Technical field

The present invention relates to wireless communication field, awakening method and equipment, the identity configuration method of aided wake interface and equipment of espespecially a kind of communication interface.

Background technique

Internet of Things (IoT) standard of 802.11 normal structure plan of IEEE based on Wi-Fi, target are that Wi-Fi technology is promoted the use of to internet of things field, including wearable electronic and digital Medical Devices.As the main power consumption module of IoT equipment and wearable electronic, the power consumption of existing Wi-Fi module is too big, is not directly applicable wearable electronic.This is because IoT equipment and wearable electronic, for example, motion bracelet, smartwatch and digital Medical Devices etc., general small volume, the volume and capacity for the battery that can be carried are all very limited, and wearable electronic is relatively high to requiring the cruise duration of battery.In order to which Wi-Fi technology to be applied in internet of things field and wearable electronic, the power consumption improved and reduce the Wi-Fi communication technology is necessary.

In the Wi-Fi communication technology, equipment (STA) idle listening (idle listening) channel can waste a large amount of electric energy.In order to reduce energy dissipation caused by equipment idle listening channel, Wi-Fi technology introduces dormancy mechanism, i.e. the Wi-Fi module (Wi-Fi interface) of equipment enters suspend mode in the case where no data are transmitted and closes receiver/transmitter.Traditional Wi-Fi dormancy mechanism can reduce the power consumption of Wi-Fi module.However, if the Wi-Fi module of a STA in a dormant state, access point (AP) cannot send data to the STA, and AP need to wait until that the Wi-Fi module of the STA is waken up.It thus will increase communication delay, can not realize on-demand (On-Demand) real-time Data Transmission.In order to reduce traditional Wi-Fi dormancy mechanism bring communication delay, STA would generally follow certain suspend mode, periodically wake up and check that AP has no data to need to be transferred to the STA.The dormancy time ratio for reducing STA again in this way, increases the energy consumption of STA.

To solve the above-mentioned problems, 802.11 normal structure of IEEE is most recently newly to have set up a group, study wake on wireless electricity/receiver (Wake-up Radio/Receiver of super low-power consumption, WUR) the standard of technology and formulation based on WUR, it is desirable to reduce the average power consumption of the Wi-Fi module in equipment by wake on wireless electricity/receiver, while on-demand (On-Demand) real-time Data Transmission may be implemented.

The wake on wireless electricity of auxiliary/receiver (WUR) is an increased ultra-low power consumption wireless interface on the wireless device, is existed simultaneously with the principal communication module (for example, Wi-Fi module) of wireless device.When not having message to need to receive or transmit, the principal communication module (for example, Wi-Fi module) of equipment enters deep-sleep, and opens WUR module progress super low-power consumption and listen to.

As shown in Figure 1, wirelessly being set when the second wireless device (wake-up device, for example, AP) has message to need to be transferred to first When standby (equipment being waken up, for example, STA), the second wireless device first sends wake-up association (Wake-up Packet, WUP) to the WUR interface of the first wireless device.After the auxiliary WUR module of first wireless device receives wake-up association, checks the recipient address of the wake-up association and confirm the correctness and authenticity of the wake-up association.If the address of the WUR of the first wireless device described in the target receiver address matching that the wake-up association carries, and the wake-up association is correct, true, the WUR of first wireless device can send wake-up signal to the Wi-Fi module of first wireless device, to wake up the first wireless device principal communication module (for example, 802.11 modules).After having sent wake-up signal, the WUR module of first wireless device can enter deep sleep state.

Due to using particularly simple circuit design and signal processing method, the average energy consumption of WUR module is very low, for example, when using working cycles (Duty-Cycling), the average power consumption of WUR is about 100 μ W, probably there was only the 0.1% of Wi-Fi average power consumption.Channel is listened to compared to direct Wi-Fi module of opening, wireless device average power consumption can be significantly reduced using WUR.

The application in order to facilitate understanding, the Key Term that may be used the technical solution of the application first are illustrated, table 1 as described below.

Table 1

As shown in Figure 1, wireless device has increased ultra-low power consumption wireless interface (such as WUR module) newly, which can wake up the principal communication module in deep sleep state after receiving wake-up association in order to reduce the power consumption of principal communication module.

