South Asian MNO Achieves 5G Readiness with Virtualized AAA Deployment 

How a leading South Asian operator deployed Alepo’s AAA Server to reduce costs while building 5G-ready network infrastructure. 

The Challenge: Future-Ready Infrastructure

One of South Asia’s largest mobile operators needed to modernize their AAA infrastructure to support growing subscriber demands while preparing for 5G deployment. Their legacy system couldn’t provide the customization, scalability, and advanced analytics needed for next-generation services. 

The operator required a virtualized solution that would reduce both CAPEX and OPEX while providing enhanced business intelligence capabilities and identifying revenue optimization opportunities. 

The Vision: Virtualized Network Functions

The MNO envisioned migrating to a virtualized AAA platform that would integrate seamlessly with their existing NFV infrastructure while providing advanced customization, enhanced analytics, and 5G-ready capabilities for future network evolution. 

The Solution: A Custom, Virtualized AAA Platform

Working with regional partners, Alepo deployed a comprehensive virtual AAA solution: 

• Virtualized Deployment: Complete vAAA platform with VNFM integration in the operator’s NFVi environment, including load balancer, database, monitoring, and reporting components. 

• Custom Authentication: Specialized capabilities supporting enterprise GPON/fiber subscribers and LTE traffic accounting with advanced coverage gap identification features. 

• 5G-Ready Architecture: Future-proof platform supporting slice authentication, DNN provisioning, and diverse next-generation use cases including non-3GPP network access. 

• Enhanced Analytics: Advanced BI capabilities enabling quick launch of targeted promotions while identifying revenue leaks and network optimization opportunities. 

The Results 

The deployment delivered measurable operational and financial benefits: 

• Zero-Downtime Migration: Seamless migration of 90,000+ subscribers across enterprise, GPON/fiber, and LTE services totaling 413,000 online sessions without service interruptions. 

• Reduced OPEX and CAPEX: Virtualized deployment eliminated physical server requirements while providing dynamic scalability, substantially lowering both operational and capital expenses. 

• Enhanced Revenue Performance: Improved BI capabilities enabled rapid launch of targeted promotions and reduced time-to-market while identifying and addressing revenue leakage issues. 

• Improved Network Coverage: The vAAA instantly identified low-coverage LTE areas and facilitated troubleshooting, enabling delivery of superior customer experience across the network. 

The Impact

The South Asian MNO’s virtualized transformation demonstrates how modern NFV-based solutions can simultaneously reduce costs and enhance capabilities while building foundations for 5G services. The customized approach addressed immediate operational needs while ensuring future readiness.
