Fig. 1 is the flow chart of configured information sending method embodiment one of the present invention, as shown in figure 1, the method for the present embodiment It can include：

Step 101, channel is monitored since time slot initial time.

If step 102, monitoring that non-slotted channel is idle before point from time slot initial time to preset time, time slot is judged Free time, in preset time point at least one website sending time slots free time configured information, so as to have data to the website root sent Channel is used according to remaining time of the time slot free time configured information in the time slot.Monitor the point from time slot initial time to preset time Non-slotted channel is idle before, can include：Any website hair is not monitored before the point from time slot initial time to preset time Data are sent, or, does not monitor to be assigned the website that data are sent in current time slots in current time slots transmission data and does not monitor To the website that data are sent in the previous time slot of current time slots data are sent in current time slots；Working as not monitoring to be assigned The websites of data is sent in preceding time slot to send data in current time slots and do not monitor to send in previous time slot in current time slots For the website of data when current time slots send data, if there is illegal website, such as the website of unassigned time slot is when time slot is initial It is carved between preset time point and sends data, now still it is considered that current time slots channel idle, and the sending time slots free time refers to Show information, so that the legal website for having data to send uses channel in the remaining time of the time slot, such case can be kept away Exempt from illegal website and illegally send data, improve the security of network.

Specifically, do not allow website cross the border transmission when, in RAW, the send opportunity of website can not cross the side of time slot Boundary, i.e., any time slot in RAW, at most an only website can be with reported data, and thus, there is no asking for hiding website Topic.Website is not allowed to cross the border in the case of transmission, preset time point can be time slot initial time, or be opened from time slot initial time At the time of after the duration of one competition phase of delay beginning, the competition phase is a period of time that website competition obtains channel, and access point is in RAW It is interior not monitor that any website sends data before point from time slot initial time to preset time, or do not monitor to be assigned and working as The website that the website of data is sent in preceding time slot and does not monitor to send data in the previous time slot of current time slots sends data, The time slot free time is can determine whether, and the website for having data to send is given in preset time point sending time slots free time configured information, until After the website that all unfinished data are sent has sent remaining data, access point can stop regularly monitoring channel.

Allow to cross the border when sending data, alternatively, preset time point can be time slot initial time, or from time slot it is initial when At the time of quarter after the duration for starting one competition phase of delay, or postpone since the time slot initial time a sync period duration and At the time of after the duration of one competition phase, sync period is site channel synchronous a period of time.

Alternatively, before access point monitors channel since time slot initial time, terminate in the previous time slot of current time slots When, if indicating still to have data to send in the data frame received, judge that current time slots there are the data for transmission of crossing the border, then not The channel of current time slots is monitored, and is crossed the border configured information to website broadcast transmission in current time slots initial time, cross the border instruction letter Cease has the data for transmission of crossing the border for indicating website in current time slots, so that the website that current time slots are assigned is not in current time slots Interior transmission data, channel is monitored since time slot initial time, is specifically as follows：If the data for transmission of not crossing the border, start Monitor channel.If website receives the configured information of crossing the border of access point transmission, website does not have to carry out channel synchronization, can be further Power saving.

In a step 102, do not allow website cross the border transmission when, the website for having data to send can be included in when being assigned The website and/or unassigned time slot but the website for having data to transmission of data have not been sent in gap.Allow website cross the border transmission when, The website for having data to send, which can be included in, to be assigned the website for not sending data in time slot and/or unassigned time slot but has number According to the website to be sent.

Access point monitors channel since time slot initial time, if the non-slotted channel free time is monitored, when access point judges this Gap is idle, then in preset time point at least one website sending time slots free time configured information, so as to have data to what is sent Website uses channel according to time slot free time configured information in the remaining time of the time slot, access point periodic monitoring channel, is monitoring Sending time slots free time configured information after to time slot channel idle, until without untill not completing the website presence that data are sent. In the present embodiment, time slot free time configured information can use the non-competing polling message for having quality of service guarantee in existing standard QoS CF-Poll form, if existing or having and be assigned time slot being assigned the website for not sent data in time slot The website for not sending data inside is present, can be in the reception address of QoS CF-Poll data frame（ReceiveAddress, with Lower abbreviation：RA）The address of receiving station is set in domain；If it be not assigned not sent data in time slot or is being referred to Send the website for not sending data in time slot to exist, the RA domains of QoSCF-Poll data frame can be arranged to a broadcast ground Location；Time slot free time configured information can also use the no data segment message in existing standard（Null Data Packet, below Referred to as：NDP）The form of CTS message, if being assigned not sent data in time slot or not sending out being assigned in time slot Send the website of data to exist, the address of receiving station can be set in the CTS ID domains of NDP CTS frames；If do not referred to Send do not sent in time slot data or be assigned data are not sent in time slot website exist, can be by NDP CTS frames CTS ID domains are arranged to a broadcast address.

