    • 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.
    • 提供一种方法和装置,用于在能够使用电路交换(CS)呼叫和因特网协议多媒体子系统(IMS)会话的第一终端和能够使用IMS会话的第二终端之间进行通信,所述通信系统支持 组合CS呼叫和IMS会话(CSI服务)。 如果第二终端发送会话发起协议(SIP)请求(INVITE)消息以产生包括与第一终端的语音服务的语音服务或多媒体服务,则管理第一终端的IMS域的CSI应用服务器(AS) 将包括在请求消息中的语音服务相关组件与多媒体业务相关组件分离,并产生并向第一终端发送第一和第二请求消息。 在接收到来自第一终端的与第一和第二请求消息对应的第一和第二响应消息时,CSI AS生成组合的响应消息,并将组合的响应消息发送到第二终端。
