Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
In the present embodiments, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the present invention, "/" means "or" unless otherwise specified, for example, A/B may mean A or B. "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. Further, "at least one" or "a plurality" means two or more. The terms "first," "second," and the like do not denote any order or importance, but rather the terms "first," "second," and the like do not denote any order or importance.
With the development of multimedia technology, some high-quality video and picture uploading services need a larger uplink rate support, for example, services such as 8K video and machine vision provide a gigabit demand for uplink transmission, but due to the lack of the current uplink capacity, the uplink transmission demand of users for large data volume services cannot be met.
For the requirement of large uplink, a super uplink technical scheme is proposed in the prior art, as shown in fig. 1, the super uplink mainly performs uplink transmission on a Frequency Division Duplex (FDD) spectrum during a 3.5GHz downlink timeslot, and increases the time of uplink transmission, thereby increasing the uplink throughput, and increasing the single-point rate to 566Mbps under a bandwidth of 100 MHz.
In addition, a technical scheme of "intelligent shared large uplink" is also proposed in the prior art, as shown in fig. 2, a large uplink network capability is created by combining flexible time slots, carrier aggregation, and multiple-input multiple-output (MIMO), so that a single-point rate can be increased to 1.2Gbps under a bandwidth of 100MHz, and a cell capacity can reach 5 Gbps.
Fig. 3 shows an uplink transmission flow after video or image data is generated by an image capturing device such as a video camera or a machine vision camera in a 5G network. As shown in fig. 3, in the communication system 10, after generating uplink data, the data source device 11 transmits uplink data to the 5G base station 13 through the 5G terminal 12, and the server 14 acquires the uplink data from the 5G base station 13. The data source device 11 may be an image acquisition device such as a video camera, a machine vision camera, or the like; server 14 may be used to store upstream data and may also be used to provide a download service for upstream data to users.
However, the data volume of the uplink data generated by the image capturing device such as the video camera and the machine vision camera is large, and the data volume generated by the 8K high definition video per second is 11Gbit as the code stream of the high definition video shown in table 1 below. The code stream generated by a three-dimensional (3D) machine vision camera per second is more than 5 Gbit.
Table 1: video data information table
Therefore, under the bandwidth of 100MHz, the super uplink technical scheme proposed in the prior art can only increase the single-point rate to 566Mbps, and the "smart big uplink" technical scheme can only increase the single-point rate to 1.2Gbps, which cannot meet the uplink transmission requirements of high-definition video and 3D machine vision.
In order to solve the above problem, the present invention provides a data transmission method applied to a data transmission device. The data sending equipment acquires 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 a plurality of split data to the data receiving device through a plurality of target 5G terminals; the plurality of split data correspond to the plurality of target 5G terminals one to one. In the data transmission method provided by the invention, after receiving the target data needing uplink transmission, the data sending equipment distributes the target data to be transmitted, and the target data is cooperatively uplink-transmitted through a plurality of target 5G terminals in a corresponding quantity, so that the uplink transmission requirement of a user on a large uplink service can be met through cooperative uplink transmission of a plurality of terminals.
Referring to fig. 4, the data transmission method may be applied to the communication system 20 shown in fig. 4. As shown in fig. 4, the communication system 20 includes a data source device 21, a data transmission device 22, a plurality of 5G terminals 23, a base station device 24, a data reception device 25, and a server 26.
The data source device 21 may be an image collecting device such as a video camera or a machine vision camera, and is configured to provide target data to be transmitted for the data sending device 22.
The data sending device 22 may be configured to split target data to be transmitted, which is provided by the data source device 21, to obtain split data. The data sending device 22 may also be configured to send the split data to the data receiving device 25 through the plurality of 5G terminals 23.
In some embodiments, the data source device 21 and the data sending device 22 are connected by a wired connection, and the data source device 21 sends target data to be transmitted to the data sending device 22 by wired transmission.
The 5G terminal 23 may be configured to send the split data to the data receiving device 25 through the base station device 24 after receiving the split data sent by the data sending device 22.
In some embodiments, the 5G terminal 23 may be replaced with a Customer Premise Equipment (CPE), and the upstream transmission of the plurality of split data is completed by a plurality of CPEs.
The base station device 24 may be used to provide network services for the 5G terminal 23.
The data receiving device 25 may be configured to, after receiving the split data sent by the data sending device 22 through the base station device 24, combine the split data to obtain target data before splitting, and send the target data to the server 26. The data receiving apparatus 25 may be disposed in the base station apparatus 24, and may also be disposed in the server 26.
