Specific implementation mode

The embodiment of the present invention is described with reference to the attached drawing in the embodiment of the present invention.

The radio frames of the embodiment of the present invention refer to wireless Wi-Fi frames, i.e., by main transceiver or the frame structure of transmission.

The wake-up association of the embodiment of the present invention includes legacy preamble and wake-up association narrow portion, and band is wider than shared by legacy preamble Bandwidth shared by wake-up association narrow portion.Legacy preamble is to be able to be compatible with current wlan system, can send wake-up association The legacy preamble that a bandwidth is 20MHz is sent before narrow portion, the bandwidth shared by wake-up association narrow portion is less than 20MHz.

The embodiment of the present invention can be applied to WLAN (Wireless Local Area Network, WLAN), mesh Preceding WLAN accepted standards are Institute of Electrical and Electric Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11 series.WLAN may include multiple basic service set (Basic Service Set, BSS), a BSS includes an access point (Access Point, AP) and multiple is associated with the non-of the AP The website (None Access Point Station, Non-AP STA) of access point class.

AP is the access point that mobile subscriber enters cable network, major deployments inside family, inside buildings and garden, Typical covering radius be tens meters to rice up to a hundred, it is of course also possible to be deployed in open air.AP is equivalent to a connection wired network and nothing The bridge of gauze, main function are to connect together each wireless network clients, and wireless network is then accessed ether Net.Specifically, AP can be terminal device or the network equipment with Wi-Fi chips.Optionally, AP can be to support The equipment of 802.11ax standards, still optionally further, the AP can be support 802.11ac, 802.11n, 802.11g, The equipment of a variety of WLAN standards such as 802.11b and 802.11a.

STA can be wireless communications chips, wireless sensor or wireless communication terminal.Such as：Support Wi-Fi communication functions Mobile phone, support Wi-Fi communication functions tablet computer, support Wi-Fi communication functions set-top box, support Wi-Fi logical The smart television of communication function, supports the vehicle-mounted logical of Wi-Fi communication functions at the intelligent wearable device for supporting Wi-Fi communication functions Believe equipment and supports the computer of Wi-Fi communication functions.Optionally, STA can support 802.11ax standards, further optional Ground, the website support a variety of WLAN standards such as 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a.

As shown in Figure 1, be the application scenario diagram of a BSS provided in an embodiment of the present invention, the BSS include AP, STA1, STA2 and STA3, STA1, STA2 and STA3 are associated with the AP, and the access point of the embodiment of the present invention can be in the Fig. 1 AP, the targeted sites in the embodiment of the present invention can be the STA in the Fig. 1.

In Wi-Fi network, monitoring of quite a few energy dissipation of STA in no reception signal, current tradition Associated solutions concentrate on the dormancy strategy of optimization STA in 802.11 agreements (802.11b/a/g/n/ac etc.).For example, working as When STA does not have information receiving and transmitting, if considerable energy will be consumed by continuing monitor channel.Therefore dormancy mechanism is introduced so that STA exists No data can enter deep-sleep when receiving and dispatching, to reduce the energy consumption for continuing monitor channel.But when STA is in deep-sleep AP can not be communicated with STA, can be just transmitted between the two after only waiting until STA revivals, this may result in certain time delay. In order to avoid high time delay caused by dormancy mechanism, STA would generally follow certain dormancy strategy timing and wake up, to check whether there is Data need to receive, however which in turn reduces the suspend mode efficiency of STA (because timing revival but no data need to receive and dispatch, compared with Long period suspend mode can consume more energy).

Other than optimizing dormancy strategy, another technology for reducing the energy dissipation caused by STA monitor channels is with low Power wake receiver.With the evolution of WLAN wlan standard, IEEE802.11 working groups are preparing to be connect with waking up Receipts machine to reduce by 802.11 research on standard of power consumption and formulates work for core technology.802.11 standard is in 2016 June sets up study group (Study Group, SG) in IEEE.