For wireless device, the reception and decoding of wake-up association are simple more many than the Wi-Fi frame of standard.Wake-up association generallys use the modulation system for being easy to receiving end demodulation, such as OOK (On-Off Keying) modulation.By taking OOK is modulated as an example, receiving end is by there is noenergy judgement to receive the information of signaling bearer, for example, having energy is " 1 ", noenergy is " 0 ".And for the Wi-Fi frame of standard, need to carry out the operation such as BCC/LDPC and IFFT in transmitting terminal, a large amount of electric energy can be expended by needing to be implemented sophisticated signals processing operation, these operations such as FFT and BCC/LDPC decoding in receiving end accordingly.

In order to reduce WUR energy consumption and reduce the probability of wake-up association error, wake-up association should be short as far as possible, and carrying content should lack as far as possible.

See Fig. 2, it illustrates a kind of possible structures of wake-up association.As shown in Fig. 2, wake-up association, which includes at least, wakes up leading (Wake-up Preamble) and recipient address (Receive Address, RA).Wherein, leading (Wake-up Preamble) is waken up for sign synchronization and AGC (Automatic Gain Control, automatic growth control) setting etc..The reception Person address (Receive Address, RA) can be used for identifying the target receiver of wake-up association.The recipient address (Receive Address, RA) may include network identity (Network ID) and wake on wireless electricity mark (WUR ID).Reception address (Receive Address) can be the combination of network identity (Network ID) and wake on wireless electricity mark (WUR ID) or the reception address (Receive Address) can be wake on wireless electricity mark (WUR ID).The wake on wireless electricity mark (WUR ID) is the mark of target WUR, can be selected and be distributed by AP.The network identity (Network ID) can be used for identifying the information of (BSS) and AP of basic service set belonging to the wake-up association, for example, BSS color or BSSID, or the BSSID of compression, or compression AP MAC Address.The network identity (Network ID) can be a part of the wake on wireless electricity mark (WUR ID).

The wake-up association can further include 802.11 leading (Legacy 802.11Preamble) of tradition, and/or control information (Control Info) and/or Frame Check Sequence (FCS).Wherein, 802.11 leading (Legacy 802.11Preamble) of tradition partially can be used for backward compatibility, and traditional Wi-Fi equipment is enabled to judge present frame accordingly for Wi-Fi frame, to select corresponding channel sense decision threshold and back off time.Because WUR does not need to receive the leading part of tradition 802.11, the considerations of for efficiency of transmission, the leading of tradition 802.11 can also be not added in wake-up association.Control information (Control Info) can serve to indicate that the frame type and other information of wake-up association, for example, control command, is option.The correctness and/or authenticity for the content that the Frame Check Sequence (FCS) can be used for that recipient is helped to verify received wake-up association, i.e. the content of the received wake-up association of inspection is in transmission process either with or without error, and/or the authenticity of the inspection wake-up association.The considerations of for efficiency of transmission, wake-up association can not also include Frame Check Sequence.

It can be seen from the above, wake-up association is only successfully transmitted to wake on wireless electricity, it just can guarantee that wake on wireless electricity wakes up principal communication module.However, wake-up association may malfunction in transmission process, in order to improve the reliability of wake-up association transmission, the sending method of following two wake-up association is mainly used in the prior art.

First is that, use Direct Sequence Spread Spectrum (Direct Sequence Spread Spectrum, DSSS) technology, however sampling and quantization of the technical requirements wake on wireless electricity WUR when receiving wake-up association to signal progress upper frequency is received, and sample frequency is much higher than the data rate of wake-up association, accordingly, it is possible to which the power consumption that wake on wireless electricity WUR is received and handled wake-up association can be dramatically increased.

Second is that, use channel coding (channel coding) technology, such as Binary Convolutional Code (BCC), although, this method can correct the bit-errors that wake-up association occurs in transmission process, but channel coding requirements wake on wireless electricity WUR carries out channel decoding operation when receiving wake-up association, therefore, can equally dramatically increase the power consumption that wake on wireless electricity WUR is received and handled wake-up association.

