Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a wireless communication optimization method, apparatus, storage medium, and computer device.
Background
In application occasions such as large conferences and classroom teaching, a paperless conference/teaching system based on communication is widely applied. Taking a large representative conference as an example, in the conference process, the main control computer needs to download a specific proposal material to a voter terminal used by each representative through a communication base station, and after the representative votes the proposal by the voter in a name-recording or anonymous-voting manner, the voted data is fed back and transmitted to the base station for further processing. Obviously, in the above application, in order to ensure the real-time performance of the conference, the main control computer needs to transmit the same data amount of data to all terminals in the shortest possible time through the wireless base station.
Assuming that data needs to be transmitted to M terminals, each terminal has a unique number, which may be assumed to be D1-DM. The general communication method is as follows: the base station transmits the data blocks to all terminals in a broadcast manner, since there may be communication errors. After the transmission is completed, the base station needs to call in turn to inquire whether the D1-DM terminals receive the data block, and the terminal feeds back a message of successful/unsuccessful data reception. If the terminal does not successfully receive the data, the base station performs the operations of data transmission, roll call inquiry and feedback until all the terminals successfully receive the data. It is assumed that the probability (error rate) of successful data reception of the terminal during data transmission is 1-P. The transmission time of the data block is T1, the transmission time of the roll call inquiry command is T2, and the terminal feedback time is T3. Under the above conditions, the average time for the base station to transmit the data block to all M terminals may be expressed by the following test:
the Max value is a value which can successfully transmit data by repeating data transmission at most for a certain terminal, and a specific value of the Max value is related to the bit error rate P. Obviously, the communication method needs a long time, and communication optimization is urgently needed to shorten the communication time.

Detailed Description
As shown in fig. 1, a method for optimizing wireless communication includes the steps of:
s100: and acquiring a preset terminal grouping scheme, and identifying the terminals included in each terminal group, wherein the preset terminal grouping scheme satisfies that at least one terminal group includes at least two terminals.
The preset terminal grouping scheme is a preset scheme, and can be set according to the needs of actual situations, specifically, it needs to meet the requirement that at least one terminal group includes at least two terminals, that is, at least one terminal in each terminal group includes two or more terminals. Optionally, the terminal grouping scheme may be preset to divide all terminals into a plurality of terminal groups, i.e. the number of terminals in each terminal group is the same. For example, there are currently 9 terminals, which may be divided into 3 terminal groups on average, or may be divided into 4 terminal groups including 1 terminal, 2 terminals, 4 terminals, and 2 terminals. It should be noted that, in the process of terminal grouping average assignment, if a decimal point occurs on average, the number of terminals in each terminal grouping is assigned by dividing the number of terminals in each terminal grouping, and then the remainder of the division is used as a terminal grouping alone. The preset terminal grouping scheme can be generated by the server side, or can be directly imported to the server side from the outside. Here, the terminal grouping scheme set in advance is directly read, and the terminals included in each terminal group are identified.
S200: and sending the required transmission data to each terminal.
The server sends data required to be transmitted to each terminal, for example, the server sends data of a certain scheme to each user terminal, so that a user can browse the scheme.
S300: and when the transmission of the data required to be transmitted is finished, respectively sending a data receiving condition inquiry message to the terminal group which sends the data required to be transmitted in the current round.
When the transmission of the transmission-required data is completed in step S200, the server sends a data reception condition query message to each terminal group, and queries, in units of terminal groups, the condition that the terminal receives data in each terminal group.
S400: and receiving the data receiving condition information returned by each terminal group, and identifying the terminal group which does not successfully receive the data required to be transmitted according to the data receiving condition information.
