Fig. 5 is a kind of flow chart of data transmission method shown according to an exemplary embodiment.The embodiment of the present disclosure with Terminal and AP are interacted, and the data transmission method provided the embodiment of the present disclosure is illustrated.In conjunction with Fig. 5, for the ease of saying Bright, the embodiment of the present disclosure includes terminal A and terminal B with implementation environment shown in FIG. 1, and when AP transmits data to AP to terminal A Priority be adjusted for, to the embodiment of the present disclosure provide data transmission method be explained.As shown in figure 5, The data transmission method that the embodiment of the present disclosure provides includes the following steps.

In step S501, when the transfer resource that terminal A detects that AP is provided is in busy state, terminal A is detected From in AP transmit data when the bit error rate.

When the transfer resource that AP is provided is in busy state, illustrate that AP offer is used in current time other terminals Transfer resource.At this point, terminal A needs to wait DIFS, and after continuing waiting for Random Waiting Time, the transfer resource is detected again Whether it is in idle condition, until transmitting data to AP when detecting that transfer resource is in idle condition.In the embodiment of the present disclosure In, when terminal A detects that transfer resource is in busy state, terminal A can detecte terminal A certainly during waiting Bit error rate when in transmission data, thus the step of triggering following is adjusted the Random Waiting Time of terminal A.

Illustratively, terminal A detection from transmit data to AP when the bit error rate when, including but not limited to by as follows Step S5011 is realized to step S5013：

In step S5011, terminal A obtains the data transmission frequency that data are sent to AP.

Wherein, terminal A, to the number of the AP data packet sent, can be obtained and be sent to AP according within the unit time The data transmission frequency of data.For example, terminal A is sent out to AP if terminal A had sent 500 data packets to AP in 10 seconds The data transmission frequency for sending data is 50/second.

In step S5012, terminal A obtains the data receiver frequency that AP receives terminal data.

Illustratively, it can be determined and be received eventually by the number of the received data packet come self terminal A in the AP statistical unit time The data of end A data connect frequency.For example, if AP receives 400 data packets from terminal A in 10 seconds, AP can be with Determine that the data receiver frequency for receiving terminal A data is 40/second.

On this basis, terminal A can send number to AP when obtaining the data receiver frequency of AP reception terminal A data It is requested according to frequency acquisition is received, the mark of the data receiver frequency carried terminal, such as MAC (the Media Access of terminal A Control, media access control) (International Mobile Equipment Identity is moved by address or IMEI Dynamic equipment international identity code)；After AP receives data receiver frequency acquisition request, the data of terminal A are obtained according to terminal iidentification Frequency is received, and frequency is received to terminal A returned data according to terminal iidentification.

In step S5013, terminal A determines terminal A from transmission according to data transmission frequency and data receiver frequency Bit error rate when data.

Wherein, terminal A can determine the ratio between data receiver frequency and data transmission frequency, by data receiver frequency The difference between ratio and 1 between data transmission frequency is as the bit error rate.For example, if data transmission frequency be 50/ Second, data receiver frequency is 40/second, then terminal A can determine that its bit error rate is 1-40/50=0.2.

As shown in fig. 6, the software hierarchy framework is based on shown in FIG. 1 it illustrates a kind of software hierarchy configuration diagram Implementation environment schematic diagram obtains.As shown in fig. 6, the common application module in terminal is used for the common application module of network side just Normal open letter, multiple Special controlling modules are used to cooperate the intelligence of Special controlling module and other Implement of Function Module networks in AP Dynamic control.Wherein, terminal A detection to AP transmit data when the bit error rate when, the spy in terminal A can be passed through Different control module is realized.

In step S502, the bit error rate is sent to AP by terminal A.

Wherein, terminal A can carry the bit error rate in the communication message between AP when the bit error rate is sent to AP It sends.

It should be noted that above content only with terminal A determine to AP transmit data when the bit error rate and will The process that the bit error rate is sent to AP is illustrated.However, transmitting number to AP to which terminal in network to determine AP According to when priority be adjusted, be connected to AP each terminal be both needed to execute above-mentioned steps S501 and step S502.In conjunction with figure 5, terminal B should also execute above-mentioned steps S501 and step S502.

In step S503, after AP receives the correspondence bit error rate for each terminal transmission that connection has been established, according to each end The bit error rate at end, the terminal for determining that the bit error rate is not less than preset threshold is terminal A.

When the bit error rate of any terminal is not less than preset threshold, it can determine that the current signal of the terminal is poor, when When improving priority of the terminal to AP transmission data, it can be ensured that the terminal of signal difference can also get a constant speed of AP offer The service of degree.Therefore, the embodiment of the present disclosure adjustment bit error rate is excellent when transmitting data to AP not less than the terminal of preset threshold First grade.At this point, AP is it needs to be determined that the bit error rate of which terminal is not less than preset threshold.In the embodiments of the present disclosure, with the bit error rate Terminal not less than preset threshold is illustrated for being terminal A.

About the specific value of preset threshold, the embodiment of the present disclosure is not especially limited, when it is implemented, can be according to need It sets.For example, preset threshold can be 0.4,0.5 etc..

