Illustratively, the unified data block has 1 added to its retransmission times per retransmission. And when judging that the retransmission times of a certain data block is greater than a first preset time (such as 2 times), performing process creation to retransmit the data.
Further, whether the retransmission times is greater than a second preset time (for example, 4 times) is judged, and if so, a new transmission process is created for sending normal data. In one embodiment, the newly created transmission process has the same property as the original transmission process, and is a process for sending original data content, and more processes capable of sending original data are added through the creation of the new process to perform parallel data sending.

Fig. 5 is a flowchart of another method for changing data transmission content according to feedback latency according to an embodiment of the present invention, and a specific caching mechanism is provided. As shown in fig. 5, the technical solution is as follows:
step S501, determining the data application type of the currently sent data block, wherein the data application type corresponds to different application functions in the same application program of the corresponding terminal equipment.
In one embodiment, for the same application program, different application functions correspond to different data types, which are divided in the present scheme, and corresponding data transmission mechanisms are allocated based on the divided data types. Illustratively, the base station sends the data block to the terminal device, so that the terminal device executes a corresponding function according to the content of the data block after receiving the data block, and illustratively, the terminal device app1 corresponds to the function module 1, the function module 2, and the function module 3, where the function module 1 is an update of a user data information form, the function module 2 is a corresponding update of an interface value, and the function module 3 is a corresponding display animation display. In this step, the data application type of the sent data block is determined, specifically, the data application type may be determined according to the specific data content of the data block, for example, the update content of the information form is data type 1, the interface numerical value update data is data type 2, and the animation display data is application type 3. The specific identification process may also be that when the terminal device interacts with the base station, corresponding data type information, such as data type 1, data type 2, or data type 3, is appended when sending the data block of the same function module, and when the base station performs a data response, the data type of the data block that needs to be responded currently is determined according to the data type of the previously received data record.
Step S502, determining corresponding identification information according to the data application type, and adding the identification information to the data block.
In one embodiment, after the data type of the data block is determined, the corresponding data transmission identifier is determined according to the data application type. Illustratively, data type 1 corresponds to identification information 1, and data type 2 corresponds to identification information 2. Specifically, the data transmission identifier is added to the data block, the Sub Type content of the field is assigned when the data block is generated, the assignment of the identifier information 1 is 0100, and the assignment of the identifier information 2 is 0101.
Step S503, in the data transmission process, determining frame number information of a data block to be transmitted, determining a corresponding data check type according to the frame number information, and allocating a transmission process with the same data check type to the data block to be transmitted.
Step S504, in the data transmission process, when a retransmission data instruction corresponding to a certain transmission process is detected, the retransmission times of the retransmission instruction associated data are determined, and if the retransmission times are larger than a first preset time, a new transmission process is created for retransmitting the associated data.
And step S505, monitoring each transmission process configured by the retransmission mechanism, and determining the feedback waiting time of each transmission process.
Step S506, when the transmission progress which is created currently is detected to reach the upper limit, caching the data block to be transmitted, and meanwhile, periodically adjusting the position of the data block to be transmitted in the cache queue.
Illustratively, the upper limit value may be 10. In one embodiment, if the number of current transmission processes has reached the upper limit, the data to be transmitted is buffered, such as added to a queue of data to be transmitted. In the scheme, when the number of processes in the system is limited, whether the upper limit of the transmission process is reached is judged, if not, a new transmission process is correspondingly created, namely, each newly created transmission process can be specially used for sending a single data block.
In one embodiment, the process of cycle queue adjustment is further included when buffering the data block. Specifically, if the queue length is greater than 40, the queue position is adjusted according to data block information corresponding to the data block in the buffer queue, where the data block information includes an original sending process for sending the data block. Illustratively, the data blocks in the data block information for the same sending process are adjusted to adjacent positions.
Step S507, when it is detected that the feedback waiting time in a certain transmission process is greater than the data block sending processing time, the data block to be transmitted is retrieved from the buffer queue, and grouping of the data block is performed according to the identification information of the data block to be transmitted.
And step S508, sending the grouped data blocks in sequence according to the grouping condition, wherein the sending time interval of each group of data blocks is greater than the set time slot duration.
According to the scheme, the data application type of the currently sent data block is determined, the data application type corresponds to different application functions in the same application program of the corresponding terminal equipment, the corresponding identification information is determined according to the data application type, the identification information is added into the data block, the subsequent data block grouping is facilitated, the identification information determining mode is determined according to the data application type, and the grouping mode is better in basis. Meanwhile, when the transmission process established currently reaches the upper limit, the data blocks to be transmitted are cached, and the position of the data blocks to be transmitted in the cache queue is adjusted periodically, so that the distribution efficiency is improved, the process of independently judging and distributing each data block is avoided, and the data transmission efficiency is improved.
