[0029] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are merely illustrative of the embodiments of the invention, and are not limited to the embodiments of the present invention. It will also be also necessary to explain that only the parts related to the embodiment of the present invention are shown in the drawings rather than all structures.

[0030] figure 1 A flowchart of a method of transmitting content changes in accordance with the feedback latency of the present invention, the present embodiment can be applied to the transmission process of data, and specifically includes the following steps:

[0031] Step S101, during the data transmission process, monitor the various transmission processes configured by the retransmission mechanism to determine the retransmission latency of each of the transmission processes.

[0032] During data transmission, the transmitting end transmits data to the receiving end, the receiving end performs data check to determine the accuracy and integrity of the data, if the data is erroneous or missing, then the retransmission instruction is transmitted to the data transmission end, and the transmitting end is received. Re-transmit the corresponding associated data block after the retransmission instruction until the receiving end correctly receives the data position, thereby ensuring the accuracy of the data link transmission data.

[0033] Typically, instructions waiting to be returned after sending data after sending data to determine whether to retransmit data or send new data, in order to improve data transmission throughput, create a process of configuring multiple data transmission. In one embodiment, the different transmission processes set the retransmission latency of the corresponding transmission data, and during the data transmission process, each transmission process configured by the retransmission mechanism is monitored to determine the weight of each of the transmission processes. The wait time.

[0034] Step S102 When the retransmission latency in a transmission process is detected is greater than the data block transmission time, the new data block is added to the transmission process, and the packet of the data block is performed.

[0035] In one embodiment, if there is eight processes, it is a process 1, process 2, process 3, process 4, process 5, process 6, process 7, and process 8, respectively. Each process respectively corresponds to a retransmission latency, such as detected the retransmission wait time of the process 4 is N (exemplary N is 3 seconds), which is greater than the transmission processing time S (exemplary S is 2 seconds). ), Add new data blocks to the transfer process and packets for data blocks.

[0036] In one embodiment, the packet mode can be divided according to the data parameter type of the data block itself. Exemplary, frame format of each data block is as follows:

[0037] Frame header IP address TCP header data Frame end CRC Group identification

[0038] The data parameter type of the data block can be recorded in the packet identification field. In this embodiment, the data blocks of the data parameter type are divided into the same group.

[0039] In step S103, the packet is transmitted in accordance with the packet case, and the transmission time interval of each group data block is greater than the set time slot.

[0040] Figure 1A A process diagram of a data block packet and transmission is provided for an embodiment of the present invention. Exemplary, the number of data blocks to be transmitted to the current process 4 is 7, and the packet identifier corresponding to each data block is Figure 1A As shown, the order in which the packet after the packet is data 1, data 3, data 2, data 6, data 7, data 4, and data 5. The data after the packet is completed is transmitted in sequence by process 4, wherein there is a certain time interval between group data blocks when transmitting, the time interval is greater than the set time slot. Exemplary, the set time slot can be the retransmission wait time value of the current process.

[0041] According to the above scheme, the present scheme is configured with a corresponding retransmission latency, and performs the configuration transmitted by the data block according to the different retransmission latency, and the transmission process uses a packet transmission method, which can be efficiently utilized. Waiting time gaps to improve data transmission efficiency.

[0042] figure 2 Another method of transmitting content changes based on the feedback latency of the present invention, which gives a specific method for transmitting process monitoring. Such as figure 2 As shown, the technical solution is as follows:

[0043] Step S201, during the data transmission process, monitor the transmission process created according to the data check type of the data to be transmitted; and / or monitor the transmission process created according to the number of data retransmission, determine each of the transmission The retransmission wait time of the process.

[0044] In one embodiment, the creation of the transmission process is further limited. Among them, in the data transmission process, monitor the transmission process created according to the data check type of the data to be transferred, and the transmission process created according to the number of data retransmissions. That is, the process is not previously created in advance or the system, but is created according to the data check type during the data transmission, and the number of retransmissions of the data is statistically, and the creation of the transmission process according to the specific conditions of the retransmission. And monitor the created transport process.

[0045] Step S202 When the retransmission latency in a transmission process is detected is greater than the data block transmission time, the new data block is added to the transmission process, and the packet of the data block is performed.

[0046]In step S203, the data block is transmitted in accordance with the packet sequentially, and the transmission time interval of each group data block is greater than the set time slot.