It is that receiving device (such as STA) is removed comprising traditional 802.11 main transceivers to wake up receiver as the technology of core Outside, it increases low-power consumption newly and wakes up receiver, as shown in Fig. 2, STA comprising main transceiver and wakes up receiver, the main transceiver simultaneously For receiving and dispatching Wi-Fi radio frames, the wake-up receiver is for receiving wake-up association.

As shown in Fig. 2, after the main transceiver of STA enters deep-sleep, the wake-up receiver revival of low-power consumption starts work Make.If other equipment (AP in such as figure) needs are communicated with the STA, which calls out to the transmission of the wake-up receiver of STA first Awake frame (WUP, Wake Up Packet, WUP) wakes up the main transmitting-receiving that receiver is properly received wake-up STA after the WUP for issuing oneself Dormant state is transferred to after machine, AP is then communicated with the main transceiver of revival.The meeting after the completion of the main transceiver of STA is communicated with AP Wake-up receiver revival into dormant state, while STA begins listening for whether having the WUP for being sent to oneself again, to wake up Main transceiver.The wake-up receiver that the technology uses low-power consumption intercepts channel instead of main transceiver in channel idle, can Effectively reduce the energy dissipation of STA.

Usual STA receive be sent to the wake-up association of itself after wake up main transceiver immediately, but in some scenes, STA wakes up the energy dissipation that main transceiver may result in main transceiver immediately after receiving wake-up association.For example, AP is needed to more A STA broadcast messages or multicast information, since each STA is using the structure of Fig. 2, AP in broadcast message or Before person's multicast information, need to wake up multiple STA.

It is specific optional, after AP obtains channel access power by competition, in the same transmission opportunity (Transmission Opportunity, TXOP) in continuously send WUP frames to multiple STA, if STA is received and is sent to the WUP of itself and just calls out immediately The main transceiver of the awake STA, then can lead to energy dissipation.Because the STA being first waken up needs the STA being waken up after waiting for whole Just have an opportunity to receive the broadcast message or multicast information of AP after waking up, STA wakes up main transceiver in advance can only increase STA Power consumption.

Based on the above issues, optionally, the embodiment of the present invention proposes a kind of improved website awakening method, when calling out for STA Awake receiver receives be sent to itself WUP after, continue detect channel free time length whether reach the first duration, this first when It is long to be more than frame pitch, because AP is needed to continuously transmit multiple WUP and can be sent with preset frame pitch.If detecting letter The free time length in road reaches frame pitch, then it is assumed that and AP does not continue to send WUP, and the wake-up receiver of STA can wake up main transceiver, After the main transceiver is waken up, the radio frames of AP transmissions can be received.

Optionally, if waking up receiver detects that the free time length of channel is not up to the first duration, mesh is further determined that Whether the mark moment detects the wake-up association narrow portions of other wake-up associations, the object time be to receive wake-up association finish time from The second duration corresponding at the time of, this second when a length of preset AP when continuously transmitting multiple wake-up associations, it is previous to call out Spacing between wake-up association narrow portion finish time to the wake-up association narrow portion start time of the latter wake-up association of awake frame. If the wake-up association narrow portion of other wake-up associations is not detected in the object time, the wake-up receiver of STA wakes up main transceiver, After the main transceiver is waken up, the radio frames of AP transmissions can be received.

Optionally, if the object time detects that the wake-up association narrow portion of other wake-up associations, STA further determine that this Whether other wake-up associations are to be sent with the associated AP of the STA, if not being sent with the associated AP of the STA, then the wake-up of STA receives Machine wakes up main transceiver, after which is waken up, can receive the radio frames of AP transmissions.

Optionally, if other wake-up associations are sent with the associated AP of the STA, detection can be continued with other wake-ups Whether channel is idle in the first duration from the frame end moment, to recycle execution above-mentioned steps.

