SYSTEM AND METHOD FOR CONTROLLING SESSION MOBILITY BETWEEN TERMINALS WHEN SESSION INFORMATION IS ABSENT

摘要

Provided is a system which enables session mobility and media mobility between terminals even when the session information currently being provided is not known in advance. A method for operating a target terminal to be provided with media mobility between user terminals of a system for providing media sessions between a source terminal and a remote terminal through an IMS entity and a continuity control server, comprises the following steps: receiving user input information indicating a request for mobility of media provided through a media session between the source terminal and the remote terminal; generating a register message for requesting media mobility according to the request for mobility of media based on the user input information; and transmitting the register message to the IMS entity.