Access point is to website sending time slots free time configured information, so that the website for having data to send refers to according to the time slot free time Show that information uses channel in the remaining time of the time slot, there can be two kinds of enforceable modes：As the first enforceable side Formula, access point is to a website sending time slots free time configured information for having data to send, so that the website is idle according to time slot Configured information uses channel in the remaining time of the time slot.

As second of enforceable mode, access point is to nonspecific website sending time slots free time configured information, so as to have The data one or more websites to be sent compete busy channel and in the remaining time of time slot according to time slot free time configured information Using channel, when access point is to nonspecific website sending time slots free time configured information, it can at random send, also can according to priority send out Send, the embodiment of the present invention is without limitation.

The configured information sending method that the present embodiment provides, channel is monitored by access point since time slot initial time, If non-slotted channel is idle, access point to website sending time slots free time configured information so that have data to send website according to Time slot free time configured information uses channel in the remaining time of time slot, does not allow to cross the border when sending data, can allow when being assigned The website and/or unassigned time slot but the website that has data to send in free timeslot in RAW of data have not been sent in gap Complete to send, it is allowed to during transmission data of crossing the border, can allow and be assigned the website for not sending data in time slot and/or unassigned time slot But the website for having data to send is completed to send in the free timeslot in RAW, so as to improve on channel utilization and website The real-time of count off evidence.

Fig. 2 is the flow chart of data transmission method for uplink embodiment one of the present invention, as shown in Fig. 2 the method for the present embodiment can be with Including：

The preset time point of each time slot of step 201, website after time slot is assigned receives the time slot that access point is sent Idle configured information distributes until data.

Specifically, in the case where not allowing to cross the border and sending data, preset time point can be time slot initial time or from At the time of time slot initial time starts after the duration of one competition phase of delay, when the competition phase is that website competition obtains one section of channel Between.

In the case where allowing to cross the border and sending data, preset time point can be time slot initial time or from time slot it is initial when At the time of quarter after the duration for starting one competition phase of delay, or postpone since the time slot initial time a sync period duration and At the time of after the duration of one competition phase, sync period is site channel synchronous a period of time.

Step 202, according to time slot free time configured information, send data.Time slot free time configured information is that access point is monitoring Non-slotted channel is idle before to the point from time slot initial time to preset time, then judges that time slot is idle, preset time point to this The time slot free time configured information that website is sent.Monitor that non-slotted channel is idle before point from time slot initial time to preset time, Including：Do not monitor that website sends data before the point from time slot initial time to preset time, or, do not monitor to be assigned The websites of data is sent in current time slots to send data in current time slots and do not monitor to send out in previous time slot in current time slots The website of data is sent to send data in current time slots.

Specifically, data are sent according to time slot free time configured information, including：According to time slot free time configured information, and confirm When itself being the purpose website of time slot free time configured information, then data are sent in the remaining time of current time slots.

The data transmission method for uplink that the present embodiment provides, passes through the preset time of each time slot of the website after time slot is assigned The time slot free time configured information of point reception access point transmission distributes until data, and sends number according to time slot free time configured information According to the problem of so as to avoid hiding website, improving the real-time of channel utilization and website reported data.

In the case where allowing to cross the border and sending data, Fig. 3 is the flow chart of data transmission method for uplink embodiment two of the present invention, such as Shown in Fig. 3, the method for the present embodiment can also include：

Step 301, it is informed in the data for being assigned and having transmission of crossing the border on time slot.

Step 302, data are not sent in described be assigned on time slot.