In conclusion bit-errors can occur in transmission process for wake-up association, especially if mistake partially occurs in transmission process for wake on wireless electricity mark (WUR ID), it be easy to cause the other equipment of false wake-up or calls out not eye-catching marking device.Traditional power consumption that wake on wireless electricity WUR can be dramatically increased using channel coding and using the transmission mode of Direct Sequence Spread Spectrum.The application mainly solves how to correct the bit-errors that wake on wireless electricity mark (WUR ID) occurs in transmission process, without obviously increasing the power consumption of WUR.

In this application, AP obtains the wake on wireless electricity mark (WUR ID) of an associated STA, and determines distance parameter r.The distance parameter r can refer to that the wake on wireless electricity that receiving end can at most correct identifies the number of bit errors occurred in transmission process in scheme provided in an embodiment of the present invention, and whether the target receiver that the distance parameter r can be used for that the STA is helped to judge received wake-up association is the STA.The AP sends the wake on wireless electricity mark and apart from ginseng Number r give the STA.The first wireless interface identification of target (target receiver for being used to indicate the wake-up association) carried in the wake-up association that the AP is sent to the STA, and first wireless interface identification of target is less than or equal to the distance parameter r at a distance from the wake on wireless electricity mark of the STA.When the STA is when receiving wake-up association (WUP), if the target wake on wireless electricity mark carried in the wake-up association with less than or equal to distance parameter r, STA if, determines that the target receiver of the wake-up association is the STA at a distance from the wake on wireless electricity of STA mark.As it can be seen that the STA can judge whether the corresponding wake-up object of the wake-up association received is itself, and the power of consuming is smaller by comparing the distance between two radio identities.

The wake on wireless electricity mark of a STA in the same basic service set (BSS) malfunctions in transmission process and becomes the wake on wireless electricity mark of another STA in order to prevent, to influence the correctness for the error-correction operation that receiving end identifies wake on wireless electricity, the AP needs to guarantee that the distance between wake on wireless electricity mark of any two difference STA in the same basic service set (BSS) is greater than or is equal to (2r+1).

Specifically, see Fig. 3, it illustrates a kind of processes of wireless device awakening method provided by the present application.As shown in figure 3, the process specifically includes following steps S301~305.

S301:AP obtains the wake on wireless electricity mark (WUR ID) and distance parameter r of a STA.

Wherein, in a specific example, the AP can obtain the wake on wireless electricity mark (WUR ID) of the STA from a server and distance parameter r, the server can be Wi-Fi access controller (Wi-Fi Access Controller).In another specific example, the AP determines that the AP at most may associated STA quantity.The AP selects a wake on wireless electricity identification list (WUR ID List) according to the at most possible associated STA quantity of the AP from one or more wake on wireless electricity identification lists of storage；The AP can select a wake on wireless electricity mark (WUR ID) to identify (WUR ID) as the wake on wireless electricity of the STA from the selected wake on wireless electricity identification list (WUR ID List)；The AP can identify (WUR ID) according to the selected wake on wireless electricity and determine distance parameter r.In another specific example, the AP can be generated a wake on wireless electricity mark (WUR ID) as the wake on wireless electricity of the STA and identify (WUR ID), and is identified according to the wake on wireless electricity of the generation and determine distance parameter r.Wherein, for ease of description, distance parameter r is referred to as error correction distance.

It should be noted that in three above specific example, the target receiver for the wake-up association that the distance parameter r can be used for that the STA judgement is helped to receive.In addition, the AP needs to guarantee that the distance between the wake on wireless electricity mark of the STA and the wake on wireless electricity mark of other STA in the same basic service set (BSS) are greater than or are equal to (2r+1).

S302:AP sends the wake on wireless electricity mark (WUR ID) and distance parameter r to the STA.

Wherein, the wake on wireless electricity mark (WUR ID) and distance parameter r can be sent together, can also be sent respectively.

S303:STA receives the wake on wireless electricity mark and distance parameter r, and the wake on wireless electricity of oneself mark and distance parameter r are respectively set to the wake on wireless electricity received mark and distance parameter r.

It should be noted that the wake on wireless electricity mark and distance parameter r of setting can be used for the comparison of step S305.

S304:AP generates and sends wake-up association to the STA.

