    • A synchronizing method for bearer switching and bearer releasing in VCC(Voice Call Continuity), its UE(User Equipment) and its network server are provided to allow a VCC AS(Application Server) of a network to release resources related to a domain transfer because the VCC AS can recognize a time point at which a UE will perform switching to a transferred-in domain through a specific signal. When a user plane is updated according to a domain transfer of an ongoing call or session, a UE receives a response message to updating of the user plane from a network server. The UE switches the user plane or a bearer from a transferred-out domain to a transferred-in domain. The UE transmits the first information indicating the completion of switching of the user plane or the bearer to the first network server. The network server releases a bearer of the transferred-out domain based on the first information received from the UE.
    • 提供VCC(语音呼叫连续性),其UE(用户设备)及其网络服务器中的承载交换和承载释放的同步方法,以允许网络的VCC AS(应用服务器)释放与域传输相关的资源,因为 VCC AS可以识别UE将通过特定信号执行切换到转入域的时间点。 当根据正在进行的呼叫或会话的域转移更新用户平面时,UE从网络服务器接收到更新用户平面的响应消息。 UE将用户平面或承载从转出域切换到转入域。 UE向第一网络服务器发送指示用户平面或承载的完成切换的第一信息。 网络服务器基于从UE接收到的第一信息来释放被转出域的承载。