The server receives data receiving condition messages returned by each terminal, and the data receiving condition messages carry terminal group identification marks (used for distinguishing different terminal groups), terminal identification marks (used for distinguishing different terminals) and terminal data receiving conditions, wherein the terminal data receiving conditions comprise two types of successful receiving of required transmission data and unsuccessful receiving of required transmission data. Based on the data receiving condition message, the server can identify all terminals which have successfully received the data required to be transmitted and all terminals which have not successfully received the data required to be transmitted, and further identify the terminal groups which have successfully received the data required to be transmitted and the terminal groups which have not successfully received the data required to be transmitted. For example, a conference room has 32 terminals in total of 1 to 32, and on average, each 8 terminals are divided into a terminal group, that is, the terminal group 1 includes (1 to 8 terminals), the terminal group 2 includes (9 to 16 terminals), the terminal group 3 includes (17 to 24 terminals), and the terminal group 4 includes (25 to 32 terminals), if the terminal 11, the terminal 14, and the terminal 18 are identified as not successfully receiving the transmission data, the terminal group which is not successfully receiving the transmission data is identified as the terminal group 2 and the terminal group 3, and the terminal group which is successfully receiving the transmission data is identified as the terminal group 1 and the terminal group 4.
S500: and sending the required transmission data to the terminal group which does not successfully receive the required transmission data again, and returning to the step of sending a data receiving condition inquiry message to the terminal group which sends the required transmission data in the current round respectively when the required transmission data is transmitted, until each terminal successfully receives the required transmission data.
And for the terminal group which does not successfully receive the required transmission data, retransmitting the required transmission data, returning to the step S300, and circularly executing the steps until each terminal successfully receives the required transmission data. Continuing taking the conference room as an example, when the terminal group 2 and the terminal group 3 are identified as the terminal groups which do not successfully receive the required transmission data in step S400, the required transmission data is sent to the terminal group 2 and the terminal group 3 again, returning to step S300, when the required transmission data is sent completely, sending a data receiving condition inquiry message to the terminal group 2 and the terminal group 3 to inquire the receiving conditions of the terminal group 2 and the terminal group 3, if only the remaining terminal 18 is identified as not successfully receiving the required transmission data, sending the required transmission data to the terminal group 3 again, and sequentially circulating the above operations until the terminals 1 to 32 successfully receive the required transmission data.
The wireless communication optimization method comprises the steps of obtaining a preset terminal grouping scheme, identifying terminals included in each terminal group, sending required transmission data to each terminal, respectively sending a data receiving condition inquiry message to the terminal group sending the required transmission data in the current round when the required transmission data is transmitted, receiving the data receiving condition message returned by each terminal group, identifying the terminal group which does not successfully receive the required transmission data according to the data receiving condition message, and resending the required transmission data until each terminal successfully receives the required transmission data. In the whole process, only one data receiving condition inquiring operation needs to be carried out on the terminals in a single terminal group in one cycle, and in the subsequent cycle, the data receiving condition inquiring operation is not carried out on all the terminals in the terminal group which have successfully received the required transmission data terminals, so that the time consumed by wireless communication can be reduced by the whole scheme.
As shown in fig. 2, in one embodiment, step S100 further includes:
s120: identifying a current online terminal;
s140: and dividing the current online terminal into M terminal groups to generate a preset terminal group scheme, wherein M is a positive integer.
Generally speaking, in order to avoid wasting meaningless data transmission resources and time, we only need to send data to be transmitted to online terminals, and therefore, here, the current online terminal is identified first, the current online terminal is divided into M terminal groups, and a preset terminal group scheme is generated, where the preset terminal group also needs to meet the requirement that at least one terminal group includes at least 2 terminals. In particular, all terminals may be equally allocated as M terminal groups. Furthermore, since one byte has 8 bits, every 8 terminals can be divided into one terminal group, which facilitates transmission of a data reception status message.
As shown in fig. 2, in one embodiment, step S400 includes:
s420: receiving data receiving condition information returned by each terminal group;
s440: updating the feedback state of each terminal according to the data receiving condition message, wherein the feedback state of the terminal is not required to be fed back again when the terminal successfully receives the required transmission data, and the feedback state of the terminal is required to be fed back again when the terminal does not successfully receive the required transmission data;
s460: and identifying the feedback state of the terminal in each terminal group as the terminal group needing to be fed back again.