Wherein, target wake on wireless electricity mark is carried in the wake-up association, and it is necessary to meet following condition for target wake on wireless electricity mark, i.e., is less than or equal to above-mentioned distance parameter r at a distance from the wake on wireless electricity of STA mark.It should be noted that target wake on wireless electricity mark is referred to as the mark of target aided wake interface, the equipment that wake-up association intends to wake up is properly termed as target device, and wake-up association is used for the principal communication interface of wake up target equipment.Target device may be the STA, It is also likely to be other STA being connected with the AP.

Target aided wake interface identifier may include WUR ID, the address WUR, any one or more combinations in network identity.Wherein, network identity may include BSS color (basic service set color, or identify for base server) or BSSID, or the BSSID of compression, or compression AP MAC Address.

When S305:STA receives wake-up association (WUP), the target wake on wireless electricity mark carried in the wake-up association received described in STA calculating is at a distance from the wake on wireless electricity mark of the STA；Compare the relationship between the distance of calculating and distance parameter r, and acting as a result, executing corresponding processing according to calculating.

Specifically, if the distance of the calculating is less than or equal to the distance parameter r, STA if, determines that the target receiver of the wake-up association is the STA, then the STA continues to and handle the wake-up association；If the distance of the calculating is greater than the distance parameter r, STA if, determines that the target receiver of the wake-up association is not the STA, and the STA stops receiving and handling the wake-up association.

Relationship between the distance and distance parameter r of calculating can be the size relation of the two, and specifically, the size relation of the two can be used difference and determine, ratio relation also can be used and determine.When being determined using ratio relation, preset fractional threshold such as 1, if the ratio between the distance calculated and distance parameter r are less than or equal to default fractional threshold 1, then indicate that the distance calculated is less than or equal to distance parameter r, on the contrary, if the ratio between the distance calculated and distance parameter r are greater than default fractional threshold 1, then it represents that the distance of calculating is greater than distance parameter r.

It should be noted that, the distance of calculating can be Hamming distance (Hamming distance), i.e., the number of the first wireless interface identification of target in the described wake-up association and the different bits on the first wireless interface identification corresponding position of first wireless device.It can simplify calculating using Hamming distance (Hamming distance) to compare two values.Or, the distance is also possible to Euclidean distance (Euclidean Distance), for example, the first wireless interface identification of the first wireless interface identification of target and first wireless device can be calculated the Euclidean distance between them as two vectors.Alternatively, the distance is also possible to the distance of other mathematical definitions such as Min formula distance (Minkowski Distance).Certainly, the application is not limited to three of the above apart from calculation, can also be any other for calculating the mathematical computations mode of difference between two character strings.

The technical solution of the application described further below is first briefly described the application scenarios of the application.The application can apply but be not limited to Internet of Things (IoT) and wearable Wi-Fi network based on Wi-Fi.Wherein, the wearable Wi-Fi network refers to the Wi-Fi network that mobile phone is formed as virtual access point (SoftAP, also referred to as Mobile AP) and associated wearable device.Equipment (STA) in the above network is to be powered by small-capacity cells, and the equipment has low-power consumption and long-time battery durable demand.

See Fig. 4, it illustrates a kind of structure charts of wireless device provided by the present application.The wireless device can be used as the second wireless device (or being the second equipment) such as AP, can also be used as the first wireless device (or being the first equipment) such as STA.As shown in figure 4, module 100 is wireless device, therefore module 100 is properly termed as wireless device 100.Wireless device 100 includes but is not limited to submodule 101,102,103,104 and 105.

First transceiver of the corresponding wireless device 100 of submodule 101, for a kind of specific implementation of the first wireless interface (being properly termed as aided wake interface) of wireless device 100, its can by aided wake module (such as, WUR module) it provides, it can be used for receiving the wake-up association (WUP) and/or send wake-up association to other wireless devices that other wireless devices are sent And to submodule 102 after receiving wake-up association, i.e. the second transceiver (the second wireless interface) sends wake-up signal, to wake up submodule 102 (the second wireless interface).

Second transceiver of the corresponding wireless device 100 of submodule 102, that is the second wireless interface (is properly termed as principal communication interface), its can by principal communication module (such as, 802.11 module) it provides, it can be used for sending wake-up association and send and receive other message (for example, Wi-Fi frame).

