Case Study: T-Mobile validates virtual EPC performance with Emblasoft Evolver

Validating migration to virtual EPC with T-Mobile

T-Mobile Croatia faced the challenge of migrating to a new, fully virtualized EPC core infrastructure. They needed to ensure this new architecture could deliver the expected performance and scale to support subscriber attachments, concurrent sessions, and complex traffic mixes without any negative impact on services. To validate their investment and avoid relying on unsubstantiated vendor claims, they turned to Emblasoft for a testing solution.

Using Emblasoft's Evolver test and validation solution, T-Mobile was able to comprehensively test the new virtual infrastructure with emulated live traffic before connecting real users. The solution enabled automated, granular testing of signalling capacity and user plane traffic, which successfully validated expected performance and identified a critical flaw in the system design. As a result, Emblasoft's testing provided the insights needed for a successful network redesign and migration, ensuring the project's outcome met performance goals.
