IN/Internet互通下用户拨号接入系统的研究和设计

The Study and Design of User Dial-in System for IN Support of IP-networks

从技术实现的角度针对ITU T智能网能力集 3草案定义的智能网与因特网的互通模型的呼叫承载网关功能实体进行了研究 ,并对ITU T的智能网与因特网的互通模型作出改进。

The drafts of ITU T IN CS 3 provide a model for interworking between IN and Internet. This model divides the whole architecture into three layers(i.e. manager layer, service control layer and call/bear layers) and introduces one gateway function entity for each layer. The function entity of call/bear gateway is discussed from technique view, and a modification for the IN/Internet interworking model of ITU T is proposed. Based on this model, a design scheme of user dial in system based on today's popularly used remote dial in service system for IN support of IP networks is provided.