The application scenarios of the application and the specific structure of used equipment is described above, the technical solution of the application is illustrated below by way of two specific embodiments.

Embodiment one

The structure of wake-up association (WUP) in the present embodiment wakes up leading (Wake-up Preamble) and recipient address (Receive Address, RA) as shown in Fig. 2, wake-up association (WUP) includes at least.The recipient address (Receive Address) may include network identity (Network ID) and wake on wireless electricity mark (WUR ID)；Alternatively, the recipient address (Receive Address) can be the combination of network identity (Network ID) and wake on wireless electricity mark (WUR ID)；Alternatively, the recipient address (Receive Address) can be wake on wireless electricity mark (WUR ID).The network identity (Network ID) can be a part of the wake on wireless electricity mark (WUR ID).The recipient address (Receive Address) or wake on wireless electricity mark (WUR ID) can be used to identify the target receiver of the wake-up association.The wake-up association (WUP) is also possible to further comprise 802.11 leading (Legacy 802.11Preamble) of tradition, and/or control information (Control Info), and/or Frame Check Sequence (FCS) and/or authentication information (MIC).

In the present embodiment, main to consider during waking up STA, STA can identify the most r bit-errors occurred in transmission process by the special construction that wake on wireless electricity identifies to correct wake on wireless electricity.It should be noted that, the target wake on wireless electricity mark filled in the wake-up association that AP is sent to STA is zero at a distance from the wake on wireless electricity mark of the STA, i.e., the target wake on wireless electricity mark filled in the wake-up association that the described AP is sent is the wake on wireless electricity mark of the target STA.

The process that AP wakes up STA to wake on wireless electric (WUR) the distribution wake on wireless electricity mark (WUR ID) of a STA and determining distance parameter r and AP can be shown in following steps A1~A5.

Step A1:AP obtains the wake on wireless electricity mark (WUR ID) and distance parameter r of STA.

In one example, AP can obtain the wake on wireless electricity mark (WUR ID) and distance parameter r of STA from a server；The server can be Wi-Fi access controller (Wi-Fi Access Controller).

In another example, AP obtains the wake on wireless electricity mark (WUR ID) and distance parameter r of a STA from one or more wake on wireless electricity identification lists (WUR ID List) being locally stored.Specifically, which can be realized by following steps A111~A114.

Step A111: the AP determines the quantity of at most possible associated STA.The AP can estimate the quantity of the at most possible associated STA of the AP according to concrete application scene, for example, in wearable Wi-Fi network, smart phone is as SoftAP, smart phone can estimate the quantity of the at most possible associated STA of smart phone, for example, up to 100 STA.

Step A112: the AP selects a wake on wireless electricity identification list (WUR ID List) according to the quantity of the at most possible associated STA of the determination from one or more wake on wireless electricity identification lists (WUR ID List) of storage.It is understood that the quantity of wake on wireless electricity mark (WUR ID) listed in the selected wake on wireless electricity identification list (WUR ID List) is greater than or the quantity equal to the AP at most possible associated STA determined.

Step A113: the AP selects a wake on wireless electricity mark as the wake on wireless electricity of the STA from the selected wake on wireless electricity identification list (WUR ID List) identifies (WUR ID).

Step A114: the AP determines the distance parameter r according to the selected wake on wireless electricity identification list (WUR ID List) and selected wake on wireless electricity mark (WUR ID).Wherein, the distance between wake on wireless electricity mark (WUR ID) that any two are different in the selected wake on wireless electricity identification list (WUR ID List) is greater than or equal to (2r+1).Any one wake on wireless electricity mark (WUR ID) has corresponding distance parameter r in the selected wake on wireless electricity identification list (WUR ID List).It should be noted that, in this kind of implementation, it is previously stored with multiple wake on wireless electricity identification lists, a wake on wireless electricity identification list is selected from multiple wake on wireless electricity identification lists, then selects a wake on wireless electricity mark as the wake on wireless electricity mark for needing to generate from the wake on wireless electricity identification list selected.Certainly,

In two examples above, wake on wireless electricity mark and distance parameter be it is pre-generated, not generate online.But below in another example, after wake on wireless electricity mark and distance parameter are a new STA connection AP, AP is that the new STA generates wake on wireless electricity and identifies and distance parameter online.It should be noted that following generating modes can also be used in pre-generated mode, i.e. all STA of AP detection connection, and respectively each STA generates wake on wireless electricity mark and distance parameter using following manner.

