    • Disclosed is a method in which in case where it is inappropriate for a particular Home (e)NodeB providing a service to a particular UE to continue to provide the service on the ground of a changed status, such as overload, temporary drop due to maintenance, expiry of CSG membership for the UE, increase of temporary interference, policy change, or the like, the Home (e)NodeB transmits information on a cause that the UE performs a handover to another base station to an control entity within a network. Furthermore, it is allowed for the entity within the network to store information on the cause. In addition, if the status of the particular Home (e)NodeB is changed, then the entity within the network is allowed to perform a reverse handover for the UE to the particular Home (e)NodeB on the basis of the information on the changed status and the information on the cause.

    • According to the present invention, a service operator can immediately transfer an ongoing session to another network, accordingly it is capable of dealing with cases that a network is required to be temporarily stopped due to repairing/checking for the network, it is required to perform a network load balancing, it is required to more effectively perform the ongoing session, and the policy of the service operator is changed. And, according to the present invention, when the ongoing session is required to be transferred later even though it is not required to be immediately transferred, or session continuity operator policy is changed, it is capable of sending the session continuity operator policy to the terminal and then allowing the terminal to transfer the ongoing session to another network according to determination by itself.
    • 根据本发明,服务运营商可以立即将正在进行的会话转移到另一网络,因此能够处理由于网络的修复/检查而要求网络临时停止的情况,需要执行 网络负载平衡,需要更有效地执行正在进行的会话,并且更改服务运营商的策略。 而且,根据本发明,即使不需要立即传送正在进行的会话,即使不需要立即传送,也可以将会话连续性运营商策略变更,能够向终端发送会话连续性运营商策略 然后允许终端根据自身的确定将正在进行的会话传送到另一个网络。

    • A session mobility support is disclosed. An application server (AS) can accurately recognize a session update by checking a Replace header, a user ID and a media element included in a session invitation message (or an SIP-based INVITE message) received from a UE (User Equipment), to thus guarantee successful mobility of a session. In addition, in order to allow the AS to accurately recognize the session update, the UE first transmits the session invitation message including the Replace header via a PS (Packet Switching domain, and then, after a response to the session invitation message is received, the UE transmits a call setup message (e.g., SETUP message) via a CS (Circuit Switching) domain.
    • 会议移动性支持被披露。 应用服务器(AS)可以通过检查从UE(用户设备)接收的会话邀请消息(或基于SIP的INVITE消息)中包括的替换报头,用户ID和媒体元素来准确地识别会话更新, 从而保证一个会话的成功移动。 另外,为了使AS能够准确地识别会话更新,UE首先通过PS(分组交换域)发送包括替换报头的会话邀请消息,然后在接收到对会话邀请消息的响应之后, UE经由CS(电路交换)域发送呼叫建立消息(例如,SETUP消息)。