Fig. 5 is a flow diagram illustrating a method of data transmission, according to some example embodiments. In some embodiments, the above-described data transmission method may be applied in the communication system 20 as shown in fig. 4. Hereinafter, the data transmission method according to the embodiment of the present invention is applied to the communication system 20, and the data transmission method will be described.
As shown in fig. 5, the data transmission method provided in the embodiment of the present invention includes the following steps S301 to S305.
S301, the data sending equipment obtains target data to be transmitted in each transmission period.
As a possible implementation manner, the data sending device obtains data to be transmitted from the data source device. Further, the data sending device determines target data to be transmitted in each transmission period from the data to be transmitted according to the transmission rate requirement of the data to be transmitted for each transmission period.
For example, the size of the transmission cycle may be 1 second, and if the transmission rate requirement of the data to be transmitted for each transmission cycle is 5Gbps, the data sending device determines, from the obtained data to be transmitted, target data of a data volume corresponding to the transmission rate of 5 Gbps.
S302, the data sending equipment 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 split ratio of the target data in each transmission period according to the number of the target 5G terminals. Further, the data sending device divides the target data into a plurality of divided data according to the division ratio.
It should be noted that the target 5G terminals may be 5G terminals that establish connection with the data sending device, and the data sending device may determine the number of the target 5G terminals according to the number of the 5G terminals connected to the data sending device.
In some embodiments, the split ratio may be (1/the number of the target 5G terminals), so that in the subsequent transmission process, the data amount of the split data transmitted by each target 5G terminal is the same, and the data amount of the split data is the data amount of the target data × 1 (the number of the target 5G terminals).
For example, if the data sending device determines that the number of the target 5G terminals is 5 and the data size of the target data is 10GB, the data sending device determines that the splitting ratio is 1/5, and further splits the target data into 5 pieces of split data with a data size of 2 GB.
It should be noted that, how the data sending device specifically determines the number of the target 5G terminals may also refer to the subsequent description of the embodiment of the present invention, and details are not described here again.
S303, the data sending device sends the multiple pieces of split data to the data receiving device through the multiple target 5G terminals.
The plurality of shunt data correspond to the plurality of target 5G terminals one to one.
As a possible implementation manner, the data sending device respectively transmits each of the plurality of pieces of shunt data to a corresponding target 5G terminal of the plurality of target 5G terminals, where each target 5G terminal corresponds to one piece of shunt data, so that the plurality of pieces of shunt data can be transmitted uplink by the plurality of target 5G terminals and sent to the data receiving device.
Illustratively, if the target 5G terminal includes 5G terminals, which are terminal 1, terminal 2, terminal 3, terminal 4 and terminal 5, respectively, the target data is split into 5 split data, which are data a, data B, data C, data D and data E, respectively. Then the data sending device may transmit the data a to any 5G terminal of the 5 target 5G terminals, for example, to the terminal 2, further, the data sending device transmits the data B to any 5G terminal of the 4 other 5G terminals except the terminal 2, for example, to the terminal 5, and so on, and the final result of the data sending device transmitting the split data may be as shown in table 2 below, and each split data is transmitted to one target 5G terminal respectively.
Table 2: shunting data transmission table
| Offloading data | Target 5G terminal |
| Data A | Terminal 2 |
| Data B | Terminal 5 |
| Data C | Terminal 1 |
| Data D | Terminal 4 |
| Data E | Terminal 3 |
S304, the data receiving equipment receives a plurality of shunt data sent by a plurality of target 5G terminals.
The split data are obtained by splitting target data to be transmitted in each transmission period through data sending equipment, and the split data correspond to the target 5G terminals one to one.
As a possible implementation manner, the data receiving device obtains, from the base station device, multiple pieces of offload data sent by multiple target 5G terminals.
S305, the data receiving device merges the multiple split data to obtain target data in each transmission cycle.
As a possible implementation manner, after receiving multiple pieces of split data, the data receiving device sequences and reassembles the multiple pieces of split data according to timestamp information of each piece of split data, so as to obtain target data sent by the data sending device in a transmission cycle.
In one design, in order to fully utilize the transmission capability of the 5G terminal, as shown in fig. 6, the data transmission method provided in the embodiment of the present invention further includes S401 to S402.
S401, the data sending equipment obtains average transmission capacity of a plurality of 5G terminals.
