Abstract: A method to manage call continuity in a network environment including a circuit-switched network and an IP multimedia subsystem (IMS) network is provided. A UE monitors one or more ongoing sessions in an IMS network, and the ongoing sessions contain at least one conference call. The UE detects a network-switching event for the UE to switch from the IMS network to a circuit-switched CS network. The UE then determines the one or more ongoing sessions within the IMS network to be released or transferred to the CS network. Finally, the UE performs a session transfer procedure for transferring the determined sessions.

Abstract translation: 提供了一种在包括电路交换网络和IP多媒体子系统（IMS）网络的网络环境中管理呼叫连续性的方法。 UE监视IMS网络中的一个或多个正在进行的会话，并且正在进行的会话包含至少一个电话会议。 UE检测用于UE从IMS网络切换到电路交换CS网络的网络切换事件。 然后，UE确定将要释放或传送到CS网络的IMS网络内的一个或多个正在进行的会话。 最后，UE执行用于传送所确定的会话的会话转移过程。