Specifically, whether stations aware has the data for transmission of crossing the border to have two kinds of enforceable sides on time slot is assigned Formula.As a kind of enforceable mode, before channel synchronization terminates, whether monitoring is informed in be assigned on time slot has more website The data that boundary is sent, are specifically included：

First, in synchronizing process, website does not hear any message, is informed in the number for being assigned transmission of not crossed the border on time slot According to website begins to use after same the end of the step is assigned time slot transmission data.

2nd, in synchronizing process, website is informed in be assigned on time slot according to the data frame or confirmation message heard to be had more The data that boundary is sent, website do not send data on time slot is assigned.Specifically, website can also be taken according in the data frame heard Whether the data frame for being used to indicate to hear of band is last frame or confirms the information of the confirmation message of last frame, it is determined whether It is continuing with being assigned time slot.Specially：

Website terminates synchronously, that is, after hearing that other website is sent to the message of access point after hearing a up data frame Terminate synchronous.Website can be judged to cross the border according to the indicating bit for indicating whether to have next data frame in data frame website whether May proceed to busy channel, the website that crosses the border refer to be assigned in time slot do not send data or do not sent data and when being assigned Next time slot of gap sends the website of data.If the data frame is last frame, website after the data frame end, Wait the confirmation message ACK message of an access point, then access channel and use and be assigned time slot transmission data, herein due to The problem of hiding website, website, which differs, surely hears up data frame.Or

Website hears an access point to the descending ACK message for website transmission of crossing the border, according to the finger carried in ACK message Show whether the ACK message confirm is whether the information website that judges to cross the border of last data frame may proceed to busy channel, if What the ACK message confirmed is last data frame, then website accesses channel after the ACK message terminates and use is assigned Time slot sends data.

Stations aware does not send data after the data for having transmission of crossing the border on time slot are assigned on time slot is assigned, this Shi Zhandian can carry out dormancy processing, not access channel, also collect data etc..Website starts delay one in next time slot afterwards Waken up after at the time of after the duration of competition phase and attempt to receive the time slot free time configured information that access point is sent, if receiving time slot sky Not busy configured information, then data are sent in the remaining time of the time slot, if not receiving time slot free time configured information, continue to stop Sleep.

As another enforceable mode, website is being assigned getting over for time slot initial time trial reception access point transmission Boundary's configured information, if receiving configured information of crossing the border, being informed in be assigned on time slot according to configured information of crossing the border has the hair that crosses the border The data sent, now can be without channel synchronization.Website starts to prolong after configured information of crossing the border is received in next time slot Dormancy before at the time of after the duration of a slow competition phase, and when next time slot starts after one duration for competing the phase of delay Waken up after quarter and attempt to receive the time slot free time configured information that access point is sent, if time slot free time configured information is received, at this The remaining time of time slot sends data, if not receiving time slot free time configured information, continues dormancy.Now website is without carrying out Channel synchronization and keep out of the way（Backoff）, thus more power saving, while the problem of it also avoid hiding website, improve channel profit With rate and the real-time of website reported data.

The data transmission method for uplink that the present embodiment provides, there is the number for transmission of crossing the border on time slot is assigned by stations aware According to data are not sent on time slot is assigned then.The problem of so as to avoid hiding website so that website more power saving, improve The real-time of channel utilization and website reported data.

Several specific embodiments are used below, and the technical scheme of above method embodiment is described in detail.

Fig. 4 is configured information sending method of the present invention, the schematic diagram of data transmission method for uplink embodiment one.It is assumed to be in figure every One website is assigned（Distribute）One time slot, such as assign the first time slot for the first website.An as shown in figure 4, beacon period Interior limitation turn-on time window RAW is divided into multiple time slots, and each time slot is assigned with corresponding website and sends number on the time slot According to, when not allowing the website to cross the border, any time slot in RAW, at most only website can with reported data, access point from when Gap initial time starts to monitor channel, and access point does not only monitor in RAW from time slot initial time to preset time before point Any website sends data, or does not monitor to be assigned and the website of data is sent in current time slots and in the previous of current time slots The website that data are sent in time slot sends data, just can start regularly to supervise in the time slot initial time for being assigned time slot website Survey channel.After the website that all unfinished data are sent has sent remaining data, access point stops monitoring channel.If monitoring To time slot channel idle, access point thinks the time slot free time, and then access point is to website sending time slots free time configured information, so that The website that one or more has data to send sends data according to remaining time of the time slot free time configured information in the time slot, Until exist without the website for not completing data transmission.Access point is to website sending time slots free time configured information, so as to there is number According to the website to be sent according to time slot free time configured information time slot remaining time send data can have two kinds it is enforceable Mode：First, access point can be to a website sending time slots free time configured information for having data to send, so that the website root Channel is used according to remaining time of the time slot free time configured information in time slot.Further, if the website current time slots residue Data have been sent in time, then can no longer wake up, if not sent, time slot free time configured information can be continued to. In such cases, if needing to send with the presence of the website remaining data for being assigned time slot, access point can record the address of the website, And it is sent to time slot free time configured information.

