Abstract:
A method of performing inter-user equipment (UE) transfer (IUT) by an Internet protocol (IP) multimedia subsystem (IMS) network in an IMS-based network system is provided. The method includes receiving from a first UE a subscription message for requesting notification of state or capability information of another UE, transmitting to the first UE a subscription acceptance message in response to the subscription message, receiving from a second UE a control message comprising an IUT flag for indicating IUT enable or disable for media flows, and transmitting to the first UE a notification message comprising information on the second UE, if the IUT flag indicates IUT enable for the media flows. It is possible to decrease a signaling overhead caused by a failure of IUT of a media flow.
