    • A service triggering system and method for performing service triggering in an Internet protocol (IP) multimedia subsystem based on any message upon a call setup request in an IMS network are provided, in which a call session control function (CSCF) processes service triggering based on all messages, to which filter criteria (FC) information required for the service triggering is applied, upon a call setup, a home subscriber server (HSS) provides the filter criteria to the call session control function upon registration of a subscriber, an application server performs a call processing for providing a transcoding service, when an originating user equipment and a terminating user equipment use different codecs, and a media resource function performs a transcoding operation in accordance with different codecs between the originating user equipment and the terminating user equipment.

    • A system and method are provided for interworking between an Internet Protocol (IP) Multimedia Core Network Subsystem (IMS) network that provides an IP multimedia service to at least one first terminal, and an H.323 network that provides a packet switched multimedia service to at least one second terminal. In the system and method, upon receiving an invite message from the first terminal, a Call Session Control Function (CSCF) determines whether the second terminal is a terminal serviceable via the H.323 network through a query with a Domain Name Server (DNS). If the second terminal is a terminal serviceable via the H.323 network, the CSCF transmits an invite message including codec information of the first terminal to an interworking function (IWF), and sends a request for a transcoding service to a transcoding unit upon receiving from the IWF a response message including a codec list supportable by the H.323 network. Upon receiving an invite message including transcoding information from the transcoding unit via the CSCF, the IWF translates the invite message into a call setup message and transmits the call setup message to the H.323 network. Upon receiving the call setup message from the IWF, a gatekeeper sets up a call to the IMS network.
    • 提供了一种用于在向至少一个第一终端提供IP多媒体业务的因特网协议(IP)多媒体核心网络子系统(IMS)网络和提供分组交换多媒体业务的H.323网络之间进行互通的系统和方法, 至少一个第二终端。 在系统和方法中,在从第一终端接收到邀请消息时,呼叫会话控制功能(CSCF)通过具有域名服务器(DNS)的查询来确定第二终端是否经由H.323网络可维修的终端, 。 如果第二终端是通过H.323网络可以使用的终端,则CSCF向互通功能(IWF)发送包括第一终端的编解码信息的邀请消息,并且在接收到转发服务时向转码单元发送转发服务请求 来自IWF的响应消息包括可由H.323网络支持的编解码器列表。 IWF经由CSCF接收到来自代码转换单元的代码转换信息的邀请消息时,IWF将邀请消息转换成呼叫建立消息,并将呼叫建立消息发送到H.323网络。 在从IWF接收到呼叫建立消息时,网守建立到IMS网络的呼叫。
