Centralization and flat are characteristics of the core network structure. The advantages of this structure are resources sharing and fast deployment. However

potentialrisks are that server room

Poollevelredundancy technologies and methods are no longer able to controlrisks. This article aims at solving the issue mentioned above. Hence that

this article willdiscuss a redundancy ratio algorithm by using multirisks analysis and network capability analysis methods to achieve quantifying the redundancy capability within the VoLTE network Poolresources. Furthermore

the cross-Poolredundancy modelwhich based on this algorithm willbe developed to enhance the VoLTE core network redundancy capability and achieve fast recovery while major malfunction. The modelwillinclude the following methods: four leveldamage assessment
