DATA TRANSMISSION METHOD AND SYSTEM, TERMINAL THEREOF

摘要

A data transmission method is provided in the present invention. The method includes the following steps: A. receiving a data resource issuing request issued by a data resource issuing terminal, and notifying the downloading terminals according to the request (S10); B. according to the notification, establishing the network connections between the data resource issuing terminal and each downloading terminal, and the network connections among the downloading terminals (S20); C. establishing the broadcast channels according to the network connections (S30); D. establishing the data links according to the established broadcast channels, and transmitting the data resources via the data links (S40). Furthermore, a data transmission system and terminal are also provided. The data transmission method, system and terminal can decrease the bandwidth cost, will not have errors due to the breakdown of one broadcast channel, and can also decrease the bit error rate.
