Detailed ways

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as an example, illustration or illustration. Any embodiments or designs described as "exemplary" or "such as" in the embodiments of the present invention should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present the related concepts in a specific manner.

In the description of the present invention, unless otherwise specified, "/" means "or", for example, A/B can mean A or B. In this article, "and/or" is only an association relationship to describe the associated objects, which means that there can be three kinds of relationships, for example, A and/or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone these three situations. Further, "at least one" and "plurality" refer to two or more. The words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit certain differences.

With the development of multimedia technology, some high-quality video and picture upload services require a large uplink rate support. For example, 8K video and machine vision services require gigabit uplink transmission. Insufficient, resulting in the inability to meet the user's uplink transmission requirements for services with a large amount of data.

In response to the demand for large uplink, a super uplink technical solution is proposed in the prior art. As shown in Figure 1, the super uplink mainly performs uplink on the frequency division duplexing (FDD) spectrum during the 3.5GHz downlink time slot. It can increase the time of uplink transmission, thereby improving the uplink throughput. Under the bandwidth of 100MHz, the single-point rate can be increased to 566Mbps.

In addition, the prior art also proposes a technical solution of "intelligent sharing and large uplink", as shown in FIG. 2 , through flexible time slots, carrier aggregation, multiple-input multiple-out-put (MIMO) The combination creates a large uplink network capability. Under the bandwidth of 100MHz, the single point rate can be increased to 1.2Gbps, and the cell capacity can reach 5Gbps.

Figure 3 shows a communication system in a 5G network, an image acquisition device such as a camera and a machine vision camera, and the upstream transmission process after video or image data is generated. As shown in FIG. 3 , in the communication system 10 , after the data source device 11 generates uplink data, it transmits the uplink data to the 5G base station 13 through the 5G terminal 12 , and the server 14 obtains the uplink data from the 5G base station 13 . The data source device 11 may be an image acquisition device such as a camera or a machine vision camera; the server 14 may be used to store uplink data, and may also be used to provide users with a download service of uplink data.

However, the above-mentioned image acquisition devices such as cameras and machine vision cameras generate a large amount of uplink data. For the code stream of high-definition video shown in Table 1 below, the amount of data generated by 8K high-definition video per second is 11Gbit. The code stream generated by a three-dimensional (3D) machine vision camera per second is more than 5Gbit.

Table 1: Video data information table

It can be seen that under the bandwidth of 100MHz, the super uplink technical solution proposed in the prior art can only increase the single point rate to 566Mbps, and the "smart sharing big uplink" technical solution can only increase the single point rate to 1.2Gbps, both of which It cannot meet the upstream transmission requirements of high-definition video and 3D machine vision.

In order to solve the above problems, the present invention provides a data transmission method, which is applied to a data transmission device. The data sending device acquires the target data to be transmitted in each transmission period, and divides the target data in each transmission period into a plurality of divided data. Further, the data sending device sends multiple offload data to the data receiving device through multiple target 5G terminals; the multiple offload data corresponds to the multiple target 5G terminals one-to-one. In the data transmission method provided by the present invention, after receiving the target data that needs to be transmitted upstream, the data transmission device distributes the target data to be transmitted, and cooperates with the upstream transmission through a corresponding number of multiple target 5G terminals to share the upstream transmission pressure, In this way, through the coordinated uplink transmission of multiple terminals, the user's uplink transmission requirements for large uplink services can be met.

As shown in FIG. 5 , the data transmission method provided by the embodiment of the present invention includes the following S301-S305.

S301. The data sending device acquires target data to be transmitted in each transmission period.

As a possible implementation manner, the data sending device obtains the data to be transmitted from the data source device. Further, the data sending device determines the target data to be transmitted in each transmission period from the to-be-transmitted data according to the transmission rate requirement of the to-be-transmitted data for each transmission period.

