Problems solved by technology

[0007] First, the sending mobile terminal needs to transfer all the files before informing the receiving mobile terminal to download, which cannot realize real-time file transmission;
[0008]Second, the transmitted files are kept on the file storage server, which is easy to leak or expose the user's personal privacy information, and the security is poor;
[0009]Third, because the transferred files need to be stored on the file storage server, if the user frequently transfers large-capacity files, it will occupy a large amount of storage space in the file storage. As a result, more disks are required to satisfy the service, and the cost is higher

Embodiment 1

[0050] In this embodiment, after receiving the file transfer request from the sender's mobile terminal, the receiver's mobile terminal applies for a file transfer channel to the file transfer server, and the file transfer server returns the channel information to the receiver's mobile terminal. The implementation process is shown in Figure 3, including the following steps:

[0051] Step 1: The sender's mobile terminal sends a file transfer request to the receiver's mobile terminal by means of an instant messaging message.

[0052] Step 2: The receiver's mobile terminal prompts the user whether to accept the file transmission, and if the user agrees to accept it, the receiver's mobile terminal sends a request to the file transfer server to apply for a file transmission channel;

[0053] Wherein, the request for applying for a file transmission channel carries the number of the mobile terminal of the sender and its own information. The self-information at least includes: its own...

Embodiment 2

[0065] In this embodiment, the sender's mobile terminal applies for a file transfer channel to the file transfer server, and the file transfer server returns channel information to the sender's mobile terminal.

[0066] The difference from Example 1 is:

[0067] In step 2, after the receiving user agrees to receive, the receiving user does not send a request to the file transfer server to apply for a file transmission channel, but returns a response of agreeing to receive to the sending mobile terminal through an instant messaging message. After receiving the response, the sending mobile terminal , sending a request for applying for a file transmission channel to the file transfer server, and the request carries the information of the sender’s mobile terminal and the receiver’s mobile terminal at the same time;

[0068] Correspondingly, step 3 becomes: after the file transfer server receives the request for applying for a file transmission channel, it verifies the information ...

Abstract

The invention discloses a realtime file transmission method, comprising: a file link server receives a request of applying a file transmission channel for the application mobile terminal; according to the received request, allocating file transmission channels and returning the channel information to the application mobile terminal; a send mobile terminal transmits the file blocks to the file link server through the file transmission channel, the file link server sends the file blocks to the application mobile terminal through the file transmission channel, a receiver mobile terminal receivesthe file blocks and generates a final file. The invention also discloses a realtime file transmission system, a file link server and a mobile terminal, the realtime file transmission between mobile terminals can be supported by the invention, the cost can be reduced greatly, safety and reliability of the file transmission can be improved.

Description

technical field [0001] The invention relates to a real-time file transmission technology, in particular to a method, system and device for real-time file transmission between mobile terminals using a wireless network. Background technique [0002] With the rapid development of wireless networks, the current wireless network has not only realized simple communication functions, but also can support data transmission and multimedia information transmission. In a wireless network, mobile terminals such as mobile phones can transfer files to each other in various ways, such as Bluetooth, infrared, MMS, etc. Different transmission methods support different transmission distances. Among them, the effective transmission range of Bluetooth The infrared transmission range is less than 1 meter. Therefore, the file transmission between long-distance mobile terminals will use the General Packet Radio Service (GPRS) network, or Code Division Multiple Access (CDMA), or the third generatio...