[0047] According to the above scheme, during the data transmission process, the transfer process created according to the data check type of the data to be transmitted is monitored; and / or the transmission process created according to the number of data retransmission is optimized to optimize the transmission process. The allocation and creation mechanism enables subsequent feedback-based wait time to perform data transmission content changes.

[0048] image 3 A flowchart of another method for transmitting content changes in accordance with the feedback latency of the present invention, which gives a specific method of a transmission process created according to a data check type according to the data block to be transmitted. Such as image 3 As shown, the technical solution is as follows:

[0049] Step S301, in the data transmission process, determine the frame number information of the data block to be transmitted, determine the corresponding data check type according to the frame number information, and assigns the transmission process of the same data verification type for the transmission data block. .

[0050] Among them, different transmission data uses different verification methods due to their own characteristics to ensure accurate transmission of data. Exemplary check methods include parity, CRC checks or sea code checks. By parsing the check field in the frame number information to obtain the corresponding data frame of the data frame. Among them, different transmission processes each corresponding to a data frame, assigning a first transmission process having the same data check type for the pending data block.

[0051] Step S302, monitor the various transmission processes configured by the retransmission mechanism to determine the retransmission latency of each of the transmission processes.

[0052] Step S303 When the retransmission latency in a transmission process is detected is greater than the data block transmission time, the new data block is added to the transmission process, and the packet of the data block is performed.

[0053] In step S304, the data block of the packet is transmitted in accordance with the packet case, and the transmission time interval of each group data block is greater than the set time slot.

[0054] According to the above scheme, in the present scheme, in the data transmission process, the frame number information to be transmitted to be transmitted is determined in the data transmission process, and the corresponding data check type is determined according to the frame number information, and the signal to be transmitted data block has the same data. The transfer process of the calibration type avoids multiple different processes for cross-processing for different data types, and improves data transmission efficiency.

[0055] Figure 4 Another method of transmitting content changes based on the feedback latency of the present invention gives a method of transmitting a transmission process based on data retransmission. Such as Figure 4 As shown, the technical solution is as follows:

[0056] In step S401, during the data transmission process, when a retransmission data instruction corresponding to a transmission process is detected, the number of retransmissions of the retransmission instruction correlation data is determined, and if the number of retransmission is greater than the first preset number, Then create a new transmission process for retransmission of the associated data.

[0057] In one embodiment, when the data received by the receiving end is incomplete, or when the data is missing, the retransmission command is transmitted to the transmitting end, the retransmission instruction records the data that needs to be retransmitted and the corresponding transmission process. When the retransmission data instruction corresponding to a transmission process is detected, the number of retransmission of the retransmission instruction correlation data is determined. Exemplary, a unified data block plus one retransmission number of retransmission 1. When it is judged that the number of retransmissions of a certain data block is greater than the first preset number (such as 2), the process is created to perform the retransmission of the data.

[0058] Further, it is judged whether or not the number of retransmission is greater than the second predetermined number of times (such as 4), if so, create a new transmission process for transmission of normal data. In one embodiment, the newly created transmission process is the same as the original transmission process, all of which transmits the original data content, through the creation of the new process, to add more processes that can send raw data, parallel Data transmission.

[0059] Step S402, monitor the various transmission processes configured by the retransmission mechanism to determine the retransmission wait time of each of the transmission processes.

[0060] Step S403 When the retransmission latency in a transmission process is detected is greater than the data block transmission time, the new data block is added to the transmission process, and the packet of the data block is performed.

[0061] Step S404, the data block is transmitted in accordance with the packet, and the transmission time interval of each group data block is greater than the set time slot.

[0062] According to the above scheme, during the data transmission process, when a retransmission data instruction corresponding to a transmission process is detected, the number of retransmissions of the retransmission instruction correlation data is determined, and if the number of retransmission is greater than the first preset The number of times is created, and the new transmission process is created for retransmission of the associated data, thereby avoiding the blocking problem that the same data block is repeatedly retransmitted to cause normal data transmission, if the number of retransmission Big than the second preset number, create a new transmission process for transmission of normal data, thereby increasing the number of transmission processes when the retransmission data is increased, to ensure data transmission efficiency.

