信息技术 系统间远程通信和信息交换 专用综合业务网 规范、功能模型和信息流 无线终端呼叫处理附加网络特性

[中文适用范围]： 本国际标准规定了无线终端呼叫处理附加网络功能（ANF-WTMI、ANF-WTMO），这些功能适用于专用综合业务网络（PISN）支持的各种基本服务。 ISO/IEC 11574 中规定了基本服务。 附加网络功能 无线终端呼入呼叫 (ANF-WTMI) 将呼入呼叫定向到 PISN 内的 WTMI 用户，无论 WTMI 用户在 PISN 内的地理位置如何，前提是已知 WTMI 用户的位置。 附加网络功能 无线终端呼出呼叫 (ANF-WTMO) 检测来自 WTMO 用户的呼出呼叫并将其建立为基本呼叫，无论用户在 PISN 内的地理位置如何。 它还提供 WTMO 用户的服务配置文件以供拨出呼叫控制使用，或者将呼叫传递到 WTMO 用户的归属位置进行处理。 根据 CCITT 建议 I.130 中描述的方法，服务规范分三个阶段制定。 本国际标准包含 ANF-WTMI 和 ANF-WTMO 第 1 阶段和第 2 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。 第 2 阶段规范（第 8 条和第 9 条）标识了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 Wireless terminal call handling additional network features (ANF-WTMI, ANF-WTMO), which are applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574. Additional network feature Wireless terminal incoming call (ANF-WTMI) directs incoming calls to a WTMI user within a PISN regardless of the WTMI user's geographical location within the PISN, provided the WTMI user's location is known. Additional network feature Wireless terminal outgoing call (ANF-WTMO) detects an outgoing call from a WTMO user and establishes it as a basic call, regardless of the user's geographical location within the PISN. It also provides the WTMO user's service profile for use by outgoing call control, or alternatively passes the call to the WTMO user's home location for processing. Service 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 ANF-WTMI and ANF-WTMO. The stage 1 specification (clauses 6 and 7) specifies the service as seen by users of PISNs. The stage 2 specification (clauses 8 and 9) identifies the functional entities involved in the service and the information flows between them.
