Detailed Description
As shown in fig. 1, a method for controlling optimization of a multi-terminal access wireless network includes the steps of:
s200: and acquiring the time consumption required by each terminal for transmitting data through each wireless network access device.
The terminal is a terminal device that can be accessed to a wireless network in a wired or wireless manner, and specifically, the terminal device may be a smart phone, a tablet computer, a palm computer, a smart television, or the like. The wireless network access device is a device, such as a router (large router) or a base station, that is connected to a terminal, and that transmits data uploaded by the terminal to a wireless network (internet or local area network) and transmits data transmitted by the wireless network to the terminal. In step S200, the time consumption required for each terminal to transmit data through each wireless network access device is obtained, and the time consumption required for different terminals to transmit data through different wireless network access devices is generally different due to different signal transmission environments (distance, noise environment, etc.) between the terminals and the wireless network access devices. The acquisition may be performed by real-time measurement + calculation, or may be performed by obtaining time consumption required for each terminal to transmit data through each wireless network access device from historical empirical data. Specifically, it may be time-consuming to apply a private communication mechanism to acquire data transmission of each terminal through each wireless network access device, where the private communication mechanism is a manner different from a wireless network existing in a current wireless network environment, for example, when the current wireless network environment is a Wi-Fi network, the private communication protocol may be implemented by a 433MHz communication module, may also be implemented by a 2.4GHz communication module, and may also be implemented by a 3G/4G cellular mobile network.
In one embodiment, step S200 specifically includes:
the method comprises the following steps: and acquiring the signal connection strength between each terminal and each wireless network access device.
The signal connection strength between the terminal and the wireless network access device can be acquired and tested by using the existing instrument device, such as a common network optimization and network regulation device. Optionally, the obtained data may be recorded and characterized in a table or data matrix manner, and when a matrix is adopted, the wireless network access device may be recorded in rows, and the terminal may be recorded in columns, so as to finally construct a signal strength matrix.
Step two: and calculating the time consumed for each terminal to transmit data through each wireless network access device according to the signal connection strength between each terminal and each wireless network access device.
And calculating the time consumed for each terminal to transmit data through each wireless network access device based on the signal connection strength between each terminal and each wireless network access device obtained in the step one. In particular, this calculation process needs to be determined with reference to the communication tasks corresponding to the respective terminals. Furthermore, the signal strength matrix obtained in the first step can be converted into a communication time consumption matrix. It should be noted that, for a terminal and a wireless network access device, data may not be transmitted between the terminal and the wireless network access device, and at this time, the time required for the terminal to transmit data through the wireless network access device is infinite.
S400: and matching each terminal with the communication channel in each wireless network access device according to the principle of minimum required time consumption and the principle that a single communication channel in a single wireless network access device only allows access to a single terminal.
And step S200, when the time consumption for each terminal to transmit data through each wireless network access device is obtained, and each terminal is paired with the communication channel in each wireless network access device based on the principle that only a single terminal is allowed to be accessed according to the minimum time consumption principle required and a single communication channel in the single wireless network access device. Generally, a single wireless network access device has multiple communication channels, for example, some base stations have 3 communication channels, some large routers have dozens of network line interfaces, and the like. Since a single communication channel of a single wireless network access device can only support a single terminal to transmit data at the same time under normal conditions (without frequency division or code division processing), when the terminal and the wireless network access device are performed, only a single terminal principle is allowed to be accessed by the single communication channel of the single wireless network access device. In addition, as the multi-terminal efficient access to the wireless network needs to be realized, a pairing scheme with small time consumption for data transmission needs to be selected as much as possible according to the minimum time consumption principle.
S600: when the unpaired terminal exists, the wireless network access equipment is selected according to the minimum time-consuming principle required for transmitting data between the unpaired terminal and the wireless network access equipment, and the unpaired terminal is paired with the communication channel in the wireless network access equipment according to the minimum time-consuming principle required for bearing tasks in the communication channel in the wireless network access equipment.
