Data transmission method and device and computer readable storage medium

The invention provides a data transmission method and device, and a computer readable storage medium. The method comprises the following steps: acquiring first communication data information; determining communication network information in the cellular communication network, and establishing a public key system model according to the communication network information and the public key facility system; performing asymmetric encryption processing on the first communication data information according to the public key system model to obtain a communication data ciphertext; constructing a communication data ciphertext model according to the communication data ciphertext; acquiring data features in the cellular communication network, and constructing a transmission rate analysis model according to the communication data ciphertext model and the data features; determining a data transmission rate in a transmission rate analysis model according to the data information acquisition probability threshold, the first b
