标准摘要
[中文适用范围]： 本国际标准规定了补充业务（SS）专用用户移动注册（PUMR），适用于专用综合业务网络（PISN）支持的各种基础业务。 ISO/IEC 11574 中规定了基本服务。 SS-PUMR 是一项补充服务，使 PUM 用户能够在 PISN 内的任何有线或无线终端上注册或取消注册。 在不同时间在PISN中的不同有线和无线终端注册的能力使得PUM用户能够在不同接入点维持所提供的服务（包括拨打和接听呼叫的能力）。 根据 CCITTRec 中描述的方法，补充服务规范分三个阶段生成。 I.130。 本国际标准包含 SS-PUMR 的第 1 阶段和第 2 阶段规范。 第一阶段规范（第 6 条）指定了一般功能原则和功能。 第 2 阶段规范（第 7 条）标识了补充服务中涉及的功能实体以及它们之间的信息流。 [外文原描述]： This International Standard specifies the Supplementary Service (SS) Private User Mobility Registration (PUMR), which is applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574. SS-PUMR is a supplementary service that enables a PUM user to register at, or de-register from, any wired or wireless terminal within the PISN. The ability to register at different wired and wireless terminals in the PISN at different times enables the PUM user to maintain the provided services (including the ability to make and receive calls) at different access points. Supplementary service specifications are produced in three stages, according to the method described in CCITT Rec. I.130. This International Standard contains the stage 1 and stage 2 specifications of SS-PUMR. The stage 1 specification (clause 6) specifies the general feature principles and capabilities. The stage 2 specification (clause 7) identifies the Functional Entities involved in the supplementary service and the information flows between them.
