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交换（PINX）之间的 Q 参考点支持无线终端位置注册补充服务（SS-WTLR）和无线终端信息交换附加网络功能（ANF-WTINFO）的信令协议。 ）在专用综合服务网络（PISN）内连接在一起。 SS-WTLR 是一项补充服务，使 WTM 用户能够在 PISN 内的当前位置注册或注销。 在不同时间在 PISN 中的不同位置注册的能力使 WTM 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 WTM 用户暂时无法使用所提供的服务（包括接听电话）。 ANF-WTINFO 是一项附加网络功能，可在归属 PINX 和访客 PINX 之间传输限制信息。 ANF-WTINFO 还使访客 PINX 或家庭 PINX 能够启动对当前位置信息的检查。 Q 参考点在 ISO/IEC 11579-1 中定义。 补充服务规范和附加网络功能规范按照 ITU-T Rec. 2 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 15428 中第 1 阶段和第 2 阶段规范确定的要求。 SS-WTLR 和 ANF-WTINFO 的信令协议使用通用程序的某些方面用于控制 ISO/IEC 11582 中规定的补充业务。 该国际标准还规定了额外的信令协议要求，以支持 SS-WTLR 与其他补充业务和 ANF 之间在 Q 参考点处的交互。 本国际标准适用于可以互连形成 PISN 的 PINX。 [外文原描述]： ISO/IEC 15429:2003 specifies the signalling protocol for the support of the Wireless Terminal Location Registration supplementary service (SS-WTLR) and the Wireless Terminal Information exchange additional network feature (ANF-WTINFO) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). SS-WTLR is a supplementary service which enables a WTM user to register at, or deregister from, the current location within the PISN. The ability to register at different locations in the PISN at different times enables the WTM user to maintain the provided services (including the ability to make and receive calls) at different access points. Deregistration is used to inform the PISN that the WTM user is temporarily unable to make use of the provided services (including the receipt of calls). ANF-WTINFO is an additional network feature which enables transfer of restriction information between Home PINX and Visitor PINX. ANF-WTINFO also enables the Visitor PINX or Home PINX to initiate a check of the current location information. The Q reference point is defined in ISO/IEC 11579-1. Supplementary Service specifications and Additional Network Feature specifications are produced in three stages and according to the method specified in ITU-T Rec. I.130. This International Standard 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 15428. The signalling protocol for SS-WTLR and ANF-WTINFO uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. ISO/IEC 15429:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-WTLR and other supplementary services and ANFs. ISO/IEC 15429:2003 is applicable to PINXs which can interconnect to form a PISN.
