    Abstract: A method and apparatus are provided for handing over from a Long Term Evolution (LTE) network to a Circuit Switching (CS) network by a call manager in a wireless communication system. The method includes receiving, from an Enhanced Node B (ENB) of the LTE network, a handover required message for a Packet Switching (PS) to CS handover from the LTE network to the CS network, when the PS to CS handover is decided based on measurement reports of a User Equipment (UE); sending, to a Mobile Switching Center (MSC) of the CS network, a PS to CS handover request message including an International mobile subscriber identity (IMSI) for identifying the UE and a target IDentifier (ID) for a target cell of the CS network; receiving a PS to CS handover response message from the MSC; and sending, to the UE via the ENB, a handover command message.

    Abstract: Methods and apparatuses are provided for providing a voice call service in a Circuit Switching (CS) domain to a User Equipment (UE) being in a Packet Switching (PS) domain in a mobile communication system. A first message for paging to provide the voice call service in the CS domain to the UE is sent to an evolved Node B (eNB) in the PS domain. A second message including a cause associated with a domain change from the PS domain to the CS domain, is received from the eNB. A third message requesting suspension of the service being provided to the UE in the PS domain, is sent to a gateway in the PS domain.

    Abstract translation: 提供了用于在电路交换（CS）域中向位于移动通信系统中的分组交换（PS）域中的用户设备（UE）提供语音呼叫服务的方法和设备。 用于寻呼以将CS域中的语音呼叫服务提供给UE的第一消息被发送到PS域中的演进节点B（eNB）。 从eNB接收到包括与从PS域到CS域的域改变相关联的原因的第二消息。 请求暂停在PS域中向UE提供的服务的第三消息被发送到PS域中的网关。

    Abstract: A method and apparatus is provided for communication between a first terminal capable of using both a Circuit Switched (CS) call and an Internet Protocol Multimedia Subsystem (IMS) session, and a second terminal capable of using the IMS session, in a communication system supporting a Combined CS call and IMS session (CSI service). If the second terminal sends a Session Initiation Protocol (SIP) request (INVITE) message to originate a voice service or a multimedia service including the voice service with the first terminal, a CSI Application Server (AS) of an IMS domain managing the first terminal separates a voice service-related component included in the request message from a multimedia service-related component, and generates and sends first and second request messages to the first terminal. Upon receipt of first and second response messages corresponding to the first and second request messages from the first terminal, the CSI AS generates a combined response message and sends the combined response message to the second terminal.

    Abstract: A method, performed by a mobile management entity (MME), for providing a voice call service to a user equipment (UE) in a mobile communication system and the MME are provided. The method includes receiving, from a mobile management entity (MME), a first message for paging to provide the voice call service to the UE; and sending, to the MME, a second message including a cause associated with a domain change from a packet switching (PS) domain to a circuit switching (CS) domain, wherein, if the MME receives the second message, a third message for requesting suspension of a bearer to provide a service for the UE is sent to a gateway in the PS domain.
