Abstract

A method for transferring a session between clients is provided when one user uses multiple clients on a service (for example, Push to talk over Cellular (PoC), Instant Messaging (IM), Converged-Internet Protocol (IP) Messaging (CPM)) providing system implemented through a Session Initiation Protocol (SIP) / IP core network. A session transfer method is provided when the user needs to transfer a session to another client while the session is performed through one client. A temporary storing technique is used in which a conversation server or client as one of elements of a seamless CPM system for providing a seamless user environment temporarily stores data transmitted from another user during session transfer.

Description

technical field [0001] The present invention generally relates to a service provision method and system implemented through a Session Initiation Protocol / Internet Protocol (SIP / IP) core network, and in particular, to a method for transferring (transfer) between multiple clients. ) method and system for conversation. Background technique [0002] In the existing mobile environment, terminals send occasional messages such as Short Message Service (SMS) and Multimedia Message Service (MMS). On the other hand, users may need to easily exchange message services for conversations using MSN messengers in wired environments. Thus, the instant message service has been introduced into terminals and networks based on the SIP / IP core network. According to the needs of customers and enterprises for Push To Talk (PTT) (that is, walkie-talkie), developed a wireless Push To Talk (PTT over Cellular, PoC) service and system based on SIP / IP core network .According to rapid changes in the en...