Second, access point can be to nonspecific website sending time slots free time configured information, so as to have data to one sent Or multiple websites compete busy channel according to time slot free time configured information and use channel in the remaining time of time slot.Further Ground, if the website for having data to send has sent data within the remaining time of current time slots, can no longer it wake up, if not having It has been sent that, then can continue to time slot free time configured information.Access point is to nonspecific website sending time slots free time configured information When, it can at random send, also can according to priority send, can also be sent by website order, the embodiment of the present invention is without limitation.

Fig. 5 is configured information sending method of the present invention, the schematic diagram of data transmission method for uplink embodiment two.It is assumed to be in figure every One website assigns a time slot, such as assigns the first time slot for the first website.As shown in figure 5, the limitation in a beacon period Turn-on time window is divided into multiple time slots, and each time slot is assigned with corresponding website and sends data on the time slot, it is allowed to website When crossing the border, website is waken up in the boundary of time slot for distributing to oneself, carries out channel synchronization first, website during channel synchronization, If hearing a complete frame, website terminates synchronizing process.If website does not hear any one during channel synchronization Individual complete frame, the time that website needs to monitor is detection time delay ProbeDelay, could terminate channel synchronization process. ProbeDelay length is at least greatest physical layer data unit（PLCP protocol Data Unit, hereinafter referred to as： PPDU）The transmission time add two short frame periods（Short Inter Frame Space, hereinafter referred to as：SIFS）Time The long transmission time for adding a confirmation message ACK, so do, even if the website for transmission of crossing the border is to hide website, together The website of step channel, which also can guarantee that, receives the ACK message that an access point is sent.

After channel synchronization terminates, website, if not hearing any one complete frame, represents to be referred in synchronizing process Sending in time slot, which does not have other websites to cross the border, sends data.Website use is assigned the remaining time transmission data of time slot.Website is adopted Accessed with enhanced distributed channel（Enhanced DistributedChannel Access, referred to as：EDCA）Mode connect Enter channel.

After channel synchronization terminates, website, if having heard a complete frame, represents this time slot in synchronizing process（Now To be assigned time slot）Inside there are other websites to cross the border and send data.The website is not assigned time slot transmission data at this.Optionally, The website can be in dormancy this period.The website can be since back to back next time slot in access point monitors channel Carve, waking up for cycle receives time slot free time configured information, and the moment is to add maximum channel synchronization duration at the border moment ProbeDelay adds maximum back off time window（Max Backoff Window, referred to as, MBW）Time.

Optionally, in order to further improve channel utilization, after channel synchronization terminates, if website is pleasant to the ear in synchronizing process There is indicating bit to point out that the frame is last frame or is in response to last to a complete frame, and in the frame received Frame, website still can be continuing with this according to indicating bit information and be assigned time slot.

In synchronizing process, website may hear the data frame that website is sent to access point that crosses the border, if data frame MoreData units indicate that the frame is last data frame, and website is after this data frame end, then waits a confirmation to disappear After breath, begin to use channel.If the MoreData units of data frame indicate that the frame is not last data frame, the website is not In this time slot（It is now to be assigned time slot）Send data.

In synchronizing process, website may hear access point to the confirmation message for website transmission of crossing the border, if it is confirmed that in message Carry instruction confirmation message confirmation is the information of last data frame, and website is opened after this confirmation message terminates Beginning uses channel.If the website 3 in Fig. 5 can send data using the remaining time of the 3rd time slot in this case. If it is confirmed that do not have carrying instruction confirmation message confirmation in message is the information or confirmation message of last data frame What middle carrying indicated confirmation message confirmation is not the information of last data frame, and the website is not assigned time slot transmission at this Data.

