采用CPH技术实现铁路专用通信系统中多方通信功能的研究

Study on Realizing the Special Railway Multiparty Communication System by CPH Technology

提出了用智能网技术实现目前铁路专用通信业务的方法,并重点研究分析了利用智能网CS-2中的CPH(呼叫方处理)能力,来实现多方通信及通信过程中的控制的模式结构和方法,并给出了用此方法实现多方通信的实例。同时根据智能网技术的特点,以这种方式实现的铁路专用通信系统可与数据网互联,便于拓展业务,前景广阔。

In the paper a method is put forward to realize the spee control during multiparty calls, so the models and scheme to realize and control multiparty calls with the Call Party Handling capability in IN are analyzed in detail, and a multiparty calls sample was carry out in this way . At last , according to the feature of IN technology, this method gives some good ways to interwork with other data networks and it is convenient to develop the new services.