Optionally, the embodiment of the present invention also provides a kind of website awakening method, refers to comprising wake-up in each wake-up association Show information, wake-up instruction information is used to indicate whether to wake up main transceiver immediately.For example, STA, which is received, is sent to itself After wake-up association, the wake-up instruction information entrained by the wake-up association is detected, it, should if wake-up instruction information instruction wakes up immediately The wake-up receiver of STA wakes up main transceiver immediately.If wake-up instruction information instruction need not wake up immediately, which can To continue to monitor next wake-up association, and the instruction information of the wake-up entrained by next wake-up association is parsed, if this next is called out The instruction information instruction of the wake-up entrained by frame of waking up wakes up immediately, then the wake-up receiver of the STA wakes up main transceiver immediately.

By above-mentioned website awakening method, main transceiver can be waken up in advance to avoid STA, to save the power consumption of STA.

Fig. 3 is please referred to, Fig. 3 is a kind of flow chart of website awakening method provided in an embodiment of the present invention, and the present invention is implemented The targeted sites of example can be the arbitrary STA in Fig. 1, and the targeted sites in the embodiment of the present invention have the knot of STA in Fig. 2 Structure, i.e. targeted sites include main transceiver and wake-up receiver.As shown, the website awakening method is including but not limited to as follows Step：

Step S101：The first wake-up association that wake-up receiver reception access point is sent, the reception of first wake-up association The address matching of location and the targeted sites；

Step S102：Described wake up receives the free time length of machine testing channel and whether reaches the first duration, when described first Long to be more than frame pitch, the frame pitch is that described access point continuously transmits the spacing in multiple frames between any two consecutive frame； If the free time length of the channel reaches first duration, S103 is thened follow the steps；If the free time length of the channel does not reach To first duration, S105 is thened follow the steps；

Step S103：The main transceiver for waking up receiver and waking up the targeted sites.

Step S104：The radio frames that the main transceiver described access point is sent, the radio frames are the access The radio frames that point is sent at least one website.

Step S105：If the free time length of the channel is not up to first duration, the wake-up receiver determines mesh Whether the mark moment detects that the wake-up association narrow portion of the second wake-up association, the object time are to receive first wake-up association At the time of corresponding to the second duration from wake-up association narrow portion finish time；If the object time is not detected described second The wake-up association narrow portion of wake-up association, thens follow the steps S103；If the object time detects calling out for second wake-up association Awake frame narrow portion, thens follow the steps S106；

Optionally, since wake-up association is there are different frame structures, step 105 may include following two optional embodiment party Formula：

The first optional embodiment is：If the free time length of the channel is not up to first duration, described to call out Awake receiver determines whether object time detects the wake-up association narrow portion of the second wake-up association, and the object time is to receive At the time of corresponding to the second duration from the wake-up association narrow portion finish time for stating the first wake-up association, described second when a length of institute State the sum of the length of frame pitch and the legacy preamble；

Second of optional embodiment be：If the free time length of the channel is not up to first duration, described to call out Awake receiver determines whether object time detects the wake-up association narrow portion of the second wake-up association, and the object time is to receive At the time of corresponding to the second duration from the wake-up association narrow portion finish time for stating the first wake-up association, this described second when it is a length of The sum of the frame pitch, the length of the legacy preamble and described default spacing；

Step S106：If the object time detects the wake-up association narrow portion of second wake-up association, the wake-up Receiver determines whether second wake-up association is to be sent with the associated described access point of the targeted sites；If described second calls out Awake frame is sent with the associated access point of the targeted sites, and S103 is thened follow the steps；If second wake-up association is and institute It states the associated access point of targeted sites to send, thens follow the steps S102；

As an alternative embodiment, after AP competitions obtain channel, sent to one or more STA in TXOP Wake-up association, it should be noted that when AP continuously sends wake-up association in the same TXOP to multiple STA, two continuous wake-ups Frame pitch between frame is xIFS.XIFS can be short frame period (Short Interframe Space, SIFS).Below with this A target STA in multiple STA illustrates the wakeup process of STA as an example, it is to be understood that each in multiple STA The processing procedure of STA is all identical as the processing procedure of target STA of the embodiment of the present invention.

