Abstract

A method is provided for receiving a session history by a Controlling Function (CF) in a communication system. The method includes sending, by a CF in a first domain, a first message requesting a session history to a Conversation Server (CS) in the first domain; receiving, from the CS in the first domain, a second message including access information to a CS in a second domain, which has a session history, when the CS in the first domain has no session history; sending a third message requesting a session history to the CS in the second domain, which has the session history, based on the access information; and receiving a fourth message including the session history from the CS in the second domain.

Claims

1. A method for receiving a session history by a controlling function (CF) in a communication system, the method comprising the steps of:

sending, by a CF in a first domain, a first message to a conversation server (CS) in the first domain, the first message requesting the session history;

if the CS in the first domain is not managing the session history, receiving, by the CF, a second message from the CS in the first domain, the second message specifying an entity managing the session history;

receiving, by the CF, via the CS in the first domain from a CS in a second domain, a third message including access information for the CS in a second domain, which has the session history;

sending, by the CF, a fourth message to the CS in the second domain, which has the session history, based on the access information, the fourth message requesting the session history; and

receiving, by the CF, a fifth message from the CS in the second domain, the fifth message including the session history.

2. The method of claim 1, wherein each of the first message and the fourth message includes a destination address of the CS in the first domain or the CS in the second domain, a content-type for requesting session history-related information, and information about a session identifier.

3. The method of claim 1, wherein each of the third message and the fifth message includes an address of the CS in the first domain or the CS in the second domain, a content-type indicating that the message is a response to a session history request, information about a one-to-one session identifier, information about a group session identifier, and information about a server managing the session history.

4. A method for transmitting and receiving a group session history in a communication system in which a group session is created between at least two client terminals, the method comprising the steps of:

receiving, by a conversation server (CS) in a first domain, a first message from a client terminal in the first domain, the first message requesting the group session history;

if the CS in the first domain is not managing the group session history, sending, by the CS, a second message to a controlling function (CF) in the first domain, the second message specifying an entity managing the group session history;

receiving, by the CS, a third message including access information for a storage area in which the group session history is stored, from a CF in a second domain;

reading, by the CS, the group session history from the storage area based on the access information; and

transmitting, by the CS, the read group session history to the client terminal.

5. The method of claim 4, wherein a protocol used to read the group session history includes an internet message access protocol (IMAP).

6. The method of claim 4, wherein a protocol used to transmit the group session history to the client terminal in the first domain includes a message session relay protocol (MSRP).

7. The method of claim 4, wherein each of the first message and the third message includes a session initiation protocol (SIP)-based MESSAGE message.

8. The method of claim 4, further comprising sending, by the CS, a fourth message to the CF in the second domain, the fourth message requesting the group session history.

9. The method of claim 8, wherein each of the first message and the fourth message includes a session initiation protocol (SIP)-based MESSAGE message.

10. The method of claim 8, wherein the CF in the second domain and the CS in the first domain transmit the group session history using a message session relay protocol (MSRP)-protocol message.

11. The method of claim 4, further comprising notifying, by the client terminal in the first domain, the CS in the first domain of its acquisition of the group session history.

12. A method for transmitting and receiving a group session history in a communication system in which a group session is created between at least two client terminals, the method comprising the steps of:

receiving, by a conversation server (CS) in a first domain, a first message from a client terminal in the first domain, the first message requesting the group session history;

if the CS in the first domain is not managing the group session history, sending, by the CS in the first domain, a second message to a controlling function (CF) in the first domain, the second message specifying an entity managing the group session history;

sending, by the CS in the first domain, a third message to a CF in a second domain, the third message requesting the group session history;

receiving, by the CS in the first domain, the group session history from the CF in the second domain, wherein the CF in the second domain acquires the group session history from a storage area in which the group session history is stored; and

transmitting, by the CS in the first domain, the group session history to the client terminal in the first domain.

13. The method of claim 12, wherein each of the first messages and the third message includes a session initiation protocol (SIP)-based MESSAGE message.

14. The method of claim 12, wherein the CF in the second domain uses an internet message access protocol (IMAP)-based message to acquire the group session history from the storage area.

15. The method of claim 12, wherein the CS in the first domain uses a message session relay protocol (MSRP)-based message to transmit the group session history.
