Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

In order to solve the problem that in a wireless local area network, when a communication terminal frequently transceives data with an access point and occupies a wireless local area network resource, which results in poor user experience, the present embodiment provides a wireless local area network communication method, fig. 3 is a basic flowchart of the wireless local area network communication method provided by the present embodiment, it should be understood that the wireless local area network communication method of the present embodiment is implemented based on IEEE 802.11, each step in the wireless local area network communication method may be executed by a terminal, the terminal may be any one of communication terminals in communication connection with a first device, as shown in fig. 4, the first device 401 establishes communication connection with the communication terminal 402, the communication terminal 403, and the communication terminal 404, and then the terminal may be any one of the communication terminal 402, the communication terminal 403, and the communication terminal 404. The wireless local area network communication method comprises the following steps:

s301, monitoring each communication terminal which establishes communication connection with the first equipment.

In this embodiment, the first device is an Access Point (AP) that provides a Wireless Local Area Network (WLAN) network, and specifically, the first device may be a router or a terminal; the communication terminal is a terminal supporting a WLAN network, which includes but is not limited to a mobile phone, a tablet computer, and a notebook computer. Of course, the terminal and the communication terminal of this embodiment are both in the same WLAN network under the first device. In this embodiment, in the WLAN, each communication terminal establishes a communication connection with the first device, and further performs data transmission. In order to avoid that a certain communication terminal frequently receives and transmits data with a first device to occupy wireless resources, each communication terminal needs to be monitored to acquire the communication data between each communication terminal and the first device, so that before each communication terminal establishing communication connection with the first device is monitored, the wireless local area network communication method comprises the step of judging whether the terminal is in a promiscuous mode, and if so, each communication terminal establishing communication connection with the first device is monitored. It is understood that promiscuous mode means that a machine is able to receive all the data streams passing through it, regardless of whether its destination address is that machine, i.e. when the terminal is in promiscuous mode, the terminal is able to receive data between the first device and the communication terminals under the same WLAN.

It should be noted that, in this embodiment, the monitoring of each communication terminal that establishes a communication connection with the first device specifically includes: acquiring the data volume of data transmission between a communication terminal and first equipment; namely, the transmission data volume of each communication terminal is monitored; of course, the data amount may be a data amount currently transmitted by a certain communication terminal and the first device, for example, a data amount currently transmitted by the communication terminal a and the first device; the data volume may also be a data volume of a historical transmission of each communication terminal with the first device; such as the amount of data communicated by the communication terminal A, B, C prior to the current time of day. In some embodiments, monitoring each communication terminal that establishes a communication connection with the first device may also be monitoring an access manner of each communication terminal. For example, it is determined whether the access mechanism of the communication terminal accessing the first device is the RTS/CTS access request/clear to send mechanism, if yes, the next step S302 is performed. It will be appreciated that the RTS/CTS mechanism is currently the access mechanism of choice in the DCF protocol. The first method is To solve the hidden node problem, and is characterized in that a communication terminal sends a short Request-To-Send (RTS) frame before sending data, and a first device replies To the communication terminal with a Clear-To-Send (CTS) frame To reserve a channel. When a communication terminal has data to send, it first sends an RTS frame to a first device, which includes the total duration needed to send the data and acknowledgement packets. When the first device receives the RTS frame, it replies a CTS frame after SIFS time, which is a broadcast frame for allowing the communication terminal to transmit and notifying all other communication terminals in the network that data transmission between the communication terminal and the first device will be performed within a reserved time period. After receiving the CTS frame, all networks can update their Network Allocation Vectors (NAVs) according to the information, so that they will not attempt to access the channel during the reserved time period. I.e. the transmission of the amount of data is started after the RTS frame and the CTS frame have been successfully exchanged. As shown in fig. 5, fig. 5 is a Frame format of RTS defined in the current standard, which includes a Frame Control (Frame Control) with a length of 2 bytes, a Duration (Duration) with a length of 2 bytes, a Receiving Address (RA) with a length of 6 bytes, a sending address (TA) with a length of 6 bytes, and a Frame Check Sequence (FCS) with a length of 4 bytes. As shown in fig. 6, fig. 6 shows the CTS Frame format defined by the current standard, i.e. the CTS Frame format includes a Frame Control (Frame Control) with a length of 2 bytes, a Duration (Duration) with a length of 2 bytes, a Receiving Address (RA) with a length of 6 bytes, and a Frame Check Sequence (FCS) with a length of 4 bytes.

S302, judging whether the transmission times of the historical data of the communication terminal and the first equipment are larger than a first preset threshold value or not, if so, turning to S303, and if not, ending.

In this embodiment, when the terminal monitors the access mode of each communication terminal, the number of times of transmitting the history data in this embodiment may be the number of times that the communication terminal and the first device successfully exchange RTS/CTS, or the number of times that the communication terminal sends RTS.

