Abstract

A session integration method is provided for integrating a first session between a first entity and a third entity and a second session between a second entity and the third entity in a session-based service environment. The first entity receives a REFER message including dialog information from the second entity, and sends a response message to the received REFER message to the second entity. When header information included in the received REFER message indicates an INVITE message and the dialog information is related to the first entity, the first entity generates a Re-INVITE message and sends the generated Re-INVITE message to an address of a target which is subject to session integration. The address is included in the header information and corresponds to the third entity. The first entity updates the first session into an integrated session with the third entity.

Claims

1. A session integration method for integrating a first session between a first entity and a third entity and a second session between a second entity and the third entity in a session-based service environment, comprising the steps of:

receiving, by the first entity, a REFER message including dialog information from the second entity;

sending, by the first entity, a response message to the received REFER message to the second entity;

generating, by the first entity, a Re-INVITE message when header information included in the received REFER message indicates an INVITE message and the dialog information is related to the first entity;

sending, by the first entity, the generated Re-INVITE message to an address of a target which is subject to session integration, wherein the address is included in the header information and corresponds to the third entity; and

updating, by the first entity, the first session into an integrated session with the third entity.

2. The session integration method of claim 1, wherein the header information comprises a call-id parameter, a from-tag parameter and a to-tag parameter as the dialog information.

3. The session integration method of claim 1, wherein the header information comprises Identifier (ID) values of dialog elements in a dialog package document that includes a call-id parameter, a from-tag parameter and a to-tag parameter as the dialog information.

4. The session integration method of claim 3, further comprising:

sending, by the first entity, a SUBSCRIBE message requesting the dialog package document to a dialog management server before sending the Re-INVITE message;

receiving, by the first entity, a NOTIFY message including the dialog package document from the dialog management server; and

acquiring, by the first entity, the dialog information from the dialog package document in the NOTIFY message.

5. The session integration method of claim 1, wherein the second session is released when the third entity sends a BYE message for closing a dialog indicated by the header information to the second entity and receives a response message to the BYE message from the second entity.

6. The session integration method of claim 5, wherein the release of the second session is accomplished when the third entity sends a NOTIFY message indicating completion of the session integration to the second entity and receives a response message to the NOTIFY message from the second entity, before the sending of the BYE message to the second entity.

7. A session integration apparatus of a first entity in a system for integrating a first session between the first entity and a third entity and a second session between a second entity and the third entity in a session-based service environment, comprising:

means for receiving a REFER message including dialog information and sending a response message to the received REFER message to the second entity; and

means for generating a Re-INVITE message and sending the generated Re-INVITE message to a target address included in header information of the REFER message, when the header information indicates an INVITE message and the dialog information included in the header information is related to the first entity.

8. The session integration apparatus of claim 7, wherein the header information comprises a call-id parameter, a from-tag parameter and a to-tag parameter as the dialog information.

9. The session integration apparatus of claim 7, wherein the header information comprises Identifier (ID) values of dialog elements in a dialog package document that includes a call-id parameter, a from-tag parameter and a to-tag parameter as the dialog information.

10. The session integration apparatus of claim 9, further comprising means for sending a SUBSCRIBE message requesting the dialog package document to a dialog management server before sending the Re-INVITE message, receiving a NOTIFY message including the dialog package document from the dialog management server, and acquiring the dialog information from the dialog package document.

11. The session integration apparatus of claim 7, wherein the second session is released when the third entity sends a BYE message for closing a dialog indicated by the header information to the second entity and receives a response message to the BYE message from the second entity.

12. The session integration apparatus of claim 11, wherein the release of the second session is accomplished when the third entity sends a NOTIFY message indicating completion of the session integration to the second entity and receives a response message to the NOTIFY message from the second entity, before the sending of the BYE message to the second entity.

13. A session integration method for integrating a first session between a first entity and a third entity and a second session between a second entity and the third entity in a session-based service environment, comprising the steps of:

sending, by the second entity, a REFER message including dialog information to the first entity through the third entity;

receiving, by the second entity, a response message to the REFER message from the first entity through the third entity;

receiving, by the second entity, BYE message for close the dialog from the third entity when the second session is integrated into the first session; and

sending, by the second entity, a response message to BYE message to the third entity for release of the second session.

14. The session integration method of claim 13, wherein the release of the second session is accomplished when the second entity receives a NOTIFY message indicating completion of the session integration from the third entity and sends a response message to the NOTIFY message to the third entity, before the receiving of the BYE message from the third entity.

15. The session integration method of claim 13, wherein the REFER message includes header information indicating an INVITE message and the dialog information is related to the first entity.

16. The session integration method of claim 13, wherein the header information comprises a call-id parameter, a from-tag parameter and a to-tag parameter as the dialog information.

17. The session integration method of claim 13, wherein the header information comprises Identifier (ID) values of dialog elements in a dialog package document that includes a call-id parameter, a from-tag parameter and a to-tag parameter as the dialog information.

18. The session integration method of claim 15, wherein integrating the second session into the first session by sending a Re-INVITE message from the first entity to the third entity and sending a response message to the Re-INVITE message from the third entity to the first entity when header information included in the REFER message indicates an INVITE message and the dialog information is related to the first entity.

19. A session integration apparatus of a second entity in a system for integrating a first session between a first entity and a third entity and the second session between a second entity and the third entity in a session-based service environment, comprising:

means for sending a REFER message including dialog information to the first entity through the third entity and sending a response message to BYE message to the third entity for release of the second session; and

means for receiving a response message to the REFER message from the first entity through the third entity and receiving BYE message for close the dialog from the third entity when the second session is integrated into the first session.

20. The session integration apparatus of claim 19, wherein the REFER message includes header information indicating an INVITE message and the dialog information is related to the first entity.
