软交换INAP业务适配系统的设计实现

为了保护运营商在智能网(IN)方面的前期大量投资,软交换系统必须能够与原有智能网进行互通,并继承智能网原有的业务,智能网应用规程(INAP)业务适配系统即应此而生。INAP业务适配系统与呼叫控制系统、事务处理能力应用部分(TCAP)协议栈应用程序通信,完成INAP和私有协议之间的转换和映射。INAP业务适配系统由核心(CORE)、远程业务接入管理(RSAM)和TCAP接口管理(TIM)3个模块构成,其工作原理、总体结构、初始化、消息处理以及模块设计和实现均有说明。

Design and Implementation of Soft Switch INAP Service Adaptive System

To protect the large amount of preliminary investment of telecom operators in Intelligent Network （IN）, soft switch system is required to be able to intercommunicate with existing INs, and inherits the services of them. Thus, the Intelligent Network Application Protocol （INAP） Service Adaptive System emerges. The INAP Service Adaptive System communicates with the Call Control System as well as the Transaction Capability Application Part （TCAP） Protocol Stack Application Program, and completes the mapping and translation between the INAP and the private protocols. The INAP Service Adaptive System consists of three modules,i, e. CORE, Remote Service Access Management （RSAM） and TCAP Interface Management （TIM）. The operation principle, general structure, initialization, message processing as well as module design and implementation of the INAP Service Adaptive System are described.
