摘要
提出了一种可支持IN/IP业务互通的软交换功能组件—智能业务代理ISA,描述了该组件在智能网功能体系结构中的位置和作用;讨论了采用叠加技术构造智能业务代理呼叫状态机的机理,以及IN基本呼叫模型BCSM与IP电话呼叫模型的对应关系,并以现有的典型智能网业务-800号业务为例,说明了智能业务代理ISA完成呼叫状态的对应和呼叫消息及参数的转换的原理.
An Softswitch component-Intelligent Services Agent (ISA) supporting of IN/IP inter-working is proposed. Overlaid scheme which is used to build ISA is discussed. Some key technical issues, such as call states mapping and Messages conversion schemes, are presented. A free phone service in IN/IP inter-working environment is shown as an example to illustrate the ISA's working scenario.
