Telefónica Germany migrates 4G/5G voice services for first 100,000 customers to Mavenir's cloud-native IMS technology
Telefónica Germany has successfully migrated voice services for its first 100,000 4G and 5G customers to Mavenir's cloud-native IP Multimedia Subsystem (IMS) technology running on Amazon Web Services. This milestone represents a significant step in the operator's broader transformation initiative to modernize its telecommunications infrastructure by moving away from legacy circuit-switched voice systems to internet protocol-based communications. The migration involves deploying Mavenir's web-scale IMS solution, which is designed to handle both fixed and mobile subscriber bases within a unified cloud architecture. This approach allows Telefónica Germany to leverage the scalability and flexibility of AWS cloud infrastructure while maintaining voice service quality across its 4G and 5G networks. The successful migration of the initial customer cohort demonstrates the viability of cloud-native IMS deployments for large-scale telecom operations and sets the foundation for the operator to continue transitioning its entire subscriber base to the new platform.
Why It Matters
This deployment represents a significant validation of cloud-native network functions for core telecom services, demonstrating that critical voice infrastructure can be successfully migrated from traditional hardware-based systems to public cloud platforms. The move signals broader industry adoption of disaggregated, software-defined network architectures that can reduce operational costs and improve service agility for mobile operators.