In yet another example, AP generates a wake on wireless electricity mark (WUR ID) and calculates distance parameter r.Specific implementation can be realized by following steps A121~A125.

Step A121:AP generates a wake on wireless electricity mark (WUR ID), for example, the bit sequence that a length is N is randomly generated, or the bit sequence that a length is N is generated according to specific algorithm, for example, hash algorithm or Encryption Algorithm.

Step A122:AP calculates the distance between the wake on wireless electricity mark of the generation and the wake on wireless electricity mark of several other associated STA.

Step A123: determining the minimum range in several distances, records the wake on wireless electricity mark and the minimum of the generation Distance.

The step A124:AP A121 to A123 that repeats the above steps has altogether K times, K >=1, for example, K=10 times.

A wake on wireless electricity as STA step A125:AP optimal in selecting K wake on wireless electricity of K generation to identify identifies.Here " optimal " refers to that wake on wireless electricity mark and the minimum range of the wake on wireless electricity of other associated STA mark are maximum in the corresponding K minimum range of the K wake on wireless electricity mark.For ease of description, which can be identified into corresponding minimum range and is known as optimal distance, be denoted as d, the distance parameter determined is denoted as r.AP determines distance parameter r according to the maximum minimum range d.

It should be noted that, the distance parameter r is that the wake on wireless electricity that receiving end can at most be corrected when receiving a wake-up association in the present embodiment identifies the number of bit errors occurred in transmission process, and the number of bit errors occurred in transmission process can embody are as follows: different amount of bits between the wake on wireless electricity mark and the wake on wireless electricity of receiving end itself mark in the wake-up association that receiving end receives.

But, the wake on wireless electricity mark of a STA in the same basic service set (BSS) malfunctions in transmission process and becomes the wake on wireless electricity mark of another STA in order to prevent, to influence the correctness for the error-correction operation that receiving end identifies wake on wireless electricity, the AP needs to guarantee that the distance between wake on wireless electricity mark of the different STA of any two in the same basic service set (BSS) is greater than or is equal to (2r+1).In order to make it easy to understand, being illustrated using the relationship between 5 pairs of above-mentioned parameters of diagram.See Fig. 5, it illustrates wake on wireless marks (WUR ID) and a kind of signal of relationship of distance parameter r.As shown in figure 5, the length of wake on wireless electricity mark is N=24 bit, distance parameter r is 4, and parameter d is 9.Wherein, distance parameter r1, r2 and r3 may also be different.The center of circle of each circle indicates the wake on wireless electricity mark of STA itself in Fig. 5, each radius indicates the distance between the wake on wireless electricity mark that STA receives the different amount of bits that the wake on wireless electricity mark that can at most correct after wake-up association is identified from the wake on wireless electricity of itself, and d1, d2 and d3 are two STA.If any two circle intersection, then the wake on wireless electricity mark of STA malfunction in transmission process and after becoming the wake on wireless electricity mark of another STA, the wake on wireless electricity mark of the error may be fallen in two circles of intersection, then the case where being likely to occur while waking up two STA.

Therefore, d is greater than or equal to 2r+1, that is to say, that r is less than or equal to (d-1)/2.Maximum distance parameter r in order to obtain, then: r=(d-1)/2.It is understood that r is integer, so if d is odd number, then r is (d-1)/2；If d is even number, r is (d/2-1)

Step A2:AP sends the wake on wireless electricity mark (WUR ID) and distance parameter r to the STA by Wi-Fi interface.

In one example, AP can send the wake on wireless electricity mark (WUR ID) and/or the distance parameter r to the STA by common action frame (Public Action Frame) or probing response frame (Probe Response Frame) or association response frame (Association Response Frame) or association response frame (Reassociation Response Frame) etc. again.Wherein, AP sends wake on wireless electricity mark (WUR ID) to STA by association response frame (Association Response Frame) and/or the process of distance parameter r is as shown in Figure 6.

