Data transmission
First Claim
1. A method comprising:
- sending, by a sending terminal, data and a data identification corresponding to the data to a server; and
broadcasting the data identification to one or more receiving terminals through a short distance wireless communication protocol, wherein the data identification is generated based on multiple parameters including at least a short distance communication method identification of the short distance wireless communication, a random number, and a time length from a previous particular time to a current time.

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.