The wake-up receivers of targeted sites receives the first wake-up association, parses the reception address of first wake-up association, and by the The reception address of one wake-up association is matched with the address of the targeted sites, if matching is consistent, illustrates that first wake-up association is It is sent to the targeted sites.It, will not after the wake-up receiver of targeted sites receives the first wake-up association for being sent to itself It immediately begins to wake up the main transceiver of the targeted sites, and is to continue with detection channel.

The wake-up of targeted sites receive machine testing with receive channel from the first wake-up association finish time free time length whether Reach the first duration, which can be indicated with yIFS, it should be noted that first duration yIFS needs are more than Frame pitch xIFS.If the wake-up receiver of targeted sites detects that the free time length of channel reaches the first duration, illustrate the AP Do not continue to send wake-up association, which can wake up main transceiver, after the main transceiver revival of targeted sites, you can receive The radio frames that AP is sent.As shown in Figure 6 a, if targeted sites be STA3, STA3 receive be sent to oneself WUP3 it Afterwards, whether the free time length for continuing to detect channel reaches yIFS, if free time length reaches yIFS, the wake-up receiver of STA3 is called out The main transceiver of awake STA3, AP broadcast messages or multicast information.

Optionally, if the wake-up receiver of targeted sites is detected with the sky of channel from the first wake-up association finish time of reception Idle length is not up to the first duration, i.e., in the yIFS times of targeted sites waken up after receiver receives the first wake-up frame end Channel busy then illustrates that possible AP has and continues to send wake-up association.Therefore the wake-up receiver of targeted sites determines that object time is The no wake-up association narrow portion for detecting the second wake-up association, the object time are to receive the from the first wake-up association finish time At the time of corresponding to two durations (for example it is 56 microseconds to receive for the first wake-up association finish time, second when a length of 36 microsecond, then target Moment is 92 microseconds), the embodiment of the present invention indicates the second duration using zIFS.It should be noted that the second duration can be pre- When the AP first set continuously transmits multiple wake-up associations according to chronological order, between the wake-up association narrow portion of adjacent wake-up association Away from being the wake-up association narrow portion finish time of previous wake-up in the adjacent wake-up association to the wake-up association of the latter wake-up association Spacing between narrow portion start time.

Optionally, as shown in figures 4 a and 4b, wake-up association may exist two kinds of optional structures.Since wake-up association exists not Same frame structure, therefore the definition of the second duration is also different.For example, as shown in fig. 4 a, the legacy preamble (legacy of wake-up association Preamble it) is located next in time with the wake-up association narrow portion of the wake-up association, if wake-up association is the frame structure of Fig. 4 a, the Two durations can be the sum of length and frame pitch of legacy preamble.As shown in Figure 4 b, the legacy preamble of wake-up association and the wake-up association Wake-up association narrow portion between retain a default spacing, which is indicated with wIFS, then this second when it is a length of The sum of length, frame pitch and default spacing of legacy preamble.It should be noted that for waking up frame structure shown in Fig. 4 b, AP is the legacy preamble for first sending 20MHz, and the wIFS times is then waited for retransmit the wake-up association narrow portion of wake-up association later.

For the frame structure of wake-up association shown in Fig. 4 a, the length of the second duration zIFS=xIFS+Legacy preamble Degree；For the frame structure of wake-up association shown in Fig. 4 b, the length of zIFS=xIFS+wIFS+legacy preamble.Wherein, XIFS indicates that frame pitch, wIFS indicate the spacing between the legacy preamble and the wake-up association narrow portion of wake-up association of wake-up association.

Legacy preamble generally use structure shown in fig. 5 is divided into L-STF (8us), L-LTF (8us) and L-SIG (4us) three Part, total length amount to 20us.

Optionally, the wake-up association narrowband of the second wake-up association is not detected in object time when the wake-up receiver of targeted sites Part then illustrates that channel busy may be since other websites done caused by radio frame transmission in the first duration Disturb, or as caused by non-Wi-Fi signal it is busy, and with the associated AP of the targeted sites stopped send wake-up association, because The main transceiver of the main transceiver of the wake-up receiver wake up target website of this targeted sites, targeted sites can receive AP transmissions Radio frames.