When a terminal monitors the transmission data amount of each communication terminal, the historical data transmission times are the data transmission times of the successful data transmission between each communication terminal and the first equipment, and at the moment, no matter what the access mechanism of the communication terminal to the first equipment is; in step S302, a data amount of data transmission between the communication terminal and the first device is obtained, and when the data amount is greater than a second preset threshold, determining whether the number of times of transmission of the historical data between the communication terminal and the first device is greater than a first preset threshold includes determining whether the number of times of transmission of the historical data corresponding to the data amount is greater than the first preset threshold, where the first preset threshold and the second preset threshold may be set by the terminal, and may be flexibly adjusted according to an actual use condition. For example, if the data amount obtained before the data transmission between the communication terminal A, B, C and the first device is a, b, and c, respectively, and the second preset threshold is x, and if the data amount a is greater than x, the historical data transmission frequency corresponding to the data amount a is obtained when the data transmission between the communication terminal a and the first device is performed; the method comprises the steps that a data volume of data transmission for a plurality of times is a, whether the historical data transmission times is larger than a first preset threshold value or not is further judged, and when the historical data transmission times is larger than the first preset threshold value, the data volume of data transmission between a communication terminal and first equipment is too large and too frequent, the communication equipment frequently occupies wireless resources, the probability of data transmission between other communication terminals and the first equipment is small, and therefore the data transmission of the communication terminal needs to be interfered.

S303, generating a request sending message frame.

It should be noted that, in the IEEE 802.11 wireless local area network technology, there is a shared transmission channel between the first device and the communication terminal, and since the first device can only receive data from one communication terminal at a time, when the number of times of transmission of the historical data between the communication terminal and the first device is greater than a first preset threshold, it indicates that the first device frequently receives and transmits data, and the channel is exclusively occupied. In order to avoid the communication device monopolizing the channel, the data transmission of the communication terminal needs to be interfered; in this embodiment, the terminal may request the first device to acquire a channel for interference, so as to achieve the effect of limiting the network speed of the communication terminal; specifically, the terminal generates an RTS frame to request acquisition of a channel.

S304, sending a request sending message frame to the first equipment to request to acquire the channel.

When the current channel is in a busy state, namely when the communication terminal and the first equipment are currently carrying out data transmission, the terminal cannot send any data to the first equipment through the channel; therefore, before sending an RTS frame to the first device to request to acquire the channel, it is determined whether the current channel is in a busy state, that is, whether data transmission is currently being performed between the communication terminal and the first device, and if not, the RTS frame is sent to the first device to request to acquire the channel.

It should be understood that, when the terminal sends an RTS frame to the first device to request to acquire a channel when the current channel is in the idle state, the number of times the RTS frame is sent is different according to the priority of the terminal. Specifically, sending the RTS frame to the first device includes acquiring a terminal priority of the communication terminal, and determining whether the priority of the communication terminal is greater than the priority of the terminal, where when the priority of the communication terminal is less than the priority of the terminal, and the first device receives the RTS frames of the communication terminal and the terminal at the same time, the first device performs data transmission with the terminal according to the priority of the terminal; at this time, the terminal only needs to send an RTS frame to the first device once to request to acquire a channel; when the priority of the communication terminal is higher than that of the terminal, when RTS frames of the communication terminal and the terminal are received at the same time, the first equipment can preferentially perform data transmission with the communication terminal; after the first device and the communication terminal finish data transmission, in order to acquire the channel, the terminal sends an RTS frame to the first device according to a first preset frequency so as to increase the probability of acquiring the channel. The priority of the communication terminal and the terminal may be set by the first device, or may be set according to the number of transmission times of the historical data with the first device, for example, the higher the number of transmission times of the historical data is, the lower the priority of the terminal is. In some embodiments, when the priority of the communication terminal is equal to that of the terminal, or the communication terminal and the terminal have no terminal priority, the terminal may send an RTS frame at a first preset frequency to increase the probability of acquiring a channel, and at this time, the first device may broadcast and send a CTS frame corresponding to the time sequence of receiving the RTS frame; or according to the number of the received RTS frames in the preset time period, broadcasting and sending the corresponding CTS frames.

In this embodiment, after sending an RTS frame to a first device to request to acquire a channel, it may further be determined whether a CTS frame corresponding to the RTS frame sent by the first device is received in a preset time period, if so, it indicates that the terminal has acquired the channel, and if not, the terminal sends the RTS frame at a second preset frequency, where the preset time period may be after a short interframe space (SIFS); when the priority of the communication terminal is greater than the priority of the terminal, the second preset frequency may be equal to the first preset frequency; and when the priority of the communication terminal is greater than that of the terminal, the second preset frequency is greater than the first preset frequency.

