Intelligent transmission link selection method and system

The invention relates to the technical field of communication and discloses an intelligent transmission link selection system. The intelligent transmission link selection system comprises a network transmission module and a main intelligent transmission link selection system, wherein the network transmission module is used for data interaction between a user terminal and a network end, the main intelligent transmission link selection system comprises a transmission link detection module and a transmission link selection module, the transmission link detection module is used for detecting the condition of each transmission link, the transmission link selection module is used for selecting an appropriate transmission link, and data of the user terminal or the network end are transmitted through the selected appropriate transmission link. Due to the fact that the transmission link which is strong in signal or small in number of data packets to be transmitted is selected from all the transmission links for data transmission, stability and reliability of data transmission are improved.
