Telefónica Germany Migrates 100,000 First Customers' 4G/5G Voice Services to Mavenir's Cloud-Based IMS Technology
Telefónica Germany has successfully migrated its first 100,000 customers to Mavenir's cloud-based IP Multimedia Subsystem (IMS) running on Amazon Web Services, marking a significant milestone in the carrier's network modernization effort. The migration encompasses voice services for both 4G and 5G networks, representing a transition from traditional circuit-switched voice infrastructure to an internet-scale, cloud-native architecture. This deployment demonstrates the practical viability of running core telecom services on public cloud infrastructure, with Mavenir's IMS solution handling the real-time voice call processing and session management for both fixed and mobile subscriber bases. The successful migration establishes a foundation for Telefónica Germany to scale the cloud-based voice services across its entire customer base while potentially reducing operational costs and improving service flexibility.
Why It Matters
This migration represents a significant validation of cloud-native telecommunications infrastructure, demonstrating that critical real-time services like voice calling can successfully operate on public cloud platforms at carrier scale. The move signals broader industry acceptance of disaggregated, software-defined network architectures over traditional hardware-dependent systems, potentially accelerating similar migrations across the telecom sector and establishing new benchmarks for 5G service delivery models.
