中文摘要:
      随着智慧广电概念的提出,基于广电网络的IMS业务应运而生。为了实现IMS业务事前可感知、事中可管控、事后可追溯的目标,设计并实现了基于广电IMS业务的仿真测试系统。仿真测试系统分为SIP子系统、监测子系统、拨测子系统和管理子系统4部分,采用协议栈构造、鱼骨分析算法、信令流程跟踪和数据挖掘作为关键技术,仿真IMS核心网中的各个网元,实现多接口接入测试,填补了广电行业相关领域的空白。通过仿真测试系统,实现业务自动化测试,实时监测IMS网络的业务质量,从而为业务的运行维护提供标准化支撑。
英文摘要:
      With the concept of smart radio and television,IMS service based on radio and television network came into being.To achieve the goal of perceiving IMS service in advance,controlling it in the process and tracing it after the event,a simulation test system based on IMS service is designed and implemented.The simulation and test system is divided into four subsystems: SIP,monitoring,dial test,and management.The protocol stack construction,fishbone analysis algorithm,signaling process tracking and data mining are used as key technologies to simulate each network element in the IMS core network,realizing multi-interface access test,and filling in the gaps in related fields of radio and television industry.Through the simulation test system,the automatic test of business is realized,the business quality of IMS network in real time is monitored,thus providing a standardized support for the operation and maintenance.
