A method is provided for transferring a session between multiple devices by a target device, in which the target device selects a particular session of a source device and sends a request for session transfer for the selected session to a call server, the target device acquires from the call server data that has been transmitted from the remote party's device of the particular session and temporarily stored in the call server after the session transfer request, and the target device sends a message indicating completed acquisition of the temporarily stored data to the call server, and receives the particular session transferred in response thereto.

Method for transferring session in converged Internet protocol messaging system

A converged IP messaging client transmits a session establishment request for interactive message communication. When a converged IP messaging server receives the request, it determines whether a target client of the interactive message communication uses a converged IP messaging service. If not, the converged IP messaging server transmits the session establishment request to an IWF. If it is determined that the target client is an SM client, the IWF generates an interactive message communication request by transforming a format of the session establishment request into an SMS format and transmits the interactive message communication request to the SM client. If the IWF receives an acceptance response from the SM client in response to the interactive message communication request within an effective response time, a session for the interactive message communication can be established between the converged IP messaging client and the SM client.
