标准摘要
[中文适用范围]： 本国际标准规定了无线终端位置注册补充业务（SS-WTLR）和无线终端信息交换附加网络功能（ANF-WTINFO），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。 无线终端位置注册补充服务 (SS-WTLR) 使 WTM 用户能够在 PISN 内的当前位置注册或取消注册。 在不同时间在 PISN 中的不同位置注册的能力使 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（包括接听来电）。 信息交换附加网络功能 (ANF-WTINFO) 允许在归属数据库和访客数据库之间交换有关 WTLR 用户的信息。 根据CCITT建议I.130中描述的方法，补充服务和附加网络特征规范分三个阶段产生。 本国际标准包含SS-WTLR和ANF-WTINFO的第一阶段和第二阶段规范。 第一阶段规范（第 6 条和第 7 条）指定了 PISN 用户所看到的服务/功能。 第 2 阶段规范（第 8 条和第 9 条）标识了服务/特性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 Wireless Terminal Location Registration supplementary service (SS-WTLR) and the Wireless Terminal Information Exchange additional network feature (ANF-WTINFO), which are applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574. The Wireless Terminal Location Registration Supplementary Service (SS-WTLR) enables a WTM user to register at, or de-register 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. De-registration is used to inform the PISN that the WTM user is temporarily unable to make use of the provided services (including the receipt of incoming calls). The Information Exchange Additional Network Feature (ANF-WTINFO) allows to exchange information about a WTLR user between the Home Data Base and the Visitor Data Base. Supplementary service and additional network feature specifications are produced in three stages, according to the method described in CCITT Recommendation I.130. This International Standard contains the stage 1 and stage 2 specifications of SS-WTLR and ANF-WTINFO. The stage 1 specification (clause 6 and 7) specifies the service/feature as seen by users of PISNs. The stage 2 specification (clause 8 and 9) identifies the functional entities involved in the service/feature and the information flows between them.