As shown in Figure 6 b, if targeted sites are STA4, STA4, which is received, to be sent to after the wake-up association WUP4 of itself, detection The free time length of channel is not up to yIFS, and corresponding to the zIFS durations from STA4 receives wake-up association WUP4 finish times The wake-up association narrow portion of other wake-up associations is not detected in moment, then the wake-up receiver of STA4 can wake up the main transmitting-receiving of STA Machine, AP broadcast messages or multicast information.

Optionally, the wake-up association narrowband portion of the second wake-up association is detected in object time when the wake-up receiver of targeted sites Point, it needs to further determine that whether second wake-up association is to send with the associated AP of the targeted sites.If second wake-up association It is not by being sent with the associated AP of targeted sites, then explanation may stop sending wake-up association with the associated AP of targeted sites. The main transceiver of the main transceiver of the wake-up receiver wake up target website of targeted sites, targeted sites can receive AP transmissions Radio frames.It should be noted that second wake-up association is not by being sent with the associated AP of targeted sites, but the targeted sites are still Second wake-up association can be so received, which may be by Overlapping Basic Service Set (Overlapping Basic Service Set, OBSS) AP send wake-up association.

Optionally, if second wake-up association is sent with the associated AP of the targeted sites, illustrate the AP also after supervention Send whether wake-up association, the free time length that the wake-up receiver of targeted sites also needs to continue to detect channel reach the first duration, need It is noted that if AP is to continuously transmit multiple wake-up associations, targeted sites detection by interval of frame pitch in a TXOP It is whether idle with channel in the first duration from the second wake-up association finish time of reception.

Continue with Fig. 6 a as an example, for example targeted sites are the STA1 in Fig. 6 a, STA1 is sent to receiving After the wake-up association WUP1 of itself, the free time length for detecting channel is not up to yIFS, then STA1 continues detection to receive WUP1 knots Whether the wake-up association narrow portion of second wake-up association is detected at the time of corresponding to zIFS durations after beam, as shown in Figure 6 a, STA1 is in the zIFS (length or zIFS=xIFS+wIFS+legacy of zIFS=xIFS+Legacy preamble here The length of preamble) corresponding at the time of detect the wake-up association narrow portion of WUP2, and the STA1 further determines that this WUP2 is the wake-up association sent with the associated AP of STA1, then STA1 needs whether the free time length of further detection channel reaches the One duration yIFS, whether STA1 is idle to receive channel in the first duration yIFS from WUP2 finish times here.

It should be noted that in Fig. 6 a, detection only can be just executed after STA receives the wake-up association for being sent to itself The whether idle step of channel, for example, when STA2 receives WUP1, due to the WUP1 the address for receiving address and STA2 not Matching, therefore the STA will not further parse the WUP1, and monitor channel is only will continue to, to receive next WUP.In Fig. 6 a Any one STA all can serve as the targeted sites of the embodiment of the present invention, be sent to calling out for itself when targeted sites receive It wakes up after frame, can execute the website awakening method of the embodiment of the present invention.

Optionally, AP can send multiple wake-up associations in multiple wake on wireless radio channels, be sent in the embodiment of the present invention The first wake-up association to targeted sites is a wake-up association in multiple wake-up association, and the channel for carrying first wake-up association is should A wake on wireless radio channel in multiple wake on wireless radio channels.If the wake-up that the channel for carrying first wake-up association is carried The quantity of frame is less than the quantity for the wake-up association that other wake on wireless radio channels are carried, then the wake-up association of the channel can be caused to correspond to STA ahead of time wake up main transceiver.

