The invention relates to a multi-link concurrent access multimedia data transmission method. The present method that using a single operator to provide transmission bandwidth can not support the high quality and real time transmission of multimedia service. The invention provides a multi-link concurrent access multimedia data transmission method which includes the server information acquisition, the segmentation of the data to be transmitted, the data transmission, and priority distinguished data transmission and data protection. Wherein, the data transmission includes an alternative test cycle and a data cycle; in the test cycle, the transmitting equipment test the performance of the data transmission link and the access link; in the data cycle, the transmitting equipment transmits data at each link according to the test result of the test cycle, thereby making full use of the link bandwidth resource and avoiding the link congestion. The multi-link concurrent access multimedia data transmission method of the invention adopts the transmission type by distinguishing the priority of different data at different priority; thereby ensure the transmission reliability of the high priority data.