As a possible implementation manner, the data sending device obtains the transmission capability of each 5G terminal in the plurality of 5G terminals, and further determines the average transmission capability of the plurality of 5G terminals.
It should be noted that the transmission capability of the 5G terminal may be determined according to the model or the historical transmission data of the 5G terminal, which is not limited in the embodiment of the present invention.
S402, the data sending equipment determines a plurality of target 5G terminals based on the ratio of the transmission rate requirement to the average transmission capacity.
And the difference between the number of the plurality of target 5G terminals and the ratio is greater than or equal to a preset threshold value.
As a possible implementation manner, after determining the ratio of the transmission rate requirement to the average transmission capability, the data sending device determines, as the number of the plurality of target 5G terminals, a numerical value obtained by adding a preset threshold to the ratio, and determines a plurality of target 5G terminals of a corresponding number from the plurality of 5G terminals.
Exemplarily, the transmission rate requirement determined by the data sending device is data, and the average transmission capability of the 5G terminal is TH AV If the preset threshold is 1, the number N of the target 5G terminals determined by the data transmission device may be obtained by using the following equation 1.
In some embodiments, when the ratio of the transmission rate requirement determined by the data sending device to the average transmission capability is not an integer, the data sending device first rounds the ratio up, and adds a preset threshold to obtain the number of the target 5G terminals.
Illustratively, if the ratio of the transmission rate requirement determined by the data sending device to the average transmission capacity is 4.7, and the preset threshold is 1, the data sending device first rounds to obtain 5, and then adds the preset threshold 1 to obtain that the number of the target 5G terminals is 6, and then determines 6 target 5G terminals from the plurality of 5G terminals for uplink transmission in the subsequent transmission process.
It can be understood that, the data sending device determines the number of the target 5G terminals based on the transmission rate requirement and the average capability, and can make full use of the transmission capability of the 5G terminals, and on this basis, adds the preset threshold value, so as to avoid the situation that, if there are a plurality of target 5G terminals, there are more 5G terminals that cannot achieve the average transmission capability, and the transmission rate requirement cannot be met.
It should be noted that the preset threshold may be set in the data sending device in advance by an operation and maintenance person of the data sending device.
In one design, after the last transmission cycle is ended and when there is remaining data that has not been transmitted in the transmission result of the last transmission cycle, in order to avoid the remaining data in the subsequent transmission process, as shown in fig. 7, the data transmission method provided in the embodiment of the present invention further includes S501-S503.
S501, for the current period, the data transmission device determines the maximum transmission capability of the first 5G terminal.
The first 5G terminal comprises a plurality of target 5G terminals and a first 5G terminal corresponding to the residual data;
as a possible implementation manner, after the last transmission period is ended, the data sending device obtains the transmission result of each target 5G terminal. Further, the data sending device determines, from the transmission result, a first 5G terminal that does not complete transmission of the split data, determines a transmitted data amount of the first 5G terminal by subtracting the unfinished transmission data amount from the data amount of the split data, and determines the transmitted data amount as the maximum transmission capability of the first 5G terminal.
It should be noted that the transmission result includes the target 5G terminal and the corresponding buffer data amount.
For example, if the transmission result is shown in table 3 below, the data transmission device determines that the terminal 1 and the terminal 3 are the first 5G terminals. Further, if the data volume of the split data is 2GB, the data sending device determines that the maximum transmission capability of the terminal 1 is 1.7GB, and the maximum transmission capability of the terminal 3 is 1.9 GB.
Table 3: terminal data cache table
| Target 5G terminal | Amount of buffered data |
| Terminal 1 | 0.3GB |
| Terminal 2 | 0GB |
| Terminal 3 | 0.1GB |
| Terminal 4 | 0GB |
| Terminal 5 | 0GB |
And S502, the data sending equipment determines the shunt 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, according to the maximum transmission capability of the first 5G terminal determined in step S501, split data of a data size that matches the maximum transmission capability of the first 5G terminal from the target data of the current transmission cycle. Further, the data sending device transmits the split data to the first 5G terminal, and the first 5G terminal performs uplink transmission of the split data in a subsequent process.
For example, if the data size of the target data of the current transmission cycle is 10GB, on the basis of table 3, the maximum transmission capability of the terminal 1 is 1.7GB, and the maximum transmission capability of the terminal 3 is 1.9GB, the data sending device shunts the shunted data of the data size of 1.7GB for the terminal 1, and shunts the shunted data of the data size of 1.9GB for the terminal 3.
