Abstract
Methods, apparatuses, and systems for data transmission are described. A sending terminal sends data and a data identification of the data to a server. The data identification is broadcasted to one or more receiving terminals through a short distance wireless communication. The receiving terminal obtains the data from the server according to the data identification. When the sending terminal needs to transmit data to multiple receiving terminals, the techniques of the present disclosure do not require the sending terminal to establish a point-to-point connection with each of the receiving terminal. Thus, the techniques of the present disclosure effectively reduce transmission time with multiple receiving terminals, improve data transmission efficiency, and lower power consumption at the sending terminal.