Below as an example with Fig. 6 c, as fig. 6 c, AP can be sent in WUR channels 1 and WUR channels 2 respectively Multiple wake-up associations, it is assumed that the wake-up number of frames that WUR channels 2 are carried is less than WUR channels 1, as shown, what WUR channels 1 carried The quantity of wake-up association is that the quantity for the wake-up association that 3, WUR channels 2 are carried is 2, since STA b1 and STA b2 receive STA b2 WUP after channel is all in idle state in the yIFS times, therefore STA b1 and STA b2 will wake up main transmitting-receiving ahead of time Machine, but AP due to be to STAa1, STA a2, STA a3, STA b1 and STA b2 broadcast messages or multicast information, because This AP can just understand broadcast message or multicast information after STA a3 finally wake up main transceiver.Can cause in this way STA b1 and STA b2 wake up main transceiver ahead of time, cause energy dissipation.

In order to avoid above-mentioned energy dissipation problem, the embodiment of the present invention wakes up the few wake on wireless telecommunications of number of frames in carrying Increase third wake-up association on road, the reception address of the third wake-up association is virtual address, be the third wake-up association is not hair Give some specific STA.

As fig. 6 c, since the wake-up number of frames that WUR channels 2 are carried is less than the wake-up frame number that WUR channels 1 are carried Amount, therefore AP can send one on WUR channels 2 and receive the wake-up association that address is virtual address, be sent to STA X's in Fig. 6 c WUP, which is one, receives the wake-up association that address is virtual address.STA b1 in this way and STA b2 are terminated with the WUP for receiving STA b2 Channel is in idle condition in the yIFS times risen, and can just wake up main transceiver, to STA a1, STAa2, STAa3, STA b1 And STA b2 wake up the time consistency of main transceiver.

When the wake-up receiver of targeted sites wakes up main transceiver, it is assumed that the wake-up receiver of targeted sites wakes up main transmitting-receiving The wakeup time of machine is that T reuses master after then AP should wait for at least T+zIFS times after having sent WUP to a STA Radio channel broadcasts information or multicast information.

As another optional embodiment, when AP not only sends wake-up association in the same TXOP, but also using main wireless Radio channel sends the radio frames of 20MHz, and the frame pitch between wake-up association and radio frames remains as xIFS.In such a scenario, mesh The wake-up receiver of labeling station point after receiving and being sent to the WUP of oneself, will not wake up target website immediately main transceiver, And it is to continue with detection channel, the main transceiver of wake up target website immediately after the continuous free time length of channel reaches yIFS.It needs It is noted that yIFS here is needed not be to receive in the yIFS durations from WUP finish times, channel is any continuous When being in idle condition in yIFS durations, the wake-up receiver of targeted sites can wake up main transceiver.If this is because AP It is when channel sends radio frames, waking up receiver can not be parsed, and the wake-up receiver of targeted sites is merely capable of detecting It is to be in busy state to channel, when AP has sent radio frames, the wake-up receiver of targeted sites detects that channel is in sky Not busy state, after being spaced frame pitch xIFS durations, AP sends wake-up association again, then the wake-up receiver of targeted sites can detect again It is in busy state to channel.Since targeted sites can not parse radio frames, the wake-up receiver of targeted sites is only logical It crosses and judges the busy-idle condition of channel to determine the need for waking up main transceiver, i.e., determined by judging the busy-idle condition of channel Whether AP terminates to send all wake-up associations in the TXOP.

As shown in fig 6d, AP first sends WUP5 to STA5, is then giving STA6 transmission data packets using main radio channel Data6 sends WUP7 after sending Data6, then to STA7.Frame pitch between any two consecutive frame is xIFS. STA5 receives AP and is sent to after the WUP5 of oneself, does not wake up main radio immediately, and is to continue with detection channel.Until STA5 just detects that the continuous free time length of channel reaches yIFS after WUP7 is sent, therefore from reception WUP7 finish times STA5 just wakes up main transceiver immediately after yIFS durations.

STA7 receives AP and is sent to after the WUP7 of oneself, does not wake up main transceiver immediately, and is to continue with detection channel. Channel is in idle condition in the yIFS durations from receiving WUP7 finish times, and the wake-up receiver of STA7 wakes up main receipts immediately Hair machine.