And receiving a data receiving condition message returned by each terminal group, updating the feedback state of the terminal according to the received message, feeding back the terminal without feedback again if the terminal has successfully received the required transmission data, and indicating that the terminal needs to feed back again if the terminal has not successfully received the required transmission data, namely, the terminal needs to resend the required transmission data. Continuing with the above conference room as an example, assume that the terminal has a flag of 0 when it does not need to feed back again and a flag of 1 when it needs to feed back again. Initially, the feedback states of the terminals grouped by 4 terminals are 11111111, and after the data required for the first transmission is sent, if the terminals No. 11, No. 14, and No. 18 are identified as not successfully receiving the required transmission data, the feedback states of the updated terminals are 00000000, 00100100100, 01000000, and 00000000, and the terminal No. 3 group to which the terminal No. 11 and the terminal No. 14 belong and the terminal No. 4 group to which the terminal No. 18 belongs are identified, and the required transmission data is retransmitted.
In one embodiment, the step of identifying that the feedback state of the terminal in each terminal group is the terminal group which needs to be fed back again further includes:
the method comprises the following steps: identifying the feedback state as a terminal needing to be fed back again, and marking the terminal as a terminal needing to be fed back again;
step two: recognizing the sequence of the terminal fed back again in the corresponding terminal group;
step three: and receiving the message returned by the terminal for feeding back again according to the sequence.
In this embodiment, it is necessary to identify a terminal whose feedback state is to be fed back again in the same terminal group, and continuing to take the conference room as an example, there are terminal No. 11 and terminal No. 14 in terminal No. 3 group as terminals that are to be fed back again, and terminal No. 11 is sequentially in front of terminal No. 14 in terminal No. 3 group, and according to this sequence, a message returned by terminal No. 11 is received first, and then a message returned by terminal No. 14 is received, so that mutual influence between data can be avoided. More specifically, terminal No. 11 may return a message to the server in the first communication cycle, and terminal No. 14 may return a message to the server in the next communication cycle.
In one embodiment, the step of updating the feedback status of each terminal includes:
and representing and updating the feedback state of each terminal by adopting binary number.
The binary number comprises 0 and 1, the feedback state of the terminal can be represented by 1 as needing to be fed back again, and the corresponding feedback state of the terminal represented by 0 is not needed to be fed back again; and also, the feedback state of the terminal represented by 0 is required to be fed back again, and the corresponding feedback state of the terminal represented by 1 is not required to be fed back again.
In one example, the data receiving condition query message includes a query instruction, a data transmission request identification, a terminal grouping identification and a terminal feedback state query word.
The query instruction is used for indicating the terminal to query the data receiving condition, the identification mark of the data to be transmitted is used for distinguishing the current data to be transmitted, the identification mark of the terminal group is used for distinguishing different terminal groups, and the query word of the terminal feedback state is used for indicating the terminal to feed back the corresponding feedback state, such as feedback 0 or 1.
As shown in fig. 3, a wireless communication optimization apparatus includes:
the grouping module 100 is configured to obtain a preset terminal grouping scheme, and identify a terminal included in each terminal group, where the preset terminal grouping scheme satisfies that at least one terminal group includes at least two terminals.
And the data issuing module 200 is configured to send required transmission data to each terminal.

The identifying module 400 is configured to receive a data receiving condition message returned by each terminal packet, and identify a terminal packet that does not successfully receive the data required to be transmitted according to the data receiving condition message.
The loop module 500 is configured to send the required transmission data to the terminal group that did not successfully receive the required transmission data, and control the receiving inquiry module and the identification module to re-execute the corresponding operation until each terminal successfully receives the required transmission data.
The invention discloses a wireless communication optimizing device.A grouping module 100 acquires a preset terminal grouping scheme, identifies terminals included in each terminal group, a data issuing module 200 sends required transmission data to each terminal, when the required transmission data is completely transmitted, a receiving inquiry module 300 respectively sends data receiving condition inquiry messages to the terminal groups which send the required transmission data in the current round, an identification module 40 receives the data receiving condition messages returned by each terminal group, identifies the terminal groups which do not successfully receive the required transmission data according to the data receiving condition messages, and a circulation module 500 resends the required transmission data until each terminal successfully receives the required transmission data. In the whole process, only one data receiving condition inquiring operation needs to be carried out on the terminals in a single terminal group in one cycle, and in the subsequent cycle, the data receiving condition inquiring operation is not carried out on all the terminals in the terminal group which have successfully received the required transmission data terminals, so that the time consumed by wireless communication can be reduced by the whole scheme.

