Communication terminal is the terminal for supporting wlan network comprising but it is not limited to mobile phone, tablet computer, laptop.This certain reality
Apply the terminal of example, communication terminal is in same wlan network under the first equipment.In the present embodiment, in WLAN local area network
In, each communication terminal and the first equipment are established and are communicated to connect, and then are carried out data transmission.In order to avoid a certain communication terminal is frequent
Radio resource is occupied with the first equipment sending and receiving data, needs to be monitored each communication terminal, knows each communication terminal and first
The exchange data of equipment, therefore before monitoring each communication terminal communicated to connect with the foundation of the first equipment, wireless LAN communication
Method includes judging whether terminal is in promiscuous mode, if so, each communication terminal of communication connection is established in monitoring with the first equipment.
It is understood that promiscuous mode refers to that a machine can receive all data flows by it, regardless of its purpose
Whether address is the machine, i.e., when terminal is in promiscuous mode, at same WLAN, terminal can receive the first equipment and each
Data before communication terminal.
It should be noted that in the present embodiment, it is specific to monitor each communication terminal for establishing communication connection with the first equipment
It include: acquisition communication terminal and the data volume that the first equipment carries out data transmission；I.e. to the transmitted data amount of each communication terminal into
Row monitoring；Certainly the data volume that the data volume can be a certain communication terminal and the first equipment is currently carrying out data transmission,
For example, the data volume of communication terminal A and the first equipment current transmission；The data volume can also be each communication terminal and the first equipment
Historic transmission data volume；Such as communication terminal A, B, C be within today, the data volume transmitted before current time.In some realities
Apply in example, each communication terminal that monitoring establishes communication connection with the first equipment can also be to the access way of each communication terminal into
Row monitoring.Such as whether the access mechanism for judging that communication terminal accesses the first equipment is that request to send/allowed to send RTS/CTS connects
Enter mechanism, if so, carrying out next step S302.It is understood that RTS/CTS mechanism, connects at present for the selection in DCF agreement
Enter mechanism.Be initially for solving hidden node problem, its feature be before transmitting data communication terminal first send it is shorter
Request to send frame (Request-To-Send, RTS), the first equipment with allow send frame (Clear-To-Send, CTS) reply
Communication terminal achievees the purpose that reserve channel.When communication terminal has data latency transmission, it first sends a RTS frame to
One equipment, wherein containing total duration required for sending data and confirmation packet.When the first equipment receives RTS frame, it
A CTS frame is replied after the SIFS time, which is broadcast frame, for allowing communication terminal to be sent, and is notified in network
Every other communication terminal will do it the communication terminal in subscription time section and the data of the first equipment are transmitted.In all-network
After having received CTS frame, can according to wherein information update network allocation vector (Network Allocation Vector,
NAV), so that channel will not be attempted to access in the subscription time section.That is the transmission of data volume be successfully have exchanged RTS frame and
Start after CTS frame.As shown in figure 5, Fig. 5 is RTS frame format defined in current standard, it includes the controls of the frame of 2 byte lengths
(Frame Control), the duration (Duration) of 2 byte lengths, the reception address (RA) of 6 byte lengths, 6 byte lengths
Send the frame check sequence (FCS) of address (TA) and 4 byte lengths.As shown in fig. 6, Fig. 6 is the CTS frame lattice that current standard defines
Formula, the i.e. frame comprising 2 byte lengths control (Frame Control), the duration (Duration) of 2 byte lengths, 6 byte lengths
Reception address (RA) and 4 byte lengths frame check sequence (FCS).
S302, judge whether the historical data the number of transmissions of communication terminal and the first equipment is greater than the first preset threshold, such as
It is to turn S303, if not, terminating.
In the present embodiment, when access way of the terminal to each communication terminal is monitored, the history number of the present embodiment
It can be the number that communication terminal successfully exchanges with the first equipment RTS/CTS according to the number of transmissions, be also possible to communication terminal transmission
The number of RTS.
When transmitted data amount of the terminal to each communication terminal is monitored, historical data the number of transmissions is each communication terminal
The data transmission times successfully carried out data transmission before with the first equipment, at this time regardless of communication terminal accesses connecing for the first equipment
Entering mechanism is what；In step s 302, the data volume that acquisition communication terminal and the first equipment carry out data transmission, when the data
When amount is greater than the second preset threshold, judge whether the historical data the number of transmissions of communication terminal and the first equipment is greater than first and presets
Threshold value includes judging whether the corresponding historical data the number of transmissions of the data volume is greater than the first preset threshold, wherein first is default
Threshold value and the second preset threshold can have to be arranged by terminal, can be adjusted flexibly according to actual use situation.Such as it gets
The data volume that communication terminal A, B, C and the first equipment carry out data transmission before is respectively a, b, c, and the second preset threshold is x, false
If data volume a is greater than x, then when obtaining communication terminal A and the transmission of the first device data, the corresponding historical data transmission of data volume a
Number；The data volume of how many time data transmission is a before i.e., and then judges whether the historical data the number of transmissions is greater than first
Preset threshold, when historical data the number of transmissions is greater than the first preset threshold, i.e., communication terminal and the first equipment carry out data biography
Defeated data volume is excessive, and excessively frequently, show that the communication equipment frequently occupies radio resource so that other communication terminals with
The probability of first device data transmission is small, therefore need to transmit and interfere to the data of the communication terminal.
S303, request transmission message frame is generated.
It should be noted that existing between the first equipment and communication terminal in 802.11 wireless LAN technology of IEEE
One shared transmission channel, since the first equipment is merely able to receive data from communication terminal every time, when communication terminal with
When the historical data the number of transmissions of first equipment is greater than the first preset threshold, then show the frequent sending and receiving data of the first equipment, solely
Account for channel.In order to avoid the communication equipment monopolizes channel, need to interfere the data transmission of the communication terminal；In this reality
It applies in example, channel can be obtained to the first device request by terminal and be interfered, and then reached and limit the communication terminal network speed
Effect；Specifically, terminal generates RTS frame request channel.
S304, request transmission message frame is sent to the first equipment with request channel.
When present channel is busy state, i.e., when communication terminal and the first equipment are currently carrying out data transmission, eventually
End cannot send any data to the first equipment by channel；Therefore, RTS frame is being sent with request channel to the first equipment
Before, judge whether present channel is in a busy state, that is, judge whether communication terminal is currently being counted with the first equipment
According to transmission, if not, sending RTS frame to the first equipment with request channel.
It should be understood that terminal is sent RTS frame to the first equipment and is believed with request when present channel idle state
When road, according to the difference of terminal PRI, the number for sending RTS frame is also different.Specifically, sending RTS frame packet to the first equipment
The terminal PRI for obtaining communication terminal is included, judges whether the priority of communication terminal is greater than the priority of terminal, when communication is whole
When the priority at end is less than the priority of terminal, when the first equipment receives the RTS frame of communication terminal and terminal at the same time, first
Equipment can preferentially carry out data transmission with terminal according to terminal PRI；At this point, terminal only need to send a RTS to the first equipment
Frame is with request channel；When the priority of communication terminal be greater than terminal priority when, receive at the same time communication terminal and
When the RTS frame of terminal, the first equipment can preferentially carry out data transmission with communication terminal；When the first equipment is transferred with communication terminal
After data, in order to obtain channel, terminal sends RTS frame by the first predeterminated frequency to the first equipment and obtains the general of channel to increase
Rate.Wherein communication terminal, terminal priority can be by the setting of the first equipment, be also possible to go through according to first equipment
The setting of history data transmission times, such as historical data the number of transmissions is higher, terminal PRI is lower.In some embodiments,
