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 参考点处支持公共信息附加网络功能（ANF-CMN）的信令协议。 ANF-CMN 是一项附加网络功能，可通过 PISN 在代表连接两端的实体之间交换公共信息。 该公共信息是与连接一端的用户或设备相关的杂项信息的集合，包括以下一项或多项：功能标识符、参与方类别、设备身份。 当实体接收到该信息时，该信息可以用于任何目的，例如作为向本地用户或另一个网络的指示的基础或者为了过滤特征请求。 Q 参考点在 ISO/IEC 11579-1 中定义。 附加网络功能规范按照 ETS 300 387 中描述的方法分三个阶段生成。 该国际标准包含 Q 参考点的第 3 阶段规范，并满足 ISO/IEC 中第 1 阶段和第 2 阶段规范确定的要求15771. ANF-CMN 的信令协议在基本电路交换呼叫控制的信令协议之上运行，如 ISO/IEC 11572 中所规定，并使用 ISO/IEC 中规定的补充服务控制通用过程的某些方面11582. 该国际标准还规定了额外的信令协议要求，以支持 ANF-CMN 与其他补充服务和 ANF 之间 Q 参考点的交互。 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。 [外文原描述]： ISO/IEC 15772:2003 specifies the signalling protocol for the support of the Common Information additional network feature (ANF-CMN) at the Q reference point between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN). ANF-CMN is an additional network feature which enables the exchange of Common Information between entities acting on behalf of the two ends of a connection through a PISN. This Common Information is a collection of miscellaneous information that relates to the user or equipment at one end of a connection and includes one or more of the following: Feature Identifiers, Party Category, Equipment Identity. This information, when received by an entity, can be used for any purpose, e.g. as the basis for indications to the local user or to another network or in order to filter feature requests. The Q reference point is defined in ISO/IEC 11579-1. Additional network feature specifications are produced in three stages and according to the method described in ETS 300 387. 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 15771. The signalling protocol for ANF-CMN operates on top of the signalling protocol for basic circuit switched call control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. ISO/IEC 15772:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between ANF-CMN and other supplementary services and ANFs.
