Abstract

A terminal, server and method for storing and selectively retrieving SIP-based messages, are discussed. According to an embodiment, the present invention provides a method for controlling a SIP-based message by a control server, which includes receiving a SIP-based message; determining a manner in which the SIP-based message is to be processed based on user preference information; transmitting the SIP-based message and indication information to a storage server based on the determination result, the indication information indicating if the SIP-based message is to be sent back with link information, the link information including a reference to the SIP-based message; receiving a part of the SIP-based message and the link information from the storage server; and transmitting the part of the SIP-based message and the link information to a terminal, whereby the SIP-based message can be selectively retrieved.

Claims

1. A method for controlling a Session Initiation Protocol (SIP)-based message at a storage server, the method comprising:

receiving the SIP-based message including indication information from a control server, wherein the indication information indicates a manner in which the SIP-based message is to be handled by the storage server;

transmitting a first part of the SIP-based message and link information to the control server when the indication information indicates that the SIP-based message is to be sent back to the control server;

transmitting a notification message from the storage server to a terminal when the indication information indicates that the storage server notifies the terminal regarding the SIP-based message; and

performing a synchronization with the terminal when the terminal initiates the synchronization,

wherein the synchronization includes;

receiving a get command including a URI (uniform resource indicator) from the terminal,

when the URI is represented by a global unique identifier (GUID) of the SIP-based message, a delimiting character, and a content identifier, transmitting a put command including a second part of the SIP-based message indicated by the content identifier to the terminal, and

when the URI is represented by the global unique identifier (GUID) of the SIP-based message, transmitting a put command including the SIP-based message to the terminal.

2. The method of claim 1, wherein the SIP-based message is a Converged IP Messaging (CPM) message.

3. The method of claim 1, wherein the link information includes the global unique identifier (GUID) of the SIP-based message.

4. The method of claim 1, wherein the link information includes the content identifier for identifying the second part of the SIP-based message.

5. The method of claim 1, wherein the SIP-based message comprises a plurality of parts, and the link information includes a plurality of content identifiers respectively assigned to the plurality of parts of the SIP-based message for selectively retrieving one or more parts of the SIP-based message.

6. A method for controlling a Session Initiation Protocol (SIP)-based message at a control server, the method comprising:

receiving the SIP-based message;

transmitting the SIP-based message including indication information to a storage server based on user preference information, wherein the indication information indicates a manner in which the SIP-based message is to be handled by the storage server;

when the indication information indicates that the SIP-based message is to be sent back to the control server,

receiving a first part of the SIP-based message and link information from the storage server; and

transmitting the first part of the SIP-based message and the link information to a terminal; and

performing a synchronization with the terminal when the terminal initiates the synchronization,

wherein the synchronization includes;

receiving a get command including a URI (uniform resource indicator) from the terminal,

when the URI is represented by a global unique identifier (GUID) of the SIP-based message, a delimiting character, and a content identifier, transmitting a put command including a second part of the SIP-based message indicated by the content identifier to the terminal, and

when the URI is represented by the global unique identifier (GUID) of the SIP-based message, transmitting a put command including the SIP-based message to the terminal.

7. The method of claim 6, wherein the SIP-based message is a Converged IP Messaging (CPM) message.

8. The method of claim 6, wherein the link information includes the global unique identifier (GUID) of the SIP-based message.

9. The method of claim 6, wherein the link information includes the content identifier for identifying the second part of the SIP-based message.

10. The method of claim 6, wherein the SIP-based message comprises a plurality of parts, and the link information includes a plurality of content identifiers respectively assigned to the plurality of parts of the SIP-based message for selectively retrieving one or more parts of the SIP-based message.
