标准范围

ISO/IEC 20113:2004规定了补充业务呼叫请求（SS-MCR），该请求与但不限于专用综合业务网络（PISN）支持的各种基本业务相关。ISO/IEC 11574规定了基本服务。补充业务MCR使得请求用户能够请求合作用户向目的地用户建立新的请求呼叫。合作用户和目的地用户之间新请求的呼叫可以是基本呼叫，也可以是独立于呼叫的信令连接。根据ETS 300 387中描述的方法，服务规范分三个阶段制定。ISO/IEC 20113:2004包含SS-MCR的第1阶段和第2阶段规范。第一阶段规范规定了PISNs用户看到的补充业务。阶段2规范规定了补充业务中涉及的功能实体以及它们之间的信息流。

ISO/IEC 20113:2004 specifies supplementary service Make Call Request (SS-MCR), which is related, but not limited to, various basic services supported by Private Integrated Services Networks (PISNs). Basic services are specified in ISO/IEC 11574.The supplementary service MCR enables a Requesting User to request a Co-operating User to establish a new Requested Call to a Destination User. This new Requested Call between the Co-operating and Destination User can be either a Basic call or call independent signalling connection.Service specifications are produced in three stages, according to the method described in ETS 300 387. ISO/IEC 20113:2004 contains the stage 1 and stage 2 specifications of SS-MCR. The stage 1 specification specifies the supplementary service as seen by users of PISNs. The stage 2 specification specifies the functional entities involved in the supplementary service and the information flows between them.