As described above, a single channel in a single wireless network access device can only support a single terminal to transmit data at the same time, so that an unpaired terminal exists after the allocation in step S400, and when such a terminal exists, secondary pairing is required, wherein the secondary pairing requires selecting the wireless network access device according to the minimum time consumption principle required for data transmission between the unpaired terminal and the wireless network access device, and pairing the unpaired terminal and the communication channel in the wireless network access device according to the minimum time consumption principle required for a loaded task in the communication channel in the wireless network access device. Specifically, the secondary pairing process is divided into two stages, one stage is to select a suitable wireless network access device for a single terminal, and the selection principle is that the time consumption required for data transmission between the terminal and the wireless network access device is the minimum, for example, the time consumption required for data transmission between the existing tablet computer a, the existing base station X, the existing base station Y, and the existing base station Z is 1 second, 2 seconds, and 3 seconds respectively. The first stage controls the tablet a to pair with the base station X. And in the second stage, selecting a proper communication channel in the selected wireless network access equipment. The selection is based on the principle that it takes a minimum time to perform the tasks already carried in the communication channel of the radio network access device. Continuing with the above example, assuming that there are No. 1 communication channel, No. 2 communication channel and No. 3 communication channel in the base station X, after the processing in step S400, the No. 1 communication channel carries a task of data transmission for 2 seconds, the No. 2 communication channel carries a task of data transmission for 3 seconds, and the No. 3 communication channel carries a task of data transmission for 1 second, then the tablet computer a is selected to be paired with the No. 3 communication channel in the base station X, that is, the tablet computer a is arranged to transmit data (access to the wireless network) through the No. 3 communication channel in the base station X.
The invention relates to a multi-terminal access wireless network optimization control method, which comprises the steps of obtaining time consumption required by each terminal for transmitting data through each wireless network access device, pairing each terminal with a communication channel in each wireless network access device according to a minimum time consumption principle required and a principle that a single communication channel in the single wireless network access device only allows access to a single terminal, selecting the wireless network access device according to the minimum time consumption principle required by data transmission between the unpaired terminal and the wireless network access device when the unpaired terminal exists, and pairing the unpaired terminal with the communication channel in the wireless network access device according to the minimum time consumption principle required by a loaded task in the communication channel in the wireless network access device. In the whole process, based on the principle that the time required for the terminal to transmit data through the wireless network access equipment is the minimum, the terminal and the wireless network access equipment are reasonably paired, the overall time consumption of communication between a plurality of terminals and a plurality of wireless network optimization equipment is finally effectively reduced, the wireless network blockage caused by the fact that a plurality of terminals access the wireless network is avoided, and the data transmission efficiency of the terminal through the wireless network is improved.
As shown in fig. 2, in one embodiment, step S400 further includes:
s300: and identifying a terminal which can only communicate with a single wireless network access device in each terminal, and pairing the identified terminal with the corresponding wireless network access device.
In some cases there may be a terminal that can only communicate through a single wireless network access device, i.e., for the terminal, the wireless network access device that is capable of communicating is its only paired wireless network access device. For this particular case, the terminal is preferably paired with a corresponding unique communication-capable wireless network access device. Optionally, when a wireless network access device is the only wireless network access device capable of communicating of multiple terminals, the multiple terminals may be allocated in different communication channels of the wireless network access device. In the following specific application examples, the special case will be further exemplified.
As shown in fig. 2, in one embodiment, after step S600, the method further includes:
s700: and balancing the paired terminals of different communication channels in the same wireless network access equipment.
Specifically, step S700 includes: acquiring time consumption required by tasks corresponding to terminals which are paired with different communication channels in the same wireless network access device; calculating the difference value between the consumed time of the tasks corresponding to the terminals which are paired with the different communication channels, and recording the difference value as the difference value; judging whether the number of the paired terminals of the communication channel with the largest consumed time is multiple or not; when the number of the terminals which are paired with the communication channel which needs the largest consumed time is multiple and the difference is larger than the consumed time needed by the task corresponding to the terminal which consumes the relatively smaller time in the terminals which are paired with the communication channel which needs the largest consumed time, the terminal which consumes the relatively smaller time in the terminals which are paired with the communication channel which needs the largest consumed time is adjusted to the communication channel which needs the smallest consumed time.
Optionally, there may be imbalance between the paired terminals in the internal communication channel of the single wireless network access device after the secondary pairing in step S600, for example, a certain wireless network access device has 3 communication channels, a communication channel 1 carries 1 communication task, the required time consumption is 4 seconds, a communication channel 2 carries 2 communication tasks, the required time consumption is 7 seconds, the 2 communication tasks are respectively a task 1 which requires 5 seconds and a task 2 which requires 2 seconds, the communication channel 3 carries 1 communication task, the required time consumption is 3 seconds, the terminal balance of the paired terminals of different communication channels in the wireless network access device is performed, the balance aims to balance the time consumption of the tasks carried by different communication channels in the same wireless network access device as much as possible, namely, the task 2 which takes 2 seconds in the communication channel 2 is balanced and adjusted to the communication channel 3.
As shown in fig. 2, in one embodiment, after step S700, the method further includes:
s820: when the paired terminals of different communication channels in the wireless network access equipment cannot be balanced, the paired terminals of the communication channels which cannot be balanced are identified and recorded as the residual terminals.
