Telefónica Germany migrates 4G/5G voice services of its first 100,000 customers to Mavenir's cloud-native IMS technology
Telefónica Germany has successfully migrated voice services for its first 100,000 customers to Mavenir's cloud-native IP Multimedia Subsystem (IMS) technology running on Amazon Web Services. This migration represents a significant milestone in the operator's transition to cloud-based network infrastructure, moving both fixed and mobile subscribers to Mavenir's web-scale IMS solution. The deployment demonstrates the practical implementation of cloud-native telecommunications infrastructure at commercial scale, marking a shift from traditional hardware-based voice switching systems to software-defined network functions hosted in public cloud environments. This technical achievement showcases how major telecom operators are modernizing their core network services by leveraging cloud platforms for critical voice communication services across 4G and 5G networks.
Why It Matters
This migration represents a significant validation of cloud-native network functions for mission-critical telecommunications services. By successfully moving voice services to AWS-hosted IMS infrastructure, Telefónica Germany demonstrates that public cloud platforms can handle the stringent reliability and performance requirements of telecom core networks. This could accelerate industry adoption of cloud-native network architectures and influence other operators' infrastructure modernization strategies, particularly as they prepare for more advanced 5G services that require greater network flexibility and scalability.
