Abstract:

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 softswitch 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.

Key words: SID, IP bearer network, information sharing, resource information model, end to end relation
