3G to 4G Migration

Migration of legacy 3G business services to 4G

Customer: Major European NatCo

Project management: SCRUM


Telecom operators nowadays are transforming their core networks from legacy 3G to modern 4G, enabling VoLTE and VoWiFi calling. Legacy CS services have to be integrated into the new 4G network via IMSSF or written anew. Business dedicated services are crucial for each operator, therefore special attention and focus are needed when doing service planning and rollout.

Various environments (like a test, reference, staging and others) are usually interconnected, with some network elements being shared by some or even all the environments – this implies a risk of affecting neighboring environments.
