标准范围

ISO/IEC 17878:2003规定了用于支持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参考点处处理附加网络特征(ANF-PUMI和ANF-PUMO)的专用用户移动性呼叫的信令协议。ANF-PUMI是一种将传入呼叫定向到PISN内的PUM用户的特征，只要PUM用户的位置是已知的。如果需要，ANF-PUMO允许PISN处理来自归属位置的PUM用户的呼叫请求。Q参考点在ISO/IEC 11579-1中定义。服务规范分三个阶段产生，并根据ITU-T Rec中规定的方法。I.130.ISO/IEC 17878:2003包含Q参考点的第3阶段规范，并满足ISO/IEC 17877中第1阶段和第2阶段规范确定的要求。用于ANF-PUMI和ANF-PUMO的信令协议在用于基本电路交换呼叫控制的信令协议之上运行，如在ISO/IEC 11572中所规定的，并且使用用于控制在ISO/IEC 11582中所规定的补充业务的通用程序的某些方面。ISO/IEC 17878:2003还规定了用于支持ANF-PUMI/ANF-PUMO和其他补充业务与ANF之间的Q参考点处的交互的附加信令协议要求。ISO/IEC 17878:2003适用于可以互连以形成PISN的PINX。

ISO/IEC 17878:2003 specifies the signalling protocol for the support of the Private User Mobility call handling additional network features (ANF-PUMI and ANF-PUMO) at the Q reference point between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN).

ANF-PUMI is a feature that directs incoming calls to a PUM user within the PISN regardless of the PUM user's geographical location within the PISN, provided that the PUM user's location is known.

ANF-PUMO permits the PISN to process call requests from a PUM user at the home location, if required.

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. ISO/IEC 17878:2003 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 17877.

The signalling protocol for ANF-PUMI and ANF-PUMO 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 17878:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between ANF-PUMI/ANF-PUMO and other supplementary services and ANFs.

ISO/IEC 17878:2003 is applicable to PINXs which can interconnect to form a PISN.