Exemplarily, the size of the transmission period may be 1 second. If the transmission rate requirement of the data to be transmitted for each transmission period is 5 Gbps, the data sending device determines the amount of data corresponding to the transmission rate of 5 Gbps from the acquired data to be transmitted. target data.

S302. The data sending device divides the target data in each transmission period into a plurality of divided data.

As a possible implementation manner, the data sending device determines the distribution ratio of the target data in each transmission period according to the number of target 5G terminals. Further, the data sending device divides the target data into a plurality of divided data according to the distribution ratio.

It should be noted that the target 5G terminal may be a 5G terminal that establishes a connection with the data transmission device, and the data transmission device may be determined as the number of target 5G terminals according to the number of 5G terminals connected to it.

In some embodiments, the offload ratio may be (1/the number of target 5G terminals), so that in the subsequent transmission process, the data volume of offload data transmitted by each target 5G terminal is the same, and the data volume of offload data is both Data volume of target data*(1/number of target 5G terminals).

Exemplarily, if the data sending device determines that the number of target 5G terminals is 5 and the data volume of the target data is 10 GB, then the data sending device determines that the split ratio is 1/5, and further splits the target data into 5 data volumes as 2GB of offloaded data.

It should be noted that, for how the data sending device specifically determines the number of target 5G terminals, reference may also be made to subsequent descriptions of the embodiments of the present invention, and details are not repeated here.

S303. The data sending device sends multiple offload data to the data receiving device through multiple target 5G terminals.

Among them, a plurality of offload data corresponds to a plurality of target 5G terminals one-to-one.

As a possible implementation, the data sending device transmits each of the multiple offloaded data to the corresponding target 5G terminal among the multiple target 5G terminals, and each target 5G terminal corresponds to one offloaded data, so that the Multiple offloaded data can be uplinked through multiple target 5G terminals and sent to the data receiving device.

Exemplarily, if the target 5G terminal includes 5 5G terminals, which are terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5, the target data split is 5 split data, which are data A, data B, Data C, Data D, and Data E. Then the data sending device can arbitrarily transmit data A to any 5G terminal among the five target 5G terminals, for example, it can be terminal 2. Further, the data sending device can arbitrarily transmit data B to the other four 5G terminals except terminal 2. Any 5G terminal in the terminal, for example, can be terminal 5, and so on, the final result of the data transmission device transmitting the offloaded data can be shown in Table 2 below, and each offloaded data is transmitted to a target 5G terminal respectively.

S304. The data receiving device receives multiple offload data sent by multiple target 5G terminals.

The multiple offload data is obtained by offloading the target data to be transmitted in each transmission period by the data sending device, and the multiple offload data corresponds to the multiple target 5G terminals one-to-one.

As a possible implementation manner, the data receiving device acquires multiple offload data sent by multiple target 5G terminals from the base station device.

S305 , the data receiving device merges multiple offloaded data to obtain target data in each transmission period.

As a possible implementation manner, after receiving multiple offloaded data, the data receiving device sorts and reorganizes the multiple offloaded data according to the timestamp information of each offloaded data, and then obtains the data sent by the data sending device during the transmission period. target data.

In one design, in order to make full use of the transmission capability of the 5G terminal, as shown in FIG. 6 , the data transmission method provided by the embodiment of the present invention further includes S401-S402.

S401. The data sending device obtains the average transmission capability of multiple 5G terminals.

As a possible implementation manner, the data sending device obtains the transmission capability of each 5G terminal in the multiple 5G terminals, and then determines the average transmission capability of the multiple 5G terminals.

It should be noted that the transmission capability of the 5G terminal may be determined according to the model of the 5G terminal or historical transmission data, which is not limited in this embodiment of the present invention.

S402. The data sending device determines a plurality of target 5G terminals based on the ratio of the transmission rate requirement and the average transmission capacity.

Wherein, the difference between the number of multiple target 5G terminals and the ratio is greater than or equal to a preset threshold.

