in the present embodiment, default link-quality is mainly as the standard of weighing the link-quality between the first trunking and AP.

The process of above-mentioned execution mode is specially: the first trunking that receives the probe response message that STA returns for probe message, judge whether to meet default first condition, if judged result is yes, meet default first condition, the first trunking is surveyed in success message and is encapsulated relay request mark at relaying, for identifying this first trunking request as target trunking; AP receives the relaying of the first trunking transmission and surveys after success message, the relaying that comprises relay request mark from sending is surveyed select target trunking the first trunking of success message (i.e. the first relaying detection success message), then establishes a communications link by target trunking and this STA.This execution mode is also finally by AP select target trunking.

Optionally, if judged result is no, do not meet default first condition, the first trunking is directly surveyed success message by relaying and is sent to AP, and in this case, relaying is surveyed in success message and do not comprised that relay request identifies.

Another mode of AP select target trunking from multiple the first trunkings comprises: multiple relayings that AP sends from multiple the first trunkings are surveyed success message, obtains the second relaying detection success message that comprises relaying indication; Described relaying indication is to send the first trunking of the second relaying detection success message from probe response message, to obtain and be encapsulated in the second relaying detection success message, and described relaying indication selects the first trunking of transmission the second relaying detection success message as target trunking for identifying this STA; Then, AP determines that it is target trunking that the second relaying is surveyed the first trunking corresponding to success message.Wherein, the second relaying is surveyed the first trunking that the first trunking corresponding to success message is this second relaying detection success message of transmission.

The process of aforesaid way is specially: STA receives after the probe message of the first trunking transmission at least one trunking, according to the relevant information of probe message, received signal strength or the received power etc. of such as probe message, select a probe message, and determine that the first trunking that sends selected probe message is as target trunking, encapsulation (can be regarded as and carry) relaying indication in the probe response message of returning to this first trunking, selects this first trunking as target trunking to indicate; This first trunking receives after probe response message, the relaying indication in probe response message is encapsulated in to relaying and surveys in success message, then sends to AP; For other the first trunkings, STA can return to the probe response message of not carrying relaying indication, and other trunkings also can return to the relaying detection success message that does not carry relaying indication to AP.Based on this, AP surveys success message from the relaying receiving, and selection comprises the relaying detection success message (the second relaying is surveyed success message) of relaying indication, and using the first trunking that sends the second relaying detection success message as target trunking.In this embodiment, target trunking is specifically determined by STA.

In this explanation, in the mode of above-mentioned each definite target trunking, the probe response message that STA sends can also comprise some information relevant to STA, battery electric quantity, positional information etc. that such as STA is current.Optionally, the first trunking can be crossed information exchange relevant with STA in probe response message relaying detection success message and report AP.

In this explanation, the process of above-mentioned definite target trunking, is all to survey according to the indication of AP at trunking in the process of STA to carry out, but is not limited to this.For example, determine that the process of target trunking can be carried out after completing the detection of STA, survey the process of STA and the process of definite target trunking can be separate.For the independent process (assigning process referred to as target trunking) of determining target trunking, illustrate below:

Optionally, after completing the detection of STA, be after AP receives the relaying detection success message of each the first trunking transmission, STA can determine target trunking from the first trunking of transmission probe message, then send relaying notice message to the first trunking as target trunking, inform that this first trunking is as target trunking on the one hand, make on the other hand this first trunking send relaying notice message to AP, make AP know that this first trunking is target trunking; Based on this, the first trunking that is chosen as target trunking by STA sends relaying notice message to AP; AP receives after relaying notice message, determines that the first trunking that sends relaying notice message is as target trunking.

Optionally, after completing the detection of STA, be after AP receives the relaying detection success message of each the first trunking transmission, AP can determine target trunking from the first trunking of transmission relaying detection success message, then can send relaying notice message to each the first trunking, this relaying notice message can comprise the identification information as the first trunking of target trunking, which the first trunking notices target trunking is on the one hand, make on the other hand this target trunking send relaying notice message to STA, make STA know that this first trunking is target trunking, or, AP also can only send relaying notice message to this first trunking that is selected as target trunking, notice it and be used as target trunking, based on this, the first trunking that is chosen as target trunking by AP sends relaying notice message to STA, STA receives after relaying notice message, determines that the first trunking that sends relaying notice message is as target trunking.

From above-mentioned, in above-mentioned target trunking appointment process, STA and AP all can be used as arbitrator and determine which the first trunking is as target trunking.Except aforesaid way, can also there be other modes, do not repeat them here.

Based on the mode of above-mentioned various definite target trunkings, AP can also comprise after establishing a communications link by target trunking and STA:

The second encrypting messages that AP receiving target trunking sends, described the second encrypting messages is that described target trunking uses the second key between described AP and described target trunking to be encrypted acquisition to the first encrypting messages, and described the first encrypting messages is that STA uses the first key between STA and AP to be encrypted acquisition to cipher key acquisition request.

Then, AP is that STA and target trunking distribute the 3rd key according to cipher key acquisition request, and uses the second key to be encrypted the 3rd key, obtains the 3rd encrypting messages, uses the first key to be encrypted and to obtain the 4th encrypting messages the 3rd key.Concrete, AP receives after the second encrypting messages, can use successively the second key and the first key to resolve, obtain cipher key acquisition request, then be that STA and target trunking distribute the 3rd key according to cipher key acquisition request, and use respectively the first key and the second key to be encrypted the 3rd key, obtain the 4th encrypting messages and the 3rd encrypting messages.
