Utilize the 5G advantages at the Edge
• 5G allows rethinking of the end-to-end architecture
• The big drivers are service agility and cost (Capex & Opex)
• Edge has the flexible architectural component
o New and innovative applications will be placed
o Leverage bandwidth and latency advantages of 5G
• What are the applications?
• What is the context?
• What exposure mechanisms can we use?

System, Network Element etc.
O-RAN (Open RAN) architecture addresses some of these, however, the data collection as
specified here need to be implemented in a scalable and cost efficient way