As a possible implementation, after determining the ratio of the transmission rate requirement to the average transmission capacity, the data sending device will add the value obtained by adding the preset threshold on the basis of the ratio to determine the number of multiple target 5G terminals , and determine a corresponding number of multiple target 5G terminals from multiple 5G terminals.

Exemplarily, assuming that the transmission rate requirement determined by the data transmission device is data, the average transmission capability of the 5G terminal is TH _AV , and the preset threshold is 1, then the number N of target 5G terminals determined by the data transmission device can be used as follows: Public 1 gets.

In some embodiments, when the ratio between the transmission rate requirement and the average transmission capacity determined by the data sending device is not an integer, the data sending device first rounds up the ratio and adds a preset threshold to obtain multiple targets The number of 5G terminals.

Exemplarily, if the ratio of the transmission rate requirement to the average transmission capacity determined by the data sending device is 4.7, and the preset threshold is 1, the data sending device first rounds up to obtain 5, and then adds the preset threshold of 1 to obtain multiple The number of target 5G terminals is 6, and from the multiple 5G terminals, 6 target 5G terminals are determined for uplink transmission in the subsequent transmission process.

It is understandable that the above-mentioned data sending device determines the number of target 5G terminals based on the transmission rate requirement and average capability, which can make full use of the transmission capacity of 5G terminals, and add a preset threshold on this basis to avoid multiple target 5G terminals. Among them, there are many 5G terminals that cannot reach the average transmission capacity, resulting in the situation that the transmission rate cannot be met.

It should be noted that the preset threshold may be pre-set in the data sending device by the operation and maintenance personnel of the data sending device.

In one design, after the end of the previous transmission cycle, and there is remaining data that has not been transmitted in the transmission result of the previous transmission cycle, in order to avoid the situation of remaining data in the subsequent transmission process, as shown in Figure 7 As shown, the data transmission method provided by the embodiment of the present invention further includes S501-S503.

Wherein, the first 5G terminal includes a 5G terminal corresponding to the remaining data among the multiple target 5G terminals;

As a possible implementation manner, the data sending device obtains the transmission result of each target 5G terminal after the end of the previous transmission period. Further, the data sending device determines, from the transmission result, the first 5G terminal that has not completed the offload data transmission, and determines the transmitted data volume of the first 5G terminal according to the data volume of the offload data minus the data volume of the unfinished transmission, The amount of transmitted data is determined as the maximum transmission capability of the first 5G terminal.

It should be noted that the above transmission result includes the target 5G terminal and the corresponding buffered data amount.

Exemplarily, if the transmission result is shown in Table 3 below, the data sending device determines that terminal 1 and terminal 3 are the first 5G terminals. Further, if the data volume of the offloaded data is 2 GB, the data sending device determines that the maximum transmission capacity of the terminal 1 is 1.7 GB, and the maximum transmission capacity of the terminal 3 is 1.9 GB.

Table 3: Terminal Data Cache Table

Target 5G terminal The amount of cached data Terminal 1 0.3GB Terminal 2 0GB Terminal 3 0.1GB Terminal 4 0GB Terminal 5 0GB

S502. The data sending device determines the offload data corresponding to the first 5G terminal from the target data of the current transmission period according to the maximum transmission capability of the first 5G terminal.

As a possible implementation manner, the data sending device determines data matching the maximum transmission capability of the first 5G terminal from the target data of the current transmission cycle according to the maximum transmission capability of the first 5G terminal determined in the above step S501 amount of diversion data. Further, the data sending device transmits the offloaded data to the first 5G terminal, and the first 5G terminal performs uplink transmission of the offloaded data in the subsequent process.

Exemplarily, if the data volume of the target data in the current transmission cycle is 10 GB, and based on the above Table 3, the maximum transmission capacity of terminal 1 is 1.7 GB, and the maximum transmission capacity of terminal 3 is 1.9 GB, then the data sending device is the terminal. 1 offloads the offloaded data with a data volume of 1.7GB, and offloads the offloaded data with a data volume of 1.9GB for the terminal 3.

