Abstract
A method for performing session merging between PoC sessions under the environment of multiple PoC sessions is provided. A merging PoC client sends a request for the session merging with a merged session to a PoC server managing a merging session to which the PoC client belongs. The PoC server managing the merging session sends a session merge request to a PoC server managing the merged session. Negotiation of a CF (Controlling PoC Function) for managing a session to be merged is performed between the PoC server of the merging session and the PoC server of the merged session. When an entire CF of the session to be merged is selected as the negotiation between the PoC servers is completed, the PoC server of the merged session sends an UPDATE message of modified media parameters to a PoC client of the merged session. The PoC server of the merging session sends, to a PoC client of the merging session, a NOTIFY message of a merge request notifying that the PoC server of the merging session is selected as the entire CF.

25. A method for merging sessions in clients, comprising:
-
generating, at a first client, a message including group identification information of the first client and sending the message to a second client connected to a second sewer via a first server connected to the first client; generating, at the second client, a session merge request message using group identification information included in a message sent from the second server, and sending the session merge request message to the first sewer connected to the second client; and receiving, at the second client, a message on session merging from the second server connected to the second client, and sending and receiving a message by merging sessions with the first client through the second server based on the received message.

26. A method for merging sessions in a server, comprising:
-
receiving, at a first server subjected to session merging, a message from at least one client belonging to the first server, the message including group identification information of the client; sending, at the first server, the received message to a second server on which session merging is to be performed; sending, at the second server, the message received from the first server to a client connected to the second server; receiving, at the second server, a session merge request message from the client connected to the second server; sending, at the second server, the session merge request message to the first server using the group identification information of the client belonging to the first server; and proceeding communication through the client belonging to the first server and the second server when an approval message for a Controlling PoC Function (CF) is received from the first server in response to the session merge request message. - View Dependent Claims (27)
