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 参考点处支持无线终端认证补充业务（SS-WTAT 和 SS-WTAN）的信令协议。 ）。 WTM 用户身份验证 (SS-WTAT) 是一项补充服务，作为一项安全措施，PISN 可以验证 WTM 用户提供的身份。 PISN 身份验证 (SS-WTAN) 是一项补充服务，作为一项安全措施，使所服务的 WTM 用户能够验证 PISN 的身份。 这些服务中使用的机制基于身份验证的质询和响应方法。 这些补充服务使用的认证算法不属于本国际标准的范围。 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 15432 中第 1 阶段和第 2 阶段规范确定的要求。 SS-WTAT 和 SS-WTAN 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支持 SS-WTAT / SS-WTAN 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。 本国际标准适用于可以互连形成 PISN 的 PINX。 [外文原描述]： ISO/IEC 15433:2003 specifies the signalling protocol for the support of the Wireless Terminal Authentication supplementary services (SS-WTAT and SS-WTAN) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). Authentication of a WTM user (SS-WTAT) is a supplementary service that enables a PISN, as a security measure, to validate the identity provided by the WTM user. Authentication of the PISN (SS-WTAN) is a supplementary service that enables a served WTM user, as a security measure, to validate the identity of the PISN. The mechanisms used in these services are based on the challenge and response method of authentication. Authentication algorithms to be used by these supplementary services are outside the scope of this International Standard. 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. 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 15432. The signalling protocol for SS-WTAT and SS-WTAN uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582. ISO/IEC 15433:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-WTAT / SS-WTAN and other supplementary services and ANFs. ISO/IEC 15433:2003 is applicable to PINXs which can interconnect to form a PISN.
