IP增值业务系统管理机制的研究

通过分析现有基于H.323的IP电话系统集中式管理机制在增值业务管理中的不足，提出了将软交换的控制与业务相分离的思想引入系统管理的新思路，建立起包含系统全局域管理、增值业务内部的呼叫控制与业务流程管理，直至增值业务底层的多媒体交互控制与管理的分级系统管理机制，讨论了其中域管理的实现方式，并在实际系统中进行了验证．

Research on system management of IP supplementary services

After analysis of three main problems in the manageme nt of supplementary services in IP tele- phony system, a graded system managem ent me chanism was proposed based on the separation of call control and services from s oftswitch technology. This mechanism consisted of three-level management includ ing system overall zone managing, service controlling and flow managing in suppl ementary service and multimedia interaction controlling and managing in the base level of service. The system overall zone management accomplished by gatekeeper and series of support functions in supplementary services server was described. After being applied into reality and testing, the graded management mechanism w as confirmed with service expansion and controllability and system software arch itecture stability and modularization.
