标准范围

ISO/IEC 15431:2003规定了用于支持无线终端呼叫处理附加网络特征(ANF-WTMI和ANF-WTMO)的信令协议，所述无线终端呼叫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。ANF-WTMI是将呼入呼叫引导到PISN内的WTMI用户的特征，只要WTMI用户的位置是已知的。在PISN之外漫游不在本国际标准的本版范围内。如果需要，ANF-WTMO允许PISN在归属位置处理来自WTMO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建议。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 15430中第1阶段和第2阶段规范确定的要求。用于ANF-WTMI和ANF-WTMO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 15431:2003还规定了用于支持ANF-WTMI/ANF-WTMO与其他补充业务和ANF之间的Q参考点处的交互的附加信令协议要求。ISO/IEC 15431:2003适用于可以互连以形成PISN的PINX。

ISO/IEC 15431:2003 specifies the signalling protocol for the support of the Wireless terminal call handling additional network features (ANF-WTMI and ANF-WTMO) at the Q reference point between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN).

ANF-WTMI is a feature that directs incoming calls to a WTMI user within the PISN regardless of the WTMI user's geographical location within the PISN, provided that the WTMI user's location is known. Roaming outside the PISN is outside the scope of this edition of this International Standard.

ANF-WTMO permits the PISN to process call requests from a WTMO 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. 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 15430.

The signalling protocol for ANF-WTMI and ANF-WTMO 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 15431:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between ANF-WTMI / ANF-WTMO and other supplementary services and ANFs.

ISO/IEC 15431:2003 is applicable to PINXs which can interconnect to form a PISN.
