标准范围
ISO/IEC 13869:2003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参考点处的呼叫转移补充业务(SS-CT)的信令协议。SS-CT是一种补充业务，它使用户能够将该用户的两个呼叫(其中至少一个必须被应答)转换为两个呼叫中的另外两个用户之间的新呼叫。Q参考点在ISO/IEC 11579-1中定义。根据ETS 300 387中规定的方法，分三个阶段制定服务规范。ISO/IEC 13869:2003包含Q参考点的第3阶段规范，并满足ISO/IEC 13865中第1阶段和第2阶段规范确定的要求。用于SS-CT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 13869:2003还规定了用于支持呼叫转移和其他补充业务与ANF之间在Q参考点处的交互的附加信令协议要求。ISO/IEC 13869:2003适用于可以互连以形成PISN的PINX。
ISO/IEC 13869:2003 specifies the signalling protocol for the support of the Call Transfer supplementary service (SS-CT) at the Q reference point between Private Integrated Network services eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN).
SS-CT is a supplementary service which enables a User to transform two of that User's calls (at least one of which must be answered) into a new call between the two other users in the two calls.
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 ETS 300 387. ISO/IEC 13869:2003 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 13865.
The signalling protocol for SS-CT 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 13869:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between Call Transfer and other supplementary services and ANFs.
ISO/IEC 13869:2003 is applicable to PINXs which can interconnect to form a PISN.
