Key Wireless Technology Directions
Main building blocks
Based on a new, unified, air interface (New Radio: NR - 5G-NR) and a new network architecture, to connect everything.
5G New Radio (NR) to “connect everything”:
A unified air interface.
Able to embrace all sort of wireless/wired accesses, sharing a common core (5G Core Network – 5GC).
5G new architecture to “interconnect everything”:
A common core network.
System arch. and functional modules
Separate the User Plane (UP) functions from the Control Plane (CP) functions.
Modularize the function design, e.g. to enable flexible and efficient network slicing.
Define procedures (i.e. the set of interactions between network functions) as services.
Enable each Network Function to interact with other NF directly if required (direct interaction).
Minimize dependencies between the Access Network (AN) and the Core Network (CN).
Support a unified authentication framework.
Support "stateless" NFs, where the "compute" resource is decoupled from the "storage" resource.
Support capability exposure.
Support concurrent access to local and centralized services. To support low latency services and access to local data networks, UP functions can be deployed close to the Access Network.
