Abstract:
Disclosed are a data transmission method, device and system, falling within the technical field of communications. The method comprises: receiving a data packet sent by a user equipment, wherein the data packet carries indication information, and the indication information is used for instructing a base station to establish a designated data connection with the user equipment; generating a first key of the user equipment according to the indication information and a public key of the base station; and performing data transmission with the user equipment based on the first key of the user equipment. By means of this data transmission method, where there is no wireless resource control connection between a base station and a user equipment, transmitted data can be encrypted and decrypted, thereby improving the security of data transmission on the basis of guaranteeing data transmission efficiency.
