标准摘要
[中文适用范围]： 本国际标准规定了在专用综合业务网络（PISN）内连接在一起的专用综合业务网络交换机（PINX）之间的 Q 参考点处支持专用用户移动注册补充服务（SS-PUMR）的信令协议。 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 中的不同位置注册的能力使 PUM 用户能够在不同的接入点维持所提供的服务（包括拨打和接听呼叫的能力）。 注销用于通知 PISN PUM 用户暂时无法使用所提供的服务（包括接听电话）。 SS-PUMR可以向PUM用户提供获取关于当前注册会话（询问）的信息的能力。 Q 参考点在 ISO/IEC 11579-1 中定义。 服务规范按照 ITU-T Rec. 中规定的方法分三个阶段制定。 I.130。 本国际标准包含 Q 参考点的第 3 阶段规范，并满足 ISO/IEC 17875 中第 1 阶段和第 2 阶段规范确定的要求。 SS-PUMR 的信令协议使用通用程序的某些方面来控制ISO/IEC 11582 中规定的补充业务。 该国际标准还规定了支持 SS-PUMR 与其他补充业务和 ANF 之间 Q 参考点交互的附加信令协议要求。 注 1 – 对 Q 参考点的信令协议没有影响的附加交互可以在相关的第 1 阶段规范中找到。 本国际标准适用于可以互连形成 PISN 的 PINX。 本国际标准仅适用于单个 PISN 内的 PUM。 [外文原描述]： ISO/IEC 17876:2003 specifies the signalling protocol for the support of the Private User Mobility Registration supplementary service (SS-PUMR) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). SS-PUMR is a supplementary service which 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 locations 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. De-registration is used to inform the PISN that the PUM user is temporarily unable to make use of the provided services (including the receipt of calls). SS-PUMR may provide the PUM user with the ability to obtain information on the current registration sessions (interrogation). The Q reference point is defined in ISO/IEC 11579-1. Service specifications are produced in three stages and according to the method specified in ITU-T Rec. I.130. ISO/IEC 17876:2003 contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 specifications in ISO/IEC 17875. The signalling protocol for SS-PUMR uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. ISO/IEC 17876:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-PUMR and other supplementary services and ANFs. NOTE Additional interactions that have no impact on the signalling protocol at the Q reference point can be found in the relevant stage 1 specifications.