Fig. 6 is a flowchart of another method for changing data transmission content according to feedback waiting time according to an embodiment of the present invention, which provides a specific method for sequentially transmitting grouped data blocks according to grouping situations. As shown in fig. 6, the technical solution is as follows:
step S601, determining a data application type of the currently sent data block, wherein the data application type corresponds to different application functions in the same application program of the corresponding terminal equipment.

Step S603, in the data transmission process, determining frame number information of a data block to be transmitted, determining a corresponding data check type according to the frame number information, and distributing a transmission process with the same data check type for the data block to be transmitted.
Step S604, in the data transmission process, when a retransmission data instruction corresponding to a certain transmission process is detected, determining the retransmission times of the retransmission instruction associated data, and if the retransmission times is greater than a first preset time, creating a new transmission process for retransmitting the associated data.
Step S605, monitoring each transmission process configured by the retransmission mechanism, and determining the feedback waiting time of each transmission process.
Step S606, when the transmission progress which is created currently is detected to reach the upper limit, caching the data block to be transmitted, and meanwhile, periodically adjusting the position of the data block to be transmitted in the cache queue.
Step S607, when it is detected that the feedback waiting time in a certain transmission process is greater than the data block sending processing time, the data block to be transmitted is retrieved from the buffer queue, and the data block is grouped according to the identification information of the data block to be transmitted.
Step S608, determining the association degree of each grouped data block, and sorting according to the association degree; and sequentially transmitting each group of data blocks according to the sequencing result.
In one embodiment, the data blocks are grouped according to different data information types, and the association degree of each grouped data block can be further determined after grouping is finished. Specifically, the association degree of the data blocks for the same application is set as association, and the data blocks for different applications are set as non-association. Illustratively, there are a total of 10 data block packets, packet 1, packet 2, packet 3, packet 4, packet 5, packet 6, packet 7, packet 8, packet 9, and packet 10, respectively. The respective corresponding applications are as follows:
| group 1 | Group 2 | Group 3 | Group 4 | Group 5 | Group 6 | Group 7 | Packet 8 | Packet 9 | Packet 10 |
| Procedure a | Procedure b | Procedure c | Procedure b | Procedure c | Procedure a | Procedure a | Procedure b | Procedure b | Procedure c |
After sorting by relevance, the grouping is as follows:
| group 1 | Group 6 | Group 7 | Group 4 | Group 2 | Packet 8 | Packet 9 | Group 3 | Group 5 | Packet 10 |
| Procedure a | Procedure a | Procedure a | Procedure b | Procedure b | Procedure b | Procedure c | Procedure c | Procedure c | Procedure c |
In performing the data block transmission, the transmission is performed in the order of packet 1, packet 6, packet 7, packet 4, packet 2, packet 8, packet 9, packet 3, packet 5, and packet 10.
According to the scheme, the relevance of each grouped data block is determined, and sequencing is carried out according to the relevance; and sequentially transmitting each group of data blocks according to the sequencing result, so that the transmission process continuously or parallelly processes the associated data blocks, and a data transmission mechanism is further optimized.
On the basis of the technical scheme, the feedback waiting time is adaptively adjusted according to the complexity of the link, and the adjusting step comprises the following steps: initializing quality change parameters of a communication channel, sending an individual data frame to a plurality of terminal devices through a current transmission process, and keeping the individual data frame in a waiting state, and sending a next data frame according to feedback information of the plurality of terminal devices after receiving the feedback information; receiving a first communication signal sent by first equipment, determining a first communication quality parameter, receiving a second communication signal sent by second equipment after a preset time interval, and determining a second communication quality parameter, wherein the first equipment and the second equipment are different terminal equipment with the same application type; and correcting the quality change parameter according to the first communication quality parameter and the second communication quality parameter, and determining the feedback waiting time according to the quality change parameter.
In one embodiment, after the first communication quality parameter and the second communication quality parameter are determined, the quality variation parameter is corrected according to the first communication quality parameter and the second communication quality parameter. Specifically, the method comprises the following steps: and multiplying the ratio of the second communication quality parameter to the first communication quality parameter by the quality change parameter obtained after initialization, and updating the quality change parameter according to the obtained result. By correcting the quality variation parameter, the transmission mode is not changed based on the actual condition of a single channel, but data is updated based on the variation trend of the channel. And after the quality change parameter is corrected, correspondingly determining the feedback waiting time based on the corrected quality change parameter. For example, when the quality variation parameter is 35, the feedback waiting time may be 8 s; when the mass variation parameter is 30, the first preset number may be 10 s.
According to the scheme, the value of the feedback waiting time is adaptively adjusted according to the quality change parameter, so that the method for changing the data transmission content according to the feedback waiting time can adaptively adjust the feedback waiting time according to the link condition, and the change and adjustment of the transmission content can be accurately and flexibly carried out subsequently.