The embodiment provides a wireless local area network communication method, which is realized based on IEEE 802.11, and each step in the method is realized by a terminal, when the terminal is in a promiscuous mode, the terminal monitors each communication terminal establishing communication connection with first equipment, and when the transmission times of historical data of a certain communication terminal and the first equipment are greater than a first preset threshold value, the communication terminal is indicated to frequently receive and transmit data and frequently occupy a channel; at the moment, the terminal generates an RTS frame and sends the RTS frame to the first device to request to acquire the channel, and because the first device can only carry out data transmission with one communication terminal each time, when the terminal successfully acquires the channel, the communication terminal which frequently receives and transmits data can not occupy the channel at the moment. Therefore, in this embodiment, the terminal and the first device successfully exchange the RTS frame/CTS frame to interfere with the communication terminal, so as to achieve the effect of limiting the network speed of the communication terminal within a certain period, avoid that a certain communication terminal frequently receives and transmits data to monopolize wireless resources, and improve the satisfaction of the user.

Second embodiment

To facilitate understanding of the present invention, this embodiment is described with a more specific example, as shown in fig. 7, fig. 7 is a flowchart of a wlan communication method according to a second embodiment of the present invention, where the wlan communication method includes:

and S701, judging whether the terminal is in the promiscuous mode, if so, turning to S702, and if not, ending.

In this embodiment, the terminal may be any one of communication terminals that establish a communication connection with the first device, where both the terminal and the communication terminal are in the same WLAN network under the first device, and when the terminal is in the promiscuous mode, the terminal can receive data before the first device and each communication terminal under the same WLAN.

S702, the terminal monitors each communication terminal which establishes communication connection with the first equipment.

Because the terminal is in the promiscuous mode, the terminal can acquire previous data between each communication terminal and the first equipment, and further can monitor an access mechanism of each communication terminal accessing the first equipment; when the previous data between the communication terminal and the first device includes an RTS frame and a CTS frame, it indicates that the access mechanism of the communication terminal accessing the first device is an RTS/CTS access mechanism.

And S703, judging whether the times of successfully exchanging the RTS/CTS between each communication terminal and the first equipment is greater than a first preset threshold value, if so, turning to S704, and if not, ending.

It is understood that, when the communication terminal successfully exchanges RTS/CTS with the first device before, it indicates that the communication terminal and the first device have successfully transmitted data, and when the number of times of successfully exchanging RTS/CTS is greater than the first preset threshold, it indicates that the communication terminal frequently transmits data with the first device. Since the first device can perform data transmission with the communication terminal only through one channel, that is, can receive data from only one communication terminal at a time, when the communication terminal frequently receives and transmits data, the channel is frequently occupied, and therefore, the data transmission of the communication terminal needs to be interfered, and the next step S704 is further performed.

S704, the terminal generates an RTS frame.

It can be understood that, the terminal sends a short RTS frame before sending data, and the first device replies to the terminal with a CTS frame to achieve the purpose of reserving a channel; the RTS Frame is in an RTS Frame format defined in the standard, that is, includes a Frame Control (Frame Control) having a length of 2 bytes, a Duration (Duration) having a length of 2 bytes, a Receiving Address (RA) having a length of 6 bytes, a Transmitting Address (TA) having a length of 6 bytes, and a Frame Check Sequence (FCS) having a length of 4 bytes.

S705, acquiring the terminal priority of the communication terminal, and sending the RTS frame to the first device according to the terminal priority of the communication device.

In this embodiment, it is assumed that both the terminal and the communication terminal have a terminal priority, and the terminal priority is set by the first device, and sending the RTS frame to the first device according to the terminal priority of the communication device specifically includes that when the priority of the communication terminal is smaller than the priority of the terminal, and the first device receives the RTS frames of the communication terminal and the terminal at the same time, the first device performs data transmission with the terminal according to the terminal priority; at this time, the terminal only needs to send an RTS frame to the first device once to request to acquire a channel; when the priority of the communication terminal is higher than that of the terminal, when RTS frames of the communication terminal and the terminal are received at the same time, the first equipment can preferentially perform data transmission with the communication terminal; after the first device and the communication terminal finish data transmission, in order to acquire the channel, the terminal sends an RTS frame to the first device according to a first preset frequency so as to increase the probability of acquiring the channel. When the terminal accesses to the CTS frame corresponding to the RTS frame sent by the first device, it indicates that the terminal has acquired the channel, and at this time, the communication terminal cannot perform data transmission with the first device any more.

For convenience of understanding, this embodiment describes a wireless local area network communication method by using a specific example, after the terminal starts the promiscuous mode, the number of times of successfully exchanging RTS/CTS frames between which communication terminal and the first device is detected to be large, and when the number of times exceeds a first preset threshold, the RTS frame is sent according to the priority of the communication terminal and the terminal, so as to interfere data transmission of the communication terminal, avoid that a certain communication terminal frequently receives and sends data to occupy wireless resources, and improve the satisfaction degree of the user.