the identifying unit 460 is configured to identify that the feedback state of the terminal in each terminal group is a terminal group that needs to be fed back again.
In one embodiment, the identifying module 400 is further configured to identify a terminal whose feedback status is to be fed back again, and mark the terminal as a terminal to be fed back again; recognizing the sequence of the terminal fed back again in the corresponding terminal group; and receiving the message returned by the terminal for feeding back again according to the sequence.
In order to further explain the technical solution of the wireless communication optimization method and apparatus of the present invention and the effect thereof in detail, a specific example will be used for explanation.
1. N terminals are grouped, each group being an integer multiple of 8 (i.e., 8 or 16, 24, 32, etc., since 1 byte is 8 bits.) and the following discussion is presented in terms of 8 per group. For example, there are 1024 terminals, divided into 128 groups of 8 (or 16).
2. And the main control computer calls the names of all the terminals through the base station and receives feedback to confirm that all the terminals are on line. And finishing grouping pairing according to the grouping rule.
3. The main control computer broadcasts the data block to be transmitted to all the terminals through the base station. The basic structure of a data block is: data head, data section, data tail.
4. After the data transmission is finished, the main control computer queries the terminal data receiving condition through the base station grouping. The inquiry command includes the following: inquiry command (one byte), packet number (two bytes), inquiry group number (one byte) inquiry terminal status word (one byte). Wherein, the query group number is a 16-system number from 0 to 127 and represents the group number. The "inquiry terminal status word" is a binary number, and each bit of the binary number represents whether a certain terminal in the group needs to feed back the status. For example: "11111111" represents that all 8 terminals in the group need to feed back the reception status. "01000100" represents that the 2 nd and 6 th terminals need feedback status. It is apparent that initially, the query status word for each group is "11111111".
5. After receiving the inquiry command, the terminal feeds back the state according to the following rules. If the bit corresponding to the 'inquiry terminal state word' of the terminal is '1', the data receiving state needs to be fed back and submitted. The '1' corresponding to the terminal is the Mth '1' in the 'inquiry terminal state word', and then the Mth communication cycle after receiving the instruction submits the data receiving state information to the base station. For example: the "query terminal status word" is "11111111", and all the terminals in the group need to sequentially feed back the status of submitting data reception. If the 'inquiry terminal state word' is '01000100', the 2 nd terminal in the group submits state feedback in the 1 st period after receiving the instruction; the 6 th terminal in the group submits state feedback in the 2 nd cycle after receiving the instruction.
6. And after receiving the terminal state feedback, the base station carries out corresponding operation on the 'inquiry terminal state word'. The rules are as follows: when a data task starts, each group of terminals has a status word, the initial value is '11111111', which represents that all the terminals in the group need to perform data transmission and perform receiving status query. If the base station receives the data receiving confirmation information of a certain group of terminals, the corresponding position is 0. For example, the 1 st, 3 rd, 4 th, 5 th, 7 th, 8 th in the group, which has already been received, sets the status word to "01000100".
7. The above process is cycled through until all terminals have received the data (all status words are "00000000") performance analysis:
compared with the prior art, the communication time can be effectively shortened.
Furthermore, the present invention also provides a computer-readable storage medium, which stores a computer program that, when executed by a processor, performs the steps of the method as described above. For the same reason, only one data reception condition query operation needs to be performed on the terminals in a single terminal group in one cycle, and in a subsequent cycle, the data reception condition query operation is not performed on all the terminals in the terminal group which have successfully received the data transmission request terminal, so that the time consumption of wireless communication can be reduced in the whole scheme.
In addition, the present invention also provides a computer device, which includes a memory, a processor and a computer program stored in the memory and capable of running on the processor, wherein the processor implements the steps of the method when executing the program. For the same reason, only one data reception condition query operation needs to be performed on the terminals in a single terminal group in one cycle, and in a subsequent cycle, the data reception condition query operation is not performed on all the terminals in the terminal group which have successfully received the data transmission request terminal, so that the time consumption of wireless communication can be reduced in the whole scheme.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