Do not have on the first slot as shown in figure 5, website 1 occupies all the second time slot and the time slot of part the 3rd, website 1 Data have been sent, website 2 is waken up in the second time slot carries out channel synchronization, has monitored that message is transmitted on channel, and after The continuous access point monitors channel moment for also having data transfer, the then dormancy of website 2 to the 3rd time slot, access point from time slot it is initial when Start at quarter to monitor channel, the sending time slots free time configured information after time slot free time is judged, in sync period and website 2 after the competition phase Start to receive time slot free time configured information.Because access point not can determine that whether website 2 has a data upload, access point from the 3rd when Gap starts to monitor channel, and at least sends the idle instruction message of a time slot to website 2, if website 2 is still sent out without data Send, just can determine that website 2 is sent without data.Website 3 is waken up in the 3rd time slot carries out channel synchronization, has monitored that message exists Transmitted on channel, but there is no data transfer subsequently.After the end of the step, the mode for starting EDCA accesses channel, uses the 3rd time slot To send data.Because data are relatively more, therefore website 3 crosses the border and occupies the time of the time slot of part the 4th.Access point is from time slot Initial time starts to monitor channel, and website 3 sends data in the 3rd time slot and the 4th time slot, thus access point in the 3rd time slot and 4th time slot not sending time slots free time configured information, but in the 5th time slot sending time slots free time configured information, instruction website 2 is at this The remaining time of time slot sends data, if website 2 has data transmission, website 2 is sent using the time slot remaining time；If stand Point 2 is sent without data, and after this time slot, access point thinks that 2 no data of website need to send, and no longer sending time slots are idle Configured information is to website 2.

After access point determines that website has sent data or sent without data, access point can stop monitoring channel.

Fig. 6 is configured information sending method of the present invention, the schematic diagram of data transmission method for uplink embodiment three.It is assumed to be in figure every One website assigns a time slot, such as assigns the first time slot for the first website.As shown in fig. 6, website 1 does not have on the first slot Data are sent, website 1, which crosses the border, occupies all the second time slot and the time slot of part the 3rd, and what access point must be in RAW is each Individual boundary of time slot determines whether that the situation for transmission of crossing the border occurs.Access point can terminate according to the previous time slot in current time slots Before last data frame for receiving indicate whether to have data to send, come the transmission that determines whether to cross the border.If also data Send, be then determined with transmission of crossing the border, if it is not, judging without transmission of crossing the border.If the situation for transmission of crossing the border, access point is stood A configured information of crossing the border is sent, this time slot that instruction will start is unavailable.Just it is assigned to the station of this time slot After point is waken up, configured information of crossing the border is received.In order to ensure access point can send configured information of crossing the border at boundary of time slot, cross the border Website can suitably adjust the PPDU transmission time when closing on boundary of time slot transmission PPDU.Website 1 such as cross the border in the first time slot In last PPDU can apart from boundary of time slot also have short frame period SIFS plus ACK along with SIFS time before It is sent completely, and first in the second time slot PPDU at least can be sent after cross the border instruction message and SIFS.Such as Fig. 6 It is shown, there are the data for transmission of crossing the border at access point monitors to the second time slot and the 3rd boundary of time slot, access point is to website 2 and website 3 send configured information of crossing the border, and website 2 and website 3, which are waken up, receives configured information of crossing the border, and then without channel synchronization, continue Dormancy.Access point starts in the initial time of follow-up the 4th time slot that transmission data of crossing the border are not present, the 5th time slot, the 6th time slot Channel being monitored until Lag synchronization phase and the time of competition phase, if non-slotted channel is idle in this period, then it is assumed that time slot is idle, Then to website 2 and 3 sending time slots free time of website configured information, website 2 and website 3, which are waken up, receives root after time slot free time configured information Data are sent according to remaining time of the time slot free time configured information in the time slot.Due to the 5th time slot do not cross the border data send hair Raw, access point does not send configured information of crossing the border in the initial time of the 5th time slot, and the 5th time slot is assigned to website 5, website 5 Wake up and do not receive configured information of crossing the border, start channel synchronization and competition, then access channel and send data.