Third embodiment

The present embodiment provides a wireless local area network communication method, as shown in fig. 8, the wireless local area network communication method includes:

s801, acquiring the data volume of data transmission between the communication terminal and the first device.

In this embodiment, the data amount is a data amount of historical transmission between each communication terminal and the first device, that is, a previous data amount between each communication terminal and the first device, and then it is determined whether the data amount is greater than a second preset threshold, and when the data amount is greater than the second preset threshold, a bandwidth allocated by the communication terminal corresponding to the data amount is larger.

And S802, when the data volume is larger than a second preset threshold, judging whether the transmission times of the historical data corresponding to the data volume are larger than a first preset threshold, if so, turning to S803, and if not, ending.

And judging the historical data transmission times of the data volume pair, and judging whether the communication terminal frequently transmits the data volume with the first device or not according to the judgment result, wherein the historical data transmission times are the data transmission times of the communication terminal successfully transmitting the data before the communication terminal and the first device, and at the moment, the access mechanism of the communication terminal accessing the first device is not the same.

S803, an RTS frame is generated.

The data volume of the data transmission between the communication terminal and the first device is too large and too frequent, which indicates that the communication device frequently occupies wireless resources, so that the probability of data transmission between other communication terminals and the first device is small, and therefore the data transmission of the communication terminal needs to be interfered.

And S804, when the current channel is idle, sending an RTS frame to the first equipment.

When the current channel is in a busy state, that is, when the communication terminal and the first device are currently performing data transmission, the terminal cannot send any data to the first device through the channel, and therefore, when the current channel is idle, an RTS frame is sent to the first device.

S805, determining whether a CTS frame corresponding to the RTS frame sent by the first device is received in a preset time period, if so, ending, otherwise, going to S806.

In this embodiment, it is assumed that, when the terminal and each communication terminal have no terminal priority, after the terminal may send an RTS frame to the first device once, and when a CTS frame corresponding to the RTS frame sent by the first device is received after a preset time period, it indicates that the terminal has reserved a channel, and then the communication terminal that frequently receives and transmits data cannot perform data transmission with the first device, so as to reach the limitation on the network speed of the communication terminal.

And S806, sending the RTS frame according to a second preset frequency.

When the CTS frame corresponding to the RTS frame is not received within the preset time period, it indicates that the terminal has failed to reserve the channel, and at this time, the terminal may generate the RTS frame at the second preset frequency to increase the probability of acquiring the channel thereafter.

The embodiment provides a wireless local area network communication method, which includes acquiring a data volume of data transmission between each communication terminal and a first device, generating an RTS frame when the data volume is greater than a second preset threshold and a historical data transmission frequency corresponding to the data volume is greater than a first preset threshold, and sending the RTS frame to the first device to request to acquire a channel when a current channel is idle, so as to interfere a communication terminal which frequently receives and transmits data and limit the communication terminal and the first device from performing data transmission.

In this embodiment, the processor 901 may further implement determining whether the terminal is in the promiscuous mode, for example, monitoring each communication terminal that establishes a communication connection with the first device, where monitoring each communication terminal that establishes a communication connection with the first device includes: acquiring the data volume of data transmission between a communication terminal and first equipment; when the data volume is greater than a second preset threshold, at this time, judging whether the transmission times of the historical data between the communication terminal and the first device are greater than a first preset threshold includes: and judging whether the transmission times of the historical data corresponding to the data volume are greater than a first preset threshold value or not. Of course, monitoring each communication terminal establishing a communication connection with the first device may also be to determine whether an access mechanism of the communication terminal accessing the first device is a request to send/clear to send RTS/CTS access mechanism, and if so, then determine whether the number of times of transmission of the historical data of the communication terminal and the first device is greater than a first preset threshold, where the number of times of transmission of the historical data may be the number of times of sending a request to send message frame, or the number of times of successful exchange of the request to send message frame/clear to send frame.

Of course, before sending the request-to-send message frame to the first device to request to acquire the channel, the processor 901 may further implement determining whether a certain communication terminal and the first device are currently performing data transmission, and if not, sending the request-to-send message frame to the first device to request to acquire the channel, where sending the request-to-send message frame to the first device to request to acquire the channel includes: acquiring a terminal priority of a communication terminal; when the priority of the communication terminal is smaller than that of the terminal, sending a request sending message frame to the first equipment to request to acquire a channel; and when the priority of the communication terminal is greater than that of the terminal, sending a request sending message frame to the first equipment according to a first preset frequency to request to acquire a channel. Of course, after the request sending message frame is sent to the first device to request to acquire the channel, it may also be determined whether the transmission permission frame corresponding to the request sending frame sent by the first device is received in a preset time period, and if not, the request sending message frame is sent according to the second preset frequency.