After the internal communication conduction equalization for the wireless network access devices in step S700, the equalization is performed again between different wireless network access devices, and the equalization process can be understood as equalization between one cross-wireless network access device. Firstly, when the paired terminals of different communication channels in the wireless network access equipment cannot be balanced, the paired terminals of the communication channels which cannot be balanced are identified. For example, when a certain wireless network access device includes a number 1 communication channel, and carries 1 task that needs to take 10 seconds, a number 2 communication channel carries 1 task that needs to take 10 seconds, and a number 3 communication channel carries 2 tasks that respectively need to take 1 second and 10 seconds, step S700 balances paired terminals between different communication channels of the wireless network access device for the terminal, paired terminals of different communication channels in the wireless network access device cannot be balanced, and paired terminals of communication channels that cannot be balanced are identified. Namely, a terminal M corresponding to a task consuming 1 second and a terminal N corresponding to a task consuming 10 seconds are identified, which are carried by a communication channel 3, the terminal M and the terminal N are both residual terminals, and if the terminal M and the terminal N are unnecessary, a terminal with less time consumption required by the task is generally selected to perform balancing among cross-wireless network access devices, namely, the terminal M is selected.
S840: and respectively acquiring the time consumption of the remaining terminals for transmitting data through other wireless network access devices.
Respectively trying to transmit data through other wireless network access devices by the terminal M corresponding to the 1 second time-consuming task required for carrying the communication channel # 3, where there may be a case where the terminal M cannot transmit data through one or some wireless network terminal devices in other wireless network access devices, and in this case, the time required for recording is infinite.
S860: and balancing the terminals which are paired in the communication channels in the cross-wireless network access equipment according to the time consumption of the remaining terminals for transmitting data through other wireless network access equipment and the maximum time consumption required by tasks corresponding to the terminals paired in the communication channels in each wireless network access equipment.
And balancing the terminals which are paired with the communication channels in the cross-wireless network access equipment by adopting a repeated calculation mode for multiple times according to the principle of reducing the maximum time consumption required by the tasks corresponding to the terminals which are paired with the communication channels in each wireless network access equipment when the rest terminals are respectively paired with other wireless network access equipment.
In order to further explain the technical solution of the method and system for controlling optimization of a multi-terminal access wireless network in detail, a specific application example will be used for the following description.
The specific application examples are: 12 terminals T1-T12 with double communication mechanism, 3 Wi-Fi base stations B1, B2 and B3. Each Wi-Fi base station is connected with 3 terminals at most (each base station has 3 communication channels, and the record is M-3). The connection strength is S {0, 1, 2, 3, 4}5 gear. It is now necessary to transmit Y-12 megabytes of data to all terminals over Wi-Fi.
The method comprises the following steps: a signal strength matrix S (m, n) is obtained.
Through a self-owned communication mechanism, the signal connection strengths of all terminals and different Wi-Fi base stations are obtained, and a signal strength matrix S (m, n) is constructed, which is specifically shown in the following table 1.
TABLE 1 Signal Strength matrix S (m, n)
Step two: and converting the S (m, n) matrix into a communication time consumption matrix C (m, n).
According to the specific data communication task requirement, the time (unit is second) consumed by different terminals for transmitting data through different base stations is calculated, which is specifically shown in table 2 below.
| C(m,n) | T1 | T2 | T3 | T4 | T5 | T6 | T7 | T8 | T9 | T10 | T11 | T12 |
| B1 | X | 1 | 1 | 12 | 6 | 1 | 2 | 6 | 2 | X | 6 | 12 |
| B2 | X | 1 | 2 | 2 | 6 | 1 | 1 | 1 | X | X | 2 | 12 |
| B3 | 6 | 12 | 6 | 6 | 6 | 1 | 1 | 1 | X | 6 | 1 | 6 |
Note: in table 2, X represents a large number, and indicates that the terminal is communicating with the corresponding base station.
Step three: special terminals are prioritized.
In the C (m, n) matrix, only 1 corresponding terminals with a number different from X in each column are arranged to a corresponding base station (i.e., terminals that can only connect with a certain base station). As shown in Table 3 below, T1 was arranged in the B3-1 channel, T9 was arranged in the B1-1 channel, and T10 was arranged in the B3-2 channel. Arranged terminals, corresponding columns in the C (m, n) matrix are identified as arranged; the scheduled base station channel is also identified as scheduled. The number of the lattice occupied by Ti represents the time length (unit is second) consumed by the communication task, and each base station is connected with 3 terminals at most, which means that each base station can open 3 communication channels at a time, and the communication channels are counted as Bi-1, Bi-2 and Bi-3.
