Abstract

A method and system for file transfer, an instant messaging terminal, and a computer storage medium are described, so as to solve the problem that in case of a poor network environment, too much manual intervention is required when file transfer through an existing instant messaging software encounters a network connection interruption, leading to a low transfer efficiency and poor user. With the present disclosure, an instant messaging terminal is provided with an option of automatic retransfer upon disconnection, an option of automatic reception upon disconnection, and an option of automatic offline-file forwarding upon disconnection, such that when transfer of a file is interrupted, an instant messaging system can automatically retransfer (or resume the interrupted transfer of) the file, thus enhancing efficiency in file transfer.

Claims11

Dependent claims

A method for file transfer, the method being applied to an instant messaging system, and comprising:

configuring an option of automatic retransfer upon disconnection for a sender;
when transfer of a file is interrupted and determined that the sender is configured with the option of automatic retransfer upon disconnection, monitoring, by the sender, in real time whether the network connection is back to normal, and sending automatically, by the sender, an online file-retransfer or online resuming-file-transfer request to a receiver after detecting that the network connection is back to normal;
configuring an option of automatic reception upon disconnection for the receiver;
when transfer of a file is interrupted and determined that the receiver is configured with the option of automatic reception upon disconnection, responding to automatically, by the receiver, a file-retransfer or resuming-file-transfer request from the sender and sending the sender a response to confirm receiving;
retransferring, by the sender, the file or resuming the transfer of the file after receiving a response to confirm receiving from the receiver;
and
when the sender is configured with an option of automatic offline-file forwarding upon disconnection, sending, by the sender, the file to a server for cache to allow the receiver receive the file or resume the interrupted transfer of the file from the server after the receiver goes on line in case that no response to confirm receiving by the receiver is received within a set period.

4 more elements

An instant messaging terminal, comprising:

a memory storing instructions;
and
a hardware processor executing the instructions to implement a first configuring module, an automatic retransferring module, a second configuring module and an automatic receiving module, wherein
the first configuring module is arranged to configure or cancel an option of automatic retransfer upon disconnection;
the automatic retransferring module is arranged to, when the option of automatic retransfer upon disconnection is configured and when transfer of a file is interrupted, monitor in real time whether the network connection is back to normal, send automatically an online file-retransfer or online resuming-file-transfer request to a receiver after detecting that the network connection is back to normal, and retransfer the file on line or resume on line the interrupted transfer of the file to the receiver after a response to confirm receiving by the receiver is received;
wherein the first configuring module is further arranged to configure or cancel an option of automatic offline-file forwarding upon disconnection;
the automatic retransferring module is further arranged to, when the option of automatic offline-file forwarding upon disconnection is configured, send the file to a server for cache to allow the receiver receive the file or resume the interrupted transfer of the file from the server after the receiver goes on line in case that no response to confirm receiving by the receiver is received within a set period;
the second configuring module is arranged to configure or cancel an option of automatic reception upon disconnection;
and
the automatic receiving module is arranged to, when the option of automatic reception upon disconnection is configured and when transfer of a file is interrupted, respond to automatically a file-retransfer or resuming-file-transfer request sent from a sender after detecting that the network connection is back to normal by sending the sender a response to confirm receiving, and receive the whole file again, or resume reception of the interrupted file;
and in case that no response to confirm receiving is sent to the sender within the set period, trigger the sender configuring with an option of automatic offline-file forwarding upon disconnection to send the file to the server for cache to allow the receiver receive the file or resume the interrupted transfer of the file from the server after the receiver goes on line.

8 more elements

A system for file transfer, comprising a first instant messaging terminal which serves as a file sender, a server, and a second instant messaging terminal which serves as a file receiver,

the first instant messaging terminal comprising:
a memory storing instructions;
and
a hardware processor executing the instructions to implement a first configuring module and an automatic retransferring module, wherein
the first configuring module is arranged to configure or cancel an option of automatic retransfer upon disconnection;
and
the automatic retransferring module is arranged to, when the option of automatic retransfer upon disconnection is configured and when transfer of a file is interrupted, monitor in real time whether the network connection is back to normal, send automatically an online file-retransfer or online resuming-file-transfer request to a receiver after detecting that the network connection is back to normal, and retransfer the file on line or resume on line the interrupted transfer of the file to the receiver after a response to confirm receiving by the receiver is received,
wherein the first configuring module is further arranged to configure or cancel an option of automatic offline-file forwarding upon disconnection;
the automatic retransferring module is further arranged to, when the option of automatic offline-file forwarding upon disconnection is configured, send the file to the server for cache to allow the receiver receive the file or resume the interrupted transfer of the file from the server after the receiver goes on line in case that no response to confirm receiving by the receiver is received within a set period;
the second instant messaging terminal comprising:
a memory storing instructions;
and
a hardware processor executing the instructions to implement a second configuring module and an automatic receiving module, wherein
the second configuring module is arranged to configure or cancel an option of automatic reception upon disconnection;
and
the automatic receiving module is arranged to, when the option of automatic reception upon disconnection is configured and when transfer of a file is interrupted due to the network connection interruption, respond to automatically a file-retransfer or resuming-file-transfer request sent from the sender after detecting that the network connection is back to normal by sending the sender a response to confirm receiving, land receive the whole file again, or resume reception of the interrupted file;
and in case that no response to confirm receiving is sent to the sender within the set period, trigger the sender configuring with the option of automatic offline-file forwarding upon disconnection to send the file to the server for cache to allow the receiver receive the file or resume the interrupted transfer of the file from the server after the receiver goes on line.
