标准范围

ISO/IEC 20114:2004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(PINXs)之间的Q参考点处支持呼叫请求补充业务(SS-MCR)的信令协议。补充业务MCR使请求用户能够请求合作用户建立到目的地用户的新的请求呼叫。协作用户和目的地用户之间的新请求呼叫可以是基本呼叫或呼叫独立信令连接。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 20114:2004包含Q参考点的第3阶段规范，并满足ISO/IEC 20113中第1阶段和第2阶段规范确定的要求。用于SS-MCR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中所规定的补充服务的通用程序的某些方面。ISO/IEC 20114:2004还规定了用于支持SS-MCR和其他补充服务和ANF之间的Q参考点处的交互的附加信令协议要求。ISO/IEC 20114:2004适用于可以互连以形成PISN的PINX。

ISO/IEC 20114:2004 specifies the signalling protocol for the support of the Make Call Request supplementary service (SS-MCR) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN).

Supplementary service MCR enables a Requesting User to request a Co-operating User to establish a new Requested Call to a Destination User. This new Requested Call between the Co-operating and Destination User can be either a Basic call or a Call Independent Signalling Connection.

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 20114:2004 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 20113.

The signalling protocol for SS-MCR 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 20114:2004 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-MCR and other supplementary services and ANFs.

ISO/IEC 20114:2004 is applicable to PINXs, which can interconnect to form a PISN.
