Abstract: The present disclosure discloses an instant messaging method, terminal, server and system. The method includes: a first instant messaging terminal transmitting a transfer request to a second instant messaging terminal, both terminals logged into the same instant messaging account; the second instant messaging terminal responding to the transfer request, transmitting a reply command accepting the transfer; after receiving the reply command, the first instant messaging terminal obtaining information of the current instant messaging session and transmitting the information to the second instant messaging terminal; the second instant messaging terminal setting an instant messaging session based on the received information. The present disclosure can facilitate effective transfer of an instant messaging session, thus allowing a user to easily continue the previous instant messaging session after switching to a different terminal.

Abstract: Methods, terminals, servers, and systems for sharing data are disclosed. The data-sharing method can include: a first instant messaging terminal transmitting a data-sharing request to a second instant messaging terminal; the second instant messaging terminal responding to the data-sharing request by transmitting a reply permitting data sharing to the first instant messaging terminal, the reply including an identifier (ID) collection of the shareable data resources; the first instant messaging terminal transmitting a data-reading request to the second instant messaging terminal, the data-reading request including at least one data resource ID; the second instant messaging terminal transmitting a data resource corresponding to the data resource ID in the data-reading request to the first instant messaging terminal. This allows simple and fast data-sharing among multiple terminals.
