Description:

The purpose of the project was to enable a new pricing concept that allowed to sell and enforce different maximum download speeds for different mobile subscriptions.

All systems along the call path had to be made compatible with this approach configuration changes had to be made and activated during low-traffic time windows.

This was a follow-up project to Project Manager/Coach AAA/PCRF (User Authentication and Policy Control) which built the technical capability to provide this functionality.

Responsibilities:

• Identified the services that needed to be migrated
• Prioritized the services for which the migration needed to be carried out based on technical and commercial criteria
• Developed a migration concept and aligned it with all stakeholders from the various entities (incl. marketing/product management, design, testing, operations and service management)
• Developed a migration plan that took in consideration the priority of the service as well as resource availability for implementation and live verification testing during as few nightshifts as possible at an acceptable risk level (incl. time for roll-backs in case of any major issues)
• Carried out the migration for all services successfully with only one minor issue which did not require a roll-back and could be fixed during live operation the same day
