Abstract

A method for synchronizing messages between multiple terminals includes: receiving a message state change notification carrying a message state and a message identifier from a first terminal of a user; and sending a message state change notification to the second terminal of the user, according to the message state change notification. A method for synchronizing storage layouts between multiple terminals includes: receiving a storage layout synchronization request carrying a storage directory and/or storage data from a first terminal; sending the storage layout synchronization request to other terminal correlated with the first terminal, so that the other related terminals update the messages or synchronize the media data and/or storage structures. The invention also discloses a server and a terminal for synchronizing messages between multiple terminals. Through the present invention, messages, message states, storage data, and storage structures can be synchronized between multiple terminals.

Claims

1. A method for synchronizing between multiple terminals, characterized by comprising:

receiving, by a server, a message for indicating synchronizing requirement from a first terminal; and

sending, by the server, the message for indicating synchronizing requirement to a second terminal correlated with the first terminal.

2. The method of claim 1, wherein the message for indicating synchronizing requirement is a message state change notification carrying a message state and a message identifier.

3. The method of claim 1, wherein the message for indicating synchronizing requirement is a message update notification carrying update information.

4. The method of claim 1, wherein the message for indicating synchronizing requirement is a storage layout synchronization request carrying a storage directory and/or storage data.

5. The method of claim 1, wherein sending by the server the message for indicating synchronizing requirement to a second terminal correlated with the first terminal further comprises:

if determining that the second terminal correlated with the first terminal is online, sending the message for indicating synchronizing requirement to the second terminal correlated with the first terminal;

if determining that the second terminal correlated with the first terminal is offline, storing the message for indicating synchronizing requirement and sending the message for indicating synchronizing requirement to the second terminal correlated with the first terminal after the second terminal goes online.

6. The method of claim 1, wherein the message for indicating synchronizing requirement is received by the server through the APPEND command of the SIP PUBLISH, SIP MESSAGE, MSRP SEND, MSRP REPORT, or IMAP protocol, or the STORE command of the IMAP protocol.

7. The method of claim 1, wherein the message for indicating synchronizing requirement is sent by the server to the second terminal correlated with the first terminal through SIP NOTIFY, SIP MESSAGE, MSRP SEND, MSRP REPORT, or IMAP FETCH.

8. A server, characterized by comprising:

a receiving module, adapted to receive a message for indicating a synchronizing requirement from a first terminal; and

a sending module, adapted to send the message for indicating the synchronizing requirement to a second terminal correlated with the first terminal.

9. The server of claim 8, wherein the server further comprises:

an identifier obtaining module, adapted to obtain identifier of the second terminal correlated with the first terminal, so that the sending module sends the message for indicating the synchronizing requirement according to the identifier of the second terminal.

10. The server of claim 8, wherein the server further comprises:

a judging module, adapted to judge whether the second terminal is online;

wherein if the judging module determines that the second terminal is online, the sending module sends the message for indicating the synchronizing requirement to the second terminal;

if the judging module determines that the second terminal is offline, the sending module sends the message for indicating the synchronizing requirement to the second terminal correlated with the first terminal after the second terminal goes online.

11. The server of claim 8, wherein the message for indicating the synchronizing requirement is one of (1) a message state change notification carrying a message state and a message identifier;

(2) a message update notification carrying update information; and

(3) a storage layout synchronization request carrying one or more of a storage directory and storage data.

12. A terminal, comprising:

a data processing module, adapted to implement data processing;

a sending module, adapted to send a message for indicating a synchronizing requirement to a server, after the message processing module implements the data processing.

13. The terminal of claim 12 further comprising:

an identifier obtaining module, adapted to obtain identifier of another terminal correlated with the terminal, so that the sending module establishes a transmission path with the another terminal, according to the identifier of the another terminal, and sends the message for indicating the synchronizing requirement through the transmission path.

14. The terminal of claim 12, wherein the data processing comprises one or more of:

(1) update a message;

(2) change a message state;

(3) one of creating, deleting, or renaming a storage directory; and

(4) one of storing, updating, deleting, copying, or moving storage data.
