    • A method for performing inter-user equipment (UE) transfer (IUT) of collaborative session control performed by a UE in a network system based on an Internet protocol (IP) multimedia subsystem (IMS) is provided. The method includes transmitting to an IMS network element a subscription message for requesting notification of information regarding other UE, receiving from the IMS network element a subscription acceptance message in response to the subscription message, receiving from the IMS network element a notification message comprising information regarding at least one different UE, and if a UE for transferring the collaborative session control is selected by the at least one different UE, performing a process of transferring the collaborative session control to the selected UE. A signaling overhead caused by a failure in the transfer of collaborative session control can be reduced.
    • 提供了一种用于在基于因特网协议(IP)多媒体子系统(IMS)的网络系统中执行由UE执行的协作会话控制的用户间设备(UE)传送(IUT)的方法。 该方法包括向IMS网络单元发送用于请求关于其他UE的信息的通知的订阅消息,响应于订阅消息从IMS网络单元接收订阅接收消息,从IMS网络元件接收包括关于 至少一个不同的UE,并且如果由所述至少一个不同UE选择用于传送所述协作会话控制的UE,则执行将所述协作会话控制传送到所选择的UE的过程。 可以减少由协作会话控制的转移失败引起的信令开销。

    • 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.
    • 提供了一种通过基于IMS的网络系统中的因特网协议(IP)多媒体子系统(IMS)网络执行用户间设备(UE)传送(IUT)的方法。 该方法包括从第一UE接收用于请求对另一UE的状态或能力信息的通知的订阅消息,响应于订阅消息向第一UE发送订阅接受消息,从第二UE接收包括IUT的控制消息 用于指示对于媒体流进行IUT启用或禁用的标志,以及如果所述IUT标志指示所述媒体流的IUT启用,则向所述第一UE发送包括关于所述第二UE的信息的通知消息。 可以减少由媒体流的IUT的故障引起的信令开销。