Table 3 communication channel pairing table in special terminal and base station
Step four: the normal terminal first round arrangement.
The terminal which is not arranged in the C (m, n) matrix selects the minimum number in the column (meaning the communication time with a certain base station is shortest) from the column vector of the C (m, n) matrix corresponding to the terminal, and arranges the terminal to the corresponding base station channel until all the base station channels are identified as arranged or all the terminals are identified as arranged. The results are shown in table 4 below.
Table 4 shows a first round of pairing table for communication channels between the common terminal and the base station
Step five: the normal terminal second round arrangement.
The terminals which are not scheduled (T4, T5 and T12 in the example) are selected from the corresponding C (m, n) matrix column, the minimum number in the column (meaning the shortest communication time with the base station) is selected, and the terminals are sequentially scheduled to the channel with the shortest communication task time in the corresponding base station. Until all terminals are scheduled or all base station channels are scheduled for a second round of communication tasks. The results are shown in Table 5 below.
Table 5 is a second round of pairing table of communication channels between the common terminal and the base station
Step six: and communication tasks in the same base station are balanced.
Aiming at the channel which occupies the longest time and has more than one communication task in the base station channel (such as B1-2, the communication task time of the channel is 7 seconds, and there are 2 communication tasks T2 and T5). And searching whether a channel with less communication tasks (such as B1-3, the communication task duration of the channel is 1 second) with the base station can receive a certain communication task in the original channel, so that the overall communication duration of the base station is reduced. In the example, the T2 task for the B1-2 channel was tuned to the B1-3 channel. After all the channels are searched, the adjusted strategy is output, and the result is shown in table 6 below.
Table 6 is a table for communication channel matching between the terminal and the base station after the communication task in the same base station is balanced
Step seven: and balancing communication tasks in the cross base station.
If the channel is searched, the communication tasks of the channel needing task balancing cannot be balanced in the base station (in the example, the B3-3 channel takes 7 seconds to carry out two communication tasks of T11 and T12, balancing adjustment is needed, but balancing cannot be finished in the base station). A search is made whether the communication tasks undertaken by the channel can be tuned to the appropriate channel of the other base station. (in the calculation example, after searching, the T11 task undertaken by the B3-3 channel can be adjusted to the B2-2 channel, as shown in Table 7 below). When the communication task is adjusted across the base stations, the adjusted communication task time may be different due to different signal connection strengths of the terminal and each base station. For example, in the example, T11 is borne by the B3 base station, which takes 1 second, and after being borne by the B2 base station, it takes 2 seconds.
Table 7 is a table for communication channel matching between the terminal and the base station after the communication task in the cross-base station is balanced
Step eight: if all the terminals are arranged, the scheme can be used as the optimization control output of the multi-terminal access wireless network. If there are not scheduled terminals. And repeating the fifth step, the sixth step and the seventh step until all the terminals are arranged and outputting.
As shown in fig. 3, a system for controlling optimization of a multi-terminal access wireless network includes:
a time consumption obtaining module 200, configured to obtain time consumption required for each terminal to transmit data through each wireless network access device.
The first pairing module 400 is configured to pair each terminal with a communication channel in each wireless network access device according to a minimum time consumption rule and a rule that only a single communication channel in a single wireless network access device allows access to a single terminal.
The second pairing module 600 is configured to, when an unpaired terminal exists, select a wireless network access device according to a minimum time consuming principle required for data transmission between the unpaired terminal and the wireless network access device, and pair the unpaired terminal with a communication channel in the wireless network access device according to the minimum time consuming principle required for a loaded task in the communication channel in the wireless network access device.
The invention relates to a multi-terminal access wireless network optimization control system, which acquires the time consumption required by each terminal for transmitting data through each wireless network access device, pairs each terminal with the communication channel in each wireless network access device according to the minimum time consumption principle required and the principle that a single communication channel in a single wireless network access device only allows to access a single terminal, selects the wireless network access device according to the minimum time consumption principle required by the data transmission between the unpaired terminal and the wireless network access device when the unpaired terminal exists, and pairs the unpaired terminal with the communication channel in the wireless network access device according to the minimum time consumption principle required by the loaded task in the communication channel in the wireless network access device. In the whole process, based on the principle that the time required for the terminal to transmit data through the wireless network access equipment is the minimum, the terminal and the wireless network access equipment are reasonably paired, the overall time consumption of communication between a plurality of terminals and a plurality of wireless network optimization equipment is finally effectively reduced, the wireless network blockage caused by the fact that a plurality of terminals access the wireless network is avoided, and the data transmission efficiency of the terminal through the wireless network is improved.
