基于SID的IP承载网资源信息模型研究

Study on Resource Information Model for IP Bearer Network

针对电信网络运维支撑中的跨专业信息共享问题,参考SID建模方法,对IP承载网及其软交换接入网元进行分解抽象,建立了软交换服务器和媒体网关端到端关联的资源信息模型,提出了软交换接入资源调度和软交换端到端关联查询的服务模型,运用了抽象、组合、角色等设计模式,使模型能适应IP承载网结构和业务的持续演进。结合运营商的数据对模型进行系统实现,实现了MSS与MGW的端到端关联呈现,表明模型能有效支撑跨专业资源调度和告警关联分析。

Targed to solve the problem that it is difficult to share inter-department information during operation and maintaince on telecom network, referring by SID modeling method, IP bearer network and sofiswitch devices are analyzed and abstracted, and a resource information model is designed for end to end relation between MSS and MGW, and a service model is proposed for assiging resource when softswich device accessing IP brear network and querying end to end relation. Such design models as abstract, composite and role are adapted in the model to adapt the continuing changes of IP brearer network and its business. With data owned by a certain telecom coporation, a system is built and the end to end relation between MSS and MGW is implemented and showed, and it is verfied that the model can support inter-department resource assignment and inter-department alarm association anlysis.