S503: The data sending device offloads the unoffloaded data according to the number of the second 5G terminals.

Wherein, the second 5G terminal includes 5G terminals other than the first 5G terminal among the multiple target 5G terminals; the undistributed data includes data in the target data other than the distributed data corresponding to the first 5G terminal.

As a possible implementation manner, the data sending device determines the number of the second 5G terminals based on the number of multiple target 5G terminals and the number of the first 5G terminals. Further, according to the number of the second 5G terminals, the data sending device offloads the unoffloaded data.

It should be noted that, for the specific method of how the data sending device performs offloading of unoffloaded data according to the number of second 5G terminals, reference may be made to the above step S302 in the embodiment of the present invention, where the data sending device sends the target data to the target data according to the number of target 5G terminals. The method for shunting is not repeated here.

In one design, after the end of the previous transmission period and there is remaining data in the transmission result, in order to complete the transmission of the remaining data in the previous transmission period in the current transmission period, as shown in FIG. The data transmission method provided by the embodiment further includes S601-S602.

S601. For the current transmission period, the data sending device determines the remaining data.

As a possible implementation manner, after the end of the previous transmission period, the data sending device obtains the buffer of uplink transmission of each target 5G terminal among the multiple target 5G terminals. Further, the data sending device determines the remaining data according to the upstream transmission buffer of each target 5G terminal.

Exemplarily, as shown in Table 3 above, the data sending device obtains the upstream transmission buffers of 5 target 5G terminals, and determines that the buffer to terminal 1 is 0.3 GB, the buffer of terminal 3 is 0.1 GB, and the buffer of terminal 2, terminal 4 and terminal 4 is determined to be 0.3 GB. 5 has a cache of 0GB. Further, the data sending device determines that the remaining data is 0.3 GB of offload data that has not been transmitted by terminal 1 and 0.1 GB of offloaded data that has not been transmitted by terminal 3 .

S602. The data sending device offloads the remaining data to the second 5G terminal, and sends the remaining data to the data receiving device through the second 5G terminal.

As a possible implementation, the data sending device divides the remaining data according to the number of the second 5G terminals, and transmits the remaining data after the distribution to the second 5G terminal respectively, and performs uplink transmission through the second 5G terminal, and sends the data to the second 5G terminal. The receiving device sends the remaining data.

Exemplarily, if the number of target 5G terminals is N, in the last transmission period, the buffers for uplink transmission of the M first 5G terminals are respectively C ₁ , C ₂ , ... , C _M , and K second 5G terminals 1,2,…,K, respectively. On this basis, the data sending device may use the following formula 2 to determine the data amount ΔTH _k1 of the remaining data to be offloaded for each second 5G terminal.

In some embodiments, if the second 5G terminal indicates that the second 5G terminal has remaining data in the transmission result after the current transmission period ends, the data sending device further performs the above steps S601-S602 in the second 5G terminal, In order to gradually balance the transmission capacity of the 5G terminal with the amount of data to be distributed, and to complete the uplink transmission of the target data in the current transmission cycle.

The data sending device acquires the target data to be transmitted in each transmission period, and divides the target data in each transmission period into multiple divided data; the transmission rate requirement of each transmission period is greater than that. Further, the data sending device sends multiple offload data to the data receiving device through multiple target 5G terminals; the multiple offload data corresponds to the multiple target 5G terminals one-to-one. In the data transmission method provided by the present invention, after receiving the target data that needs to be transmitted upstream, the data transmission device distributes the target data to be transmitted, and cooperates with the upstream transmission through a corresponding number of multiple target 5G terminals to share the upstream transmission pressure, In this way, through the coordinated uplink transmission of multiple terminals, the user's uplink transmission requirements for large uplink services can be met.