Specifically, wake on wireless electricity mark (WUR ID) and/or the distance parameter r can be used as a new information element (IE) and be loaded in the common action frame (Public Action Frame) or probing response frame (Probe Response Frame) or association response frame (Association Response Frame) or again in association response frame (Reassociation Response Frame) etc..

In addition, in order to improve the safety of transmission, the wake on wireless electricity mark (WUR ID) and/or the distance parameter r be can be through encrypted transmission.In addition, the AP wake on wireless electricity can be identified (WUR ID) by a frame and distance parameter r sends jointly to the STA, and certain AP the wake on wireless electricity can also be identified (WUR ID) by two frames and the distance parameter r is sent respectively to the STA.

Step A3: the STA receives the wake on wireless electricity mark (WUR ID) and distance parameter r by Wi-Fi interface.

Wherein, the STA receives the wake on wireless electricity mark (WUR ID) and distance parameter r that the AP is sent by Wi-Fi interface.The wake on wireless electricity of itself is identified (WUR ID) to the STA and distance parameter r is set as the wake on wireless electricity received mark (WUR ID) and distance parameter r.That is the wake on wireless electricity mark (WUR ID) of itself is set the wake on wireless electricity received mark (WUR ID) by STA, and STA sets the distance parameter r of itself to the distance parameter r received.

It should be noted that, above step A1~A3 is AP to wake on wireless electric (WUR) the distribution wake on wireless electricity mark (WUR ID) of a STA and the process of determining distance parameter r, and following steps A4 and A5 are the processes that AP sends wake-up association to wake on wireless electricity.It might not be included as STA distribution wake on wireless electricity mark and the process for determining distance parameter r but before sending wake-up association to the STA every time, before need to only guaranteeing to send wake-up association, be assigned with wake on wireless electricity mark for the STA and distance parameter r has been determined.

Step A4: the AP generates and sends wake-up association to the STA.

Wherein, when AP generation is sent to the wake-up association of the STA, the target wake on wireless electricity mark (WUR ID) filled in the wake-up association is zero at a distance from the wake on wireless electricity mark (WUR ID) of the STA, i.e., the target wake on wireless electricity mark (WUR ID) that the described AP is filled in the wake-up association is the wake on wireless electricity mark (WUR ID) of the STA.The AP sends the wake-up association to the STA.

Step A5: the STA passes through wake-up association described in WUR interface.When the STA receives wake-up association (WUP), the distance between the target wake on wireless electricity mark carried in the wake-up association received described in the STA calculating and the wake on wireless electricity mark of the STA, for ease of description, calculated distance can be known as calculating distance.

It should be noted that the wake on wireless electricity mark of the STA is the wake on wireless electricity mark that the AP that the STA is received is sent, as described by previous step 3.The number for calculating distance and being used to count the target wake on wireless electricity mark carried in the wake-up association received the bit different from the corresponding bit position that the wake on wireless electricity of the STA identifies.

If calculating distance is less than or equal to distance parameter r, the STA then can be determined that the target receiver of the wake-up association received is itself, to which the STA continues to and handle the wake-up association, and the principal communication module of the STA is waken up according at least to the content of the wake-up association；If calculating distance is greater than distance parameter r, STA if, can be determined that the target receiver of the wake-up association received is not itself, so that the STA stops receiving and handles the wake-up association, not wake up principal communication module (such as Wi-Fi module).

Wherein, the STA wakes up the principal communication module (such as Wi-Fi module) of the STA according at least to the content of the wake-up association, specifically includes but is not limited to following three kinds of modes.

First way, the STA can be the target receiver of the wake-up association and then the principal communication module (such as Wi-Fi module) for waking up the STA according to the STA.

The second way, the STA can obtain the Frame Check Sequence (FCS) carried in the wake-up association, and generate the Frame Check Sequence of the wake-up association, judge whether the Frame Check Sequence of the Frame Check Sequence obtained and generation is identical, whether malfunctions in transmission process with the determination wake-up association；If do not malfunctioned, the STA wakes up the principal communication module (such as Wi-Fi module) of the STA；If error, the STA stops receiving and handles the wake-up association, does not wake up principal communication module (such as Wi-Fi module).