In step S504, AP sends priority adjustment instruction to terminal A, wherein priority adjustment instruction is used to indicate Random Waiting Time is adjusted to specified duration by terminal A, to improve priority of the terminal A when transmitting data to AP.

Implementation environment as shown in connection with fig. 1, the communication protocol between terminal and AP, as defined random waiting in 802.11 The range of time.In the embodiments of the present disclosure, by the range of Random Waiting Time defined by communication protocol be defined as with reference to Machine waiting time range.Due to the shorter terminal of Random Waiting Time when transmitting data to AP priority with higher, because This, when specified in the embodiment of the present disclosure a length of smaller value with reference in Random Waiting Time range.For example, when with reference to random etc. When time range is 0.5 second to 1 second, specified duration can be 0.6 second etc..

In step S505, terminal A is adjusted to specified duration according to priority adjustment instruction, by Random Waiting Time.

Wherein, terminal A is according to priority adjustment instruction, when Random Waiting Time is adjusted to specified duration, including but not The following two kinds mode is limited by realize：

First way：Specified duration is determined by AP, and the specified duration that AP is determined is carried in priority adjustment instruction.This When, terminal A is adjusted to specified duration according to the specified duration carried in priority adjustment instruction, by Random Waiting Time.

Under this kind of mode, specified time is carried in priority adjustment instruction, AP refers to terminal A transmission priority adjustment When enabling, need first to determine the corresponding specified duration of terminal A.The mode of the corresponding specified duration of terminal A, Ke Yiyou are determined about AP It is a variety of.For example, AP can first from reference Random Waiting Time range select a target Random Waiting Time range, and from A value is randomly choosed within the scope of the target Random Waiting Time is used as the corresponding specified duration of terminal A.

Wherein, the initial time of target Random Waiting Time range is the initial time with reference to Random Waiting Time range, And target Random Waiting Time range accounts for the designated ratio with reference to Random Waiting Time range.Specific number about designated ratio Value, the embodiment of the present disclosure are not especially limited.For example, the designated ratio can be half, one third etc..For example, working as Designated ratio is half, and with reference to Random Waiting Time range be 0.5 second to 1 second when, target Random Waiting Time range It is 0.5 second to 0.75 second.

In another embodiment, the bit error rate determined in step S503 as AP is not less than the terminal quantity of preset threshold When having multiple, clashed when transmitting data to AP not less than the terminal of preset threshold in order to avoid these bit error rates, AP should Each terminal for the bit error rate not less than preset threshold determines different specified durations.

Illustratively, when the bit error rate is multiple not less than the quantity of the terminal of preset threshold, AP can be according to each terminal It is presently in the type of service of reason, determines the corresponding specified duration of each terminal.

Such as, be specified duration that the relatively high terminal of requirement of real-time determines for currently processed type of service, less than for Currently processed type of service is the specified duration that the not high terminal of requirement of real-time determines.For example, if terminal A and terminal C It is the terminal that the bit error rate is not less than preset threshold, terminal A is currently carrying out video traffic, and terminal C is currently carrying out language Sound business, since the real-time of video traffic is higher than the real-time of voice service, can for the terminal A specified duration determined To be less than the specified duration determined for terminal C.

The second way：Terminal A receive priority adjustment instruction after, according to priority adjustment instruction from it is preset with reference to A specified duration is determined in machine waiting time range；Then, when Random Waiting Time is adjusted to determining specified by terminal A It is long.

Wherein, it can be any value in target Random Waiting Time range that terminal A, which is the specified duration that oneself is determined,.It closes It has been illustrated in foregoing in the content of target Random Waiting Time range, details are not described herein again.

Definition based on target Random Waiting Time can obtain, and target Random Waiting Time range is with reference to Random Waiting Time A lesser range of numerical value in range, by the way that the Random Waiting Time of terminal A is adjusted to target Random Waiting Time model Specified duration in enclosing, it can be ensured that the Random Waiting Time that terminal A is obtained is the communications protocol met between AP and terminal One, compared with fractional value, to realize on the basis of meeting communication protocol, is improved priority when terminal A transmits data to AP.

In step S506, if since terminal A detecting that transfer resource is in busy state, wait DIFS and refer to It after timing is long, detects that transfer resource is in idle condition, then transmits data to AP.

Wherein, DIFS is fixed duration, and each terminal is required to elder generation when detecting that transfer resource is in busy state After waiting DIFS, then wait Random Waiting Time.In the embodiment of the present disclosure, each end of preset threshold is not less than for the bit error rate End, when detecting that transfer resource is in busy state, is required to first wait DIFS, then wait corresponding specified duration；It is right It is required to first wait when detecting that transfer resource is in busy state in each terminal that the bit error rate is less than preset threshold DIFS, then wait with reference to a Random Waiting Time within the scope of Random Waiting Time.

In addition, if since terminal A detecting that transfer resource is in busy state, wait DIFS and specified duration Afterwards, detect transfer resource still in busy state, then after terminal A needs to continue waiting for the sum of DIFS and specified duration, Whether detection transfer resource is in idle condition again.And so on, until terminal A detects that transfer resource is in idle condition When, data are transmitted to AP by the transfer resource.
