Abstract

The invention discloses a method for transmitting a file between terminal devices, a terminal device and a file transmission system. The method comprises following steps of establishing a first transmission link with a server; searching whether an objective terminal device is in own local area network or not when a to-be-transmitted file is sent to an objective terminal device; establishing a second transmission link with the objective terminal device if there is the objective terminal device; sending the to-be-transmitted file to the objective terminal device through the second transmission link; sending the to-be-transmitted file to the server through the first transmission link if there is no objective terminal device; and forwarding the to-be-transmitted file to the objective terminal device by the server through a third transmission link established between the server and the objective terminal device. Through adoption of the mode, the transmission speed of transmitting the to-be-transmitted file between the terminal devices can be improved.

Description

technical field

[0001] The invention relates to the technical field of data transmission, in particular to a method for transmitting files between terminal devices, a terminal device and a file transmission system. Background technique

[0002] With the development of smart phones, the functions of smart phones are becoming more and more powerful, their capacity is getting larger and larger, and the types of stored files are also increasing. Smart phones often need to exchange files with other smart phones or computers to achieve file sharing or collaborative office.

[0003] In the prior art, the ways of transferring files between smartphones include bluetooth transmission and computer relay transmission. Bluetooth transmission means that two smart phones are directly connected by Bluetooth, and then wirelessly transmitted through Bluetooth, but Bluetooth transmission only allows point-to-point transmission, and the connection distance allowed by Bluetooth is also very sho...
