Generally, when a terminal supporting 5G is in a 5G serving cell, because the coverage area of the 5G serving cell is limited, the locations of the terminals in the 5G serving cell are different, and the strength of the 5G signal that can be received is also different, it is necessary to obtain the location of the 5G serving cell where the terminal resides, and measure the strength of the 5G signal where the terminal resides in the 5G serving cell.
S202, when the 5G signal strength is smaller than the first signal strength threshold and larger than or equal to the second signal strength threshold, establishing 5G data connection through the 5G service cell.
The threshold value is also referred to as a critical value, and refers to a minimum value or a maximum value that can be generated by an effect, in this embodiment of the present application, the first signal strength threshold value refers to a lower limit value set in the terminal and having a stronger 5G signal, when the actual 5G signal strength is greater than or equal to the first signal strength threshold value, it indicates that the 5G signal is better at this time, and the terminal can smoothly transmit data through the 5G network; the second signal strength threshold is an upper limit value of weaker 5G signals set in the terminal, and when the actual 5G signal strength is smaller than the second signal strength threshold, the fact that the 5G signals are worst at the moment is indicated, and the terminal transmits data through a 5G network to cause data loss; the first signal strength threshold is greater than the second signal strength threshold. The 5G data connection refers to a manner in which a terminal supporting 5G can perform 5G network communication.
Generally, after measuring the 5G signal strength of the 5G serving cell in which the terminal is located, the relationship between the 5G signal strength and the first and second signal strength thresholds needs to be analyzed to determine the type of data connection establishment: when the 5G signal strength is greater than or equal to a second signal strength threshold, establishing 5G data connection through a 5G service cell; searching for a 4G serving cell when the 5G signal strength is less than the second signal strength threshold, and establishing a 4G data connection through the 4G serving cell.

The 4G service cell refers to a region in which the terminal can obtain 4G network service, is a cell divided from the whole 4G communication service region, is provided with a 4G base station, is responsible for establishing wireless connection with the terminal in the cell, and supports 4G communication of the 4G terminal in any cell in the 4G communication service region. The 4G data connection refers to a manner in which a terminal supporting 4G can perform 4G network communication.
Generally, when it is determined that the 5G signal strength of the 5G serving cell in which the terminal is located is smaller than the first signal strength threshold and greater than or equal to the second signal strength threshold, it indicates that the current 5G signal is medium, after a 5G data connection is established through the 5G serving cell, the terminal may cause data loss by transmitting data through the 5G data connection, and the terminal needs to be protected to smoothly complete data transmission by transmitting data through the 4G data connection at the same time; therefore, it is necessary to search for a further 4G serving cell, select a cell having the greatest 4G signal strength as a 4G serving cell when a plurality of 4G cells are searched, and establish a 4G data connection through the 4G serving cell.

In general, after a terminal establishes a 4G data connection and a 5G data connection, target data that a user wants to transmit can be transmitted through the 4G data connection and the 5G data connection.
As can be seen from the foregoing, in the data transmission method provided by the present embodiment, the terminal may measure the 5G signal strength of the 5G serving cell, and when the 5G signal strength is smaller than the first signal strength threshold and greater than or equal to the second signal strength threshold, establish a 5G data connection through the 5G serving cell, search for a 4G serving cell, and establish a 4G data connection through the 4G serving cell, and transmit target data through the 4G data connection and the 5G data connection, so that the terminal can transmit data simultaneously through the 4G network and the 5G network when the 5G signal is weak, thereby avoiding the problem of loss of the transmitted data.

In general, a terminal measures quality information of a 5G service cell according to a measurement configuration message sent by a network device and reports the quality information to the network device; when the terminal is switched to a new 5G service cell, the measurement before the terminal is not applicable any more, and the network equipment needs to instruct the terminal to perform new measurement according to the states of the new 5G service cell and the neighboring cell so as to realize the management of the connection state mobility of the terminal. The measurement control of the network equipment to the terminal is mainly realized by sending measurement control information to the terminal, and when the terminal finishes measurement, a measurement report is generated and reported to the network equipment, so that the acquisition of parameters and the monitoring of the state of the terminal side by the network equipment are realized. The period of reporting measurement reports is fixed during the network device initiated measurement process.

S305, the target data is transferred only through the 5G data connection.
The target data refers to information transmitted by a user through data connection by using a terminal.

