标准范围

ISO/IEC 15506:2003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参考点处支持消息等待指示补充业务(SS-MWI)的信令协议。补充业务MWI使得被服务用户能够被发送消息等待指示，并且还使得该消息等待指示能够被取消。还可以允许被服务用户向消息中心询问任何消息等待指示。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 15505中第1阶段和第2阶段规范确定的要求。SS-MWI的信令协议使用ISO/IEC 11582中规定的用于控制补充服务的通用程序的某些方面。ISO/IEC 15506:2003还规定了额外的信令协议要求，以支持SS-MWI与其他补充服务和ANF之间在Q参考点处的交互。注:对Q参考点处的信令协议没有影响的其他交互可以在相关的第1阶段规范中找到。ISO/IEC 15506:2003适用于可以互连形成PISN的PINX。

ISO/IEC 15506:2003 specifies the signalling protocol for the support of the Message Waiting Indication supplementary service (SS-MWI) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN).

The supplementary service MWI enables a Served User to be sent a Message Waiting Indication and also enables this Message Waiting Indication to be cancelled. The Served User may also be permitted to interrogate the Message Centre for any Message Waiting Indication.

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 15505.

The signalling protocol for SS-MWI uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582.

ISO/IEC 15506:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-MWI 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 15506:2003 is applicable to PINXs which can interconnect to form a PISN.
