Therefore, when transmitting data in 4G/5G dual connection, it can be determined according to the respective channel quality proportional relationship. The proportion of data allocated for the connection and the data transferred by the 5G data connection. Although the transmission rate of 5G will be affected by the channel quality, the overall transmission rate is still higher than that of 4G. Therefore, according to the proportional relationship between the first channel quality and the second channel quality, the data transmitted according to the 4G data connection is 20% of the total data and 80% of the data transmitted through the 5G data connection determine the data distribution ratio between the 4G data connection and the 5G data connection: when the ratio between the quality of the first channel and the quality of the second channel is 3:2 , the data distribution ratio between 4G data connection and 5G data connection is 3:8; when the ratio between the first channel quality and the second channel quality is 1:5, the data distribution ratio between 4G data connection and 5G data connection is 1:20 ; When the proportional relationship between the first channel quality and the second channel quality is 3:4, the data allocation ratio of the 4G data connection and the 5G data connection is 3:16; the proportional relationship between the first channel quality and the second channel quality is 1: 1, the data allocation ratio of 4G data connection and 5G data connection is 1:4.

Table 1

S315. According to the data distribution ratio, transmit the target data through the 4G data connection and the 5G data connection.

Wherein, the target data refers to the information transmitted by the user through the data connection using the terminal.

Generally, after the terminal establishes a 4G data connection and a 5G data connection, and determines the data allocation ratio 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, the 4G data connection can be used to Connect with 5G data to transmit the target data that users want to transmit, improve the data transmission rate, and bring users a better online experience.