[0063] Figure 5 Another method of transmitting content changes in accordance with the feedback latency of the present invention gives a specific cache mechanism. Such as Figure 5 As shown, the technical solution is as follows:

[0064] Step S501, determine the data application type of the currently transmitted data block, the data application type, corresponding to the type corresponding to the different application functions in the same application in the terminal device.

[0065] In one embodiment, for the same application, different application functions correspond to different data types, which are divided in this scenario, and based on this assigned data transmission mechanism. Exemplary, the base station is transmitted to the terminal device so that the terminal device performs the corresponding function, exemplary, terminal device App1 corresponding function module 1, function module 2, function according to data block content, exemplary, terminal device APP1 corresponding function module 1, function module 2, function according to data block content Module 3, wherein the function module 1 is an update of the user data information form, the functional module 2 is a corresponding interface numerical update, and the function module 3 is a corresponding display animation display. This step is determined to determine the data application type of the transmitted data block, specifically, the data application type can be determined according to the specific data content of the data block, such as the update content of the information form is data type 1, the interface value update data is data type 2, Animation show data is the application type 3. The specific identification process may also be a terminal device interacting with the base station, and the corresponding data type information is attached when transmitting the data block of the same function module, such as data type 1, data type 2 or data type 3, when the base station is performing data In response, the data type of the data block that needs to be responded is determined based on the data type previously received data record.

[0066] In step S502, the corresponding identification information is determined according to the data application type, and the identification information is added to the data block.

[0067] In one embodiment, after determining the data type of the data block, the corresponding data transmission ID is determined according to the data application type. Exemplary, data type 1 correspondence information 1, data type 2 corresponds to identification information 2. Specifically, the data transmission ID is added to the data block, and the field Sub Type content is assigned, and the identification information 1 is assigned 0100, and the identification information 2 is assigned 0101.

[0068] In step S503, during the data transmission process, determine the frame number information of the data block to be transmitted, determine the corresponding data check type according to the frame number information, and assign the transmission process of the same data check type for the transmission data block. .

[0069] In step S504, during the data transmission process, when a retransmission data instruction corresponding to a transmission process is detected, the number of retransmissions of the retransmission instruction is determined, and if the number of retransmission is greater than the first predetermined number of times, Then create a new transmission process for retransmission of the associated data.

[0070] Step S505, monitor the respective transmission processes configured by the retransmission mechanism to determine the retransmission latency of each of the transmission processes.

[0071] Step S506, when detecting that the currently created transmission process reaches the upper limit, the transmission data block is cached, and the transmission data block in the cache queue is regularly adjusted periodically.

[0072] Exemplary, the upper limit value can be 10. In one embodiment, if the current transmission process has reached the upper limit, the data to be transmitted is cached, such as adding to the data queue to be transferred. In this scenario, when there is a limit on the number of processes in the system, it is determined whether or not the upper limit of the transmission process is reached. If not, the corresponding creation of a new transmission process, that is, each newly built transmission process can be specifically used for a single data block. send.

[0073] In one embodiment, the process of cycle queue adjustment is further included in the cached data block. Specifically, when the queue length is greater than 40, the queue position adjustment is performed according to the data block information corresponding to the data block in the cache queue, which includes the original transmission process of transmitting the data block. Exemplary, adjusting data blocks for the same transmission process into adjacent positions in the data block information.

[0074] In step S507, when the retransmission latency in a transmission process is greater than the data block transmission processing time, the data block is transmitted from the cache queue to the data block, according to the identification information of the data block to be transmitted. .

[0075] Step S508, the data block is transmitted in accordance with the packet sequentially, and the transmission time interval of each group data block is greater than the set time slot.

[0076] As can be seen from the above scheme, it is determined that the data application type of the currently transmitted data block is determined. The data application type is the type corresponding to the different application functions in the same application of the terminal device, and determines the corresponding identification information according to the data application type. The identification information is added to the data block, facilitating subsequent data block packets, and the determination of identification information is determined according to the data application type, the basis of the packet mode is better. At the same time, when it is detected that the currently created transmission process reaches the upper limit, the transfer data block is cached, and the location adjustment in the cache queue is periodically adjusted, and the allocation efficiency is improved, and each data block is separately judged. Assignment The process improves data transmission efficiency.

[0077] Figure 6 Another method of transmitting content changes in accordance with the feedback latency of the present invention, which gives a method of sequentially transmitting the packet according to the packet case. Such as Figure 6 As shown, the technical solution is as follows:

[0078] Step S601, determine the data application type of the currently transmitted data block, the data application type, corresponding to the type corresponding to the different application functions in the same application in the terminal device.