Generally, when the 4G signal strength is greater than or equal to the third signal strength threshold, the fact that the 4G signal is good at this time indicates that the terminal can smoothly transmit data through the 4G network, 4G data connection is established under the condition that the 5G signal strength is poor and the 4G signal strength is good, data transmission through the 4G data connection can ensure that the data required to be transmitted by a user is not lost, and the Internet surfing experience of the user is improved; when the 4G signal strength is smaller than a third signal strength threshold, the terminal needs to determine the strength of the 4G signal strength and the 5G signal strength at the moment, and if the 4G signal strength is greater than the 5G signal strength, 4G data connection is selected to be established; if the 4G signal strength is weaker than the 5G signal strength, a 5G data connection is selected to be established.
S309, the target data is transferred only through the 4G data connection.

In general, the maximum data amount that can be borne by the 4G data connection and the 5G data connection is different due to different channel qualities, so that the data distribution ratio can be determined according to the proportional relationship between the first channel quality of the 4G data connection and the second channel quality of the 5G data connection, and the data amount transmitted through the 4G data connection and the 5G data connection is reasonably distributed according to the target data to be transmitted, so that the target data can be quickly transmitted, and the channel utilization rate of the 4G data connection and the 5G data connection is improved.
For example, referring to the relationship mapping table in table 1, the data allocation ratio of the 4G data connection and the 5G data connection is determined according to the ratio relationship between the first channel quality of the 4G data connection and the second channel quality of the 5G data connection, and the data allocation ratio of the 4G data connection and the 5G data connection can be determined according to the respective ratio relationship when the 4G/5G dual connection is transmitting data because the 5G transmission rate is far higher than the 4G transmission rate but the 5G transmission rate is affected by the channel quality. Although the transmission rate of 5G will be affected by the channel quality, the overall transmission rate is still higher than that of 4G, so the data allocation proportionality relationship between the 4G data connection and the 5G data connection is determined according to the proportionality relationship between the first channel quality and the second channel quality, and according to the data transmitted by the 4G data connection being 20% of the total data and the data transmitted by the 5G data connection being 80% of the total data: when the ratio relation between the first channel quality and the second channel quality is 3:2, the data distribution ratio of the 4G data connection and the 5G data connection is 3:8; when the proportional relation between the first channel quality and the second channel quality is 1:5, the data distribution ratio of the 4G data connection and the 5G data connection is 1:20; when the ratio relation between the first channel quality and the second channel quality is 3:4, the data distribution ratio of the 4G data connection and the 5G data connection is 3:16; when the ratio relation between the first channel quality and the second channel quality is 1:1, the data distribution ratio of the 4G data connection and the 5G data connection is 1:4.
TABLE 1
S315, transmitting target data through the 4G data connection and the 5G data connection according to the data distribution proportion.

As can be seen from the foregoing, in the data transmission method provided by the present embodiment, the terminal receives a measurement configuration message sent by the network device, measures the 5G serving cell according to the measurement configuration message to obtain a measurement report, where the measurement report includes 5G signal strength of the 5G serving cell, determines whether the 5G signal strength is greater than or equal to a first signal strength threshold, and if the 5G signal strength is greater than or equal to the first signal strength threshold, establishes 5G data connection through the 5G serving cell, and only transmits target data through the 5G data connection; judging whether the 5G signal strength is smaller than a second signal strength threshold, if the 5G signal strength is smaller than the second signal strength threshold, searching a 4G serving cell, and measuring the 4G signal strength of the 4G serving cell; when the 4G signal strength is greater than or equal to a third signal strength threshold, establishing 4G data connection only through the 4G service cell, and transmitting target data only through the 4G data connection; if the 5G signal strength is smaller than the first signal strength threshold and larger than or equal to the second signal strength threshold, establishing 5G data connection through a 5G service cell, searching a plurality of 4G cells, selecting a cell with the largest 4G signal strength as the 4G service cell, establishing 4G data connection through the 4G service cell, acquiring first channel quality of the 4G data connection, acquiring second signal quality of the 5G data connection, determining a data distribution proportion according to a proportion relation between the first channel quality and the second channel quality, and transmitting target data through the 4G data connection and the 5G data connection according to the data distribution proportion. By the method, the terminal can select a mode of transmitting data through the 4G data connection and the 5G data connection or transmitting data only through the 4G data connection when the 5G signal is not good, so that the data which a user needs to transmit is not easy to lose, and the Internet surfing experience of the user is improved.
