IMS行政交换网平滑割接方案的研究与应用

Research and Application of IMS Administrative Switching Network Smooth Cutover Scheme

IP多媒体子系统(IP Multimedia Subsystem,IMS)是下一代语音、视频、数据服务的基础架构,也是业界公认的固定和移动融合网络技术,国家电网公司已经明确使用IMS作为下一代交换网络技术。随着各省公司IMS行政交换网建设的启动,割接方案将是一大难题。IMS系统割接涉及多套系统的数据调整,配置错误有可能造成部分或者全网通信异常。传统的硬割接方案会影响业务正常使用,用户体验不佳。文章结合山东公司参与的国网IMS设备现网测试工作,提出了一种平滑割接方案,对其他网省公司IMS平滑割接具有借鉴意义。

IMS（Multimedia Subsystem IP） is the next generation services infrastructure of voice, video and data, and also recognized as the fi xed and mobile convergence network technology. SGCC has chosen IMS as the next generation switching network technology. As the IMS administrative switching network construction starts, cutover scheme will be a big problem. The IMS system switch involves multiple sets of system data adjustment, configuration errors may result in part or whole network communication abnormality. Traditional hard cutover scheme will affect the user＇s normal use. Combined with SGCC IMS network testing in Shandong Electric Power Company, this paper presents a smooth cutover scheme which has a certain reference value for developing cutover task in other provincial enterprises.
