Embodiment
Embodiment of the present invention provides a kind of method, Apparatus and system of point-to-point file transfer, specifically is in point-to-point document transmission process, when receiving side terminal is temporarily abandoned receiving file, will remain file and be sent to server and carry out buffer memory; And under the situation of receiving side terminal login next time or conditions permit, continue again to download the residue file from server, thereby improved the efficient of point-to-point file transfer, promote user experience, and reduced the network bandwidth resources waste.
For better describing the embodiment of the invention, now in conjunction with the accompanying drawings specific embodiments of the invention are described, be illustrated in figure 1 as the schematic flow sheet of the receiving side terminal side of point-to-point document transmission method that the embodiment of the invention provides, described method comprises:
Step 11: receiving side terminal interrupts receiving file in the process that receives sending side terminal transmission file, and asks to the storage of server transmission temporary file, is sent to described server buffer to notify described sending side terminal will remain file;
In this step, when receiving side terminal receives the file that sending side terminal sent, if described receiving side terminal interrupts receiving file, then receiving side terminal notice sending side terminal will remain file and forward server buffer to, specifically:
Receiving side terminal sends temporary file storage request to server, will remain file by this server notification sending side terminal and be sent to described server and carry out buffer memory.
In addition, after sending side terminal and server were set up the file transfer passage, described receiving side terminal also can receive and preserve the file transfer breakpoint information that described sending side terminal sends.
Step 12:, download the residue file of buffer memory from described server when described receiving side terminal satisfies when receiving file condition once more.
In this step, need whether satisfy receiving file condition once more and determine receiving side terminal, when definite receiving side terminal satisfies when receiving file condition once more, this receiving side terminal just can remain file from described server download.
In the specific implementation process, when described receiving side terminal login authentication is passed through, and when this receiving side terminal receives the temporary file announcement information of server transmission, determine the satisfied file condition that receives once more of receiving side terminal, then described receiving side terminal and described server are set up the file transfer passage, continue to receive the residue file that is buffered in described server.
The foregoing description is the implementation process of receiving side terminal side in the point-to-point document transmission method, just can improve the efficient of point-to-point file transfer by this method, has promoted user experience, and has reduced the network bandwidth resources waste.
Be described in detail at the specific implementation process of sending side terminal side, server side in the point-to-point document transmission method more below:
The embodiment of the invention also provides a kind of method of point-to-point file transfer, is specially the implementation process of sending side terminal side, and as the schematic flow sheet of Fig. 2 for the sending side terminal side of point-to-point document transmission method that the embodiment of the invention provides, described method comprises:

AAS (Authorization Authentication Service) server, the authentication of landing that is used for receiving side terminal, after receiving side terminal lands authentication and passes through, proactive notification FTSS server, the FTSS server judges further whether receiving side terminal has temporary file to wait to receive, whether the residue file of buffer memory is promptly arranged, if exist then this receiving side terminal of proactive notification obtains the residue file of described buffer memory.
Above-mentioned FTSS server and AAS server can be distinguished independent existence, also can be integrated into a server function corresponding is provided.
Be illustrated in figure 5 as the embodiment of the invention and lift Signalling exchange schematic diagram in the instantiation, comprise among the figure:
1, sending side terminal A and receiving side terminal B carry out file transfer, and file transfer is numbered FileID;
2, receiving side terminal B need leave, the file of having to stop to receive, at this moment receiving side terminal B initiates temporary file storage request (Temp_StoreFile_request.req) to the FTSS server, and FileID and Sender ID are carried in described temporary file storage request;
3, the FTSS server is initiated the cache file notice according to described Sender ID to sending side terminal A, and described cache file notice is carried FileID and Receiver ID;
4, sending side terminal A preserves the file transfer breakpoint information, stops to continue transfer files to receiving side terminal B, initiates temporary file transmission request (Temp_FileTransfer_request.req) to the FTSS server subsequently;
5, the FTSS server returns temporary file transmission response (Temp_FileTransfer_request.res);
6, sending side terminal A and FTSS server are set up the file transfer passage, and begin to remain file transfer from breakpoint, will remain file transfer and give the FTSS server buffer;
7, sending side terminal A sends the file transfer breakpoint information to receiving side terminal B after setting up the file transfer passage with the FTSS server, and the file transfer of end and receiving side terminal B, and this receiving side terminal B receives the file transfer breakpoint information and preserves;
8, receiving side terminal B reaches the standard grade once more, and the AAS server gets access to after the online information of receiving side terminal B, and B logins authentication to receiving side terminal, and after the login authentication is passed through, notice FTSS server receiving side terminal B login;
9, the FTSS server judges further whether receiving side terminal B has temporary file to need transmission, if judge have, then determines the satisfied file condition that receives once more of receiving side terminal B, and sends the temporary file announcement information to receiving side terminal B;
10, receiving side terminal B initiates to receive temporary file transmission request Temp_StoreFile_receive.req to the FTSS server;
11, the FTSS server returns temporary file transmission response (Temp_StoreFile_receive.res) to receiving side terminal B.
12, FTSS server and receiving side terminal B set up the temporary file transmission channel, and receiving side terminal B begins to continue from the FTSS server residue file of reception buffer memory based on the file transfer breakpoint information.
After the residue file transfer was finished, the FTSS server can be deleted the temporary file of buffer memory, and receiving side terminal B can viewing files information.
