Embodiment Construction

[0018] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0019] A file transfer method for a mobile terminal, comprising the following steps:

[0020] a. The sender of the mobile terminal creates a WIFI hotspot, generates a hotspot name, and waits for a connection request;

[0021] b. The receiver of the mobile terminal searches for surrounding WIFI hotspots, and after finding the target WIFI hotspot, sends a connection request to the target WIFI hotspot, and encrypts the connection request with the WAP-PSK encryption standard. After receiving the connection request, the sender of the mobile terminal starts an independent service socket message center;

[0022] c. The receiving party of the mobile terminal starts the receiving file server;

[0023] d. The sender of the mobile terminal starts the file sending task, sends the file to the receiver of the mobile terminal, and completes the file transfer.

[0024] In the abov...

Abstract

The invention provides a file transmission method for a mobile terminal. The file transmission method comprises the following steps that (1) WIFI hot spots are self-created by a mobile terminal transmitting side, and names of the hot spots are generated to wait for a connecting request; (2) surrounding WIFI hot spots are looked for by a mobile terminal receiving side, the connecting request is transmitted to the target WIFI hot spots after the target WIFI hot spots are found, and an independent service socket message center is started after the mobile terminal transmitting side receives the connecting request; (3) a file receiving server is started by the mobile terminal receiving side; (4) a file transmitting task is started by the mobile terminal transmitting side, files are transmitted to the mobile terminal receiving side, and then file transmission is completed. The file transmission method has the advantages that participation and departure of users can be instantly detected, data transmission is completely isolated from service transmission, under the limitation of WIFI physical permission, transmission of service commands among terminals can not be affected by file transmission tasks, and data transmission processing pressure is effectively diffused.

Description

technical field [0001] The invention relates to the technical field of wifi data transmission of a mobile terminal, in particular to a mobile terminal using an android operating system. Background technique [0002] Existing mobile terminal devices allow self-built wifi hotspots, and also allow to connect and join wifi hotspots. The android SDK also opens up the api for mobile terminal wifi including ap operations, and opens up the reading of pictures, music, and videos on mobile terminals. Write operation, program read and write operation and installation, address book, text message and network socket read and write operation. This makes it possible to transfer files between mobile terminals. [0003] At present, the method of transferring files between mobile terminals through WIFI is realized by means of socket multicast or udp message packet. Can rely on heartbeat timeout to detect disconnected users, the detection of offline users lags behind, and cannot detect users ...
