The Virtualized vNGN network is bringing important benefits to Vodafone Germany:
* Footprint and Cost Reduction compared to Vendor-Specific hardware;
* Consolidation of Infrastructure for different Telco Applications;
* Flexibility in software deployment and Elasticity in resources usage.
All SW functionalities implemented by former NGN solution have been guaranteed by vNGN, moreover IP-IP interconnection according to AKNN specifications (approved by German Telecommunication Authority) has been added thanks to vNGN.
The smooth and progressive migration from NGN to vNGN was realized guaranteeing minimum operational impact on OSS/BSS and Access Layers, preserving the same northbound interfaces and User equipment.
ITALTEL SOLUTION HIGHLIGHTS
Former NGN network, realized by Italtel proprietary stand-alone HW+SW nodes, has been migrated to vNGN solution adopting 3-layer model approach:
Commercial-Off-The-Shelf HW (VCE Vblock systems) to build the resource layer providing common computing resources and connectivity to the whole Telco network;
Hypervisor Layer (VMware vSphere/vCloud) allowing decoupling of the physical computation and storage resources from the Italtel Applications;
Italtel SW Applications providing the features and services required by Vodafone.
vNGN solution provides Transit functionalities and User Services both to residential and business customers.
The solution adopts the following Italtel applications:
Italtel i-MCS (Multimedia Communication Suite) as Call Control Element, deployed onto three geographical distributed Data Centers based on VCE Vblock systems;
Italtel i-TDS (The Data Suite) as Users and Services profiles database;
Italtel i-NEM (Neutral Element Manager), the Italtel comprehensive management suite.
