Abstract

Provided is a system for delivering an instant message in which instant messaging systems of different types interwork. The system includes a transmitter mobile communication terminal and an interworking server. The transmitter mobile communication terminal connected to a first instant messaging system transmits a request for an instant message receipt report to a receiver mobile communication terminal connected to a second instant messaging system. The interworking server converts the delivery format of the instant message into another suitable for the second instant messaging system and transmits the instant message to the receiver mobile commnunication terminal. The interworking server also converts the delivery format of the instant message receipt report generated accorrding to the receipt result of the instant message by the receiver mobile communication terminal after completion of the delivery of the instant message to the receiver mobile communication terminal into another suitable for the delivery format of the first instant messaging system to which the transmitter mobile communication terminal is connected, and transmits the instant message receipt report to the transmitter mobile communication terminal.

Claims

1. An instant messaging method in a Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIP/SIMPLE) instant messaging system, the instant messaging method comprising the steps of:

a sender mobile communication terminal generating an instant message delivery report request in the delivery of an instant message;

if a delay in the delivery of the instant message occurs, waiting without sending an instant message delivery report until the receipt status of the instant message by a recipient mobile communication terminal is dete rmined; and

if the determination is made, generating the instant message delivery report including information about the receipt status of the instant message and sending the instant message delivery report to the sender mobile communication terminal.

2. The instant messaging method of claim 1, wherein the delay occurs when the recipient mobile communication terminal cannot receive the instant message at that time, i.e., is not reachable.

3. The instant messaging method of claim 2, wherein the delay is recognized by the generation of a 202 Accepted response code with respect to the instant message.

4. The instant messaging method of claim 3, wherein the instant message delivery report further includes information about a reason for a failure in the receipt of the instant message.

5. The instant messaging method of claim 4, wherein the instant message delivery report request and the instant message delivery report are sent through a “

Message”

primitive.

6. An instant messaging method in an instant messaging system where two instant messaging systems of different types interwork, the instant messaging method comprising the steps of:

a sender mobile communication terminal connected to one of the tnvo instant messaging systems generating an instant message delivery report request to a recipient mobile communication terminal connected to the other instant messaging system;

converting the delivery format of an instant message into another suitable for the other instant messaging system and delivering the instant message to the recipient mobile communication terminal;

upon completion of the delivery of the instant message to the recipient mobile communication terminal, generating an instant message delivery report including information about the receipt status of the instant message by the recipient mobile communication terminal; and

converting the delivery format of the instant message delivery report to another suitable for the system to which the sender mobile communication terminal is connected and sending the instant message delivery report to the sender mobile communication terminal.

7. The instant messaging method of claim 6, wherein the instant messaging systems are an Interpersonal Messaging Service (IMPS) system and a Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIP/SIMPLE) system.

8. The instant messaging method of claim 6, wherein the instant message delivery report includes any one of Successfully received, Receipt rejected, Validity expires, and Delivery failure.

9. A Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIP/SIMPLE) instant messaging system comprising:

a sender mobile communication terminal for generating an instant message delivery report request in the delivery of an instant message; and

an SIP/SIMPLE server for waiting without sending an instant message delivery report until the receipt status of the instant message by a recipient mobile communication terminal is determined, if a delay in the delivery of the instant message occurs, and if the determination is made, generating the instant message delivery report including information about the receipt status of the instant message and sending the instant message delivery report to the sender mobile communication terminal.

10. The SIP/SIMPLE instant messaging system of claim 9, wherein the SIP/SIMPLE server recognizes that the delay occurs if the recipient mobile communication terminal cannot receive the instant message at that time, i.e., is not reachable.

11. The SIP/SIMPLE instant messaging system of claim 10, wherein the SIP/SIMPLE server recognizes that the delay occurs if a202 Accepted response code is generated with respect to the instant message.

12. The SIP/SIMPLE instant messaging system of claim 11, wherein the instant message delivery report further includes information about a reason for a failure in the receipt of the instant message.

13. The SIP/SIMPLE instant messaging system of claim 12, wherein the instant message delivery report request and the instant message delivery report are sent through a “

Message”

primitive.

14. An instant messaging system in which instant messaging systems of different types interwork, the instant messaging system comprising:

a sender mobile communication terminal connected to one of the instant messaging systems for generating an instant message delivery report request to a recipient mobile communication terminal connected to the other instant messaging system; and

an interworking server for converting the delivery format of an instant message into another suitable for the other instant messaging system, delivering the instant message to the recipient mobile communication terminal, generating an instant message delivery report including information about the receipt status of the instant message by the recipient mobile communication terminal upon completion of the delivery of the instant message to the recipient mobile communication terminal, converting the delivery format of the instant message delivery report to another suitable for the system to which the sender mobile communication terminal is connected, and sending the instant message delivery report to the sender mobile communication terminal.

15. The instant messaging system of claim 14, wherein the instant messaging systems are an Interpersonal Messaging Service (IMPS) system and a Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIP/SIMPLE) system.

16. The instant messaging system of claim 15, wherein the instant message delivery report includes any one of Successfully received, Receipt rejected, Validity expires, and Delivery failure.

17. An instant messaging system in which an Interpersonal Messaging Service (IMPS) system and a Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIP/SIMPLE) system interwork, the instant messaging system comprising:

an IMPS server for delivering an instant message according to IMPS;

an SIP/SIMPLE server for delivering the instant message according to SIP/SIMPLE;

a first mobile communication terminal included in a service coverage of the IMPS server;

a second mobile communication terminal included in a service coverage of the SIP/SIMPLE server; and

an interworking server for, if one of the mobile communication terminals generates an instant message delivery report request to the other mobile communication terminal in the delivery of the instant message, converting the delivery format of the instant message received from a server of a sender mobile communication terminal into another suitable for a system including a recipient mobile communication terminal, delivering the instant message to a server of the recipient mobile communication terminal, collecting an instant message delivery report including information about the receipt status of the instant message by the recipient mobile communication terminal upon completion of the delivery of the instant message to the recipient mobile communication terminal, converting the delivery format of the instant message delivery report to another suitable for a system including the sender mobile communication terminal, and sending the instant message delivery report to the server of the sender mobile communication terminal.
