– Significantly improving agility and speeding up deployment of new services • XaaS creation time from “90 days to 90 mins”
– Creating opportunities for operators to buy, sell, and integrate XaaS in an automated and cost-effective manner
• Define and validate the 5G business actors and process, including economic and market mechanisms that promote efficiency of multi-domain services – Impact operator’s community by identifying new challenges or elaborating on
known ones
• Build a pan European multi-site sandbox testbed – To assess the feasibility and performance of the proposed architecture and business
models, by deploying the working end-to-end system built by 5GEx
• Standardize through strong industry participation of all major stakeholders • Provide Open Source solutions

› Virtualized RAN
– New functional split allows some RAN functions to run on run in a virtualized environment
– Flexible scalability and elasticity to minimize permanent peak rate dimensioning
› New deployment models
– Gives control to operator to support various deployment models, e.g. centralized or
distributed
– Support co-location of RAN and Core function
– Potential to provide added value services for third party applications
› Modular design
– Current DUs capacity underutilized for many deployments
– Modular design allows investing where it makes sense
› Use of merchant silicon
– Reprogrammable hardware allows repurposing of earlier investments instead of throwing
them out

› A live sandbox interconnecting five leading European operators, enabling automated end-to-end orchestration of multi-party 5G services to undergo accelerated prototyping and piloting prior to market launch. The 5GEx sandbox will be evolved and become a living in-operation lab after the project end
› A set of APIs enabling
service catalogue
publishing/sharing, rapid
provisioning and large
scale invocation of
composite services
across multiple
autonomous systems.
The APIs map to
reference points in the
NFV MANO stack, and
extend NFV services into
multi-actor wholesale
