(Supplement-3)
5GMF Focus Areas in FG IMT-2020
1. Overall Architecture
Core
FH/BH UE
The focus areas for 5GMF representing in the matrix of system elements and layers.
Slicing of Fronthaul/ Backhaul is new area of study in IMT-2020 network aspect.
Infrastructure aspect of FH/BH is agreed to be handled in ITU-T SG15
Platform/
Middleware
Applications
4.Edge Computing
5. Softwarized Data Plane
(in support of e.g. ICN)
3. Horizontal Extension of Slicing
2. Vertical Extension of Slicing

8. Network softwarization view of the 5G mobile networks
(Supplement-4)
Network softwarization view of the 5G mobile networks
Slicing allows logically isolated network partitions (LINP)
A slice is considered as a unit of programmable resources such as network, computation and storage
As 5G Mobile Network should cover wider variety of application domains, the concept of slicing should be extended from what are currently targeted by SDN/NFV technologies.
