标准范围
ISO/IEC 14846:2003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参考点处支持呼叫入侵补充业务(SS-CI)的信令协议。SS-CI是一种补充业务,它根据主叫用户的请求,使主叫用户能够通过中断被叫用户和第三用户(不需要的用户)之间的已建立呼叫来与忙碌的被叫用户建立通信。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。本国际标准包含Q参考点的第3阶段规范,并满足ISO/IEC 14845中第1阶段和第2阶段规范确定的要求。用于SS-CI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,并使用用于控制ISO/IEC 11582中所规定的补充业务的通用程序的某些方面。ISO/IEC 14846:2003还规定了支持SS-CI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。注:在相关的第1阶段规范中可以找到对Q参考点处的信令协议没有影响的附加交互。ISO/IEC 14846:2003适用于可以互连形成PISN的PINX。
ISO/IEC 14846:2003 specifies the signalling protocol for the support of the Call Intrusion supplementary service (SS-CI) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN).
SS-CI is a supplementary service which, on request from the calling user, enables the calling user to establish communication with a busy called user by breaking into an established call between the called user and a third user (unwanted user).
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. 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 14845.
The signalling protocol for SS-CI 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 14846:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-CI and other supplementary services and ANFs.
NOTE Additional interactions that have no impact on the signalling protocol at the Q reference point can be found in the relevant stage 1 specifications.
ISO/IEC 14846:2003 is applicable to PINXs which can interconnect to form a PISN.