When the wake-up receiver of targeted sites wakes up main transceiver, it is assumed that the wake-up receiver of targeted sites wakes up main transmitting-receiving The wakeup time of machine is T, then AP should wait for at least T+yIFS times after having sent WUP or radio frames to a STA Afterwards, main radio channel broadcasts information or multicast information are reused.

Fig. 7 is please referred to, is the flow chart of another website awakening method provided in an embodiment of the present invention, as shown in fig. 7, this The website awakening method of inventive embodiments includes but not limited to following steps：

Step S201：The receiver that wakes up receives the first wake-up association that access point is sent, and first wake-up association connects The address matching of address and the targeted sites is received, first wake-up association, which carries, wakes up instruction information；

Optionally, it can be indicated by 1 bit information, or pass through two bit informations to wake up instruction information Indicate etc., the embodiment of the present invention is not construed as limiting this.

If the wake-up instruction information of first wake-up association is first identifier, S202 is thened follow the steps, if first wake-up association Wake-up instruction information be second identifier, then follow the steps S204.

Step S202：If the wake-up instruction information of first wake-up association is first identifier, the wake-up receiver receives At least one second wake-up association that described access point is sent；

Optionally, first identifier is used to indicate wake-up receiver need not wake up main transceiver, therefore targeted sites immediately When receiving the first wake-up association for waking up and indicating information as first identifier, the second wake-up association for continuing to AP transmissions is needed.

Step S203：If the wake-up instruction information of second wake-up association is second identifier, the wake-up receiver wakes up The main transceiver of the targeted sites.

Optionally, the second wake-up association can be destined to the wake-up association of other websites, but targeted sites still can connect Receive second wake-up association.Second identifier is used to indicate wake-up receiver and needs to wake up main transceiver immediately.When targeted sites receive To when waking up second wake-up association of the instruction information for second identifier, main transceiver is waken up immediately.

Optionally, first wake-up association also includes first group of mark being grouped belonging to the targeted sites；

If the wake-up instruction information of second wake-up association is second identifier, the wake-up receiver wakes up the mesh The main transceiver of labeling station point, including：

If the wake-up instruction information of second wake-up association is second identifier, and second group that second wake-up association includes Mark is matched with first group of mark, the main transceiver for waking up receiver and waking up the targeted sites.

Step S204, if the wake-up instruction information of first wake-up association is second identifier, the wake-up receiver wakes up The main transceiver of the targeted sites.

In one embodiment, it wakes up bit immediately by one in WUP and is used as wake-up instruction information, wake-up instruction Information is used to indicate whether website needs to wake up main transceiver immediately.If for example, waking up immediately when bit is 0, representative should not be immediately Main transceiver is waken up, if it is that 1 representative wakes up main transceiver immediately to wake up bit immediately.

After targeted sites receive the first wake-up association of AP transmissions, the reception address of first wake-up association is parsed, and will The reception address of first wake-up association is compared with the address of targeted sites, if matching is consistent, illustrates that first wake-up association is It is sent to the wake-up association of targeted sites.

After targeted sites receive the first wake-up association for being sent to oneself, the wake-up immediately of first wake-up association is parsed Bit wakes up main transceiver immediately if waking up bit immediately and being set as 1.It is not stood if waking up bit immediately and being set as 0 Main transceiver is waken up, and is to continue with monitor channel to receive next second wake-up association.Until receive one by with the mesh The second wake-up association that the associated AP of labeling station point is sent, and the bit of wake-up immediately of second wake-up association is set as 1, targeted sites Wake-up receiver wake up main transceiver immediately.It should be noted that second wake-up association can not be and be sent to the Target Station The wake-up association of point.

As shown in Figure 8 a, AP is taken up in order of priority in STA8, STA9 and STA10 transmission one WUP, wherein the first two WUP Bit is waken up immediately and is set as 0, the bit of wake-up immediately of the last one WUP is set as 1.It is sent to oneself when STA8 receives AP WUP8 after, due to wake up immediately bit be 0, so not waking up main transceiver immediately.After STA8 receives WUP9, by It is 0 in waking up bit immediately, does not still wake up main transceiver.After STA8 receives WUP10, since WUP10 is by being associated with AP is sent, and it is that 1, STA8 wakes up main transceiver immediately to wake up bit immediately.

