Abstract
A method is described for transferring a converged IP messaging (CPM) service based message using a server. The server transmits one or more messages via a one-to-one session established between a first terminal of a first user and a second terminal of a second user. The server receives a first session initiation protocol (SIP) invite message for extending the one-to-one session to a group session from the first terminal of the first user. The server extracts and locally stores various headers and IDs from the received first SIP invite message, and at least part of session description protocol (SDP) attributes with media streams from the received first SIP invite message if the first SIP invite message includes SDP content describing the media streams. The server transmits a second SIP invite message to the second terminal of the second user, and receives a termination message for terminating the one-to-one session.
