Telefónica Germany Migrates First 100,000 Customers' 4G/5G Voice Services to Mavenir Cloud-Native IMS Technology
Telefónica Germany has successfully migrated its first 100,000 customers to Mavenir's cloud-native IP Multimedia Subsystem (IMS) platform for 4G and 5G voice services, marking a significant milestone in the carrier's network modernization efforts. The migration represents a major technical achievement as the operator transitions both fixed and mobile subscriber bases to Mavenir's network-scale IMS solution deployed on Amazon Web Services (AWS). This implementation demonstrates the practical deployment of cloud-native telecommunications infrastructure for voice services across next-generation mobile networks. The migration showcases how traditional telecom operators are leveraging cloud-native architectures to modernize their core network functions, moving away from legacy hardware-based systems to more flexible, scalable cloud deployments for critical voice services.
Why It Matters
This migration represents a significant validation of cloud-native IMS technology for large-scale carrier deployments, demonstrating that major European operators are confident enough in cloud infrastructure to handle mission-critical voice services for hundreds of thousands of customers. The successful implementation on AWS also highlights the growing acceptance of public cloud platforms for telecommunications core network functions, which could accelerate similar migrations across the industry and drive further innovation in cloud-native telecom infrastructure.