The third mode, the STA can judge whether the wake-up association is true according to the authentication information (MIC) that the wake-up association carries, i.e., what whether the described wake-up association was sent by the associated AP of the STA；If true, the STA wakes up the principal communication module (such as Wi-Fi module) of the STA；If untrue, the STA stops receiving and handles the wake-up association, does not wake up principal communication module (such as Wi-Fi module).

It should be noted that the above second way and the third mode are to whether legal verify the wake-up association before waking up principal communication module.The second way be verification wake-up association whether malfunction in transmission process, the third mode be verification send wake-up association AP whether be and the associated AP of STA.

From the above technical scheme, in the embodiment of the present invention one, (WUR ID) is identified by the wake on wireless electricity of the wake on wireless electricity of AP distribution STA, wake on wireless electricity can be corrected to enable STA and identify the most r bit-errors occurred in transmission process.The mode realizing error correction using channel coding in compared with the prior art and being transmitted using Direct Sequence Spread Spectrum raising wake-up association, the error correction method which provides, the power consumption of WUR are lower.

It should be noted that, compared to the embodiment of the present invention one, in the embodiment of the present invention two, it is main to consider to prevent attacker from intercepting and capturing the target wake on wireless electricity mark in wake-up association, the target wake on wireless electricity mark (WUR ID) that AP is filled in the wake-up association for being sent to STA is randomly selected, and the target wake on wireless electricity identifies (WUR ID) and is less than or equal to the distance parameter r at a distance from the wake on wireless electricity mark of the target STA (STA intended to wake up), the target wake on wireless electricity mark (WUR ID) that AP is filled in the wake-up association for being sent to STA may be different from the wake on wireless electricity of target STA mark.The embodiment of the present invention two is suitable for the smaller scene of wake-up association error probability.

The process that AP wakes up STA to wake on wireless electric (WUR) the distribution wake on wireless electricity mark (WUR ID) of a STA and determining distance parameter r and AP can be shown in following steps B1~B5.

Step B1:AP obtains the wake on wireless electricity mark (WUR ID) and distance parameter r of STA.

In one example, AP can obtain the wake on wireless electricity mark (WUR ID) of the STA from a server With distance parameter r；The server can be Wi-Fi access controller (Wi-Fi Access Controller).In another example, AP obtains the wake on wireless electricity mark (WUR ID) and distance parameter r of a STA from one or more wake on wireless electricity identification lists (WUR ID List) being locally stored.Concrete implementation mode may refer to above-mentioned steps A111~A114 realization.In yet another example, AP generates a wake on wireless electricity mark (WUR ID) and calculates distance parameter r.Specific implementation can be realized by above step A121~A125.

Step B2: the AP sends the wake on wireless electricity mark (WUR ID) and distance parameter r to the STA by Wi-Fi interface.

Step B3: the STA receives the wake on wireless electricity mark (WUR ID) and distance parameter r by Wi-Fi interface.

Unlike embodiment one, the present embodiment is when AP generation is sent to the wake-up association of the STA, the target wake on wireless electricity that AP is filled in the wake-up association for being sent to STA identifies (WUR ID), i.e. target receiver identifies, it is being randomly generated or randomly selected, that is it is different that the target wake on wireless electricity mark (WUR ID) that AP is filled in the wake-up association may identify (WUR ID) from the wake on wireless electricity of target STA (STA intended to wake up), but as shown in Figure 7, the distance between wake on wireless electricity mark for the target wake on wireless electricity mark (WUR ID) and target STA that AP is filled in the wake-up association for being sent to STA will meet preset distance condition, the distance parameter r of target STA itself such as less than or equal to.

Step B5: the STA passes through wake-up association described in WUR interface.The distance between when the STA receives wake-up association (WUP), the wake on wireless electricity of the target wake on wireless electricity mark and the STA that carry in the wake-up association received described in the STA calculating identifies；If the distance calculated is less than or equal to distance parameter r, the STA then can be determined that the target receiver of the wake-up association received is itself, to which the STA continues to and handle the wake-up association, and the principal communication module (such as Wi-Fi module) of the STA is waken up according to the content of the wake-up association；If calculating distance is greater than distance parameter r, STA if, can be determined that the target receiver of the wake-up association received is not itself, so that the STA stops receiving and handles the wake-up association, not wake up principal communication module (such as Wi-Fi module).