[0079] In step S602, the corresponding identification information is determined according to the data application type, and the identity information is added to the data block.

[0080]In step S603, during the data transmission process, determine the frame number information of the data block to be transmitted, determine the corresponding data check type according to the frame number information, and assigns a transmission process with the same data verification type for the transmission data block. .

[0081] In step S604, during the data transmission process, when a retransmission data instruction corresponding to a transmission process is detected, the number of retransmissions of the retransmission instruction correlation data is determined, and if the number of retransmission is greater than the first predetermined number of times, Then create a new transmission process for retransmission of the associated data.

[0082] Step S605, monitor the various transmission processes configured by the retransmission mechanism to determine the retransmission latency of each of the transmission processes.

[0083] Step S606, when detecting that the currently created transmission process reaches the upper limit, the transmission data block is cached, and the transmission data block in the cache queue is regularly adjusted periodically.

[0084] Step S607, when the retransmission latency in a transmission process is detected is greater than the data block transmission time, the data block is transmitted from the cache queue to the data block, according to the identification information of the data block to be transmitted. .

[0085] Step S608, determine the correlation degree of each packet data block, sorting according to the degree of correlation; the transmission of each group data block is sequentially based on the ordering result.

[0086] In one embodiment, the packet of the data block is performed according to the different data information type, and the correlation degree of each packet data block can be further determined after the re-group is completed. Specifically, the association degree of the data blocks for the same application is set to association, and the data blocks of the different applications are set to not associated. Exemplary, such as a total of 10 data blocks, which are 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:

[0087] Group 1 Group 2 Group 3 Group 4 Packet 5 Group 6 Group 7 Group 8 Group 9 Group 10 Program A Program B Program C Program B Program C Program A Program A Program B Program B Program C

[0088] After sorting the correlation, the group is as follows:

[0089] Group 1 Group 6 Group 7 Group 4 Group 2 Group 8 Group 9 Group 3 Packet 5 Group 10 Program A Program A Program A Program B Program B Program B Program C Program C Program C Program C

[0090] In the data block transmission, the transmission is performed according to the packet 1, packet 6, packet 7, packet 4, packet 2, packet 8, packet 9, packet 3, packet 5, and packet 10.

[0091] As can be known from the above scheme, by determining the correlation degree of each packet data block, sorting according to the correlation degree; according to the sorting result, the transmission of each group data block is sequentially processed, so that the transmission process is continuous or parallel to the associated data block. Further optimizing the data transmission mechanism.

[0092] On the basis of the above technical solution, the retransmission latency is adaptively adjusted according to the complexity of the link, and the adjustment step includes: initializing the quality variation parameters of the communication channel, transmitting a separate data frame to a plurality of terminal devices through the current transmission process, and is in Wait state, when the feedback information of the plurality of terminal devices is received, the transmission of the next data frame is performed according to the feedback information; the first communication signal transmitted by the first device is received, determines the first communication quality parameter, the phase separation After the time is set, the second communication signal transmitted by the second device is received, determine the second communication quality parameter, the first device, and the second device are the same different terminal device as the application type; according to the first communication quality parameter And the second communication quality parameter corrects the quality variation parameters, determines the retransmission latency according to the quality variation parameters.

[0093] In one embodiment, after determining the first communication quality parameter and the second communication quality parameter, the quality variation parameters are corrected according to the first communication quality parameters and the second communication quality parameters. Specifically, in order: the ratio of the second communication quality parameters and the first communication quality parameter, multiplied by the quality variation parameters obtained after initialization, the resulting result will be updated. Through the correction of the mass change parameters, it is not based on the change of the transmission mode based on the actual situation of a single channel, but is data update based on the change trend of the channel. After the quality change parameter is completed, the retransmission wait time is determined based on the corrected quality change parameter. When an exemplary, a mass change parameter is 35, the retransmission wait time can be 8s; when the quality variation parameter is 30, the first preset number may be 10s.

[0094] According to the above scheme, the value of the retransmission latency is adapted according to the quality variation parameter, so that the method of transmitting content changes according to the feedback latency can be adapted to adjust the retransmission wait time according to the link conditions to facilitate the subsequent accurate, Flexible change adjustment for transferring content.