It is 0 due to waking up bit immediately, so not waking up immediately after STA9, which receives AP, is sent to the WUP9 of oneself Main transceiver.After STA9 receives WUP10, since WUP10 is to be sent by associated AP, and it is 1 to wake up bit immediately, STA9 wakes up main transceiver immediately.

It is that 1, STA10 is called out immediately due to waking up bit immediately after STA10, which receives AP, is sent to the WUP10 of oneself Awake main transceiver.

Optionally, wake-up association can also include group mark, and group mark can be a group address.Multiple STA have phase Same group mark, AP can be to multiple STA broadcast messages or multicast information with identical group of mark.

It is entrained in first wake-up association by parsing after targeted sites receive the first wake-up association for being sent to oneself Group mark, obtain grouping belonging to the targeted sites.When the wake-up instruction information of the first wake-up association indicates that the targeted sites are not required to Main transceiver is waken up immediately, then the wake-up receiver of the targeted sites continues to the second wake-up association, if second wake-up association Wake-up instruction information instruction wake up main transceiver immediately, then the targeted sites by group mark entrained in the second wake-up association with The group mark being grouped belonging to the targeted sites is matched, if matching is consistent, the main transceiver of wake up target website.

It is specific optional, continue here to wake up instruction information to be to wake up bit as an example immediately, as a STA It receives AP to be sent to after the WUP of oneself, main transceiver is waken up immediately if waking up bit immediately and being set as 1.If vertical I.e. wake-up bit is set as 0 and does not wake up main transceiver immediately then, and STA continues to parse group mark entrained in the WUP, and adds Enter the indicated grouping of group mark.STA continues monitor channel to receive next WUP, until receiving one by associated AP Group mark in the WUP of transmission, the WUP is identical as the group mark being grouped belonging to the STA, and the wake-up immediately of the WUP is than ad hoc It is set to 1, the wake-up receiver of the STA wakes up main transceiver immediately.Optionally, after STA wakes up main transceiver, institute can be discharged The grouping of addition, in order to which other websites reuse the grouping.

As shown in Figure 8 b, AP is taken up in order of priority sends WUP, wherein the first two WUP (WUP11 to STA11, STA12 and STA13 And WUP12) in the bit of wake-up immediately be set as 0, waken up immediately in the last one WUP (WUP13) than being set as 1, three Group address setting in WUP is identical, for example group address is all set as 7.

It is 0 due to waking up bit immediately, so not calling out immediately after STA11, which receives AP, is sent to the WUP11 of oneself Awake main transceiver, and the grouping that address is 7 is added.It is 0 due to waking up bit immediately, still after STA11 receives WUP12 So main transceiver is not waken up.After STA11 receives WUP13, since WUP13 is sent by associated AP, bit is waken up immediately It is 1, and group address is set as 7, then STA11 wakes up main transceiver immediately.

It is 0 due to waking up bit immediately, so not calling out immediately after STA12, which receives AP, is sent to the WUP12 of oneself Awake main transceiver, and the grouping that group address is 7 is added.After STA12 receives WUP13, since WUP13 is sent out by associated AP It send, it is 1 to wake up bit immediately, and group address is set as 7, therefore STA12 wakes up main transceiver immediately.

It is that 1, STA13 is called out immediately due to waking up bit immediately after STA13, which receives AP, is sent to the WUP13 of oneself Awake main transceiver.Work as after STA11, STA12 and STA13 wake up main transceiver, all exited from grouping 7, which can be by Other websites utilize.

By implementing the embodiment of the present invention, indicate that information determines the need for waking up master immediately by the wake-up in wake-up association Transceiver saves power consumption to avoid website from waking up main transceiver in advance.
