5G Migration Scenario

Initial Stage of 5G deployment: 5G services to be provided by interwork between eLTE with existing frequency bands and New Radio(NR) with new frequency bands, i.e. Non Stand Alone(NSA)

Later stage of 5G deployment: NextGen CN to be deployed to provide services flexibly by architecture suit for slicing. NR to be deployed for the existing frequency bands. Support stand-alone NR.
